    Studies on inflammatory bowel disease (IBD) have reported suboptimal approaches to patient care. In the United States, the findings have motivated leading gastroenterology organizations to call for initiatives that support clinicians in aligning their practices with quality measures for IBD and priorities of the National Quality Strategy (NQS). We designed and implemented a quality improvement (QI) education program on ulcerative colitis in which patient charts were audited for 30 gastroenterologists before (n = 300 charts) and after (n = 290 charts) they participated in QI-focused educational activities. Charts were audited for nine measures, selected for their alignment with four NQS priorities: making care safer, ensuring patient engagement, promoting communication, and promoting effective treatment practices. Four of the measures, including guideline-directed vaccinations and assessments of disease type and activity, were part of the CMS Physician Quality Reporting System (PQRS). The other five measures involved counseling patients on various topics in ulcerative colitis management, documentation of side effects, assessment of adherence status, and simplification of dosing. The gastroenterologists also completed baseline and post-education surveys designed to assess qualitative outcomes. One of the educational interventions was a private audit feedback session conducted for each gastroenterologist. The sessions were designed to support participants in identifying measures reflecting suboptimal care quality and developing action plans for improvement. In continuous improvement cycles, follow-up interventions included QI tools and educational monographs. Across the nine chart variables, post-education improvements ranged from 0% to 48%, with a mean improvement of 15.9%. Survey findings revealed improvements in self-reported understanding of quality measures and intentions to apply them to practice, and lower rates of perceived significant barriers to high-quality

    To evaluate the impact of care at high-performing hospitals on the National Quality Forum (NQF) colon cancer metrics. The NQF endorses evaluating ≥12 lymph nodes (LNs), adjuvant chemotherapy (AC) for stage III patients, and AC within 4 months of diagnosis as colon cancer quality indicators. Data on hospital-level metric performance and the association with survival are unclear. Retrospective cohort study of 218,186 patients with resected stage I to III colon cancer in the National Cancer Data Base (2004-2012). High-performing hospitals (>75% achievement) were identified by the proportion of patients achieving each measure. The association between hospital performance and survival was evaluated using Cox shared frailty modeling. Only hospital LN performance improved (15.8% in 2004 vs 80.7% in 2012; trend test, P fashion [0 metrics, reference; 1, hazard ratio (HR) 0.96 (0.89-1.03); 2, HR 0.92 (0.87-0.98); 3, HR 0.85 (0.80-0.90); 2 vs 1, HR 0.96 (0.91-1.01); 3 vs 1, HR 0.89 (0.84-0.93); 3 vs 2, HR 0.95 (0.89-0.95)]. Performance on metrics in combination was associated with lower risk of death [LN + AC, HR 0.86 (0.78-0.95); AC + timely AC, HR 0.92 (0.87-0.98); LN + AC + timely AC, HR 0.85 (0.80-0.90)], whereas individual measures were not [LN, HR 0.95 (0.88-1.04); AC, HR 0.95 (0.87-1.05)]. Less than half of hospitals perform well on these NQF colon cancer metrics concurrently, and high performance on individual measures is not associated with improved survival. Quality improvement efforts should shift focus from individual measures to defining composite measures encompassing the overall multimodal care pathway and capturing successful transitions from one care modality to another.

    In recent years researchers have reported deficits in the quality of care provided to patients with rheumatoid arthritis (RA), including low rates of performance on quality measures. We sought to determine the influence of a quality improvement (QI) continuing education program on rheumatologists' performance on national quality measures for RA, along with other measures aligned with National Quality Strategy priorities. Performance was assessed through baseline and post-education chart audits. Twenty community-based rheumatologists across the United States were recruited to participate in the QI education program and chart audits. Charts were retrospectively audited before (n = 160 charts) and after (n = 160 charts) the rheumatologists participated in a series of accredited QI-focused educational activities that included private audit feedback, small-group webinars, and online- and mobile-accessible print and video activities. The charts were audited for patient demographics and the rheumatologists' documented performance on the 6 quality measures for RA included in the Physician Quality Reporting System (PQRS). In addition, charts were abstracted for documentation of patient counseling about medication benefits/risks and adherence, lifestyle modifications, and quality of life; assessment of RA medication side effects; and assessment of RA medication adherence. Mean rates of documented performance on 4 of the 6 PQRS measures for RA were significantly higher in the post-education versus baseline charts (absolute increases ranged from 9 to 24% of patient charts). In addition, after the intervention, significantly higher mean rates were observed for patient counseling about medications and quality of life, and for assessments of medication side effects and adherence (absolute increases ranged from 9 to 40% of patient charts). This pragmatic study provides preliminary evidence for the positive influence of QI-focused education in helping rheumatologists improve

    The National Control Center for Medical Devices (CCEEM) is a regulatory agency, belongs to the Cuban Ministry of Public Heath. It works to guarantee the safety and effectiveness of medical devices used into the National Health System (NHS) and the patient, and user protection. Quality Control assures that particular aspect will be satisfied, so since several years ago a national programme for the quality control of nuclear medicine instruments has been organized and established. A service was created in order to control periodically the state of the instrumentation in all the nuclear medicine departments, it is making annual quality control audits and participating in comparisons exercises organises by CCEEM. 3 comparisons exercises with CENTIS and services of NHS were made and eleven nuclear medicine departments were audited in order to perform a practical evaluation of this service, giving the two new regulations and general instructions to dose administration. The objects of the present work is shows, by those results, how does a quality audits work in National Harmonization of Activity Measurement over Nuclear Medicine Measurement in Cuba

  10. Measurement quality assurance

    The quality of a radiation protection program can be no better than the quality of the measurements made to support it. In many cases, that quality is unknown and is merely implied on the basis of a calibration of a measuring instrument. If that calibration is inappropriate or is performed improperly, the measurement result will be inaccurate and misleading. Assurance of measurement quality can be achieved if appropriate procedures are followed, including periodic quality control actions that demonstrate adequate performance. Several national measurement quality assurance (MQA) programs are operational or under development in specific areas. They employ secondary standards laboratories that provide a high-quality link between the National Bureau of Standards and measurements made at the field use level. The procedures followed by these secondary laboratories to achieve MQA will be described, as well as plans for similar future programs. A growing general national interest in quality assurance, combined with strong specific motivations for MQA in the area of ionizing radiation, will provide continued demand for appropriate national programs. Such programs must, however, employ procedures that are cost effective and must be developed with participation by all affected parties

  11. Development, enhancement, and evaluation of aircraft measurement techniques for national ambient air quality standard criteria pollutants

    Brent, Lacey Cluff

    The atmospheric contaminants most harmful to human health are designated Criteria Pollutants. To help Maryland attain the national ambient air quality standards (NAAQS) for Criteria Pollutants, and to improve our fundamental understanding of atmospheric chemistry, I conducted aircraft measurements in the Regional Atmospheric Measurement Modeling Prediction Program (RAMMPP). These data are used to evaluate model simulations and satellite observations. I developed techniques for improving airborne observation of two NAAQS pollutants, particulate matter (PM) and nitrogen dioxide (NO2). While structure and composition of organic aerosol are important for understanding PM formation, the molecular speciation of organic ambient aerosol remains largely unknown. The spatial distribution of reactive nitrogen is likewise poorly constrained. To examine water-soluble organic aerosol (WSOA) during an air pollution episode, I designed and implemented a shrouded aerosol inlet system to collect PM onto quartz fiber filters from a Cessna 402 research aircraft. Inlet evaluation conducted during a side-by-side flight with the NASA P3 demonstrated agreement to within 30%. An ion chromatographic mass spectrometric method developed using the NIST Standard Reference Material (SRM) 1649b Urban Dust, as a surrogate material resulted in acidic class separation and resolution of at least 34 organic acids; detection limits approach pg/g concentrations. Analysis of aircraft filter samples resulted in detection of 8 inorganic species and 16 organic acids of which 12 were quantified. Aged, re-circulated metropolitan air showed a greater number of dicarboxylic acids compared to air recently transported from the west. While the NAAQS for NO2 is rarely exceeded, it is a precursor molecule for ozone, America's most recalcitrant pollutant. Using cavity ringdown spectroscopy employing a light emitting diode (LED), I measured vertical profiles of NO2 (surface to 2.5 km) west (upwind) of the Baltimore

    Water-quality activities and water-level measurements by the personnel of the U.S. Geological Survey (USGS) Idaho National Laboratory (INL) Project Office coincide with the USGS mission of appraising the quantity and quality of the Nation’s water resources. The activities are carried out in cooperation with the U.S. Department of Energy (DOE) Idaho Operations Office. Results of the water-quality and hydraulic head investigations are presented in various USGS publications or in refereed scientific journals and the data are stored in the National Water Information System (NWIS) database. The results of the studies are used by researchers, regulatory and managerial agencies, and interested civic groups. In the broadest sense, quality assurance refers to doing the job right the first time. It includes the functions of planning for products, review and acceptance of the products, and an audit designed to evaluate the system that produces the products. Quality control and quality assurance differ in that quality control ensures that things are done correctly given the “state-of-the-art” technology, and quality assurance ensures that quality control is maintained within specified limits.

    Suspended-sediment transport is a critical element governing the geomorphology of tidal marshes. Marshes rely on both organic material and inorganic sediment deposition to maintain their elevation relative to sea level. In wetlands near the Blackwater National Wildlife Refuge, Maryland, portions of the salt marsh have been subsiding relative to sea level since the early 20th century. Other portions of the marsh have been successful at maintaining elevation. The U.S. Geological Survey performed observational deployments to measure suspended-sediment concentration in the tidal channels in order to understand the magnitude of suspended-sediment concentrations, the sediment-transport mechanisms, and differences between two marsh areas, one that subsided and one that maintained elevation. We deployed optical turbidity sensors and acoustic velocity meters at multiple sites over two periods in 2011. This report presents the time-series of oceanographic data collected during those field studies, including velocity, depth, turbidity, salinity, water temperature, and pH.

    Perioperative hypothermia may increase the incidences of wound infection, blood loss, transfusion, and cardiac morbidity. US national quality programs for perioperative normothermia specify the presence of at least 1 "body temperature" ≥35.5°C during the interval from 30 minutes before to 15 minutes after the anesthesia end time. Using data from 4 academic hospitals, we evaluated timing and measurement considerations relevant to the current requirements to guide hospitals wishing to report perioperative temperature measures using electronic data sources. Anesthesia information management system databases from 4 hospitals were queried to obtain intraoperative temperatures and intervals to the anesthesia end time from discontinuation of temperature monitoring, end of surgery, and extubation. Inclusion criteria included age >16 years, use of a tracheal tube or supraglottic airway, and case duration ≥60 minutes. The end-of-case temperature was determined as the maximum intraoperative temperature recorded within 30 minutes before the anesthesia end time (ie, the temperature that would be used for reporting purposes). The fractions of cases with intervals >30 minutes between the last intraoperative temperature and the anesthesia end time were determined. Among the hospitals, averages (binned by quarters) of 34.5% to 59.5% of cases had intraoperative temperature monitoring discontinued >30 minutes before the anesthesia end time. Even if temperature measurement had been continued until extubation, averages of 5.9% to 20.8% of cases would have exceeded the allowed 30-minute window. Averages of 8.9% to 21.3% of cases had end-of-case intraoperative temperatures <35.5°C (ie, a quality measure failure). Because of timing considerations, a substantial fraction of cases would have been ineligible to use the end-of-case intraoperative temperature for national quality program reporting. Thus, retrieval of postanesthesia care unit temperatures would have been necessary. A

    Objectives We examine whether multiple health-related quality of life (HRQoL) measures are stratified by socioeconomic status (SES) and age in the United States. Methods Data are from the 2005/2006 National Health Measurement Study, a telephone survey of a nationally representative sample of U.S. adults. We plot mean HRQoL scores by SES within age groups. Regression analyses test whether education, income, and assets each have independent associations with three “preference-based” HRQoL measures and self-rated health (SRH). We test whether these associations vary by age. Results There are SES disparities in HRQoL and SRH among adults in the United States at all age groups. Income differentials in HRQoL are strong across current adult age cohorts, except the 75–89 age cohort. Education and assets have statistically significant but weaker associations with HRQoL. All three SES measures are associated with SRH (net of each other) at every age group. Those in the lowest income and education groups in the 35–44 age cohort have worse HRQoL and SRH than those in higher SES groups in the 65+ age cohort. Discussion Significant improvements in HRQoL at the population level will only be possible if we improve the HRQoL of people at the lowest end of the socioeconomic distribution. PMID:19307286

    Bias in HbA1c measurement could give a wrong impression of the standard of care when benchmarking diabetes care. The aim of this study was to evaluate how measurement bias in HbA1c results may influence the benchmarking process performed by a national diabetes register. Using data from 2012 from the Norwegian Diabetes Register for Adults, we included HbA1c results from 3584 patients with type 1 diabetes attending 13 hospital clinics, and 1366 patients with type 2 diabetes attending 18 GP offices. Correction factors for HbA1c were obtained by comparing the results of the hospital laboratories'/GP offices' external quality assurance scheme with the target value from a reference method. Compared with the uncorrected yearly median HbA1c values for hospital clinics and GP offices, EQA corrected HbA1c values were within ±0.2% (2 mmol/mol) for all but one hospital clinic whose value was reduced by 0.4% (4 mmol/mol). Three hospital clinics reduced the proportion of patients with poor glycemic control, one by 9% and two by 4%. For most participants in our study, correcting for measurement bias had little effect on the yearly median HbA1c value or the percentage of patients achieving glycemic goals. However, at three hospital clinics correcting for measurement bias had an important effect on HbA1c benchmarking results especially with regard to percentages of patients achieving glycemic targets. The analytical quality of HbA1c should be taken into account when comparing benchmarking results.

    This study aimed to evaluate diabetes quality measurement efforts, assess their strengths and areas for improvement, and identify gaps not adequately addressed by these measures. We conducted an environmental scan of diabetes quality measures, focusing on metrics included in the National Quality Measures Clearinghouse or promulgated by leading measurement organizations. Key informant interviews were also completed with thought leaders who develop, promote, and use quality measures. The environmental scan identified 146 distinct measures spanning 31 clinical processes or outcomes. This suggests a measurement system that is both redundant and inconsistent, with many different measures assessing the same clinical indicators. Interviewees believe that current diabetes measurement efforts are excessively broad and complex and expressed a need for better harmonization of these measures. Several gaps were also found, including a lack of measures focusing on population health, structural elements of health care, and prevention of diabetes.

    To monitor quality of life (QOL) for patients with cancer in a large population-based survey, we developed a short QOL and quality-of-care (QOC) questionnaire. To determine the validity and reliability of this new questionnaire for evaluating QOL in patients with cancer. Outpatients and inpatients at National Cancer Center Hospital East were administered a questionnaire, including the following items-the short QOL and QOC questionnaire (physical distress, pain, emotional distress, walk burden, and need for help with self-care; perceived general health status; and satisfaction with medical care and treatment by doctor, communication with doctor, support by health-care staff other than doctor, care for physical symptoms such as pain, and psychological care), the Functional Assessment of Cancer Therapy-General (FACT-G), the Cancer Care Evaluation Scale (CCES) for patients, and demographic and medical data. We then readministered the short QOL and QOC questionnaire. In total, 329 outpatients and 239 inpatients completed the survey (response rates: 80% and 90%, respectively). Total Cronbach α for the short QOL and QOC questionnaire was 0.83 for outpatients and 0.82 for inpatients. Items of the questionnaire correlated with cancer-specific measurements, FACT-G, and CCES. Intraclass correlation coefficients for all items of the questionnaire were 0.79 and 0.89 in each setting. Items of QOL and QOC did not correlate with each other. The validity and reliability of the short QOL and QOC questionnaire appear sufficient. This questionnaire enables continuous monitoring of patient QOL in large population-based surveys.

    In recent years, there has been increased interest in measuring the climate for infection prevention; however, reliable and valid instruments are lacking. This study tested the psychometric properties of the Leading a Culture of Quality for Infection Prevention (LCQ-IP) instrument measuring the infection prevention climate in a sample of 972 infection preventionists from acute care hospitals. An exploratory principal component analysis showed that the instrument had structural validity and captured 4 factors related to the climate for infection prevention: Psychological Safety, Prioritization of Quality, Supportive Work Environment, and Improvement Orientation. LCQ-IP exhibited excellent internal consistency, with a Cronbach α of .926. Criterion validity was supported with overall LCQ-IP scores, increasing with the number of evidence-based prevention policies in place (P = .047). This psychometrically sound instrument may be helpful to researchers and providers in assessing climate for quality related to infection prevention. © The Author(s) 2015.

    Purpose In recognition of the importance of performance measurement and MCH epidemiology leadership to quality improvement (QI) efforts, a plenary session dedicated to this topic was presented at the 2014 CityMatCH Leadership and MCH Epidemiology Conference. This paper summarizes the session and provides two applications of performance measurement to QI in MCH. Description Performance measures addressing processes of care are ubiquitous in the current health system landscape and the MCH community is increasingly applying QI processes, such as Plan-Do-Study-Act (PDSA) cycles, to improve the effectiveness and efficiency of systems impacting MCH populations. QI is maximally effective when well-defined performance measures are used to monitor change. Assessment MCH epidemiologists provide leadership to QI initiatives by identifying population-based outcomes that would benefit from QI, defining and implementing performance measures, assessing and improving data quality and timeliness, reporting variability in measures throughout PDSA cycles, evaluating QI initiative impact, and translating findings to stakeholders. MCH epidemiologists can also ensure that QI initiatives are aligned with MCH priorities at the local, state and federal levels. Two examples of this work, one highlighting use of a contraceptive service performance measure and another describing QI for peripartum hemorrhage prevention, demonstrate MCH epidemiologists' contributions throughout. Challenges remain in applying QI to complex community and systems-level interventions, including those aimed at improving access to quality care. Conclusion MCH epidemiologists provide leadership to QI initiatives by ensuring they are data-informed and supportive of a common MCH agenda, thereby optimizing the potential to improve MCH outcomes.

The SEP-1 performance measure requires, among other critical interventions, timely administration of antibiotics to patients with sepsis or septic shock. The multistakeholder workgroup recognizes the need for SEP-1 but strongly believes that multiple antibiotics listed in the antibiotic tables for SEP-1 are not appropriate and the use of these antibiotics, as called for in the SEP-1 measure, is not in alignment with prudent antimicrobial stewardship. To promote the appropriate use of antimicrobials and combat antimicrobial resistance, the workgroup provides recommendations for appropriate antibiotics for the treatment of sepsis. © The Author 2017.

    Morbidity and mortality conferences have played a traditional role in tracking complications. Recently, the American College of Surgeons National Surgical Quality Improvement Program Pediatrics (ACS NSQIP-P) has gained popularity as a risk-adjusted means of addressing quality assurance. The purpose of this article is to report an analysis of the two methodologies used within pediatric plastic surgery to determine the best way to manage quality. ACS NSQIP-P and morbidity and mortality data were extracted for 2012 and 2013 at a quaternary care institution. Overall complication rates were compared statistically, segregated by type and severity, followed by a subset comparison of ACS NSQIP-P-eligible cases only. Concordance and discordance rates between the two methodologies were determined. One thousand two hundred sixty-one operations were performed in the study period. Only 51.4 percent of cases were ACS NSQIP-P eligible. The overall complication rates of ACS NSQIP-P (6.62 percent) and morbidity and mortality conferences (6.11 percent) were similar (p = 0.662). Comparing for only ACS NSQIP-P-eligible cases also yielded a similar rate (6.62 percent versus 5.71 percent; p = 0.503). Although different complications are tracked, the concordance rate for morbidity and mortality and ACS NSQIP-P was 35.1 percent and 32.5 percent, respectively. The ACS NSQIP-P database is able to accurately track complication rates similarly to morbidity and mortality conferences, although it samples only half of all procedures. Although both systems offer value, limitations exist, such as differences in definitions and purpose. Because of the rigor of the ACS NSQIP-P, we recommend that it be expanded to include currently excluded cases and an extension of the study interval.

    The Italian Air Quality legislation underwent sweeping changes with the implementation of the 1996 European Air Quality Framework Directive when the Italian administrative Regions were entrusted with air quality management tasks. The most recent Regional Air Quality Management Plans (AQMPs) highlighted the importance of Non-Technical Measures (NTMs), in addition to Technical Measures (TMs), in meeting environmental targets. The aim of the present work is to compile a list of all the TMs and NTMs taken into account in the Italian Regional AQMPs and to give in the target year, 2010, an estimation of SO 2, NO x and PM 10 emission reductions, of PM 10 concentration and of the health impact of PM 2.5 concentrations in terms of Life Expectancy Reduction. In order to do that, RAINS-Italy, as part of the National Integrated Modeling system for International Negotiation on atmospheric pollution (MINNI), has been applied. The management of TMs and NTMs inside RAINS have often obliged both the introduction of exogenous driving force scenarios and the control strategy modification. This has inspired a revision of the many NTM definitions and a clear choice of the definition adopted. It was finally highlighted that only few TMs and NTMs implemented in the AQMPs represent effective measures in reaching the environmental targets.

    Suspended-sediment transport is a critical element controlling the geomorphology of tidal wetland complexes. Wetlands rely on organic material and inorganic sediment deposition to maintain their elevation relative to sea level. The U.S. Geological Survey performed observational deployments to measure suspended-sediment concentration and water flow rates in the tidal channels of the wetlands in the Rachel Carson National Wildlife Refuge in Wells, Maine. The objective was to characterize the sediment-transport mechanisms that contribute to the net sediment budget of the wetland complex. We deployed a meteorological tower, optical turbidity sensors, and acoustic velocity meters at sites on Stephens Brook and the Ogunquit River between March 27 and December 9, 2013. This report presents the time-series oceanographic and atmospheric data collected during those field studies. The oceanographic parameters include water velocity, depth, turbidity, salinity, temperature, and pH. The atmospheric parameters include wind direction, speed, and gust; air temperature; air pressure; relative humidity; short wave radiation; and photosynthetically active radiation.

