Data on the epidemiology of alcoholic cirrhosis, especially in Asian countries, are limited. We compared the temporal evolution of patterns of alcoholic and nonalcoholic cirrhosis over the last decade. We retrospectively examined the inpatient datasets of five referral centers during 2002 and 2011. The study included patients who were admitted due to specific complications of liver cirrhosis. We compared the causes of hospital admissions and in-hospital deaths between patients with alcoholic and nonalcoholic cirrhosis. Among the included 2,799 hospitalizations (2,165 patients), 1,496 (1,143 patients) were from 2002, and 1,303 (1,022 patients) were from 2011. Over time, there was a reduction in the rate of hepatic encephalopathy (HE) as a cause of hospitalization and an increase in the rate of hepatocellular carcinoma. Deaths that were attributable to HE or spontaneous bacterial peritonitis (SBP) significantly decreased, whereas those due to hepatorenal syndrome (HRS) significantly increased over time in patients with alcoholic cirrhosis. However, in patients with nonalcoholic cirrhosis, hepatic failure and HRS remained the principal causes of in-hospital death during both time periods. The major causes of in-hospital deaths have evolved from acute cirrhotic complications, including HE or SBP to HRS in alcoholic cirrhosis, whereas those have remained unchanged in nonalcoholic cirrhosis during the last decade.

Death audits have been used to describe pediatric mortality in under-resourced settings, where record keeping is often a challenge. This information provides the cornerstone for the foundation of quality improvement initiatives. Malawi, located in sub-Saharan Africa, currently has an Under-5 mortality rate of 64/1000. Kamuzu Central Hospital, in the capital city Lilongwe, is a busy government referral hospital, which admits up to 3000 children per month. A study published in 2013 reported mortality rates as high as 9%. This is the first known audit of pediatric death files conducted at this hospital. A retrospective chart review on all pediatric deaths that occurred at Kamuzu Central Hospital (excluding deaths in the neonatal nursery) during a 13-month period was done using a standardized death audit form. A descriptive analysis was completed, including patient demographics, HIV and nutritional status, and cause of death. Modifiable factors were identified that may have contributed to mortality, including a lack of vital sign collection, poor documentation, and delays in the procurement or results of tests, studies, and specialist review. Seven hundred forty three total pediatric deaths were recorded and 700 deceased patient files were reviewed. The mortality rate by month ranged from a low of 2.2% to a high of 4.4%. Forty-four percent of deaths occurred within the first 24 h of admission, and 59% occurred within the first 48 h. The most common causes of death were malaria, malnutrition, HIV-related illnesses, and sepsis. The mortality rate for this pediatric referral center has dramatically decreased in the 6 years since the last published mortality data, but remains high. Areas identified for continued development include improved record keeping, improved patient assessment and monitoring, and more timely and reliable provision of testing and treatment. This study demonstrates that in low-resource settings, where reliable record keeping is often difficult

Full Text Available Abstract Background Respiratory alarm monitoring and rapid response team alerts on hospital general floors are based on detection of simple numeric threshold breaches. Although some uncontrolled observation trials in select patient populations have been encouraging, randomized controlled trials suggest that this simplistic approach may not reduce the unexpected death rate in this complex environment. The purpose of this review is to examine the history and scientific basis for threshold alarms and to compare thresholds with the actual pathophysiologic patterns of evolving death which must be timely detected. Methods The Pubmed database was searched for articles relating to methods for triggering rapid response teams and respiratory alarms and these were contrasted with the fundamental timed pathophysiologic patterns of death which evolve due to sepsis, congestive heart failure, pulmonary embolism, hypoventilation, narcotic overdose, and sleep apnea. Results In contrast to the simplicity of the numeric threshold breach method of generating alerts, the actual patterns of evolving death are complex and do not share common features until near death. On hospital general floors, unexpected clinical instability leading to death often progresses along three distinct patterns which can be designated as Types I, II and III. Type I is a pattern comprised of hyperventilation compensated respiratory failure typical of congestive heart failure and sepsis. Here, early hyperventilation and respiratory alkalosis can conceal the onset of instability. Type II is the pattern of classic CO2 narcosis. Type III occurs only during sleep and is a pattern of ventilation and SPO2 cycling caused by instability of ventilation and/or upper airway control followed by precipitous and fatal oxygen desaturation if arousal failure is induced by narcotics and/or sedation. Conclusion The traditional threshold breach method of detecting instability on hospital wards was not

Hospital-acquired infections with Staphylococcus aureus, especially methicillin-resistant S. aureus (MRSA) infections, are a major cause of illness and death and impose serious economic costs on patients and hospitals. However, the recent magnitude and trend of these infections have not been reported. We used national hospitalization and resistance data to estimate the annual number of hospitalizations and deaths associated with S. aureus and MRSA from 1999 through 2005. During this period, t...

This study aims at comparing weekday deaths to weekend deaths of in-patients of a tertiary hospital in Nigeria. This is a 10-year retrospective survey conducted at the Nnamdi Azikiwe University Teaching Hospital in which the death records of the hospital were accessed from the various wards and health records department to extract relevant data pertaining to the time of hospital death. Tests of statistical significance were done using Chi-square test at 95% confidence intervals. A total of 3934 deaths were recorded during the period of study. The ages ranged from a few hours to 94 years with a mean age of 38.5 years. The male to female ratio was 1.2:1. An average of 547 weekend deaths and 568 weekday deaths were recorded, giving a ratio of 0.96:1. A ratio of weekend to weekday death rate of 0.99:1 and 0.93:1 for the males and females, respectively was noted. The labor ward, followed by the intensive care unit (ICU) had the highest weekend to weekday death ratio of 1.72:1 ( P = 0.0461) and 1.41:1 ( P = 0.1440), respectively. Weekend deaths were less in the other wards, with the gynaecological ward having the least ratio of 0.63:1 ( P = 0.7360). The rate of hospital deaths was generally found not to vary significantly over the weekends and weekdays in the hospital except for the labor ward which had significantly higher weekend to weekday death rates of 1.72:1. There is therefore need for confidential enquiry into the causes of hospital deaths, especially in the labor ward, in order to identify and prevent avoidable deaths.

First, to evaluate the influence of comorbid diseases and concomitant injuries on the risk of in-hospital death after traumatic spinal cord injury (TSCI). Second, to identify the risk characteristics of TSCI patients with likelihood of death. Population-based retrospective cohort study. Sixty-two acute care hospitals in South Carolina, USA. Records of 3389 TSCI patients hospitalized with acute TSCI were evaluated. Days elapsing from the date of injury to date of death established the survival time (T). Cox regression examined risk of in-hospital death as a function of counts of comorbid conditions and injuries along with their joint effects controlling for other covariates. Counts of comorbid conditions and injuries showed dose-dependent risk of death while in-hospital independent of demographical and clinical covariates. Hazard ratios (HR) for counts 3+, 2 and 1 comorbid conditions were 2.19 (P<0.001), 1.73 (P=0.005) and 1.20 (P=0.322), respectively. For counts of 4+, 3 and 2 other injuries were 1.85 (P<0.001), 1.81 (P<0.001) and 1.46 (P=0.022), respectively. The joint effect of the two was transadditive with statistically significant HR ranging from 1.72-3.14. Counts of comorbid conditions and injured body regions strongly indicate risk of in-hospital death after TSCI and their joint effects elicited dose-dependent gradient independent of demographical and clinical covariates. Assessing risk of in-hospital death based on joint use of counts of comorbid diseases and injuries is highly informative to target TSCI patients at high risk of dying.

Rotavirus is the leading cause of hospitalizations and deaths from diarrhea. 33 African countries had introduced rotavirus vaccines by 2016. We estimate reductions in rotavirus hospitalizations and deaths for countries using rotavirus vaccination in national immunization programs and the potential of vaccine introduction across the continent. Areas covered: Regional rotavirus burden data were reviewed to calculate hospitalization rates, and applied to under-5 population to estimate baseline hospitalizations. Rotavirus mortality was based on 2013 WHO estimates. Regional pre-licensure vaccine efficacy and post-introduction vaccine effectiveness studies were used to estimate summary effectiveness, and vaccine coverage was applied to calculate prevented hospitalizations and deaths. Uncertainties around input parameters were propagated using boot-strapping simulations. In 29 African countries that introduced rotavirus vaccination prior to end 2014, 134,714 (IQR 112,321-154,654) hospitalizations and 20,986 (IQR 18,924-22,822) deaths were prevented in 2016. If all African countries had introduced rotavirus vaccines at benchmark immunization coverage, 273,619 (47%) (IQR 227,260-318,102) hospitalizations and 47,741 (39%) (IQR 42,822-52,462) deaths would have been prevented. Expert commentary: Rotavirus vaccination has substantially reduced hospitalizations and deaths in Africa; further reductions are anticipated as additional countries implement vaccination. These estimates bolster wider introduction and continued support of rotavirus vaccination programs.

To examine the effect of underlying maternal morbidities on the odds of maternal death during delivery hospitalization. We used data that linked birth certificates to hospital discharge diagnoses from singleton live births at 22 weeks of gestation or later during 1995-2003 in New York City. Maternal morbidities examined included prepregnancy weight more than 114 kilograms (250 pounds), chronic hypertension, pregestational or gestational diabetes mellitus, chronic cardiovascular disease, pulmonary hypertension, chronic lung disease, human immunodeficiency virus (HIV), and preeclampsia or eclampsia. Associations with maternal mortality were estimated using multivariate logistic regression. During the specified time period, 1,084,862 live singleton births and 132 maternal deaths occurred. Patients with increasing maternal age, non-Hispanic black ethnicity, self-pay or Medicaid, primary cesarean delivery, and premature delivery had higher rates of maternal mortality during delivery hospitalization. From the entire study population, 4.1% had preeclampsia or eclampsia (n=44,004), 1.8% had chronic hypertension (n=19,647), 1.1% of patients were classified as obese (n=11,936), 0.7% had pregestational diabetes (n=7,474), 0.4% had HIV (n=4,665), and 0.01% had pulmonary hypertension (n=166). Preeclampsia or eclampsia (adjusted odds ratio [OR], 8.1; 95% confidence interval [CI], 5.5-12.1), chronic hypertension (adjusted OR, 7.7; 95% CI 4.7-12.5), underlying maternal obesity (adjusted OR, 2.9; 95% CI 1.1-8.1), pregestational diabetes (adjusted OR, 3.3; 95% CI 1.3-8.1), HIV (adjusted OR, 7.7; 95% CI 3.4-17.8), and pulmonary hypertension (adjusted OR, 65.1; 95% CI 15.8-269.3) were associated with an increased risk of death during the delivery hospitalization. The presence of maternal disease significantly increases the odds of maternal mortality at the time of delivery hospitalization. II.

Full Text Available Introduction: All pregnant women are at risk of obstetrical complications which occurs during labour and delivary that lead to maternal death. Here to report a 10 year review of maternal mortality ratio in "Paropakar Maternity and Women's Hospital (PMWH" Thapathali Kathmandu, Nepal. Methods: Medical records of 66 maternal deaths were reviewed to study the likely cause of each death over the study period. Results: There were a total of 66 maternal deaths. While 192487 deliveries conducted over the 10 year period. The maternal mortality ratio (MMR was 356.64/100000 live birth. The highest MMR of 74.22/100,000 was observed in 2059 and lowest was 17.42/100,000 in 2068 B.S. Leading cause of MMR was remained hemorrhage accounting for 30.30% followed by eclampsia 24.24%. Sepsis, suspected cases of pulmonary embolism and amniotic fluid embolism each contributing 15.15%, 4.54% and 3.03% respectively. Where as anesthetic complication and abortion constiuates 6.06 % each equally for maternal death. The death noted in older women (30+year were 36.36%. Primipara accounted for more deaths (51.51%. Conclusions: The fall in maternal mortality rate has been observed except for year 2063 BS. Haemorrhage is the main contributing cause behind maternal mortality.

According to the Quality of Death Index, Hong Kong is lagging behind many other Western and Asian countries in the category of palliative and healthcare. To ensure the provision of high-quality palliative care, it is important to explore the self-competence of health and social care workers in coping with death work including palliative care. This region-wide study aims to assess the level of self-competence with a validated Self-Competence in Death Work Scale (SC-DWS) and examine its correlates. The SC-DWS was administered to a cross-sectional convenience sample of health and social care workers across eight healthcare institutions between January and October 2016. Total scores for the 16-item SC-DWS and its Existential and Emotional subscales were calculated. We then examined sociodemographic variables (e.g., age, profession, place of employment) in relation to the total and subscale scores using multiple linear regression. Coding was conducted on responses to a final open-ended question asking about the personal views of the workers towards their self-competence in death work. We collected data from 885 health and social care workers. Mean score of the SC-DWS was 60.16 (range: 16 - 80), while its Existential and Emotional subscales scored 37.90 (range: 10 - 50) and 14.46 (range: 4 - 20) respectively. Four categories of personal view towards self-competence in death work including (1) personal resources; (2) existential challenges and coping; (3) emotional challenges and coping; and (4) personal recommendations on improving self-competence were identified. In multivariate analyses, workers aged 50 or above, divorced, working in Hospice A, Rehabilitation Hospital B (where a quality improvement initiative in end-of-life care was implemented) and Acute Hospital B (a Christian institution with strong caring culture) and with personal bereavement experience had significantly higher scores, whereas nurses scored significantly lower than less-educated personal care

The purpose of the present study was to identify characteristics of visiting nurse agencies (VNA) in Japan with high home death rates by a prefecture-wide survey. A cross-sectional study of visiting nurse agencies (n = 101) in Ibaraki Prefecture, Japan, was completed. Data included the basic characteristics of each VNA, the type of services provided, level of coordination with other service providers, total number of VNA patients who died per year and place of death and contractual relationship with home-care supporting clinics providing end-of-life care services in the home 24 h a day. The VNA characteristics were analyzed by logistic regression, using the home death rate per VNA as a dependent variable. A total 69 agencies, excluding those that did not report number of deaths (n = 14) and those without deaths during the year (n = 6), were analyzed. The median home death rate of the 69 VNA was 29.8%. The results of logistic regression analysis showed that higher home death rate was significantly associated with lack of attachment to a hospital, existence of a contractual relationship with home-care supporting clinics and existence of an interactive information exchange through telephone/face-to-face communication with attending physicians. In order to increase the home death rate of people using VNA, policymakers must consider establishing home-based service systems within the community that can provide home end-of-life care services 24 h a day, and support the interactive exchange of information between the visiting nurse and the attending physician. © 2014 The Authors.

The government of Ghana and key stakeholders have put into place several interventions aimed at reducing maternal deaths. At the institutional level, the conduct of maternal deaths audit has been instituted. This also contributes to reducing maternal deaths as shortcomings that may have contributed to such deaths could be identified to inform best practice and forestall such occurrences in the future. The objective of this study was to review the quality of maternal care in a regional hospital. A review of maternal deaths using Quality of Care Evaluation Form adapted from the Komfo Anokye Teaching Hospital (KATH) Maternal Death Audit Evaluation Committee was used. About fifty-five percent, 18 (55%) of cases were deemed to have received adequate documentation, senior clinicians were involved in 26(85%) of cases. Poor documentation, non-involvement of senior clinicians in the management of cases, laboratory related issues particularly in relation to blood and blood products as well as promptness of care and adequacy of intensive care facilities and specialists in the hospital were contributory factors to maternal deaths . These are common themes contributing to maternal deaths in developing countries which need to be urgently tackled. Maternal death review with emphasis on quality of care, coupled with facility gap assessment, is a useful tool to address the adequacy of emergency obstetric care services to prevent further maternal deaths.

Death certificates (DC) can provide valuable health status data regarding disease incidence, prevalence and mortality in a community. It can guide local health policy and help in setting priorities. Incomplete and inaccurate DC data, on the other hand, can significantly impair the precision of a national health information database. In this study we evaluated the accuracy of death certificates at a tertiary care teaching hospital in a Karachi, Pakistan. A retrospective study conducted at Aga Khan University Hospital, Karachi, Pakistan for a period of six months. Medical records and death certificates of all patients who died under adult medical service were studied. The demographic characteristics, administrative details, co-morbidities and cause of death from death certificates were collected using an approved standardized form. Accuracy of this information was validated using their medical records. Errors in the death certificates were classified into six categories, from 0 to 5 according to increasing severity; a grade 0 was assigned if no errors were identified, and 5, if an incorrect cause of death was attributed or placed in an improper sequence. 223 deaths occurred during the study period. 9 certificates were not accessible and 12 patients had incomplete medical records. 202 certificates were finally analyzed. Most frequent errors pertaining to patients' demographics (92%) and cause/s of death (87%) were identified. 156 (77%) certificates had 3 or more errors and 124 (62%) certificates had a combination of errors that significantly changed the death certificate interpretation. Only 1% certificates were error free. A very high rate of errors was identified in death certificates completed at our academic institution. There is a pressing need for appropriate intervention/s to resolve this important issue.

The objective of the study was to evaluate practices in Spanish hospitals after intrauterine death in terms of medical/ technical care and bereavement support care. A cross-sectional descriptive study using an online self-completion questionnaire. The population was defined as women who had experienced an intrauterine fetal death between sixteen weeks and birth, either through spontaneous late miscarriage/stillbirth or termination of pregnancy for medical reasons. Respondents were recruited through an online advertisement on a stillbirth charity website and social media. The analysis used Pearson's chi-squared (p ≤ 0.05) test of independence to cross-analyse for associations between objective measures of care quality and independent variables. Responses from 796 women were analysed. Half of the women (52.9%) had postmortem contact with their baby. 30.4% left the hospital with a least one linking object or a photograph. In 35.8% of cases parents weren't given any option to recover the body/remains. 22.9% of births ≥26 weeks gestation were by caesarean, with a significant (p < 0.001) difference between public hospitals (16.8%) and private hospitals (41.5%). 29.3% of respondents were not accompanied during the delivery. 48.0% of respondents recalled being administered sedatives at least once during the hospital stay. The autopsy rate in stillbirth cases (≥ 20 weeks) was 70.5% and 44.4% in cases of termination of pregnancy (all gestational ages). Consistent significant (p < 0.05) differences in care practices were found based on gestational age and type of hospital (public or private), but not to other variables related to socio-demographics, pregnancy history or details of the loss/death. Intrauterine deaths at earlier gestational ages received poorer quality care. Supportive healthcare following intrauterine death is important to women's experiences in the hospital and beneficial to the grief process. Many care practices that are standard in

The Lombardy region in northern Italy ranks among the most air polluted areas of Europe. Previous studies showed air pollution short-term effects on all-cause mortality. We examine here the effects of particulate matter with aerodynamic diameter ≤10µm (PM10) and nitrogen dioxide (NO2) exposure on deaths and hospitalizations from specific causes, including cardiac, cerebrovascular and respiratory diseases. We considered air pollution, mortality and hospitalization data for a non-opportunistic sample of 18 highly polluted and most densely populated areas of the region in the years 2003-2006. We obtained area-specific effect estimates for PM10 and NO2 from a Poisson regression model on the daily number of total deaths or cause-specific hospitalizations and then combined them in a Bayesian random-effects meta-analysis. For cause-specific mortality, we applied a case-crossover analysis. Age- and season-specific analyses were also performed. Effect estimates were expressed as percent variation in mortality or hospitalizations associated with a 10µg/m(3) increase in PM10 or NO2 concentration. Natural mortality was positively associated with both pollutants (0.30%, 90% Credibility Interval [CrI]: -0.31; 0.78 for PM10; 0.70%, 90%CrI: 0.10; 1.27 for NO2). Cardiovascular deaths showed a higher percent variation in association with NO2 (1.12%, 90% Confidence Interval [CI]: 0.14; 2.11), while the percent variation for respiratory mortality was highest in association with PM10 (1.64%, 90%CI: 0.35; 2.93). The effect of both pollutants was more evident in the summer season. Air pollution was also associated to hospitalizations, the highest variations being 0.77% (90%CrI: 0.22; 1.43) for PM10 and respiratory diseases, and 1.70% (90%CrI: 0.39; 2.84) for NO2 and cerebrovascular diseases. The effect of PM10 on respiratory hospital admissions appeared to increase with age. For both pollutants, effects on cerebrovascular hospitalizations were more evident in subjects aged less than

(1) To determine the relationship of incident delirium during hospitalization with 90-day mortality; (2) to identify potential in-hospital mediators through which delirium increases 90-day mortality. Analysis of data from Project Recovery, a controlled clinical trial of a delirium prevention intervention from 1995 to 1998 with follow-up through 2000. Large academic hospital. Patients ≥70 years old without delirium at hospital admission who were at intermediate-to-high risk of developing delirium and received usual care only. (1) Incident delirium; (2) potential mediators of delirium on death including use of restraining devices (physical restraints, urinary catheters), development of hospital acquired conditions (HACs) (falls, pressure ulcers), and exposure to other noxious insults (sleep deprivation, acute malnutrition, dehydration, aspiration pneumonia); (3) death within 90 days of admission. Among 469 patients, 70 (15%) developed incident delirium. These patients were more likely to experience restraining devices (37% vs 16%, P delirium was 4.2 (95% CI = 2.8-6.3) in bivariable analyses, increased in a graded manner with additional exposures to restraining devices, HACs, and other noxious insults, and declined by 10.9% after addition of these potential mediator categories, providing evidence of mediation. Restraining devices, HACs, and additional noxious insults were more frequent among patients with delirium, increased mortality in a graded manner, and were responsible for a significant percentage of the association of delirium with death. Additional efforts to prevent potential downstream mediators through which delirium increases mortality may help to improve outcomes among hospitalized older adults. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

To explore the major risk factors linking preoperative characteristics and anaesthesia-related death in dogs in referral hospitals in Japan. Observational cohort study. From April 1, 2010 to March 31, 2011, 4323 dogs anaesthetized in 18 referral hospitals in Japan. Questionnaire forms were collated anonymously. Death occurring within 48 hours after extubation was considered as an anaesthesia-related death. Patient outcome (alive or dead) was set as the outcome variable. Preoperative general physical characteristics, complete blood cell counts, serum biochemical examinations and intraoperative complications were set as explanatory variables. The risk factors for anaesthesia-related death were evaluated using chi-square test or Fisher's exact test, followed by multivariable logistic regression analysis of the data. Significance was set at p 15,200 μL -1 (16/499; 3.4%; 95% CI, 1.9-5.5) and American Society of Anesthesiologists grade III-V (19/1092; 1.7%; 95% CI, 1.1-2.7) were identified as risk factors for anaesthesia-related death. Intraoperative hypoxaemia (8/34; 23.5%; 95% CI, 10.7-41.2) and tachycardia (4/148; 2.7%; 95% CI, 0.7-6.8) were also risk factors for anaesthesia-related death. The results revealed that certain preoperative characteristics were associated with increased odds of anaesthesia-related death, specifically low serum glucose concentration and disturbances of consciousness. Greater attention to correcting preanaesthetic patient abnormalities may reduce the risk of anaesthesia-related death.

The location where death occurs varies widely among societies. The aim of this study was to describe the evolution in the hospital mortality rate (HMR) in Spain over the course of 20years and its distribution by province during a more recent period and to explore its relationship with potential explanatory variables. This was an ecological study. The population mortality rates were obtained from the Natural Population Movement (Movimiento Natural de la Población), and the hospital mortality rates were obtained from the Specialised Care Information System (Sistema de Información en Atención Especializada), which includes information from all hospitals in Spain. We calculated the mortality rates for patients who were not surveyed and the HMR at the national level between 1996 and 2015 and for provinces between 2013 and 2015. The relationship between the provincial distribution of HMR and various demographic, socioeconomic and healthcare variables were analysed through simple and multiple linear regression. The HMR in Spain increased from 49% in 1996 to 56% in 2007, having remained stable from 1996 to 2015. The variation among provinces was 40% to 70%. The multivariate analysis showed a higher HMR in the less rural provinces and in those with a larger availability of hospital beds. There is considerable provincial heterogeneity in Spain in terms of the probability of dying in hospital or at home. This result could be partly explained by demographics (percentage of rural population) and the healthcare structure (number of hospital beds per population).

Full Text Available Abstract Background Hospitalization for heart failure (HF is associated with high-in-hospital and short- and long-term post discharge mortality. Age and gender are important predictors of mortality in hospitalized HF patients. However, studies assessing short- and long-term risk of death stratified by age and gender are scarce. Methods A nationwide cohort was identified (ICD-9 codes 402, 428 and followed through linkage of national registries. The crude 28-day, 1-year and 5-year mortality was computed by age and gender. Cox regression models were used for each period to study sex differences adjusting for potential confounders (age and comorbidities. Results 14,529 men, mean age 74 ± 11 years and 14,524 women, mean age 78 ± 11 years were identified. Mortality risk after admission for HF increased with age and the risk of death was higher among men than women. Hazard ratio's (men versus women and adjusted for age and co-morbidity were 1.21 (95%CI 1.14 to 1.28, 1.26 (95% CI 1.21 to 1.31, and 1.28 (95%CI 1.24 to 1.31 for 28 days, 1 year and 5 years mortality, respectively. Conclusions This study clearly shows age- and gender differences in short- and long-term risk of death after first hospitalization for HF with men having higher short- and long-term risk of death than women. As our study population includes both men and women from all ages, the estimates we provide maybe a good reflection of 'daily practice' risk of death and therefore be valuable for clinicians and policymakers.

Environmental contamination has been associated with over half of methicillin-resistant Staphylococcus aureus (MRSA) outbreaks in hospitals. We explored if a hospital-wide environmental and patient cleaning protocol would lower hospital acquired MRSA rates and associated costs. This study evaluates the impact of implementing a hospital-wide environmental and patient cleaning protocol on the rate of MRSA infection and the potential cost benefit of the intervention. A retrospective, pre-post interventional study design was used. The intervention comprised a combination of enhanced environmental cleaning of high touch surfaces, daily washing of patients with benzalkonium chloride, and targeted isolation of patients with active infection. The rate of MRSA infection per 1000 patient days (PD) was compared with the rate after the intervention (Steiros Algorithm ® ) was implemented. A cost-benefit analysis based on the number of MRSA infections avoided was conducted. The MRSA rates decreased by 96% from 3.04 per 1000 PD to 0.11 per 1000 PD ( P reduction in MRSA infections, avoided an estimated $1,655,143 in healthcare costs. Implementation of this hospital-wide protocol appears to be associated with a reduction in the rate of MRSA infection and therefore a reduction in associated healthcare costs.

Increasing hospital market concentration (with concomitantly decreasing hospital market competition) may be associated with rising hospital prices. Hospital markup - the relative increase in price over costs - has been associated with greater hospital market concentration. Patients undergoing a cardiothoracic or gastrointestinal procedure in the 2008-2011 Nationwide Inpatient Sample (NIS) were identified and linked to Hospital Market Structure Files. The association between market concentration, hospital markup and hospital for-profit status was assessed using mixed-effects log-linear models. A weighted total of 1,181,936 patients were identified. In highly concentrated markets, private for-profit status was associated with an 80.8% higher markup compared to public/private not-for-profit status (95%CI: +69.5% - +96.9%; p markup compared to public/private not-for-profit status in unconcentrated markets (95%CI: +45.4% - +81.1%; p markup. Government and private not-for-profit hospitals employed lower markups in more concentrated markets, whereas private for-profit hospitals employed higher markups in more concentrated markets.

2014-01-01

We hypothesised that among nursing home decedents, nursing home for-profit status and poor quality-of-care ratings, as well as patient characteristics, would lower the likelihood of transfer to hospital prior to heart disease death. Using death certificates from a large metropolitan area (Tampa Florida Metropolitan Statistical Area) for 1998-2002, we geocoded residential street addresses of heart disease decedents to identify 2172 persons who resided in nursing homes (n=131) at the time of death. We analysed decedent place of death as an indicator of transfer prior to death. Multilevel logistic regression modelling was used for analysis. Cause of death and decedent characteristics were obtained from death certificates. Nursing home characteristics, including state inspector ratings for multiple time points, were obtained from Florida's Agency for Healthcare Administration. Nursing home for-profit status, level of nursing care and quality-of-care ratings were not associated with the likelihood of transfer to hospital prior to heart disease death. Nursing homes >5 miles from a hospital were more likely to transfer decedents, compared with facilities located close to a hospital. Significant predictors of no transfer for nursing home residents were being white, female, older, less educated and widowed/unmarried. In this study population, contrary to our hypotheses, sociodemographic characteristics of nursing home decedents were more important predictors of no transfer prior to cardiac death than quality rankings or for-profit status of nursing homes.

Selenium is an essential trace element and circulating selenium concentrations have been associated with a wide range of diseases. Candidate gene studies suggest that circulating selenium concentrations may be impacted by genetic variation; however, no study has comprehensively investigated...... this hypothesis. Therefore, we conducted a two-stage genome-wide association study to identify genetic variants associated with serum selenium concentrations in 1203 European descents from two cohorts: the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening and the Women’s Health Initiative (WHI). We...... tested association between 2,474,333 single nucleotide polymorphisms (SNPs) and serum selenium concentrations using linear regression models.

There are conflicting data about gender differences in short-term mortality after acute myocardial infarction (AMI) after adjusting for age and other prognostic factors. Therefore, we investigated the risk profile, clinical presentation, in-hospital mortality and mechanisms of death in women and men after the first AMI. The data was obtained from a chart review of 3382 consecutive patients, 1184 (35%) women (69.7+-10.9 years) and 2198 (65%) men (63.5+-11.8 years) with first AMI. The effect of gender and its interaction with age, risk factors and thrombolytic therapy on overall mortality and mechanisms of death were examined using logistic regression. Unadjusted in-hospital mortalty was higher in women (OR 1.77, 95% CI 1.47-2.15). Adjustment that included both age only and age and other base-line differences (Hypertension, diabetes mellitus, hypercholesterolemia, smoking, AMI type, AMI site, mean peak CK value, thrombolytic therapy)decreased the magnitude of the relative risk of women to men but did not eliminate it (OR 1.26, 95% CI 1.03-1.54 and OR 1.31 95% CI 1.03-1.66, respectively). Multivariate analysis revealed that female gender was an independent predictor of in-hospital mortality after the first AMI. Women were dying more often because of mechanical complications-refractory pulmonary edema and cardiogenic shock (P=0.02) or electromechanical dissociation (P=0.03), and men were dying mostly by arrhythmic death, primary ventricular tachycardia/fibrillation (P=0.002). Female gender was independently associated with mechanical death (OR 1.56, 95% CI 1.35-2.58; P=0.01) and anterior AMI was independently associated with arrhythmic death (OR 0.54, 95% CI 0.34-0.86; P=0.01). Our result demonstrate significant differences in mechanisms of in-hospital death after the first AMI in women, and men, suggesting the possibility that higher in-hospital mortality in women exists primarily because of the postponing AMI death due to the gender-related differences in

Studies demonstrating that higher doses of citalopram (> 40 mg) and escitalopram (> 20 mg) prolong the corrected QT interval prompted regulatory agency warnings, which are controversial, given the absence of confirmatory clinical outcome studies. We compared the risk of potential arrhythmia-related deaths for high doses of these selective serotonin reuptake inhibitors (SSRIs) to that for equivalent doses of fluoxetine, paroxetine, and sertraline. The Tennessee Medicaid retrospective cohort study included 54,220 persons 30-74 years of age without cancer or other life-threatening illness who were prescribed high-dose SSRIs from 1998 through 2011. The mean age was 47 years, and 76% were female. Demographic characteristics and comorbidity for individual SSRIs were comparable. Because arrhythmia-related deaths are typically sudden and occur outside the hospital, we analyzed out-of-hospital sudden unexpected death as well as sudden cardiac deaths, a more specific indicator of proarrhythmic effects. The adjusted risk of sudden unexpected death for citalopram did not differ significantly from that for the other SSRIs. The respective hazard ratios (HRs) for citalopram versus escitalopram, fluoxetine, paroxetine, and sertraline were 0.84 (95% CI, 0.40-1.75), 1.24 (95% CI, 0.75-2.05), 0.75 (95% CI, 0.45-1.24), and 1.53 (95% CI, 0.91-2.55). There were no significant differences for sudden cardiac death or all study deaths, nor were there significant differences among high-risk patients (≥ 60 years of age, upper quartile baseline cardiovascular risk). Escitalopram users had no significantly increased risk for any study end point. We found no evidence that risk of sudden unexpected death, sudden cardiac death, or total mortality for high-dose citalopram and escitalopram differed significantly from that for comparable doses of fluoxetine, paroxetine, and sertraline. © Copyright 2016 Physicians Postgraduate Press, Inc.

Reporting of meticillin-resistant and -susceptible Staphylococcus aureus on death certificates in Irish hospitals.

LENUS (Irish Health Repository)

Collins, C J

2011-02-01

The documentation of infection with meticillin-resistant Staphylococcus aureus (MRSA) on death certificates has been the subject of considerable public discussion. Using data from five tertiary referral hospitals in Ireland, we compared the documentation of MRSA and meticillin-susceptible S. aureus (MSSA) on death certificates in those patients who died in hospital within 30 days of having MRSA or MSSA isolated from blood cultures. A total of 133 patients had MRSA or MSSA isolated from blood cultures within 30 days of death during the study period. One patient was excluded as the death certificate information was not available; the other 132 patients were eligible for inclusion. MRSA and MSSA were isolated from blood cultures in 59 (44.4%) and 74 (55.6%) cases respectively. One patient was included as a case in both categories as both MRSA and MSSA were isolated from a blood culture. In 15 (25.4%) of the 59 MRSA cases, MRSA was documented on the death certificate. In nine (12.2%) of the 74 patients with MSSA cases, MSSA was documented on the death certificate. MRSA was more likely to be documented on the death certificate than MSSA (odds ratio: 2.46; 95% confidence interval: 1.01-6.01; P < 0.05). These findings indicate that there may be inconsistencies in the way organisms and infections are documented on death certificates in Ireland and that death certification data may underestimate the mortality related to certain organisms. In particular, there appears to be an overemphasis by certifiers on the documentation of MRSA compared with MSSA.

Mercury (Hg) and Hg-containing products are used in a wide range of settings in hospitals. Hg pollution control measures were carried out in the pediatric ward of a hospital to decrease the possibility of Hg pollution occurring and to decrease occupational Hg exposure. Total gaseous Hg (TGM) concentrations in the pediatric ward and hair and urine Hg concentrations for the pediatric staff were determined before and after the Hg pollution control measures had been implemented. A questionnaire survey performed indicated that the pediatric staff had little understanding of Hg pollution and that appropriate disposal techniques were not always used after Hg leakage. TGM concentrations in the pediatric ward and urine Hg (UHg) concentrations for the pediatric staff were 25.7 and 22.2% lower, respectively, after the Hg pollution control measures had been implemented than before, which indicated that the control measures were effective. However, TGM concentrations in the pediatric ward remained significantly higher than background concentrations and UHg concentrations for the pediatric staff were remained significantly higher than the concentrations in control group, indicating continued existence of certain Hg pollution.

Premature mortality is a public health concern that can be quantified as years of potential life lost (YPLL). Studying premature mortality can help guide hospital initiatives and resource allocation. We investigated the categories of neurologic and neurosurgical conditions associated with in-hospital deaths that account for the highest YPLL and their trends over time. Using the Nationwide Inpatient Sample (NIS), we calculated YPLL for patients hospitalized in the USA from 1988 to 2011. Hospitalizations were categorized by related neurologic principal diagnoses. An estimated 2,355,673 in-hospital deaths accounted for an estimated 25,598,566 YPLL. The traumatic brain injury (TBI) category accounted for the highest annual mean YPLL at 361,748 (33.9% of total neurologic YPLL). Intracerebral hemorrhage, cerebral ischemia, subarachnoid hemorrhage, and anoxic brain damage completed the group of five diagnoses with the highest YPLL. TBI accounted for 12.1% of all inflation adjusted neurologic hospital charges and 22.4% of inflation adjusted charges among neurologic deaths. The in-hospital mortality rate has been stable or decreasing for all of these diagnoses except TBI, which rose from 5.1% in 1988 to 7.8% in 2011. Using YPLL, we provide a framework to compare the burden of premature in-hospital mortality on patients with neurologic disorders, which may prove useful for informing decisions related to allocation of health resources or research funding. Considering premature mortality alone, increased efforts should be focused on TBI, particularly in and related to the hospital setting. Copyright © 2014 Elsevier Ltd. All rights reserved.

Despite decades of efforts to eliminate tuberculosis (TB) in the United States (US), TB still contributes to adverse ill health, especially among racial/ethnic minorities. According to the Centers for Disease Control and Prevention, in 2016, about 87% of the TB cases reported in the US were among racial and ethnic minorities. The objective of this study is to explore the risks for pregnancy complications and in-hospital death among mothers diagnosed with TB across racial/ethnic groups in the US. This retrospective cohort study utilized National Inpatient Sample data for all inpatient hospital discharges in the US. We analyzed pregnancy-related hospitalizations and births in the US from January 1, 2002 through December 31, 2014 (n = 57,393,459). Multivariable logistic regression was applied to generate odds ratios for the association between TB status and the primary study outcomes (i.e., pregnancy complications and in-hospital death) across racial/ethnic categories. The prevalence of TB was 7.1 per 100,000 pregnancy-related hospitalizations. The overall prevalence of pregnancy complications was 80% greater among TB-infected mothers than their uninfected counterparts. Severe pre-eclampsia, eclampsia, placenta previa, post-partum hemorrhage, sepsis and anemia occurred with greater frequency among mothers with a TB diagnosis than those without TB, irrespective of race/ethnicity. The rate of in-hospital death among TB patients was 37 times greater among TB-infected than in non-TB infected mothers (468.8 per 100,000 versus 12.6 per 100,000). A 3-fold increased risk of in-hospital death was observed among black TB-negative mothers compared to their white counterparts. No racial/ethnic disparities in maternal morbidity or in-hospital death were found among mothers with TB disease. TB continues to be an important cause of morbidity and mortality among pregnant women in the US. Resources to address TB disease should also target pregnant women, especially racial

Cancer is one of the principal causes of death in Malaysia. This study was performed to determine the pattern of rate of cancer deaths at a public hospital in Malaysia over an 11 year period from year 2001 to 2011, to determine the best fitted model of forecasting the rate of cancer deaths using Univariate Modeling and to forecast the rates for the next two years (2012 to 2013). The medical records of the death of patients with cancer admitted at this Hospital over 11 year's period were reviewed, with a total of 663 cases. The cancers were classified according to 10th Revision International Classification of Diseases (ICD-10). Data collected include socio-demographic background of patients such as registration number, age, gender, ethnicity, ward and diagnosis. Data entry and analysis was accomplished using SPSS 19.0 and Minitab 16.0. The five Univariate Models used were Naïve with Trend Model, Average Percent Change Model (ACPM), Single Exponential Smoothing, Double Exponential Smoothing and Holt's Method. The overall 11 years rate of cancer deaths showed that at this hospital, Malay patients have the highest percentage (88.10%) compared to other ethnic groups with males (51.30%) higher than females. Lung and breast cancer have the most number of cancer deaths among gender. About 29.60% of the patients who died due to cancer were aged 61 years old and above. The best Univariate Model used for forecasting the rate of cancer deaths is Single Exponential Smoothing Technique with alpha of 0.10. The forecast for the rate of cancer deaths shows a horizontally or flat value. The forecasted mortality trend remains at 6.84% from January 2012 to December 2013. All the government and private sectors and non-governmental organizations need to highlight issues on cancer especially lung and breast cancers to the public through campaigns using mass media, media electronics, posters and pamphlets in the attempt to decrease the rate of cancer deaths in Malaysia.

AIM: Neonatal deaths (≤28 days) account for more than half of child mortality in Vietnam. Presumably most die in hospital, but data are scarce. This study aimed to identify risk factors of death among hospitalised neonates. METHODS: We prospectively studied all neonatal deaths and expected deaths...... (discharged alive after withdrawal of life-sustaining treatment) in a Vietnamese tertiary paediatric hospital during a 12-month period in 2009-2010. The medical files were audited classifying admission prognosis, discharge outcome, cause of death/expected death according to two classifications, and important...... and potentially avoidable risk factors during the hospital stay. RESULTS: Among 5763 neonates admitted, 235 deaths and 67 expected deaths were included. According to both classifications, major causes were congenital malformations, prematurity and severe infections. Six risk factors were identified in 85% (60...