    2010-02-01

    Full Text Available Happiness is rising on the political agenda and this calls for measures of how well nations perform in creating great happiness for a great number, analogous to measures of success in creating wealth, such as GDP. Happiness is defined as subjective enjoyment of one’s life as-a-whole and this can be measured using self-reports. Question on happiness are currently used in large scale surveys of the general population in nations. As a result we have now comparable data on happiness in 144 contemporary nations and time-series of 25 years and longer on 11 developed nations. These data can be aggregated in different ways: If the aim is simply greater happiness for a greater number of citizens, Average happiness (AH is an appropriate measure. If the focus is on enduring happiness, it is better to combine average happiness with longevity in an index of Happy Life Years (HLY. If the aim is to reduce disparity among citizens a relevant indicator is the Inequality of Happiness (IH in the nations as measured with the standard deviation. Average and dispersion can also be combined in an index of Inequality-Adjusted Happiness (IAH. Comparison across nations shows sizable differences on all these measures of gross national happiness and these differences correspond with societal characteristics that can be influenced by policy makers, such as freedom and justice. Comparison over time shows major improvement during the last decade.

    Existing quality models focus on some specific diseases, clinics or clinical areas. Although they contain structure, process, or output type measures, there is no model which measures quality of health care processes comprehensively. In addition, due to the not measured overall process quality, hospitals cannot compare quality of processes internally and externally. To bring a solution to above problems, a new model is developed from software quality measures. We have adopted the ISO/IEC 9126 software quality standard for health care processes. Then, JCIAS (Joint Commission International Accreditation Standards for Hospitals) measurable elements were added to model scope for unifying functional requirements. Assessment (diagnosing) process measurement results are provided in this paper. After the application, it was concluded that the model determines weak and strong aspects of the processes, gives a more detailed picture for the process quality, and provides quantifiable information to hospitals to compare their processes with multiple organizations.

    This study aimed to develop and validate an instrument to measure patient perception of quality of nursing care and related hospital services in a tertiary care setting. We compiled an instrument with 72 items that patients may perceive as quality of nursing care and related hospital services, following an extensive literature search, discussions with patients and care pro-I viders and a brainstorming session with an expert panel. A cross-sectional study was conducted at the National Hospital of Sri Lanka. A sample (n = 120) of patients stayed in general surgical or medical units responded to the interviewer administered instrument upon discharge. Item analysis and principal component factor analysis were performed to assess validity, and internal consistency was calculated to measure reliability. Of the 72 items, 18 had greater than 20% of responses as 'not relevant'. A further 11 items were eliminated since item-total correlations were less than .2. Factor analysis was performed on remaining 43 items which resulted in 36 items classifying into eight factors accounting for 71% of the variation. Factor loadings in the final solution after Varimax rotation were interpersonal aspects (.68-.85), efficiency (.62-.79), competency (.66-.68), comfort (.60-.84), physical environment (.65-.82), cleanliness (.81-.85), personalized information (.76-.83), and general instructions (.61-.78). The instrument had high Internal consistency (Cronbach's alpha = .91). We developed a comprehensive, reliable and valid, 36-item instrument that may be used to measure patient perception of quality of nursing care in tertiary care settings.

    This paper presents one part of the activities deployed by the Laboratory for Environment and Personnel Dosimetry (LDPM) of IFIN-HH, namely the radiological monitoring of the environment within the Institute's area and its surrounding influence zone, according to the program approved by the National Regulatory Body for Nuclear Activities, CNCAN. The representative reports regard the radioactive content of soil, surface and underground water, cultivated and spontaneous vegetation, aerosols and atmospheric fallout, sediments. The common requirement is that the measured quantities be precise and the reported values be reliable and credible. This goal is achieved by maintaining a Quality System, verified within the obtaining and maintaining of the laboratory accreditation, according to the international standard ISO/IEC 17025:2005.The LDPM is accredited by the Romanian accreditation body, RENAR, member of the European Accreditation, EA and is designed by CNCAN as a notified testing laboratory. Many measurements were performed in collaboration with the Radionuclide Metrology Laboratory (RML) from IFIN-HH, RENAR accredited and CNCAN notified for calibration and for testing in the field of radioactivity measurement. This paper proposes a short presentation of the important aspects in our activity: i. description of equipment, samplingmethods, processing and measurement of environmental samples; ii. validation of equipment and methods by participation in international and national proficiency tests; iii. a five year follow chart, containing the results in measurement of samples; iv. a recent application, with a wide impact in Romanian mass media: the credible daily report on the possible influence of Fukushima accident over the Romanian environmental radioactivity.

    The U.S. Geological Survey (USGS) conducted the National Coal Quality Inventory (NaCQI) between 1999 and 2005 to address a need for quality information on coals that will be mined during the next 20-30 years. Collaboration between the USGS, State geological surveys, universities, coal burning utilities, and the coal mining industry plus funding support from the Electric Power Research Institute (EPRI) and the U.S. Department of Energy (DOE) permitted collection and submittal of coal samples for analysis. The chemical data (proximate and ultimate analyses; major, minor and trace element concentrations) for 729 samples of raw or prepared coal, coal associated shale, and coal combustion products (fly ash, hopper ash, bottom ash and gypsum) from nine coal producing States are included. In addition, the project identified a new coal reference analytical standard, to be designated CWE-1 (West Elk Mine, Gunnison County, Colorado) that is a high-volatile-B or high-volatile-A bituminous coal with low contents of ash yield and sulfur, and very low, but detectable contents of chlorine, mercury and other trace elements.

    2016-06-01

    In this descriptive multi-site study, we examined inter-rater agreement on 11 National Database of Nursing Quality Indicators(®) (NDNQI(®) ) pressure ulcer (PrU) risk and prevention measures. One hundred twenty raters at 36 hospitals captured data from 1,637 patient records. At each hospital, agreement between the most experienced rater and each other team rater was calculated for each measure. In the ratings studied, 528 patients were rated as "at risk" for PrU and, therefore, were included in calculations of agreement for the prevention measures. Prevalence-adjusted kappa (PAK) was used to interpret inter-rater agreement because prevalence of single responses was high. The PAK values for eight measures indicated "substantial" to "near perfect" agreement between most experienced and other team raters: Skin assessment on admission (.977, 95% CI [.966-.989]), PrU risk assessment on admission (.978, 95% CI [.964-.993]), Time since last risk assessment (.790, 95% CI [.729-.852]), Risk assessment method (.997, 95% CI [.991-1.0]), Risk status (.877, 95% CI [.838-.917]), Any prevention (.856, 95% CI [.76-.943]), Skin assessment (.956, 95% CI [.904-1.0]), and Pressure-redistribution surface use (.839, 95% CI [.763-.916]). For three intervention measures, PAK values fell below the recommended value of ≥.610: Routine repositioning (.577, 95% CI [.494-.661]), Nutritional support (.500, 95% CI [.418-.581]), and Moisture management (.556, 95% CI [.469-.643]). Areas of disagreement were identified. Findings provide support for the reliability of 8 of the 11 measures. Further clarification of data collection procedures is needed to improve reliability for the less reliable measures. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    The credibility of obtained results is ensured by the quality assurance and control. The main requisitions involved in the quality assurance of the laboratory according to the requirements of LVS EN ISO/IEC 17025:2005 are: 1) the use of calibrated equipment only; 2) the regular and long-time use of reference materials in the control of equipment; 3) the estimation of uncertainty sources and determination of uncertainties within the given interval of credibility; 4) the validation and verification. The very important requirement is regular participation in the interlaboratory intercomparison exercises that makes it possible to estimate and find possible error sources and carry out the corrective actions. The measurements of the radioactivity of Cs-137, Co-60, H-3, the natural radioactive nuclides as well as other radionuclides in different environmental (soil, precipitation, different types of water, needles, et al.) samples, and in various radioactive polluted objects are carried out in the Laboratory of Radiation physics. The quality assurance system was implemented in our laboratory in 2000. Since 1999 laboratory is regular participant in the interlaboratory intercomparison exercises, organized by the RISO National Laboratory (Denmark) and IAEA (Vienna). The paper shows the laboratory's system of quality assurance and its implementation. We have the internal quality audit program that takes into account the requirements of LVS EN ISO/IEC 17025: 2005, but the main attention is paid to the intercomparison of the results of analyses of laboratories, their evaluation and interpretation. Only credible and justified results can be the basis for further use in any field, thus making it possible to make legitimate decisions. (Authors)

    Kleinpell, Ruth; Kapu, April N

    2017-08-01

    Evaluating the impact of nurse practitioner (NP) practice has become a priority area of focus for demonstrating outcomes. A number of quality measures are available to enable practice-specific evaluation of NP roles and initiatives. This article reviews sources of quality measures that can be used to facilitate quantifying the outcomes of NP practice as part of an overall evaluation agenda. National resources and published literature on NP quality measures were reviewed. Various resources and toolkits exist to assist NPs in identifying outcomes of practice using quality measures. The need to demonstrate outcomes of NP practice remains an ongoing priority area regardless of the clinical practice setting. A variety of sources of quality measures exist that can be used to showcase the effect of NP care. The use of quality measures can be effectively integrated into evaluation of NP role and NP-directed initiatives to demonstrate impact, and enhance the conduct of an NP outcomes assessment. The use of organizational, NP-specific, and national-related quality measures can help to showcase how NP care improves the quality, safety, and costs of health care. ©2017 American Association of Nurse Practitioners.

    We document methods for the quantitative evaluation of systems that produce a scalar summary of a biometric sample's quality. We are motivated by a need to test claims that quality measures are predictive of matching performance. We regard a quality measurement algorithm as a black box that converts an input sample to an output scalar. We evaluate it by quantifying the association between those values and observed matching results. We advance detection error trade-off and error versus reject characteristics as metrics for the comparative evaluation of sample quality measurement algorithms. We proceed this with a definition of sample quality, a description of the operational use of quality measures. We emphasize the performance goal by including a procedure for annotating the samples of a reference corpus with quality values derived from empirical recognition scores.

    Background: Measuring the quality of health care is a fundamental step toward improving health care and is increasingly used in pay-for-performance initiatives and maintenance of certification requirements. Measure development to date has focused on primary care and common conditions such as diabetes; thus, the number of measures that apply to neurologic care is limited. The American Academy of Neurology (AAN) identified the need for neurologists to develop measures of neurologic care and to establish a process to accomplish this. Objective: To adapt and test the feasibility of a process for independent development by the AAN of measures for neurologic conditions for national measurement programs. Methods: A process that has been used nationally for measure development was adapted for use by the AAN. Topics for measure development are chosen based upon national priorities, available evidence base from a systematic literature search, gaps in care, and the potential impact for quality improvement. A panel composed of subject matter and measure development methodology experts oversees the development of the measures. Recommendation statements and their corresponding level of evidence are reviewed and considered for development into draft candidate measures. The candidate measures are refined by the expert panel during a 30-day public comment period and by review by the American Medical Association for Current Procedural Terminology (CPT) II codes. All final AAN measures are approved by the AAN Board of Directors. Results: Parkinson disease (PD) was chosen for measure development. A review of the medical literature identified 258 relevant recommendation statements. A 28-member panel approved 10 quality measures for PD that included full specifications and CPT II codes. Conclusion: The AAN has adapted a measure development process that is suitable for national measurement programs and has demonstrated its capability to independently develop quality measures.

    2017-11-01

    Quality measures are tools used by physicians, health care systems, and payers to evaluate performance, monitor the outcomes of interventions, and inform quality improvement efforts. A paucity of quality measures exist that address hand surgery care. We completed a RAND/UCLA (University of California Los Angeles) Delphi Appropriateness process with the goal of developing and evaluating candidate hand surgery quality measures to be used for national quality measure development efforts. A consortium of 9 academic upper limb surgeons completed a RAND/UCLA Delphi Appropriateness process to evaluate the importance, scientific acceptability, usability, and feasibility of 44 candidate quality measures. These addressed hand problems the panelists felt were most appropriate for quality measure development. Panelists rated the measures on an ordinal scale between 1 (definitely not valid) and 9 (definitely valid) in 2 rounds (preliminary round and final round) with an intervening face-to-face discussion. Ratings from 1 to 3 were considered not valid, 4 to 6 as equivocal or uncertain, and 7 to 9 as valid. If no more than 2 of the 9 ratings were outside the 3-point range that included the median (1-3, 4-6, or 7-9), the panelists were considered to be in agreement. If 3 or more of the panelists' ratings of a measure were within the 1 to 3 range and 3 or more ratings were in the 7 to 9 range, the panelists were considered to be in disagreement. There was agreement on 43% (19) of the measures as important, 27% (12) as scientifically sound, 48% (21) as usable, and 59% (26) as feasible to complete. Ten measures met all 4 of these criteria and were, therefore, considered valid measurements of quality. Quality measures that were developed address outcomes (patient-reported outcomes for assessment and improvement of function) and processes of care (utilization rates of imaging, antibiotics, occupational therapy, ultrasound, and operative treatment).

    Background: The Institute of Medicine framework defines six dimensions of quality for healthcare systems: (1) safety, (2) effectiveness, (3) patient centeredness, (4) timeliness of care, (5) efficiency, and (6) equity. Large health datasets provide an opportunity to assess quality in these areas. Objective: To perform an international comparison of the measurability of the delivery of these aims, in people with type 2 diabetes mellitus (T2DM) from large datasets. Method: We conducted a survey to assess healthcare outcomes data quality of existing databases and disseminated this through professional networks. We examined the data sources used to collect the data, frequency of data uploads, and data types used for identifying people with T2DM. We compared data completeness across the six areas of healthcare quality, using selected measures pertinent to T2DM management. Results: We received 14 responses from seven countries (Australia, Canada, Italy, the Netherlands, Norway, Portugal, Turkey and the UK). Most databases reported frequent data uploads and would be capable of near real time analysis of healthcare quality.The majority of recorded data related to safety (particularly medication adverse events) and treatment efficacy (glycaemic control and microvascular disease). Data potentially measuring equity was less well recorded. Recording levels were lowest for patient-centred care, timeliness of care, and system efficiency, with the majority of databases containing no data in these areas. Databases using primary care sources had higher data quality across all areas measured. Conclusion: Data quality could be improved particularly in the areas of patient-centred care, timeliness, and efficiency. Primary care derived datasets may be most suited to healthcare quality assessment. Georg Thieme Verlag KG Stuttgart.

    2018-03-20

    Venous thromboembolism (VTE) is 1 of the most common causes of preventable harm for patients in hospitals. Consequently, the Joint Commission, the Centers for Medicare and Medicaid Services, the Agency for Healthcare Research and Quality, the United Kingdom Care Quality Commission, the Australian Commission on Safety and Quality in Health Care, the Maryland Health Services Cost Review Commission, and the American College of Surgeons have prioritized measuring and reporting VTE outcomes with the goal of reducing the incidence of and preventable harm from VTE. We developed a rubric for defect-free VTE prevention, graded each organizational VTE quality measure, and found that none of the current VTE-related quality measures adequately characterizes VTE prevention efforts or outcomes in hospitalized patients. Effective VTE prevention is multifactorial: clinicians must assess patients' risk for VTE and prescribe therapy appropriate for each patient's risk profile, patients must accept the prescribed therapy, and nurses must administer the therapy as prescribed. First, an ideal, defect-free VTE prevention process measure requires: (1) documentation of a standardized VTE risk assessment; (2) prescription of optimal, risk-appropriate VTE prophylaxis; and (3) administration of all risk-appropriate VTE prophylaxis as prescribed. Second, an ideal VTE outcome measure should define potentially preventable VTE as VTE that developed in patients who experienced any VTE prevention process failures. © 2018 American Heart Association, Inc.

    The data-quality objectives for samples collected at surface-water sites in the National Water-Quality Network include estimating the extent to which contamination, matrix effects, and measurement variability affect interpretation of environmental conditions. Quality-control samples provide insight into how well the samples collected at surface-water sites represent the true environmental conditions. Quality-control samples used in this program include field blanks, replicates, and field matrix spikes. This report describes the design for collection of these quality-control samples and the data management needed to properly identify these samples in the U.S. Geological Survey’s national database.

    Several ways of measuring spot quality are compared. We examine in detail various figures of merit such as full width at half maximum (FWHM), full width at 1/(e exp 2) maximum, Strehl ratio, and encircled energy. Our application is optical data storage, but results can be applied to other areas like space communications and high energy lasers. We found that the optimum figure of merit in many cases is Strehl ratio.

  1. Radiation measurements and quality control

    McLaughlin, W.L.

    1977-01-01

    Accurate measurements are essential to research leading to a successful radiation process and to the commissioning of the process and the facility. On the other hand, once the process is in production, the importance to quality control of measuring radiation quantities (i.e., absorbed dose, dose rate, dose distribution) rather than various other parameters of the process (i.e. conveyor speed, dwell time, radiation field characteristics, product dimensions) is not clearly established. When the safety of the product is determined by the magnitude of the administered dose, as in radiation sterilization, waste control, or food preservation, accuracy and precision of the measurement of the effective dose are vital. Since physical dose measurements are usually simpler, more reliable and reproducible than biological testing of the product, there is a trend toward using standardized dosimetry for quality control of some processes. In many industrial products, however, such as vulcanized rubber, textiles, plastics, coatings, films, wire and cable, the effective dose can be controlled satisfactorily by controlling process variables or by product testing itself. In the measurement of radiation dose profiles by dosimetry, it is necessary to have suitable dose meter calibrations, to account for sources of error and imprecision, and to use correct statistical procedures in specifying dwell times or conveyor speeds and source and product parameters to achieve minimum and maximum doses within specifications.

    To examine how different definitions of meals and snacks can affect the associations of meal frequency (MF) and snack frequency (SF) with dietary intake and adiposity measures. Based on 7 d weighed dietary record data, all eating occasions providing ≥210 kJ of energy were divided into meals or snacks based on contribution to energy intake (≥15 % or snacks, SF was associated with higher intakes of confectionery and alcohol, lower intakes of cereals, protein, fat and dietary fibre, and lower HDI (except for SF based on energy contribution in women) and MDS. After adjustment for potential confounders, MF based on time, but not MF based on energy contribution, was positively associated with BMI and waist circumference in men only. SF was positively associated with BMI and waist circumference, irrespective of the definition of snacks. Higher SF was consistently associated with lower diet quality and higher adiposity measures, while associations with MF varied depending on the definition of meals and sex.

  3. Quality assurance in biomarker measurement.

    Aitio, A; Apostoli, P

    1995-05-01

    Quality assurance (QA) concerns the validity of all the analytical processes (from collection of the samples to interpretation of the results). It is not an abstract concept but must be adapted to the different situations such as the different exposure levels, the different analytical methods, and the context of use (risk assessment procedures, research, routine determinations). The main requirements in QA programmes regard the control of all the known sources of preanalytical and analytical variations, while the instruments with which adequate QA can be implemented are the certified materials and the quality control programmes (quality manual, internal and external quality controls). Another important concept in QA is that measurements must be placed a different metrological levels: at the highest there are the methods (definitive, reference) to be used for assessing accuracy of routine methods. QA programmes should enable a grading of biomarkers (from experimental only to full evaluated) and of the laboratories in order to identify the significance of the test and to assess the level at which a laboratory could operate.

    Until recently, the quality of U.S. radioassay laboratory services has been evaluated by a limited number of governmental measurement assurance programs (MAPs). The major programs have been limited to the U.S. Department of Energy (DOE), the U.S. Environmental Protection Agency (EPA) and the U.S. Nuclear Regulatory Commission (NRC). In 1988, an industry MAP was established for the nuclear power utility industry through the U.S. Council for Energy Awareness/National Institute of Standards and Technology (USCEA/NIST). This program functions as both a MAP for utility laboratories and/or their commercial contractor laboratories, and as a traceability program for the U.S. radioactive source manufacturers and the utility laboratories. Each of these generic MAPs has been initiated and is maintained to serve the specific needs of the sponsoring agency or organization. As a result, there is diversification in their approach, scope, requirements, and degree of traceability to NIST. In 1987, a writing committee was formed under the American National Standards Institute (ANSI) N42.2 committee to develop a standard to serve as the basis document for the creation of a national measurement quality assurance (MQA) program for radioassay laboratories in the U.S. The standard is entitled, open-quotes Measurement Quality Assurance For Radioassay Laboratories.open-quotes The document was developed to serve as a guide for MQA programs maintained for the specialized sectors of the radioassay community, such as bioassay, routine environmental monitoring, environmental restoration and waste management, radiopharmaceuticals, and nuclear facilities.