Full Text Available Background/Aim: Anemia in renal insufficiency results in part from impaired erythrocyte formation due to erythropoietin and iron deficiency. Beyond that, renal insufficiency enhances eryptosis, the suicidal erythrocyte death characterized by phosphatidylserine-exposure at the erythrocyte surface. Eryptosis may be stimulated by increase of cytosolic Ca2+-activity ([Ca2+]i. Several uremic toxins have previously been shown to stimulate eryptosis. Renal insufficiency is further paralleled by increase of plasma phosphate concentration. The present study thus explored the effect of phosphate on erythrocyte death. Methods: Cell volume was estimated from forward scatter, phosphatidylserine-exposure from annexin V binding, and [Ca2+]i from Fluo3-fluorescence. Results: Following a 48 hours incubation, the percentage of phosphatidylserine exposing erythrocytes markedly increased as a function of extracellular phosphate concentration (from 0-5 mM. The exposure to 2 mM or 5 mM phosphate was followed by slight but significant hemolysis. [Ca2+]i did not change significantly up to 2 mM phosphate but significantly decreased at 5 mM phosphate. The effect of 2 mM phosphate on phosphatidylserine exposure was significantly augmented by increase of extracellular Ca2+ to 1.7 mM, and significantly blunted by nominal absence of extracellular Ca2+, by additional presence of pyrophosphate as well as by presence of p38 inhibitor SB203580. Conclusion: Increasing phosphate concentration stimulates erythrocyte membrane scrambling, an effect depending on extracellular but not intracellular Ca2+ concentration. It is hypothesized that suicidal erythrocyte death is triggered by complexed CaHPO4.

Full Text Available Predictors of death in hospitalized HIV-infected patients have not been previously reported in Bangladesh.The primary aim of this study was to determine predictors of death among hospitalized HIV-infected patients at a large urban hospital in Bangladesh.A study was conducted in the HIV in-patient unit (Jagori Ward of icddr,b's Dhaka Hospital. Characteristics of patients who died during hospitalization were compared to those of patients discharged from the ward. Bivariate analysis was performed to determine associations between potential risk factors and death. Multivariable logistic regression was used to identify factors independently associated with death.Of 293 patients admitted to the Jagori Ward, 57 died during hospitalization. Most hospitalized patients (67% were male and the median age was 35 (interquartile range: 2-65 years. Overall, 153 (52% patients were diagnosed with HIV within 6 months of hospitalization. The most common presumptive opportunistic infections (OIs identified were tuberculosis (32%, oesophageal candidiasis (9%, Pneumocystis jirovecii pneumonia (PJP (8%, and histoplasmosis (7%. On multivariable analysis, independent predictors of mortality were CD4 count ≤200 cells/mm3 (adjusted odds ratio [aOR]: 16.6, 95% confidence interval [CI]: 3.7-74.4, PJP (aOR: 18.5, 95% CI: 4.68-73.3, oesophageal candidiasis (aOR: 27.5, 95% CI: 5.5-136.9, malignancy (aOR:15.2, 95% CI: 2.3-99.4, and bacteriuria (aOR:7.9, 95% CI: 1.2-50.5. Being on antiretroviral therapy prior to hospitalization (aOR: 0.2, 95% CI: 0.06-0.5 was associated with decreased mortality.This study showed that most patients who died during hospitalization on the Jagori Ward had HIV-related illnesses which could have been averted with earlier diagnosis of HIV and proper management of OIs. It is prudent to develop a national HIV screening programme to facilitate early identification of HIV.

Full Text Available An aging population and epidemiological transition involves prolonged terminal illnesses and an increased demand for end-stage support in health services, mainly in hospitals. Changes in health care and government health policies may influence the death locations, making it possible to remain at home or in an institution. The scope of this article is to analyze death locations in the city of Londrina, State of Paraná, from 1996 to 2010, and to verify the influence of population and health policy changes on these statistics. An analysis was conducted into death locations in Londrina in Mortality Information System (SIM considering the main causes and locations of death. There was an increase of 28% in deaths among the population in general, though 48% for the population over 60 years of age. There was an increase of deaths in hospitals, which were responsible for 70% of the occurrences, though death frequencies in others locations did not increase, and deaths in the home remained at about 18%. The locations of death did not change during this period, even with health policies that broadened care in other locations, such as the patient´s home. The predominance of hospital deaths was similar to other Brazilian cities, albeit higher than in other countries.

New Zealand lacks a comprehensive national profile of home injuries, this information is necessary to develop effective targeted injury prevention initiatives. This study describes the epidemiology of unintentional home injuries resulting in death or admission to hospital among young and middle-age New Zealanders. Cases were selected from Ministry of Health public hospital discharge (2000-2009) and mortality data (1998-2007), and included all 20-64 year olds where the place of injury occurrence was classified as 'home'. Only initial hospitalisations with a stay of 24 hours or longer were included. The circumstances of injury were coded according to the ICD-10 external cause categories. Mean annual rates of death or hospitalisation were calculated using census and intercensal denominator data. On average 4000 young and middle-age adults are admitted to hospital and 60 die annually as a result of unintentional injuries sustained at home. Overall, mortality rates were highest amongst males, older adults (50 to 64 years), and Māori. The leading causes of unintentional home injury deaths were poisoning, falls, and burns. Hospitalisation rates were highest among males, the older age groups (> 40 years), and Maori. As age increased so did the incidence of hospital admission. The leading contributors resulting in admission to hospital were falls, cutting or piercing, overexertion, and poisoning. Injuries due to falls had the highest median length of hospital stay and in-hospital mortality rate. As deprivation increased so did the frequency of hospital admissions due to fall and cutting or piercing injuries. Poisonings and falls are the leading causes of unintentional home injury death among young and middle-aged New Zealanders. In addition, falls are a significant contributor to home injury resulting in admission to hospital. The large numbers of home injuries occurring each year in New Zealand, mean that even moderately successful injury prevention interventions could

Accurate and timely information on the causes of child deaths is essential in guiding efforts to improve child survival, by providing data from which health profiles can be constructed and relevant health policies formulated. The purpose of this study was to identify causes of death in children younger than 5 years-old in a tertiary hospital in South Africa. Death certificates from the Pietersburg/Mankweng hospital complex, for the period of January 1, 2008 through December 31, 2010, were obtained for all patients younger than 5 years and were retrospectively reviewed. Data were collected using a data collection form designed for the study. Information abstracted included: date of death, age, sex, and cause of death. A total of 1266 deaths were recorded, the sex ratio was 1.26 boys per girl. About 611 (48%) of deaths were listed as neonatal deaths (0-28 days), 387 (31%) were listed as infant deaths (29 days-11 months), and 268 (21%) as children's death (1-4 years). For neonates the leading causes of death were: prematurity/low birth weight, birth asphyxia and pneumonia. For the infant death group, the leading causes of death were pneumonia, diarrhea, and HIV/AIDS; and in the children's group, the leading causes were injuries, diarrhea and pneumonia. There was no statistical significant difference in the proportions of causes of death based on the sex of children. The top 10 leading causes of death in children under-5 years old treated at Pietersburg/Mankweng Hospital Complex were in descending order: prematurity/low birth weight, pneumonia, diarrheal diseases, birth asphyxia, and severe malnutrition, HIV/AIDS, hydrocephalus, unintentional injuries, meningitis and other infections. These ten conditions represent 73.9% of causes of death at this facility. A mix of multi-faceted interventions is needed to address these causes of death in children.

This study evaluated preoperative predictors of in-hospital death for the surgical treatment of patients with acute type A aortic dissection (Type A) and created an easy-to-use scorecard to predict in-hospital death. We reviewed retrospectively all consecutive patients who underwent operations for acute Type A between 1996 and 2011 at 2 tertiary care institutions. A logistic regression model was created to identify independent preoperative predictors of in-hospital death. The results were used to create a scorecard predicting operative risk. Emergency operations were performed in 534 consecutive patients for acute Type A. Mean age was 61 ± 14 years and 36.3% were women. Critical preoperative state was present in 31% of patients and malperfusion of one or more end organs in 36%. Unadjusted in-hospital mortality was 18.7% and not significantly different between institutions. Independent predictors of in-hospital death were age 50 to 70 years (odds ratio [OR], 3.8; p = 0.001), age older than 70 years (OR, 2.8; p = 0.03), critical preoperative state (OR, 3.2; p risk score based on these variables. The patients were stratified into four risk categories predicting in-hospital death: less than 10%, 10% to 25%, 25% to 50%, and more than 50%. This represents one of the largest series of patients with Type A in which a risk model was created. Using our approach, we have shown that age, critical preoperative state, and malperfusion syndrome were strong independent risk factors for early death and could be used for the preoperative risk assessment.

Full Text Available Abstract Background Several suicide and suicidal behaviour risk factors are highly prevalent in asylum seekers, but there is little insight into the suicide death rate and the suicidal behaviour incidence in this population. The main objective of this study is to assess the burden of suicide and hospital-treated non-fatal suicidal behaviour in asylum seekers in the Netherlands and to identify factors that could guide prevention. Methods We obtained data on cases of suicide and suicidal behaviour from all asylum seeker reception centres in the Netherlands (period 2002-2007, age 15+. The suicide death rates in this population and in subgroups by sex, age and region of origin were compared with the rate in the Dutch population; the rates of hospital-treated suicidal behaviour were compared with that in the population of The Hague using indirect age group standardization. Results The study included 35 suicide deaths and 290 cases of hospital-treated suicidal behaviour. The suicide death rate and the incidence of hospital-treated suicidal behaviour differed between subgroups by sex and region of origin. For male asylum seekers, the suicide death rate was higher than that of the Dutch population (N = 32; RR = 2.0, 95%CI 1.37-2.83. No difference was found between suicide mortality in female asylum seekers and in the female general population of the Netherlands (N = 3; RR = 0.73; 95%CI 0.15-2.07. The incidence of hospital-treated suicidal behaviour was high in comparison with the population of The Hague for males and females from Europe and the Middle East/South West Asia, and low for males and females from Africa. Health professionals knew about mental health problems prior to the suicidal behaviour for 80% of the hospital-treated suicidal behaviour cases in asylum seekers. Conclusions In this study the suicide death rate was higher in male asylum seekers than in males in the reference population. The incidence of hospital-treated suicidal behaviour

To study long-term mortality and causes of death in a cohort of drug users in relation to main type of drug use and HIV-status. A total of 1640 hospitalized drug users in Stockholm was followed up from 1985 to the end of 2007. The mortality was compared with the general Swedish population and hazard ratios (HR) for the main risk indicators were calculated. The causes of death were studied, using information from death certificates. 630 persons died during the observation period. The Standard Mortality Ratio (SMR) was 16.1 (males 13.8, females 18.5). The crude mortality rate was 2.0 % (males 2.2% and females 1.5%). The mortality rate was higher in heroin users than among amphetamine users, HR 1.96, controlled for age and other risk factors. The mortality rate among individuals infected with the human immunodeficiency virus (HIV) was high (4.9 %), HR 2.64, compared with HIV-negative individuals. Most of the deaths were from other causes than acquired immune deficiency syndrome. One-third of deaths (227) were caused by heroin intoxication. The number of deaths from HIV-related causes decreased after 1996, when highly active anti-retroviral therapy was introduced. In all, there were 92 HIV-related deaths. Deaths from natural causes increased during the observation period. The SMR was highest for cardiovascular and gastrointestinal diseases. The results indicate a correlation between amphetamine use and death from cerebral haemorrhage. A high proportion of natural deaths were alcohol-related. The death rate among illicit drug users was persistently high. Alcohol consumption was a contributing factor to premature death. © 2014 the Nordic Societies of Public Health.

Current prognostic models factor in patient and disease specific variables but do not consider cumulative risks of hospitalization over time. We developed risk models of the likelihood of death associated with cumulative exposure to hospitalization, based on time-varying risks of hospitalization over any given day, as well as day of the week. Model performance was evaluated alone, and in combination with simple disease-specific models. Patients admitted between 2000 and 2006 from 501 public and private hospitals in NSW, Australia were used for training and 2007 data for evaluation. The impact of hospital care delivered over different days of the week and or times of the day was modeled by separating hospitalization risk into 21 separate time periods (morning, day, night across the days of the week). Three models were developed to predict death up to 7-days post-discharge: 1/a simple background risk model using age, gender; 2/a time-varying risk model for exposure to hospitalization (admission time, days in hospital); 3/disease specific models (Charlson co-morbidity index, DRG). Combining these three generated a full model. Models were evaluated by accuracy, AUC, Akaike and Bayesian information criteria. There was a clear diurnal rhythm to hospital mortality in the data set, peaking in the evening, as well as the well-known 'weekend-effect' where mortality peaks with weekend admissions. Individual models had modest performance on the test data set (AUC 0.71, 0.79 and 0.79 respectively). The combined model which included time-varying risk however yielded an average AUC of 0.92. This model performed best for stays up to 7-days (93% of admissions), peaking at days 3 to 5 (AUC 0.94). Risks of hospitalization vary not just with the day of the week but also time of the day, and can be used to make predictions about the cumulative risk of death associated with an individual's hospitalization. Combining disease specific models with such time varying- estimates appears to

Caffeine is the most widely consumed psychoactive compound worldwide. It is mostly found in coffee, tea, energizing drinks and in some drugs. However, it has become really easy to obtain pure caffeine (powder or tablets) on the Internet markets. Mechanisms of action are dose-dependent. Serious toxicities such as seizure and cardiac arrhythmias, seen with caffeine plasma concentrations of 15 mg/L or higher, have caused poisoning or, rarely, death; otherwise concentrations of 3⁻6 mg/kg are considered safe. Caffeine concentrations of 80⁻100 mg/L are considered lethal. The aim of this systematic review, performed following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement for the identification and selection of studies, is to review fatal cases in which caffeine has been recognized as the only cause of death in order to identify potential categories at risk. A total of 92 cases have been identified. These events happened more frequently in infants, psychiatric patients, and athletes. Although caffeine intoxication is relatively uncommon, raising awareness about its lethal consequences could be useful for both clinicians and pathologists to identify possible unrecognized cases and prevent related severe health conditions and deaths.

Genome-Wide Association Study of Serum Selenium Concentrations

Full Text Available Selenium is an essential trace element and circulating selenium concentrations have been associated with a wide range of diseases. Candidate gene studies suggest that circulating selenium concentrations may be impacted by genetic variation; however, no study has comprehensively investigated this hypothesis. Therefore, we conducted a two-stage genome-wide association study to identify genetic variants associated with serum selenium concentrations in 1203 European descents from two cohorts: the Prostate, Lung, Colorectal, and Ovarian (PLCO Cancer Screening and the Women’s Health Initiative (WHI. We tested association between 2,474,333 single nucleotide polymorphisms (SNPs and serum selenium concentrations using linear regression models. In the first stage (PLCO 41 SNPs clustered in 15 regions had p < 1 × 10−5. None of these 41 SNPs reached the significant threshold (p = 0.05/15 regions = 0.003 in the second stage (WHI. Three SNPs had p < 0.05 in the second stage (rs1395479 and rs1506807 in 4q34.3/AGA-NEIL3; and rs891684 in 17q24.3/SLC39A11 and had p between 2.62 × 10−7 and 4.04 × 10−7 in the combined analysis (PLCO + WHI. Additional studies are needed to replicate these findings. Identification of genetic variation that impacts selenium concentrations may contribute to a better understanding of which genes regulate circulating selenium concentrations.

Death certificates underestimate infections as proximal causes of death in the U.S.

Full Text Available Death certificates are a primary data source for assessing the population burden of diseases; however, there are concerns regarding their accuracy. Diagnosis-Related Group (DRG coding of a terminal hospitalization may provide an alternative view. We analyzed the rate and patterns of disagreement between death certificate data and hospital claims for patients who died during an inpatient hospitalization.We studied respondents from the Health and Retirement Study (a nationally representative sample of older Americans who had an inpatient death documented in the linked Medicare claims from 1993-2007. Causes of death abstracted from death certificates were aggregated to the standard National Center for Health Statistics List of 50 Rankable Causes of Death. Centers for Medicare and Medicaid Services (CMS-DRGs were manually aggregated into a parallel classification. We then compared the two systems via 2×2, focusing on concordance. Our primary analysis was agreement between the two data sources, assessed with percentages and Cohen's kappa statistic.2074 inpatient deaths were included in our analysis. 36.6% of death certificate cause-of-death codes agreed with the reason for the terminal hospitalization in the Medicare claims at the broad category level; when re-classifying DRGs without clear alignment as agreements, the concordance only increased to 61%. Overall Kappa was 0.21, or "fair." Death certificates in this cohort redemonstrated the conventional top 3 causes of death as diseases of the heart, malignancy, and cerebrovascular disease. However, hospitalization claims data showed infections, diseases of the heart, and cerebrovascular disease as the most common diagnoses for the same terminal hospitalizations.There are significant differences between Medicare claims and death certificate data in assigning cause of death for inpatients. The importance of infections as proximal causes of death is underestimated by current death certificate

The shift from an industrial to a service-based economy has seen a decline in work-related injuries (WRIs) and mortality. How this relates to migrant workers, who traditionally held high-risk jobs is unknown. This study examined deaths and hospital admissions from WRI, among foreign and Australian-born workers. Tabulated population data from the 1991 to 2011 censuses, national deaths 1991-2002 and hospital admission for 2001-10. Direct age standardised mortality and hospital admission rates (DSRs) and rate ratios (RRs) were derived to examine differences in work-related mortality/hospital admissions by gender, country of birth, employment skill level and years of residence in Australia. DSRs and RRs were generally lower or no different between Australian and foreign-born workers. Among men, mortality DSRs were lower for nine of 16 country of birth groups, and hospital admissions DSRs for 14 groups. An exception was New Zealand-born men, with 9% (95%CI 9-13) excess mortality and 24% (95%CI 22-26) excess hospital admissions. Four decades ago, foreign-born workers were generally at higher risk of WRI than Australian-born. This pattern has reversed. The local-born comprise 75% of the population and a pro-active approach to health and safety regulation could achieve large benefits. © 2015 Public Health Association of Australia.

Full Text Available Abstract Background Although the attitude among doctors toward disclosing a cancer diagnosis is becoming more positive, informing patients of their disease has not yet become a common practice in Japan. We examined the psychological process, from hospitalization until death, among uninformed terminal cancer patients in Japan, and developed a psychological model. Methods Terminal cancer patients hospitalized during the recruiting period voluntarily participated in in-depth interviews. The data were analyzed by grounded theory. Results Of the 87 uninformed participants at the time of hospitalization, 67% (N = 59 died without being informed of their diagnosis. All were male, 51–66 years of age, and all experienced five psychological stages: anxiety and puzzlement, suspicion and denial, certainty, preparation, and acceptance. At the end of each stage, obvious and severe feelings were observed, which were called "gates." During the final acceptance stage, patients spent a peaceful time with family, even talking about their dreams with family members. Conclusion Unlike in other studies, the uninformed patients in this study accepted death peacefully, with no exceptional cases. Despite several limitations, this study showed that almost 70% of the uninformed terminal cancer patients at hospitalization died without being informed, suggesting an urgent need for culturally specific and effective terminal care services for cancer patients in Japan.

Studies aiming to identify palliative care populations have used data from death certificates and in some cases hospital records. The size and characteristics of the identified populations can show considerable variation depending on the data sources used. It is important that service planners and researchers are aware of this. To illustrate the differences in the size and characteristics of a potential palliative care population depending on the differential use of linked hospital records and death certificate data. Retrospective cohort study. The cohort consisted of 23,852 people aged 20 years and over who died in Western Australia between 1 January 2009 and 31 December 2010 after excluding deaths related to pregnancy or trauma. Within this cohort, the number, proportion and characteristics of people who died from one or more of 10 medical conditions considered amenable to palliative care were identified using linked hospital records and death certificate data. Depending on the information source(s) used, between 43% and 73% of the 23,852 people who died had a condition potentially amenable to palliative care identified. The median age at death and the sex distribution of the decedents by condition also varied with the information source. Health service planners and researchers need to be aware of the limitations when using hospital records and death certificate data to determine a potential palliative care population. The use of Emergency Department and other administrative data sources could further exacerbate this variation.

Sudden death in eating disorders

Full Text Available Beatriz Jáuregui-Garrido1, Ignacio Jáuregui-Lobera2,31Department of Cardiology, University Hospital Virgen del Rocío, 2Behavioral Sciences Institute, 3Pablo de Olavide University, Seville, SpainAbstract: Eating disorders are usually associated with an increased risk of premature death with a wide range of rates and causes of mortality. “Sudden death” has been defined as the abrupt and unexpected occurrence of fatality for which no satisfactory explanation of the cause can be ascertained. In many cases of sudden death, autopsies do not clarify the main cause. Cardiovascular complications are usually involved in these deaths. The purpose of this review was to report an update of the existing literature data on the main findings with respect to sudden death in eating disorders by means of a search conducted in PubMed. The most relevant conclusion of this review seems to be that the main causes of sudden death in eating disorders are those related to cardiovascular complications. The predictive value of the increased QT interval dispersion as a marker of sudden acute ventricular arrhythmia and death has been demonstrated. Eating disorder patients with severe cardiovascular symptoms should be hospitalized. In general, with respect to sudden death in eating disorders, some findings (eg, long-term eating disorders, chronic hypokalemia, chronically low plasma albumin, and QT intervals >600 milliseconds must be taken into account, and it must be highlighted that during refeeding, the adverse effects of hypophosphatemia include cardiac failure. Monitoring vital signs and performing electrocardiograms and serial measurements of plasma potassium are relevant during the treatment of eating disorder patients.Keywords: sudden death, cardiovascular complications, refeeding syndrome, QT interval, hypokalemia

Neonatal deaths (≤28 days) account for more than half of child mortality in Vietnam. Presumably most die in hospital, but data are scarce. This study aimed to identify risk factors of death among hospitalised neonates. We prospectively studied all neonatal deaths and expected deaths (discharged alive after withdrawal of life-sustaining treatment) in a Vietnamese tertiary paediatric hospital during a 12-month period in 2009-2010. The medical files were audited classifying admission prognosis, discharge outcome, cause of death/expected death according to two classifications, and important and potentially avoidable risk factors during the hospital stay. Among 5763 neonates admitted, 235 deaths and 67 expected deaths were included. According to both classifications, major causes were congenital malformations, prematurity and severe infections. Six risk factors were identified in 85% (60/71) of the neonates with a relatively good prognosis: recognition or response to danger signs, internal transfers, nosocomial infections, sepsis management, access to usual equipment/staff, and family perception. Among 302 neonatal deaths/expected deaths, the major causes were congenital malformations, prematurity and severe infections. Six important and potentially avoidable risk factors could be addressed in the subgroup with relatively good admission prognosis, without implementing new technology or major organisational changes. ©2013 Foundation Acta Paediatrica.

Homebound adults experience significant symptom burden. To examine demographic and clinical characteristics associated with high symptom burden in the homebound, and to examine associations between symptom burden and time to hospitalization, nursing home placement, and death. Three hundred eighteen patients newly enrolled in the Mount Sinai Visiting Doctors Program, an urban home-based primary care program, were studied. Patient sociodemographic characteristics, symptom burden (measured via the Edmonton Symptom Assessment Scale), and incidents of hospitalization, nursing home placement, and death were collected via medical chart review. Multivariate Cox proportional hazards models were used to analyze the effect of high symptom burden on time to first hospitalization, nursing home placement, and death. Of the study sample, 45% had severe symptom burden (i.e., Edmonton Symptom Assessment Scale score >6 on at least one symptom). Patients with severe symptom burden were younger (82.0 vs. 85.5 years, P nursing home placement or death. The homebound with severe symptom burden represents a unique cohort of patients who are at increased risk of hospitalization. Tailored symptom management via home-based primary and palliative care programs may prevent unnecessary health care utilization in this population.

Full Text Available Pulmonary embolism continues to be a significant cause of death. The aim was to derive and validate a risk prediction model for in-hospital death after acute pulmonary embolism to identify low risk patients suitable for outpatient management.A confirmed acute pulmonary embolism database of 1,426 consecutive patients admitted to a tertiary-center (2000-2012 was analyzed, with odd and even years as derivation and validation cohorts respectively. Risk stratification for in-hospital death was performed using multivariable logistic-regression modelling. Models were compared using receiver-operating characteristic-curve and decision curve analyses.In-hospital mortality was 3.6% in the derivation cohort (n = 693. Adding day-1 sodium and bicarbonate to simplified Pulmonary Embolism Severity Index (sPESI significantly increased the C-statistic for predicting in-hospital death (0.71 to 0.86, P = 0.001. The validation cohort yielded similar results (n = 733, C-statistic 0.85. The new model was associated with a net reclassification improvement of 0.613, and an integrated discrimination improvement of 0.067. The new model also increased the C-statistic for predicting 30-day mortality compared to sPESI alone (0.74 to 0.83, P = 0.002. Decision curve analysis demonstrated superior clinical benefit with the use of the new model to guide admission for pulmonary embolism, resulting in 43 fewer admissions per 100 presentations based on a risk threshold for admission of 2%.A risk model incorporating sodium, bicarbonate, and the sPESI provides accurate risk prediction of acute in-hospital mortality after pulmonary embolism. Our novel model identifies patients with pulmonary embolism who are at low risk and who may be suitable for outpatient management.

Current management principles of haemorrhagic shock after trauma emphasize earlier transfusion therapy to prevent dilution of clotting factors and correct coagulopathy. London's air ambulance (LAA) was the first UK civilian pre-hospital service to routinely offer pre-hospital red blood cell (RBC) transfusion (phRTx). We investigated the effect of phRTx on mortality. Retrospective trauma database study comparing mortality before-implementation with after-implementation of phRTx in exsanguinating trauma patients. Univariate logistic regression was performed for the unadjusted association between phRTx and mortality was performed, and multiple logistic regression adjusting for potential confounders. We identified 623 subjects with suspected major haemorrhage. We excluded 84 (13.5%) patients due to missing data on survival status. Overall 187 (62.3%) patients died in the before phRTx period and 143 (59.8%) died in the after phRTx group. There was no significant improvement in overall survival after the introduction of phRTx (p = 0.554). Examination of pre-hospital mortality demonstrated 126 deaths in the pre-phRTx group (42.2%) and 66 deaths in the RBC administered group (27.6%) There was a significant reduction in pre-hospital mortality in the group who received RBC (p < 0.001). phRTx was associated with increased survival to hospital, but not overall survival. The "delay death" effect of phRTx carries an impetus to further develop in-hospital strategies to improve survival in severely bleeding patients.

To describe health care utilization (HCU) at the end of life in cancer patients. These data are relevant to plan palliative care services, and to develop training programs for involved health care professionals. The Dutch Bone Metastasis Study (DBMS) was a nationwide study proving equal effectiveness of single fraction palliative radiotherapy compared with multiple fractions for painful bone metastases in 1157 patients. The 860 (74%) patients who died during follow-up were included in the current analysis. The main outcome was the frequency of hospital-based (outpatient contact or admission) and/or general practitioner (GP) contact during the last 12 weeks of life. Changes in HCU towards death were related to data on quality of life and pain intensity using a multilevel regression model. Hospital-based HCU was reported in 1801 (63%) returned questionnaires, whereas GP contact was stated in 1246 (43%). In 573 (20%) questionnaires, both types of HCU were reported. In multilevel regression analyses, the frequency of outpatient contacts remained constant during the weeks towards death, whereas the frequency of GP contacts increased. Lower valuation of quality of life was related to both GP- and hospital-based HCU. There was a high consumption of hospital-based HCU in the last 12 weeks of life of cancer patients with bone metastases. Hospital-based HCU did not decrease during the weeks towards death, despite an increase in GP contacts. Future planning of palliative care and training programs should encompass close collaboration between medical specialists and GPs to optimize end-of-life care.

The objective of this study was to evaluate the underlying causes of neonatal mortality (NNM) in midwife-attended home births and compare them to hospital births attended by a midwife or a physician in the United States (US). A retrospective cohort study of the Centers for Disease Control (CDC) linked birth/infant death data set (linked files) for 2008 through 2012 of singleton, term (≥37 weeks) births and normal newborn weights (≥2500 grams). Midwife-attended home births had the highest rate of neonatal deaths [122/95,657 neonatal mortality (NNM) 12.75/10,000; relative risk (RR): 3.6, 95% confidence interval (CI) 3-4.4], followed by hospital physician births (8695/14,447,355 NNM 6.02/10,000; RR: 1.7 95% CI 1.6-1.9) and hospital midwife births (480/1,363,199 NNM 3.52/10,000 RR: 1). Among midwife-assisted home births, underlying causes attributed to labor and delivery caused 39.3% (48/122) of neonatal deaths (RR: 13.4; 95% CI 9-19.9) followed by 29.5% due to congenital anomalies (RR: 2.5; 95% CI 1.8-3.6), and 12.3% due to infections (RR: 4.5; 95% CI 2.5-8.1). There are significantly increased risks of neonatal deaths among midwife-attended home births associated with three underlying causes: labor and delivery issues, infections, and fetal malformations. This analysis of the causes of neonatal death in planned home birth shows that it is consistently riskier for newborns to deliver at home than at the hospital. Physicians, midwives, and other health care providers have a professional responsibility to share information about the clinical benefits and risks of clinical management.

Despite emerging data of cost savings under palliative care in various regions, no such data have been generated in response to the high burden of terminal illness in Africa. This evaluation of a novel hospital-based palliative care service for patients with advanced organ failure in urban South Africa aimed to determine whether the service reduces admissions and increases home death rates compared with the same fixed time period of standard hospital care. Data on admissions and place of death were extracted from routine hospital activity records for a fixed period before death, using standard patient daily expense rates. Data from the first 56 consecutive deaths under the new service (intervention group) were compared with 48 consecutive deaths among patients immediately before the new service (historical controls). Among the intervention and control patients, 40 of 56 (71.4%) and 47 of 48 (97.9%), respectively, had at least one admission (P home death was achieved by 33 of 56 (58.9%) and nine of 48 (18.8%), respectively (P ≤ 0.001). These data demonstrate that an outpatient hospital-based service reduced admissions and improved the rate of home deaths and offers a feasible and cost-effective model for such settings.

It is recognized that socioeconomic status (SES) has a significant impact on health and wellbeing; however, the effect of SES on suicide is contested. This study explored the effect of SES in suicide deaths and decomposed inequality into its determinants to calculate relative contributions. Through a cross-sectional study, 546 suicide deaths and 6,818 suicide attempts from January 1, 2010 to December 31, 2014 in Ilam Province, Western Iran were explored. Inequality was measured by the absolute concentration index (ACI) and decomposed contributions were identified. All analyses were performed using STATA ver. 11.2 (Stata Corp., College Station, TX, USA). The overall ACI for suicide deaths was -0.352 (95% confidence interval, -0.389 to -0.301). According to the results, 9.8% of socioeconomic inequality in suicide deaths was due to addiction in attempters. ACI ranged from -0.34 to -0.03 in 2010-2014, showing that inequality in suicide deaths declined over time. Findings showed suicide deaths were distributed among the study population unequally, and our results confirmed a gap between advantaged and disadvantaged attempters in terms of death. Socioeconomic inequalities in suicide deaths tended to diminish over time, as suicide attempts progressed in Ilam Province.

To examine the influence of nursing-specifically nurse staffing and the nurse work environment-on quality of care and patient satisfaction in hospitals with varying concentrations of Black patients. Cross-sectional secondary analysis of 2006-2007 nurse survey data collected across four states (Florida, Pennsylvania, New Jersey, and California), the Hospital Consumer Assessment of Healthcare Providers and Systems survey, and administrative data. Global analysis of variance and linear regression models were used to examine the association between the concentration of Black patients on quality measures (readiness for discharge, patient or family complaints, health care-associated infections) and patient satisfaction, before and after accounting for nursing and hospital characteristics. Nurses working in hospitals with higher concentrations of Blacks reported poorer confidence in patients' readiness for discharge and more frequent complaints and infections. Patients treated in hospitals with higher concentrations of Blacks were less satisfied with their care. In the fully adjusted regression models for quality and patient satisfaction outcomes, the effects associated with the concentration of Blacks were explained in part by nursing and structural hospital characteristics. This study demonstrates a relationship between nursing, structural hospital characteristics, quality of care, and patient satisfaction in hospitals with high concentrations of Black patients. Consideration of nursing factors, in addition to other important hospital characteristics, is critical to understanding and improving quality of care and patient satisfaction in minority-serving hospitals. © 2011 Sigma Theta Tau International.

Analysis of the underlying causes of death can develop action plans for prevention of death that could be avoided. The aim of our study was to analyse the causes of cardiovascular deaths in the cardiology department of Yalgado Ouedraogo University Hospital. The study was a descriptive retrospective study over a 24 month period among patients who died in the department. Prevalence of death in the cardiology department was of 13.2%. Sex ratio was of 1.2 and 72.7% of patients were residing in Ouagadougou. Mean age of patients was 56.1 years and 59.4% of patients were under 65 years old. Hypertension was the major cardiovascular risk factor (46.1%) and 27.4% of patients had a medical history of dilated cardiomyopathy. Cardiogenic shock was the immediate cause of death in 55.5% of cases and the initial cause of death was hypertension and its complications in 46.1% of cases. Death was not notified in 18% of cases and no death had been medically certified. Death statistics are the most reliable data for public health interventions. However, it is necessary to establish an effective method of data gathering according to the WHO standards in order to facilitate international comparison.

Objective: To investigate the value of bedside echocardiography in diagnosis and risk assessment of in-hospital death of patients with Stanford type A aortic dissection. Methods: The clinical data of 229 patients with Stanford type A aortic dissection diagnosed by CT angiography in Zhongshan Hospital affiliated to Fudan University between January 2009 and January 2016 were retrospectively analyzed. The patients were divided into survival group(191 cases)and non-survival group(38 cases)according to presence or absence of in-hospital death. The bedside echocardiography features were analyzed, and influence factors of in-hospital death were determined by multivariate logistic regression analysis. Results: (1) Compared with the survival group, the non-survival group had lower surgery rate (60.52%(23/38) vs. 85.34%(163/191), P 0.05). (2) The bedside echocardiography results showed that prevalence of aortic valve involvement(65.79%(25/38) vs.34.03%(65/191), P 0.05). (3) The multivariate logistic regression analysis showed that aortic valve involvement( OR =3.275, 95% CI 1.290-8.313, P risk factors for in-hospital death in patients with Stanford type A aortic dissection. Conclusions: Bedside echocardiography has significant diagnostic value for Stanford type A aortic dissection. Aortic valve involvement, enlargement of aortic root diameter and without surgery are independent risk factors for patients with Stanford type A aortic dissection.

Background The loss of a child is considered one of the most stressful events in the life of a parent. We hypothesized that parental bereavement increases the risk of hospital admission for a psychiatric disorder, especially for affective disorders. Methods We studied a cohort of 1,082,503 persons...... identified from national registers in Denmark who were born between 1952 and 1999 and had at least one child under 18 years of age during the follow-up period, from 1970 to 1999. Parents who lost a child during follow-up were categorized as “bereaved” from the date of death of the child. Results As compared...... with parents who did not lose a child, parents who lost a child had an overall relative risk of a first psychiatric hospitalization for any disorder of 1.67 (95 percent confidence interval, 1.53 to 1.83). Bereaved mothers had a higher relative risk of being hospitalized for any psychiatric disorder than...

Full Text Available To increase quality of care for critically ill patients admitted to hospitals, understanding various causes of death could provide better quality of care. In this study, medical records of 5360 deceased patientswere reviewed with reference to the mortality reports.A total of 2019 deceased females and 3341deceased males were studied from 2011 to 2013. Neurologic disorders could be categorized as the highest cause of mortality report (25%. Pulmonary, gastrointestinal and heart diseases could be expressed as 17%, 17% and 15% of death episodes respectively. Stroke caused mortality among neurologic disorders in 35% at the minimum age of 27 and maximum age of 94 years old. To prevent worse outcome in critically ill patients admitted to hospital, quality of care related to neurological, pulmonary, heart and gastrointestinal disorders was suggested to be upgrading. To avoid financial burden to the family of deceased related to population that stayed more than a month in hospital, further study is recommended in advance.

Full Text Available In this prospective case series study, we consider the different factors between death and survival groups of organophosphate poisoning. Patients in tertiary-care medical center who had been exposed to organophosphate were included in the study. Pralidoxime (PAM was discontinued after atropine had controlled the clinical situation. We recorded the demographic data, amount of organophosphate consumption, duration of coma, duration of ventilator use, duration of hospitalization, findings of chest X-ray, white blood cell count, acetylcholinesterase concentration, plasma cholinesterase concentration, total atropine amount, duration of atropine use, total PAM amount, duration of PAM use, urine organophosphate peak concentration, duration of urine organophosphate and mortality rate. Urine was collected every 8 hours and was analyzed by gas chromatography equipped with a flame photometric detector and gas chromatography with mass spectrometer detector for organophosphate determination. The urine organophosphate peak concentration was recorded. Wilcoxon rank sum test was used to compare the factors between death and survival groups. Fisher's exact test was used to compare the different findings of chest X-ray between the death and survival groups. Evidently, the death group had a higher amount of organophosphate consumption, duration of coma, and higher white blood cell count than those in the survival group. Also, the death group had lower duration of hospitalization, and decreased concentrations of acetylcholinesterase and plasma cholinesterase. Total PAM amount use and duration of PAM use were lower. However, the duration of ventilator use, findings of chest X-ray, total atropine amount, duration of atropine, urine organophosphate peak concentration and duration of urine organophosphate were similar in both groups. The mortality rate of our 50 cases was 20%. As stated earlier, the cases of the death group had insufficient PAM therapy. The maximum

To examine the association between hospital market concentration and pricing. Hospitals have been merging into systems that potentially wield bargaining power over private health insurers. Concern is growing among policy makers that these systems may respond to provisions of the 2010 health reform legislation by further increasing consolidation and prices. Multivariate statistical methods were used to evaluate the association between hospital market concentration, prices, and profits (contribution margins) for commercially insured patients admitted for any of 6 major cardiac and orthopedic surgery procedures, adjusting for characteristics of the patient (diagnoses, comorbidities,complications) and of the hospital (size, patient volume, teaching status). Data were obtained on 11,330 patients treated in 61 hospitals in 27 markets across 8 states in 2008. Hospital prices for patients in concentrated markets were higher than hospital prices for otherwise-comparable patients in competitive markets by 25.1% for coronary angioplasty, 13.0%for cardiac rhythm management (CRM) device insertion, 19.2% for total knee replacement, 24.1%for total hip replacement, 19.3% for lumbar spine fusion, and 22.7% for cervical spine fusion (P markets by $5259 for angioplasty, $3417 for CRM device insertion, $4123 for total knee replacement, $5889 for total hip replacement, $7931 for lumbar spine fusion, and $4663 for cervical spine fusion (P markets charge significantly higher prices and earn significantly higher margins from private insurers than do hospitals in competitive markets.

Trade-offs involved with market competition, overall costs to payers and consumers, and quality of care have not been well defined. Less competition within any given market may enable provider-driven increases in charges. To examine the association between regional hospital market concentration and hospital charges for hepatopancreaticobiliary surgical procedures. This study included all patients undergoing hepatic or pancreatic resection in the Nationwide Inpatient Sample from January 1, 2003, through December 31, 2011. Hospital market concentration was assessed using a variable-radius Herfindahl-Hirschman Index (HHI) in the 2003, 2006, and 2009 Hospital Market Structure files. Data were analyzed from November 19, 2016, through March 2, 2017. Hepatic or pancreatic resection. Multivariable mixed-effects log-linear models were constructed to determine the association between HHI and total costs and charges for hepatic or pancreatic resection. Weighted totals of 38 711 patients undergoing pancreatic resection (50.8% men and 49.2% women; median age, 65 years [interquartile range, 55-73 years]) and 52 284 patients undergoing hepatic resection (46.8% men and 53.2% women; median age, 59 years [interquartile range, 49-69 years]) were identified. Higher institutional volume was associated with lower cost of pancreatic resection (-5.4%; 95% CI, -10.0% to -0.5%; P = .03) and higher cost of hepatic resection (13.4%; 95% CI, 8.2% to 18.8%; P markets relative to moderately concentrated markets, although overall charges were 8.3% lower (95% CI, -14.0% to -2.3%; P = .008) in highly concentrated markets. For hepatic resections, hospitals in highly concentrated markets had 8.4% lower costs (95% CI, -13.0% to -3.6%; P = .001) compared with those in unconcentrated markets and charges that were 13.4% lower (95% CI, -19.3% to -7.1%; P markets and 10.5% lower (95% CI, -16.2% to -4.4%; P = .001) compared with unconcentrated markets.

Urine drug testing is commonly performed in both clinical and forensic arenas for screening, monitoring and compliance purposes. We sought to determine if urine creatinine concentrations in monitoring program participants were significantly different from hospital in-patients and out-patients undergoing urine drug testing. We retrospectively reviewed urine creatinine submitted in June through December 2015 for all specimens undergoing urine drug testing. The 20,479 creatinine results were categorized as hospitalized patients (H) and monitoring/compliance groups for pain management (P), legal (L) or recovery (R). Median creatinine concentrations (interquartile range, mg/dL) were significantly different (P creatinine concentrations were significantly lower in the R vs. L group (Pcreatinine concentration and may indicate participants' attempts to tamper with their drug test results through dilution means. © The Author 2016.

Community-based palliative care is known to be associated with reduced acute care health service use. Our objective was to investigate how reduced acute care hospital use in the last year of life varied temporally and by patient factors. A retrospective cohort study of the last year of life of 12,763 Western Australians who died from cancer or one of seven non-cancer conditions. Outcome measures were rates of hospital admissions and mean length of hospital stays. Multivariate analyses involved time-to-event and population averaged log-link gamma models. There were 28,939 acute care overnight hospital admissions recorded in the last year of life, an average of 2.3 (SD 2.2) per decedent and a mean length of stay of 9.2 (SD 10.3) days. Overall, the rate of hospital admissions was reduced 34% (95%CI 1-66) and the mean length of stay reduced 6% (95%CI 2-10) during periods of time decedents received community-based palliative care compared to periods of time not receiving this care. Decedents aged community-based palliative care showed a reduced rate of hospital admission around five months before death, whereas for older decedents the reduction in hospital admissions was apparent a year before death. All decedents who were receiving community-based palliative care tended towards shorter hospital stays in the last month of life. Decedents with neoplasms had a mean length of stay three weeks prior to death while not receiving community-based palliative care of 9.6 (95%CI 9.3-9.9) days compared to 8.2 (95% CI 7.9-8.7) days when receiving community-based palliative care. Rates of hospital admission during periods of receiving community-based palliative care were reduced with benefits evident five months before death and even earlier for older decedents. The mean length of hospital stay was also reduced while receiving community-based palliative care, mostly in the last month of life.

Full Text Available BACKGROUND: Severe illness due to 2009 pandemic A(H1N1 infection has been reported among persons who are obese or morbidly obese. We assessed whether obesity is a risk factor for hospitalization and death due to 2009 pandemic influenza A(H1N1, independent of chronic medical conditions considered by the Advisory Committee on Immunization Practices (ACIP to increase the risk of influenza-related complications. METHODOLOGY/PRINCIPAL FINDINGS: We used a case-cohort design to compare cases of hospitalizations and deaths from 2009 pandemic A(H1N1 influenza occurring between April-July, 2009, with a cohort of the U.S. population estimated from the 2003-2006 National Health and Nutrition Examination Survey (NHANES; pregnant women and children or=20 year olds, hospitalization was associated with being morbidly obese (BMI>or=40 for individuals with ACIP-recognized chronic conditions (OR = 4.9, 95% CI 2.4-9.9 and without ACIP-recognized chronic conditions (OR = 4.7, 95%CI 1.3-17.2. Among 2-19 year olds, hospitalization was associated with being underweight (BMIor=20 years without ACIP-recognized chronic medical conditions death was associated with obesity (OR = 3.1, 95%CI: 1.5-6.6 and morbid obesity (OR = 7.6, 95%CI 2.1-27.9. CONCLUSIONS/SIGNIFICANCE: Our findings support observations that morbid obesity may be associated with hospitalization and possibly death due to 2009 pandemic H1N1 infection. These complications could be prevented by early antiviral therapy and vaccination.

To seek a exact method of estimating postmortem interval (PMI). This study detected the concentration of magnesium (Mg) and iron (Fe) in vitreous humor of rabbit at 96 h after death and explored the relationship between their concentration and PMI using a method ICP-MS. The concentra-tion of Mg in vitreous humor of rabbit at 48 h after death and Fe in vitreous humor of rabbit at 6-48 h after death were related to PMI significantly. The formulae of the relationship between PMI and Mg concentrations is y = 0.0738x2 + 0.6997x + 11.45 (within 48 h, R2 = 0.9119). The formulae of the relationship between PMI and Fe concentrations is y = 0.0411x2 - 0.3148x + 1.4113 (within 6-48 h, R2 = 0.9594). The concentration of Mg in vitreous humor of rabbit at 48 h after death and Fe in vitreous humor of rabbit at 6-48 h after death may be as reference indicator to estimate PMI.

Full Text Available Purpose: Maternal group B Streptococcus (GBS can be transmitted from a colonized mother to newborn during vaginal delivery and may or may not contribute to infant death. This study aimed to explore the geographic distribution and risk factors of maternal GBS colonization and infant death during birth hospitalization. Methods: We retrospectively studied mothers with live birth(s in a large eastern Wisconsin hospital system from 2007 through 2013. Associations between maternal and neonatal variables, GBS colonization and infant death were examined using chi-squared, Mann-Whitney U and t-tests. Multivariable logistic regression models also were developed. Results: Study population (N = 99,305 had a mean age of 28.1 years and prepregnancy body mass index (BMI of 26.7 kg/m2; 64.0% were white, 59.2% married, 39.3% nulliparous and 25.7% cesarean delivery. Mean gestational age was 39.0 weeks. Rate of maternal GBS colonization (22.3% overall was greater in blacks (34.1% vs. 20.1% in whites, P < 0.0001, unmarried women (25.5% vs. 20.0% married, P < 0.0001, women with sexually transmitted or other genital infections (P < 0.0001 and residents of ZIP code group 532XX (P < 0.0001, and was associated with increasing BMI (P < 0.0001. All predictors of colonization were significant on multivariable analysis. Rate of infant death was 5.7 deaths/1,000 live births (n = 558 excluding lethal anomalies and stillbirths and was negatively associated with maternal GBS colonization (P < 0.0001. On multivariable analysis, 532XX ZIP code group, lower gestational age, preterm labor, hyaline membrane disease, normal spontaneous vaginal delivery, hydramnios, oligohydramnios and absence of maternal GBS were associated with infant death. Conclusions: Geographic characteristics were associated with infant death and maternal GBS colonization. Further research is needed to determine if increased surveillance or treatment of mothers colonized with GBS decreases the risk of infant

Globally, clinical certification of the cause of neonatal death is not commonly available in developing countries. Under such circumstances it is imperative to use available WHO verbal autopsy tool to ascertain causes of death for strategic health planning in countries where resources are limited and the burden of neonatal death is high. The study explores the diagnostic accuracy of WHO revised verbal autopsy tool for ascertaining the causes of neonatal deaths against reference standard diagnosis obtained from standardized clinical and supportive hospital data. All neonatal deaths were recruited between August 2006 -February 2008 from two tertiary teaching hospitals in Province Sindh, Pakistan. The reference standard cause of death was established by two senior pediatricians within 2 days of occurrence of death using the International Cause of Death coding system. For verbal autopsy, trained female community health worker interviewed mother or care taker of the deceased within 2-6 weeks of death using a modified WHO verbal autopsy tool. Cause of death was assigned by 2 trained pediatricians. The performance was assessed in terms of sensitivity and specificity. Out of 626 neonatal deaths, cause-specific mortality fractions for neonatal deaths were almost similar in both verbal autopsy and reference standard diagnosis. Sensitivity of verbal autopsy was more than 93% for diagnosing prematurity and 83.5% for birth asphyxia. However the verbal autopsy didn't have acceptable accuracy for diagnosing the congenital malformation 57%. The specificity for all five major causes of neonatal deaths was greater than 90%. The WHO revised verbal autopsy tool had reasonable validity in determining causes of neonatal deaths. The tool can be used in resource limited community-based settings where neonatal mortality rate is high and death certificates from hospitals are not available.

2015-01-01

According to the requirements of the tritium related systems of the TBM (Test Blanket Module) for monitoring the on-line tritium concentration, a wide-range tritium-concentration detector has been developed to measure the tritium concentration in the range of 10 4 Bq/ml - 5*10 8 Bq/ml. This detector is combined with a low-memory helium ionization chamber. The weak current signal collected in the ionization chamber is converted to the voltage signal by an I-V converter. The minimum weak current which the detector could be measured is 10 -14 A. The performance of the background current and the current response linearity of the prototype have been tested. The test result indicates that the linear response of the current signal of the prototype without connecting the ionization chamber is good. The linear correlation coefficient is R 2 = 0.998

2017-01-01

Living conditions in Nazi concentration camps were harsh and inhumane, leading many prisoners to commit suicide. Sachsenhausen (Oranienburg, Germany) was a concentration camp that operated from 1936 to 1945. More than 200,000 people were detained there under Nazi rule. This study analyzes deaths classified as suicides by inmates in this camp, classified as homosexuals, both according to the surviving Nazi files. This collective was especially repressed by the Nazi authorities. Data was collected from the archives of Sachsenhausen Memorial and the International Tracing Service in Bad Arolsen. Original death certificates and autopsy reports were reviewed. Until the end of World War II, there are 14 death certificates which state "suicide" as cause of death of prisoners classified as homosexuals, all of them men aged between 23 and 59 years and of various religions and social strata. Based on a population of 1,200 prisoners classified as homosexuals, this allows us to calculate a suicide rate of 1,167/100,000 (over the period of eight years) for this population, a rate 10 times higher than for global inmates (111/100,000). However, our study has several limitations: not all suicides are registered; some murders were covered-up as suicides; most documents were lost during the war or destroyed by the Nazis when leaving the camps and not much data is available from other camps to compare. We conclude that committing suicides in Sachsenhausen was a common practice, although accurate data may be impossible to obtain.

Citalopram (CT) and escitalopram (S-CT) are among the most widely prescribed selective serotonin reuptake inhibitors used to treat major depressive disorder (MDD). We applied a genome-wide association study to identify genetic factors that contribute to variation in plasma concentrations of CT or S-CT and their metabolites in MDD patients treated with CT or S-CT. Our genome-wide association study was performed using samples from 435 MDD patients. Linear mixed models were used to account for within-subject correlations of longitudinal measures of plasma drug/metabolite concentrations (4 and 8 weeks after the initiation of drug therapy), and single-nucleotide polymorphisms (SNPs) were modelled as additive allelic effects. Genome-wide significant associations were observed for S-CT concentration with SNPs in or near the CYP2C19 gene on chromosome 10 (rs1074145, P = 4.1 × 10(-9) ) and with S-didesmethylcitalopram concentration for SNPs near the CYP2D6 locus on chromosome 22 (rs1065852, P = 2.0 × 10(-16) ), supporting the important role of these cytochrome P450 (CYP) enzymes in biotransformation of citalopram. After adjustment for the effect of CYP2C19 functional alleles, the analyses also identified novel loci that will require future replication and functional validation. In vitro and in vivo studies have suggested that the biotransformation of CT to monodesmethylcitalopram and didesmethylcitalopram is mediated by CYP isozymes. The results of our genome-wide association study performed in MDD patients treated with CT or S-CT have confirmed those observations but also identified novel genomic loci that might play a role in variation in plasma levels of CT or its metabolites during the treatment of MDD patients with these selective serotonin reuptake inhibitors. © 2014 The British Pharmacological Society.

We aimed to derive and validate a single risk score for predicting death from ischemic stroke (IS), intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH). Data from 333 865 stroke patients (IS, 82.4%; ICH, 11.2%; SAH, 2.6%; uncertain type, 3.8%) in the Get With The Guidelines-Stroke database were used. In-hospital mortality varied greatly according to stroke type (IS, 5.5%; ICH, 27.2%; SAH, 25.1%; unknown type, 6.0%; Pmortality and to assign point scores for a prediction model in the overall population and in the subset with the National Institutes of Health Stroke Scale (NIHSS) recorded (37.1%). The c statistic, a measure of how well the models discriminate the risk of death, was 0.78 in the overall validation sample and 0.86 in the model including NIHSS. The model with NIHSS performed nearly as well in each stroke type as in the overall model including all types (c statistics for IS alone, 0.85; for ICH alone, 0.83; for SAH alone, 0.83; uncertain type alone, 0.86). The calibration of the model was excellent, as demonstrated by plots of observed versus predicted mortality. A single prediction score for all stroke types can be used to predict risk of in-hospital death following stroke admission. Incorporation of NIHSS information substantially improves this predictive accuracy.

Guatemala during 2000, comparing characteristics of intra- and extra-hospital maternal deaths. Multivariate statistical analysis was conducted using Stata 7.0 software RESULTS: Out of 649 registered MM cases, 270 (41.6% were classified as intra-hospital MM and 379 (58.4% as extra-hospital MM. A larger proportion of deaths occurred in women over 35 years of age (29.28%, those of indigenous ethnicity (65.49%, married or cohabiting (87.83%, who had unpaid employment (94.78%, and without formal education (66.56%. Compared with intra-hospital MM cases, the risk of extra-hospital MM was greater among indigenous women (OR 3.4; CI95% 2.8-5.3, those who had unpaid employment (OR 8.95; CI95% 1.7-46.4, a low level of formal education (OR 1.96; CI95% 1.0-3.8 and hemorrhaging as the immediate cause of death (OR 4.28; CI95% 2.3-7.9. CONCLUSIONS: Although some characteristics of intra- and extra-hospital MM cases are similar, a greater proportion of deaths were extra-hospital. This could be related to the high percentage of the population that lives in rural or marginalized areas, which in addition to certain cultural aspects (related to the fact that most of the population is indigenous may impede access to health services. The results of this study can be useful for determining intervention strategies to prevent maternal mortality in intra- and extra-hospital contexts in Guatemala.

Amphetamine its methylendioxy (methylendioxyamphetamine methylenedioxymethylamphetamine, methylenedioxyethylamphetamine) and methoxy derivatives (p-methoxyamphetamine and p-methoxymethylamphetamine) are widely abused in Spanish society. We present here the results of a systematic study of all cases of deaths brought to the attention of the Madrid department of the Instituto Nacional de Toxicologia from 1993 to 1995 in which some of these drugs have been found in the cadaveric blood. The cases were divided into three categories: amphetamine and derivatives, amphetamines and alcohol, amphetamines and other drugs. Data on age, sex, clinical symptoms, morphological findings, circumstances of death, when known, and concentration of amphetamine derivatives, alcohol and other drugs in blood are given for each group. The information provided here may prove to be useful for the forensic interpretation of deaths which are directly or indirectly related to abuse of amphetamine derivatives.

Concentration in the Greek private hospital sector: a descriptive analysis.

Boutsioli, Zoe

2007-07-01

Over the last 20 years, governments all around the world have attempted to boost the role of market and competition in health care industries in order to increase efficiency and reduce costs. The increased competition and the significant implications on costs and prices of health care services resulted in health care industries being transformed. Large firms are merging and acquiring other firms. If this trend continues, few firms will dominate the health care markets. In this study, I use the simple concentration ratio (CR) for the largest 4, 8 and 20 companies to measure the concentration of Greek private hospitals during the period 1997-2004. Also, the Gini coefficient for inequality is used. For the two different categories of hospitals used (a) general and neuropsychiatric and (b) obstetric/gynaecological it is evident that the top four firms of the first category accounted for 43% of sales in 1997, and 52% in 2004, while the four largest firms of the second category accounted for almost 83% in 1997, and 81% in 2004. Also, the Gini coefficient increases over the 8-year period examined from 0.69 in 1997 to 0.82 in 2004. It explains that the market of the private health care services becomes less equal in the sense that fewer private hospitals and clinics hold more and more of the share of the total sales. From a cross-industry analysis it is clear that the private hospital sector has the highest concentration rate. Finally, it appears that the market structure of the private hospitals in Greece resembles more closely to an oligopoly rather than a monopolistic competition, since very few firms dominate the market.

To control carbapenem-resistant Pseudomonas aeruginosa, we implemented a hospital-wide policy concerning the selective use of carbapenems based on the monitoring of P. aeruginosa isolates for susceptibility to five carbapenems using a customized dry plate method. In this study, we retrospectively investigated the outcome of our measures to control carbapenem-resistant P. aeruginosa. To select effective carbapenems, 100 clinical isolates were collected, and the minimum inhibitory concentration (MIC) to 5 carbapenems (IPM/CS, MEPM, DRPM, BIPM and PAPM/BP) was monitored using a customized dry plate method from 2006 to 2013. Carbapenems, which were associated with a high rate of drug resistance in P. aeruginosa, were restricted from use during our intervention study. The antimicrobial use density per 100 bed-days (AUD 100 ) of carbapenems and the detection rates of carbapenem (IPM/CS and MEPM)-resistant P. aeruginosa were determined during the period of the intervention. The isolates consistently showed higher rates of drug-resistant P. aeruginosa in IPM/CS and PAPM/BP. Thus, DRPM, MEPM and BIPM were adopted for hospital-wide use. The detection rates of all IPM/Cs and MEPM-resistant P. aeruginosa significantly decreased. Meanwhile, the consumption of carbapenems showed an increasing trend. The outcome of the hospital-wide implementation of the selective use of carbapenems based on periodic monitoring of the susceptibility of P. aeruginosa isolates was retrospectively studied. Implementation of this measure might have contributed in part to the control of carbapenem-resistant P. aeruginosa in our hospital.

According to the requirements of the tritium related systems of the TBM (Test Blanket Module) for monitoring the on-line tritium concentration, a wide-range tritium-concentration detector has been developed to measure the tritium concentration in the range of 10{sup 4} Bq/ml - 5*10{sup 8} Bq/ml. This detector is combined with a low-memory helium ionization chamber. The weak current signal collected in the ionization chamber is converted to the voltage signal by an I-V converter. The minimum weak current which the detector could be measured is 10{sup -14} A. The performance of the background current and the current response linearity of the prototype have been tested. The test result indicates that the linear response of the current signal of the prototype without connecting the ionization chamber is good. The linear correlation coefficient is R{sup 2} = 0.998.

Agreement between death-certificate and autopsy diagnoses among atomic-bomb survivors

1993-11-01

Using the Atomic Bomb Casualty Commission/Radiation Effects Research Foundation series of over 5000 autopsies, we examined death-certificate accuracy for several disease categories and assessed the effect of potential modifying factors on this accuracy. For 12 cause-of-death categories, the overall percent agreement between death-certificate and autopsy diagnoses was only 52.5%. Although neoplasms had the highest detection rate (on the death certificate) in the study, still almost 25% of cancers diagnosed at autopsy were missed on the death certificate. Only for neoplasms and external causes of death were confirmation and detection rates above 70%. Confirmation rates were between 50% and 70% for infectious and parasitic diseases and heart and other vascular diseases. Detection rates reached a similar level for infectious and parasitic, cerebrovascular, and digestive diseases. Specificity rates were above 90% for all but the cerebrovascular disease category. Overall agreement decreased with increasing age of the decedents and was lower for deaths occurring outside of hospital vs those occurring in a hospital. There was some suggestion that agreement rates were higher for more-recent deaths but no indication that radiation dose, sex, city of residence, or inclusion in a biennial clinical-examination program influenced agreement. Because the inaccuracy of death-certificate diagnoses can have major implications for many aspects of health research and planning, it is important to be aware that death-certificate accuracy is low and can vary widely depending on the patient's age at death and the place of death.

Accurate cause of death coding leads to organised and usable death information but there are some factors that influence documentation on death certificates and therefore affect the coding. We reviewed the role of documentation errors on the accuracy of death coding at Shahid Mohammadi Hospital (SMH), Bandar Abbas, Iran. We studied the death certificates of all deceased patients in SMH from October 2010 to March 2011. Researchers determined and coded the underlying cause of death on the death certificates according to the guidelines issued by the World Health Organization in Volume 2 of the International Statistical Classification of Diseases and Health Related Problems-10th revision (ICD-10). Necessary ICD coding rules (such as the General Principle, Rules 1-3, the modification rules and other instructions about death coding) were applied to select the underlying cause of death on each certificate. Demographic details and documentation errors were then extracted. Data were analysed with descriptive statistics and chi square tests. The accuracy rate of causes of death coding was 51.7%, demonstrating a statistically significant relationship (p=.001) with major errors but not such a relationship with minor errors. Factors that result in poor quality of Cause of Death coding in SMH are lack of coder training, documentation errors and the undesirable structure of death certificates.

To compare the risk of in-hospital mortality associated with haloperidol compared with atypical antipsychotics in patients admitted to hospital with acute myocardial infarction. Cohort study using a healthcare database. Nationwide sample of patient data from more than 700 hospitals across the United States. 6578 medical patients aged more than 18 years who initiated oral haloperidol or oral atypical antipsychotics (olanzapine, quetiapine, risperidone) during a hospital admission with a primary diagnosis of acute myocardial infarction between 2003 and 2014. In-hospital mortality during seven days of follow-up from treatment initiation. Among 6578 patients (mean age 75.2 years) treated with an oral antipsychotic drug, 1668 (25.4%) initiated haloperidol and 4910 (74.6%) initiated atypical antipsychotics. The mean time from admission to start of treatment (5.3 v 5.6 days) and length of stay (12.5 v 13.6 days) were similar, but the mean treatment duration was shorter in patients using haloperidol compared with those using atypical antipsychotics (2.4 v 3.9 days). 1:1 propensity score matching was used to adjust for confounding. In intention to treat analyses with the matched cohort, the absolute rate of death per 100 person days was 1.7 for haloperidol (129 deaths) and 1.1 for atypical antipsychotics (92 deaths) during seven days of follow-up from treatment initiation. The survival probability was 0.93 in patients using haloperidol and 0.94 in those using atypical antipsychotics at day 7, accounting for the loss of follow-up due to hospital discharge. The unadjusted and adjusted hazard ratios of death were 1.51 (95% confidence interval 1.22 to 1.85) and 1.50 (1.14 to 1.96), respectively. The association was strongest during the first four days of follow-up and decreased over time. By day 5, the increased risk was no longer evident (1.12, 0.79 to 1.59).

Full Text Available There are few studies that approach the epidemiology of deaths in racehorses in a broad manner. The majority focus on a specific affection or procedure. Brazil does not have a program instituted for the monitoring of deaths of horses. By means of a descriptive study in association with a multivariate analysis method, an epidemiologic profile was determined for deaths related to musculoskeletal (MS, gastrointestinal (GI, respiratory (RES systems, neurologic origin (NEU and sudden death (SD for the years of 2002 to 2008, at the Octavio Dupont Veterinary Hospital-Rio de Janeiro (ODVH. Males comprised the majority of deaths and that deaths were related to, decreasing order, MS>GI>SD>NEU>RES, with respect to general mortality rate per large group of determined causes (TSPMr. The majority of deaths registered included horses aged four to five years (ID4-ID5. We observed the following correspondence relations: (3-year period = SM - ID>5 - SD; ID>5 - GI; ID4-5 - MS; SF - ID5 - GI; SF - ID5. The present study points out the importance and necessity of epidemiologic studies of lesions in horses, based on diagnosis for the recognition of predisposing factors and prevention.

Full Text Available BACKGROUND: Diarrhea is a leading cause of childhood morbidity and mortality in sub-Saharan Africa. Data on risk factors for mortality are limited. We conducted hospital-based surveillance to characterize the etiology of diarrhea and identify risk factors for death among children hospitalized with diarrhea in rural western Kenya. METHODS AND FINDINGS: We enrolled all children <5 years old, hospitalized with diarrhea (≥3 loose stools in 24 hours at two district hospitals in Nyanza Province, western Kenya. Clinical and demographic information was collected. Stool specimens were tested for bacterial and viral pathogens. Bivariate and multivariable logistic regression analyses were carried out to identify risk factors for death. From May 23, 2005 to May 22, 2007, 1,146 children <5 years old were enrolled; 107 (9% children died during hospitalization. Nontyphoidal Salmonella were identified in 10% (118, Campylobacter in 5% (57, and Shigella in 4% (42 of 1,137 stool samples; rotavirus was detected in 19% (196 of 1,021 stool samples. Among stools from children who died, nontyphoidal Salmonella were detected in 22%, Shigella in 11%, rotavirus in 9%, Campylobacter in 5%, and S. Typhi in <1%. In multivariable analysis, infants who died were more likely to have nontyphoidal Salmonella (adjusted odds ratio [aOR] = 6·8; 95% CI 3·1-14·9, and children <5 years to have Shigella (aOR = 5·5; 95% CI 2·2-14·0 identified than children who survived. Children who died were less likely to be infected with rotavirus (OR = 0·4; 95% CI 0·2-0·8. Further risk factors for death included being malnourished (aOR = 4·2; 95% CI 2·1-8·7; having oral thrush on physical exam (aOR = 2·3; 95% CI 1·4-3·8; having previously sought care at a hospital for the illness (aOR = 2·2; 95% CI 1·2-3·8; and being dehydrated as diagnosed at discharge/death (aOR = 2·5; 95% CI 1·5-4·1.

Full Text Available Abstract Objective: To characterize varicella zoster virus-related deaths and hospitalizations in Brazil before universal vaccination with the tetravalent (measles, mumps, rubella, and varicella vaccine, attempting to collect baseline data on varicella morbidity and mortality in order to evaluate the impact of the varicella vaccination program. Methods: Varicella-associated mortality data were evaluated between 1996 and 2011 and varicella zoster virus-associated hospitalizations between 1998 and 2013. Data were gathered from the Informatics Department of the Unified Health System, considering the International Classification of Diseases, 10th Revision, code B01. All age groups were assessed. Varicella-specific mortality rates were calculated and seasonality of varicella-zoster virus-associated hospitalizations was described. Results: There were 2334 varicella deaths between 1996 and 2011, 19.3% in infants aged less than 1 year and 36% in children from 1 to 4 years. In infants under 1 year, varicella mortality rates reached 3.2/100,000/year. In children aged 1–4 years, varicella mortality rates reach 1.64/100,000/year. Average annual mortality rates for varicella in Brazil are 0.88/100,000 in infants under 1 year and 0.40/100,000 in children aged 1–4 years. The total number of hospitalizations associated with varicella zoster virus was 62,246 from 2008 to 2013. Varicella-associated hospitalizations have a seasonal distribution in children, peaking in November. In the elderly, monthly averages of herpes zoster-associated hospitalizations present no significant seasonal variation. Conclusions: Varicella is associated, in the pre-vaccine period, to significant morbidity and mortality in Brazil. The universal vaccination program is expected to decrease the disease burden from varicella.

How do health insurer market concentration and bargaining power with hospitals affect health insurance premiums?

Trish, Erin E; Herring, Bradley J

2015-07-01

The US health insurance industry is highly concentrated, and health insurance premiums are high and rising rapidly. Policymakers have focused on the possible link between the two, leading to ACA provisions to increase insurer competition. However, while market power may enable insurers to include higher profit margins in their premiums, it may also result in stronger bargaining leverage with hospitals to negotiate lower payment rates to partially offset these higher premiums. We empirically examine the relationship between employer-sponsored fully-insured health insurance premiums and the level of concentration in local insurer and hospital markets using the nationally-representative 2006-2011 KFF/HRET Employer Health Benefits Survey. We exploit a unique feature of employer-sponsored insurance, in which self-insured employers purchase only administrative services from managed care organizations, to disentangle these different effects on insurer concentration by constructing one concentration measure representing fully-insured plans' transactions with employers and the other concentration measure representing insurers' bargaining with hospitals. As expected, we find that premiums are indeed higher for plans sold in markets with higher levels of concentration relevant to insurer transactions with employers, lower for plans in markets with higher levels of insurer concentration relevant to insurer bargaining with hospitals, and higher for plans in markets with higher levels of hospital market concentration.

 The role of drug concentrations in clinical outcomes in children with tuberculosis is unclear. Target concentrations for dose optimization are unknown.  Plasma drug concentrations measured in Indian children with tuberculosis were modeled using compartmental pharmacokinetic analyses. The children were followed until end of therapy to ascertain therapy failure or death. An ensemble of artificial intelligence algorithms, including random forests, was used to identify predictors of clinical outcome from among 30 clinical, laboratory, and pharmacokinetic variables.  Among the 143 children with known outcomes, there was high between-child variability of isoniazid, rifampin, and pyrazinamide concentrations: 110 (77%) completed therapy, 24 (17%) failed therapy, and 9 (6%) died. The main predictors of therapy failure or death were a pyrazinamide peak concentration <38.10 mg/L and rifampin peak concentration <3.01 mg/L. The relative risk of these poor outcomes below these peak concentration thresholds was 3.64 (95% confidence interval [CI], 2.28-5.83). Isoniazid had concentration-dependent antagonism with rifampin and pyrazinamide, with an adjusted odds ratio for therapy failure of 3.00 (95% CI, 2.08-4.33) in antagonism concentration range. In regard to death alone as an outcome, the same drug concentrations, plus z scores (indicators of malnutrition), and age <3 years, were highly ranked predictors. In children <3 years old, isoniazid 0- to 24-hour area under the concentration-time curve <11.95 mg/L × hour and/or rifampin peak <3.10 mg/L were the best predictors of therapy failure, with relative risk of 3.43 (95% CI, .99-11.82).  We have identified new antibiotic target concentrations, which are potential biomarkers associated with treatment failure and death in children with tuberculosis. © The Author 2016.

Children with diarrhea hospitalized for respiratory distress often have fatal outcome in resource-limited settings, although data are lacking on risk factors for death in such children. We sought to evaluate clinical predictors for death in such children. In this prospective cohort study, we enrolled under-5 children with diarrhea admitted with severe respiratory distress to the intensive care unit of Dhaka Hospital of International Centre for Diarhoeal Disease Research, Bangladesh, from September 2014 through September 2015. We compared clinical and laboratory characteristics between study children those who died (n = 29) and those who survived (n = 62). In logistic regression analysis, after adjusting for potential confounders, the independent predictors for death in children hospitalized for diarrhea and severe respiratory distress were severe sepsis and hypoglycemia ( P < .05 for all). Thus, recognition of these simple parameters may help clinicians identify children with diarrhea at risk of deaths in order to initiate prompt management for the better outcome, especially in resource-poor settings.

To determine the causes of neonatal deaths and their contributing factors. We used the "three-delay model" to conduct an audit of the neonatal deaths that occurred between January 2006 and December 2010 at the Charles de Gaulle University Pediatric Hospital, in Ouagadougou. The neonatal mortality rate was 12.3%. The main direct causes were infections (70%), cerebral distress (10%), respiratory distress (7%), congenital malformations (5.5%), prematurity (4.5%) and hemorrhagic syndromes (3%). All three delays were found: in decision making in 64.4% of cases, in access to health services in 77%, and in receiving appropriate care in 66.9%; they multiplied the risk of death by a factor of 4, 3 and 5, respectively. To reduce deaths of newborn babies, it is necessary to overcome the three delays that contribute to it, pending the improvement of socioeconomic conditions of populations. This combat requires optimizing the implementation of the subsidies for obstetric and neonatal emergency care and strengthening the involvement of all stakeholders, specifically, policy makers, the community and health professionals.

Guerrero, Chiapas, and Oaxaca, respectively.Where accurate International Classification of Diseases (ICD-coded cause-of-death data are available for deaths in hospital and for VR covering a subset of the population, we demonstrated that population CSMFs can be estimated with low average error. In addition, we showed in the case of Mexico that this method can substantially reduce error from biased hospital data, even when applied to areas with widely different levels of development. For countries with ICD-coded deaths in hospital, this method potentially allows the use of existing data to inform health policy.

To describe a novel approach to hospital mortality meetings to elucidate understanding of contributory factors to child death and inform practice in the National Health Service. All child deaths were separately reviewed at a meeting attended by professionals across the healthcare pathway, and an assessment was made of contributory factors to death across domains intrinsic to the child, family and environment, parenting capacity and service delivery. Data were analysed from a centrally held database of records. All child deaths in a tertiary children's hospital between 1 April 2010 and 1 April 2013. Descriptive data summarising contributory factors to child deaths. 95 deaths were reviewed. In 85% cases, factors intrinsic to the child provided complete explanation for death. In 11% cases, factors in the family and environment and, in 5% cases, factors in parenting capacity, contributed to patient vulnerability. In 33% cases, factors in service provision contributed to patient vulnerability and in two patients provided complete explanation for death. 26% deaths were classified as potentially preventable and in those cases factors in service provision were more commonly identified than factors across other domains (OR: 4.89; 95% CI 1.26 to 18.9). Hospital child death review meetings attended by professionals involved in patient management across the healthcare pathway inform understanding of events leading to a child's death. Using a bioecological approach to scrutinise contributory factors the multidisciplinary team concluded most deaths occurred as a consequence of underlying illness. Although factors relating to service provision were commonly identified, they rarely provided a complete explanation for death. Efforts to reduce child mortality should be driven by an understanding of modifiable risk factors. Systematic data collection arising from a standardised approach to hospital reviews should be the basis for national mortality review processes and database

Full Text Available Background: The hospital environment requires special attention to provide healthful indoor air quality for protecting patients and healthcare workers against the occupational diseases. The aim of this study was to determine the concentrations of respirable particles indoor and ambient air of two hospitals in Kashan. Materials and Method: This cross-sectional study was conducted during 3 months (Marth 2014 to May 2015. Indoor and outdoor PM10 and PM2.5 concentrations were measured four times a week in the operating room, pediatric and ICU2 (Intensive Care Unit wards using a real time dust monitor at two hospitals. A total number of 480 samples (80 samples indoors and 40 outdoors from wards were collected. Results: The highest mean PM2.5 and PM10 for indoors were determined 57.61± 68.57 µg m-3 and 212.36±295.49 µg m-3, respectively. The results showed a significant relationship between PM2.5 and PM10 in the indoor and ambient air of two hospitals (P<0.05. PM2.5 and PM10 concentrations were different in all of the selected wards (P<0.05. Conclusion: The respirable particle concentrations in the indoor and ambient air in both hospitals were higher than the 24-hours WHO and US-EPA standards. Thence, utilizing sufficient and efficient air conditioning systems in hospitals can be useful in improving indoor air quality and reducing the respirable particle concentrations.

The population of the Pacific Melanesian country of Vanuatu was 234,000 at the 2009 census. Apart from subsistence activities, economic activity includes tourism and agriculture. Current completeness of vital registration is considered too low to be usable for national statistics; mortality and life expectancy (LE) are derived from indirect demographic estimates from censuses/surveys. Some cause of death (CoD) data are available to provide information on major causes of premature death. Deaths 2001-2007 were coded for cause (ICDv10) for ages 0-59 years from: hospital separations (HS) (n = 636), hospital medical certificates (MC) of death (n = 1,169), and monthly reports from community health facilities (CHF) (n = 1,212). Ill-defined causes were 3 % for hospital deaths and 20 % from CHF. Proportional mortality was calculated by cause (excluding ill-defined) and age group (0-4, 5-14 years), and also by sex for 15-59 years. From total deaths by broad age group and sex from 1999 and 2009 census analyses, community deaths were estimated by deduction of hospital deaths MC. National proportional mortality by cause was estimated by a weighted average of MC and CHF deaths. National estimates indicate main causes of deaths <5 years were: perinatal disorders (45 %) and malaria, diarrhea, and pneumonia (27 %). For 15-59 years, main causes of male deaths were: circulatory disease 27 %, neoplasms 13 %, injury 13 %, liver disease 10 %, infection 10 %, diabetes 7 %, and chronic respiratory disease 7 %; and for females: neoplasms 29 %, circulatory disease 15 %, diabetes 10 %, infection 9 %, and maternal deaths 8 %. Infection included tuberculosis, malaria, and viral hepatitis. Liver disease (including hepatitis and cancer) accounted for 18 % of deaths in adult males and 9 % in females. Non-communicable disease (NCD), including circulatory disease, diabetes, neoplasm, and chronic respiratory disease, accounted for 52 % of premature deaths in adult

Ill-defined causes of death are common among the elderly owing to the high frequency of comorbidities and, consequently, to the difficulty in defining the underlying cause of death. To analyze the validity and reliability of the "primary diagnosis" in hospitalization to recover the information on the underlying cause of death in natural deaths among the elderly whose deaths were originally assigned to "ill-defined cause" in their Death Certificate. The hospitalizations occurred in the state of Rio de Janeiro, in 2006. The databases obtained in the Information Systems on Mortality and Hospitalization were probabilistically linked. The following data were calculated for hospitalizations of the elderly that evolved into deaths with a natural cause: concordance percentages, Kappa coefficient, sensitivity, specificity, and the positive predictive value of the primary diagnosis. Deaths related to "ill-defined causes" were assigned to a new cause, which was defined based on the primary diagnosis. The reliability of the primary diagnosis was good, according to the total percentage of consistency (50.2%), and fair, according to the Kappa coefficient (k = 0.4; p values per chapter and grouping of the International Classification of Diseases. The recovery of the information on the primary cause occurred in 22.6% of the deaths with ill-defined causes (n = 14). The methodology developed and applied for the recovery of the information on the natural cause of death among the elderly in this study had the advantage of effectiveness and the reduction of costs compared to an investigation of the death that is recommended in situations of non-linked and low positive predictive values. Monitoring the mortality profile by the cause of death is necessary to periodically update the predictive values.

Wide variation in hospital and physician payment rates evidence of provider market power.

Science.gov (United States)

Ginsburg, Paul B

2010-11-01

Wide variation in private insurer payment rates to hospitals and physicians across and within local markets suggests that some providers, particularly hospitals, have significant market power to negotiate higher-than-competitive prices, according to a new study by the Center for Studying Health System Change (HSC). Looking across eight health care markets--Cleveland; Indianapolis; Los Angeles; Miami; Milwaukee; Richmond, Va.; San Francisco; and rural Wisconsin--average inpatient hospital payment rates of four large national insurers ranged from 147 percent of Medicare in Miami to 210 percent in San Francisco. In extreme cases, some hospitals command almost five times what Medicare pays for inpatient services and more than seven times what Medicare pays for outpatient care. Variation within markets was just as dramatic. For example, the hospital with prices at the 25th percentile of Los Angeles hospitals received 84 percent of Medicare rates for inpatient care, while the hospital with prices at the 75th percentile received 184 percent of Medicare rates. The highest-priced Los Angeles hospital with substantial inpatient claims volume received 418 percent of Medicare. While not as pronounced, significant variation in physician payment rates also exists across and within markets and by specialty. Few would characterize the variation in hospital and physician payment rates found in this study to be consistent with a highly competitive market. Purchasers and public policy makers can address provider market power, or the ability to negotiate higher-than-competitive prices, through two distinct approaches. One is to pursue market approaches to strengthen competitive forces, while the other is to constrain payment rates through regulation.

Road traffic injury surveillance involves methodological difficulties due, among other reasons, to the lack of consensus criteria for case definition. Police records have usually been the main source of information for monitoring traffic injuries, while health system data has hardly been used. Police records usually include comprehensive information on the characteristics of the crash, but often underreport injury cases and do not collect reliable information on the severity of injuries. However, statistics on severe traffic injuries have been based almost exclusively on police data. The aim of this paper is to propose criteria based on medical records to define: a) "Hospital discharge for traffic injuries", b) "Person with severe traffic injury", and c) "Death from traffic injuries" in order to homogenize the use of these sources.

Full Text Available Aims: The aim of this study was to evaluate the bioaerosols level in the various parts of three educational hospitals of Isfahan, Iran. Materials and Methods: The collection of bioaerosols (including bacterial and fungal microorganisms was carried out with one-stage Anderson sampler. The sampling was carried out at the height of 1.5 m from the floor of various hospitals wards (infectious, surgery, urology wards, and operating room. The volume of each sample was determined based on pre-tests carried and was about 50 L. After sampling, the samples were incubated and analyzed. The effect of various environmental conditions including humidity, temperature, and outdoor bioaerosol levels was also investigated. Results: The lowest numbers of fungal and bacterial concentration were obtained in operating rooms of the hospitals and the highest concentration was observed in infectious disease wards of hospital 1 and 2 and surgery ward of hospital 3. The bacterial concentration was observed to be higher in hospital wards than outdoor, except hospitals′ operating rooms. Conclusion: The findings showed that the bioaerosols level in the hospitals was relatively high. The higher levels of indoor bacteria than outdoor might be associated with the presence of patients, their activity, unsuitable ventilation, and disinfection. Therefore, environmental monitoring and control measures are required to improve hospital environmental quality especially in the wards with immune deficiency patients.

To explored the relationship between the concentration of potassium ion as well as sodium ion in the aqueous humor and post-mortem interval (PMI). The concentrations of potassium ion and sodium ion in the aqueous humor of swine within 48 h after death at 4 degrees C and 28 degrees C were detected using Z-500 atomic absorption spectrophotometer. The concentrations of potassium ion and sodium ion in aqueous humor of isolated swine eyeballs within 48 h after death when the environmental temperature was 4 degrees C were significantly related to PMI. The relationship between PMI and the concentration of potassium ion was PMI = -0.178[K+]2 + 49.978 (R2 = 0.995). The relationship between PMI and the rate of sodium ion and potassium ion was PMI = 120.987/[Na+/K+]-28.834 (R2 = 0.905). The concentration of potassium in aqueous humor of isolated swine eyeballs may be one of the reference indicators to estimate PMI of the corpses at lower temperatures.

In Afghanistan, childhood deaths from pneumonia are high. Among 639 children at 1 hospital, the case-fatality rate was 12.1%, and 46.8% of pneumococcal serotypes detected were covered by the 13-valent vaccine. Most deaths occurred within 2 days of hospitalization; newborns and malnourished children were at risk. Vaccination could reduce pneumonia and deaths.