In Denmark, extensive quality management initiatives have been implemented throughout hospitals, this was not the case in the Faroese Islands in 2013. The purpose of this study is to investigate the patient safety culture in the National Hospital of the Faroe Islands prior to implementation of quality management initiatives. Methods: The Danish version of the Safety Attitudes Questionnaire (SAQ-DK was distributed electronically to 557 staff members from five medical centers of the hospital, and one administrative unit. SAQ-DK has six cultural dimensions. The proportion of respondents with positive attitudes and mean scale scores were described, and comparison between medical specialties, and between clinical leaders and frontline staff was made using analysis of variance and chi-square test, respectively. Results: The response rate was 65.8% (N=367. Job satisfaction was rated most favorable, and the perceived culture of the top management least favorable. Safety climate was the dimension with the greatest variability across the 28 units. The diagnostic center had the most favorable culture of all centers. More leaders than frontline staff had positive attitudes toward teamwork and safety climate, and working conditions, respectively. Also, the leaders perceived these dimensions more positive than the frontline staff, P<0.05. Among three management levels

    Professional and advocacy organizations have long urged that dementia should be recognized and properly diagnosed. With the passage of the National Alzheimer's Project Act in 2011, an Advisory Council for Alzheimer's Research, Care, and Services was convened to advise the Department of Health and Human Services. In May 2012, the Council produced the first National Plan to address Alzheimer's disease, and prominent in its recommendations is a call for quality measures suitable for evaluating and tracking dementia care in clinical settings. Although other efforts have been made to set dementia care quality standards, such as those pioneered by RAND in its series Assessing Care of Vulnerable Elders (ACOVE), practitioners, healthcare systems, and insurers have not widely embraced implementation. This executive summary (full manuscript available at www.neurology.org) reports on a new measurement set for dementia management developed by an interdisciplinary Dementia Measures Work Group (DWG) representing the major national organizations and advocacy organizations concerned with the care of individuals with dementia. The American Academy of Neurology (AAN), the American Geriatrics Society, the American Medical Directors Association, the American Psychiatric Association, and the American Medical Association-convened Physician Consortium for Performance Improvement led this effort. The ACOVE measures and the measurement set described here apply to individuals whose dementia has already been identified and properly diagnosed. Although similar in concept to ACOVE, the DWG measurement set differs in several important ways; it includes all stages of dementia in a single measure set, calls for the use of functional staging in planning care, prompts the use of validated instruments in patient and caregiver assessment and intervention, highlights the relevance of using palliative care concepts to guide care before the advanced stages of illness, and provides evidence-based support

    This study aims to understand the adoption of clinical quality measurement throughout the United States on an EMS agency level, the features of agencies that do participate in quality measurement, and the level of physician involvement. It also aims to barriers to implementing quality improvement initiatives in EMS. A 46-question survey was developed to gather agency level data on current quality improvement practices and measurement. The survey was distributed nationally via State EMS Offices to EMS agencies nation-wide using Surveymonkey©. A convenience sample of respondents was enrolled between August and November, 2015. Univariate, bivariate and multiple logistic regression analyses were conducted to describe demographics and relationships between outcomes of interest and their covariates using SAS 9.3©. A total of 1,733 surveys were initiated and 1,060 surveys had complete or near-complete responses. This includes agencies from 45 states representing over 6.23 million 9-1-1 responses annually. Totals of 70.5% (747) agencies reported dedicated QI personnel, 62.5% (663) follow clinical metrics and 33.3% (353) participate in outside quality or research program. Medical director hours varied, notably, 61.5% (649) of EMS agencies had quality measures compared to fire-based agencies.

    Ensuring safe water supply for communities across the United States is a growing challenge in the face of aging infrastructure, impaired source water, and strained community finances. In the aftermath of the Flint lead crisis, there is an urgent need to assess the current state of US drinking water. However, no nationwide assessment has yet been conducted on trends in drinking water quality violations across several decades. Efforts to reduce violations are of national concern given that, in 2015, nearly 21 million people relied on community water systems that violated health-based quality standards. In this paper, we evaluate spatial and temporal patterns in health-related violations of the Safe Drinking Water Act using a panel dataset of 17,900 community water systems over the period 1982-2015. We also identify vulnerability factors of communities and water systems through probit regression. Increasing time trends and violation hot spots are detected in several states, particularly in the Southwest region. Repeat violations are prevalent in locations of violation hot spots, indicating that water systems in these regions struggle with recurring issues. In terms of vulnerability factors, we find that violation incidence in rural areas is substantially higher than in urbanized areas. Meanwhile, private ownership and purchased water source are associated with compliance. These findings indicate the types of underperforming systems that might benefit from assistance in achieving consistent compliance. We discuss why certain violations might be clustered in some regions and strategies for improving national drinking water quality.

    The sustainability of development is closely linked to changes in total per capita wealth. This paper presents estimates of the wealth of nations for nearly 100 countries, broken down into produced assets, natural resources and human resources. While the latter is the dominant form of wealth in virtually all countries, in low income natural resource exporters the share of natural resources in total wealth is equal to the share of produced assets. For low income countries in general, cropland forms the vast majority of natural wealth. The analysis suggests the process of development can be viewed as one of portfolio management: sustainable development entails saving the rents from exhaustible resources, managing renewable resources sustainably, and investing savings in both produced assets and human resources.

    Although the importance and advantages of measurement-based care in mental healthcare are well established, implementation in daily practice is complex and far from optimal. To accelerate the implementation of outcome measurement in routine clinical practice, a government-sponsored National Quality Improvement Collaborative was initiated in Dutch-specialised mental healthcare. To investigate the effects of this initiative, we combined a matched-pair parallel group design (21 teams) with a cluster randomised controlled trial (RCT) (6 teams). At the beginning and end, the primary outcome 'actual use and perceived clinical utility of outcome measurement' was assessed. In both designs, intervention teams demonstrated a significant higher level of implementation of outcome measurement than control teams. Overall effects were large (parallel group d =0.99; RCT d =1.25). The National Collaborative successfully improved the use of outcome measurement in routine clinical practice.

    2009-01-01

    By the end of the year 2007, pediatric hospitals in Baden-Württemberg had assigned themselves to one of three levels of perinatal care according to a checklist of the German Federal Joint Committee (F-JC) effective since January 1st, 2006. The Medical Service of Statutory Health Insurance had been assigned to prove the plausibility of that self-assessment according to quality criteria for clinical care of term and preterm newborn infants concordated by the F-JC. Between November 2007 and October 2008 31 providers were audited. Observations were documented in a checklist, reviewed and evaluated by expert auditors. For that purpose, quality criteria given by the F-JC were grouped into 7 quality categories which were weighted according to their practical relevance. In addition, a graded numeric system of evaluation was used for comparative analysis (absolute and relative benchmarking values). 3 of 23 providers fulfilled the quality criteria of the F-JC for PNC level 1 (highest level of care), 6 of 23 fulfilled them in part, and 14 of 23 did not fulfill them as judged by the auditors. Criteria for PNC level 2 were "fulfilled in part" by 2 of 6 providers and "not fulfilled" by 4. Both providers of perinatal special care ("level 3") fulfilled the quality criteria for "level 3" completely. There was no linear correlation between absolute or relative benchmarking values and assessment by expert auditors. If the criteria of the F-JC were interpreted very strictly, it would be difficult to guarantee comprehensive regional delivery of care in the state of Baden-Württemberg at the level formally requested by the F-JC for PNCs.

    Patients with multiple chronic conditions (MCCs) are a critical but undefined group for quality measurement. We present a generally applicable systematic approach to defining an MCC cohort of Medicare fee-for-service beneficiaries that we developed for a national quality measure, risk-standardized rates of unplanned admissions for Accountable Care Organizations. To define the MCC cohort we: (1) identified potential chronic conditions; (2) set criteria for cohort conditions based on MCC framework and measure concept; (3) applied the criteria informed by empirical analysis, experts, and the public; (4) described "broader" and "narrower" cohorts; and (5) selected final cohort with stakeholder input. Subjects were patients with chronic conditions. Participants included 21.8 million Medicare fee-for-service beneficiaries in 2012 aged 65 years and above with ≥1 of 27 Medicare Chronic Condition Warehouse condition(s). In total, 10 chronic conditions were identified based on our criteria; 8 of these 10 were associated with notably increased admission risk when co-occurring. A broader cohort (2+ of the 8 conditions) included 4.9 million beneficiaries (23% of total cohort) with an admission rate of 70 per 100 person-years. It captured 53% of total admissions. The narrower cohort (3+ conditions) had 2.2 million beneficiaries (10%) with 100 admissions per 100 person-years and captured 32% of admissions. Most stakeholders viewed the broader cohort as best aligned with the measure concept. By systematically narrowing chronic conditions to those most relevant to the outcome and incorporating stakeholder input, we defined an MCC admission measure cohort supported by stakeholders. This approach can be used as a model for other MCC outcome measures.

  8. Health Care Quality: Measuring Obesity in Performance Frameworks.

    Zvenyach, Tracy; Pickering, Matthew K

    2017-08-01

    Obesity affects over one-third of Americans and leads to several chronic and costly comorbid conditions. The national movement toward value-based care calls for a refocusing of efforts to address the US obesity epidemic. To help set the stage, the current landscape of obesity-specific quality measures was evaluated. Seven quality measure databases and nine professional societies were searched. Inclusion and exclusion criteria were applied. Measures were then classified by domain and by implementation in national public programs. Eleven obesity-specific quality measures in adults were identified (nine process and two outcome). Three measures received National Quality Forum (NQF) endorsement. Two measures were actively used within Centers for Medicare and Medicaid Services (CMS) programs. Only one measure was both NQF-endorsed and used by CMS. Limitations exist with respect to obesity-specific quality metrics. Such gaps provide opportunities for obesity care specialists to engage and offer valuable insights and pragmatic approaches toward quality measurement. © 2017 The Obesity Society.

  9. Measuring quality of care: considering conceptual approaches to quality indicator development and evaluation.

    Science.gov (United States)

    Stelfox, Henry T; Straus, Sharon E

    2013-12-01

    In this article, we describe one approach for developing and evaluating quality indicators. We focus on describing different conceptual approaches to quality indicator development, review one approach for developing quality indicators, outline how to evaluate quality indicators once developed, and discuss quality indicator maintenance. The key steps for developing quality indicators include specifying a clear goal for the indicators; using methodologies to incorporate evidence, expertise, and patient perspectives; and considering contextual factors and logistics of implementation. The Strategic Framework Board and the National Quality Measure Clearinghouse have developed criteria for evaluating quality indicators that complement traditional psychometric evaluations. Optimal strategies for quality indicator maintenance and dissemination have not been determined, but experiences with clinical guideline maintenance may be informative. For quality indicators to effectively guide quality improvement efforts, they must be developed, evaluated, maintained, and implemented using rigorous evidence-informed practices.

    1984-10-01

    This handbook provides guidance in the application of quality assurance to measurement activities. It is intended to help those persons making measurements in applying quality assurance to their work activities by showing how laboratory practices and quality assurance requirements are integrated to provide control within those activities. The use of the guidance found in this handbook should help provide consistency in the interpretation of quality assurance requirements across all types of measurement laboratories. This handbook also can assist quality assurance personnel in understanding the relationships between laboratory practices and quality assurance requirements. The handbook is composed of three chapters and several appendices. Basic guidance is provided by the three chapters. In Chapter 1, the role of quality assurance in obtaining quality data and the importance of such data are discussed. Chapter 2 presents the elements of laboratory quality assurance in terms of practices that can be used in controlling work activities to assure the acquisition of quality data. Chapter 3 discusses the implementation of laboratory quality assurance. The appendices provide supplemental information to give the users a better understanding of the following: what is quality assurance; why quality assurance is required; where quality assurance requirements come from; how those requirements are interpreted for application to laboratory operations; how the elements of laboratory quality assurance relate to various laboratory activities; and how a quality assurance program can be developed

    Full Text Available We utilize two basic approaches to measure the quality of earnings which control two different dimensions of earnings management. The research design is structured primary on the basis of calculating two different measures of the quality of earnings on the industry level and on the company level. We calculate earnings quality for New Zealand public firms from the OSIRIS (http://www.osiris.com database for 2004-2007. This research concludes that various stakeholders should apply more than one measure for the quality of earning in order to have strong evidence about the level of quality before taking any corrective action or making any decision related to that company. If one company is having low quality of earning according to one technique and high quality of earnings according to another, the stakeholders cannot have a final conclusion about that company and they need more investigations and analysis to assess the quality of earnings

    A quality assurance programme at the National Calibration Laboratory for ionizing radiation in Tanzania is described. The programme focuses mainly on regular stability check source and reference output measurements, performance testing of TLD systems as well as some external audit checks. It is found that the stability check source measurements are within ± 1%. Similarly, the air kerma rate measurements agree well with calibration uncertainties, that is ± 2% for protection level measurements and ± 1.5% for clinical dosimetry. The results of comparison of dose measurements done on site and those obtained from some external audit checks are also within requirements. This shows that the working standards have been kept with good care, and that the traceability to the international measurement system is adequately maintained. Some examples on calibration transfer activities are briefly discussed

    Bashir M Matata

    2013-09-01

    Full Text Available Objectives: To explore patients’ views on the EuroQol-5D and Coronary Revascularisation Outcome Questionnaire, tools currently used for collecting patient-reported outcome measures in the English National Health Service. The key questions were as follows: (1 whether patients consider them sensitive enough to detect change in their health after cardiovascular disease interventions and (2 whether they consider the health-related quality-of-life questions as meaningful. Methods: Data were collected on patients’ views using focus groups. We held four focus groups selecting participants on the basis of their baseline and follow-up EuroQol-5D scores. Data were analysed using framework analysis and grounded theory. Results: Focus group participants confirmed that they had derived substantial health benefits from their cardiac interventions despite the lack of measurable effects on the EuroQol-5D scores. Participants felt that the EuroQol-5D questionnaire was limited because of the following reasons: Their health fluctuates from day to day. They had difficulty assessing their general health status on the visual analogue scale. They felt that the Coronary Revascularisation Outcome Questionnaire was limited because of the following reasons: They did not understand the clinical terms used. The impact of tiredness on their quality of life was not captured. They were unable to distinguish between the effects of their heart condition and other health issues. Additionally, neither questionnaire considers the adjustments people have made to their domestic arrangements to improve their health-related quality of life. Conclusion: This study provides evidence that the two questionnaires do not capture some aspects of health that patients consider important. Furthermore, the presence of co-morbidities masks the symptoms relating to the heart disease and the effect of their cardiac interventions. Future work on patient-reported outcome measures should consider

    A PDP 11/35 computer system is used in evaluating analytical chemistry measurements quality control data at the Barnwell Nuclear Fuel Plant. This computerized measurement quality control system has several features which are not available in manual systems, such as real-time measurement control, computer calculated bias corrections and standard deviation estimates, surveillance applications, evaluaton of measurement system variables, records storage, immediate analyst recertificaton, and the elimination of routine analysis of known bench standards. The effectiveness of the Barnwell computer system has been demonstrated in gathering and assimilating the measurements of over 1100 quality control samples obtained during a recent plant demonstration run. These data were used to determine equaitons for predicting measurement reliability estimates (bias and precision); to evaluate the measurement system; and to provide direction for modification of chemistry methods. The analytical chemistry measurement quality control activities represented 10% of the total analytical chemistry effort

    2017-01-01

    As health care reimbursements based on pay-for-performance models become more common, there is an unprecedented demand for ways to measure health care quality and demonstrate value. Performance measures, a type of quality measure, are unique tools in a health care delivery system that allow objective monitoring of adherence to specific goals and tracking of outcomes. We sought to provide information on the development of quality measures in otolaryngology–head and neck surgery, as well as the goals of performance measurement at a national level and for our specialty. The historical development, various types, and approach to creating effective performance measures are discussed. The primary methods of developing performance measures (using clinical practice guidelines, clinical registries, and alternative methods) are also discussed. Performance measures are an important tool that can aid otolaryngologists in achieving effective, efficient, equitable, timely, safe, and patient-centered care as outlined by the Institute of Medicine.

  3. Quality of antenatal care in Zambia: a national assessment

    Science.gov (United States)

    2012-01-01

    Background Antenatal care (ANC) is one of the recommended interventions to reduce maternal and neonatal mortality. Yet in most Sub-Saharan African countries, high rates of ANC coverage coexist with high maternal and neonatal mortality. This disconnect has fueled calls to focus on the quality of ANC services. However, little conceptual or empirical work exists on the measurement of ANC quality at health facilities in low-income countries. We developed a classification tool and assessed the level of ANC service provision at health facilities in Zambia on a national scale and compared this to the quality of ANC received by expectant mothers. Methods We analysed two national datasets with detailed antenatal provider and user information, the 2005 Zambia Health Facility Census and the 2007 Zambia Demographic and Health Survey (DHS), to describe the level of ANC service provision at 1,299 antenatal facilities in 2005 and the quality of ANC received by 4,148 mothers between 2002 and 2007. Results We found that only 45 antenatal facilities (3%) fulfilled our developed criteria for optimum ANC service, while 47% of facilities provided adequate service, and the remaining 50% offered inadequate service. Although 94% of mothers reported at least one ANC visit with a skilled health worker and 60% attended at least four visits, only 29% of mothers received good quality ANC, and only 8% of mothers received good quality ANC and attended in the first trimester. Conclusions DHS data can be used to monitor “effective ANC coverage” which can be far below ANC coverage as estimated by current indicators. This “quality gap” indicates missed opportunities at ANC for delivering effective interventions. Evaluating the level of ANC provision at health facilities is an efficient way to detect where deficiencies are located in the system and could serve as a monitoring tool to evaluate country progress.

  4. Earnings Quality Measures and Excess Returns.

    Perotti, Pietro; Wagenhofer, Alfred

    2014-06-01

    This paper examines how commonly used earnings quality measures fulfill a key objective of financial reporting, i.e., improving decision usefulness for investors. We propose a stock-price-based measure for assessing the quality of earnings quality measures. We predict that firms with higher earnings quality will be less mispriced than other firms. Mispricing is measured by the difference of the mean absolute excess returns of portfolios formed on high and low values of a measure. We examine persistence, predictability, two measures of smoothness, abnormal accruals, accruals quality, earnings response coefficient and value relevance. For a large sample of US non-financial firms over the period 1988-2007, we show that all measures except for smoothness are negatively associated with absolute excess returns, suggesting that smoothness is generally a favorable attribute of earnings. Accruals measures generate the largest spread in absolute excess returns, followed by smoothness and market-based measures. These results lend support to the widespread use of accruals measures as overall measures of earnings quality in the literature.

    2010-01-01

    After Chernobyl accident in 1986, the government began to implement mechanisms to ensure the quality of measurements of environmental radioactivity and to assure the transparency of information on environmental radioactivity monitoring results. Within this context, the French National Network for the Measurement of Environmental Radioactivity (RNM), is created in 2002 under the Public Health Code. This network is developed under the auspices of ASN in collaboration with IRSN and in partnership with government departments, major nuclear licensees, health agencies and environmental protection associations. In order to centralize information on environmental radioactivity and to provide access to measurement results, a single database that includes an the results of measurements of radioactivity in the environment on the national territory is build and a new web-site www.mesure-radioactivite.fr is launched. It provides quick and easy access to this database. The quality of measurements is performed by a laboratory system through an ASN decision. Novel initiative in Europe, the French National Network for the Measurement of Environmental Radioactivity web-site gives the user keys to understand the measurement results on the radiological state of the environment. The site will be improved over the time taking into account the feedback of the users. (author)

    2014-01-01

    For several years, the use of administrative data in mandatory quality measurement has been requested by several stakeholders in Germany. Main advantages of using administrative data include the reduction of documentary expenditures and the possibility to perform longitudinal quality analyses across different healthcare units. After a short introduction, a brief overview of the current use of administrative data for mandatory quality assurance as well as current developments is given, which will then be further exemplified by decubital ulcer prophylaxis. By using administrative data coding expenditures in this clinical area could be reduced by nine million data fields. At the same time the population analysed was expanded resulting in a more than tenfold increase in potentially quality-relevant events. Finally, perspectives, further developments, possibilities as well as limits of quality measurement with administrative data are discussed. Copyright © 2014. Published by Elsevier GmbH.

    Work procedures based upon dependable measurements have unquestionably reduced past exposures to a level that will produce few injuries in later years. Of the many legal issues that might be discussed with regard to instrument calibration, the two of present concern are the determination of cause, and the evidence (including expert testimony) submitted to that end. Although they are termed here legal issues, they are in fact highly technical problems which have recently become political footballs. Some background is discussed in order to understand how such legal/technical/political considerations are related to instrument calibration, the subject of this workshop

    2018-06-01

    There is growing interest in the quality of health care delivery in liver transplantation. Multiple stakeholders, including patients, transplant providers and their hospitals, payers, and regulatory bodies have an interest in measuring and monitoring quality in the liver transplant process, and understanding differences in quality across centres. This article aims to provide an overview of quality measurement and regulatory issues in liver transplantation performed within the United States. We review how broader definitions of health care quality should be applied to liver transplant care models. We outline the status quo including the current regulatory agencies, public reporting mechanisms, and requirements around quality assurance and performance improvement (QAPI) activities. Additionally, we further discuss unintended consequences and opportunities for growth in quality measurement. Quality measurement and the integration of quality improvement strategies into liver transplant programmes hold significant promise, but multiple challenges to successful implementation must be addressed to optimise value.

  6. [Comparative quality measurements part 3: funnel plots].

    Science.gov (United States)

    Kottner, Jan; Lahmann, Nils

    2014-02-01

    Comparative quality measurements between organisations or institutions are common. Quality measures need to be standardised and risk adjusted. Random error must also be taken adequately into account. Rankings without consideration of the precision lead to flawed interpretations and enhances "gaming". Application of confidence intervals is one possibility to take chance variation into account. Funnel plots are modified control charts based on Statistical Process Control (SPC) theory. The quality measures are plotted against their sample size. Warning and control limits that are 2 or 3 standard deviations from the center line are added. With increasing group size the precision increases and so the control limits are forming a funnel. Data points within the control limits are considered to show common cause variation; data points outside special cause variation without the focus of spurious rankings. Funnel plots offer data based information about how to evaluate institutional performance within quality management contexts.

    Health-related quality of life (HRQOL) represents an individual's perception of physical, mental, and social well-being and is a strong predictor of health status. Few studies have examined associations of sedentary behavior (SB) and moderate-to-vigorous physical activity (MVPA) with HRQOL in the general population. This study aimed to determine combined associations of objectively measured SB and MVPA on the risk of poor HRQOL in the general US population, after controlling for potential confounding factors. We analyzed data from 5359 adults from the National Health and Nutrition Examination Survey 2003-2006. HRQOL was measured using a HRQOL-4 consisting of four questions focused on the self-perception of general health, physical health, mental health, and activity limitation. We dichotomized each HRQOL-4 component as good versus poor and defined poor overall HRQOL when participants had any poor HRQOL components. SB and MVPA were measured using an accelerometer. Survey logistic models were examined to estimate the odds ratio (OR) and 95% confidence interval (CI) for poor HRQOL by SB and MVPA as tertiles. When examined as a combination of SB and MVPA, a substantial decrease in the risk of poor overall HRQOL was found in individuals with low SB/high MVPA [OR 0.69 (95% CI 0.51-0.94) and moderate SB/high MVPA (OR 0.56 (95% CI 0.40-0.78)], but no significant decrease was found in individuals with high SB/high MVPA (vs. high SB/low MVPA). Our findings suggest that both increasing MVPA and reducing time spent in SB may be useful strategies to improve HRQOL.