Vehicle crashes are a leading cause of US injury and death. Early death, however, has almost entirely been studied in-hospital. The US Department of Transportation Fatality Analysis Reporting System (FARS) database captures both prehospital and in-hospital mortality. FARS location (prehospital, in-hospital) and time of death were reviewed (1978-2013), and a 2003-2005 subgroup of 55,537 early deaths (i.e., between 5 minutes and 4 hours after injury) was analyzed to quantify risk of death over time. There has been an overall decrease in 1978-2013 US vehicle-related deaths (from 3.3 deaths per 100 million vehicle miles traveled to 1.1 and from 22.6 per 100,000 population to 10.4). Snapshots of the death data reveal an overall downward trend of total in-hospital and prehospital deaths. The proportion of hospital deaths decreased by 58%, whereas the proportion of deaths in the prehospital period increased to 56%. Subgroup analysis revealed a rate of mortality risk of 0.4% per minute for the first 30 minutes, 1% per minute for the next 60 minutes, and 0.2% per minute and plateauing thereafter. Analysis of census FARS data of motor vehicle crash-related deaths showed an overall 35% decrease in mortality over a period of 36 years. The disproportionate reduction in in-hospital deaths is perhaps a testament to the effectiveness of trauma centers. However, there is a demonstrable need to focus on prehospital deaths with resuscitative and adjuvant therapy research and trauma system design. Quantifying risk of death over time should help focus emergency medical services, trauma system, and resuscitation goals. Epidemiologic study, level III.

In the test for retention of the passive avoidance task, amnesia was observed 5 and 7 days after CO-exposure when the mice were exposed to CO 1 day after training; in the case when the mice were exposed to CO 5 and 7 days before training, amnesia was also observed in a retention test given 1 day after training. The number of pyramidal cells in the hippocampal CA1 subfield was lower than that of the control 3, 5 and 7 days after CO-exposure. But the neurodegeneration in the parietal cortex, area 1, was not observed until 7 days after CO-exposure. The findings indicated that the amnesia and the neuronal death were produced after a delay when the mice were exposed to CO. In addition, the delayed amnesia was closely related to the delayed neuronal death in the hippocampal CA1 subfield. Moreover, [3H]glutamate and [3H]glycine binding sites did not change after CO-exposure but, 7 days after CO-exposure, the concentration of acetylcholine and the binding of [3H]quinuclidinyl benzilate in the frontal cortex and the striatum were found to have significantly changed, but those in the hippocampus did not show significant change. Therefore, we suggest that delayed amnesia induced by CO-exposure may result from delayed neuronal death in the hippocampal CA1 subfield and dysfunction in the acetylcholinergic neurons, in the frontal cortex, the striatum and/or the hippocampus

Methods SWOT (strengths, weaknesses, opportunities and threats analysis of the process of maternal death review during a workshop in Malawi. Results Strengths: Availability of data from case notes, support from hospital management, and having maternal death review forms. Weaknesses: fear of blame, lack of knowledge and skills to properly conduct death reviews, inadequate resources and missing documentation. Opportunities: technical assistance from expatriates, support from the Ministry of Health, national protocols and high maternal mortality which serves as motivation factor. Threats: Cultural practices, potential lawsuit, demotivation due to the high maternal mortality and poor planning at the district level. Solutions: proper documentation, conducting maternal death review in a blame-free manner, good leadership, motivation of staff, using guidelines, proper stock inventory and community involvement. Conclusion Challenges encountered during facility-based maternal death review are provider-related, administrative, client related and community related. Countries with similar socioeconomic profiles to Malawi will have similar 'pull-and-push' factors on the process of facility-based maternal death reviews, and therefore we will expect these countries to have similar potential solutions.

Full Text Available To evaluate in-patient mortality and predictors of death associated with convulsive status epilepticus (SE in a large, multi-center, pediatric cohort.We identified our cohort from the KID Inpatient Database for the years 1997, 2000, 2003 and 2006. We queried the database for convulsive SE, associated diagnoses, and for inpatient death. Univariate logistic testing was used to screen for potential risk factors. These risk factors were then entered into a stepwise backwards conditional multivariable logistic regression procedure. P-values less than 0.05 were taken as significant.We identified 12,365 (5,541 female patients with convulsive SE aged 0-20 years (mean age 6.2 years, standard deviation 5.5 years, median 5 years among 14,965,571 pediatric inpatients (0.08%. Of these, 117 died while in the hospital (0.9%. The most frequent additional admission ICD-9 code diagnoses in addition to SE were cerebral palsy, pneumonia, and respiratory failure. Independent risk factors for death in patients with SE, assessed by multivariate calculation, included near drowning (Odds ratio [OR] 43.2; Confidence Interval [CI] 4.4-426.8, hemorrhagic shock (OR 17.83; CI 6.5-49.1, sepsis (OR 10.14; CI 4.0-25.6, massive aspiration (OR 9.1; CI 1.8-47, mechanical ventilation >96 hours (OR9; 5.6-14.6, transfusion (OR 8.25; CI 4.3-15.8, structural brain lesion (OR7.0; CI 3.1-16, hypoglycemia (OR5.8; CI 1.75-19.2, sepsis with liver failure (OR 14.4; CI 5-41.9, and admission in December (OR3.4; CI 1.6-4.1. African American ethnicity (OR 0.4; CI 0.2-0.8 was associated with a decreased risk of death in SE.Pediatric convulsive SE occurs in up to 0.08% of pediatric inpatient admissions with a mortality of up to 1%. There appear to be several risk factors that can predict mortality. These may warrant additional monitoring and aggressive management.

The aim was to determine differences of clinical, treatment and outcome characteristics between patients with in-hospital and out-of-hospital status epilepticus (SE). From 2005 to 2014, clinical data were assessed in adults with SE treated in an academic medical care centre. Clinical characteristics, treatment and outcomes were compared between patients with in-hospital and out-of-hospital SE. Amongst 352 patients, 213 were admitted with SE and 139 developed in-hospital SE. Patients with in-hospital SE had more acute/fatal aetiologies (60% vs. 35%, P Status Epilepticus Severity Score (STESS) was an independent predictor for death in both groups, increased Charlson Comorbidity Index and treatment refractory SE were associated with death only in patients with in-hospital SE. Continuous anaesthesia for refractory SE was associated with increased mortality only in patients with out-of-hospital SE. The area under the receiver operating curve was 0.717 for prediction of death by STESS in patients with in-hospital SE and 0.811 in patients with out-of-hospital SE. Patients with in-hospital SE had more fatal aetiologies and comorbidities, refractory SE, less return to functional baseline, and increased mortality compared to patients with out-of-hospital SE. Whilst the STESS was a robust predictor for death in both groups, the association between continuous anaesthesia and death was limited to out-of-hospital SE. © 2017 EAN.

The seasonal trend of out-of-hospital coronary death (OHCD) and sudden cardiac death has been observed, but whether extreme temperature serves as a risk factor is rarely investigated. We therefore aimed to evaluate the impact of extreme temperatures on OHCDs in China. We obtained death records of 126,925 OHCDs from six large Chinese cities (Harbin, Beijing, Tianjin, Nanjing, Shanghai and Guangzhou) during the period 2009-2011. The short-term associations between extreme temperature and OHCDs were analysed with time-series methods in each city, using generalised additive Poisson regression models. We specified distributed lag non-linear models in studying the delayed effects of extreme temperature. We then applied Bayesian hierarchical models to combine the city-specific effect estimates. The associations between extreme temperature and OHCDs were almost U-shaped or J-shaped. The pooled relative risks (RRs) of extreme cold temperatures over the lags 0-14 days comparing the 1st and 25th centile temperatures were 1.49 (95% posterior interval (PI) 1.26-1.76); the pooled RRs of extreme hot temperatures comparing the 99th and 75th centile temperatures were 1.53 (95% PI 1.27-1.84) for OHCDs. The RRs of extreme temperature on OHCD were higher if the patients with coronary heart disease were old, male and less educated. This multicity epidemiological study suggested that both extreme cold and hot temperatures posed significant risks on OHCDs, and might have important public health implications for the prevention of OHCD or sudden cardiac death.

2014-07-01

Full Text Available Objectives: The hospital standardized mortality ratio (HSMR has been widely used because it allows for robust risk adjustment using administrative data and is important for improving the quality of patient care. Methods: All inpatients discharged from hospitals with more than 700 beds (66 hospitals in 2008 were eligible for inclusion. Using the claims data, 29 most responsible diagnosis (MRDx, accounting for 80% of all inpatient deaths among these hospitals, were identified, and inpatients with those MRDx were selected. The final study population included 703 571 inpatients including 27 718 (3.9% of all inpatients in-hospital deaths. Using logistic regression, risk-adjusted models for predicting in-hospital mortality were created for each MRDx. The HSMR of individual hospitals was calculated for each MRDx using the model coefficients. The models included age, gender, income level, urgency of admission, diagnosis codes, disease-specific risk factors, and comorbidities. The Elixhauser comorbidity index was used to adjust for comorbidities. Results: For 26 out of 29 MRDx, the c-statistics of these mortality prediction models were higher than 0.8 indicating excellent discriminative power. The HSMR greatly varied across hospitals and disease groups. The academic status of the hospital was the only factor significantly associated with the HSMR. Conclusions: We found a large variation in HSMR among hospitals; therefore, efforts to reduce these variations including continuous monitoring and regular disclosure of the HSMR are required.

Death Associated with Inadequate Reassessment of Venous Thromboembolism Prophylaxis at and after Hospital Discharge.

Science.gov (United States)

2015-01-01

Venous thromboembolism (VTE) prophylaxis, also known as thromboprophylaxis, reduces the risk of deep vein thrombosis, pulmonary embolism, and associated complications, including death, in high-risk patients. VTE prophylaxis is recommended for acutely ill, hospitalized medical patients at risk of thrombosis. Anticoagulants, the pharmacologic agents of choice to prevent VTE, are considered high-alert medications. By definition, therefore, anticoagulants bear a hightened risk of causing significant patient harm when they are used in error. As part of ongoing collaboration with a provincial death investigation service, ISMP Canada received a report of a fatal incident that involved continuation of VTE prophylaxis with enoxaparin for a patient discharge to a long-term care (LTC) facility from an acute care setting. The findings and recommendations from this case are charged to highlight the need to build routine reassessment of VTE prophylaxis into the process for discharging patients from the acute care setting and upon transfer to another facility or to primary care. The incident described in this bulletin highlights the importance of continually reassessing the need for VTE prophylaxis, especially at transitions of care, such as discharge from an acute care setting. Evidence and guidelines confirm the benefits of VTE prophylaxis in certain patients during a hospital stay for an acute illness, but the balance of benefits and risks may become unfavourable once the patient is discharged. Clear documentation from the acute care facility can assist the receiving facility and health-care providers, as well as family caregivers, when determining whether thromboprophylaxis is still warranted. Until clear guidance to continue thromboprophylaxis after acute care is available, health-care organizations and practitioners across the spectrum of care are urged to share and consider the strategies presented in this bulletin to ensure the safe use of VTE prophylaxis and improved

The objective was to compare the pattern of exposure to second-hand smoke (SHS) among non-smokers in the general population and in hospitality workers. We used the adult (16-64 years) non-smokers of two independent studies (general population and hospitality workers) in Spain. We assessed the exposure to SHS by means of questionnaire and salivary cotinine concentration. The salivary cotinine concentration by sex, age, educational level, day of week of saliva collection, and exposure to SHS were always higher in hospitality workers than in the general population. Our results indicated that non-smoker hospitality workers have higher levels of exposure to SHS than general population.

Decentralization and task shifting has significantly improved access to antiretroviral therapy (ART). Many studies conducted to determine the attrition rate in Ethiopia have not compared attrition rates between hospitals and health centers in a relatively recent cohort of patients. This study compared death and loss to follow-up (LTFU) rates among ART patients in hospitals and health centers in south Ethiopia. Data routinely collected from patients aged older than 15 years who started ART between July 2011 and August 2012 in 20 selected health facilities (12 being hospitals) were analyzed. The outcomes of interest were LTFU and death. The data were entered, cleaned, and analyzed using Statistical Package for the Social Sciences version 20.0 and Stata version 12.0. Competing-risk regression models were used. The service years of the facilities were similar (median 8 and 7.5 for hospitals and health centers, respectively). The mean patient age was 33.7±9.6 years. The median baseline CD4 count was 179 (interquartile range 93-263) cells/mm(3). A total of 2,356 person-years of observation were made with a median follow-up duration of 28 (interquartile range 22-31) months; 24.6% were either dead or LTFU, resulting in a retention rate of 75.4%. The death rates were 3.0 and 1.5 and the LTFU rate were 9.0 and 10.9 per 100 person-years of observation in health centers and hospitals, respectively. The competing-risk regression model showed that the gap between testing and initiation of ART, body mass index, World Health Organization clinical stage, isoniazid prophylaxis, age, facility type, and educational status were independently associated with LTFU. Moreover, baseline tuberculous disease, poor functional status, and follow-up at a health center were associated with an elevated probability of death. We observed a higher death rate and a lower LTFU rate in health centers than in hospitals. Most of the associated variables were also previously documented. Higher LTFU was

The trade-off between hospital cost and quality of care. An exploratory empirical analysis.

The debate concerning quality of care in hospitals, its "value" and affordability, is increasingly of concern to providers, consumers, and purchasers in the United States and elsewhere. We undertook an exploratory study to estimate the impact on hospital-wide costs if quality-of-care levels were varied. To do so, we obtained costs and service output data regarding 300 U.S. hospitals, representing approximately a 5% cross section of all hospitals operating in 1983; both inpatient and outpatient services were included. The quality-of-care measure used for the exploratory analysis was the ratio of actual deaths in the hospital for the year in question to the forecasted number of deaths for the hospital; the hospital mortality forecaster had earlier (and elsewhere) been built from analyses of 6 million discharge abstracts, and took into account each hospital's actual individual admissions, including key patient descriptors for each admission. Such adjusted death rates have increasingly been used as potential indicators of quality, with recent research lending support for the viability of that linkage. The authors then utilized the economic construct of allocative efficiency relying on "best practices" concepts and peer groupings, built using the "envelopment" philosophy of Data Envelopment Analysis and Pareto efficiency. These analytical techniques estimated the efficiently delivered costs required to meet prespecified levels of quality of care. The marginal additional cost per each death deferred in 1983 was estimated to be approximately $29,000 (in 1990 dollars) for the average efficient hospital. Also, over a feasible range, a 1% increase in the level of quality of care delivered was estimated to increase hospital cost by an average of 1.34%. This estimated elasticity of quality on cost also increased with the number of beds in the hospital.

Preoperative anemia is an established risk factor associated with adverse perioperative outcomes after cardiac surgery. However, limited information exists regarding the relationship between preoperative hemoglobin concentration and outcomes. The aim of this study was to investigate how outcomes are affected by preoperative hemoglobin concentration in a cohort of patients undergoing cardiac surgery. A retrospective, observational cohort study. A single-center tertiary referral hospital. The study comprised 1,972 adult patients undergoing elective and nonelective cardiac surgery. The independent relationship of preoperative hemoglobin concentration was explored on blood transfusion rates, return to the operating room for bleeding and/or cardiac tamponade, postoperative intensive care unit (ICU) and in-hospital length of stay, and mortality. The overall prevalence of anemia was 32% (629/1,972 patients). For every 1-unit increase in hemoglobin (g/dL), blood transfusion requirements were reduced by 11%, 8%, and 3% for red blood cell units, platelet pools, and fresh frozen plasma units, respectively (adjusted incident rate ratio 0.89 [95% CI 0.87-0.91], 0.92 [0.88-0.97], and 0.97 [0.96-0.99]). For each 1-unit increase in hemoglobin (g/dL), the probability (over time) of discharge from the ICU and hospital increased (adjusted hazard ratio estimates 1.04 [1.00-1.08] and 1.12 [1.12-1.16], respectively). A lower preoperative hemoglobin concentration resulted in increased use of hospital resources after cardiac surgery. Each g/dL unit fall in preoperative hemoglobin concentration resulted in increased blood transfusion requirements and increased postoperative ICU and hospital length of stay.

[Organ donation following physician-hastened death at home].

Science.gov (United States)

Mulder, J G H; Sonneveld, J P C

2017-01-01

Patients considering physician-hastened death (PHD) increasingly express a wish to donate organs after death. This fairly unique proposition stems from patients' desire to do something good with (parts of) the same diseased body that has prompted them to request physician-hastened death. In this article we describe a patient with amyotrophic lateral sclerosis (ALS) who expressed this wish. In March 2017 a national guideline on 'Organ donation following physician-hastened death' (ODP) was presented to the Minister of Health, Welfare and Sport of the Netherlands. From the development of this guideline it emerged that, for PHD patients, being forced to experience their final conscious moments in hospital - in order to facilitate organ donation - was a key reason for not choosing ODP. Together with an anaesthesiologist-intensivist, the GP of the ALS patient developed a domestic ODP, thereby overcoming the hurdle of experiencing death in hospital and maintaining the possible option of organ donation. The applied solution is an 'anaesthesia bridge' which separates the experience of farewells, and losing consciousness under pre-medication at home, from biological death and organ donation in hospital.

Home is considered the preferred place of death for many, but patients with haematological malignancies (leukaemias, lymphomas and myeloma) die in hospital more often than those with other cancers and the reasons for this are not wholly understood. We examined preferred and actual place of death among people with these diseases. The study is embedded within an established population-based cohort of patients with haematological malignancies. All patients diagnosed at two of the largest hospitals in the study area between May 2005 and April 2008 with acute myeloid leukaemia, diffuse large B-cell lymphoma or myeloma, who died before May 2010 were included. Data were obtained from medical records and routine linkage to national death records. 323 deceased patients were included. A total of 142 (44%) had discussed their preferred place of death; 45.8% wanted to die at home, 28.2% in hospital, 16.9% in a hospice, 5.6% in a nursing home and 3.5% were undecided; 63.4% of these died in their preferred place. Compared to patients with evidence of a discussion, those without were twice as likely to have died within a month of diagnosis (14.8% vs 29.8%). Overall, 240 patients died in hospital; those without a discussion were significantly more likely to die in hospital than those who had (p≤0.0001). Of those dying in hospital, 90% and 75.8% received haematology clinical input in the 30 and 7 days before death, respectively, and 40.8% died in haematology areas. Many patients discussed their preferred place of death, but a substantial proportion did not and hospital deaths were common in this latter group. There is scope to improve practice, particularly among those dying soon after diagnosis. We found evidence that some people opted to die in hospital; the extent to which this compares with other cancers is of interest. Published by the BMJ Publishing Group Limited.

Pre-hospital haemostatic dressings: a systematic review.

Science.gov (United States)

Granville-Chapman, J; Jacobs, N; Midwinter, M J

2011-05-01

Uncontrolled haemorrhage is a leading cause of prehospital death after military and civilian trauma. Exsanguination from extremity wounds causes over half of preven military combat deaths and wounds to the anatomical junctional zones provide a particular challenge for first responders. Commercial products have been developed, which claim to outperform standard gauze bandages in establishing and maintaining non-surgical haemostasis. Since 2004, two advanced haemostatic dressing products, HemCon and QuikClot have been widely deployed in military operations. Newer products have since become available which aim to provide more efficient haemostasis than and thus supersede HemCon and QuikClot. To conduct a systematic review of clinical and preclinical evidence to compare the relative efficacy and safety of available haemostatic products, which are of relevance to pre-hospital military and civilian emergency medical providers. An English language literature search was performed, using PubMed and Web of Knowledge Databases, with cross-referencing, focussed product searches and communication with product manufacturers. For studies employing animal models, the injury model was required to produce fatal haemorrhage. Products were categorised by primary mode of action as either factor concentrators,mucoadhesive agents or procoagulant supplementors. From 60 articles collated, 6 clinical papers and 37 preclinical animal trials were eligible for inclusion in this review. Products have been tested in three different types of haemorrhage model: low pressure, high volume venous bleeding, high pressure arterial bleeding and mixed arterial-venous bleeding. The efficacy of products varies with the model adopted. Criteria for the 'ideal battle field haemostatic dressing' have previously been defined by Pusateri, but no product has yet attained suchstatus. Since 2004, HemCon (a mucoadhesive agent) and QuikClot (a factor concentrator) have been widely deployed by United States and United

Autopsy is a useful tool for understanding the cause and manner of unexpected patient death. However, the attitudes of the general public and physicians in Japan about clinical autopsy are limited. To describe the beliefs of the general public about whether autopsy should be performed and ascertain if they would actually request one given specific clinical situations where patient death occurred with the additional variable of medical error. To compare these attitudes with previously obtained attitudes of physicians practising at Japanese teaching hospitals. We conducted a cross-sectional study of the general public. We sent standardised questionnaires in 2010 to a randomly selected non-physician adult population using a survey company for participant selection. Respondents gave their opinions about the necessity of autopsy and how they might act given various clinical scenarios of patient death. We compared these results with those of a previous survey of Japanese physicians conducted in 2009. Of the 2300 eligible general adult population, 1575 (68.5%) responded. The majority of the general public indicated they believed an autopsy was necessary. However, in cases of unclear medical error or unclear cause and effect relationship of medical care and patient death, the general public were much less likely to indicate they would actually request an autopsy than were physicians (pcase of error related to death is underway. The results from this study will be important in informing related decisions.

Limited data exist on clinical characteristics and outcomes of patients who had infective endocarditis after undergoing transcatheter aortic valve replacement (TAVR). To determine the associated factors, clinical characteristics, and outcomes of patients who had infective endocarditis after TAVR. The Infectious Endocarditis after TAVR International Registry included patients with definite infective endocarditis after TAVR from 47 centers from Europe, North America, and South America between June 2005 and October 2015. Transcatheter aortic valve replacement for incidence of infective endocarditis and infective endocarditis for in-hospital mortality. Infective endocarditis and in-hospital mortality after infective endocarditis. A total of 250 cases of infective endocarditis occurred in 20 006 patients after TAVR (incidence, 1.1% per person-year; 95% CI, 1.1%-1.4%; median age, 80 years; 64% men). Median time from TAVR to infective endocarditis was 5.3 months (interquartile range [IQR], 1.5-13.4 months). The characteristics associated with higher risk of progressing to infective endocarditis after TAVR was younger age (78.9 years vs 81.8 years; hazard ratio [HR], 0.97 per year; 95% CI, 0.94-0.99), male sex (62.0% vs 49.7%; HR, 1.69; 95% CI, 1.13-2.52), diabetes mellitus (41.7% vs 30.0%; HR, 1.52; 95% CI, 1.02-2.29), and moderate to severe aortic regurgitation (22.4% vs 14.7%; HR, 2.05; 95% CI, 1.28-3.28). Health care-associated infective endocarditis was present in 52.8% (95% CI, 46.6%-59.0%) of patients. Enterococci species and Staphylococcus aureus were the most frequently isolated microorganisms (24.6%; 95% CI, 19.1%-30.1% and 23.3%; 95% CI, 17.9%-28.7%, respectively). The in-hospital mortality rate was 36% (95% CI, 30.0%-41.9%; 90 deaths; 160 survivors), and surgery was performed in 14.8% (95% CI, 10.4%-19.2%) of patients during the infective endocarditis episode. In-hospital mortality was associated with a higher logistic EuroSCORE (23.1% vs 18.6%; odds ratio

To facilitate studies of medications and sudden cardiac death, we developed and validated a computer case definition for these deaths. The study of community dwelling Tennessee Medicaid enrollees 30-74 years of age utilized a linked database with Medicaid inpatient/outpatient files, state death certificate files, and a state 'all-payers' hospital discharge file. The computerized case definition was developed from a retrospective cohort study of sudden cardiac deaths occurring between 1990 and 1993. Medical records for 926 potential cases had been adjudicated for this study to determine if they met the clinical definition for sudden cardiac death occurring in the community and were likely to be due to ventricular tachyarrhythmias. The computerized case definition included deaths with (1) no evidence of a terminal hospital admission/nursing home stay in any of the data sources; (2) an underlying cause of death code consistent with sudden cardiac death; and (3) no terminal procedures inconsistent with unresuscitated cardiac arrest. This definition was validated in an independent sample of 174 adjudicated deaths occurring between 1994 and 2005. The positive predictive value of the computer case definition was 86.0% in the development sample and 86.8% in the validation sample. The positive predictive value did not vary materially for deaths coded according to the ICO-9 (1994-1998, positive predictive value = 85.1%) or ICD-10 (1999-2005, 87.4%) systems. A computerized Medicaid database, linked with death certificate files and a state hospital discharge database, can be used for a computer case definition of sudden cardiac death.

Full Text Available Abstract Background Verbal autopsy has been widely used to estimate causes of death in settings with inadequate vital registries, but little is known about its validity. This analysis was part of Addis Ababa Mortality Surveillance Program to examine the validity of verbal autopsy for determining causes of death compared with hospital medical records among adults in the urban setting of Ethiopia. Methods This validation study consisted of comparison of verbal autopsy final diagnosis with hospital diagnosis taken as a “gold standard”. In public and private hospitals of Addis Ababa, 20,152 adult deaths (15 years and above were recorded between 2007 and 2010. With the same period, a verbal autopsy was conducted for 4,776 adult deaths of which, 1,356 were deceased in any of Addis Ababa hospitals. Then, verbal autopsy and hospital data sets were merged using the variables; full name of the deceased, sex, address, age, place and date of death. We calculated sensitivity, specificity and positive predictive values with 95% confidence interval. Results After merging, a total of 335 adult deaths were captured. For communicable diseases, the values of sensitivity, specificity and positive predictive values of verbal autopsy diagnosis were 79%, 78% and 68% respectively. For non-communicable diseases, sensitivity of the verbal autopsy diagnoses was 69%, specificity 78% and positive predictive value 79%. Regarding injury, sensitivity of the verbal autopsy diagnoses was 70%, specificity 98% and positive predictive value 83%. Higher sensitivity was achieved for HIV/AIDS and tuberculosis, but lower specificity with relatively more false positives. Conclusion These findings may indicate the potential of verbal autopsy to provide cost-effective information to guide policy on communicable and non communicable diseases double burden among adults in Ethiopia. Thus, a well structured verbal autopsy method, followed by qualified physician reviews could be capable of

Inpatient mortality is an indicator of the quality of care. We analyzed the mortality of under 5-year-old hospitalized children in the pediatric ward of Aristide Le Dantec Hospital for updating our data 10 years after our first study. We analyzed the data of the children hospitalized between 1 January and 31 December 2012. For each child, we collected anthropometric measurements converted to a z-score related to World Health Organization growth data. Logistic regression-generating models built separately with different anthropometric parameters were used to assess the risk of mortality according to children's characteristics. Data from 393 children were included. The overall mortality rate was 10% (39/393). Using logistic regression, the risk factors associated with death were severe wasting (odds ratio [OR]=8.27; 95% confidence interval [95% CI]) [3.79-18], male gender (OR=2.98; 95% CI [1.25-7.1]), dehydration (OR=5.4; 95% CI [2.54-13.43]) in the model using the weight-for-height z-score; male gender (OR=2.5; 95% CI [1.11-5.63]), dehydration (OR=8.43; 95% CI [3.83-18.5]) in the model using the height-for-age z-score; male gender (OR=2.7; 95% CI [1.19-6.24]), dehydration (OR=7.5; 95% CI [3.39-16.76]), severe deficit in the weight-for-age z-score (OR=2.4; 95% CI [1.11-5.63]) in the model using the weight-for-age z-score; and male gender (OR=2.5; 95% CI [1.11-5.63]) and dehydration (OR=8.43; 94% CI [3.83-18.5]) in the last model with mid-upper arm circumference (MUAC). Dehydration and malnutrition were two independent risk factors of death. The protocols addressing dehydration and malnutrition management should be audited and performed systematically for each child's anthropometric measurements at admission.

The 1997 BTS/RCP national audit of acute care of chronic obstructive pulmonary disease (COPD) found wide variations in mortality between hospitals which were only partially explained by known audit indicators of outcome. It was hypothesised that some of the unexplained variation may result from differences in hospital type, organisation and resources. This pilot study examined the hypothesis as a factor to be included in a future national audit programme. Thirty hospitals in England and Wales were randomly selected by geographical region and hospital type (teaching, large district general hospital (DGH), small DGH). Data on process and outcome of care (death and length of stay) were collected retrospectively at 90 days on all prospectively identified COPD admissions over an 8 week period. Each centre completed a questionnaire relating to organisation and resources available for the care of COPD patients. Eleven teaching hospitals, nine large DGHs, and 10 small DGHs provided data on 1274 cases. Mortality was high (14%) with wide variation between centres (IQR 9-19%). Small DGHs had a higher mortality (17.5%) than teaching hospitals (11.9%) and large DGHs (11.2%). When corrected for confounding factors, an excess of deaths in small DGHs was still observed (OR 1.56 (CI 1.04 to 2.35)) v teaching hospitals. Analysis of resource and organisational factors suggested higher mortality was associated with fewer doctors (OR 1.5) and with fewer patients being under the care of a specialist physician (OR 1.8). Small DGHs had fewest resources. Significant differences in mortality may exist between hospital types. The findings justify further study in a proposed national audit.

According to a widely accepted belief, we cannot know our own death-death means 'nothing' to us. At first sight, the meaning of 'nothing' just implies the negation or absence of 'something'. Death then simply refers to the negation or absence of life. As a consequence, however, death has no meaning

Mothers’ access to supportive hospital services after the loss of a baby through stillbirth or neonatal death

Full Text Available Every year, 3-5% of pregnant mothers in South Africa lose their babies to a stillbirth or neonatal death. These mothers need adequate services to prevent complications in their grieving process. Most of these babies are lost in hospital settings, so the treatment medical staff provide is vital. This study examined mothers’ experiences of accessing hospital, religious, formal and social services after a stillbirth or neonatal death. An exploratory research design was used to conduct applied research. A semi-structured interview schedule was used with a sample of 15 mothers who had lost a baby in the last 5 years. The findings were analysed quantitatively and qualitatively. The primary focus of this article is the quantitative findings relating to hospital services. The sample was small and these results cannot be generalised, but some conclusions are reached and recommendations are made to service providers in hospitals working with mothers who have lost babies. Mothers generally experienced the support services from hospitals as inadequate, compared to what hospitals could offer. Mothers that receive support after the loss of a baby generally cope better. This support thus assists them in the grieving process. Hospital staff can be trained to provide these services. Opsomming In Suid-Afrika verloor 3-5% swanger moeders hulle babas deur stilgeboorte of neonatale dood. Hierdie moeders benodig voldoende dienste om komplikasies in die rouproses te verhoed. Die behandeling deur mediese personeel is uiters belangrik omdat die meeste van dié babas in ‘n hospitaalopset sterf. Hierdie studie het moeders se ervarings van die toeganklikheid van hospitaal-, godsdienstige, formele en sosiale dienste na die dood van hulle babas deur stilgeboorte of neonatale dood ondersoek.

The body and ontology: Perinatal death and bereavement in the techno-scientific landscape of hospital care

Directory of Open Access Journals (Sweden)

Paul Richard Cassidy

2015-08-01

Full Text Available This study takes the body (of mother and child, the technoscientific hospital landscape and professional ritual as the locus of an endeavour to understand the embodied experience of perinatal death, in order to better comprehend how alternate understandings and ontologies of motherhood, personhood and bereavement emerge during care enactments.  Grounded in a descriptive and ethnographic approach the research analyses data from the entries of 22 members of a pregnancy loss support forum and 10 narrative style interviews. The research traces embodied experience from pregnancy, through diagnosis to the spatialised experience of the hospital, including the birth, postmortem contact and disposal of the corpse. Bounded by the sudden destruction of ontological security many of these women experience an existential crisis that results in a destructed stigmatised self. The research explores how overly medicalised obstetric care enacts understandings of perinatal death and bereavement that further problematizes postmortem relationships, creating toxic identities and embodied selves. Conversely, woman-centred midwifery that takes relational and social understandings as a basis for care can create the material conditions of possibility for a restoration of confidence in carnal self and a reconstruction of social bonds and order. Assembled through practice, discourse and policy, these bodies are individually, socially and politically enacted, but they are also multiple, mutable and enfolded assemblages of nature and culture. The research proposes that healthcare practice would benefit by considering natural stillbirths, just as contemporary obstetrics advocates natural childbirth.

vulnerabilities and inequity associated to health care access. Ischemic heart diseases will act as models for such assessment. OBJECTIVE: The present study investigates factors associated to the hospital death rate of patients admitted to hospital due to acute myocardial infarction (AMI and heart failure (HF, and whether admittance through Belo Horizonte Municipal Health Office (SMSA-BH Admission Center (AC was in any way associated to hospital death after adjustment of relevant factors. METHODS: Data obtained from the Hospital Admission Authorizations (AIH and requests for hospital beds at SMSA data base on latest hospital admissions based on AMI or HF diagnostic hypotheses. Multivariate analysis was conducted to investigate risk factors for hospital death. RESULTS: No association was found between hospital admittance access and hospital death risk from those causes. Multivariate analysis showed higher death risk for 60 and 60+ year-old patients (OR=2.9, AMI diagnostic hypothesis (OR=3.0, the need for ICU care (OR=1.6, females (OR=1.4, surgery type (OR=1.9, and public health service hospital (OR=3.5. Hospital admissions due to AMI on weekends also showed higher death risk for death (OR=1.7. CONCLUSION: Further investigation is necessary in order to evaluate the kind of medical assistance provided on weekends at public hospitals. Other hospital factors are to be taken into account, as well as patients and assistance procedures, as subsidies for proposals to ensure higher equity and quality standard for public health services.

Full Text Available Nosocomial fungal infections are gaining increased attention from infectiologists. An adequate investigation into the levels of airborne Aspergillus and other fungal spores in hospital settings, under normal conditions, is largely unknown. We monitored airborne spore contamination in a Swiss hospital building in order to establish a seasonally-dependent base-line level. Air was sampled using an impaction technique, twice weekly, at six different locations over one year. Specimens were seeded in duplicate on Sabouraud agar plates. Grown colonies were identified to genus levels. The airborne Aspergillus spore concentration was constantly low throughout the whole year, at a median level of 2 spores/m3 (inter-quartile range = IQR 1–4, and displayed no seasonal dependency. The median concentration of other fungal spores was higher and showed a distinct seasonal variability with the ambient temperature change during the different seasons: 82 spores/m3 (IQR 26–126 in summer and 9 spores/m3 (IQR 6–15 in winter. The spore concentration varied considerably between the six sampling sites in the building (10 to 26 spores/m3. This variability may explain the variability of study results in the literature.

Computed tomography (CT) plays a crucial role in early assessment of patients with traumatic brain injury (TBI). Marshall and Rotterdam are the mostly used scoring systems, in which CT findings are grouped differently. We sought to determine the scoring system and initial CT findings predicting the death at hospital discharge (early death) in patients with TBI. We included 245 consecutive adult patients with mild-to-severe TBI. Their initial CT and status at hospital discharge (dead or alive) were reviewed, and both CT scores were calculated. We examined whether each score was related to early death; compared the two scoring systems' performance in predicting early death, and identified the CT findings that are independent predictors of early death. More deaths occurred among patients with higher Marshall and Rotterdam scores (both P death (Marshall, AUC = 0. 85 vs. Rotterdam, AUC = 0.85). Basal cistern absence (odds ratio [OR] = 771.5, P death. Both Marshall and Rotterdam scoring systems can be used to predict early death in patients with TBI. The performance of the Marshall score is at least equal to that of the Rotterdam score. Thus, although older, the Marshall score remains useful in predicting patients' prognosis. Copyright © 2014 AUR. Published by Elsevier Inc. All rights reserved.

Many studies conducted to determine the attrition rate in Ethiopia have not compared attrition rates between hospitals and health centers in a relatively recent cohort of patients. This study compared death and loss to follow-up (LTFU rates among ART patients in hospitals and health centers in south Ethiopia. Methods: Data routinely collected from patients aged older than 15 years who started ART between July 2011 and August 2012 in 20 selected health facilities (12 being hospitals were analyzed. The outcomes of interest were LTFU and death. The data were entered, cleaned, and analyzed using Statistical Package for the Social Sciences version 20.0 and Stata version 12.0. Competing-risk regression models were used. Results: The service years of the facilities were similar (median 8 and 7.5 for hospitals and health centers, respectively. The mean patient age was 33.7±9.6 years. The median baseline CD4 count was 179 (interquartile range 93–263 cells/mm3. A total of 2,356 person-years of observation were made with a median follow-up duration of 28 (interquartile range 22–31 months; 24.6% were either dead or LTFU, resulting in a retention rate of 75.4%. The death rates were 3.0 and 1.5 and the LTFU rate were 9.0 and 10.9 per 100 person-years of observation in health centers and hospitals, respectively. The competing-risk regression model showed that the gap between testing and initiation of ART, body mass index, World Health Organization clinical stage, isoniazid prophylaxis

Early cell death detection with digital holographic microscopy.

Directory of Open Access Journals (Sweden)

Nicolas Pavillon

Full Text Available BACKGROUND: Digital holography provides a non-invasive measurement of the quantitative phase shifts induced by cells in culture, which can be related to cell volume changes. It has been shown previously that regulation of cell volume, in particular as it relates to ionic homeostasis, is crucially involved in the activation/inactivation of the cell death processes. We thus present here an application of digital holographic microscopy (DHM dedicated to early and label-free detection of cell death. METHODS AND FINDINGS: We provide quantitative measurements of phase signal obtained on mouse cortical neurons, and caused by early neuronal cell volume regulation triggered by excitotoxic concentrations of L-glutamate. We show that the efficiency of this early regulation of cell volume detected by DHM, is correlated with the occurrence of subsequent neuronal death assessed with the widely accepted trypan blue method for detection of cell viability. CONCLUSIONS: The determination of the phase signal by DHM provides a simple and rapid optical method for the early detection of cell death.

With over 1 million HIV-related deaths annually, quality end-of-life care remains a priority. Given strong public preference for home death, place of death is an important consideration for quality care. This 11 country study aimed to i) describe the number, proportion of all deaths, and demographics of HIV-related deaths; ii) identify place of death; iii) compare place of death to cancer patients iv), determine patient/health system factors associated with place of HIV-related death. In this retrospective analysis of death certification, data were extracted for the full population (ICD-10 codes B20-B24) for 1-year period: deceased's demographic characteristics, place of death, healthcare supply. i) 19,739 deaths were attributed to HIV. The highest proportion (per 1000 deaths) was for Mexico (9.8‰), and the lowest Sweden (0.2‰). The majority of deaths were among men (75%), and those aged <50 (69.1%). ii) Hospital was most common place of death in all countries: from 56.6% in the Netherlands to 90.9% in South Korea. The least common places were hospice facility (3.3%-5.7%), nursing home (0%-17.6%) and home (5.9%-26.3%).iii) Age-standardised relative risks found those with HIV less likely to die at home and more likely to die in hospital compared with cancer patients, and in most countries more likely to die in a nursing home. iv) Multivariate analysis found that men were more likely to die at home in UK, Canada, USA and Mexico; a greater number of hospital beds reduced the likelihood of dying at home in Italy and Mexico; a higher number of GPs was associated with home death in Italy and Mexico. With increasing comorbidity among people ageing with HIV, it is essential that end-of-life preferences are established and met. Differences in place of death according to country and diagnosis demonstrate the importance of ensuring a "good death" for people with HIV, alongside efforts to optimise treatment.

To assess the association of the anticholinergic medication burden with hospitalization and mortality in nursing home elderly patients and to investigate the role of coronary artery disease (CAD). Longitudinal (5-year) retrospective observational study. Nursing homes in Italy. A total of 3761 nursing home older residents. A comprehensive clinical and functional assessment was carried out through the interRAI long-term care facility instrument. The anticholinergic burden was assessed through the anticholinergic cognitive burden (ACB) scale. Occurrence of hospitalization/all-cause mortality was the primary composite outcome. First hospitalization and all-cause mortality were the secondary outcomes of the study. Hazard ratios (HRs) and subdistribution HRs were obtained through Cox and competing risk (death as competing event for hospitalization) models. Within the sample (mean age 83 ± 7 years; 72% females) the incidence rate of the primary outcome was 10/100 person-year. After adjusting for potential confounders and compared with participants with an ACB of 0, those with an ACB of 1 [HR 1.46; 95% confidence interval (CI) 1.12-1.90] and ABC of 2+ (HR 1.41; 95% CI 1.11-1.79) presented an increased risk of developing the primary outcome. After stratification, the risk for the primary outcome increased along with the anticholinergic burden, only for participants affected by CAD (HR 1.53; 95% CI 0.94-2.50 and HR 1.71; 95% CI 1.09-2.68 for the ACB of 1 and ACB of 2+ groups). An ACB score of 2+ was marginally associated with first hospitalization, considering death as a competing risk, only for those with CAD (subdistribution HR 3.47; 95% CI 0.99-12.3).

Although death anxiety is considered a universal phenomenon, attitudes toward death may vary across populations that differ in terms of religion and culture. Abdel-Khalek's Death Anxiety Scale (ASDA) was developed on the basis of the rationale that there are specific concepts related to death and after death in Muslim populations. This study aims to translate and adapt ASDA in the Turkish population, examine its validity and reliability, and to compare its psychometric properties with the widely used Templer's Death Anxiety Scale (DAS). A total of 220 medical students were included in the study. The Turkish version of ASDA, DAS, and Hospital Anxiety and Depression Scale were used for data collection. Cronbach's alpha coefficients were .86 for ASDA and .66 for DAS. Analysis by principal components with varimax rotation produced five factors for ASDA that explained 65.6% of total variance. ASDA and DAS were highly correlated with each other (r=.68, pASDA revealed better psychometric properties than DAS. This finding may reflect specific cultural and religious attitudes toward death or may result from more comprehensible language use in ASDA.

Full Text Available Abstract Background Although acute hospitals offer a twenty-four hour seven day a week service levels of staffing are lower over the weekends and some health care processes may be less readily available over the weekend. Whilst it is thought that emergency admission to hospital on the weekend is associated with an increased risk of death, the extent to which this applies to elective admissions is less well known. We investigated the risk of death in elective and elective patients admitted over the weekend versus the weekdays. Methods Retrospective statistical analysis of routinely collected acute hospital admissions in England, involving all patient discharges from all acute hospitals in England over a year (April 2008-March 2009, using a logistic regression model which adjusted for a range of patient case-mix variables, seasonality and admission over a weekend separately for elective and emergency (but excluding zero day stay emergency admissions discharged alive admissions. Results Of the 1,535,267 elective admissions, 91.7% (1,407,705 were admitted on the weekday and 8.3% (127,562 were admitted on the weekend. The mortality following weekday admission was 0.52% (7,276/1,407,705 compared with 0.77% (986/127,562 following weekend admission. Of the 3,105,249 emergency admissions, 76.3% (2,369,316 were admitted on the weekday and 23.7% (735,933 were admitted on the weekend. The mortality following emergency weekday admission was 6.53% (154,761/2,369,316 compared to 7.06% (51,922/735,933 following weekend admission. After case-mix adjustment, weekend admissions were associated with an increased risk of death, especially in the elective setting (elective Odds Ratio: 1.32, 95% Confidence Interval 1.23 to 1.41; vs emergency Odds Ratio: 1.09, 95% Confidence Interval 1.05 to 1.13. Conclusions Weekend admission appears to be an independent risk factor for dying in hospital and this risk is more pronounced in the elective setting. Given the planned

Physician call schedules are a critical element for medical practice and hospital efficiency. We compared readmission rates prior to and after a change in physician call system at Sunnybrook Health Sciences Centre. We studied patients discharged over a decade (2004 through 2013) and identified whether or not each patient was readmitted within the subsequent 28 days. We excluded patients discharged for a surgical, obstetrical, or psychiatric diagnosis. We used time-to-event analysis and time-series analysis to compare rates of readmission prior to and after the physician call system change (January 1, 2009). A total of 89,697 patients were discharged, of whom 10,001 (11%) were subsequently readmitted and 4280 died. The risk of readmission was increased by about 26% following physician call system change (9.7% vs 12.2%, P system change (95% confidence interval, 22%-31%; P system change persisted across patients with diverse ages, estimated readmission risks, and medical diagnoses. The net effect was equal to 7240 additional patient days in the hospital following call system change. A modest increase was observed at a nearby acute care hospital that did not change physician call system, and no increase in risk of death was observed with increased hospital readmissions. We suggest that changes in physician call systems sometimes increase subsequent hospital readmission rates. Further reductions in readmissions may instead require additional resources or ingenuity.

In this paper, we report our findings on radon survey in indoor environment which consists of around 105 rooms in 8 major hospitals in Shillong region and also present experimental estimates on the associated annual effective doses and life-time fatality risks. The survey has been undertaken using LR-115 Type 2 detectors. Radon activity concentration values were found to range from 65.66 Bq.m -3 to 783.77 Bq.m -3 with an arithmetic mean value of 260.4±138.3 Bq.m -3 and a geometric mean value of 228.4±1.67 Bq.m -3 . Distribution analysis of the radon activity concentration measured at the hospital rooms has been carried out. Of the total rooms surveyed, 60% have radon concentration more than the ICRP prescribed lower limit of 200 Bq.m -3 and about 4% of the rooms higher than the upper limit of 600 Bq.m -3 . Floor-wise study has been done and a decrease in radon concentration with increase in floor-number has been observed. (author)

PACS represents the future of radiology in modern hospitals. Workstations and databases can be developed to substantially increase clinician's productivity, improve diagnostic accuracy, and make a large amount of knowledge and patient information available on-line to the physician. Currently, there are several hospitals in the process of implementing a total PACS system. They include Madigan Army Medical Center (Tacoma, Washington), VA Hospital in Baltimore, and Hammersmith Hospital in London (1). In order to provide the radiologist, the clinicians, and other health personnel in Korea with the general concept of PACS and its up-to-date status report, we describe the MDIS system being implemented in MAMC (Madigan Army Medical Center) which is the first hospital-wide large-scale PACS in the world. The major PACS components in MAMC have been installed since March 1992 and the full system implementation will be completed by summer 1993. The goal of the MDIS system in MAMC is to increase to more than 90% filmless by the end of 1993. In this paper, we discuss the introduction and background of PACS and its potential benefits, the current status of PACS installation in MAMC and the future plan, and the flow of image data and text information in MAMC

Family members of patients who die in an ICU are at increased risk of psychological sequelae compared to those who experience a death in hospice. This study explored differences in rates and levels of complicated grief (CG), posttraumatic stress disorder (PTSD), and depression between family members of patients who died in an ICU versus a non-ICU hospital setting. Differences in family members' most distressing experiences at the patient's end of life were also explored. The study was an observational cohort. Subjects were next of kin of 121 patients who died at a large, Midwestern academic hospital; 77 died in the ICU. Family members completed measures of CG, PTSD, depression, and end-of-life experiences. Participants were primarily Caucasian (93%, N = 111), female (81%, N = 98), spouses (60%, N = 73) of the decedent, and were an average of nine months post-bereavement. Forty percent of family members met the Inventory of Complicated Grief CG cut-off, 31% met the Impact of Events Scale-Revised PTSD cut-off, and 51% met the Center for Epidemiologic Studies Depression Scale depression cut-off. There were no significant differences in rates or levels of CG, PTSD, or depressive symptoms reported by family members between hospital settings. Several distressing experiences were ranked highly by both groups, but each setting presented unique distressing experiences for family members. Psychological distress of family members did not differ by hospital setting, but the most distressing experiences encountered at end of life in each setting highlight potentially unique interventions to reduce distress post-bereavement for family members.

Mapping absolute tissue endogenous fluorophore concentrations with chemometric wide-field fluorescence microscopy

We report chemometric wide-field fluorescence microscopy for imaging the spatial distribution and concentration of endogenous fluorophores in thin tissue sections. Nonnegative factorization aided by spatial diversity is used to learn both the spectral signature and the spatial distribution of endogenous fluorophores from microscopic fluorescence color images obtained under broadband excitation and detection. The absolute concentration map of individual fluorophores is derived by comparing the fluorescence from "pure" fluorophores under the identical imaging condition following the identification of the fluorescence species by its spectral signature. This method is then demonstrated by characterizing the concentration map of endogenous fluorophores (including tryptophan, elastin, nicotinamide adenine dinucleotide, and flavin adenine dinucleotide) for lung tissue specimens. The absolute concentrations of these fluorophores are all found to decrease significantly from normal, perilesional, to cancerous (squamous cell carcinoma) tissue. Discriminating tissue types using the absolute fluorophore concentration is found to be significantly more accurate than that achievable with the relative fluorescence strength. Quantification of fluorophores in terms of the absolute concentration map is also advantageous in eliminating the uncertainties due to system responses or measurement details, yielding more biologically relevant data, and simplifying the assessment of competing imaging approaches.

recent studies have reported that hospitals have become a common place of death for nursing home residents. This study aimed to (i) measure variations in the proportion of in-hospital deaths across regions after adjustment for facility-level characteristics and (ii) identify environmental risk factors that might explain these variations in France. a cross-sectional retrospective survey was conducted in 2013. coordinating physicians in 3,705 nursing homes in France. a regression model was used to construct risk-adjusted rates of in-hospital deaths considering the facilities' characteristics. At the regional level, the outcome was defined as the difference between the observed rate of in-hospital deaths and the expected risk-adjusted rate. Values exceeding zero indicated rates that exceeded the national predicted rate of in-hospital deaths and thus highlighted regions in which the risk-adjusted probability for nursing home residents to die in a hospital was greater than average. among 70,119 nursing home decedents, 25.4% (n = 17,789) died in hospitals. The characteristics of the facilities had a significant influence on the proportion of in-hospital deaths among the nursing home decedents. However, after adjustment for these facility-level risk factors, the proportion of nursing homes that reported worse-than-average outcomes showed significant variation (range 26.0-79.6%). At the regional level, both the rate of acute hospital beds and the rate of general practitioners were found to be strongly correlated with the probability of reporting worse-than-average outcomes (P nursing home facilities. © The Author 2015.

Increased mast cell tryptase in sudden infant death - anaphylaxis, hypoxia or artefact?

Science.gov (United States)

1999-12-01

Increased concentrations of mast cell tryptase in post mortem blood have frequently been observed in sudden infant deaths but the cause of this has not yet been clarified. The aim was to evaluate factors (immunological, morphological and anamnestic data) behind the observed increase in mast cell tryptase in sudden infant deaths with elevated tryptase. Mast cell tryptase and total immunoglobulin (Ig) E were measured in post mortem sera from 44 infants younger than 1.5 years. Radioallergosorbent tests were performed for possible allergens (mixture for relevant food allergens, Phadiatop and latex). IgG subclasses, IgM, and complement factors (C3, C4 and factor B) were measured with radial immunodiffusion. Mast cells, labelled with antibodies against mast cell tryptase, were counted in the lungs and heart. The circumstances of death and medical history of the deceased infant and family were obtained through police and hospital records. In 40% of the SIDS cases tryptase was elevated (>10 microg/L). Total IgE in serum was increased in 33% compared with clinical reference values but showed no association with mast cell tryptase. RAST tests were positive in three cases. In one of these cases both tryptase and total IgE were elevated. The only variable that was associated with high tryptase values was prone position at death (P Children with elevated total IgE also displayed high concentrations of IgG1 and IgG2. Infants who died in the spring had significantly higher IgE than the others (P < or = 0.05). The results do not support the hypothesis that the elevated tryptase concentrations in sudden infant death are caused by allergy. The association between prone position at death and elevated tryptase could hypothetically be explained by mast cell degranulation due to, for example, a hypoxic stimulus in these infants.

The purpose of our study was to compare the intrapartum and early neonatal mortality rate of planned home birth with planned hospital birth in community midwife-led deliveries after case mix adjustment. The perinatal outcome of 679,952 low-risk women was obtained from the Netherlands Perinatal Registry (2000-2007). This group represents all women who had a choice between home and hospital birth. Two different analyses were performed: natural prospective approach (intention-to-treat-like analysis) and perfect guideline approach (per-protocol-like analysis). Unadjusted and adjusted odds ratios (ORs) were calculated. Case mix was based on the presence of at least one of the following: congenital abnormalities, small for gestational age, preterm birth, or low Apgar score. We also investigated the potential risk role of intended place of birth. Multivariate stepwise logistic regression was used to investigate the potential risk role of intended place of birth. Intrapartum and neonatal death at 0-7 days was observed in 0.15% of planned home compared with 0.18% in planned hospital births (crude relative risk 0.80, 95% confidence interval [CI] 0.71-0.91). After case mix adjustment, the relation is reversed, showing nonsignificant increased mortality risk of home birth (OR 1.05, 95% CI 0.91-1.21). In certain subgroups, additional mortality may arise at home if risk conditions emerge at birth (up to 20% increase). Home birth, under routine conditions, is generally not associated with increased intrapartum and early neonatal death, yet in subgroups, additional risk cannot be excluded.

The place of death of patients with cancer in Kuwait.

The place of death (PoD) has a significant effect on end-of-life care for patients dying of cancer. Little is known about the place of cancer deaths in our region. To identify the PoD of patients with cancer in Kuwait, we reviewed the death certificates submitted to the Kuwait Cancer Registry in 2009. Of 611 cancer deaths, 603 (98.7%) died in hospitals and only 6 (1%) patients died at home. More than half (57.3%) of inhospital deaths were in the Kuwait Cancer Control Center. Among those for whom the exact PoD within the hospital was identified (484 patients), 116 (24%) patients died in intensive care units and 12 (2.5%) patients died in emergency rooms. This almost exclusive inhospital death of patients with cancer in Kuwait is the highest ever reported. Research is needed to identify the reasons behind this pattern of PoD and to explore interventions promoting out-of-hospital death among terminally ill cancer patients in Kuwait.

Hypertensive disorder of pregnancy (HDP) is a major cause of maternal death. The goal of this study was to investigate factors associated with maternal death due to HDP. HDP-related maternal deaths in Japan reported to the Committee of the Ministry of Health, Labor and Welfare from 2010 to 2015 were examined. Out of 47 cases of HDP, 30 were identified as the major cause of maternal death. The median maternal age was 34 years (range 24-45) and the mortality in women aged ≥40 years was seven times higher that than in women aged deaths in Japan. Mothers aged ≥40 years are most at risk for HDP-related maternal death. Major concerns for preventabilities were late hospitalization, maternal transportation, and termination of pregnancy for term or near-term HDP. Regular vital checks and prompt lowering of BP were lacked during labor in most cases. HELLP syndrome should be managed at a general hospital with sufficient medical resources.

Implantable defibrillators (ICDs) prevent sudden cardiac death. With declining health, ICD therapy may prolong death and expose the patient to unnecessary pain and anxiety. Few studies have addressed end of life care in ICD patients. The objective of this study was to investigate end of life in ICD patients, with respect to location of death; duration between do-not-resuscitate (DNR)-orders and deactivation of ICD therapy or DNR and time of death. A descriptive analysis of 65 deceased ICD patients, all whom had a written DNR-order before death, is presented. The majority (86%) was treated in hospitals, mainly (63%) university hospitals, and many (33%) in cardiology wards. Despite DNR-order, ICD shock therapy was active in 51% of all patients. In those with therapy deactivated at death, therapy deactivation was carried out two days or more after DNR-order in more than a third (38%). The time from DNR decision to death in patients with therapy active had a median of four days (IQR 1-38). During the last 24h of life, 24% of the patients experienced shock treatment. The majority of ICD patients with a DNR-order were treated in university hospitals. More than half still had shock treatment active at time of death with a median of four days or more between DNR decision and death. Patients with therapy deactivated, two days or more elapsed in more than a third from DNR decision to deactivation of therapy, exposing patients to a high risk of painful shocks before death.

Few studies on colorectal cancer look at the one-third of patients for whom treatment fails and who need a management strategy for death. This paper has examined the mode and place of death in patients with colorectal cancer. This study was a review of 209 deaths, analysed between January 2001 and September 2004 by retrospective review of a prospectively collected database. A total of 118 patients (group 1) had undergone resection of their primary colorectal cancer, 20 (group 2) had had a defunctioning stoma or bypass surgery and the remaining 71 patients (group 3) had either had no surgery, an open and close laparotomy or had a colonic stent. One hundred and fifty-six (75%) patients died of colorectal cancer with the remainder dying of other causes. The number of admissions to hospital and the number of days spent in hospital from diagnosis to death were greatest in group 1. Overall, only 34 patients (22%) dying from colorectal cancer died at home. Forty (26%) died in hospital and 70 (45%) died in a palliative care unit. Patients dying from colorectal cancer who undergo surgical resection of their primary tumour spend more time between diagnosis and death in hospital. They are also more likely to die in hospital than patients treated by surgical palliation or nonsurgically. Patients who are treated palliatively from the outset (group 3) are most likely to die at home. If hospital is accepted as an appropriate place for death from colorectal cancer, then greater provision for this should be made.

Numerous studies have reported the presence of temporal variations in biological processes. Seasonal variation (SV) in stroke has been widely studied, but little data have been published on this phenomenon in the Southern Hemisphere, and there have been no studies reported from Argentina. The goals of the present study were to describe the SV of admissions and deaths for stroke and examine trends in stroke morbidity and mortality over a 3-year period in a community hospital in Argentina. Hospital discharge reports from the electronic database of vital statistics between 1999 and 2001 were examined retrospectively. Patients who had a main discharge diagnosis of stroke (ischemic or hemorrhagic) or cerebrovascular accident (International Classification of Diseases, Ninth Revision codes 431, 432, 434, and 436) were selected. The study sample included 1382 hospitalizations by stroke (3.5% of all admissions). In-hospital mortality demonstrated a winter peak (25.5% vs 17% in summer; P = .001). The crude seasonal stroke attack rate (ischemic and hemorrhagic) was highest in winter (164 per 100,000 population; 95% CI, 159-169 per 100,000) and lowest in summer (124 per 100,000; 95% CI, 120-127 per 100,000; P = .008). Stroke admissions followed a seasonal pattern, with a winter-spring predominance (P = .008). Our data indicate a clear SV in stroke deaths and admissions in this region of Argentina. The existence of SV in stroke raises a different hypothesis about the rationale of HF admissions and provides information for the organization of care and resource allocation.

McCullough, Peter A; Fallahzadeh, Mohammad Kazem; Hegazi, Refaat M

2016-01-01

There is an expanding prevalence pool of heart failure (HF) due to the increasing prevalence of survivors of myocardial infarction, diabetes, hypertension, chronic kidney disease, and obesity. There is increasing interest in the role of nutrition in all forms of HF, given observations concerning micro- and macronutrient deficiencies, loss of lean body mass or sarcopenia, and their relationships with hospitalization and death. This review examines the relationships among loss of lean body mass, macro- and micronutrient intake, and the natural history of HF, particularly in the elderly, in whom the risks for all-cause rehospitalization, infection, falls, and mortality are increased. These risks are potentially modifiable through strategies that improve nutrition in this vulnerable population.

Progressive concentric (centripetal) loss of vision is one pattern of visual field loss in retinitis pigmentosa. This study provides the first clinicopathologic correlations for this form of retinitis pigmentosa. A family with autosomal dominant concentric retinitis pigmentosa was examined clinically and with visual function tests. A post-mortem eye of an affected 94 year old family member was processed for histopathology and immunocytochemistry with retinal cell specific antibodies. Unrelated simplex/multiplex patients with concentric retinitis pigmentosa were also examined. Affected family members of the eye donor and patients from the other families had prominent peripheral pigmentary retinopathy with more normal appearing central retina, good visual acuity, concentric field loss, normal or near normal rod and cone sensitivity within the preserved visual field, and reduced rod and cone electroretinograms. The eye donor, at age 90, had good acuity and function in a central island. Grossly, the central region of the donor retina appeared thinned but otherwise normal, while the far periphery contained heavy bone spicule pigment. Microscopically the central retina showed photoreceptor outer segment shortening and some photoreceptor cell loss. The mid periphery had a sharp line of demarcation where more central photoreceptors were near normal except for very short outer segments and peripheral photoreceptors were absent. Rods and cones showed abrupt loss of outer segments and cell death at this interface. It is concluded that concentric retinitis pigmentosa is a rare but recognizable phenotype with slowly progressive photoreceptor death from the far periphery toward the central retina. The disease is retina-wide but shows regional variation in severity of degeneration; photoreceptor death is severe in the peripheral retina with an abrupt edge between viable and degenerate photoreceptors. Peripheral to central gradients of unknown retinal molecule(s) may be defective

While health care services are beginning to implement system-wide patient safety interventions, evidence on the efficacy of these interventions is sparse. We know that uptake can be variable, but we do not know the factors that affect uptake or how the interventions establish change and, in particular, whether they influence patient outcomes. We conducted a systematic review to identify how organisational and cultural factors mediate or are mediated by hospital-wide interventions, and to assess the effects of those factors on patient outcomes. A systematic review was conducted and reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Database searches were conducted using MEDLINE from 1946, CINAHL from 1991, EMBASE from 1947, Web of Science from 1934, PsycINFO from 1967, and Global Health from 1910 to September 2012. The Lancet, JAMA, BMJ, BMJ Quality and Safety, The New England Journal of Medicine and Implementation Science were also hand searched for relevant studies published over the last 5 years. Eligible studies were required to focus on organisational determinants of hospital- and system-wide interventions, and to provide patient outcome data before and after implementation of the intervention. Empirical, peer-reviewed studies reporting randomised and non-randomised controlled trials, observational, and controlled before and after studies were included in the review. Six studies met the inclusion criteria. Improved outcomes were observed for studies where outcomes were measured at least two years after the intervention. Associations between organisational factors, intervention success and patient outcomes were undetermined: organisational culture and patient outcomes were rarely measured together, and measures for culture and outcome were not standardised. Common findings show the difficulty of introducing large-scale interventions, and that effective leadership and clinical champions, adequate

The purpose of this study was to determine the relationship between urinary cotinine and total 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) concentrations in non-smoking staff and the indoor levels of fine particles (PM 2.5 ) in hospitality venues that allow smoking, with respect to demographic and indoor environmental factors. We evaluated 62 hospitality venues that allowed smoking in Seoul, Korea. A real-time aerosol monitor was used to measure indoor PM 2.5 concentrations. Field technicians recorded indoor environmental characteristics. One non-smoking staff member in each hospitality venue was tested for urinary cotinine and total NNAL concentrations. Demographic characteristics were obtained from self-reported staff questionnaires. Natural-log (ln)-transformed PM 2.5 concentrations were significantly correlated with the ln-transformed cotinine ( r = 0.31) and the total NNAL concentrations ( r = 0.32). In multivariable regression analysis, the urinary cotinine concentrations of the staff members were significantly correlated with indoor PM 2.5 concentrations; those with the highest concentrations were more likely to be women or staff members that worked in venues with a volume hospitality venues that allow smoking.

Our previous meta-analysis found that South Asians and Blacks in the UK were at a substantially increased risk of hospital admission from asthma. These estimates were, however, derived from pooling data from a limited number of now dated studies, confined to only three very broad ethnic groups (i.e. Whites, South Asians and Blacks) and failed to take account of possible sex-related differences in outcomes within these ethnic groups. We undertook the first study investigating ethnic variations in asthma outcomes across an entire population. This retrospective 9-year cohort study linked Scotland's hospitalisation/death records on asthma to the 2001 census (providing ethnic group). We calculated age, country of birth and Scottish Index of Multiple Deprivation adjusted incident rate ratios (IRRs) for hospitalisation or death by sex for the period May 2001-2010. We calculated hazard ratios (HRs) for asthma readmission and subsequent asthma death. We were able to link data on 4.62 million people (91.8% of the Scottish population), yielding over 38 million patient-years of data, 1,845 asthma deaths, 113,795 first asthma admissions, and 107,710 readmissions (40,075 of which were for asthma). There were substantial ethnic variations in the rate of hospitalisation/death in both males and females. When compared to the reference Scottish White population, the highest age-adjusted rates were in Pakistani males (IRR = 1.59; 95% CI, 1.30-1.94) and females (IRR = 1.50; 95% CI, 1.06-2.11) and Indian males (IRR = 1.34; 95% CI, 1.16-1.54), and the lowest were seen in Chinese males (IRR = 0.62; 95% CI, 0.41-0.94) and females (IRR = 0.49; 95% CI, 0.39-0.61). There are very substantial ethnic variations in hospital admission/deaths from asthma in Scotland, with Pakistanis having the worst and Chinese having the best outcomes. Cultural factors, including self-management and health seeking behaviours, and variations in the quality of primary care provision are the most

2015-10-01

In South Korea, nationwide surveillance for severe fever with thrombocytopenia syndrome (SFTS) began during 2013. Among 301 surveillance cases, 35 hospitalized case-patients in 25 areas were confirmed by using virologic testing, and 16 (46%) case-patients subsequently died. The SFTS cases occurred during May-November and peaked during June (9 cases, 26%). The incidence of SFTS was higher in the southern regions of South Korea. Age and neurologic symptoms, including decreased level of consciousness and slurred speech, were heavily associated with death; neurologic symptoms during the first week after disease onset were also associated with death. Although melena was common among patients who died, no other hemorrhagic manifestations were substantively more common among those who died. No effective treatments, including ribavirin, were identified. Expansion of SFTS surveillance to include the outpatient sector and development of an antibody test would enhance completeness of SFTS detection in South Korea.

This study examined the coding validity of hypertension, diabetes, obesity and depression related to the presence of their co-existing conditions, death status and the number of diagnosis codes in hospital discharge abstract database. We randomly selected 4007 discharge abstract database records from four teaching hospitals in Alberta, Canada and reviewed their charts to extract 31 conditions listed in Charlson and Elixhauser comorbidity indices. Conditions associated with the four study conditions were identified through multivariable logistic regression. Coding validity (i.e. sensitivity, positive predictive value) of the four conditions was related to the presence of their associated conditions. Sensitivity increased with increasing number of diagnosis code. Impact of death on coding validity is minimal. Coding validity of conditions is closely related to its clinical importance and complexity of patients' case mix. We recommend mandatory coding of certain secondary diagnosis to meet the need of health research based on administrative health data.

to implement, hospital wide electronic medical records (EMRs) with varying degrees of functionality. Few hospitals have implemented a complete end-to-end digital system with the ability to bring about major transformation in clinical care. Although the many challenges in implementing EMRs have been well documented, they have not been incorporated into an evidence-based, field-tested checklist that can practically assist hospitals in preparing for EMR implementation as both a technical innovation and a vehicle for major digital transformation of care. What does this paper add? This paper outlines a 19-question checklist that was developed using a formal methodological framework comprising literature review of relevant issues, proceedings from an interactive workshop involving a multidisciplinary group of digital leads from hospitals throughout Queensland, including three hospitals undertaking EMR implementation and one hospital with complete end-to-end EMR, and review of a draft checklist by senior clinical leads within a statewide digital healthcare improvement network. The checklist distinguishes between issues pertaining to EMR as a technical innovation and EMR as a vehicle for digital transformation of patient care. What are the implications for practitioners? Successful implementation of a hospital-wide EMR requires senior managers, clinical leads, information technology teams and project management teams to fully address key operational and strategic issues. Using an issues checklist may help prevent any one issue being inadvertently overlooked or underemphasised in the planning and implementation stages, and ensure the EMR is fully adopted and optimally used by clinician users in an ongoing digital transformation of care.

Although most patients express a preference to die at home, many (over 30 percent) still die in hospital. This study's purpose was to explore the experience of hospital death from the perspective of patients' family members. interviews were conducted with family members of patients who had died at hospitals affiliated with a large tertiary referral centre in the United States. Content analysis was used to analyze findings. We interviewed 30 family members by phone. Themes were arranged by time frame: before death, time of death, and after death. Families do not interpret clinical cues leading up to death in the same way healthcare providers do; families need clear and direct explanations from providers. Clinicians should assess patient and family understandings of prognosis and communicate clearly and directly. Family members value being with their loved one at the time of death, and they value spending time with the body after death; this should be facilitated in clinical practice.

Exchange-biased GMR sensors were employed for biodetection using a DC in-plane measuring method and a magnetic label of Fe{sub 3}O{sub 4} microspheres. It was revealed that an ultra-wide concentration span covering five orders from 10 ng/mL to 1000 μg/mL was achieved in a home-made biodetection device. The concentration x dependence of output voltage difference |ΔV| between with and without magnetic labels, exhibits nonlinear futures, which undergoes two functions depending on the concentration region. For the low concentration region from 10 ng/mL to 10 μg/mL, a logarithmic relation of |ΔV|=26.3lgx+91.4 fits well, while for the high concentration region, a negative exponential function of |ΔV|=3113(1−e{sup −x/250}) describes the |ΔV|~x relation better. For the former, the “coffee ring” effect, formed during the solvent evaporation, was considered as the main reason for the nonlinear relation. While for the latter with high concentration, the overlap among the particles and the enhanced interaction of the magnetic dipole were responsible for the nonlinear |ΔV|~x relationship. Moreover, the calculated detectable concentration limit is agreed well with the experimental data. - Highlights: • Ultra-wide concentration span covering five orders from 0.01 to 1000 μg/mL. • A logarithmic function well describes the relation of |ΔV|~x at low concentration. • An exponential function well describes the relation of |ΔV|~x at high concentration.

Background: A substantial number of cancer patients receive chemotherapy until the end of life (EoL). Various factors have been shown to be associated with receipt of chemotherapy until near death. In this study, we determine our average time from last chemotherapy to death (TLCD) and explore different factors that may be associated with decreased TLCD. Materials and Methods: A retrospective review of medical records of adult cancer patients who received chemotherapy during their illness and died in our hospital between January 2010 and January 2012 was conducted. Chi-square test and t-test were used to examine the correlation between selected factors and use of chemotherapy within 60 days of death. Multivariate analysis was used to test independent significance of factors testing positive in univariate analysis. Kaplan-Meier method was used to perform survival analysis. Results: Of the 115 cancer patients who died in the hospital, 41 (35.6%) had TLCD of 60 days or less. Patients with better performance status and those dying under medical oncology service were more likely to be in this group of patients. Univariate analysis showed that these patients were less likely to have palliative care involvement, were more likely to die of treatment related causes, and more likely to have died in the Intensive Care Unit. Multivariate analysis confirmed lack of palliative care involvement and better performance status as independent factors for TLCD less than 60 days. Survival analyses showed that patients with palliative care involvement and those dying under palliative care service were likely to have significantly longer TLCD. Conclusions: Cancer patients who have no involvement of palliative care team in their management tend to receive chemotherapy near the EoL, have more aggressive EoL care, and have higher risk of dying die from treatment related complications. Palliative care should be involved early in the care of cancer patients. PMID:25810576

Analyze trends in hospital cost and revenue, as well as price and quantity (1994-2005) as a function of health maintenance organization (HMO) penetration, HMO concentration, and for-profit (FP) HMO market share. Medicare hospital cost reports, AHA Annual Surveys, HMO data from Interstudy, and other supplemental data. A retrospective study of all short-term, general, nonfederal hospitals in metropolitan statistical areas (MSAs) in the United States from 1994 to 2005, using hospital/MSA fixed-effects translog regression models. A 10 percentage point increase in HMO enrollment is associated with 4.1-4.2 percent reduction in costs and revenues in the pre-2000 period but only a 2.1-2.5 percent reduction in the post-2000 period. Hospital revenue in HMO-dominant markets (highly concentrated HMO market and competitive hospital market) is 19-27 percent lower than other types of markets, and the difference is most likely due mainly to lower prices and to a lesser extent lower utilization. The historical difference of lower spending in high HMO penetration markets compared with low HMO markets narrowed after 2000 and the relative concentration between HMO and hospital markets can substantially influence hospital spending. Additional research is needed to understand how different aspects of these two markets have changed and interacted and how they are causally linked to spending trends.

Esophagectomy, one of the most invasive of all gastrointestinal operations, is associated with a high frequency of postoperative complications and in-hospital mortality. The purpose of the present study was to determine whether exposure to the atomic bomb explosion at Hiroshima in 1945 might be a preoperative risk factor for in-hospital mortality after esophagectomy in esophageal cancer patients. We thus reviewed the outcomes of esophagectomy in 31 atomic bomb survivors with esophageal cancer and 96 controls (also with cancer but without atomic bomb exposure). We compared the incidences of postoperative complications and in-hospital mortality. Of the clinicopathological features studied, mean patient age was significantly higher in atomic bomb survivors than in controls. Of the postoperative complications noted, atomic bomb survivors experienced a longer mean period of endotracheal intubation and higher incidences of severe pulmonary complications, severe anastomotic leakage, and surgical site infection. The factors associated with in-hospital mortality were exposure to the atomic bomb explosion, pulmonary comorbidities, and electrocardiographic abnormalities. Multivariate analysis revealed that exposure to the atomic bomb explosion was an independent significant preoperative risk factor for in-hospital mortality. Exposure to the atomic bomb explosion is thus a preoperative risk factor for in-hospital death after esophagectomy to treat esophageal cancer. © 2013 Wiley Periodicals, Inc. and the International Society for Diseases of the Esophagus.

Levine, B; Green, D; Smialek, J E

1995-09-01

The purpose of this study was to evaluate the role of ethanol in deaths due to heroin intoxication. Over a 12 month period, all cases investigated by the Office of the Chief Medical Examiner, State of Maryland where a blood screen by Roche Abuscreen radioimmunoassay (RIA) was positive at a cutoff of 100 ng/mL were included in the study. Free morphine was quantitated using the Coat-A-Count RIA and ethanol was quantitated by head space gas chromatography. All presumptive morphine positive cases were confirmed by gas chromatography/mass spectrometry. Seventy of the 119 cases where death was attributed to narcotic or alcohol and narcotic intoxication had blood ethanol concentrations (BAC) greater than or equal to 0.02 g/dL; 48 had BAC > or = 0.10 g/dL. Only 3 of 45 cases where morphine was identified but was unrelated to death had BAC > or = 0.02 g/dL. At all ranges of free morphine concentrations, there was a greater percentage of narcotic deaths when ethanol was present. From the data, we conclude that 1) the use of even small amounts of ethanol with heroin is clearly a risk factor in deaths due to heroin, 2) there are some heroin deaths where no free morphine is identified in the blood. In these deaths, ethanol is unlikely to be present, 3) at blood ethanol concentrations between 0.20 and 0.29 g/dL, the morphine concentrations in heroin deaths increased significantly, 4) at blood ethanol concentrations greater than 0.30 g/dL, morphine became less of a factor than the ethanol in causing death.

Factors predictive for death from snake envenomation vary between studies, possibly due to variation in host genetic factors and venom composition. This study aimed to evaluate predictive factors for death from snake envenomation in Myanmar. A prospective study was performed among adult patients with snakebite admitted to tertiary hospitals in Yangon, Myanmar, from May 2015 to August 2016. Data including clinical variables and laboratory parameters, management, and outcomes were evaluated. Multivariate regression analysis was performed to evaluate factors predictive for death at the time of presentation to the hospital. Of the 246 patients with snake envenomation recruited into the study, 225 (92%) survived and 21 (8%) died during hospitalization. The snake species responsible for a bite was identified in 74 (30%) of the patients; the majority of bites were from Russell's vipers (63 patients, 85%). The independent factors predictive for death included 1) duration from bite to arrival at the hospital >1 h (odds ratio [OR]: 9.0, 95% confidence interval [CI]: 1.1-75.2; P=0.04); 2) white blood cell counts >20 ×10 3 cells·μL -1 (OR: 8.9, 95% CI: 2.3-33.7; P=0.001); and 3) the presence of capillary leakage (OR: 3.7, 95% CI: 1.2-11.2; P=0.02). A delay in antivenom administration >4 h increases risk of death (11/21 deaths). Patients who present with these independent predictive factors should be recognized and provided with early appropriate intervention to reduce the mortality rate among adults with snake envenomation in Myanmar.

Full Text Available China is facing a dramatic aging of its population. Little is known about the factors that influence the place of death and the trends in the place of death for elderly people in China. The purposes of this study were: (1 to examine the impact of the socioeconomic status (SES on place of death for elderly Chinese residents; and (2 to assess temporal trends in the place of death over the last 15 years. Data were derived from the Chinese Longitudinal Healthy Longevity Survey (CLHLS (1998–2012. Place-of-death as an outcome was dichotomized into either death at home or death outside the home. Logistic regression analyses were used to examine the impact of SES on place of death. The results showed that, of the 23,098 deaths during the study period, 87.78% occurred at home. The overall trend in home death has increased since 2005. SES was shown to be an important factor affecting place of death. The elderly with higher SES were more likely to die where health resources were concentrated, i.e., in a hospital or other type of institution. Our finding suggests that the trend towards a greater emphasis on death at home may call for the development of more supportive home care programs in China. Our finding also suggests that the socioeconomic differences in the place of death may be related to the availability of or access to health care services.

Introduction Although death anxiety is considered a universal phenomenon, attitudes toward death may vary across populations that differ in terms of religion and culture. Abdel-Khalek’s Death Anxiety Scale (ASDA) was developed on the basis of the rationale that there are specific concepts related to death and after death in Muslim populations. This study aims to translate and adapt ASDA in the Turkish population, examine its validity and reliability, and to compare its psychometric properties with the widely used Templer’s Death Anxiety Scale (DAS). Methods A total of 220 medical students were included in the study. The Turkish version of ASDA, DAS, and Hospital Anxiety and Depression Scale were used for data collection. Results Cronbach’s alpha coefficients were .86 for ASDA and .66 for DAS. Analysis by principal components with varimax rotation produced five factors for ASDA that explained 65.6% of total variance. ASDA and DAS were highly correlated with each other (r=.68, pASDA revealed better psychometric properties than DAS. This finding may reflect specific cultural and religious attitudes toward death or may result from more comprehensible language use in ASDA. PMID:28360742

Full Text Available Abstract Background Many health care systems now use priority wait lists for scheduling elective coronary artery bypass grafting (CABG surgery, but there have not yet been any direct estimates of reductions in in-hospital mortality rate afforded by ensuring that the operation is performed within recommended time periods. Methods We used a population-based registry to identify patients with established coronary artery disease who underwent isolated CABG in British Columbia, Canada. We studied whether postoperative survival during hospital admission for CABG differed significantly among patients who waited for surgery longer than the recommended time, 6 weeks for patients needing semi-urgent surgery and 12 weeks for those needing non-urgent surgery. Results Among 7316 patients who underwent CABG, 97 died during the same hospital admission, for a province-wide death rate at discharge of 1.3%. The observed proportion of patients who died during the same admission was 1.0% (27 deaths among 2675 patients for patients treated within the recommended time and 1.5% (70 among 4641 for whom CABG was delayed. After adjustment for age, sex, anatomy, comorbidity, calendar period, hospital, and mode of admission, patients with early CABG were only 2/3 as likely as those for whom CABG was delayed to experience in-hospital death (odds ratio 0.61; 95% confidence interval [CI] 0.39 to 0.96. There was a linear trend of 5% increase in the odds of in-hospital death for every additional month of delay before surgery, adjusted OR = 1.05 (95% CI 1.00 to 1.11. Conclusion We found a significant survival benefit from performing surgical revascularization within the time deemed acceptable to consultant surgeons for patients requiring the treatment on a semi-urgent or non-urgent basis.

Full Text Available BACKGROUND The voluntary eye donation is still the most popular methods of eye donation in our country. Since last three decades, the voluntary eye donation is promoted by a number of NGOs and Government of India. The meaning of voluntary eye donation is that an individual has prior knowledge about eye donation and also has the contact number of the eye bank. When they come across any death in their community, they will contact the eye bank for eye donation. As per Eye Bank Association of India, the incidence of total blindness is 8.9 million and 1% of this is corneal blindness. Each year, 25,000 to 30,000/new corneal blind patients are added. The voluntary eye donation is not sufficient in providing transplantable corneas to the corneal blind. As our concentration is mainly on voluntary eye collections, this is one of the main reasons that we are unable reach our target of sight restoration in the management of corneal blindness. In this study, we have analysed the voluntary eye donations procured from residence and hospital. The aim of the study is to compare corneas procured by hospital eye donations and residence eye donations to look into all factors that contribute to a transplantable cornea. MATERIALS AND METHODS The donor corneas retrieved from the year 2005-2010 were analysed. The hospital eye donations and residential eye donations were divided into two study groups. The factors analysed were number of corneas collected, donor age and gender, serology test result, death to preservation time (DPT, optical grade cornea, utilisation of corneas for transplantation and role of pledging in eye donation. Study Type- Retrospective study. Study Done- At Lions International Eye Bank, Bangalore. RESULTS The total number of donor eyes collected from the year 2005-2010 were 7362 of which residence collections was 50.73% and hospital collections was 49.26%. The 5-year period between from 2005 to 2010 in spite of not conducting a Hospital Cornea

ED overcrowding has been associated with increased mortality, morbidity and delays to essential treatment. It was hypothesised that hospital-wide reforms designed to improve patient access and flow, in addition to improving ED overcrowding, would impact on clinically important processes within the ED, such as timely delivery of antibiotics. A single pre-implementation and post-implementation prospective cohort study was conducted prior to and after a hospital-wide reform (Timely Quality Care (TQC)). Among patients who had intravenous antibiotics prescribed in the ED, data were prospectively collected on times of presentation, prescription and administration of antibiotics. Demographics and discharge diagnoses were retrospectively extracted. There were 380 cases included with 179 cases prior to introduction of the TQC model and 201 cases after its introduction. Time from presentation to administration of antibiotics improved significantly from 192 (99-320) min to 142 (81-209) min (P antibiotics were significantly reduced. These findings suggest that improved quality of care in this area may be achieved with processes aimed at improved hospital access and flow. Ongoing evaluation and vigilance is necessary to ensure sustainability and drive further improvements. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

In this study, we investigated caregiver's death representation in hospice. The results presented here are a further analysis of the data collected in our previous study, concerning the evaluation of the caregiver in hospice. The data analysis of 24 caregivers of patients hospitalized in Rimini Hospice (Italy) underlined that caregivers avoiding death representation of the patient admitted to hospice had fewer protective factors (52.3%) and more risk factors (47.7%) than caregivers nonavoiding (66.5% and 33.5%, respectively). Caregivers avoiding death representation, moreover, experienced a greater distress (58%) than those nonavoiding (42%).