    In this study, we investigated the adoptability of software quality measures for healthcare process measurement. Quality measures of ISO/IEC 9126 are redefined from a process perspective to build a generic healthcare process quality measurement model. Case study research method is used, and the model is applied to a public hospital's Entry to Care process. After the application, weak and strong aspects of the process can be easily observed. Access audibility, fault removal, completeness of documentation, and machine utilization are weak aspects and these aspects are the candidates for process improvement. On the other hand, functional completeness, fault ratio, input validity checking, response time, and throughput time are the strong aspects of the process.

    Starting with clinically motivated projects, the national quality assurance program has established a legislative obligatory framework. Annual feedback of results is an important means of quality control. The annual reports cover quality-related information with high granularity. A synopsis for corporate management is missing, however. Therefore, the results of the University Clinics in Greifswald, Germany, have been analyzed and aggregated to support hospital management. Strengths were identified by the ranking of results within the state for each quality indicator, weaknesses by the comparison with national reference values. The assessment was aggregated per clinical discipline and per category (indication, process, and outcome). A composition of quality indicators was claimed multiple times. A coherent concept is still missing. The method presented establishes a plausible summary of strengths and weaknesses of a hospital from the point of view of the national quality assurance program. Nevertheless, further adaptation of the program is needed to better assist corporate management.

    TLD technique characterized by high precision and reproducibility of dose measurement is presented by addressing pre-readout annealing, group sorting, dose evaluation, blind tests, internal dose quality audit and external quality control audits. Two hundred and forty TLD chips were annealed for 1 hour at 4000 degree C followed by 2 h at 1000 degree C. After exposure of 1 mGy from 90 Sr irradiator TLDs were subjected to pre-readout annealing at 1000 degree C, then readout, sorted into groups each with nearly equal sensitivity. Upon repeating the procedures, TLDs having response >3.5% from group mean were dropped to assuring group stability. Effect of pre-readout annealing has been studied. Series of repeated measurements were conducted to stabilize calibration procedures and DCF generation using SSDL level 137 Cs calibrator, dose master, ionization chambers.

    The Triple Aim: improving healthcare quality, cost and patient experience has resulted in massive healthcare "quality" measurement. For many surgeons the origins, intent and strengths of this measurement barrage seems nebulous-though their shortcomings are noticeable. This article reviews the major organizations and programs (namely the Centers for Medicare and Medicaid Services) driving the somewhat burdensome healthcare quality climate. The success of this top-down approach is mixed, and far from convincing. We contend that the current programs disproportionately reflect the definitions of quality from (and the interests of) the national payer perspective; rather than a more balanced representation of all stakeholders interests-most importantly, patients' beneficence. The result is an environment more like performance management than one of valid quality assessment. Suggestions for a more meaningful construction of surgical quality measurement are offered, as well as a strategy to describe surgical quality from all of the stakeholders' perspectives. Our hope is to entice surgeons to engage in institution level quality improvement initiatives that promise utility and are less utopian than what is currently present. Copyright © 2017 Elsevier Inc.

    The quality assurance of treatment measures is legally required but as yet not generally established in practice. For interventional radiology, the introduction of quality assurance for PTA of arteries of the lower limbs is planned for January 1999. It is reasonable to subject at least the most important and/or most frequently performed interventions to quality management. In the present article, the term quality in the management of diseases is defined and the system of total quality management discussed at the levels structure, process, and results. For its application, parameters of quality measurement in the form of standards, criteria, and characteristic values are necessary and must be laid down by a team of experts on the basis of subjective experience and/or results in the literature. Practical quality assurance takes place not only within a clinic but also externally by comparison with other centers. Data collection and evaluation requires high-performance software that will be continuously improved, expanded, and adapted to current needs during regular meetings between the various users. (orig.)

  17. Quality assurance in field radiation measurements

    International Nuclear Information System (INIS)

    Howell, W.P.

    1985-01-01

    In most cases, an ion chamber radiation measuring instrument is calibrated in a uniform gamma radiation field. This results in a uniform ionization field throughout the ion chamber. Measurement conditions encountered in the field often produce non-uniform ionization fields within the ion chamber, making determination of true dose rates to personnel difficult and prone to error. Extensive studies performed at Hanford have provided appropriate correction factors for use with one type of ion chamber instrument, the CP. Suitable corrections are available for the following distinct measurement circumstances: (1) contact measurements on large beta and gamma sources, (2) contact measurements on small beta and gamma sources, (3) contact measurements on small-diameter cylinders, (4) measurements in small gamma beams, and (5) measurements at a distance from large beta sources. Recommendations are made for the implementation of these correction factors, in the interest of improved quality assurance in field radiation measurements. 12 references, 10 figures

    Groundwater-quality data were collected from 748 wells as part of the National Water-Quality Assessment Project of the U.S. Geological Survey National Water-Quality Program from May 2012 through December 2013. The data were collected from four types of well networks: principal aquifer study networks, which assess the quality of groundwater used for public water supply; land-use study networks, which assess land-use effects on shallow groundwater quality; major aquifer study networks, which assess the quality of groundwater used for domestic supply; and enhanced trends networks, which evaluate the time scales during which groundwater quality changes. Groundwater samples were analyzed for a large number of water-quality indicators and constituents, including major ions, nutrients, trace elements, volatile organic compounds, pesticides, and radionuclides. These groundwater quality data are tabulated in this report. Quality-control samples also were collected; data from blank and replicate quality-control samples are included in this report.

    Full Text Available Business process modelling and analysing is undoubtedly one of the most important parts of Applied (Business Informatics. Quality of business process models (diagrams is crucial for any purpose in this area. The goal of a process analyst’s work is to create generally understandable, explicit and error free models. If a process is properly described, created models can be used as an input into deep analysis and optimization. It can be assumed that properly designed business process models (similarly as in the case of correctly written algorithms contain characteristics that can be mathematically described. Besides it will be possible to create a tool that will help process analysts to design proper models. As part of this review will be conducted systematic literature review in order to find and analyse business process model’s design and business process model’s quality measures. It was found that mentioned area had already been the subject of research investigation in the past. Thirty-three suitable scietific publications and twenty-two quality measures were found. Analysed scientific publications and existing quality measures do not reflect all important attributes of business process model’s clarity, simplicity and completeness. Therefore it would be appropriate to add new measures of quality.

    2016-09-01

    Measuring and monitoring overall health system performance is complex and challenging but is crucial to improving quality of care. Today's health care organizations are increasingly being held accountable to develop and implement actions aimed at improving the quality of care, reducing costs, and achieving better patient-centered care. This paper describes the development of the Collaborative for Excellence in Healthcare Quality (CEHQ), a 5-year initiative to achieve higher quality of patient care in university hospitals across Canada. This bottom-up initiative took place between 2010 and 2015, and was successful in engaging health care leaders in the development of a common framework and set of performance measures for reporting and benchmarking, as well as working on initiatives to improve performance. Despite its successes, future efforts are needed to provide clear national leadership on standards for measuring performance. Copyright © 2016 The Authors. Published by Elsevier Ireland Ltd..

    1993-01-01

    Benthic algae (periphyton) and phytoplankton communities are characterized in the U.S. Geological Survey's National Water-Quality Assessment Program as part of an integrated physical, chemical, and biological assessment of the Nation's water quality. This multidisciplinary approach provides multiple lines of evidence for evaluating water-quality status and trends, and for refining an understanding of the factors that affect water-quality conditions locally, regionally, and nationally. Water quality can be characterized by evaluating the results of qualitative and quantitative measurements of the algal community. Qualitative periphyton samples are collected to develop of list of taxa present in the sampling reach. Quantitative periphyton samples are collected to measure algal community structure within selected habitats. These samples of benthic algal communities are collected from natural substrates, using the sampling methods that are most appropriate for the habitat conditions. Phytoplankton samples may be collected in large nonwadeable streams and rivers to meet specific program objectives. Estimates of algal biomass (chlorophyll content and ash-free dry mass) also are optional measures that may be useful for interpreting water-quality conditions. A nationally consistent approach provides guidance on site, reach, and habitat selection, as well as information on methods and equipment for qualitative and quantitative sampling. Appropriate quality-assurance and quality-control guidelines are used to maximize the ability to analyze data locally, regionally, and nationally.

    The aim of the paper is to review the main aspects of quality control of radiological devices according to the current national regulations. Explanation of the physical principles of image formation by different test phantoms used to measure focal spot sizes is presented in appendix. The obligation for quality assurance (QA) for all X-ray systems which follows European standards was enforced in updated '' Atomic Law Act '' of 29 November 2000 . This document is the main regulatory act which establishes the basic safety standards for radiation protection in Poland. The main modifications introduced by this new Act concerned the issue of radiation protection of individuals undergoing medical examinations with the use of ionizing radiation which is regulated by EC Directive 97/43 Euratom. According to this Directive quality assurance programmes, including quality control measures need to be implemented by the holder of the radiological installation. Therefore, in the above Act the Minister of Health has been obligated to impose specific regulations describing the way of implementation of general principles laid down in the Directive. Some of these regulations, like those concerning QC tests and tolerances, have already been mentioned in the document titled '' On the conditions for safe application of ionizing radiation in medicine ''. For example, the QC program in radiography is being considered; the obligatory tests- acceptance, routine and annual- are discussed and specific procedures are being indicated. The main idea of the document '' On the conditions for safe application of ionizing radiation in medicine '' which concerns radiation protection of patients and staff against ionizing radiation used in medicine is to implement the surveillance of all X-ray systems in form of acceptance tests followed by internal tests (routine and annual) performed in accordance with European standards.

    We adapted a rapid quality of care monitoring method to a fragile state with two aims: to assess the delivery of child health services in South Sudan at the time of independence and to strengthen local capacity to perform regular rapid health facility assessments. Using a two-stage lot quality assurance sampling (LQAS) design, we conducted a national cross-sectional survey among 156 randomly selected health facilities in 10 states. In each of these facilities, we obtained information on a range of access, input, process and performance indicators during structured interviews and observations. Quality of care was poor with all states failing to achieve the 80% target for 14 of 19 indicators. For example, only 12% of facilities were classified as acceptable for their adequate utilisation by the population for sick-child consultations, 16% for staffing, 3% for having infection control supplies available and 0% for having all child care guidelines. Health worker performance was categorised as acceptable in only 6% of cases related to sick-child assessments, 38% related to medical treatment for the given diagnosis and 33% related to patient counselling on how to administer the prescribed drugs. Best performance was recorded for availability of in-service training and supervision, for seven and ten states, respectively. Despite ongoing instability, the Ministry of Health developed capacity to use LQAS for measuring quality of care nationally and state-by-state, which will support efficient and equitable resource allocation. Overall, our data revealed a desperate need for improving the quality of care in all states. © 2014 John Wiley & Sons Ltd.

  7. A national look at water quality

    Gilliom, Robert J.; Mueller, David K.; Zogorski, John S.; Ryker, Sarah J.

    2002-01-01

    Most water-quality problems we face today result from diffuse "nonpoint" sources of pollution from agricultural land, urban development, forest harvesting and the atmosphere (U.S. Army Corps of Engineers et al., 1999). It is difficult to quantify nonpoint sources because the contaminants they deliver vary in composition and concentrations from hour to hour and season to season. Moreover, the nature of the contamination is complex and varied. When Congress enacted the Clean Water Act 30 years ago, attention was focused on water-quality issues related to the sanitation of rivers and streams - bacteria counts, oxygen in the water for fish, nutrients, temperature, and salinity. Now, attention is turning to the hundreds of synthetic organic compounds like pesticides used in agricultural and residential areas, volatile organics in solvents and gasoline, microbial and viral contamination, and pharmaceuticals and hormones.

    Osteoporosis becomes largely one of the most important socially significant and costly diseases. Modern techniques (DXA, US) are applied for bone densitometry. The paper presents a protocol for quality assurance especially of DXA-bone densitometers including quality control made in compliance with international standards (ISCD, IOF). The methodology has been tested in practice by measurements on site-functional assessment, entrance dose, radiation protection, calibration, in-vitro precision. It is expected to raise the quality of the diagnostic process in concert with the EU Medical Directive 97/43 particularly for population screening and sensitive groups. The protocol is an essential part of the National Program for constraining osteoporosis which has been elaborated at the Ministry of Health and at present under implementation throughout the country. It aims at reducing the risk, factors spreading, at diminishing the fracture risk the morbidity and the mortality from osteoporosis. An integral multidisciplinary approach to the problem solving is applied as well as training on three levels — doctors, patients, population, which effectively will contribute for obtaining real results in preventing osteoporosis.

  9. Managing air quality in a rapidly developing nation: China

    Science.gov (United States)

    Fang, Ming; Chan, Chak K.; Yao, Xiaohong

    As the world gets ready to begin the second decade of the twenty-first century, global climate change has been recognized as a real threat to civilization as we know it. The rapid and successful economic growth of developing nations, particularly China and India, is contributing to climate change. The route to initial economic success in China followed that of the developed nations through the development of industries. Unfortunately, China's environmental protection efforts have not been the same as in developed countries because China is vastly different culturally, socially, economically and, especially, politically from developed nations. When China started to deal with environmental concerns in the late 1970s, it took advantage of the experiences of other countries in establishing environmental standards and regulations, but it did not have a model to follow when it came to implementing these standards and regulations because of the abovementioned differences. Economically, China is transitioning from an agricultural base into an industrial base; however, even now, 60% of the population remains farmers. China has been and still is heavily dependent upon coal for energy, resulting in serious atmospheric particulate pollution. While growing efforts have been expended on the environment, at this juncture of its economic development, China would be well served to revisit the traditional "develop first and clean up later" approach and to find a balance between development and protecting the environment. Against this backdrop, a reflective look of the effort to manage air quality from 1949-2008 (with an emphasis on the past 30 years) in China is presented in this paper. The environmental component of the 2008 Olympic Games is examined as a special example to illustrate the current measures being used to improve air quality in China.

  11. Composite measures of watershed health from a water quality perspective.

    Science.gov (United States)

    Mallya, Ganeshchandra; Hantush, Mohamed; Govindaraju, Rao S

    2018-05-15

    Water quality data at gaging stations are typically compared with established federal, state, or local water quality standards to determine if violations (concentrations of specific constituents falling outside acceptable limits) have occurred. Based on the frequency and severity of water quality violations, risk metrics such as reliability, resilience, and vulnerability (R-R-V) are computed for assessing water quality-based watershed health. In this study, a modified methodology for computing R-R-V measures is presented, and a new composite watershed health index is proposed. Risk-based assessments for different water quality parameters are carried out using identified national sampling stations within the Upper Mississippi River Basin, the Maumee River Basin, and the Ohio River Basin. The distributional properties of risk measures with respect to water quality parameters are reported. Scaling behaviors of risk measures using stream order, specifically for the watershed health (WH) index, suggest that WH values increased with stream order for suspended sediment concentration, nitrogen, and orthophosphate in the Upper Mississippi River Basin. Spatial distribution of risk measures enable identification of locations exhibiting poor watershed health with respect to the chosen numerical standard, and the role of land use characteristics within the watershed.

  12. The quality of measurements a metrological reference

    CERN Document Server

    Fridman, A E

    2012-01-01

    This book provides a detailed discussion and commentary on the fundamentals of metrology. The fundamentals of metrology, the principles underlying the design of the SI International System of units, the theory of measurement error, a new methodology for estimation of measurement accuracy based on uncertainty, and methods for reduction of measured results and estimation of measurement uncertainty are all discussed from a modern point of view. The concept of uncertainty is shown to be consistent with the classical theory of accuracy. The theory of random measurement errors is supplemented by a very general description based on the generalized normal distribution; systematic instrumental error is described in terms of a methodology for normalizing the metrological characteristics of measuring instruments. A new international system for assuring uniformity of measurements based on agreements between national metrological institutes is discussed, in addition to the role and procedure for performance of key compari...

    Kriete, A; Naim, M; Schafer, L

    2001-01-01

    We describe a new method for the estimation of image quality in image restoration applications. We demonstrate this technique on a simulated data set of fluorescent beads, in comparison with restoration by three different deconvolution methods. Both the number of iterations and a regularisation factor are varied to enforce changes in the resulting image quality. First, the data sets are directly compared by an accuracy measure. These values serve to validate the image quality descriptor, which is developed on the basis of optical information theory. This most general measure takes into account the spectral energies and the noise, weighted in a logarithmic fashion. It is demonstrated that this method is particularly helpful as a user-oriented method to control the output of iterative image restorations and to eliminate the guesswork in choosing a suitable number of iterations.

  17. Air quality measurements for site characterization

    International Nuclear Information System (INIS)

    Carter, M.W.; Conklin, W.C.

    1982-01-01

    Effective and timely site characterization is an important part of selecting a site for low-level waste disposal. Parameters measured can be compared with pertinent regulatory requirements, used for a reference base, helpful in evaluating environmental impacts, utilized in documenting changes in control programs, of value in modeling studies and other data uses, and beneficial in providing relevant sampling and methodology training. This paper will focus on specific air quality measurements which should be an inherent part of the site characterization program. The program is designed to measure, quantify, and identify contributions from site uses (operational procedures), atmospheric fallout, natural radioactivity, and vicinity and regional applications of radionuclides. The recommended air quality measurements program will be described in association with a reference site developd by the US Nuclear Regulatory Commission. Particular attention will be devoted to the type and quality of information which is needed, the scope of sampling and measurements, the frequency of measurements, locations and numbers of sampling stations, the period of time needed for site characterization, and the proper uses of the information once it has been obtained. Adequate characterization of the site will be most important in final site selection and in the operation of the site as to periodically assessing environmental impacts and helping guide any remedial control efforts designed to meet regulatory requirements

    Full Text Available Abstract Background Breast cancer in women is increasingly frequent, and care is complex, onerous and expensive, all of which lend urgency to improvements in care. Quality measurement is essential to monitor effectiveness and to guide improvements in healthcare. Methods Ten databases, including Medline, were searched electronically to identify measures assessing the quality of breast cancer care in women (diagnosis, treatment, followup, documentation of care. Eligible studies measured adherence to standards of breast cancer care in women diagnosed with, or in treatment for, any histological type of adenocarcinoma of the breast. Reference lists of studies, review articles, web sites, and files of experts were searched manually. Evidence appraisal entailed dual independent assessments of data (e.g., indicators used in quality measurement. The extent of each quality indicator's scientific validation as a measure was assessed. The American Society of Clinical Oncology (ASCO was asked to contribute quality measures under development. Results Sixty relevant reports identified 58 studies with 143 indicators assessing adherence to quality breast cancer care. A paucity of validated indicators (n = 12, most of which assessed quality of life, only permitted a qualitative data synthesis. Most quality indicators evaluated processes of care. Conclusion While some studies revealed patterns of under-use of care, all adherence data require confirmation using validated quality measures. ASCO's current development of a set of quality measures relating to breast cancer care may hold the key to conducting definitive studies.

    Cole, Elizabeth F.; Morris, E.E.

    1986-01-01

    Surface water and groundwater quality was documented in the Ouachita National Forest by collecting surface water quality data at 15 points and groundwater quality data at 11 sites from April 1984 through August 1985. The data were compared to drinking water standards and the results are tabulated. Surface water in the Ouachita National Forest is relatively abundant. It is low in mineralization and chemically suitable for most uses with minimal treatment. Groundwater is relatively scarce. The low yields of wells limit the use of groundwater primarily to domestic use. The water is chemically suitable for most purposes but may require treatment for the removal of iron. (Peters-PTT)

  4. Adaptive measurements of urban runoff quality

    Wong, Brandon P.; Kerkez, Branko

    2016-11-01

    An approach to adaptively measure runoff water quality dynamics is introduced, focusing specifically on characterizing the timing and magnitude of urban pollutographs. Rather than relying on a static schedule or flow-weighted sampling, which can miss important water quality dynamics if parameterized inadequately, novel Internet-enabled sensor nodes are used to autonomously adapt their measurement frequency to real-time weather forecasts and hydrologic conditions. This dynamic approach has the potential to significantly improve the use of constrained experimental resources, such as automated grab samplers, which continue to provide a strong alternative to sampling water quality dynamics when in situ sensors are not available. Compared to conventional flow-weighted or time-weighted sampling schemes, which rely on preset thresholds, a major benefit of the approach is the ability to dynamically adapt to features of an underlying hydrologic signal. A 28 km2 urban watershed was studied to characterize concentrations of total suspended solids (TSS) and total phosphorus. Water quality samples were autonomously triggered in response to features in the underlying hydrograph and real-time weather forecasts. The study watershed did not exhibit a strong first flush and intraevent concentration variability was driven by flow acceleration, wherein the largest loadings of TSS and total phosphorus corresponded with the steepest rising limbs of the storm hydrograph. The scalability of the proposed method is discussed in the context of larger sensor network deployments, as well the potential to improving control of urban water quality.

  5. Measuring the Quality of Ecotourism Services

    Full Text Available Ecotourism forms the pillar of the country’s tourism industry. Ecotourists make up more than 10% of international tourists in Malaysia. When service quality is thought of as an important factor to the success of tourism service providers, the importance of estimating service quality provided to tourists becomes apparent. Estimating service quality provides tourism service providers with the necessary information needed to manage their marketing operations appropriately. Therefore, this estimation should be performed with the right measurement scales. Despite the high volume of research on service quality (SERVQUAL models in recent years, limited effort has been directed toward improving the tool for measuring service quality, particularly to apply to the ecotourism sector in developing countries. This article aims to improve a SERVQUAL model that is suitable for ecotourism areas in developing countries using five dimensions of the original model and one additional sustainability dimension. Based on a survey of 127 tourists in Tasik Kenyir, an exploratory factor analysis (EFA was conducted to discover the underlying dimension of ecotourism services and test for reliability and validity. Using EFA resulted in seven factors totaling 27 items. These factors are labeled as follows: tangible sustainability, sustainable practices, tangibility, reliability, responsiveness, assurance, and empathy. The results reveal that when SERVQUAL is applied within the ecotourism context, new dimensions of tangible sustainability and sustainable practices may emerge. The result implies the need to refine the SERVQUAL model when used in different contexts.