Objectives To monitor the early effect of a national population screening programme for abdominal aortic aneurysm in 65-year-old men. Setting The study used national statistics for death rates from abdominal aortic aneurysm (Office of National Statistics) and hospital admission data in England (Hospital Episode Statistics). Methods Information concerning deaths from abdominal aortic aneurysm (ruptured and non-ruptured) (1999-2014) and hospital admissions for ruptured abdominal aortic aneurysm (2000-2015) was examined. Results The absolute number of deaths from abdominal aortic aneurysm in men and women aged 65 and over has decreased by around 30% from 2001 to 2014, but as the population has increased, the relative reduction was 45.6% and 40.0%, respectively. Some 65% of all abdominal aortic aneurysm deaths are in men aged over 65; women aged 65 and over account for around 31%. Deaths from ruptured abdominal aortic aneurysm in men aged 60-74 (the screened group) appear to be declining at the same rate as in men aged 75 and over. The relative decline in admissions to hospital with ruptured abdominal aortic aneurysm may be greater in men and women aged 60-74 (which contains the screened group of men), than those older, giving the first possible evidence that abdominal aortic aneurysm screening is having an effect. Conclusion The death rate from abdominal aortic aneurysm is declining rapidly in England. There is the first evidence that screening may be contributing to this reduction.

To examine the association between hospital-local health department (LHD) collaboration around community health needs assessments (CHNAs) and hospital investment in community health. We combined 2015 National Association of County and City Health Officials (NACCHO) Forces of Change, 2013 NACCHO Profile, and 2014-2015 Area Health Resource File data to identify a sample of LHDs (n = 439) across the United States. We included data on hospitals' community benefit from their 2014 tax filings (Internal Revenue Service Form 990, Schedule H). We used bivariate and multivariate regression analyses to examine LHDs' involvement in hospitals' CHNAs and implementation strategies and the relationship with hospital investment in community health. The LHDs that collaborated with hospitals around CHNAs were significantly more likely to be involved in joint implementation planning activities than were those that did not. Importantly, LHD involvement in hospitals' implementation strategies was associated with greater hospital investment in community health improvement initiatives. Joint CHNAs may improve coordination of community-wide health improvement efforts between hospitals and LHDs and encourage hospital investment in community health improvement activities. Public Health Implications. Policies that strengthen LHD-hospital collaboration around the CHNA may enhance hospital investments in community health.

To assess the effect of routinely delivered home-based end-of-life care on hospital use at the end of life and place of death. Retrospective analysis using matched controls and administrative data. Community-based care in England. 29,538 people aged over 18 who received Marie Curie nursing support compared with 29,538 controls individually matched on variables including: age, socioeconomic deprivation, prior hospital use, number of chronic conditions and prior diagnostic history. Home-based end-of-life nursing care delivered by the Marie Curie Nursing Service (MCNS), compared with end-of-life care available to those who did not receive MCNS care. Proportion of people who died at home; numbers of emergency and elective inpatient admissions, outpatient attendances and attendances at emergency departments in the period until death; and notional costs of hospital care. Intervention patients were significantly more likely to die at home and less likely to die in hospital than matched controls (unadjusted OR 6.16, 95% CI 5.94 to 6.38, pnursing for longer. Home-based end-of-life care offers the potential to reduce demand for acute hospital care and increase the number of people able to die at home.

Maeda, Shoichi; Starkey, Jay; Kamishiraki, Etsuko; Ikeda, Noriaki

2013-12-01

In Japan, physicians are required to report unexpected health care-associated patient deaths to the police. Patients needing to be transferred to another institution often have complex medical problems. If a medical error occurs, it may be either at the final or the referring institution. Some fear that liability will fall on the final institution regardless of where the error occurred or that the referring facility may oppose such reporting, leading to a failure to report to police or to recommend an autopsy. Little is known about the actual opinions of physicians and risk managers in this regard. The authors sent standardised, self-administered questionnaires to all hospitals in Japan that participate in the national general residency program. Most physicians and risk managers in Japan indicated that they would report a patient's death to the police where the patient has been transferred. Of those who indicated they would not report to the police, the majority still indicated they would recommend an autopsy

Moriya, Asako S; Vogt, William B; Gaynor, Martin

2010-10-01

There has been substantial consolidation among health insurers and hospitals, recently, raising questions about the effects of this consolidation on the exercise of market power. We analyze the relationship between insurer and hospital market concentration and the prices of hospital services. We use a national US dataset containing transaction prices for health care services for over 11 million privately insured Americans. Using three years of panel data, we estimate how insurer and hospital market concentration are related to hospital prices, while controlling for unobserved market effects. We find that increases in insurance market concentration are significantly associated with decreases in hospital prices, whereas increases in hospital concentration are non-significantly associated with increases in prices. A hypothetical merger between two of five equally sized insurers is estimated to decrease hospital prices by 6.7%.

Using In-Hospital Mortality as an Indicator of Quality Care and Hospital Performance

Directory of Open Access Journals (Sweden)

Badia BISBIS

2016-06-01

Full Text Available The in-hospital mortality (MIH is used as a performance indicator and quality healthcare in hospital. However, the majority of deaths resulted from an inevitable disease process (severity of cases and / or co-morbidity, and not medical errors or changes in the quality of care. This work aims to make a distribution of deaths in the Regional Hospital of Eastern, Al Farabi hospital and to highlight that more studies on the MIH are required consistently with detailed clinical data at the admission. The MIH showed its limitation as a health care  indicator. The overall rate of in-hospital deaths within the Al Farabi hospital has averaged 2.4%, with 8.4% in the emergency unit, 28% in intensive care unit, 22% Neonatology unit, 1.6% in pediatric unit. The MIH may depend, firstly, on the condition of patients before hospitalization and secondly, on the conditions of their transfer from one institution to another that supports them as a last resort. Al Farabi hospital supports patients transferred from the provinces of the eastern region. Thus, 6% of patients who died in 2014 come from Berkane, 2% from  Nador, 2% from Bouarfa, 4% from  Taourirt and 2% from Jerrada. One might question about  the procedures and the conditions of such transfers. In conclusion, the overall MIH measured from routine data do not allow proper comparison between hospitals or the assessment of the quality of care and patient safety in the hospital. To do so, we should ideally have detailed clinical data on admission (e.g. type of admission, age of patient, sex, comorbidity, .... The MIH is however an important indicator to consider as a tool to detect potential  problems related to admission procedures and to suspect an area of "non-quality" in healthcare . The MIH is interesting for the patient and for the hospital because it serves the improvement of quality healthcare.

Structure and ionic conductivity of block copolymer electrolytes over a wide salt concentration range

Chintapalli, Mahati; Le, Thao; Venkatesan, Naveen; Thelen, Jacob; Rojas, Adriana; Balsara, Nitash

Block copolymer electrolytes are promising materials for safe, long-lasting lithium batteries because of their favorable mechanical and ion transport properties. The morphology, phase behavior, and ionic conductivity of a block copolymer electrolyte, SEO mixed with LiTFSI was studied over a wide, previously unexplored salt concentration range using small angle X-ray scattering, differential scanning calorimetry and ac impedance spectroscopy, respectively. SEO exhibits a maximum in ionic conductivity at twice the salt concentration that PEO, the homopolymer analog of the ion-containing block, does. This finding is contrary to prior studies that examined a more limited range of salt concentrations. In SEO, the phase behavior of the PEO block and LiTFSI closely resembles the phase behavior of homopolymer PEO and LiTFSI. The grain size of the block copolymer morphology was found to decrease with increasing salt concentration, and the ionic conductivity of SEO correlates with decreasing grain size. Structural effects impact the ionic conductivity-salt concentration relationship in block copolymer electrolytes. SEO: polystyrene-block-poly(ethylene oxide); also PS-PEO LiTFSI: lithium bis(trifluoromethanesulfonyl imide

Triorganotin Derivatives Induce Cell Death Effects on L1210 Leukemia Cells at Submicromolar Concentrations Independently of P-glycoprotein Expression

Directory of Open Access Journals (Sweden)

Viera Bohacova

2018-05-01

Full Text Available The acceleration of drug efflux activity realized by plasma membrane transporters in neoplastic cells, particularly by P-glycoprotein (P-gp, ABCB1 member of the ABC transporter family, represents a frequently observed molecular cause of multidrug resistance (MDR. This multiple resistance represents a real obstacle in the effective chemotherapy of neoplastic diseases. Therefore, identifying cytotoxic substances that are also effective in P-gp overexpressing cells may be useful for the rational design of substances for the treatment of malignancies with developed MDR. Here, we showed that triorganotin derivatives—tributyltin-chloride (TBT-Cl, tributyltin-bromide (TBT-Br, tributyltin-iodide (TBT-I and tributyltin-isothiocyanate (TBT-NCS or triphenyltin-chloride (TPT-Cl and triphenyltin-isothiocyanate (TPT-NCS—could induce the death of L1210 mice leukemia cells at a submicromolar concentration independently of P-gp overexpression. The median lethal concentration obtained for triorganotin derivatives did not exceed 0.5 µM in the induction of cell death of either P-gp negative or P-gp positive L1210 cells. Apoptosis related to regulatory pathway of Bcl-2 family proteins seems to be the predominant mode of cell death in either P-gp negative or P-gp positive L1210 cells. TBT-Cl and TBT-Br were more efficient with L1210 cells overexpressing P-gp than with their counterpart P-gp negative cells. In contrast, TBT-I and TPT-NCS induced a more pronounced cell death effect on P-gp negative cells than on P-gp positive cells. Triorganotin derivatives did not affect P-gp efflux in native cells measured by calcein retention within the cells. Taken together, we assumed that triorganotin derivatives represent substances suitable for suppressing the viability of P-gp positive malignant cells.

2010-01-01

Independent predictors of death and death or myocardial infarction (MI) during initial hospitalization of patients with acute coronary syndromes (ACS) were determined using database of Russian independent ACS registry RECORD. These predictors (admission Killip class II, ST-segment elevation 1 mm, systolic blood pressure 100 mm Hg, hemoglobin <110 g/L, age 65 years, history of diabetes) were attributed equal weight (1 point) and combined in a prognostic scale for assessment of risk of inhospital death and death or MI. The scale did not include markers of necrosis, and the most time consuming component was measurement of hemoglobin. Sensitivity and specificity of risk scores for prediction of death were 78.5%. The use of GRACE score in this group of patients gave similar results. These preliminary data require confirmation on larger populations of patients with ACS.

Studies have shown that malnutrition increases the risk of morbidity, mortality, the length of hospital stay, and costs in the elderly population. Approximately one third of all patients admitted to geriatric wards in Denmark are malnourished according to the Danish Geriatric database. The aim of this study is to describe and examine the sudden increase in deaths due to malnutrition in the elderly population in Denmark from 1999 and, similarly, the sudden decline in malnutrition related deaths in 2007. A descriptive epidemiologic study was performed. All Danes listed in the national death registry who died from malnutrition in the period from 1994 to 2012 are included. The number of deaths from malnutrition increased significantly during the period from 1999 to 2007, especially in the age group 70 years and over. Additionally, we document a surprising similarity between the development in excess mortality from malnutrition in the five Danish regions during the same period. During the period 1999-2007 malnutrition was the direct cause of 340 extra deaths, and probably ten times more registered under other diseases. This development in excess mortality runs parallel in all five Danish regions over time. Copyright © 2016 European Society for Clinical Nutrition and Metabolism. Published by Elsevier Ltd.

Lactation and breast milk can hold great value and meaning for grieving mothers who have experienced a recent death of an infant. Donation to a human milk bank (HMB) as an alternative to discarding breast milk is one means of respecting the value of breast milk. There is little research, national policy discussion, or organizational representation in Australia on the subject of breast milk donation after infant death. On 29 November 2013 the Mercy Hospital for Women in Melbourne, Australia hosted Australia's first National Stakeholder Meeting (NSM) on the topic of milk donation after neonatal death. The NSM drew together representatives from Australian HMBs, neonatal intensive care units (NICUs) currently using donor human milk, and Australia's chief NICU parent support organization. The NSM was video-recorded and transcribed, and analyzed thematically by researchers. This article reports the seven dominant themes discussed by stakeholders during the NSM: the spectrum of women's lactation and donation experiences after infant death; the roles of the HMB and NICU in meeting the needs of the bereaved donor; how bereaved mothers' lactation autonomy may interface with a HMB's donation guidelines; how milk donation may be discussed with bereaved mothers; the variation between four categories of milk donation after neonatal death; the impact of limited resources and few HMBs on providing donation programs for bereaved mothers in Australia. This article provides evidence from researchers and practitioners that can assist HMB staff in refining their bank's policy on milk donation after infant death, and provides national policy makers with key considerations to support lactation, human milk banking, and bereavement services nation-wide.

2012-03-01

Full Text Available Abstract Introduction There is a relative lack of information about the death rate and morbidity of non-cystic fibrosis bronchiectasis and most studies are limited due to referral bias. We wanted to assess death rate and morbidity in those patients at our hospital. Methods Adult patients seen at our department between June 2006 and November 2009 were recruited if the key string "bronchiect-" was mentioned in electronic clinical records and if chest CT imaging was available. Clinical records of all patients with confirmed radiologic diagnosis of bronchiectasis were reviewed and clinical characteristics were analyzed. Results 539 patients with a radiographic diagnosis of non-cystic fibrosis bronchiectasis were identified in a retrospective cross-sectional analysis giving a prevalence of 2.6% in our hospital population. A wide range of etiologies was found with idiopathic bronchiectasis in 26%. In the 41 months interval, 57 patients (10.6% died. We found a median exacerbation rate of 1.94 per year. Bacterial colonization status was associated with more deaths, exacerbation rate, symptoms and reduced pulmonary function. Pulmonary hypertension was found in 48% of our patients. Conclusions We evaluated a large non-cystic fibrosis bronchiectasis population, and provided new epidemiological data on associations between clinical characteristics and deaths and morbidity in these patients.

The objectives of this study were to assess the socio-demographic profile and to identify the risk factors of ante-partum fetal death which occurs after the age of viability of fetus. This prospective observational study was conducted in the Obstetrics and Gynaecology department of Ad-din Women Medical College Hospital from June 2009 to July 2010. A total of 14,015 pregnant patients were admitted in the study place after the age of viability, which was taken as 28 weeks of gestation for our facilities. Eighty-three (0.59%) of them were identified as intrauterine fetal death. Assessment of maternal socio-demographic characteristics and maternal-fetal risk factors were evaluated with a semi structured questionnaire which was pre-tested before executing in this study. Majority (81.92%, n=68) of the patients were below 30 years of age, 78.31% belonged to middle socioeconomic group. Almost 58% women had education below secondary school certificate (SSC) level and 28.91% took regular antenatal checkup. About 61.45% patients were multi-gravida. Most (59.04%) ante-partum deaths were identified below 32 weeks of pregnancy. Out of 83 patients, maternal risk factors were identified in 41(49.59%) cases where fetal risk factors were found in 16(19.27%) cases; no risk factors could be determined in rests. Hypertension (48.78%), diabetes (21.95%), hyperpyrexia (17.3%), abruptio placentae (4.88%) and UTI (7.36%) were identified as maternal factors; and congenital anomaly (37.5%), Rh incompatibility (37.5%), multiple pregnancy (12.5%) and post-maturity (12.5%) were the fetal risk factors. Here, proximal biological risk factors are most important in ante-partum fetal deaths. More investigations and facilities are needed to explain the causes of ante-partum deaths.

Objective Analyze trends in hospital cost and revenue, as well as price and quantity (1994–2005) as a function of health maintenance organization (HMO) penetration, HMO concentration, and for-profit (FP) HMO market share. Data Medicare hospital cost reports, AHA Annual Surveys, HMO data from Interstudy, and other supplemental data. Study Design A retrospective study of all short-term, general, nonfederal hospitals in metropolitan statistical areas (MSAs) in the United States from 1994 to 2005, using hospital/MSA fixed-effects translog regression models. Principal Findings A 10 percentage point increase in HMO enrollment is associated with 4.1–4.2 percent reduction in costs and revenues in the pre-2000 period but only a 2.1–2.5 percent reduction in the post-2000 period. Hospital revenue in HMO-dominant markets (highly concentrated HMO market and competitive hospital market) is 19–27 percent lower than other types of markets, and the difference is most likely due mainly to lower prices and to a lesser extent lower utilization. Conclusions The historical difference of lower spending in high HMO penetration markets compared with low HMO markets narrowed after 2000 and the relative concentration between HMO and hospital markets can substantially influence hospital spending. Additional research is needed to understand how different aspects of these two markets have changed and interacted and how they are causally linked to spending trends. PMID:19840134

Patients with a terminal illness should have access to their chosen location of death. Cancer is the leading cause of non-accidental death among adolescents and young adults (AYAs; those aged 15-39 years). Although surveys have suggested that a majority of these patients prefer a home death, to the authors' knowledge, little is known regarding their barriers to accessing their preferred location of death. As a first step, the authors sought to determine, across a large population, 20-year trends in the location of death among AYA patients with cancer. Using the Vital Statistics Death Certificate Database of the California Office of Statewide Health Planning and Development, the authors performed a retrospective, population-based analysis of California patients with cancer aged 15 to 39 years who died between 1989 and 2011. Sociodemographic and clinical factors associated with hospital death were examined using multivariable logistic regression. Of 30,573 AYA oncology decedents, 57% died in a hospital, 33% died at home, and 10% died in other locations (eg, hospice facility or nursing facility). Between 1989 and 1994, hospital death rates decreased from 68.3% to 53.6% and at-home death rates increased from 16.8% to 35.5%. Between 1995 and 2011, these rates were stable. Those individuals who were more likely to die in a hospital were those aged deaths occurred in a hospital, with a 5-year shift to more in-home deaths that abated after 1995. In-hospital deaths were more common among younger patients, patients of minority race/ethnicities, and those with a leukemia or lymphoma diagnosis. Further study is needed to determine whether these rates and disparities are consistent with patient preferences.

Quality anesthetic care is lacking in low- and middle-income countries (LMICs). Global health leaders call for perioperative capacity reports in limited-resource settings to guide improved health care initiatives. We describe a teaching hospital's resources and the national workforce and education in this LMIC capacity report. A prospective observational study was conducted at Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana, during 4 weeks in August 2016. Teaching hospital data were generated from observations of hospital facilities and patient care, review of archival records, and interviews with KATH personnel. National data were obtained from interviews with KATH personnel, correspondence with Ghana's anesthesia society, and review of public records. The practice of anesthesia at KATH incorporated preanesthesia clinics, intraoperative management, and critical care. However, there were not enough physicians to consistently supervise care, especially in postanesthesia care units (PACUs) and the critical care unit (CCU). Clean water and electricity were usually reliable in all 16 operating rooms (ORs) and throughout the hospital. Equipment and drugs were inventoried in detail. While much basic infrastructure, equipment, and medications were present in ORs, patient safety was hindered by hospital-wide oxygen supply failures and shortage of vital signs monitors and working ventilators in PACUs and the CCU. In 2015, there were 10,319 anesthetics administered, with obstetric and gynecologic, general, and orthopedic procedures comprising 62% of surgeries. From 2011 to 2015, all-cause perioperative mortality rate in ORs and PACUs was 0.65% or 1 death per 154 anesthetics, with 99% of deaths occurring in PACUs. Workforce and education data at KATH revealed 10 anesthesia attending physicians, 61 nurse anesthetists (NAs), and 7 anesthesia resident physicians in training. At the national level, 70 anesthesia attending physicians and 565 NAs cared for Ghana's population

There are three categories of deceased donors of kidney transplantation in China, donation after brain death (DBD), donation after circulatory death (DCD), and donation after brain death followed by circulatory death (DBCD) donors. The aim of this study was to compare the outcomes of kidney transplantation from these three categories of deceased donors. We retrospectively reviewed 469 recipients who received deceased kidney transplantation in our hospital from February 2007 to June 2015. The recipients were divided into three groups according to the source of their donor kidneys: DBD, DCD, or DBCD. The primary endpoints were delayed graft function (DGF), graft loss, and patient death. The warm ischemia time was much longer in DCD group compared to DBCD group (18.4 minutes vs 12.9 minutes, P < .001). DGF rate was higher in DCD group than in DBD and DBCD groups (22.5% vs 10.2% and 13.8%, respectively, P = .021). Urinary leakage was much higher in DCD group (P = .049). Kaplan-Meier analysis showed that 1-, 2-, and 3-year patient survivals were all comparable among the three groups. DBCD kidney transplantation has lower incidences of DGF and urinary leakage than DCD kidney transplant. However, the overall patient and graft survival were comparable among DBD, DCD, and DBCD kidney transplantation. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available OBJECTIVE: To describe the case-fatality rate (CFR and risk factors of death in children with community-acquired acute pneumonia (CAP in a pediatric university hospital. METHOD: A longitudinal study was developed with prospective data collected from 1996 to 2011. Patients aged 1 month to 12 years were included in the study. Those who left the hospital against medical orders and those transferred to ICU or other units were excluded. Demographic andclinical-etiological characteristics and the initial treatment were studied. Variables associated to death were determined by bivariate and multivariate analysis using logistic regression. RESULTS: A total of 871 patients were selected, of whom 11 were excluded; thus 860 children were included in the study. There were 26 deaths, with a CFR of 3%; in 58.7% of these, penicillin G was the initial treatment. Pneumococcus was the most common pathogen (50.4%. From 1996 to 2000, there were 24 deaths (93%, with a CFR of 5.8% (24/413. From 2001 to 2011, the age group of hospitalized patients was older (p = 0.03, and the number of deaths (p = 0.02 and the percentage of disease severity were lower (p = 0.06. Only disease severity remained associated to death in the multivariate analysis (OR = 3.2; 95%CI: 1.2-8.9; p = 0.02. CONCLUSION: When the 1996-2000 and 2001-2011 periods were compared, a significant reduction in CFR was observed in the latter, as well as a change in the clinical profile of the pediatric in patients at the institute. These findings may be related to the improvement in the socio-economical status of the population. Penicillin use did not influence CFR.

Full Text Available Abstract Background Increasing our understanding of the factors affecting the severity of the 2009 A/H1N1 influenza pandemic in different regions of the world could lead to improved clinical practice and mitigation strategies for future influenza pandemics. Even though a number of studies have shed light into the risk factors associated with severe outcomes of 2009 A/H1N1 influenza infections in different populations (e.g., [1-5], analyses of the determinants of mortality risk spanning multiple pandemic waves and geographic regions are scarce. Between-country differences in the mortality burden of the 2009 pandemic could be linked to differences in influenza case management, underlying population health, or intrinsic differences in disease transmission [6]. Additional studies elucidating the determinants of disease severity globally are warranted to guide prevention efforts in future influenza pandemics. In Mexico, the 2009 A/H1N1 influenza pandemic was characterized by a three-wave pattern occurring in the spring, summer, and fall of 2009 with substantial geographical heterogeneity [7]. A recent study suggests that Mexico experienced high excess mortality burden during the 2009 A/H1N1 influenza pandemic relative to other countries [6]. However, an assessment of potential factors that contributed to the relatively high pandemic death toll in Mexico are lacking. Here, we fill this gap by analyzing a large series of laboratory-confirmed A/H1N1 influenza cases, hospitalizations, and deaths monitored by the Mexican Social Security medical system during April 1 through December 31, 2009 in Mexico. In particular, we quantify the association between disease severity, hospital admission delays, and neuraminidase inhibitor use by demographic characteristics, pandemic wave, and geographic regions of Mexico. Methods We analyzed a large series of laboratory-confirmed pandemic A/H1N1 influenza cases from a prospective surveillance system maintained by the

Clinical Profiles and Factors Associated with Death in Adults with Dengue Admitted to Intensive Care Units, Minas Gerais, Brazil.

Full Text Available The purpose of our study was to describe the clinical profile of dengue-infected patients admitted to Brazilian intensive care units (ICU and evaluate factors associated with death. A longitudinal, multicenter case series study was conducted with laboratory-confirmed dengue patients admitted to nine Brazilian ICUs situated in Minas Gerais state, southeastern Brazil from January 1, 2008, to December 31, 2013. Demographic, clinical and laboratory data; disease severity scores; and mortality were evaluated. A total of 97 patients were studied. The in-ICU and in-hospital mortality rates were 18.6% and 19.6%, respectively. Patients classified as having severe dengue according to current World Health Organization classifications showed an increased risk of death in a univariate analysis. Nonsurvivors were older, exhibited lower serum albumin concentrations and higher total leukocyte counts and serum creatinine levels. Other risk factors (vomiting, lethargy/restlessness, dyspnea/respiratory distress were also associated with death in a univariate analysis. Multivariate analysis indicated that in-hospital mortality was significantly associated with Acute Physiology and Chronic Health Evaluation II and the Sequential Organ Failure Assessment score. The ICU and in-hospital mortality observed in this study were higher than values reported in similar studies. An increased frequency of ICU admission due to severe organ dysfunction, higher severity indices and scarcity of ICU beds may partially explain the higher mortality.

The death notification process can affect family grief and bereavement. It can also affect the well-being of involved physicians. There is no standardized process for making death notification phone calls. We assumed that residents are likely to be unprepared before and troubled after. We investigated current death notification practices to develop an evidence-based template for standardizing this process. We used results of a literature review and open-ended interviews with faculty, residents, and widows to develop a survey regarding resident training and experience in death notification by phone. We invited all internal medicine (IM) residents at our institution to complete the survey. Sixty-seven of 93 IM residents (72%) responded to the survey. Eighty-seven percent of responders reported involvement in a death that required notification by phone. Eighty percent of residents felt inadequately trained for this task. Over 25% reported that calls went poorly. Attendings were involved in 17% of cases. Primary care physicians were not involved. Nurses and chaplains were not involved. Respondents never delayed notification of death until family arrived at the hospital. There was no consistent approach to rehearsing or making the call, advising families about safe travel to the hospital, greeting families upon arrival, or following up with expressions of condolence. Poor communication skills during death notification may contribute to complicated grief for surviving relatives and stress among physicians. This study is the first to describe current practices of death notification by IM residents. More training is needed and could be combined with training in disclosure of medical error.

Heart failure (HF) patients have a higher risk of recurrent HF and cardiac death, and electrical remodeling is considered to be an important factor for HF progression. The present study aimed to validate the utility of electrocardiogram and Holter monitoring for the risk stratification of HF patients. Our study comprised 215 patients (144 males, mean age 62 years) who had been hospitalized due to acute decompensated HF. Electrocardiogram (QRS duration and QTc interval) and 24-hour Holter monitoring (heart rate variability, heart rate turbulence and T-wave alternans [TWA]) were performed in stable condition before discharge. The clinical characteristics and outcomes were then investigated. During a median follow-up period of 2.7 years, there were 83 (38.6%) cardiac events (re-hospitalization due to worsening HF [n = 51] or cardiac death [n = 32]). The patients with cardiac events had a lower turbulence slope (TS) and higher TWA compared to those without cardiac events (TS, 3.0±5.5 ms/RR vs. 5.3±5.6 ms/RR, P = 0.001; TWA, 66.1±19.6 μV vs. 54.7±15.1 μV, P < 0.001). Univariable analysis showed that TS, TWA, QRS duration, and QTc interval were associated with cardiac events (P = 0.004, P < 0.001, P = 0.037 and P = 0.024, respectively), while the multivariable analysis after the adjustment of multiple confounders showed that TS and TWA were independent predictive factors of cardiac events with a hazard ratio of 0.936 and 1.015 (95% confidence interval [CI]: 0.860-0.974, P = 0.006; and 95% CI: 1.003-1.027, p = 0.016), respectively. The measurement of TS and TWA is useful for assessing risk for re-hospitalization and cardiac death in HF patients. This article is protected by copyright. All rights reserved.

Objective A better understanding of risk factors for pneumonia-caused death may help to improve the clinical management of dementia. Methods A retrospective observational study was conducted by reviewing the medical charts and autopsy reports of 204 patients who were admitted to hospital, underwent a post-mortem examination, and who were neuropathologically diagnosed with dementia. The risk factors for pneumonia-caused death were examined both as underlying and immediate causes of death using logistic regression models. Results A high frequency of pneumonia-caused death was observed both in underlying- (37.3%) and immediate- (44.1%) cause of death, but varied according to the subtypes of dementia. The factors related to pneumonia-caused death (underlying) were subtypes of dementia; Alzheimer's disease (odds ratio [OR], 2.891; 95% confidence interval [CI], 1.459-5.730); argyrophilic grain disease (OR, 3.148; 95% CI, 0.937-10.577); and progressive supranuclear palsy (OR, 34.921; 95% CI, 3.826-318.775), dysphagia (OR, 2.045; 95% CI, 1.047-3.994), diabetes mellitus (OR, 3.084; 95% CI, 1.180-8.061) and conversely related with heart failure (OR, 0.149; 95% CI, 0.026-0.861). Factors relating to pneumonia-caused death (immediate) were incidence of pneumonia during hospitalizations (OR, 32.579; 95%CI, 4.308-246.370), gender-male (OR, 2.060; 95% CI, 1.098-3.864), and conversely related with malignant neoplasm (OR, 0.220; 95% CI, 0.058-0.840). Conclusion The different factors relating to the pneumonia-caused death were evaluated depending on whether pneumonia was the underlying- or immediate-cause of death. Strengthening clinical management on dysphagia and diabetes mellitus, and preventing incidence of pneumonia during hospitalization appear to be the important for the terminal stage of hospitalized patients with dementia.

Questioning dehumanization: intersubjective dimensions of violence in the Nazi concentration and death camps.

Science.gov (United States)

Lang, Johannes

2010-01-01

Using the violence in Nazi concentration and death camps as its case study, this article explores the theoretical and empirical limits of the concept of dehumanization-the process by which the perpetrators come to perceive their victims as "not human" or "subhuman"-and delineates appropriate alternatives to the concept. The author argues that excessive violence is commonly misunderstood and misrepresented as dehumanization because it seems to aim at effacing the victim's human appearance. Yet, it is more accurate to see such violence as a ploy to extend the perpetrator's sense of power over another human being; it is precisely the human quality of the interaction that provides the violence with much of its meaning. The argument has a moral edge, demonstrating that the concept ultimately reduces, or displaces, the true horror of the killer-victim interaction.

Pablo RODRÍGUEZ HERRERO

2015-03-01

Full Text Available Despite being an essential human condition, death is an under-researched area in the effort to improve people with intellectual disabilities’ life quality. In this article we describe the concept of death among young people with intellectual disabilities. A mixed research methodology that includes quantitative and qualitative approaches was employed, including both a questionnaire and a semi-structured interview. Results indicate that participants have difficulty understanding of biological dimensions of death. Moreover, it has been found that participants present a wide range of opinions, attitudes and beliefs about death. Conclusions reflect on implications of these results for a possible pedagogy on death in young adults that would include accompaniment during bereavement.

Hospitalized patients with comorbid diabetes mellitus may have worse outcomes than the others. We conducted a study to assess whether comorbid diabetes affects in-hospital mortality and length of stay. For this population-based study, we analyzed the administrative databases of the Regional Health Information System of the Region Friuli Venezia Giulia, where the Hospital of Udine is located. Hospital discharge data were linked at the individual patient level with the regional Diabetes Mellitus Registry to identify diabetic patients. For each 3-digit ICD-9-CM discharge diagnosis code, we assessed the difference in length of stay and in-hospital mortality between diabetic and non-diabetic patients. We conducted both univariate and multivariate analyses, adjusted for age, sex, Charlson's comorbidity score, and urgency of hospitalization, through linear and logistic regression models. After adjusting for potential confounders, diabetes significantly increased the risk of in-hospital death among patients hospitalized for bacterial pneumonia (OR = 1.94) and intestinal obstruction (OR = 4.23) and length of stay among those admitted for several diagnoses, including acute myocardial infarction and acute renal failure. Admission glucose blood level was associated with in-hospital death in patients with pneumonia and intestinal obstruction, and increased length of stay for several conditions. Patients with diabetes mellitus who are hospitalized for other health problems may have increased risk of in-hospital death and longer hospital stay. For this reason, diabetes should be promptly recognized upon admission and properly managed.

A circular organization chart promotes a hospital-wide focus on teams.

Our Lady of the Way Hospital, like most hospitals in the late 1980s and early 1990s, exemplified the bureaucratic organization represented by the traditional "line and box organization chart." Additionally, as in most small hospitals, the CEO of Our Lady of the Way Hospital--a 39-bed, JCAHO accredited, general, acute care hospital in Martin, Kentucky--had direct management responsibility for several functional departments. In 1992, administration replaced the traditional, hierarchical organization chart with a circular structure that reflected its increased reliance on team processes throughout the organization. The new structure also significantly reduced the number of reporting assignments to the CEO. This article describes the hospital's transition to a team-based organization, illustrates the application of a circular organization chart, and assesses its value and limitations.

To determine the quality and effectiveness of national data linkage capacity by performing a proof-of-concept project investigating cross-border hospital use and hospital-related deaths. Analysis of person-level linked hospital separation and death registration data of all public and private hospital patients in New South Wales, Queensland and Western Australia and of public hospital patients in South Australia, totalling 7.7 million hospital patients from 1 July 2004 to 30 June 2009. Counts and proportions of hospital stays and patient movement patterns. 223 262 patients (3.0%) travelled across a state border to attend hospitals, in particular, far northern and western NSW patients travelling to Queensland and SA hospitals, respectively. A further 48 575 patients (0.6%) moved their place of residence interstate between hospital visits, particularly to and from areas associated with major mining and tourism industries. Over 11 000 cross-border hospital transfers were also identified. Of patients who travelled across a state border to hospital, 2800 (1.3%) died in that hospital. An additional 496 deaths recorded in one jurisdiction occurred within 30 days of hospital separation from another jurisdiction. Access to person-level data linked across jurisdictions identified geographical hot spots of cross-border hospital use and hospital-related deaths in Australia. This has implications for planning of health service delivery and for longitudinal follow-up studies, particularly those involving mobile populations.

Identification of patients with non-ST elevation acute myocardial infarction (NSTEMI) at higher risk of in-hospital life-threatening ventricular arrhythmias (LT-VA) and death is crucial for determining appropriate levels of care/monitoring during hospitalisation. We assessed predictors of in-hospital LT-VA and all-cause mortality in a consecutive series of NSTEMI patients. We prospectively studied 1325 consecutive patients (69.7% males, median age 70 (61-79) years) presenting with NSTEMI and undergoing continuous electrocardiographic monitoring. The primary study end-point was the occurrence of spontaneous (unrelated to coronary interventions) in-hospital LT-VA, including sustained ventricular tachycardia and ventricular fibrillation; the secondary end-point was in-hospital mortality from all causes. Of 1325 patients, 21 (1.5%) experienced LT-VA and 62 (4.7%) died from either arrhythmias (n=1) or other causes (n=61). Seven of the 20 patients who survived LT-VA subsequently died of heart failure. Independent predictors of in-hospital LT-VA were the Global Registry of Acute Coronary Events (GRACE) score >140 (odds ratio (OR)=7.5; 95% confidence interval (CI) 1.7-33.3; p=0.008) and left ventricular ejection fraction (LV-EF)140 (OR=14.6; 95% CI 3.4-62) and LV-EF 140 and LV-EF<35%, while it was respectively 0.2% and 0% among the 627 (47.3%) with GRACE score ≤140 and LV-EF ≥35%. Simple risk stratification at admission based on GRACE score and echocardiographic LV-EF allows early identification of NSTEMI patients at higher risk of both in-hospital LT-VA and all-cause mortality. © The European Society of Cardiology 2014.

Despite epidemiologic, experimental and observational data on the association of environmental tobacco smoke (ETS) and adverse health effects, bar and restaurant workers remain exposed to ETS in the majority of states and countries. Three public health surveillance systems were used to identify and conduct a follow-up investigation of a reported acute asthma death of a young waitress in a bar. The waitress collapsed at the bar where she worked and was declared dead shortly thereafter. Evaluation of the circumstances of her death and her medical history concluded that her death was from acute asthma due to environmental tobacco smoke at work. This is the first reported acute asthma death associated with work-related ETS. Recent studies of asthma among bar and restaurant workers before and after smoking bans support this association. This death dramatizes the need to enact legal protections for workers in the hospitality industry from secondhand smoke.

This study analyzed big data for serum thyrotropin (TSH), free triiodothyronine (fT3), and free thyroxine (fT4) concentrations in patients who had attended the outpatient clinic of Ito Hospital (Tokyo, Japan) during a recent six-year period (between January 1, 2010, and December 31, 2015) in order to investigate for seasonal changes. The serum TSH concentrations were reviewed for all 135,417 patients aged >20 years. Patients with any thyroid diseases were included, irrespective of whether they were receiving drug therapy. In total 1,637,721 serum samples were analyzed for TSH, 1,626,269 for fT3, and 1,669,381 for fT4. It was observed that the TSH concentrations showed annual changes during the six-year period. They decreased during the summer, while they increased during the winter. The TSH concentrations were negatively correlated with the daily temperatures (Spearman rank correlation coefficient -0.4486; p < 0.0001). The same applied for the correlation between fT3 concentrations and daily temperatures. The fact that the TSH concentrations show annual changes in areas where the temperature ranges during the year are rather wide should be borne in mind for interpretation of results.

The occurred death of a convict in prison, police custody cell or in a hospital always attracts public attention and can be considered as a complex phenomenon. The aim of this study is to evaluate the data obtained from autopsies performed to the custody and prison deaths in Istanbul and to discuss the possible solutions by comparing with the literature. It is also aimed to discuss the postponement of the sentence and presidential amnesty facts in Turkey. Deaths of inmates, which occurred in hospitals, prisons, prison medical rooms, police vans and police custody cells between 2010 and 2012 in Istanbul, Turkey were included in the study. Totally 125 cases were found and 98.4% of them were male. Natural deaths accounted for a great majority of deaths (83.2%). The most common natural cause was cardiovascular diseases. Unnatural deaths accounted for 15.2% of the deaths. Death reason cannot be determined for 1.6% of the cases. More than half of the cases (56%) were died at the hospital, 34.4% were died at the prison, 4% of them at the police van, 3.2% were died under police custody and 2.4% were died at the prison medical room. Moreover, twelve of these cases had applied to Third Specialization Board previously for postponement of the sentence or Presidential amnesty. Totally five of these cases found suitable for postponement of the sentence. Prison conditions should be improved, prisoners with chronic diseases should be examined periodically and if appropriate their sentences should be postponed until they heal.

Preventable trauma deaths: from panel review to population based-studies

Directory of Open Access Journals (Sweden)

Vesconi Sergio

2006-04-01

Full Text Available Abstract Preventable trauma deaths are defined as deaths which could be avoided if optimal care has been delivered. Studies on preventable trauma deaths have been accomplished initially with panel reviews of pre-hospital and hospital charts. However, several investigators questioned the reliability and validity of this method because of low reproducibility of implicit judgments when they are made by different experts. Nevertheless, number of studies were published all around the world and ultimately gained some credibility, particularly in regions where comparisons were made before and after trauma system implementation with a resultant fall in mortality. During the last decade of century the method of comparing observed survival with probability of survival calculated from large trauma registries has obtained popularity. Preventable trauma deaths were identified as deaths occurred notwithstanding a high calculated probability of survival. In recent years, preventable trauma deaths studies have been replaced by population-based studies, which use databases representative of overall population, therefore with high epidemiologic value. These databases contain readily available information which carry out the advantage of objectivity and large numbers. Nowadays, population-based researches provide the strongest evidence regarding the effectiveness of trauma systems and trauma centers on patient outcomes.

The European General Practitioners Research Network (EGPRN) designed and validated a comprehensive definition of multimorbidity using a systematic literature review and qualitative research throughout Europe. This definition was tested as a model to assess death or acute hospitalization in multimorbid outpatients. To assess which criteria in the EGPRN concept of multimorbidity could detect outpatients at risk of death or acute hospitalization in a primary care cohort at a 6-month follow-up and to assess whether a large scale cohort with FPs would be feasible. Family Physicians included a random sample of multimorbid patients who attended appointments in their offices from July to December 2014. Inclusion criteria were those of the EGPRN definition of Multimorbidity. Exclusion criteria were patients under legal protection and those unable to complete the 2-year follow-up. Statistical analysis was undertaken with uni- and multivariate analysis at a 6-month follow-up using a combination of approaches including both automatic classification and expert decision making. A Multiple Correspondence Analysis (MCA) completed the process with a projection of illustrative variables. A logistic regression was finally performed in order to identify and quantify risk factors for decompensation. 19 FPs participated in the study. 96 patients were analyzed. 3 different clusters were identified. MCA showed the central function of psychosocial factors and peaceful versus conflictual relationships with relatives in all clusters. While taking into account the limit of a small cohort, age, frequency of family physician visits and extent of family difficulties were the factors which predicted death or acute hospitalization. A large scale cohort seems feasible in primary care. A sense of alarm should be triggered to prevent death or acute hospitalization in multimorbid older outpatients who have frequent family physician visits and who experience family difficulties.