    2017-09-01

    An innovative optical method is introduced for the beam quality measurement of any arbitrary transverse mode based on the reconstruction of the mode from a few-frame image of the beam cross-section. This is performed by the decomposition of a mode to its basic Hermite-Gaussian modal coefficients. The performance of the proposed method is examined through M 2-factor measurement of the beam of a Nd:YAG laser which was forced to oscillate in a certain mode using a crossed rectangular intracavity aperture. Obtained results have shown that this method can be alternatively replaced for the hologram- and ISO-based techniques recently exploiting for beam quality measurement regardless of the mode type and the position of utilized CCD camera along the beam direction.

    1996-12-31

    Grid interferences caused by wind turbines (WT) are getting a severe problem in Germany with the fast increasing number of installed turbines. The wind energy capacity was doubled annually in the past three years. The actual situation and the plannings for the next years will lead to a situation, where high wind energy penetration will exercise a big influence on the power and voltage quality of local utility networks. Measurements performed in Germany according to a national guideline show a big variety in power quality performance of WT`s, which does affect the requirements for grid connection and thus the economical situation of wind energy projects to a large extent. The results from more than 25 power quality measurements will be discussed in this paper. 5 refs., 5 figs., 1 tab.

    The dosimetry of air and the tissue-equivalent phantom made of acryl are carried out by the tissue-equivalent proportional counter (TEPC) and TEPC with wall contained B, and both results were compared. The changes of quality with distance from the beam center are determined by the frequency mean renewal energy y F (y)and the dose mean renewal energy y D (y) as indicators of quality. Both y F (y)and y D (y) of tissue-equivalent phantom are larger than air, but very large change was not observed in all distance. The dose rate is determined by y D (y), the number of events and measurement time. Change of dose rate was larger than the change of quality. The maximum value of dose rate depended on γray and neutron beam showed at the point 2 cm away from the center. (S.Y.)

    2015-04-29

    Although sociodemographic factors are one aspect of understanding the effects of neighborhood environments on health, equating neighborhood quality with socioeconomic status ignores the important role of physical neighborhood attributes. Prior work on neighborhood environments and health has relied primarily on level of socioeconomic disadvantage as the indicator of neighborhood quality without attention to physical neighborhood quality. A small but increasing number of studies have assessed neighborhood physical characteristics. Findings generally indicate that there is an association between living in deprived neighborhoods and poor health outcomes, but rigorous evidence linking specific physical neighborhood attributes to particular health outcomes is lacking. This paper discusses the methodological challenges and limitations of measuring physical neighborhood environments relevant to health and concludes with proposed directions for future work.

  12. Accountability Quality Shuffler Measurements on Pits

    International Nuclear Information System (INIS)

    Rinard, P.M.

    2000-01-01

    Pits have generally been treated as accountable units that are intact if merely present and they are excluded from the more demanding nondestructive assay requirements. As pits begin to flow into disposition streams, there may be more incentive to measure the masses of their fissile components for accountability purposes. This Department of Energy Office of Safeguards and Security (OSS) Lifecycle Project has explored some ways in which such measurements may be done successfully. The active neutron instrument called a shuffler has been used to measure a variety of actual pits, and a calculational technique has been developed to accurately predict such count rates. Passive multiplicity counting has previously been applied to pits for determining their plutonium contents. This combination of measurement and calculational techniques provide powerful and accurate tools for determining the fissile contents of pits with the quality needed for accountability purposes

    Millard, A D

    2000-11-01

    The aim of the study was to develop and pilot a scale measuring the quality of audit projects through audit project reports. Statements about clinical audit projects were selected from existing instruments assessing the quality of clinical audit projects to form a Likert scale. Audit facilitators based in Scottish health boards and trusts piloted the scale. The participants were known to have over 2 years of experience of supporting clinical audit. The response at first test was 11 of 14 and at the second test 27 of 46. Audit facilitators tested the draft scale by expressing their strength of agreement or disagreement with each statement for three reports. Validity and reliability were assessed by test - re-test, item - total, and total - global indicator correlation. Of the 20 statements, 15 had satisfactory correlation with scale totals. Scale totals had good correlation with global indicators. Test re-test correlation was modest. The wide range of responses means further research is needed to measure the consistency of audit facilitators' interpretations, perhaps comparing a trained group with an untrained group. There may be a need for a separate scale for reaudits. Educational impact is distinct from project impact generally. It may be more meaningful to treat the selection of projects and aims, methodology and impact separately as subscales and take a project profiling approach rather than attempting to produce a global quality index.

    The authors conducted air quality measurements of the criteria pollutants carbon monoxide, nitrogen oxides, and ozone together with meteorological measurements at a park site southeast of College Station, TX, during the 2006 Texas Air Quality Study II (TexAQS). Ozone, a primary focus of the measurements, was above 80 ppb during 3 days and above 75 ppb during additional 8 days in summer 2006, suggestive of possible violations of the ozone National Ambient Air Quality Standard (NAAQS) in this area. In concordance with other air quality measurements during the TexAQS II, elevated ozone mixing ratios coincided with northerly flows during days after cold front passages. Ozone background during these days was as high as 80 ppb, whereas southerly air flows generally provided for an ozone background lower than 40 ppb. Back trajectory analysis shows that local ozone mixing ratios can also be strongly affected by the Houston urban pollution plume, leading to late afternoon ozone increases of as high as 50 ppb above background under favorable transport conditions. The trajectory analysis also shows that ozone background increases steadily the longer a southern air mass resides over Texas after entering from the Gulf of Mexico. In light of these and other TexAQS findings, it appears that ozone air quality is affected throughout east Texas by both long-range and regional ozone transport, and that improvements therefore will require at least a regionally oriented instead of the current locally oriented ozone precursor reduction policies.

    There is an increasing focus on the air quality in Norwegian cities and townships. The air quality depends on several factors and the connections are complex. The aim of this report is to present a short and simple survey of this complex field. The report consists of three parts: Part 1 is a survey of the development until today. Measurements of SO 2 and soot were started in the 1950's. Systematic determinations of NO x and NO 2 , CO and particles, ozone and benzene was started during the last three decades. The population exposure to air pollutants and their main sources are described as well as the air quality in Norwegian cities compared to other cities in Europe. In part 2 developments within transport, a sector necessary for understanding the development, are described. Part 3 is a survey of forecasting the air quality in Norway, pollution warnings and surveillance. The forecasts are based on assumed developments in important sectors such as transport, energy consumption for heating and industrial purposes and the effects of demands for fuel and vehicles. Effect analyses of further measures which may be useful for reaching the national goals for the air quality are carried out. A survey of the most important limiting values and criteria as well as technical terms is presented in the report and in the appendix. The report is commissioned by the Norwegian Petroleum Institute (Norsk Petroleumsinstitutt) and the Norwegian Road Federation (Opplysningsraadet for Veitrafikken)

  20. [Quality indicators for National Disease Management Guidelines using the example of the National Disease Management Guideline for "Chronic Heart Failure"].

    Science.gov (United States)

    Nothacker, Monika Judith; Langer, Thomas; Weinbrenner, Susanne

    2011-01-01

    Together with an expert committee a structured approach to determining quality indicators for National Disease Management Guidelines has been developed. The key steps of this approach include: introducing guideline authors to the methodology at an early stage of the process of guideline development, pre-selecting recommendations of the guideline which are potentially measurable by means of quality indicators, assessing the potentially measurable quality indicators in written form using five criteria (including their importance for the health care system and clarity of definitions) and approving them in a formal consensus process. For lack of a database these quality indicators must be regarded as preliminary. For the National Disease Management Guideline "Chronic Heart Failure" nine rate-based indicators have been chosen. The indicators correspond to important strong recommendations (grade of recommendation: A) from the fields of diagnosis (two), general therapeutic strategy (two), specific treatment (three), clinical monitoring (one) and co-ordination of care (one). In a second step, the quality indicators have to be validated within a pilot project. The determination and assessment of the potential quality indicators have revealed room for improvement of guideline development. In particular, there is a need for more health care data and for specification of recommendations.

  1. Quality assurance for radon measurements in Germany

    2005-01-01

    Full text: Radiation protection regarding work activities at workplaces with naturally occurring radiation has been regulated in the German Radiation Protection Ordinance. Regulations refer only to workplaces where the presence of natural radiation leads to a significant increase in the exposure of workers. These workplaces were identified in the following working areas with enhanced exposures to radon-222: underground mines, including visitor mines and show caves; radon-spas and galleries; water supply and distribution industries. Presently, regulations are being initiated by the German government to limit the exposures to radon in homes. For radon measurements at workplaces passive radon devices for individual monitoring as well as active measuring systems for workplace monitoring can be used. However, passive radon devices are preferred for radon measurements in homes because of low costs and availability in large quantities. To assure the quality of radon measurements the German Federal Office for Radiation Protection (BfS) has established annual interlaboratory comparisons for passive radon devices. The comparisons are carried out in the BfS radon calibration laboratory accredited by the German Calibration Service. Passive radon devices which use solid state track detectors, electrets or activated charcoal can be submitted. Approved radon services which offer radon measurements to determine radon exposure in homes and at workplaces have to pass the comparisons successfully. (author)

    Roth, Carmen [Hydrology of surface Waters, Bavarian Environment Agency, Hof (Germany)], E-mail: Carmen.Roth@lfu.bayern.de

    2008-11-01

    The hydrology of surface waters is based on the knowledge of the two main hydrological parameters, water level and discharge. These data are not only needed for almost every hydrological planning, but are very important for the management of high and low water. Our long term goal is a complete registration of every natural runoff - covering everything from low to high water - at our 600 measuring stations using limited resources but at the same time achieving high reliability and quality. To this point we are currently enforcing the use of modern data acquisition technology for water level and discharge measurements. The new techniques enable a continuous registration of water levels, actual velocity and consequently the discharge. Currently we are using gauging methods like the well known bubble gauge and radar, while the ultrasonic systems become more and more frequent. The moving boat techniques using the ultrasonic-Doppler-systems (e.g. ADCP, Q-Liner) are gradually substituting traditional methods for discharge measurement. In addition to that hydraulic methods (e. g. SIMK (registered) ) are being incorporated in the measuring systems as well. Since 2000 almost all gauges have been equipped with data loggers and automatic data transmission systems. One of the outcomes of these investments is the online availability of hydrological data on our website (www.hnd.bayern.de) where high quality data can be easily accessed. A new project has been initiated to improve the present rating curve. By means of hydraulic calculation the curve will be verified and if necessary adjusted to minimise deviations in the near future, which is of high importance especially for flooding forecasts.

  4. Video quality measure for mobile IPTV service

    Kim, Wonjun; Kim, Changick

    2008-08-01

    Mobile IPTV is a multimedia service based on wireless networks with interactivity and mobility. Under mobile IPTV scenarios, people can watch various contents whenever they want and even deliver their request to service providers through the network. However, the frequent change of the wireless channel bandwidth may hinder the quality of service. In this paper, we propose an objective video quality measure (VQM) for mobile IPTV services, which is focused on the jitter measurement. Jitter is the result of frame repetition during the delay and one of the most severe impairments in the video transmission via mobile channels. We first employ YUV color space to compute the duration and occurrences of jitter and the motion activity. Then the VQM is modeled by the combination of these three factors and the result of subjective assessment. Since the proposed VQM is based on no-reference (NR) model, it can be applied for real-time applications. Experimental results show that the proposed VQM highly correlates to subjective evaluation.

    The Nation's water resources are the basis for life and our economic vitality. These resources support a complex web of human activities and fishery and wildlife needs that depend upon clean water. Demands for good-quality water for drinking, recreation, farming, and industry are rising, and as a result, the American public is concerned about the condition and sustainability of our water resources. The American public is asking: Is it safe to swim in and drink water from our rivers or lakes? Can we eat the fish that come from them? Is our ground water polluted? Is water quality degrading with time, and if so, why? Has all the money we've spent to clean up our waters, done any good? The U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program was designed to provide information that will help answer these questions. NAWQA is designed to assess historical, current, and future water-quality conditions in representative river basins and aquifers nationwide. One of the primary objectives of the program is to describe relations between natural factors, human activities, and water-quality conditions and to define those factors that most affect water quality in different parts of the Nation. The linkage of water quality to environmental processes is of fundamental importance to water-resource managers, planners, and policy makers. It provides a strong and unbiased basis for better decisionmaking by those responsible for making decisions that affect our water resources, including the United States Congress, Federal, State, and local agencies, environmental groups, and industry. Information from the NAWQA Program also will be useful for guiding research, monitoring, and regulatory activities in cost effective ways.

  7. Measures of Image Quality. Chapter 4

    Energy Technology Data Exchange (ETDEWEB)

    Maidment, A. D.A. [University of Pennsylvania, Philadelphia (United States)

    2014-09-15

    A medical image is a pictorial representation of a measurement of an object or function of the body. This information can be acquired in one to three spatial dimensions. It can be static or dynamic, meaning that it can also be measured as a function of time. Certain fundamental properties can be associated with all of these data. Firstly, no image can exactly represent the object or function; at best, one has a measurement with an associated error equal to the difference between the true object and the measured image. Secondly, no two images will be identical, even if acquired with the same imaging system of the same anatomic region; this variability is generally referred to as noise. There are many different ways to acquire medical image data; the various mechanisms of acquisition are described in detail in the subsequent chapters. However, regardless of the method of image formation, one must be able to judge the fidelity of the image in an attempt to answer the question “How accurately does the image portray the body or the bodily function?” This judgement falls under the rubric of ‘image quality’. In this chapter, methods of quantifying image quality are described.

  8. Distributional Benefit Analysis of a National Air Quality Rule

    Full Text Available Under Executive Order 12898, the U.S. Environmental Protection Agency (EPA must perform environmental justice (EJ reviews of its rules and regulations. EJ analyses address the hypothesis that environmental disamenities are experienced disproportionately by poor and/or minority subgroups. Such analyses typically use communities as the unit of analysis. While community-based approaches make sense when considering where polluting sources locate, they are less appropriate for national air quality rules affecting many sources and pollutants that can travel thousands of miles. We compare exposures and health risks of EJ-identified individuals rather than communities to analyze EPA’s Heavy Duty Diesel (HDD rule as an example national air quality rule. Air pollutant exposures are estimated within grid cells by air quality models; all individuals in the same grid cell are assigned the same exposure. Using an inequality index, we find that inequality within racial/ethnic subgroups far outweighs inequality between them. We find, moreover, that the HDD rule leaves between-subgroup inequality essentially unchanged. Changes in health risks depend also on subgroups’ baseline incidence rates, which differ across subgroups. Thus, health risk reductions may not follow the same pattern as reductions in exposure. These results are likely representative of other national air quality rules as well.

    The authors conducted a study to validate the following 3 evidence-based, process-of-care quality measures focused on dental caries prevention for children with an elevated risk of experiencing caries: sealants for 6- to 9-year-olds, sealants for 10- to 14-year-olds, and topical fluoride. Using evidence-based guidelines, the Dental Quality Alliance developed measures for implementation with administrative data at the plan and program levels. To validate the measures, the authors used data from the Florida and Texas Medicaid programs and Children's Health Insurance Programs and from national commercial dental benefit plans. Data were extracted from 414 randomly selected dental office records to validate the use of administrative data to accurately calculate the measures. The authors also assessed statistically significant variations in overall measure performance. Agreement between administrative data and dental records was 95% for sealants (κ = 0.82) and 90% for topical fluoride (κ = 0.78). Sensitivity and specificity were 90.7% and 88.5% for topical fluoride and 77.8% and 98.8% for sealants, respectively. Variation in overall measure performance was greatest for topical fluoride (χ(2) = 5,887.1; P caries received at least 2 topical fluoride applications during the reporting year. Although there was greater variation in performance for sealants for 6- to 9-year-olds (range, 21.0-31.3%; χ(2) = 548.6; P caries prevention process-of-care quality measures can be implemented feasibly and validly using administrative claims data. The measures can be used to assess, monitor, and improve the proportion of children with an elevated risk of experiencing dental caries who receive evidence-based caries prevention services.

  11. Correction of stream quality trends for the effects of laboratory measurement bias

    Science.gov (United States)

    Alexander, Richard B.; Smith, Richard A.; Schwarz, Gregory E.

    1993-01-01

    We present a statistical model relating measurements of water quality to associated errors in laboratory methods. Estimation of the model allows us to correct trends in water quality for long-term and short-term variations in laboratory measurement errors. An illustration of the bias correction method for a large national set of stream water quality and quality assurance data shows that reductions in the bias of estimates of water quality trend slopes are achieved at the expense of increases in the variance of these estimates. Slight improvements occur in the precision of estimates of trend in bias by using correlative information on bias and water quality to estimate random variations in measurement bias. The results of this investigation stress the need for reliable, long-term quality assurance data and efficient statistical methods to assess the effects of measurement errors on the detection of water quality trends.

    2014-01-01

    We sought to explore the claims data-related issues relevant to quality measure development for Medicaid and the Children's Health Insurance Program (CHIP), illustrating the challenges encountered and solutions developed around 3 distinct performance measure topics: care coordination for children with complex needs, quality of care for high-prevalence conditions, and hospital readmissions. Each of 3 centers of excellence presents an example that illustrates the challenges of using claims data for quality measurement. Our Centers of Excellence in pediatric quality measurement used innovative methods to develop algorithms that use Medicaid claims data to identify children with complex needs; overcome some shortcomings of existing data for measuring quality of care for common conditions such as otitis media; and identify readmissions after hospitalizations for lower respiratory infections. Our experience constructing quality measure specifications using claims data suggests that it will be challenging to measure key quality of care constructs for Medicaid-insured children at a national level in a timely and consistent way. Without better data to underpin pediatric quality measurement, Medicaid and CHIP will have difficulty using some existing measures for accountability, value-based purchasing, and quality improvement both across states and within states.

    Garland, D.L.

    1980-01-01

    The basic Quality Assurance Program Requirements standard for the National Waste Terminal Storage Program has been developed primarily for nuclear reactors and other fairly well established nuclear facilities. In the case of waste isolation, however, there are many ongoing investigations for which quality assurance practices and requirements have not been well defined. This paper points out these problems which require supplementary requirements. Briefly these are: (1) the language barrier, that is geologists and scientists are not familiar with quality assurance (QA) terminology; (2) earth sciences deal with materials that cannot be characterized as easily as metals or other materials that are reasonably homogeneous; (3) development and control of mathematical models and associated computer programs; (4) research and development

  19. How to Improve the Quality of Screening Endoscopy in Korea: National Endoscopy Quality Improvement Program.

    2016-07-01

    In Korea, gastric cancer screening, either esophagogastroduodenoscopy or upper gastrointestinal series (UGIS), is performed biennially for adults aged 40 years or older. Screening endoscopy has been shown to be associated with localized cancer detection and better than UGIS. However, the diagnostic sensitivity of detecting cancer is not satisfactory. The National Endoscopy Quality Improvement (QI) program was initiated in 2009 to enhance the quality of medical institutions and improve the effectiveness of the National Cancer Screening Program (NCSP). The Korean Society of Gastrointestinal Endoscopy developed quality standards through a broad systematic review of other endoscopic quality guidelines and discussions with experts. The standards comprise five domains: qualifications of endoscopists, endoscopic unit facilities and equipment, endoscopic procedure, endoscopy outcomes, and endoscopic reprocessing. After 5 years of the QI program, feedback surveys showed that the perception of QI and endoscopic practice improved substantially in all domains of quality, but the quality standards need to be revised. How to avoid missing cancer in endoscopic procedures in daily practice was reviewed, which can be applied to the mass screening endoscopy. To improve the quality and effectiveness of NCSP, key performance indicators, acceptable quality standards, regular audit, and appropriate reimbursement are necessary.

    Service quality and patient satisfaction are essential to health care organization success. Parasuraman, Zeithaml, and Berry introduced SERVQUAL, a prominent service quality measure not yet applied to urgent care. We develop an instrument to measure perceived service quality and identify the determinants of patient satisfaction/ behavioral intentions. We examine the relationships among perceived service quality, patient satisfaction and behavioral intentions, and demonstrate that urgent care service quality is not equivalent using measures of perceptions only, differences of expectations minus perceptions, ratio of perceptions to expectations, and the log of the ratio. Perceptions provide the best measure of urgent care service quality.

  1. Signal quality measures for unsupervised blood pressure measurement

    Abdul Sukor, J; Redmond, S J; Lovell, N H; Chan, G S H

    2012-01-01

    Accurate systolic and diastolic pressure estimation, using automated blood pressure measurement, is difficult to achieve when the transduced signals are contaminated with noise or interference, such as movement artifact. This study presents an algorithm for automated signal quality assessment in blood pressure measurement by determining the feasibility of accurately detecting systolic and diastolic pressures when corrupted with various levels of movement artifact. The performance of the proposed algorithm is compared to a manually annotated reference scoring (RS). Based on visual representations and audible playback of Korotkoff sounds, the creation of the RS involved two experts identifying sections of the recorded sounds and annotating sections of noise contamination. The experts determined the systolic and diastolic pressure in 100 recorded Korotkoff sound recordings, using a simultaneous electrocardiograph as a reference signal. The recorded Korotkoff sounds were acquired from 25 healthy subjects (16 men and 9 women) with a total of four measurements per subject. Two of these measurements contained purposely induced noise artifact caused by subject movement. Morphological changes in the cuff pressure signal and the width of the Korotkoff pulse were extracted features which were believed to be correlated with the noise presence in the recorded Korotkoff sounds. Verification of reliable Korotkoff pulses was also performed using extracted features from the oscillometric waveform as recorded from the inflatable cuff. The time between an identified noise section and a verified Korotkoff pulse was the key feature used to determine the validity of possible systolic and diastolic pressures in noise contaminated Korotkoff sounds. The performance of the algorithm was assessed based on the ability to: verify if a signal was contaminated with any noise; the accuracy, sensitivity and specificity of this noise classification, and the systolic and diastolic pressure

    1985-01-01

    1 - Description of problem or function: The Safeguards Analytical Laboratory Evaluation (SALE) program is a statistical analysis program written to analyze the data received from laboratories participating in the SALE quality control and evaluation program. The system is aimed at identifying and reducing analytical chemical measurement errors. Samples of well-characterized materials are distributed to laboratory participants at periodic intervals for determination of uranium or plutonium concentration and isotopic distributions. The results of these determinations are statistically evaluated and participants are informed of the accuracy and precision of their results. 2 - Method of solution: Various statistical techniques produce the SALE output. Assuming an unbalanced nested design, an analysis of variance is performed, resulting in a test of significance for time and analyst effects. A trend test is performed. Both within- laboratory and between-laboratory standard deviations are calculated. 3 - Restrictions on the complexity of the problem: Up to 1500 pieces of data for each nuclear material sampled by a maximum of 75 laboratories may be analyzed

    Kenneth W. Kizer, MD MPH, is president and chief executive officer (CEO) of the National Forum for Health Care Quality Measurement and Reporting (National Quality Forum [NQF]), a not-for-profit membership organization created to develop and implement a national strategy for measuring and reporting healthcare quality. Dr. Kizer previously served as Under Secretary for Health in the U.S. Department of Veterans Affairs (VA) and is widely credited as being the chief architect of and driving force behind the greatest transformation of VA healthcare since its creation in 1946. NQF is a public-private partnership designed to involve all segments of the nation's healthcare system. The organization was proposed as part of the findings of the President's Advisory Commission on Consumer Protection and Quality in the Health Care Industry (1998). Since the release of those findings, leaders from consumer, purchaser, provider, health plan, and health services research organizations, as well as from government, have met to define the mission, structure, and financing of NQF, and staff support has been provided by the United Hospital Fund of New York. NQF is primarily a membership dues- and grant-financed organization and has received significant public and private funding from foundation and corporate grants, including a $2.5-million founding grant from the Robert-Wood Johnson Foundation and a $1-million founding grant from the California Healthcare Foundation. NQF also received initial financial support from The Commonwealth Fund and United Hospital Fund.

    each gap, we searched for available measures not already being used in programs. Where existing measures did not cover gaps, we recommended refinements to existing measures or proposed measures for development. We shared the results of the measure gap analysis with a roundtable of national experts in cancer care and oncology measurement. During a web meeting and an in-person meeting, the roundtable reviewed the gap analysis and identified priority opportunities for improving measurement. The group determined that overreliance on condition-specific process measures is problematic because of rapidly changing evidence and increasing personalization of cancer care. The group's primary recommendation for enhancing measure sets was to prioritize and develop effective cross-cutting measures that assess clinical and patient-reported outcomes, including shared decision making, care planning, and symptom control. The group also prioritized certain safety and structural measures to complement condition-specific process measures. Further, the group explored strategies for using clinical pathways and devising layered measurement approaches to improve measurement for accountable care. This article presents the roundtable's conclusions and recommendations for next steps. Funding for this project was provided by the National Pharmaceutical Council (NPC).

    In 2013, the Royal Dutch Society for Physical Therapy launched the program "Quality in Motion." This program aims to collect data from electronic health record systems in a registry that is fed back to physical therapists, facilitating quality improvement. The purpose of this study was to describe the development of an implementation strategy for the program and to evaluate the feasibility of building a registry and implementing patient-reported outcome measures (PROMs) in physical therapist practices. A stepwise approach using mixed methods was established in 3 consecutive pilots with 355 physical therapists from 66 practices. Interim results were evaluated using quantitative data from a self-assessment questionnaire and the registry and qualitative data from 21 semistructured interviews with physical therapists. Descriptive statistics and McNemar's symmetry chi-squared test were used to summarize the feasibility of implementing PROMs. PROMs were selected for the 5 most prevalent musculoskeletal conditions in Dutch physical therapist practices. A core component of the implementation strategy was the introduction of knowledge brokers to support physical therapists in establishing the routine use of PROMs in clinical practice and to assist in executing peer assessment workshops. In February 2013, 30.3% of the physical therapist practices delivered 4.4 completed treatment episodes per physical therapist to the registry; this increased to 92.4% in November 2014, delivering 54.1 completed patient episodes per physical therapist. Pre- and posttreatment PROM use increased from 12.2% to 39.5%. It is unclear if the participating physical therapists reflect a representative sample of Dutch therapists. Building a registry and implementing PROMs in physical therapist practices are feasible. The routine use of PROMs needs to increase to ensure valid feedback of outcomes. Using knowledge brokers is promising for implementing the program via peer assessment workshops. © 2017

    Riks-Stroke, the Swedish Stroke Register, is the world's longest-running national stroke quality register (established in 1994) and includes all 76 hospitals in Sweden admitting acute stroke patients. The development and maintenance of this sustainable national register is described. Riks-Stroke includes information on the quality of care during the acute phase, rehabilitation and secondary prevention of stroke, as well as data on community support. Riks-Stroke is unique among stroke quality registers in that patients are followed during the first year after stroke. The data collected describe processes, and medical and patient-reported outcome measurements. The register embraces most of the dimensions of health-care quality (evidence-based, safe, provided in time, distributed fairly and patient oriented). Annually, approximately 25,000 patients are included. In 2009, approximately 320,000 patients had been accumulated (mean age 76-years). The register is estimated to cover 82% of all stroke patients treated in Swedish hospitals. Among critical issues when building a national stroke quality register, the delicate balance between simplicity and comprehensiveness is emphasised. Future developments include direct transfer of data from digital medical records to Riks-Stroke and comprehensive strategies to use the information collected to rapidly implement new evidence-based techniques and to eliminate outdated methods in stroke care. It is possible to establish a sustainable quality register for stroke at the national level covering all hospitals admitting acute stroke patients. Riks-Stroke is fulfilling its main goals to support continuous quality improvement of Swedish stroke services and serve as an instrument for following up national stroke guidelines. © 2010 The Authors.

    Core components Health care-associated infections (HAIs) are a major cause of morbidity and mortality. In addition to pain and suffering, HAIs increase the cost of health care and generates indirect costs from loss of productivity for patients and society as a whole. Since 2005, the Pan American Health Organization has provided support to countries for the assessment of their capacities in infection prevention and control (IPC). More than 130 hospitals in 18 countries were found to have poor IPC programmes. However, in the midst of many competing health priorities, IPC programmes are not high on the agenda of ministries of health, and the sustainability of national programmes is not viewed as a key point in making health care systems more consistent and trustworthy. Comprehensive IPC programmes will enable countries to reduce the mobility, mortality and cost of HAIs and improve quality of care. This paper addresses the relevance of national infection prevention and control (NIPC) programmes in promoting, supporting and reinforcing IPC interventions at the level of hospitals. A strong commitment from national health authorities in support of national IPC programmes is crucial to obtaining a steady decrease of HAIs, lowering health costs due to HAIs and ensuring safer care.

    The Office of Radiation and Indoor Air, U.S. Environmental Protection Agency (EPA), operates six radon exposure chambers in its two laboratories, the National Air and Radiation Environmental Laboratory (NAREL) in Montgomery, Alabama, and the Las Vegas Facility, Las Vegas, Nevada. These radon exposure chambers are used to calibrate and test portable radon measuring instruments, test commercial suppliers of radon measurement services through the Radon Measurement Proficiency Program, and expose passive measurement devices to known radon concentrations as part of a quality assurance plan for federal and state studies measuring indoor radon concentrations. Both laboratories participate in national and international intercomparisons for the measurement of radon and are presently working with the National Institute of Standards and Technology (NIST) to receive a certificate of traceability for radon measurements. NAREL has developed an estimate of the total error in its calibration of each chamber`s continuous monitors as part of an internal quality assurance program. This paper discusses the continuous monitors and their calibration for the three chambers located in Montgomery, Alabama, as well as the results of the authors intercomparisons and total error analysis.

    To execute a complex business task, business entities may need to collaborate with each other as individually they may not have the capability or willingness to perform the task on its own. Such collaboration can be seen implemented in digital business ecosystems in the form of simple coalitions using multi-agent systems or by employing Electronic Institutions. A major challenge is choosing optimal partners who will deliver the agreed commitments, and act in the coalition’s interest. Business entities are scaled according to their quality level. Determining the quality of previously unknown business entities and predicting the quality of such an entity in a dynamic environment are crucial issues in Business Ecosystems. A comprehensive quality management system grounded in the concepts of Trust and Reputation can help address these issues.

    Adverse event (AE) rates in outpatient surgery are inconsistently reported, partly because of the lack of a standard definition of outpatient surgery. We compared the types and rates of surgical procedures defined by two national healthcare agencies: Health Care Cost Institute (HCCI) and the Healthcare Cost and Utilization Project (HCUP) and considered implications for quality measurement. We used HCCI and HCUP definitions to identify FY2012-14 VA outpatient surgeries. There were six times as many HCCI surgeries as HCUP (6,575,830 versus 1,086,640). Ninety-nine percent of HCUP-defined surgeries were also identified by HCCI. More HCUP surgeries had higher average Medicare Relative Value Units then HCCI surgeries [5.3 (SD = 4.4) versus 1.6 (SD = 2.3) RVUs]. Rates and types of procedures vary widely between definitions. Quality measurement using HCCI versus HCUP may produce significantly lower AE rates because many of the surgeries included reflect low complexity and potentially low risk of AEs.

    The objective of this study was to estimate Canadian national milk quality parameters and estimate the bulk tank milk (BTM) prevalence of 4 mastitis pathogens, Staphylococcus aureus, Streptococcus agalactiae, Mycoplasma bovis, and Prototheca spp., on Canadian dairy farms. A questionnaire was sent to all Canadian dairy producers. Of the 1,062 producers who completed the questionnaire, 374 producers from across the country were visited and milking hygiene was assessed. Farm-level milk quality data for all Canadian dairy producers was collected from the provincial marketing boards and combined with the questionnaire and farm visit data. In addition, a BTM sample was collected either during the farm visit or by the marketing board in November of 2015 and was tested for 4 major mastitis pathogens using the PathoProof Mastitis Major 4 PCR Assay (Thermo Fisher Scientific Inc., Waltham, MA). Apparent herd-level prevalence was 46% for S. aureus, 6% for Prototheca spp., 0% for M. bovis, and 0% for Strep. agalactiae. Due to the low prevalence of M. bovis and Strep. agalactiae and a lack of significant factors associated with farms testing positive for Prototheca spp., an association analysis could only be carried out for Staph. aureus-positive farms. Factors associated with Staph. aureus-positive farms were not fore-stripping cows before milking (odds ratio = 1.87), milking with a pipeline system (odds ratio = 2.21), and stall bases made of a rubberized surface (mats and mattresses), whereas protective factors were using blanket dry cow therapy (odds ratio = 0.49) and applying a tag or visible mark on cows known to have chronic mastitis infections (odds ratio = 0.45). The Canadian national production-weighted geometric mean somatic cell count was determined to be 208,000 cells/mL. This is the first national dairy study conducted in Canada. Participating farms had higher milk yield; were more likely to have a loose housing system, parlor, or automated milking system; and had

    2011-01-01

    Purpose: The increasing frequency of computerized tomography (CT) examinations is well documented, leading to concern about potential radiation risks for patients. However, the consequences of not performing the CT examination and missing injuries and disease are potentially serious, impacting upon correct patient management. The ALARA principle of dose optimization must be employed for all justified CT examinations. Dose indicators displayed on the CT console as either CT dose index (CTDI) and/or dose length product (DLP), are used to indicate dose and can quantify improvements achieved through optimization. Key scan parameters contributing to dose have been identified in previous literature and in previous work by our group. The aim of this study was to optimize the scan parameters of mA; kV and pitch, whilst maintaining image quality and reducing dose. This research was conducted using psychophysical image quality measurements on a CT quality assurance (QA) phantom establishing the impact of dose optimization on image quality parameters. Method: Current CT scan parameters for head (posterior fossa and cerebrum), abdomen and chest examinations were collected from 57% of CT suites available nationally in Malta (n = 4). Current scan protocols were used to image a Catphan 600 CT QA phantom whereby image quality was assessed. Each scan parameter: mA; kV and pitch were systematically reduced until the contrast resolution (CR), spatial resolution (SR) and noise were significantly lowered. The Catphan 600 images, produced by the range of protocols, were evaluated by 2 expert observers assessing CR, SR and noise. The protocol considered as the optimization threshold was just above the setting that resulted in a significant reduction in CR and noise but not affecting SR at the 95% confidence interval. Results: The limit of optimization threshold was determined for each CT suite. Employing optimized parameters, CTDI and DLP were both significantly reduced (p ≤ 0.001) by

    2017-11-01

    To investigate the use of data from national quality registries (NQRs) in local quality improvement as well as purported key factors for effective clinical use in Sweden. Comparative descriptive: a web survey of all Swedish hospitals participating in three NQRs with different levels of development (certification level). Heads of the clinics and physician(s) at clinics participating in the Swedish Stroke Register (Riksstroke), the Swedish National Registry of Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (GallRiks) and the Swedish Lung Cancer Registry (NLCR). Individual and unit level use of NQRs in local quality improvement, and perceptions on data quality, organizational conditions and user motivation. Riksstroke data were reported as most extensively used at individual and unit levels (x̅ 17.97 of 24 and x̅ 27.06 of 35). Data quality and usefulness was considered high for the two most developed NQRs (x̅ 19.86 for Riksstroke and x̅ 19.89 for GallRiks of 25). Organizational conditions were estimated at the same level for Riksstroke and GallRiks (x̅ 12.90 and x̅ 13.28 of 20) while the least developed registry, the NLCR, had lower estimates (x̅ 10.32). In Riksstroke, the managers requested registry data more often (x̅ 15.17 of 20). While there were significant differences between registries in key factors such as management interest, use of NQR data in local quality improvement seems rather prevalent, at least for Riksstroke. The link between the registry's level of development and factors important for routinization of innovations such as NQRs needs investigation. © The Author 2017.

    1992-01-01

    A national comparison on volume sample activity measurements methods may be regarded as a step toward accomplishing the traceability of the environmental and food chain activity measurements to national standards. For this purpose, the Radionuclide Metrology Laboratory has distributed 137 Cs and 134 Cs water-equivalent solid standard sources to 24 laboratories having responsibilities in this matter. Every laboratory has to measure the activity of the received source(s) by using its own standards, equipment and methods and report the obtained results to the organizer. The 'measured activities' will be compared with the 'true activities'. A final report will be issued, which plans to evaluate the national level of precision of such measurements and give some suggestions for improvement. (Author)

    2017-10-01

    A bilateral comparison in moisture measurement between the National Institute of Metrology Thailand (NIMT) and the Central Bureau of Weights and Measures (CBWM) was organized for quality assuring of rice and paddy moisture measurement in Thailand. The bilateral comparison was conducted by using the same batch of sample and moisture meter as transfer device. It consisted of two parts: moisture measurement in rice and in paddy. A rice moisture meter belonging to CBWM and rice standards prepared at the nominal moisture content of 10 %, 12 %, 14 % and 16 % at NIMT, were used for rice moisture comparison, while a paddy moisture meter belonging to NIMT and paddy standards prepared at the nominal moisture content of 12 %, 14 %, 16 % and 18 % at CBWM, were used for paddy moisture comparison. Both laboratories measured the moisture content of a sample by using the standard method in ISO 712 and used that sample to calibrate a moisture meter by means of the method based on ISO 7700-1. Since the moisture content of the sample can change during the comparison, correction values in moisture content between the standard value and the reading value from the moisture meter are used as calibration results for the comparison evaluation. For the rice moisture comparison, differences in the correction value measured by the two laboratories vary from 0.18 % to 0.46 %, with their combined comparison uncertainty of 0.37 % (k= 2). The main contribution to the difference comes from the standard values from both laboratories differing from 0.27 % to 0.53 %, as the rice standard was found to drift in moisture content less than 0.05 %. Similarly to the rice moisture comparison, differences in the correction value for the paddy moisture measurement range from 0.08 % to 0.56 % with the combined comparison uncertainty of 0.38 % (k = 2), whereas the stability in moisture content of the paddy sample at NIMT was found to be within 0.12 %.

    The American Academy of Sleep Medicine (AASM) commissioned five Workgroups to develop quality measures to optimize management and care for patients with common sleep disorders including insomnia. Following the AASM process for quality measure development, this document describes measurement methods for two desirable outcomes of therapy, improving sleep quality or satisfaction, and improving daytime function, and for four processes important to achieving these goals. To achieve the outcome of improving sleep quality or satisfaction, pre- and post-treatment assessment of sleep quality or satisfaction and providing an evidence-based treatment are recommended. To realize the outcome of improving daytime functioning, pre- and post-treatment assessment of daytime functioning, provision of an evidence-based treatment, and assessment of treatment-related side effects are recommended. All insomnia measures described in this report were developed by the Insomnia Quality Measures Workgroup and approved by the AASM Quality Measures Task Force and the AASM Board of Directors. The AASM recommends the use of these measures as part of quality improvement programs that will enhance the ability to improve care for patients with insomnia.

    The paper presents the progress registered by the Radionuclide Metrology Laboratory (RML) from IFIN-HH, in improvement of the quality of radiopharmaceuticals activity measurement, and assurance of the whole traceability chain from international level to the national users. The progress in organization of comparisons for radiopharmaceuticals activity measurement is analyzed. A detailed description of two recent national comparisons, and an international one, regarding 131 I solutions, within the frame of the IAEA's CRP E2.10.05 'Harmonization of quality practices for nuclear medicine radioactivity measurements' is done, with the analysis of the strong and week points in measurements. The most important outcome of the paper is the analysis of the evolution in quality of comparisons since a previously reported one. At the RML level, the improvements are: demonstration of the international equivalence of primary Romanian activity standard, improvement of the secondary standard, relevance of the comparison within the IAEA frame, implementation of a quality system in standardization and in comparisons, and implication of the RML in calibrations and metrological checks. The participants' reported improvements refer to growing of the awareness in quality of measurement and improvement of the measurement equipment. Reasons for future comparisons organization are presented. (author)

    2015-01-01

    Full Text Available Background. Data on potential variations in delivery of appropriate stroke care over time are scarce. We investigated temporal changes in the quality of acute hospital stroke care across five national audits in Europe over a period of six years. Methods. Data were derived from national stroke audits in Germany, Poland, Scotland, Sweden, and England/Wales/Northern Ireland participating within the European Implementation Score (EIS collaboration. Temporal changes in predefined quality indicators with comparable information between the audits were investigated. Multivariable logistic regression analyses were performed to estimate adherence to quality indicators over time. Results. Between 2004 and 2009, individual data from 542,112 patients treated in 538 centers participating continuously over the study period were included. In most audits, the proportions of patients who were treated on a SU, were screened for dysphagia, and received thrombolytic treatment increased over time and ranged from 2-fold to almost 4-fold increase in patients receiving thrombolytic therapy in 2009 compared to 2004. Conclusions. A general trend towards a better quality of stroke care defined by standardized quality indicators was observed over time. The association between introducing a specific measure and higher adherence over time might indicate that monitoring of stroke care performance contributes to improving quality of care.

This article compares regional performance for three measures that focus on transitions in care, and the care of patients with multiple conditions. Admissions for people with ambulatory care-sensitive conditions, hospital readmissions within 30 days of discharge, and compliance with practice guidelines for people with three chronic conditions (congestive heart failure, chronic obstructive pulmonary disease, and diabetes were analyzed using data drawn from the Centers for Medicare & Medicaid Services’ Standard Analytic Files for 5% of a 2004 national sample of Medicare beneficiaries which was divided by hospital referral regions and regional performance. There were significant regional differences in performance which we hypothesize could be improved through better care coordination and system management.Keywords: performance, quality, chronic condition, ambulatory care, sensitive conditions, readmissions

  1. Fourier transform based scalable image quality measure.

    Narwaria, Manish; Lin, Weisi; McLoughlin, Ian; Emmanuel, Sabu; Chia, Liang-Tien

    2012-08-01

    We present a new image quality assessment (IQA) algorithm based on the phase and magnitude of the 2D (twodimensional) Discrete Fourier Transform (DFT). The basic idea is to compare the phase and magnitude of the reference and distorted images to compute the quality score. However, it is well known that the Human Visual Systems (HVSs) sensitivity to different frequency components is not the same. We accommodate this fact via a simple yet effective strategy of nonuniform binning of the frequency components. This process also leads to reduced space representation of the image thereby enabling the reduced-reference (RR) prospects of the proposed scheme. We employ linear regression to integrate the effects of the changes in phase and magnitude. In this way, the required weights are determined via proper training and hence more convincing and effective. Lastly, using the fact that phase usually conveys more information than magnitude, we use only the phase for RR quality assessment. This provides the crucial advantage of further reduction in the required amount of reference image information. The proposed method is therefore further scalable for RR scenarios. We report extensive experimental results using a total of 9 publicly available databases: 7 image (with a total of 3832 distorted images with diverse distortions) and 2 video databases (totally 228 distorted videos). These show that the proposed method is overall better than several of the existing fullreference (FR) algorithms and two RR algorithms. Additionally, there is a graceful degradation in prediction performance as the amount of reference image information is reduced thereby confirming its scalability prospects. To enable comparisons and future study, a Matlab implementation of the proposed algorithm is available at http://www.ntu.edu.sg/home/wslin/reduced_phase.rar.

  2. Innovating for quality and value: Utilizing national quality improvement programs to identify opportunities for responsible surgical innovation.