2016-12-01

Full Text Available Background: The purpose of this study is to evaluate the concentration of cardiovascular surgical procedures in a metropolitan area and investigate the perception of specialists regarding governmental policies to resolve this imbalance. Methods: From March to May 2015, surveys were distributed to members of the Thoracic and Cardiovascular Surgery Association. The final pool of research subjects consisted of 75 respondents. Subjects were queried regarding the concentration of cardiovascular operations in metropolitan areas, alternatives to the imbalance, and governmental policies to resolve the inequalities. Results: Survey participants responded that South Korea needs governmental policies to alleviate the concentration of cardiovascular surgery patients in large metropolitan hospitals. Participants agreed that the freedom to choose medical institutions and improved accessibility to metropolitan hospitals due to advanced transportation systems were some of the causes for the concentration. A majority (98.7% of respondents thought establishing thoracic and cardiovascular surgery centers in provinces was an appropriate solution to alleviate the concentration. Thoracic and cardiovascular surgery specialists were ranked as the number one group on which to focus development. Conclusion: Developing and carrying out policies to establish thoracic and cardiovascular surgery centers in provinces will alleviate the regional imbalance in available heart surgery services and an overall improvement in cardiovascular disease treatment in South Korea.

Full Text Available A Bayesian binary regression model is developed to predict death of patients after acute myocardial infarction (AMI. Markov Chain Monte Carlo (MCMC methods are used to make inference and to evaluate Bayesian binary regression models. A model building strategy based on Bayes factor is proposed and aspects of model validation are extensively discussed in the paper, including the posterior distribution for the c-index and the analysis of residuals. Risk assessment, based on variables easily available within minutes of the patients' arrival at the hospital, is very important to decide the course of the treatment. The identified model reveals itself strongly reliable and accurate, with a rate of correct classification of 88% and a concordance index of 83%.Um modelo bayesiano de regressão binária é desenvolvido para predizer óbito hospitalar em pacientes acometidos por infarto agudo do miocárdio.

To aid diagnostics, patient stratification and studies seeking to find treatments for the related diseases motor neuron disease (MND) and frontotemporal dementia (FTD), there is a need to establish a way to assess disease severity and the amount of ongoing neurodegeneration. Previous studies have suggested that cerebrospinal fluid (CSF) neurofilament light (NFL) may serve this purpose. We cross-referenced the Swedish mortality registry with the laboratory database at Sahlgrenska University Hospital to produce a dataset of CSF NFL concentrations and mortality information for 715 MND patients, 87 FTD patients, and 107 healthy controls. Biomarker concentrations were analysed in relation to recorded cause of death and time of death. MND patients had significantly higher CSF NFL concentrations than FTD patients. Both groups had significantly higher concentrations than the healthy controls (mean 709% increase in MND and 307% increase in FTD). Higher concentrations of CSF NFL were associated with shorter survival in both MND and FTD. The results of this study strengthen the notion of CSF NFL as a useful tool for determining disease intensity in MND and FTD patients. Further studies in patient cohorts with clinically subtyped and genetically classified diagnoses are needed.

The number and mass concentration, size distribution, and the concentration of 16 elements were studied in aerosol samples during the Spring Festival celebrations in 2013 in Beijing, China. Both the number and mass concentration increased sharply in a wide range from 10 nm to 10 μm during the firecrackers and fireworks activities. The prominent increase of the number concentration was in 50 nm-500 nm with a peak of 1.7 × 10(5)/cm(3) at 150 nm, which is 8 times higher than that after 1.5 h. The highest mass concentration was in 320-560 nm, which is 4 times higher than the control. K, Mg, Sr, Ba and Pb increased sharply during the firework activities in PM10. Although the aerosol emission from firework activities is a short-term air quality degradation event, there may be a substantial hazard arising from the chemical composition of the emitted particles.

Minimal invasive but accurate methods to establish the cause of death in HIV-infected patients are needed. We studied the agreement in cause of death between blind and ultrasound-guided needle autopsy and complete autopsy in HIV-infected patients in Uganda. We subsequently performed a blind and ultrasound-guided needle autopsy followed by a complete autopsy in HIV-infected adults who died during hospitalization. Two teams of pathologists reviewed the tissue from either the needle autopsies or the complete autopsy and formulated the major diagnoses, that is, diseases directly contributing to death. The primary outcome was concordance in major diagnosis between needle and complete autopsies. We performed 96 blind needle and complete autopsies and 95 ultrasound-guided needle autopsies. Concordance in major diagnosis between blind needle and complete autopsy was 50%. For the main major diagnosis, tuberculosis (TB) concordance was higher (71%; P autopsy identified at least 1 major diagnosis in 60% of patients; and in 46%, there was complete concordance for all major diagnoses. The main reason for discordance was sampling error of the lesion. Concordance with the addition of ultrasound guidance was 52% for all major diagnoses and 79% for TB. Major diagnoses were mainly identified in tissue cores from the liver (76%) and the spleen (82%). Blind needle autopsy identified half of the major diagnosis. The addition of ultrasound guidance did not significantly improve the performance of needle autopsy. Needle autopsy is a valuable method to confirm causes of death in HIV-infected patients, especially for highly prevalent diseases like TB.

Sudden cardiac death (SCD) has not been investigated separately in Greece. The aim of this study is to describe the epidemiological characteristics of people dying suddenly out of hospital in an area of Greece. In 1990, a population based study was started to detect the cases of people dying suddenly out of hospital (Greece (Ioannina area: 160,000 inhabitants). During a 3.5 year period, 283 potential cases aged 30-70 years were identified by monitoring the mortality in the emergency rooms of the two hospitals of the area, the coroner's office and the death certificates from the Government Department of Statistics. The diagnosis of SCD was established in 223 (183 men, 40 women; mean ages 59 and 61 years respectively) after visiting and interviewing the relatives and/or the family doctors within 12 days (range 1-28) after the death. SCD in the study accounts for 50% of all cardiovascular deaths and is the most common cause of death after neoplasia. The most common place of death was home (151 cases, 68%), and in 174 cases (78%) deaths occurred while the patients were relaxing or during routine activities. Prodromal symptoms were reported in 57 cases (26%). The time of day of death showed a circadian variation, with a peak in the late morning from 9:00 to 12:00. Ninety four (42%) had a prior history of heart disease. One hundred and ninety one cases (86%) occurred in the subgroup of age 50-70 years.(ABSTRACT TRUNCATED AT 250 WORDS)

The objective of this study was to compare in-hospital deaths and length of stays for diabetes-related preventable hospitalizations (D-RPHs) in Hawai'i for Asian American, Pacific Islander, and white Medicare recipients aged 65 years or older. We considered all hospitalizations of older (>65 years) Japanese, Chinese, Native Hawaiians, Filipinos, and whites living in Hawai'i with Medicare as the primary insurer from December 2006 through December 2010 (n = 127,079). We used International Classification of Diseases - 9th Revision (ICD-9) codes to identify D-RPHs as defined by the Agency for Healthcare Research and Quality. Length of stays and deaths during hospitalization were compared for Asian American and Pacific Islander versus whites in multivariable regression models, adjusting for age, sex, location of residence (Oahu, y/n), and comorbidity. Among the group studied, 1,700 hospitalizations of 1,424 patients were D-RPHs. Native Hawaiians were significantly more likely to die during a D-RPH (odds ratio [OR], 3.92; 95% confidence interval [CI], 1.42-10.87) than whites. Filipinos had a significantly shorter length of stay (relative risk [RR], 0.77; 95% CI, 0.62-0.95) for D-RPH than whites. Among Native Hawaiians with a D-RPH, 59% were in the youngest age group (65-75 y) whereas only 6.3% were in the oldest (≥85 y). By contrast, 23.2% of Japanese were in the youngest age group, and 32.2% were in the oldest. This statewide study found significant differences in the clinical characteristics and outcomes of D-RPHs for Asian American and Pacific Islanders in Hawai'i. Native Hawaiians were more likely to die during a D-RPH and were hospitalized at a younger age for a D-RPH than other studied racial/ethnic groups. Focused interventions targeting Native Hawaiians are needed to avoid these outcomes.

Full Text Available Background: Sudden death (SD remains an important worldwide public health problem. The incidence of SD and causes vary in different societies, and these differences are influenced also by demographic and clinical factors such as age, gender and prodromal symptoms and signs. This six-year study describes the influence of these factors on SD. Materials and Methods: This is a retrospective study of SD in all age groups undertaken in King Fahd Hospital of the University (KFHU, Eastern Saudi Arabia. All cases of death (1273 total, 1050 expected death and 223 cases of sudden unexpected death that occurred between January 1, 2000 and December 31, 2005 were investigated and subsequently analyzed on demographic and clinical parameters of the deceased patients. The statistical analysis was performed as appropriate to illustrate any possible association between different demographic variables and SD. Results: There were 223 cases of SD (17.5% out of 1273 total deaths in KFHU in the 6-year study period. There was a definite influence of age on the incidence of sudden death (SD as it increased clearly at the two ends of the age spectrum, 32.2% of the cases were infants (from birth to 12 months, and 31.4% were elderly (> 60 year-old. However, among infantile age group, the highest frequency of SD (22.2% of the cases was among the neonates. There was also a significant trend of gender influence on the incidence of SD which was higher in men than women (56% vs. 42%. The influence of prodromal symptoms and signs on SD was variable. Dyspnea and cough as major symptoms of cardiovascular and respiratory disease were the most frequent presenting symptoms in 32.3% of the cases, followed by fever as a sign of infections in 11.7%, premature infants in 10.8%, circulatory collapse in 9.4%, and angina in 7.6% of the cases. Conclusion: The current study indicated a definite influence of age, gender and prodromal symptoms on the incidence of SD. The highest incidence

What works in 'real life' to facilitate home deaths and fewer hospital admissions for those at end of life?: results from a realist evaluation of new palliative care services in two English counties.

WE EVALUATED END OF LIFE CARE SERVICES IN TWO ENGLISH COUNTIES INCLUDING: coordination centres, telephone advice line, 'Discharge in Reach' nurses, a specialist community personal care team and community nurse educators. Elsewhere, we published findings detailing high family carer satisfaction and fewer hospital admissions, Accident and Emergency attendances and hospital deaths for service users compared to controls. The aim of this paper is to discuss what contributed to those outcomes. Using realist evaluation, data collection included documentation (e.g. referral databases), 15 observations of services and interviews with 43 family carers and 105 professionals. Data were analysed using framework analysis, applying realist evaluation concepts. Findings were discussed at successive team meetings and further data was collected until team consensus was reached. Services 'worked' primarily for those with cancer with 'fast track' funding who were close to death. Factors contributing to success included services staffed with experienced palliative care professionals with dedicated (and sufficient) time for difficult conversations with family carers, patients and/or clinical colleagues about death and the practicalities of caring for the dying. Using their formal and informal knowledge of the local healthcare system, they accessed community resources to support homecare and delivered excellent services. This engendered confidence and reassurance for staff, family carers and patients, possibly contributing to less hospital admissions and A&E attendances and more home deaths. With demand for 24-hour end of life care growing and care provision fragmented across health and social care boundaries, services like these that cut across organisational sectors may become more important. They offer an overview to help navigate those desiring a home death through the system.

Clostridium difficile is the principal cause of infectious diarrhea in hospitalized patients. The aim of this study was to describe and compare length of stay (LOS), costs, and in-hospital deaths for C difficile infection (CDI) and non-CDI hospitalizations, in a cohort of middle-aged and older Australians. We used survey data from the 45 and Up Study, linked to hospitalization and death data. We calculated the average LOS and costs per hospitalization, and the proportion of in-hospital deaths for CDI and non-CDI hospitalizations. We then compared hospitalizations with CDI as a secondary diagnosis to non-CDI hospitalizations by stratifying hospitalizations based on principal diagnosis and then using generalized linear models to compare LOS and in-hospital costs, and logistic regression for in-hospital deaths, adjusting for age and sex. There were 641 CDI hospitalizations during 2006-2012. The average LOS was 17 days; the average cost per hospitalization was AUD 12,704; and in 7.3% of admissions (47 out of 641) the patient died. After adjusting for age and sex, hospitalizations with CDI were associated with longer LOS, higher costs, and a greater proportion of in-hospital deaths compared with hospitalizations with similar principal diagnosis but without CDI. CDI places additional burden on the Australian hospital system, with CDI patients having relatively lengthy hospital stays and high costs.

Magnetic resonance imaging (MRI) was undertaken for two patients who suffered from severe cerebrovascular diseases and were clinically brain dead. The MRI system we used was Resona (Yokogawa Medical Systems, superconductive system 0.5 T) and the CT apparatus was Toshiba TCT-300. Initial CT and MRI were undertaken as soon as possible after admission, and repeated sequentially. After diagnosis of brain death, we performed angiography to determine cerebral circulatory arrest, and MRI obtained at the same time was compared with the angiogram and CT. Case 1 was a 77-year-old man who was admitted in an unconscious state. CT and MRI on the second day after hospitalization revealed cerebellar infarction. He was diagnosed as brain dead on day 4. Case 2 was a 35-year-old man. When he was transferred to our hospital, he was in cardiorespiratory arrested. Cardiac resuscitation was successful but no spontaneous respiration appeared. CT and MRI on admission revealed right intracerebral hemorrhage. Angiography revealed cessation of contrast medium in intracranial vessels in both of the patients. We found no 'flow signal void sign' in the bilateral internal carotid and basilar arteries on MRI images in both cases after brain death. MRI, showing us the anatomical changes of the brain, clearly revealed brain herniations, even though only nuclear findings of 'brain tamponade' were seen on CT. But in Case 1, we could not see the infarct lesions in the cerebellum on MR images obtained after brain death. This phenomenon was caused by the whole brain ischemia masking the initial ischemic lesions. We concluded that MRI was useful not only the anatomical display of lesions and brain herniation with high contrast resolution but for obtaining information on cerebral circulation of brain death.

To evaluate the effect of implementing real-time audiovisual feedback with and without postevent debriefing on survival and quality of cardiopulmonary resuscitation quality at in-hospital cardiac arrest. A two-phase, multicentre prospective cohort study. Three UK hospitals, all part of one National Health Service Acute Trust. One thousand three hundred and ninety-five adult patients who sustained an in-hospital cardiac arrest at the study hospitals and were treated by hospital emergency teams between November 2009 and May 2013. During phase 1, quality of cardiopulmonary resuscitation and patient outcomes were measured with no intervention implemented. During phase 2, staff at hospital 1 received real-time audiovisual feedback, whereas staff at hospital 2 received real-time audiovisual feedback supplemented by postevent debriefing. No intervention was implemented at hospital 3 during phase 2. The primary outcome was return of spontaneous circulation. Secondary endpoints included other patient-focused outcomes, such as survival to hospital discharge, and process-focused outcomes, such as chest compression depth. Random-effect logistic and linear regression models, adjusted for baseline patient characteristics, were used to analyze the effect of the interventions on study outcomes. In comparison with no intervention, neither real-time audiovisual feedback (adjusted odds ratio, 0.62; 95% CI, 0.31-1.22; p=0.17) nor real-time audiovisual feedback supplemented by postevent debriefing (adjusted odds ratio, 0.65; 95% CI, 0.35-1.21; p=0.17) was associated with a statistically significant improvement in return of spontaneous circulation or any process-focused outcome. Despite this, there was evidence of a system-wide improvement in phase 2, leading to improvements in return of spontaneous circulation (adjusted odds ratio, 1.87; 95% CI, 1.06-3.30; p=0.03) and process-focused outcomes. Implementation of real-time audiovisual feedback with or without postevent debriefing did not

We investigated whether installation of robot-assisted surgical equipment in hospitals resulted in concentration of the case loads of radical prostatectomy. We selected 11 areas with populations of around 1 million or more where there were one or more hospitals with robotic equipment and 4 or more without it. In addition, annual changes of case loads for prostatectomy over 4 years from 2010 to 2013 were clearly determined in these areas. The case loads were determined based on the results of a questionnaire survey for the hospitals with robots and on the Diagnostic Procedures Combination data provided by the Ministry of Health, Labor and Wealth for those without such equipment. The concentration of the case loads was principally defined as when hospitals with robots had more predominant proportion of cases than those without them in the comparison between case loads prior to instillation of robots (or in the initial year of the study) and those in the final years. The 11 selected areas included 44 hospitals with robots and 156 without them. Concentration of case loads was found in 5 areas. In 4 areas, installation of robots did not have a specific relation to the distribution pattern s of case loads in hospitals with or without the equipment. The remaining 2 areas tended to have a weak but not definite concentration of case loads. In the areas in which installation did not influence case loads the further analysis revealed that their case loads had already been concentrated in the initial year (2010) of the study. Although the current results were found in a single department of the hospital, robotic installation may result in concentration of prostatectomy case loads for such hospitals in some areas. The current results are intriguing when we consider the future roles of acute care hospitals and beds in our country where the number of aged patients having chronic diseases will increase. In conclusion, installation of robotic equipment may result in concentration

Background Difficult airway cases can quickly become emergencies, increasing the risk of life-threatening complications or death. Emergency airway management outside the operating room is particularly challenging. Methods We developed a quality improvement program—the Difficult Airway Response Team (DART)—to improve emergency airway management outside the operating room. DART was implemented by a team of anesthesiologists, otolaryngologists, trauma surgeons, emergency medicine physicians, and risk managers in 2005 at The Johns Hopkins Hospital in Baltimore, Maryland. The DART program had three core components: operations, safety, and education. The operations component focused on developing a multidisciplinary difficult airway response team, standardizing the emergency response process, and deploying difficult airway equipment carts throughout the hospital. The safety component focused on real-time monitoring of DART activations and learning from past DART events to continuously improve system-level performance. This objective entailed monitoring the paging system, reporting difficult airway events and DART activations to a web-based registry, and using in situ simulations to identify and mitigate defects in the emergency airway management process. The educational component included development of a multispecialty difficult airway curriculum encompassing case-based lectures, simulation, and team building/communication to ensure consistency of care. Educational materials were also developed for non-DART staff and patients to inform them about the needs of patients with difficult airways and ensure continuity of care with other providers after discharge. Results Between July 2008 and June 2013, DART managed 360 adult difficult airway events comprising 8% of all code activations. Predisposing patient factors included body mass index > 40, history of head and neck tumor, prior difficult intubation, cervical spine injury, airway edema, airway bleeding, and previous

Difficult airway cases can quickly become emergencies, increasing the risk of life-threatening complications or death. Emergency airway management outside the operating room is particularly challenging. We developed a quality improvement program-the Difficult Airway Response Team (DART)-to improve emergency airway management outside the operating room. DART was implemented by a team of anesthesiologists, otolaryngologists, trauma surgeons, emergency medicine physicians, and risk managers in 2005 at The Johns Hopkins Hospital in Baltimore, Maryland. The DART program had 3 core components: operations, safety, and education. The operations component focused on developing a multidisciplinary difficult airway response team, standardizing the emergency response process, and deploying difficult airway equipment carts throughout the hospital. The safety component focused on real-time monitoring of DART activations and learning from past DART events to continuously improve system-level performance. This objective entailed monitoring the paging system, reporting difficult airway events and DART activations to a Web-based registry, and using in situ simulations to identify and mitigate defects in the emergency airway management process. The educational component included development of a multispecialty difficult airway curriculum encompassing case-based lectures, simulation, and team building/communication to ensure consistency of care. Educational materials were also developed for non-DART staff and patients to inform them about the needs of patients with difficult airways and ensure continuity of care with other providers after discharge. Between July 2008 and June 2013, DART managed 360 adult difficult airway events comprising 8% of all code activations. Predisposing patient factors included body mass index >40, history of head and neck tumor, prior difficult intubation, cervical spine injury, airway edema, airway bleeding, and previous or current tracheostomy.

In order to study if tricyclic antidepressant drugs (TCA) in therapeutic doses increase the risk of death due to cardiovascular causes, the relative mortality from cardiovascular diseases was studied in two large groups of first hospitalized manic-depressive patients, one from the TCA era...... to the general population. Among 1133 such cases admitted between 1950 and 1956, the rate was 1.87. Our findings do not support the hypothesis that TCA contribute to the cardiovascular mortality in manic-depressives and even support suggestions that TCA treatment may lower the risk of death by cardiovascular...

Adiponectin is associated with obesity and insulin resistance. To date, there has been no genome-wide association study (GWAS) of adiponectin levels in Asians. Here we present a GWAS of a cohort of Korean volunteers. A total of 4,001 subjects were genotyped by using a genome-wide marker panel in a two-stage design (979 subjects initially and 3,022 in a second stage). Another 2,304 subjects were used for follow-up replication studies with selected markers. In the discovery phase, the top SNP associated with mean log adiponectin was rs3865188 in CDH13 on chromosome 16 (p = 1.69 × 10−15 in the initial sample, p = 6.58 × 10−39 in the second genome-wide sample, and p = 2.12 × 10−32 in the replication sample). The meta-analysis p value for rs3865188 in all 6,305 individuals was 2.82 × 10−83. The association of rs3865188 with high-molecular-weight adiponectin (p = 7.36 × 10−58) was even stronger in the third sample. A reporter assay that evaluated the effects of a CDH13 promoter SNP in complete linkage disequilibrium with rs3865188 revealed that the major allele increased expression 2.2-fold. This study clearly shows that genetic variants in CDH13 influence adiponectin levels in Korean adults. PMID:20887962

Upper gastrointestinal bleeding (UGIB) is a common emergency, with in-hospital mortality between 3 and 14%. However, the long-term mortality and causes of death are unknown. We investigated the long-term mortality and causes of death in UGIB patients in a retrospective single-centre case-control study design. A total of 569 consecutive patients, aged ≥18 years, admitted to Kuopio University Hospital for their first endoscopically verified UGIB during the years 2009-2011 were identified from hospital records. For each UGIB patient, an age, sex and hospital district matched control patient was identified from the Statistics Finland database. Data on endoscopy procedures, laboratory values, comorbidities and medication were obtained from patient records. Data on deaths and causes of death were obtained from Statistics Finland. In-hospital mortality of UGIB patients was low at 3.3%. The long-term (mean follow-up 32 months) mortality of UGIB patients was significantly higher than controls (34.1 versus 12.1%, p death compared to controls was highest (HR 19.2, 95% CI 7.0-52.4, p causes of death were related to comorbidities and did not differ from causes of death in controls. UGIB patients have three times higher long-term mortality than population controls.

Effects of patient death on nursing staff: a literature review.

Science.gov (United States)

Wilson, Janet; Kirshbaum, Marilyn

There were 509090 deaths recorded in England and Wales for 2008 (Office for National Statistics, 2010); of these, over 56% (260000) occurred in NHS hospitals. The death of a patient is an event that most, if not all, nursing staff will encounter during their work. This experience can elicit physical, cognitive, behavioural, spiritual and emotional responses (Parkes, 1998). The aim of this literature review is to explore how the death of patients in a hospital setting impact on nursing staff. A review of the literature was undertaken using the online databases CINAHL, Medline and PsychInfo. The search was limited to articles in the English language and those from peer-reviewed journals. Themes arising from the literature review included: the theoretical context; the emotional impact; the culture of the healthcare setting; staff's previous life experiences; and support available for healthcare staff. The death of patients does have an impact on nurses. This can affect them both in their work environment and outside of work. Education around grief theory and support from others are helpful for staff in developing strategies for coping with patient deaths.

The objective is to present the causes of late death in patients subjected to liver transplantation. A total of 209 patients were subjected to 223 liver transplantations (14 retransplantations). The computerized study protocol sheets were evaluated to determine the causes of late death (> 6 months after transplantation). Of the 209 patients, 30 had late death. Ductopenic rejection (chronic rejection) was the most common cause and it was observed in 10 patients. Time after transplantation at the moment of death of this group of patients varied from 11 to 57 months, with an average of 29 months. Seven patients died at the hospital admission of hepatic retransplantation. Other causes of late death were sepsis, lymphoproliferative disease, chronic renal insufficiency, and hepatic insufficiency. The most common cause of late death after liver transplantation is ductopenic rejection, followed by complications of retransplantation and sepsis. Death owing to ductopenic rejection may occur even many years after transplantation.

Full Text Available Abstract Background Maternal mortality in Kinshasa is high despite near universal availability of antenatal care and hospital delivery. Possible explanations are poor-quality care and by delays in the uptake of care. There is, however, little information on the circumstances surrounding maternal deaths. This study describes and compares the circumstances of survivors and non survivors of severe obstetric complications. Method Semi structured interviews with 208 women who survived their obstetric complication and with the families of 110 women who died were conducted at home by three experienced nurses under the supervision of EK. All the cases were identified from twelve referral hospitals in Kinshasa after admission for a serious acute obstetric complication. Transcriptions of interviews were analysed with N-Vivo 2.0 and some categories were exported to SPSS 14.0 for further quantitative analysis. Results Testimonies showed that despite attendance at antenatal care, some women were not aware of or minimized danger signs and did not seek appropriate care. Cost was a problem; 5 deceased and 4 surviving women tried to avoid an expensive caesarean section by delivering in a health centre, although they knew the risk. The majority of surviving mothers (for whom the length of stay was known had the caesarean section on the day of admission while only about a third of those who died did so. Ten women died before the required caesarean section or blood transfusion could take place because they did not bring the money in time. Negligence and lack of staff competence contributed to the poor quality of care. Interviews revealed that patients and their families were aware of the problem, but often powerless to do anything about it. Conclusion Our findings suggest that women with serious obstetric complications have a greater chance of survival in Kinshasa if they have cash, go directly to a functioning referral hospital and have some leverage when dealing

Presenting the results of 5 years of implementing health facility-based maternal death audits in Rwanda, showing maternal death classification, identification of substandard (care) factors that have contributed to death, and conclusive recommendations for quality improvements in maternal and obstetric care. Nationwide facility-based retrospective cohort study. All cases of maternal death audited by district hospital-based audit teams between January 2009 and December 2013 were reviewed. Maternal deaths that were not subjected to a local audit are not part of the cohort. 987 audited cases of maternal death. Characteristics of deceased women, timing of onset of complications, place of death, parity, gravida, antenatal clinic attendance, reported cause of death, service factors and individual factors identified by committees as having contributed to death, and recommendations made by audit teams. 987 cases were audited, representing 93.1% of all maternal deaths reported through the national health management information system over the 5-year period. Almost 3 quarters of the deaths (71.6%) occurred at district hospitals. In 44.9% of these cases, death occurred in the post-partum period. Seventy per cent were due to direct causes, with post-partum haemorrhage as the leading cause (22.7%), followed by obstructed labour (12.3%). Indirect causes accounted for 25.7% of maternal deaths, with malaria as the leading cause (7.5%). Health system failures were identified as the main responsible factor for the majority of cases (61.0%); in 30.3% of the cases, the main factor was patient or community related. The facility-based maternal death audit approach has helped hospital teams to identify direct and indirect causes of death, and their contributing factors, and to make recommendations for actions that would reduce the risk of reoccurrence. Rwanda can complement maternal death audits with other strategies, in particular confidential enquiries and near-miss audits, so as to

OZONE CONCENTRATION ATTRIBUTABLE PREMATURE DEATH IN POLAND

Full Text Available Ozone in the lower part of the atmosphere (troposphere, strong photochemical oxidant, is not directly emitted to the atmosphere but formed through a series of complex reactions. Ozone concentrations depends on ozone precursors air contamination (mainly nitrogen dioxide and non-methane volatile organic compounds and meteorological conditions (temperature and solar radiation. The main sectors emitted ozone precursors are road transport, power and heat generation plants, household (heating, industry, and petrol storage and distribution. Ozone and some of its precursors are also transported long distances in the atmosphere and are therefore considered a transboundary problem. As a result, the ozone concentrations are often low in busy urban areas and higher in suburban and rural areas. Nowadays, instead of particulate matter, ozone is one of the most widespread global air pollution problems. In and around urban areas, relatively large gradients of ozone can be observed. Because of its high reactivity in elevated concentrations ozone causes serious health problems and damage to ecosystems, agricultural crops and materials. Main ill-health endpoints as a results of ozone concentrations can be characterised as an effect of pulmonary and cardiovascular system, time morbidity and mortality series, development of atherosclerosis and asthma and finally reduction in life expectancy. The associations with increased daily mortality due to ozone concentrations are confirmed by many researches and epidemiological studies. Estimation of the level selected ill-health endpoints (mortality in total and due to cardiovascular and respiratory causes as a result of the short-term ozone exposure in Poland was the main aim of the project. Final results have been done based on estimation method elaborated by WHO, ozone measurements from National Air Quality Monitoring System and statistical information such as mortality rate and populations. All analysis have been done in

Currently, dengue fever, chikungunya fever, and zika virus represent serious public health issues in Brazil, despite efforts to control the vector, the Aedes aegypti mosquito. This was a descriptive and ecological study of dengue deaths occurring from 2002 to 2013 in São Luis, Maranhão, Brazil. Geoprocessing software was used to draw maps, linking the geo-referenced deaths with urban/social data at census tract level. There were 74 deaths, concentrated in areas of social vulnerability. The use of geo-technology tools pointed to a concentration of dengue deaths in specific intra-urban areas.

Full Text Available When the patients are in the end-of-life, the cares would focus to favor a good death, for that reason the nursing staff must know how to integrate the death like a part of the life, being avoided that produces anxiety to them before the possibility of taking part its own fears to the death. The core of nursing staff in intensive care units is to maintain life of their patients, reason why the end-of life in them is not easy or natural.Objective: Evaluate the death anxiety levels in intensive care nursing staff.Material and method: An observational study was conducted descriptive cross hospital adult and Paediatric ICU General University Gregorio Marañón Hospital, through survey to nurses and auxiliary nurses of those units.The anxiety inventory was used to Death (Death Anxiety Inventory [DAI] for the assessment of anxiety before death. Outcomes: Paediatric ICU nurses have higher levels of anxiety that the adult ICU as well as the less experienced professionals and those declared not feel trained in the subject.Conclusions: Experience and the training are key elements that help professionals face to death, from management we must ensure that patients in stage terminal are served by professionals with this profile.

Determination of Death and the Dead Donor Rule: A Survey of the Current Law on Brain Death

Despite seeming uniformity in the law, end-of-life controversies have highlighted variations among state brain death laws and their interpretation by courts. This article provides a survey of the current legal landscape regarding brain death in the United States, for the purpose of assisting professionals who seek to formulate or assess proposals for changes in current law and hospital policy. As we note, the public is increasingly wary of the role of organ transplantation in determinations of death, and of the variability of brain death diagnosing criteria. We urge that any attempt to alter current state statutes or to adopt a national standard must balance the need for medical accuracy with sound ethical principles which reject the utilitarian use of human beings and are consistent with the dignity of the human person. Only in this way can public trust be rebuilt. PMID:27097648

The first case of Chikungunya virus in Honduras was identified in 2014. The virus has spread widely across Honduras via the Aedes aegypti mosquito, leading to an outbreak of Chikungunya virus (CHIKV) in 2015 that significantly impacted children. A retrospective chart review of 235 children diagnosed with CHIKV and admitted to the National Autonomous University of Honduras Hospital Escuela (Hospital Escuela) in Tegucigalpa, Honduras, was accomplished with patients who were assessed for clinical features and neurologic complications. Of 235 children admitted to Hospital Escuela with CHIKV, the majority had symptoms of fever, generalized erythematous rash, and irritability. Fourteen percent had clinical arthritis. Ten percent of patients had seizures. Six percent had meningoencephalitis. There were 2 childhood deaths during the course of this study, one from meningoencephalitis and another from myocarditis. Chikungunya virus can cause severe complications in children, the majority of which impact the central nervous system.

Purpose: To demonstrate that the authors’ new “aqueous solution vs pure water” equation to calculate osmotic potential may be used to calculate the osmotic potentials of inorganic and organic aqueous solutions over wide ranges of solute concentrations and temperatures. Currently, the osmotic potentials of solutions used for medical purposes are calculated from equations based on the thermodynamics of the gas laws which are only accurate at low temperature and solute concentration levels. Some solutions used in medicine may need their osmotic potentials calculated more accurately to take into account solute concentrations and temperatures. Methods: The authors experimented with their new equation for calculating the osmotic potentials of inorganic and organic aqueous solutions up to and beyond body temperatures by adjusting three of its factors; (a) the volume property of pure water, (b) the number of “free” water molecules per unit volume of solution, “N{sub f},” and (c) the “t” factor expressing the cooperative structural relaxation time of pure water at given temperatures. Adequate information on the volume property of pure water at different temperatures is available in the literature. However, as little information on the relative densities of inorganic and organic solutions, respectively, at varying temperatures needed to calculate N{sub f} was available, provisional equations were formulated to approximate values. Those values together with tentative t values for different temperatures chosen from values calculated by different workers were substituted into the authors’ equation to demonstrate how osmotic potentials could be estimated over temperatures up to and beyond bodily temperatures. Results: The provisional equations formulated to calculate N{sub f}, the number of free water molecules per unit volume of inorganic and organic solute solutions, respectively, over wide concentration ranges compared well with the calculations of N{sub f

Aspecific scoring systems are used to predict the risk of death postsurgery in patients with infective endocarditis (IE). The purpose of the present study was both to analyze the risk factors for in-hospital death, which complicates surgery for IE, and to create a mortality risk score based on the results of this analysis. Outcomes of 361 consecutive patients (mean age, 59.1±15.4 years) who had undergone surgery for IE in 8 European centers of cardiac surgery were recorded prospectively, and a risk factor analysis (multivariable logistic regression) for in-hospital death was performed. The discriminatory power of a new predictive scoring system was assessed with the receiver operating characteristic curve analysis. Score validation procedures were carried out. Fifty-six (15.5%) patients died postsurgery. BMI >27 kg/m 2 (odds ratio [OR], 1.79; P =0.049), estimated glomerular filtration rate 55 mm Hg (OR, 1.78; P =0.032), and critical state (OR, 2.37; P =0.017) were independent predictors of in-hospital death. A scoring system was devised to predict in-hospital death postsurgery for IE (area under the receiver operating characteristic curve, 0.780; 95% CI, 0.734-0.822). The score performed better than 5 of 6 scoring systems for in-hospital death after cardiac surgery that were considered. A simple scoring system based on risk factors for in-hospital death was specifically created to predict mortality risk postsurgery in patients with IE. © 2017 The Authors.

2017-01-01

Background: Death is a natural and frightening phenomenon, which is inevitable. Previous studies on death, which presented a negative and tedious image of this process, are now being revised and directed towards acceptable death and good death. One of the proposed terms about death and dying is "healthy death", which encourages dealing with death positively and leading a lively and happy life until the last moment. This study aimed to explain the views of Iranians about the elements of healthy death. Methods: This qualitative study was conducted for 12 months in two general hospitals in Tehran (capital of Iran), using the thematic analysis method. After conducting 23 in-depth interviews with 21 participants, transcription of content, and data immersion and analysis, themes, as the smallest meaningful units were extracted, encoded and classified. Results: One main category of healthy death with 10 subthemes, including dying at the right time, dying without hassle, dying without cost, dying without dependency and control, peaceful death, not having difficulty at dying, not dying alone and dying at home, inspired death, preplanned death, and presence of a clergyman or a priest, were extracted as the elements of healthy death from the perspective of the participants in this study. Conclusion: The study findings well explained the elements of healthy death. Paying attention to the conditions and factors causing healthy death by professionals and providing and facilitating quality services for patients in the end stage of life make it possible for patients to experience a healthy death.

Studies have shown that there is no safe level of secondhand smoke (SHS) exposure and there is a close link between SHS and the risk of coronary heart disease and stroke. Carbon monoxide (CO) is one of the most important components present in SHS. To evaluate the impact of the smoking ban law in the city of Sao Paulo, Brazil, on the CO concentration in restaurants, bars, night clubs and similar venues and in their workers. In the present study we measured CO concentration in 585 hospitality venues. CO concentration was measured in different environments (indoor, semi-open and open areas) from visited venues, as well as, in the exhaled air from approximately 627 workers of such venues. Measurements were performed twice, before and 12 weeks after the law implementation. In addition, the quality of the air in the city during the same period of our study was verified. RESULTS The CO concentration pre-ban and pot-ban in hospitality venues was indoor area 4.57 (3.70) ppm vs 1.35 (1.66) ppm (phospitality venues and in their workers, whether they smoke or not.

To investigate the association, if any, between child mortality and distance to the nearest hospital. The study was based on data from a 1-year study of the cause of illness in febrile paediatric admissions to a district hospital in north-east Tanzania. All villages in the catchment population were geolocated, and travel times were estimated from availability of local transport. Using bands of travel time to hospital, we compared admission rates, inpatient case fatality rates and child mortality rates in the catchment population using inpatient deaths as the numerator. Three thousand hundred and eleven children under the age of 5 years were included of whom 4.6% died; 2307 were admitted from time between admission and death. Assuming uniform mortality in the catchment population, the predicted number of deaths not benefiting from hospital admission prior to death increased by 21.4% per hour of travel time to hospital. If the same admission and death rates that were found at <3 h from the hospital applied to the whole catchment population and if hospital care conferred a 30% survival benefit compared to home care, then 10.3% of childhood deaths due to febrile illness in the catchment population would have been averted. The mortality impact of poor access to hospital care in areas of high paediatric mortality is likely to be substantial although uncertainty over the mortality benefit of inpatient care is the largest constraint in making an accurate estimate. © 2014 The Authors Tropical Medicine & International Health Published by John Wiley & Sons Ltd.

Several studies have examined the incidence and mortality of stroke in relation to season. However, the evidence is conflicting partly due to variation in the populations (community vs. hospital-based), and in climatic conditions between studies. Moreover, they may not have been able to take into account the age, sex and stroke type of the study population. We hypothesized that the age, sex and type of stroke are major determinants of the presence or absence of winter excess in morbidity and mortality associated with stroke. We analyzed a hospital-based stroke register from Norfolk, UK to examine our prior hypothesis. Using Curwen's method, we performed stratified sex-specific analyses by (1) seasonal year and (2) quartiles of patients' age and stroke subtype and calculated the winter excess for the number of admissions, in-patient deaths and length of acute hospital stay. There were 5,481 patients (men=45%). Their ages ranged from 17 to 105 years (median=78 years). There appeared to be winter excess in hospital admissions, deaths and length of acute hospital stay overall accounting for 3/100,000 extra admissions (winter excess index of 3.4% in men and 7.6% in women) and 1/100,000 deaths (winter excess index of 4.7 and 8.6% in women) due to stroke in winter compared to non-winter periods. Older patients with non-haemorrhagic stroke mainly contribute to this excess. If our findings are replicated throughout England and Wales, it is estimated that there are 1,700 excess admissions, 600 excess in-patient deaths and 24,500 extra acute hospital bed days each winter, related to stroke within the current population of approximately 60 million. Further research should be focused on the determinants of winter excess in morbidity and mortality associated with stroke. This may subsequently reduce the morbidity and mortality by providing effective preventive strategies in future. (c) 2007 S. Karger AG, Basel.

The volatility of financial markets may cause substantial emotional and physical stress among investors. We hypothesize that this may have adverse effects on cardiovascular health. The Chinese stock markets were extremely volatile between 2006 and 2008. We, therefore, examined the relationship between daily change of the Shanghai Stock Exchange (SSE) Composite Index (referred as the Index) and coronary heart disease (CHD) deaths from 1 January 2006 to 31 December 2008 in Shanghai, the financial capital of China. Daily death and stock performance data were collected from the Shanghai Center for Disease Control and Prevention and SSE, respectively. Data were analysed with over-dispersed generalized linear Poisson models, controlling for long-term and seasonal trends of CHD mortality, day of the week, Index closing value, weather conditions, and air pollution levels. We observed a U-shaped relationship between the Index change and CHD deaths: both rising and falling of the Index were associated with more deaths and the fewest deaths coincided with little or no change of the index. We also examined the absolute daily change of the Index in relation to CHD deaths: in a 1-day lag model, each 100-point change of the Index corresponded to 5.17% (95% confidence interval: 1.71, 8.63%) increase in CHD deaths. Further analysis showed that the association was stronger for out-of-hospital CHD death than for in-hospital death. We found that CHD deaths fluctuated with daily stock changes in Shanghai, suggesting that stock volatility may adversely affect cardiovascular health.

Full Text Available Abstract Background Despite the significant reduction in childhood mortality, neonatal mortality has shown little or no concomitant decline worldwide. The dilemma arises in that the lack of documentation of cause of death in developing countries, where registration of vital events is virtually nonexistent. Understanding of the causes of death in neonates is important to guide public health interventions. The present study identifies the common causes of neonatal death in Ethiopia. Methods A prospective cohort study was conducted among neonates born between April 2014 and July 2014 in seven hospitals, in Tigray region, Ethiopia. Mothers were interviewed by midwifes respecting risk factors and infant survival. For neonates who died in hospital, causes of death were extracted from medical records, whereas a verbal autopsy method provided presumptive assignment of cause of death for those infants who died at home. Results Of the1152 live births, there were 68 deaths (63 per 1000 live births. Two thirds of deaths were attributable to prematurity 23 (34% or asphyxia 21 (31%. Slight variance was seen between the morality patterns in early and late neonatal periods. In the early neonatal period, 37% were due to prematurity, while asphyxia (35% was more common in the late neonatal period. All infection-related deaths occurred in neonate-mother dyads from rural areas. Conclusion Prematurity, asphyxia, and infections were the leading causes of neonatal deaths in Tigray region during the study period. Causes of deaths identified during early and late neonatal mortality differed, which clearly indicates the need for responsive and evidence-based interventions and policies.