    Woo, Russell K; Skarsgard, Erik D

    2015-06-01

    Innovation in surgical techniques, technology, and care processes are essential for improving the care and outcomes of surgical patients, including children. The time and cost associated with surgical innovation can be significant, and unless it leads to improvements in outcome at equivalent or lower costs, it adds little or no value from the perspective of the patients, and decreases the overall resources available to our already financially constrained healthcare system. The emergence of a safety and quality mandate in surgery, and the development of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) allow needs-based surgical care innovation which leads to value-based improvement in care. In addition to general and procedure-specific clinical outcomes, surgeons should consider the measurement of quality from the patients' perspective. To this end, the integration of validated Patient Reported Outcome Measures (PROMs) into actionable, benchmarked institutional outcomes reporting has the potential to facilitate quality improvement in process, treatment and technology that optimizes value for our patients and health system.

    2018-02-28

    BackgroundAs part of its mission, the U.S. Geological Survey (USGS) collects data to assess the quality of our Nation’s water resources. A high degree of reliability and standardization of these data are paramount to fulfilling this mission. Documentation of nationally accepted methods used by USGS personnel serves to maintain consistency and technical quality in data-collection activities. “The National Field Manual for the Collection of Water-Quality Data” (NFM) provides documented guidelines and protocols for USGS field personnel who collect water-quality data. The NFM provides detailed, comprehensive, and citable procedures for monitoring the quality of surface water and groundwater. Topics in the NFM include (1) methods and protocols for sampling water resources, (2) methods for processing samples for analysis of water quality, (3) methods for measuring field parameters, and (4) specialized procedures, such as sampling water for low levels of mercury and organic wastewater chemicals, measuring biological indicators, and sampling bottom sediment for chemistry. Personnel who collect water-quality data for national USGS programs and projects, including projects supported by USGS cooperative programs, are mandated to use protocols provided in the NFM per USGS Office of Water Quality Technical Memorandum 2002.13. Formal training, for example, as provided in the USGS class, “Field Water-Quality Methods for Groundwater and Surface Water,” and field apprenticeships supplement the guidance provided in the NFM and ensure that the data collected are high quality, accurate, and scientifically defensible.

    Full Text Available National health insurance is one of the government programs to facilitate health services for the people. The purpose of this research to determine whether there are effects of National Health Insurance program (JKN on profitability and service quality at Juanda Kuningan Hospital, of West Java. The method using the paired-t-test to analyze the difference between before and after the National Health Insurance program. The result showed that there is a difference in profitability and service quality between pre and post the implementation of national health insurance program. Gross profit margin measured the profitability, net profit margin, return on total assets, and return on equity. This result means that the value of the company's profitability is better when the program JKN yet takes place in the Juanda hospital. While on the service quality variable it is found that the mean value is higher when the JKN program has conducted at the hospital.DOI: 10.15408/etk.v17i1.7064

  12. Measuring environmental quality. An index of pollution

    International Nuclear Information System (INIS)

    Khanna, N.

    2000-01-01

    This paper develops an index of pollution based on the epidemiological dose-response function associated with each pollutant, and the welfare losses due to exposure to pollution. The probability of damage is translated into welfare losses, which provides the common metric required for aggregation. Isopollution surfaces may then be used to compare environmental quality over time and space. An Air Pollution Index (API) is computed using 1997 data for the criteria pollutants under the Clean Air Act (CAA). The results are compared with the EPA's Pollutant Standards Index (PSI). Two significant differences emerge: unlike the PSI, the API facilitates a detailed ranking of regions by air quality and API values may contradict PSI results. Some regions with PSI values of 100-200 are considered less polluted under the proposed methodology than those with PSI values between 50 and 100. The key reason for the difference is that PSI values are determined entirely by the gas with the highest relative concentration whereas the API value is based on the ambient concentrations of all pollutants. 14 refs

    2009-05-26

    Deming quality methodologies applied to safety are recognized with the National Safety Council's annual Robert W. Campbell Award. Over the last ten years, the implementation of Statistical Process Control and quality methodologies at the U.S. Department of Energy's Hanford Site have contributed to improved safety. Improvements attributed to Statistical Process Control are evidenced in Occupational Safety and Health records and documented through several articles in Quality Progress and the American Society of Safety Engineers publication, Professional Safety. Statistical trending of safety, quality, and occurrence data continues to playa key role in improving safety and quality at what has been called the world's largest environmental cleanup project. DOE's Hanford Site played a pivotal role in the nation's defense beginning in the 1940s, when it was established as part of the Manhattan Project. After more than 50 years of producing material for nuclear weapons, Hanford, which covers 586 square miles in southeastern Washington state, is now focused on three outcomes: (1) Restoring the Columbia River corridor for multiple uses; (2) Transitioning the central plateau to support long-term waste management; and (3) Putting DOE assets to work for the future. The current environmental cleanup mission faces challenges of overlapping technical, political, regulatory, environmental, and cultural interests. From Oct. 1, 1996 through Sept. 30, 2008, Fluor Hanford was a prime contractor to the Department of Energy's Richland Operations Office. In this role, Fluor Hanford managed several major cleanup activities that included dismantling former nuclear-processing facilities, cleaning up the Site's contaminated groundwater, retrieving and processing transuranic waste for shipment and disposal off-site, maintaining the Site's infrastructure, providing security and fire protection, and operating the Volpentest HAMMER Training and Education

    Patient-reported outcome measures (PROMs) are objective metrics critical to evaluating outcomes throughout orthopedic surgery. New instruments continue to emerge, increasing the breadth of information required for those intending to use these measures for research or clinical care. Although earlier metrics were developed using the principles of classic test theory, newer instruments constructed using item response theory are amenable to computer-adaptive testing and may change the way these instruments are administered. This article aims to define the psychometric properties that are important to understand when using all PROMs and to review the most widely used instruments in sports medicine.

  1. Comparing farmer and measured assessments of soil quality in Tanzania: Do they align?

    Directory of Open Access Journals (Sweden)

    Allison C. Kelly

    2016-06-01

    Full Text Available Background: There is a wide gap between actual and potential yields for many crops in Sub-Saharan Africa (SSA. Experts identify poor soil quality as a primary constraint to increased agricultural productivity. Therefore, increasing agricultural productivity by improving soil quality is seen as a viable strategy to enhance food security. Yet adoption rates of programs focused on improving soil quality have generally been lower than expected [1], [2]. Results: We explore a seldom considered factor that may limit farmers’ demand for improved soil quality, namely, whether the farmers’ self-assessment of their soil quality match the assessments of soil scientists. In this paper, using data from the Tanzania National Panel Survey (TZNPS, part of the Living Standards Measurement Study – Integrated Surveys on Agriculture (LSMS-ISA, we compare farmers’ own assessments of soil quality with scientific measurements of soil quality from the Harmonized World Soil Database (HWSD. The study found a considerable “mismatch” and most notably, that 11.5 percent of survey households that reported having “good” soil quality are measured by scientific standards to have severely limited nutrient availability. Conclusion: Mismatches between scientific measurements and farmer assessments of soil quality may highlight a potential barrier for programs seeking to encourage farmers to adopt soil quality improvement activities.

    A retail audit of lamb loin tenderness was conducted over a 12-month period to determine the variation in tenderness of Australian lamb. Tenderness was objectively measured using Warner-Bratzler (WB) shear force. Muscle pH and cooking loss were determined on all samples and colour was measured on a sub-sample of loins. A total of 909 midloins from retail butcher shops and supermarkets located in four Australian capital cities (Sydney, Canberra, Melbourne, and Perth) were evaluated at four sampling times (December 1997 and March, June, and October 1998). Overall, 20.3% of all midloins purchased had a WB shear force value above the threshold level of 5 kg. Generic samples from Melbourne butcher shops were similar for WB shear force on average to the generic samples from Canberra and Sydney, whereas those from Melbourne supermarkets had significantly (Plamb had a greater WB shear force (Plamb. No relationship was found between price per kg and shear force (r=0.02) for loins purchased in Sydney (n=220). Price per kg differed between months (Plamb sold in the domestic market. A lamb eating quality assurance system, based on set protocols, is one approach that is currently being investigated in Australia to ensure the supply of consistently high eating quality lamb to consumers.

  3. Conceptualizing and Measuring the Quality of Democracy: The Citizens’ Perspective

    2018-03-01

    Full Text Available In recent years, several measurements of the quality of democracy have been developed (e.g. Democracy Barometer, Varieties of Democracy Project. These objective measurements focus on institutional and procedural characteristics of democracy. This article starts from the premise that in order to fully understand the quality of democracy such objective measurements have to be complemented by subjective measurements based on the perspective of citizens. The aim of the article is to conceptualize and measure the subjective quality of democracy. First, a conceptualization of the subjective quality of democracy is developed consisting of citizens’ support for three normative models of democracy (electoral, liberal, and direct democracy. Second, based on the World Values Survey 2005–2007, an instrument measuring these different dimensions of the subjective quality of democracy is suggested. Third, distributions for different models of democracy are presented for some European and non-European liberal democracies. They reveal significant differences regarding the subjective quality of democracies. Fourth, the subjective quality of democracy of these countries is compared with the objective quality of democracy based on three indices (electoral democracy, liberal democracy and direct popular vote developed by the Varieties of Democracy (V-Dem Project. Finally, further research questions are discussed.

    1988-01-01

    This report is concerned with the application of software quality and evaluation measures to AI software and, more broadly, with the question of quality assurance for AI software. Considered are not only the metrics that attempt to measure some aspect of software quality, but also the methodologies and techniques (such as systematic testing) that attempt to improve some dimension of quality, without necessarily quantifying the extent of the improvement. The report is divided into three parts Part 1 reviews existing software quality measures, i.e., those that have been developed for, and applied to, conventional software. Part 2 considers the characteristics of AI software, the applicability and potential utility of measures and techniques identified in the first part, and reviews those few methods developed specifically for AI software. Part 3 presents an assessment and recommendations for the further exploration of this important area.

    Hospital performance measures based on patient mortality and readmission have indicated modest rates of agreement. We examined if combining clinical data on laboratory tests and vital signs with administrative data leads to improved agreement with each other, and with other measures of hospital performance in the nation's largest integrated health care system. We used patient-level administrative and clinical data, and hospital-level data on quality indicators, for 2007-2010 from the Veterans Health Administration (VA). For patients admitted for acute myocardial infarction (AMI), heart failure (HF) and pneumonia we examined changes in hospital performance on 30-d mortality and 30-d readmission rates as a result of adding clinical data to administrative data. We evaluated whether this enhancement yielded improved measures of hospital quality, based on concordance with other hospital quality indicators. For 30-d mortality, data enhancement improved model performance, and significantly changed hospital performance profiles; for 30-d readmission, the impact was modest. Concordance between enhanced measures of both outcomes, and with other hospital quality measures - including Joint Commission process measures, VA Surgical Quality Improvement Program (VASQIP) mortality and morbidity, and case volume - remained poor. Adding laboratory tests and vital signs to measure hospital performance on mortality and readmission did not improve the poor rates of agreement across hospital quality indicators in the VA. Efforts to improve risk adjustment models should continue; however, evidence of validation should precede their use as reliable measures of quality. Published by Elsevier Inc.

    Pai, Yogesh P; Chary, Satyanarayana T

    2016-04-18

    Purpose - Although measuring healthcare service quality is not a new phenomenon, the instruments used to measure are timeworn. With the shift in focus to patient centric processes in hospitals and recognizing healthcare to be different compared to other services, service quality measurement needs to be tuned specifically to healthcare. The purpose of this paper is to design a conceptual framework for measuring patient perceived hospital service quality (HSQ), based on existing service quality literature. Design/methodology/approach - Using HSQ theories, expanding existing healthcare service models and literature, a conceptual framework is proposed to measure HSQ. The paper outlines patient perceived service quality dimensions. Findings - An instrument for measuring HSQ dimensions is developed and compared with other service quality measuring instruments. The latest dimensions are in line with previous studies, but a relationship dimension is added. Practical implications - The framework empowers managers to assess healthcare quality in corporate, public and teaching hospitals. Originality/value - The paper helps academics and practitioners to assess HSQ from a patient perspective.

    Runoff properties and their changes during runoff of a 14 year old zinc roof were investigated. Zinc, lead, cadmium, pH value, rain intensity and electric conductivity have been measured for a period of one year. A runoff rate of 3.73 g/m 2 a and a volume weighted mean zinc concentration of 4.9 mg/L were determined. First flush behaviour was observed in 93% of runoff events. Low rain intensities are correlating with higher zinc concentrations in runoff, whereas the duration of antecedent dry periods could not directly be linked with initial zinc concentrations

    2003-01-01

    Nahanni National Park Reserve is located at southwestern NWT-Yukon border. One of the first UNESCO World Heritage sites, Nahanni lies within Taiga Cordillera and Taiga Shield Ecozones. Base and precious metal mining occurred upstream of Nahanni prior to park establishment. Nahanni waters, sediments, fish, and caribou have naturally elevated metals levels. Baseline water, sediment and fish tissue quality data were collected and analyzed throughout Nahanni during 1988-91 and 1992-97. These two programs characterized how aquatic quality variables are naturally varying in space and time, affected by geology, stream flow, seasonality, and extreme meteorological and geological events. Possible anthropogenic causes of aquatic quality change were examined. Measured values were compared to existing Guidelines and site-specific objectives were established.

    2006-01-01

    To evaluate the application of one particular quality measurement tool, the SERVQUAL instrument, as a potential mechanism to measure quality in services for children with disabilities Staff and family of children with an intellectual disability in two organisations providing specialist therapy and day completed an adapted SERVQUAL questionnaire. A total of 81 SERVQUAL questionnaires were distributed and 59 questionnaires were returned (response rate of 73 per cent). The SERVQUAL instrument can be considered as a useful diagnostic tool to identify particular strengths and areas for improvement in services for people with disabilities as the instrument lends itself for the monitoring of the effectiveness of quality improvement initiatives over time. The findings also showed relatively high customer expectations and the organisations involved in this research are currently not meeting all of these high expectations as significant quality gaps were found in the areas of reliability and responsiveness. The sample size was relatively small and the measurement of quality using the SERVQUAL instrument remains a challenge, due to the conceptual and empirical difficulties. The SERVQUAL instrument is probably most be attractive to service managers and funding organisations because of its ability to identify gaps in the quality of the service. The tool had been used to measure quality in services for people with disabilities and the research has shown that this tool might be an important additional quality measurement tool for services.

    External groups requiring measures now include public and private payers, regulators, accreditors and others that certify performance levels for consumers, patients and payers. Although benefits have accrued from the growth in quality measurement, the recent explosion in the number of measures threatens to shift resources from improving quality to cover a plethora of quality-performance metrics that may have a limited impact on the things that patients and payers want and need (ie, better outcomes, better care, and lower per capita costs). Here we propose a policy that quality measurement should be: balanced to meet the need of end users to judge quality and cost performance and the need of providers to continuously improve the quality, outcomes and costs of their services; and parsimonious to measure quality, outcomes and costs with appropriate metrics that are selected based on end-user needs.

Two sets of up/down symmetric poloidal views are used to measure both active emission in the plane of the neutral heating beams and background emission in a radial plane away from the neutral beams. Differential velocity measurements isolate the line-integrated poloidal velocity from apparent flows due to the energy-dependent chargeexchange cross section. Six f/1.8 spectrometers measure 276 spectra to obtain 75 active and 63 background channels every 10 ms. Local measurements from a similar midplane toroidal viewing system are mapped into two dimensions to allow the inversion of poloidal line-integrated measurements to obtain local poloidal velocity profiles. Radial resolution after inversion is 0.6-1.8 cm from the plasma edge to the center.

    National comparisons of radioactivity measurements of 131 I and 60 Co (in 2010) and of 133 Ba (in 2011) were carried out within the framework of the National Radiation Metrology Laboratory Program of Indonesia, coordinated by PTKMR-BATAN. Eleven laboratories took part in the comparison, and all measurements were made using gamma spectrometry, on point sources with an activity between 2000 Bq and 6000 Bq. Several laboratories reported values which were more than 10% different from the reference value for 131 I and 133 Ba. Possible reasons for these differences are discussed. This program will be continued with other radionuclides to maintain and control quality assurance for the local laboratories. - Highlights: • PTKMR-BATAN coordinated national comparison of 131 I, 60 Co and 133 Ba. • Eleven laboratories took part in the comparison. • All measurements were done using gamma spectrometry methods. • For 131 I and 133 Ba, 3 laboratories have more than 10% difference from reference laboratory value

    The National Quality Forum has endorsed quality-improvement measures for multiple cancer types that are being developed into actionable tools to improve cancer care. No nationally endorsed quality metrics currently exist for head and neck cancer. The authors identified patients with surgically treated, invasive, head and neck squamous cell carcinoma in the National Cancer Data Base from 2004 to 2014 and compared the rate of adherence to 5 different quality metrics and whether compliance with these quality metrics impacted overall survival. The metrics examined included negative surgical margins, neck dissection lymph node (LN) yield ≥ 18, appropriate adjuvant radiation, appropriate adjuvant chemoradiation, adjuvant therapy within 6 weeks, as well as overall quality. In total, 76,853 eligible patients were identified. There was substantial variability in patient-level adherence, which was 80% for negative surgical margins, 73.1% for neck dissection LN yield, 69% for adjuvant radiation, 42.6% for adjuvant chemoradiation, and 44.5% for adjuvant therapy within 6 weeks. Risk-adjusted Cox proportional-hazard models indicated that all metrics were associated with a reduced risk of death: negative margins (hazard ratio [HR] 0.73; 95% confidence interval [CI], 0.71-0.76), LN yield ≥ 18 (HR, 0.93; 95% CI, 0.89-0.96), adjuvant radiation (HR, 0.67; 95% CI, 0.64-0.70), adjuvant chemoradiation (HR, 0.84; 95% CI, 0.79-0.88), and adjuvant therapy ≤6 weeks (HR, 0.92; 95% CI, 0.89-0.96). Patients who received high-quality care had a 19% reduced adjusted hazard of mortality (HR, 0.81; 95% CI, 0.79-0.83). Five head and neck cancer quality metrics were identified that have substantial variability in adherence and meaningfully impact overall survival. These metrics are appropriate candidates for national adoption. Cancer 2017;123:4372-81. © 2017 American Cancer Society. © 2017 American Cancer Society.

    1996-01-01

    As part of a continuing effort to re-engineer the wind tunnel testing process, a comprehensive data quality assurance program is being established at NASA Langley Research Center (LaRC). The ultimate goal of the program is routing provision of tunnel-to-tunnel reproducibility with total uncertainty levels acceptable for test and evaluation of civilian transports. The operational elements for reaching such levels of reproducibility are: (1) statistical control, which provides long term measurement uncertainty predictability and a base for continuous improvement, (2) measurement uncertainty prediction, which provides test designs that can meet data quality expectations with the system's predictable variation, and (3) national standards, which provide a means for resolving tunnel-to-tunnel differences. The paper presents the LaRC design for the program and discusses the process of implementation.

  11. Aquatic macroinvertebrates and water quality of Sandia Canyon, Los Alamos National Laboratory, November 1993--October 1994

    Cross, S.

    1995-08-01

    The Ecological Studies Team (EST) of ESH-20 at Los Alamos National Laboratory (LANL) has collected samples from the stream within Sandia Canyon since the summer of 1990. These field studies gather water quality measurements and collect aquatic macroinvertebrates from permanent sampling sites. Reports by Bennett (1994) and Cross (1994) discuss previous EST aquatic studies in Sandia Canyon. This report updates and expands those findings. EST collected water quality data and aquatic macroinvertebrates at five permanent stations within the canyon from November 1993 through October 1994. The two upstream stations are located below outfalls that discharge industrial and sanitary waste effluent into the stream, thereby maintaining year-round flow. Some water quality parameters are different at the first three stations from those expected of natural streams in the area, indicating degraded water quality due to effluent discharges. The aquatic habitat at the upper stations has also been degraded by sedimentation and channelization. The macroinvertebrate communities at these stations are characterized by low diversities and unstable communities. In contrast, the two downstream stations appear to be in a zone of recovery, where water quality parameters more closely resemble those found in natural streams of the area. The two lower stations have increased macroinvertebrate diversity and stable communities, further indications of downstream water quality improvement.

  5. Does litigation increase or decrease health care quality?: a national study of negligence claims against nursing homes.

    The tort system is supposed to help improve the quality and safety of health care, but whether it actually does so is controversial. Most previous studies modeling the effect of negligence litigation on quality of care are ecologic. To assess whether the experience of being sued and incurring litigation costs affects the quality of care subsequently delivered in nursing homes. We linked information on 6471 negligence claims brought against 1514 nursing homes between 1998 and 2010 to indicators of nursing home quality drawn from 2 US national datasets (Online Survey, Certification, and Reporting system; Minimum Data Set Quality Measure/Indicator Reports). At the facility level, we tested for associations between 9 quality measures and 3 variables indicating the nursing homes' litigation experience in the preceding 12-18 months (total indemnity payments; total indemnity payments plus administrative costs; ≥ 1 paid claims vs. none). The analyses adjusted for quality at baseline, case-mix, ownership, occupancy, year, and facility and state random effects. Nearly all combinations of the 3 litigation exposure measures and 9 quality measures--27 models in all--showed an inverse relationship between litigation costs and quality. However, only a few of these associations were statistically significant, and the effect sizes were very small. For example, a doubling of indemnity payments was associated with a 1.1% increase in the number of deficiencies and a 2.2% increase in pressure ulcer rates. Tort litigation does not increase the quality performance of nursing homes, and may decrease it slightly.

    2010-09-01

    Recent research in range ecology has emphasized the importance of forage quality as a key indicator of rangeland condition. However, we lack tools to evaluate forage quality at scales appropriate for management. Using canopy reflectance data to measure forage quality has been conducted at both laboratory and field levels separately, but little work has been conducted to evaluate these methods simultaneously. The objective of this study is to find a reliable way of assessing grassland quality through measuring forage chemistry with reflectance. We studied a mixed grass ecosystem in Grasslands National Park of Canada and surrounding pastures, located in southern Saskatchewan. Spectral reflectance was collected at both in-situ field level and in the laboratory. Vegetation samples were collected at each site, sorted into the green grass portion, and then sent to a chemical company for measuring forage quality variables, including protein, lignin, ash, moisture at 135 °C, Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Total Digestible, Digestible Energy, Net Energy for Lactation, Net Energy for Maintenance, and Net Energy for Gain. Reflectance data were processed with the first derivative transformation and continuum removal method. Correlation analysis was conducted on spectral and forage quality variables. A regression model was further built to investigate the possibility of using canopy spectral measurements to predict the grassland quality. Results indicated that field level prediction of protein of mixed grass species was possible (r² = 0.63). However, the relationship between canopy reflectance and the other forage quality variables was not strong.