BACKGROUND: In the United States, drowning is the second leading cause of unintentional injury death in children aged 1 to 19 years, accounting for nearly 1100 deaths per year. Although a decline in overall fatal drowning deaths among children has been noted, national trends and disparities in pediatric drowning hospitalizations have not been reported. METHODS: To describe trends in pediatric drowning in the United States and provide national benchmarks for state and regional comparisons, we analyzed existing data (1993–2008) from the Nationwide Inpatient Sample, the largest, longitudinal, all-payer inpatient care database in the United States. Children aged 0 to 19 years were included. Annual rates of drowning-related hospitalizations were determined, stratified by age, gender, and outcome. RESULTS: From 1993 to 2008, the estimated annual incidence rate of pediatric hospitalizations associated with drowning declined 49% from 4.7 to 2.4 per 100 000 (P drowning hospitalization declined from 0.5 (95% confidence interval, 0.4–0.7) deaths per 100 000 in 1993–1994 to 0.3 (95% confidence interval, 0.2–0.4) in 2007–2008 (P drowning have decreased over the past 16 years. Our study provides national estimates of pediatric drowning hospitalization that can be used as benchmarks to target and assess prevention strategies. PMID:22250031

Medical audit is a widely promoted strategy in hospitals, but experience within community settings is scant. Community neonatal death audit is a form of audit, which involves a systematic analysis of the quality of care provided in the home, danger sign recognition and care seeking decision making for neonatal illness. This research was conducted in Uttar Pradesh, India, to investigate the feasibility and cultural acceptability of community neonatal death audits. During November-December 2004, we conducted three in-depth interviews with family members of deceased neonates, and six focus group discussions with family and community members. Three approaches were evaluated: in-depth interview with the family before engaging them in an audit with the community; preliminary meeting to build rapport with the family and community before conducting an audit; and audit with the family and community in a single focus group. Approaches were interactive processes, involving the community, to identify avoidable factors in a particular death and discuss solutions. Carried out in a culturally sensitive and non-punitive manner, community neonatal death audit was found to be acceptable and feasible. All approaches provoked formal investigation by community members, and stimulated sharing of views, leading to the self-discovery that community perception was a cumulatively amplified effect of individual perceptions. Presence of an educated/experienced community member or health worker served as a catalyst. No one optimal approach was identified. Community neonatal audit is an acceptable approach that shows promise as an effective intervention for improving neonatal health outcomes.

Full Text Available Abstract: INTRODUCTION Currently, dengue fever, chikungunya fever, and zika virus represent serious public health issues in Brazil, despite efforts to control the vector, the Aedes aegypti mosquito. METHODS: This was a descriptive and ecological study of dengue deaths occurring from 2002 to 2013 in São Luis, Maranhão, Brazil. Geoprocessing software was used to draw maps, linking the geo-referenced deaths with urban/social data at census tract level. RESULTS: There were 74 deaths, concentrated in areas of social vulnerability. CONCLUSIONS: The use of geo-technology tools pointed to a concentration of dengue deaths in specific intra-urban areas.

To examine differences in outcomes between planned home births, occurring at home or in hospital, and planned hospital births. Population-based study using South Australian perinatal data on all births and perinatal deaths during the period 1991-2006. Analysis included logistic regression adjusted for predictor variables and standardised perinatal mortality ratios. Perinatal death, intrapartum death, death attributed to intrapartum asphyxia, Apgar score home births accounted for 0.38% of 300,011 births in South Australia. They had a perinatal mortality rate similar to that for planned hospital births (7.9 v 8.2 per 1000 births), but a sevenfold higher risk of intrapartum death (95% CI, 1.53-35.87) and a 27-fold higher risk of death from intrapartum asphyxia (95% CI, 8.02-88.83). Review of perinatal deaths in the planned home births group identified inappropriate inclusion of women with risk factors for home birth and inadequate fetal surveillance during labour. Low Apgar scores were more frequent among planned home births, and use of specialised neonatal care as well as rates of postpartum haemorrhage and severe perineal tears were lower among planned home births, but these differences were not statistically significant. Planned home births had lower caesarean section and instrumental delivery rates, and a seven times lower episiotomy rate than planned hospital births. Perinatal safety of home births may be improved substantially by better adherence to risk assessment, timely transfer to hospital when needed, and closer fetal surveillance.

"Death with dignity" in the Japanese context.

Science.gov (United States)

Shimoda, Motomu

In Japan, "death with dignity" is a widely known term that is distinguished from "euthanasia." It is generally defined as "the act of letting a terminally ill or a patient in a persistent vegetative state die by withdrawing life-sustaining treatment on request in the form of a living will." Most Japanese people consider death with dignity a desirable way of terminating one's life and it is therefore acceptable as a "natural death" or "humane death." Originally, death with dignity was regarded as a passive intervention, but since the 1990s, its connotations have changed in western countries; people claim that voluntary active euthanasia and physician-assisted suicide should be legalized as death with dignity or the "right to die." In this paper, I examine the points and problems of this new type of death with dignity and propose an alternative version of death with dignity especially for the Japanese context, i.e. the end-of-life care process in support of terminal living with dignity.

Full Text Available Abstract Background Hyperglycemia in hospitalized patients is known to be related to a higher incidence of clinical and surgical complications and poorer outcomes. Adequate glycemic control and earlier diagnosis of type 2 diabetes during hospitalization are cost-effective measures. Methods This prospective cohort study was designed to determine the impact of hyperglycemia on morbidity and mortality in a general hospital setting during a 3-month period by reviewing patients' records. The primary purposes of this trial were to verify that hyperglycemia was diagnosed properly and sufficiently early and that it was managed during the hospital stay; we also aimed to evaluate the relationship between in-hospital hyperglycemia control and outcomes such as complications during the hospital stay, extent of hospitalization, frequency of re-hospitalization, death rates and number of days in the ICU (Intensive Care Unit after admission. Statistical analyses utilized the Kruskall-Wallis complemented by the "a posteriori" d.m.s. test, Spearman correlation and Chi-squared test, with a level of significance of 5% (p Results We reviewed 779 patient records that fulfilled inclusion criteria.

Hand hygiene is an important and basic practice that should be used by all healthcare staff to protect both themselves and their patients against infection. Unfortunately hand hygiene compliance remains poor. To show an improvement in hand hygiene compliance using a multifaceted approach. This was a quasiexperimental pre-post intervention study design with a number of standardised interventions to promote hand hygiene. The World Health Organization hand hygiene multimodal (five-step) intervention approach was used. The study ran from June 2015 to August 2015 in 11 selected wards of a 975-bed tertiary and quaternary care public hospital (Groote Schuur Hospital, Cape Town, South Africa). The outcome was to assess improvement in hand hygiene compliance monthly over the 3 months, compared with non-intervention wards and compared with the wards' own performance measured in 2014. The study included both descriptive and analytical components. Post intervention, hand hygiene compliance showed a statistically significant improvement for before patient contact from 34% in 2014 to 76% in 2015 (p<0.05) and for after patient contact from 47% in 2014 to 82% in 2015 (p<0.05). The intervention improved hand hygiene compliance and can easily be replicated in other wards, resulting in sustaining a culture of hand hygiene improvement and behavioural change throughout the hospital.

Referring to our experience with post-mortem computed tomography (CT), many hypothermic death cases presented a lack of increase in lung-field concentration, blood clotting in the heart, thoracic aorta or pulmonary artery, and urine retention in the bladder. Thus we evaluated the diagnostic performance of post-mortem CT on hypothermic death based on the above-mentioned three findings. Twenty-four hypothermic death subjects and 53 non-hypothermic death subjects were examined. Two radiologists assessed the presence or lack of an increase in lung-field concentration, blood clotting in the heart, thoracic aorta or pulmonary artery, and measured urine volume in the bladder. Pearson's chi-square test and Mann–Whitney U-test were used to assess the relationship between the three findings and hypothermic death. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of the diagnosis were also calculated. Lack of an increase in lung-field concentration and blood clotting in the heart, thoracic aorta or pulmonary artery were significantly associated with hypothermic death (p = 0.0007, p < 0.0001, respectively). The hypothermic death cases had significantly more urine in the bladder than the non-hypothermic death cases (p = 0.0011). Regarding the diagnostic performance with all three findings, the sensitivity was 29.2% but the specificity was 100%. These three findings were more common in hypothermic death cases. Although the sensitivity was low, these findings will assist forensic physicians in diagnosing hypothermic death since the specificity was high.

Children who receive in-hospital treatment of severe acute malnutrition often have high mortality rates, and the reasons are not well understood. We assessed risk factors for death in children who were treated for malnutrition in a hospital. In a prospective observational study of 120 children who were receiving in-hospital treatment of severe acute malnutrition in Uganda with therapeutic formulas F-75 and F-100, we collected data on symptoms, clinical findings, plasma markers of refeeding syndrome (electrolytes and phosphate), and acute phase reactants, and recorded the nutritional therapy given in hospital. Seventeen children (14%) died. Clinical risk factors for death were the presence of oral thrush (HR: 5.0; 95% CI: 1.6, 15.2), a caretaker-reported severity of illness on a visual analog scale (HR: 1.7; 95% CI: 1.1, 2.6), impaired consciousness (HR: 16.7; 95% CI: 3.1, 90.4), and a capillary refill time >2 s (HR: 3.9; 95% CI: 1.4, 11.3). HIV infection was not associated with mortality (HR: 3.0; 95% CI: 0.7, 12.4), which was most likely due to low power. Biochemical risk factors were a plasma C-reactive protein concentration >15 mg/L on admission and low plasma phosphate that was measured on day 2 (HR: 8.7; 95% CI: 2.5, 30.1), particularly in edematous children. The replacement of F-75 with unfortified rice porridge to ameliorate diarrhea was associated with a higher risk of death, particularly if given during the first 2 d (HR: 5.0; 95% CI: 1.9, 13.3), which was an association that remained after adjustment for potential confounders (HR: 69.5; 95% CI: 7.0, 694.6). Refeeding syndrome may occur in children who are treated for malnutrition, even with moderately low plasma phosphate, and, in particular, in children with edematous malnutrition. The replacement of F-75 with unfortified rice porridge is associated with increased risk of death, which is possibly mediated by lowering plasma phosphate. The identified clinical risk factors may potentially improve the

Upper gastrointestinal (GI) diseases are common, but there is a paucity of data describing variations by ethnic group and so a lack of understanding of potential health inequalities. We studied the incidence of specific upper GI hospitalization and death by ethnicity in Scotland. Using the Scottish Health and Ethnicity Linkage Study, linking NHS hospitalizations and mortality to the Scottish Census 2001, we explored ethnic differences in incidence (2001-10) of oesophagitis, peptic ulcer disease, gallstone disease and pancreatitis. Relative Risks (RRs) and 95% confidence intervals were calculated using Poisson regression, multiplied by 100, stratified by sex and adjusted for age, country of birth (COB) and socio-economic position. The White Scottish population (100) was the reference population. Ethnic variations varied by outcome and sex, e.g. adjusted RRs (95% confidence intervals) for oesophagitis were comparatively higher in Bangladeshi women (209; 124-352) and lower in Chinese men (65; 51-84) and women (69; 55-88). For peptic ulcer disease, RRs were higher in Chinese men (171; 131-223). Pakistani women had higher RRs for gallstone disease (129; 112-148) and pancreatitis (147; 109-199). The risks of upper GI diseases were lower in Other White British and Other White [e.g. for peptic ulcer disease in men, respectively (74; 64-85) and (81; 69-94)]. Risks of common upper GI diseases were comparatively lower in most White ethnic groups in Scotland. In non-White groups, however, risk varied by disease and ethnic group. These results require consideration in health policy, service planning and future research. © The Author 2015.

Profile of sudden death in an adult population (1999-2008).

LENUS (Irish Health Repository)

Downes, M R

2010-06-01

Sudden death is the sudden and unexpected death of an individual within 24 hours of symptom onset. The vast majority of these cases are found, at autopsy, to be due to underlying ischaemic cardiac disease. We retrospectively reviewed all adult post mortems performed at Beaumont Hospital over a decade (1999-2008). Our aim was to identify all sudden death cases (natural and accidental) and subclassify them according to age profile and organ system involved. We identified 1230 sudden death cases in the review period with 775 (63%) deaths attributable to ischaemic heart disease. The rate of sudden death remained constant over the decade with 663 (54%) deaths occurring in the first five years. Our negative autopsy rate was 2.8% corresponding to 35 cases. This is the first Irish study to retrospectively review all adult sudden deaths within a defined catchment area and analyse them as outlined above.

US death certificate data in Surveillance, Epidemiology, and End Results Stat 8.2.1 were used to categorize cancer patient death as being due to index-cancer, nonindex-cancer, and noncancer cause from 1973 to 2012. In addition, data were characterized with standardized mortality ratios (SMRs), which provide the relative risk of death compared with all persons. The greatest relative decrease in index-cancer death (generally from > 60% to deaths were stable (typically >40%) among patients with cancers of the liver, pancreas, esophagus, and lung, and brain. Noncancer causes of death were highest in patients with cancers of the colorectum, bladder, kidney, endometrium, breast, prostate, testis; >40% of deaths from heart disease. The highest SMRs were from nonbacterial infections, particularly among 1,000 for lymphomas, P death from index- and nonindex-cancers varies widely among primary sites. Risk of noncancer deaths now surpasses that of cancer deaths, particularly for young patients in the year after diagnosis. © The Author 2016.

Objective. This study examined the association between serum albumin concentration and ketosis risk in hospitalized individuals with type 2 diabetes mellitus (T2DM). Methods. A retrospective cross-sectional study was conducted at a medical center in Taiwan. Inclusion criteria were endocrinology ward inpatients exceeding 21 years of age, with preexisting diagnosis of T2DM, and blood glucose above 13.9 millimoles per liter (mmol/L) at admission. Individuals without measurement of serum albumin, urine ketone, or hemoglobin A1C, or harboring active infection, myocardial infarction, cerebrovascular event, cirrhosis, malignancy, or overt proteinuria were excluded. Using serum albumin concentration below 3.0 grams per deciliter to define hypoalbuminemia, 151 hypoalbuminemic cases and 104 normoalbuminemic controls were enrolled. The presence of ketones in urine established ketosis. Results. The prevalence of ketonuria was 48% in hypoalbuminemic subjects compared to 30% in normoalbuminemic controls (odds ratio (OR): 2.15; 95% confidence interval (CI): 1.26-3.57; P = 0.004). Moreover, among the 156 subjects with serum beta-hydroxybutyrate measurement in addition to urine ketone, 33% of the hypoalbuminemic individuals had ketonemia exceeding 3 mmol/L compared to 19% of those with normoalbuminemia (OR: 2.12, 95% CI: 0.99-4.48, P = 0.051). Conclusions. Serum albumin concentration is inversely associated with ketosis risk in hospitalized individuals with T2DM.

Full Text Available Abstract Background There is limited data on adolescent mortality particularly from developing countries with unreliable death registration systems. This calls for the use of other sources of data to ascertain cause of adolescent mortality. The objective of this study was to describe the causes of death among Ghanaian adolescents 10 to 19 years in Accra, Ghana utilizing data from autopsies conducted in Korle Bu Teaching Hospital (KBTH. Findings Out of the 14,034 autopsies carried out from 2001 to 2003 in KBTH, 7% were among adolescents. Of the 882 deaths among adolescents analyzed, 402 (45.6% were females. There were 365 (41.4% deaths from communicable disease, pregnancy related conditions and nutritional disorders. Non-communicable diseases accounted for 362 (41% cases and the rest were attributable to injuries and external causes of morbidity and mortality. Intestinal infectious diseases and lower respiratory tract infections were the most common communicable causes of death collectively accounting for 20.5% of total deaths. Death from blood diseases was the largest (8.5% among the non-communicable conditions followed by neoplasms (7%. Males were more susceptible to injuries than females (χ2 = 13.45, p = .000. At least five out of ten specific causes of death were as a result of infections with pneumonia and typhoid being the most common. Sickle cell disease was among the top three specific causes of death. Among the females, 27 deaths (6.7% were pregnancy related with most of them being as a result of abortion. Conclusions The autopsy data from the Korle-Bu Teaching Hospital can serve as a useful source of information on adolescent mortality. Both communicable and non-communicable diseases accounted for most deaths highlighting the need for health care providers to avoid complacency in their management of adolescents presenting with these diseases.

Background Studies have shown that there is no safe level of secondhand smoke (SHS) exposure and there is a close link between SHS and the risk of coronary heart disease and stroke. Carbon monoxide (CO) is one of the most important components present in SHS. Objective To evaluate the impact of the smoking ban law in the city of Sao Paulo, Brazil, on the CO concentration in restaurants, bars, night clubs and similar venues and in their workers. Methods In the present study we measured CO concentration in 585 hospitality venues. CO concentration was measured in different environments (indoor, semi-open and open areas) from visited venues, as well as, in the exhaled air from approximately 627 workers of such venues. Measurements were performed twice, before and 12 weeks after the law implementation. In addition, the quality of the air in the city during the same period of our study was verified. Results The CO concentration pre-ban and pot-ban in hospitality venues was indoor area 4.57 (3.70) ppm vs 1.35 (1.66) ppm (phospitality venues and in their workers, whether they smoke or not.

2011-02-27

As donation after cardiac death practices expand, the number of institutional policies is increasing. We contacted organ procurement organizations throughout the United States and requested protocols in hospitals in their donor service areas. Sixty-four protocols were obtained with representation from 16 different states. The terminology and recommended practices varied substantially. The methods for death determination were not specified in 28 (44%) protocols. Most adhered to a 2- to 5-min observation time between circulatory arrest and organ procurement, but 10 (16%) provided no information. This variability reveals a need to define a uniform standard in donation after cardiac death protocols and death determination practices.

2007-01-01

To assess the magnitude, causes and substandard care factors responsible for the third delay of maternal mortality seen in our unit III, Department of Obstetrics and Gynecology, Civil Hospital, Karachi. This Cross-sectional, retrospective study was carried out on 152 mothers who died over a period of eight years from 1997 to 2004 at Civil Hospital Karachi. Death summaries of all maternal deaths were reviewed from death registers and were studied for substandard care factors which could have been responsible for the third delay of maternal mortality. The frequency of maternal mortality was 1.3 per 100 deliveries. The mean age was 29+-6.49 years and mean parity was 3.24+-3.25. The main causes of death were hypertensive disorders in 52/152 (34.21%), hemorrhage in 40/152 (26.31%), unsafe abortion in 16/152 (10.52%), puerperal sepsis in 14/152 (9.21%) and obstructed labor in 11/152 (7.2%) cases. Substandard care factors were present in 76.7% of patients, which included inappropriate management of pulmonary edema, delay in arranging blood for hemorrhaging patients and delay in surgical intervention. Substandard care factors were present in majority of cases of maternal deaths. Improvement of maternity care services in Civil Hospital Karachi is needed on an urgent basis. (author)

OBJECTIVE To determine the outcome in birds undergoing inhalation anesthesia and identify patient or procedure variables associated with an increased likelihood of anesthesia-related death. DESIGN Retrospective case series. ANIMALS 352 birds that underwent inhalation anesthesia. PROCEDURES Medical records of birds that underwent inhalation anesthesia from January 1, 2004, through December 31, 2014, at a single veterinary referral hospital were reviewed. Data collected included date of visit, age, species, sex, type (pet, free ranging, or wild kept in captivity), body weight, body condition score, diagnosis, procedure, American Society of Anesthesiologists status, premedication used for anesthesia, drug for anesthetic induction, type of maintenance anesthesia, route and type of fluid administration, volumes of crystalloid and colloid fluids administered, intraoperative events, estimated blood loss, duration of anesthesia, surgery duration, recovery time, recovery notes, whether birds survived to hospital discharge, time of death, total cost of hospitalization, cost of anesthesia, and nadir and peak values for heart rate, end-tidal partial pressure of carbon dioxide, concentration of inhaled anesthetic, and body temperature. Comparisons were made between birds that did and did not survive to hospital discharge. RESULTS Of 352 birds, 303 (86%) were alive at hospital discharge, 12 (3.4%) died during anesthesia, 15 (4.3%) died in the intensive care unit after anesthesia, and 22 (6.3%) were euthanatized after anesthesia. Overall, none of the variables studied were associated with survival to hospital discharge versus not surviving to hospital discharge. CONCLUSIONS AND CLINICAL RELEVANCE Results confirmed previous findings that indicated birds have a high mortality rate during and after anesthesia, compared with mortality rates published for dogs and cats.

Referring to our experience with post-mortem computed tomography (CT), many hypothermic death cases presented a lack of increase in lung-field concentration, blood clotting in the heart, thoracic aorta or pulmonary artery, and urine retention in the bladder. Thus we evaluated the diagnostic performance of post-mortem CT on hypothermic death based on the above-mentioned three findings. Twenty-four hypothermic death subjects and 53 non-hypothermic death subjects were examined. Two radiologists assessed the presence or lack of an increase in lung-field concentration, blood clotting in the heart, thoracic aorta or pulmonary artery, and measured urine volume in the bladder. Pearson's chi-square test and Mann-Whitney U-test were used to assess the relationship between the three findings and hypothermic death. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of the diagnosis were also calculated. Lack of an increase in lung-field concentration and blood clotting in the heart, thoracic aorta or pulmonary artery were significantly associated with hypothermic death (p=0.0007, p<0.0001, respectively). The hypothermic death cases had significantly more urine in the bladder than the non-hypothermic death cases (p=0.0011). Regarding the diagnostic performance with all three findings, the sensitivity was 29.2% but the specificity was 100%. These three findings were more common in hypothermic death cases. Although the sensitivity was low, these findings will assist forensic physicians in diagnosing hypothermic death since the specificity was high. Copyright © 2012 Elsevier Ireland Ltd.

Full Text Available to analyse the impact of in-hospital care on severe maternal morbidity using WHO's near-miss approach in the low-resource, high mortality setting of Zanzibar's referral hospital.Mnazi Mmoja Hospital, a tertiary care facility, in Zanzibar, Tanzania.We identified all cases of morbidity and mortality in women admitted within 42 days after the end of pregnancy at Mnazi Mmoja Hospital in the period from April to October 2016. The severity of complications was classified using WHO's near-miss approach definitions: potentially life-threatening condition (PLTC, maternal near-miss (MNM or maternal death (MD. Quality of in-hospital care was assessed using the mortality index (MI defined as ratio between mortality and severe maternal outcome (SMO where SMO = MD + MNM, cause-specific case facility rates and comparison with predicted mortality based on the Maternal Severity Index model.5551 women were included. 569 (10.3% had a potentially life-threatening condition and 65 (1.2% a severe maternal outcome (SMO: 37 maternal near-miss cases and 28 maternal deaths. The mortality index was high at 0.43 and similar for women who developed a SMO within 12 hours of admission and women who developed a SMO after 12 hours. A standardized mortality ratio of 6.03 was found; six times higher than that expected in moderate maternal mortality settings given the same severity of cases. Obstetric haemorrhage was found to be the main cause of SMO. Ruptured uterus and admission to ICU had the highest case-fatality rates. Maternal death cases seemed to have received essential interventions less often.WHO's near-miss approach can be used in this setting. The high mortality index observed shows that in-hospital care is not preventing progression of disease adequately once a severe complication occurs. Almost one in two women experiencing life-threatening complications will die. This is six times higher than in moderate mortality settings.

2011-09-01

To examine the correlation between cell death and a common surrogate of death used in screening assays, we compared cell death responses to those obtained with the sulforhodamine B (SRB) cell protein-based "cytotoxicity" assay. With the SRB assay, the Hill equation was used to obtain an IC50 and final cell mass, or cell mass present at infinite agent concentrations, with eight adherent cell lines and four agents (32 agent/cell combinations). Cells were treated with high agent concentrations (well above the SRB IC50) and the death response determined as the time-dependent decrease in cells failing to bind both annexin V and vital fluorochromes by flow cytometry. Death kinetics were categorized as fast (5/32) (similar to the reference nonadherent Jurkat line), slow (17/32), or none (10/32), despite positive responses in the SRB assay in all cases. With slow cell death, a single exposure to a chemotherapeutic agent caused a slow, progressive increase in dead (necrotic) and dying (apoptotic) cells for at least 72 h. Cell death (defined by annexin and/or fluorochrome binding) did not correlate with the standard SRB "cytotoxicity" assay. With the slow cell death response, a single exposure to an agent caused a slow conversion from vital to apoptotic and necrotic cells over at least 72 h (the longest time point examined). Here, increasing the time of exposure to agent concentrations modestly above the SRB IC50 provides a method of maximizing cell kill. If tumors respond similarly, sustained low doses of chemotherapeutic agents, rather than a log-kill, maximum tolerated dose strategy may be an optimal strategy of maximizing tumor cell death.

2009-07-01

Full Text Available Abstract Background In sub-Saharan Africa, maternal and perinatal mortality and morbidity are major problems. Service availability and quality of care in health facilities are heterogeneous and most often inadequate. In resource-poor settings, the facility-based maternal death review or audit is one of the most promising strategies to improve health service performance. We aim to explore and describe health workers' perceptions of facility-based maternal death reviews and to identify barriers to and facilitators of the implementation of this approach in pilot health facilities of Senegal. Methods This study was conducted in five reference hospitals in Senegal with different characteristics. Data were collected from focus group discussions, participant observations of audit meetings, audit documents and interviews with the staff of the maternity unit. Data were analysed by means of both quantitative and qualitative approaches. Results Health professionals and service administrators were receptive and adhered relatively well to the process and the results of the audits, although some considered the situation destabilizing or even threatening. The main barriers to the implementation of maternal deaths reviews were: (1 bad quality of information in medical files; (2 non-participation of the head of department in the audit meetings; (3 lack of feedback to the staff who did not attend the audit meetings. The main facilitators were: (1 high level of professional qualifications or experience of the data collector; (2 involvement of the head of the maternity unit, acting as a moderator during the audit meetings; (3 participation of managers in the audit session to plan appropriate and realistic actions to prevent other maternal deaths. Conclusion The identification of the barriers to and the facilitators of the implementation of maternal death reviews is an essential step for the future adaptation of this method in countries with few resources.

Allers, Katharina; Hoffmann, Falk

2018-05-02

The proportion of deaths occurring in nursing homes is increasing and end of life hospitalizations in residents are common. This study aimed to obtain the time from nursing home admission to death and the frequency of hospitalizations prior to death among residents with and without dementia. This retrospective cohort study analyzed claims data of 127,227 nursing home residents aged 65 years and older newly admitted to a nursing home between 2010 and 2014. We analyzed hospitalizations during the last year of life and assessed mortality rates per 100 person-years. Factors potentially associated with time to death were analyzed in Cox proportional hazard models. The median time from nursing home admission to death was 777 and 635 days in residents with and without dementia, respectively. Being male, older age and a higher level of care decreased the survival time. Sex and age had a higher influence on survival time in residents with dementia, whereas level of care was found to have a higher influence in residents without dementia. Half of the residents of both groups were hospitalized during the last month and about 37% during the last week before death. Leading causes of hospitalizations were infections (with dementia: 20.6% vs. without dementia: 17.2%) and cardiovascular diseases (with dementia: 16.6% vs. without dementia: 19.0%). A high proportion of residents with and without dementia are hospitalized shortly before death. There should be an open debate about the appropriateness of hospitalizing nursing home residents especially those with dementia near death.

Hospitalized salmonellosis patients with concurrent chronic conditions may be at increased risk for adverse outcomes, increasing the costs associated with hospitalization. Identifying important modifiable risk factors for this predominantly foodborne illness may assist hospitals, physicians, and public health authorities to improve management of these patients. The objectives of this study were to (1) quantify the burden of salmonellosis hospitalizations in the United States, (2) describe hospitalization characteristics among salmonellosis patients with concurrent chronic conditions, and (3) examine the relationships between salmonellosis and comorbidities by four hospital-related outcomes. A retrospective analysis of salmonellosis discharges was conducted using the Agency for Healthcare Research and Quality's Nationwide Inpatient Sample for 2011. A supplemental trend analysis was performed for the period 2000-2011. Hospitalization characteristics were examined using multivariable regression modeling, with a focus on four outcome measures: in-hospital death, total amount billed by hospitals for services, length of stay, and disease severity. In 2011, there were 11,032 total salmonellosis diagnoses; 7496 were listed as the primary diagnosis, with 86 deaths (case-fatality rate = 1.2%). Multivariable regression analyses revealed a greater number of chronic conditions (≥4) among salmonellosis patients was associated with higher mean total amount billed by hospitals for services, longer length of stay, and greater disease severity (p ≤ 0.05). From 2000 to 2011, hospital discharges for salmonellosis increased by 27.2%, and the mean total amount billed by hospitals increased nearly threefold: $9,777 (2000) to $29,690 (2011). Observed increases in hospitalizations indicate the burden of salmonellosis remains substantial in the United States. The positive association between increased number of chronic conditions and the four hospital-related outcomes affirms

2016-08-19

In 2013, more than 57,000 persons died in the United States as a result of violence-related injuries. This report summarizes data from CDC's National Violent Death Reporting System (NVDRS) regarding violent deaths from 17 U.S. states for 2013. Results are reported by sex, age group, race/ethnicity, marital status, location of injury, method of injury, circumstances of injury, and other selected characteristics. 2013. NVDRS collects data from participating states regarding violent deaths obtained from death certificates, coroner/medical examiner reports, law enforcement reports, and secondary sources (e.g., child fatality review team data, supplemental homicide reports, hospital data, and crime laboratory data). This report includes data from 17 states that collected statewide data for 2013 (Alaska, Colorado, Georgia, Kentucky, Maryland, Massachusetts, North Carolina, New Jersey, New Mexico, Ohio, Oklahoma, Oregon, Rhode Island, South Carolina, Utah, Virginia, and Wisconsin). NVDRS collates documents for each death and links deaths that are related (e.g., multiple homicides, a homicide followed by a suicide, or multiple suicides) from a single incident. For 2013, a total of 18,765 fatal incidents involving 19,251 deaths were captured by NVDRS in the 17 states included in this report. The majority (66.2%) of deaths were suicides, followed by homicides (23.2%), deaths of undetermined intent (8.8%), deaths involving legal intervention (1.2%) (i.e., deaths caused by law enforcement and other persons with legal authority to use deadly force, excluding legal executions), and unintentional firearm deaths (Revision [ICD-10] and does not denote the lawfulness or legality of the circumstances surrounding a death caused by law enforcement.) Suicides occurred at higher rates among males, non-Hispanic whites, American Indian/Alaska Natives, persons aged 45-64 years, and males aged ≥75 years. Suicides were preceded primarily by a mental health, intimate partner, or physical

Air quality and acute deaths in California, 2000-2012.

Many studies have shown an association between air quality and acute deaths, and such associations are widely interpreted as causal. Several factors call causation and even association into question, for example multiple testing and multiple modeling, publication bias and confirmation bias. Many published studies are difficult or impossible to reproduce because of lack of access to confidential data sources. Here we make publically available a dataset containing daily air quality levels, PM 2.5 and ozone, daily temperature levels, minimum and maximum and daily maximum relative humidity levels for the eight most populous California air basins, thirteen years, >2M deaths, over 37,000 exposure days. The data are analyzed using standard time series analysis, and a sensitivity analysis is computed varying model parameters, locations and years. Our analysis finds little evidence for association between air quality and acute deaths. These results are consistent with those for the widely cited NMMAPS dataset when the latter are restricted to California. The daily death variability was mostly explained by time of year or weather variables; Neither PM 2.5 nor ozone added appreciably to the prediction of daily deaths. These results call into question the widespread belief that association between air quality and acute deaths is causal/near-universal. Copyright © 2017 Elsevier Inc. All rights reserved.

There were 10 women and 21 men (aged 4 months to 60 years). In women, pregnancy was present in 40% of cases. In men, chronic renal failure (CRF) (38%) and AIDS (19%) were the pathologic conditions most frequently observed. Variation in distribution of cases throughout 18 years was not observed (p > 0.05). Mortality due to CM was 0.67% and variation in number of deaths was not found. In this endemic area, CM must be included in differential diagnosis of patients with risk factors such as pregnancy, CRF, and AIDS, especially if associated with pneumonia with miliary pattern or septicemia with splenomegaly.

Full Text Available Acute kidney injury (AKI is a common reason for hospital admission and complication of many inpatient procedures. The temporal incidence of AKI and the association of AKI admissions with in-hospital mortality are a growing problem in the world today. In this review, we discuss the epidemiology of AKI and its association with in-hospital mortality in the United States. AKI has been growing at a rate of 14% per year since 2001. However, the in-hospital mortality associated with AKI has been on the decline starting with 21.9% in 2001 to 9.1 in 2011, even though the number of AKI-related in-hospital deaths increased almost twofold from 147,943 to 285,768 deaths. We discuss the importance of the 71% reduction in AKI-related mortality among hospitalized patients in the United States and draw on the discussion of whether or not this is a phenomenon of hospital billing (coding or improvements to the management of AKI.

Routine blood tests are an integral part of clinical medicine and in interpreting blood test results clinicians have two broad options. (1) Dichotomise the blood tests into normal/abnormal or (2) use the actual values and overlook the reference values. We refer to these as the "binary" and the "non-binary" strategy respectively. We investigate which strategy is better at predicting the risk of death in hospital based on seven routinely undertaken blood tests (albumin, creatinine, haemoglobin, potassium, sodium, urea, and white blood cell count) using tree models to implement the two strategies. A retrospective database study of emergency admissions to an acute hospital during April 2009 to March 2010, involving 10,050 emergency admissions with routine blood tests undertaken within 24 hours of admission. We compared the area under the Receiver Operating Characteristics (ROC) curve for predicting in-hospital mortality using the binary and non-binary strategy. The mortality rate was 6.98% (701/10050). The mean predicted risk of death in those who died was significantly (p-value non-binary strategy (risk = 0.222 95%CI: 0.194 to 0.251), representing a risk difference of 28.74 deaths in the deceased patients (n = 701). The binary strategy had a significantly (p-value non-binary strategy (0.853 95% CI: 0.840 to 0.867). Similar results were obtained using data from another hospital. Dichotomising routine blood test results is less accurate in predicting in-hospital mortality than using actual test values because it underestimates the risk of death in patients who died. Further research into the use of actual blood test values in clinical decision making is required especially as the infrastructure to implement this potentially promising strategy already exists in most hospitals.

Coronary artery bypass grafting currently is the best treatment for dialytic patients with multivessel coronary disease, but hospital morbidity and mortality related to procedure is still high. Evaluate results and in-hospital outcomes of coronary artery bypass grafting in dialytic patients. Retrospective unicentric study including 50 consecutive and not selected dialytic patients, who underwent coronary artery bypass grafting in a tertiary university hospital from 2007 to 2012. High prevalence of cardiovascular risk factors was observed (100% hypertensive, 68% diabetic and 40% dyslipidemic). There was no intra-operative death and 60% of the procedures were performed off-pump. There were seven (14%) in-hospital deaths. Postoperative infection, previous heart failure, cardiopulmonary bypass, abnormal ventricular function and surgical re-exploration were associated with increased mortality. Coronary artery bypass grafting is feasible to dialytic patients although high in-hospital morbidity and mortality.

The number of reported pregnancy-related deaths in the United States steadily increased from 7.2 deaths per 100,000 live births in 1987 to a high of 17.8 deaths per 100,000 live births in 2009. Compared to Caucasian women, African American women were nearly 4 times as likely to die from childbirth. To better understand the reason for this trend, we conducted a case-control study at University of Alabama at Birmingham (UAB) Hospital. Our primary study hypothesis was that women who died at UAB were more likely to be African American than women in a control group who delivered an infant at UAB and did not die. We expected to find a difference in race proportions and other patient characteristics that would further help to elucidate the cause of a racial disparity in maternal deaths. We reviewed all maternal deaths (cases) at UAB Hospital from January 1990 through December 2010 identified based on electronic uniform billing data and ICD-9 codes. Each maternal death was matched 2:1 with women who delivered at a time that most closely coincided with the time of the maternal death in 2-step selection process (electronic identification and manual confirmation). Maternal variables obtained were comorbidities, duration of hospital stay, cause of death, race, distance from home to hospital, income, prenatal care, body mass index, parity, insurance type, mode of delivery, and marital status. The strength of univariate associations of maternal variables and case/control status was calculated. The association of case/control status and race was also examined after controlling for residential distance from the hospital. There was insufficient evidence to suggest racial disparity in maternal death. The proportion of African American women was 57% (42 of 77) in the maternal death group and 61% (94 of 154) in the control group (P = 0.23). The univariate odds ratio for maternal death for African American to Caucasian race was 0.66 (95% confidence interval [CI], 0.37-1.19); the

To clarify the necessity for and problems related to autopsy for determining the cause of maternal death in Japan. Women who died during pregnancy or within a year after delivery were analyzed by the Maternal Death Exploratory Committee between 2012 and 2015 in Japan. Maternal deaths were analyzed to verify the requirement of autopsy in cases in which autopsy was performed and the need for autopsy in cases in which it was not performed. Among the 49 cases performed autopsy, the final diagnosis was compatible with the clinical course in 24 cases, while the autopsy diagnosis was incompatible with the clinical course in 13 cases. In two cases, the final diagnosis was based on the clinical course, but an autopsy could exclude other possible causes. In three cases, no exact cause of maternal death was identified after autopsy. On the other hand, in cases without an autopsy, the final diagnosis was made using ante-mortem operating findings and surgical specimens in twenty-one cases. Though, thirty-one cases were estimated diagnosis based on post-mortem imaging or ante-mortem examinations, the exact original cause of death was not determined in 25 cases, and the cause of death could not be identified in eight cases without autopsy. Because in most cases the autopsy provides an exact cause of death, the necessity of autopsies should be more widely accepted in Japan.

Neonatal near miss cases occur more often than neonatal deaths and could enable a more comprehensive analysis of risk factors, short-term outcomes and prognostic factors in neonates born to mothers with severe obstetric complications. The objective was to assess the incidence, presentation and perinatal outcomes of severe obstetric morbidity in two referral hospitals in Central Uganda. A prospective cohort study was conducted between March 1, 2013 and February 28, 2014, in which all newborns from cases of severe pregnancy and childbirth complications were eligible for inclusion. The obstetric conditions included obstetric haemorrhage, hypertensive disorders, obstructed labour, chorioamnionitis and pregnancy-specific complications such as malaria, anemia and premature rupture of membranes. Still births, neonatal deaths and neonatal near miss cases (defined using criteria that employed clinical features, presence of organ-system dysfunction and management provided to the newborns were compiled). Stratified and multivariate logistic regression analysis was conducted to identify risk factors for perinatal death. Of the 3100 mothers, 192 (6.2%) had abortion complications. Of the remainder, there were 2142 (73.1%) deliveries, from whom the fetal outcomes were 257 (12.0%) still births, 369 (17.2%) neonatal deaths, 786 (36.7%) neonatal near misses and 730 (34.1%) were newborns with no or minimal life threatening complications. Of the 235 babies admitted to the neonatal intensive care unit (NICU), the main reasons for admission were prematurity for 64 (26.8%), birth asphyxia for 59 (23.7%), and grunting respiration for 26 (11.1%). Of the 235 babies, 38 (16.2%) died in the neonatal period, and of these, 16 died in the first 24 hours after admission. Ruptured uterus caused the highest case-specific mortality of 76.8%, and led to 16.9% of all newborn deaths. Across the four groups, there were significant differences in mean birth weight, p = 0.003. Antepartum hemorrhage

Full Text Available Objective: Systemic sclerosis (SSc is an uncommon non-hereditary sporadic disease that increases the risk of premature death, especially in diffuse type. We determined the prevalence of SSc in the last 13 years in our rheumatologic hospitals as a referral center for southern Iranian patients, the causes of hospitalization, the average length of stay (LOS, the mortality rate, and the reason for their mortality. Material and methods : A cross-sectional study was performed in Shiraz University of Medical Sciences, Iran. The studied population included all patients diagnosed with systemic sclerosis. We calculated the hospitalization rates, in-hospital mortality rates, and mean LOS. Results: There were 446 admissions by 181 patients with SSc. The female to male ratio was about 10.7 : 1. The overall mean LOS was 5.95 days. Digital ulcer and interstitial lung disease (ILD were the most common causes of hospitalizations among the SSc-related events. For those with a non-SSc-related condition, infection was the most prevalent event. Most of the deaths were due to ILD and pulmonary artery hypertension(PAH, and the overall in-hospital mortality rate was 16.5%. Conclusions : Women with SSc had higher rates of hospitalization but lower in-hospital mortality than men.There were some differences between our study and other similar studies in the causes of hospitalization and in-hospital death among SSc patients, especially the lower age of death. The patients with digital ulcers and those with intestinal lung disease or pulmonary hipertension were most commonly admitted to the hospital in our study group. Probably, increasing the skin care of these patients and asking other specialty groups to cooperate will decrease the high rate of hospitalizations in our population.