    1985-01-01

    In the operation of the National Transonic Facility (NTF) higher Reynolds numbers are obtained on the basis of a utilization of low operational temperatures and high pressures. Liquid nitrogen is used as cryogenic medium, and temperatures in the range from -320 F to 160 F can be employed. A maximum pressure of 130 psi is specified, while the NTF design parameter for the Reynolds number is 120,000,000. In view of the new requirements regarding the measurement systems, major developments had to be undertaken in virtually all wind tunnel measurement areas and, in addition, some new measurement systems were needed. Attention is given to force measurement, pressure measurement, model attitude, model deformation, and the data system.

    Donaldson, M S; Nolan, K

    1997-05-01

    September 12-13, 1996, in Washington, DC, the Institute of Medicine, as part of its Special Initiative on Health Care Quality, held an invitational conference to illustrate exemplary quality measurement and to discuss the results. Patient reports, innovative uses of outcome measures for quality improvement, risk adjustment, assessment in integrated health plans and health care settings, clinical guidelines, and projects on disseminating information on quality measurement techniques and tools were among the topics represented. Brent James described studies undertaken to reduce adverse drug events (ADEs). When implementing any measurement system where error is a possible factor, it is important to emphasize identifying problems for the purpose of learning, not judgment. Lucian Leape agreed that staff involved must feel that the purpose of the study is to examine system problems, not individuals' mistakes. David Classen described a nonproprietary computerized disease-management program designed to reduce ADEs in infectious diseases. "A QUALITY VISION": Robert Brook said that the relationship between cost or resources devoted to care and quality is not well understood and is certainly not simple. He also said that although investments in measurement strategies are needed to make them better, that doesn't mean we shouldn't attempt to use the measurements we have now. Mark Chassin said that the presentations at the conference provided evidence that should allow us to conclude beyond a reasonable doubt that quality can be measured-with a degree of scientific precision equal to that of most of the measures used to take care of patients every day.

  13. The national stream quality accounting network: A flux-basedapproach to monitoring the water quality of large rivers

    Science.gov (United States)

    Hooper, R.P.; Aulenbach, Brent T.; Kelly, V.J.

    2001-01-01

    Estimating the annual mass flux at a network of fixed stations is one approach to characterizing water quality of large rivers. The interpretive context provided by annual flux includes identifying source and sink areas for constituents and estimating the loadings to receiving waters, such as reservoirs or the ocean. Since 1995, the US Geological Survey's National Stream Quality Accounting Network (NASQAN) has employed this approach at a network of 39 stations in four of the largest river basins of the USA: The Mississippi, the Columbia, the Colorado and the Rio Grande. In this paper, the design of NASQAN is described and its effectiveness at characterizing the water quality of these rivers is evaluated using data from the first 3 years of operation. A broad range of constituents was measured by NASQAN, including trace organic and inorganic chemicals, major ions, sediment and nutrients. Where possible, a regression model relating concentration to discharge and season was used to interpolate between chemical observations for flux estimation. For water-quality network design, the most important finding from NASQAN was the importance of having a specific objective (that is, estimating annual mass flux) and, from that, an explicitly stated data analysis strategy, namely the use of regression models to interpolate between observations. The use of such models aided in the design of sampling strategy and provided a context for data review. The regression models essentially form null hypotheses for concentration variation that can be evaluated by the observed data. The feedback between network operation and data collection established by the hypothesis tests places the water-quality network on a firm scientific footing.

    In a quality inspection of a set of items where the measurements of values of a quality characteristic of the item are contaminated by random errors, one can take wrong decisions which are damageable to the quality. So of is important to control the risks in such a way that a final quality level is insured. We consider that an item is defective or not if the value G of its quality characteristic is larger or smaller than a given level g. We assume that, due to the lack of precision of the measurement instrument, the measurement M of this characteristic is expressed by ∫ (G) + ξ where f is an increasing function such that the value ∫ (g 0 ) is known and ξ is a random error with mean zero and given variance. First we study the problem of the determination of a critical measure m such that a specified quality target is reached after the classification of a lot of items where each item is accepted or rejected depending on whether its measurement is smaller or greater than m. Then we analyse the problem of testing the global quality of a lot from the measurements for a example of items taken from the lot. For these two kinds of problems and for different quality targets, we propose solutions emphasizing on the case where the function ∫ is linear and the error ξ and the variable G are Gaussian. Simulation results allow to appreciate the efficiency of the different considered control procedures and their robustness with respect to deviations from the assumptions used in the theoretical derivations.

    To describe the calculation and psychometric properties of the discharge self-care functional status quality measure implemented in the Centers for Medicare & Medicaid Services' (CMS) Inpatient Rehabilitation Facility (IRF) Quality Reporting Program on October 1, 2016. Medicare fee-for-service (FFS) patients from 38 IRFs that participated in the CMS Post-Acute Care Payment Reform Demonstration were included in this cohort study. Data came from the Continuity Assessment Record and Evaluation Item Set, IRF-Patient Assessment Instrument, and Medicare claims. For each patient, we calculated an expected discharge self-care score, risk-adjusted for demographic and baseline clinical characteristics. The performance score of each IRF equaled the percentage of patient stays where the observed discharge self-care score met or exceeded the expected score. We assessed the measure's discriminatory ability across IRFs and reliability. IRFs. Medicare FFS patients aged ≥21 years (N=4769). Not applicable. Facility-level discharge self-care quality measure performance score. A total of 4769 patient stays were included; 57% of stays were in women, and 12.1% were in patients aged quality measure showed strong reliability, with intraclass correlation coefficients of .91. The discharge self-care quality measure showed strong discriminatory ability and reliability, representing an important initial step in evaluation of IRF self-care outcomes. A wide range in performance scores suggested a gap in quality of care across IRFs. Future work should include testing the measure with nationwide data from all IRFs. Published by Elsevier Inc.

    The renal transplantation is nowadays the reference treatment of ESRD. Living donor kidney transplantation is less often performed in France than in other countries. Nevertheless, numerous French and international surveys have evidenced that it provides the recipients a longer life expectancy and a better quality of life. Donors themselves, what do they become? How are they? For the first time in France, a survey has been implemented to investigate the quality of life of living kidney donor to one of their close relations. This study has been undertaken by the Agency of the biomedecine and the service Clinical Epidemiology and Evaluation (EEC), of the University teaching hospital of Nancy. The main objective was to describe the quality of life of the living donors having given a kidney for more than a year and less than 5 years. The secondary objective was to contribute to the knowledge of the main factors associated to the living kidney donor quality of life, one year after the donation. Participants had to be living in France at the time of the donation which had taken place between June 30(th), 2005 and March 1(st), 2009. A folder gathering various self-administrated questionnaires was sent to the place of residence of the donor between March and April, 2010. These data were completed by medical data collected near the transplantation centres by the Agency of biomedecine within the framework of the register CRISTAL. They included the characteristics of the donation and of the donor at the very time of the donation, 3 months after the donation and at the last annual assessment. Three living donors in four, that is 501 persons, agreed to fully participate. They constituted a representative national sample of all the living donors of this period. The non participants were younger (4.5 years on average) and had a less adequate annual follow-up. The women were more represented (61 %) than men. The median age was 53 years. More of 2/3 were employed at the time of the

    Despite dramatic air quality improvement in the United States over the past decades, recent years have brought renewed scrutiny and uncertainty surrounding the effectiveness of specific regulatory programs for continuing to improve air quality and public health outcomes. We employ causal inference methods and a spatial hierarchical regression model to characterize the extent to which a designation of "nonattainment" with the 1997 National Ambient Air Quality Standard for ambient fine particulate matter (PM2.5) in 2005 causally affected ambient PM2.5 and health outcomes among over 10 million Medicare beneficiaries in the Eastern United States in 2009-2012. We found that, on average across all retained study locations, reductions in ambient PM2.5 and Medicare health outcomes could not be conclusively attributed to the nonattainment designations against the backdrop of other regional strategies that impacted the entire Eastern United States. A more targeted principal stratification analysis indicates substantial health impacts of the nonattainment designations among the subset of areas where the designations are estimated to have actually reduced ambient PM2.5 beyond levels achieved by regional measures, with noteworthy reductions in all-cause mortality, chronic obstructive pulmonary disorder, heart failure, ischemic heart disease, and respiratory tract infections. These findings provide targeted evidence of the effectiveness of local control measures after nonattainment designations for the 1997 PM2.5 air quality standard.

    The assessment of integral quality management (QM) in a hospital requires measurement and monitoring from different perspectives and at various levels of care delivery. Within the DUQuE project (Deepening our Understanding of Quality improvement in Europe), seven measures for QM were developed. This study investigates the relationships between the various quality measures. It is a multi-level, cross-sectional, mixed-method study. As part of the DUQuE project, we invited a random sample of 74 hospitals in 7 countries. The quality managers of these hospitals were the main respondents. Furthermore, data of site visits of external surveyors assessing the participating hospitals were used. Three measures of QM at hospitals level focusing on integral systems (QMSI), compliance with the Plan-Do-Study-Act quality improvement cycle (QMCI) and implementation of clinical quality (CQII). Four measures of QM activities at care pathway level focusing on Specialized expertise and responsibility (SER), Evidence-based organization of pathways (EBOP), Patient safety strategies (PSS) and Clinical review (CR). Positive significant associations were found between the three hospitals level QM measures. Results of the relationships between levels were mixed and showed most associations between QMCI and department-level QM measures for all four types of departments. QMSI was associated with PSS in all types of departments. By using the seven measures of QM, it is possible to get a more comprehensive picture of the maturity of QM in hospitals, with regard to the different levels and across various types of hospital departments.

    Measures of quality of life have been increasingly used in clinical trials. When designing a study, researchers must decide which quality of life measure to use. Some literature provides guidance through general recommendations, though lacks quantitative comparisons. In this report, 2 general quality of life measures, the 12-Item Short Form Health Survey (SF-12) and the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), are compared in a depressed population. STAR*D data were used to analyze the associations among the SF-12 and the Q-LES-Q. Each measure covers 6 domains, overlapping on 5 (health, self-esteem/well-being, community/productivity, social/love relationships, leisure/creativity), with the SF-12 addressing family and the Q-LES-Q addressing living situations. Strong item-by-item associations exist only between the Q-LES-Q and the SF-12 physical health items. The 2 measures overlap on the domains covered while the lack of correlation between the 2 measures may be attributed to the perspective of each question as the Q-LES-Q measures satisfaction while the SF-12 measures the patient's perception of function.

    Assessment of source and sediment quality was carried out on marine sediments collected from the Tuanku Abdul Rahman National Park. Enrichment factors (EF), pollution load index (PLI) and geo-accumulation index (Igeo) were used to identify the sources of pollution, degree of contamination and sediment quality, respectively. Elemental analyses of marine sediment samples were performed by using the Instrumental Neutron Activation Analysis (INAA). Results from the Tunku Abdul Rahman National Park of Sabah indicated that most of the elements are considered to be from lithological or natural origin with EF values of less than 2 except for As (10 stations), Cr (3 stations), Lu (5 stations), Mg (2 stations), Sb (6 stations) and U (3 stations). For the sediment quality, most of the study area can be categorised as unpolluted for most of the elements (Igeo value < 2) except for As, Cr, Lu, Mg, Sb and U. A few study areas were slightly low contaminated with As, Cr, Lu, Mg, Sb and U. The contamination of As, Cr, Lu, Mg, Sb and U in the study area can be categorised as moderate with Igeo values ranged from 1 to 2. Meanwhile, the results of PLI value for sediment were ranged from 0.93 to 1.47 (PLI < 50) indicating there are not required to perform drastic rectification measures for the screening of the elements in the Tunku Abdul Rahman Park. Overall, assessment of the sediment quality at the Tunku Abdul Rahman National Park showed a few elements such as As, Cr, Lu, Mg, Sb and U were slightly enriched while most of the elements were similar to background values.

    2012-10-01

    Full Text Available One of the main features of the human hand is its grasping ability. Robot grasping has been studied for years and different quality measures have been proposed to evaluate the stability and manipulability of grasps. Although the human hand is obviously more complex than robot hands, the methods used in robotics might be adopted to study the human grasp. The purpose of this work is to propose a set of measures that allow the evaluation of different aspects of the human grasp. The most common robotic grasp quality measures have been adapted to the evaluation of the human hand and a new quality measure – the fatigue index – is proposed in order to incorporate the biomechanical aspect into the evaluation. The minimum set of indices that allows the evaluation of the different aspects of the grasp is obtained from the analysis of a human prehension experiment.

    This study assessed the perceptions and actions of rural hospital nurse executives with regard to patient safety and quality improvement (QI). A national sample of rural hospital nurse executives (n = 300) completed a survey measuring 4 domains related to patient safety and QI: (a) patient "Safety Culture," (b) adequacy of QI "Resources," (c) "Barriers" related to QI, and (d) "Nurse Leader Engagement" in activities supporting QI. Perceptions of Safety Culture were strong but 47% of the Resources needed to carry out QI were inadequate, 29% of Barriers were moderate to major, and 25% of Nurse Leader Engagement activities were performed infrequently. Nurse Leader Engagement in quality-related activities was less frequent among nurses in isolated and small rural town hospitals compared with large rural city hospitals. To further QI, rural nurse executives may need to use their communications and actions to raise the visibility of QI.

    In order to improve the precision of radiation therapy and structure of radiation oncology, the state of quality assurance (QA) system for external radiation therapy in Japanese national hospitals and sanatoriums were investigated, by a questionnaire method. The questionnaire included the equipments, the personnel, and a frequency in quality assurance check of each radiation therapy facilities. The results clarified that real photon energy of megavoltage equipment was measured in only 57% of 58% institutions; frequency of the dose monitor calibration was suboptimal; personnel scale was markedly insufficient; some treatment-related apparatus was inappropriately arranged between institutions. Based on these results, it was considered that the precision of radiation therapy and its QA state could not be improved without personnel sufficiency. In the present situation, we should consider the arrangement of treatment facilities in each area and specialization of radiation therapy between institutions. (author)

    The National Social Life, Health, and Aging Project (NSHAP) measures seven indicators of quality of life (QoL) and psychological health. The measures used for happiness, self-esteem, depression, and loneliness are well established in the literature. Conversely, measures of anxiety, stress, and self-reported emotional health were modified for their use in this unique project. The purpose of this paper is to provide (a) an overview of NSHAP's QoL assessment and (b) evidence for the adequacy of the modified measures. First, we examined the psychometric properties of the modified measures. Second, the established QoL measures were used to examine the concurrent validity of the modified measures. Finally, gender- and age-group differences were examined for each modified measure. The anxiety index exhibited good internal reliability and concurrent validity. Consistent with the literature, a single-factor structure best fit the data. Stress was satisfactory in terms of concurrent validity but with only fair internal consistency. Self-reported emotional health exhibited good concurrent validity and moderate external validity. The modified indices used in NSHAP tended to exhibit good internal reliability and concurrent validity. These measures can confidently be used in the exploration of QoL and psychological health in later life and its many correlates.

    Quality problems in the service organisation are the result of the mismatch between prior expectation and perceived quality of the service. Each organisation will attempt to determine the requirements of its customers and translate these requirements into product and delivery process specifications. This paper examines a particular electric company (SCECO-East), a typical service provider in Saudi Arabia, in which service quality is a distinguishing feature of primary importance. It describes a detailed survey and analysis in the light of the model put forward by Parasuraman et al. It utilises SERVQUAL for measuring customers' perceptions of service quality. The study revealed that SCECO-East scored high in tangibles dimension but low in features of responsiveness and reliability. In addition, while the performance of SCECO-East was acceptable to all customer categories, service quality was perceived differently by various types of customers, with reinforcement and commercial customers awarding SCECO-East even lower ratings than other customers did.

    Full Text Available 2011 was a difficult year for all the countries, developed and emerging ones. For overcoming the negative effects of the financial crisis, many economies have established as purpose to adopt new economic policies regarding the foreign direct investment flows (FDI, even to stimulate the flows or to reduce it (protectionism measures. So, there can be identified two categories of national policies: measures for the FDI flows stimulation and measures whose aim was the weighting of FDI developing, through restriction and regulation. In the first category we could include the liberalization measures and promotional and faciletation policies. In this study we evidenced that the fundament of the second category of policies is the belief that the FDI outward lead to job exports, to a raise of unemployment and a weakness of the industrial base.Many reports on FDI flows, here we talk about those made by UNCTAD, show that the regulation and restriction policies are seen as a possible protectionism, especially in the agricultural and extractive industries, where there have been required nationalization processes and divestments. Even more, the economies which adopted this kind of policies have been less interested in investing abroad, the outward of FDI being affected and globally the total outward decreased.

    Quality improvement requires using quality measures that can be implemented in a valid manner. Using guidelines set forth by the Meaningful Use portion of the Health Information Technology for Economic and Clinical Health Act, the authors assessed the feasibility and performance of an automated electronic Meaningful Use dental clinical quality measure to determine the percentage of children who received fluoride varnish. The authors defined how to implement the automated measure queries in a dental electronic health record. Within records identified through automated query, the authors manually reviewed a subsample to assess the performance of the query. The automated query results revealed that 71.0% of patients had fluoride varnish compared with the manual chart review results that indicated 77.6% of patients had fluoride varnish. The automated quality measure performance results indicated 90.5% sensitivity, 90.8% specificity, 96.9% positive predictive value, and 75.2% negative predictive value. The authors' findings support the feasibility of using automated dental quality measure queries in the context of sufficient structured data. Information noted only in free text rather than in structured data would require using natural language processing approaches to effectively query electronic health records. To participate in self-directed quality improvement, dental clinicians must embrace the accountability era. Commitment to quality will require enhanced documentation to support near-term automated calculation of quality measures. Copyright © 2016 American Dental Association. Published by Elsevier Inc.

    A method for measuring the relative surface resistivity and quality of conductive coatings on ceramic vacuum chambers was developed. This method is unique in that it allows one to test the coating even after the ceramic chamber is installed in the accelerator and under vacuum; furthermore, the measurement provides a localized surface reading of the coating conductance. The method uses a magnetic probe is calibrated using the measured DC end-to-end resistance of the tube under test and by comparison to a high quality test surface. The measurement method has also been verified by comparison to high frequency impedance measurements. A detailed description, results, and sensitivity of the technique are given here

    Full Text Available The objective of this research is to propose procedures for measuring service life and evaluating the quality of locallymade and used solid tires in Thailand. The solid tires were stressed and rotated until blowout on a drum-like test apparatuswhich is designed, constructed by the authors and equipped with laboratory instrumentation. Solid tires from five differentmanufacturers were selected for testing. We measured service life, length of time to tire failure, at three different loadingamplitudes and three different speeds on the testing drum. The service life of all specimens was studied and compared todetermine the possibility of using service life to evaluate the quality of a solid tire.

  7. Developing a national programme of flood risk management measures: Moldova

    Full Text Available A Technical Assistance project funded by the European Investment Bank has been undertaken to develop a programme of flood risk management measures for Moldova that will address the main shortcomings in the present flood management system, and provide the basis for long-term improvement. Areas of significant flood risk were identified using national hydraulic and flood risk modelling, and flood hazard and flood risk maps were then prepared for these high risk areas. The flood risk was calculated using 12 indicators representing social, economic and environmental impacts of flooding. Indicator values were combined to provide overall estimates of flood risk. Strategic approaches to flood risk management were identified for each river basin using a multi-criteria analysis. Measures were then identified to achieve the strategic approaches. A programme of measures covering a 20-year period was developed together with a more detailed Short-Term Investment Plan covering the first seven years of the programme. Arrangements are now being made to implement the programme. The technical achievements of the project included national hydrological and hydraulic modelling covering 12,000 km of river, the development of 2-dimensional channel and floodplain hydraulic models from a range of topographic and bathymetric data, and an integrated flood risk assessment that takes account of both economic and non-monetary impacts.

    The importance of measuring the quality of end-of-life care provision is undisputed, but determining how best to achieve this is yet to be confirmed. This study sought to identify and describe national end-of-life care quality indicators and supporting policies used by countries leading in their end-of-life care provision. A systematic environmental scan that included a web search to identify relevant national policies and indicators; hand searching for additional materials; information from experts listed for the top 10 (n=15) countries ranked in the 'quality of care' category of the 2015 Quality of Death Index study; and snowballing from Index experts. Ten countries (66%) have national policy support for end-of-life care measurement, five have national indicator sets, with two indicator sets suitable for all service providers. No countries mandate indicator use, and there is limited evidence of consumer engagement in development of indicators. Two thirds of the 128 identified indicators are outcomes measures (62%), and 38% are process measures. Most indicators pertain to symptom management (38%), social care (32%) or care delivery (27%). Measurement of end-of-life care quality varies globally and rarely covers all care domains or service providers. There is a need to reduce duplication of indicator development, involve consumers, consider all care providers and ensure measurable and relevant indicators to improve end-of-life care experiences for patients and families. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Routine activity measurements of radiopharmaceutical solutions in Nuclear Medicine Centres (NMC) are carried out with the help of radionuclide calibrators (RC). These solutions are either ingested or injected to the patient for diagnosis or therapy. However, for the realization of an optimized examination, the activity of these radiopharmaceuticals must be determined accurately before administering it to patients. The primary standards are maintained by Radiation Standards Section, Radiological Physics and Advisory Division. National audit programmes of Iodine -131 activity measurements with RCs are conducted biannually to establish traceability to national standards and to check the status of nuclear medicine practice followed at the NMC. The results of fifteenth audit of 131 I activity measurements with RC are presented in this paper. Questionnaires were sent to two hundred and thirty three NMCs in-the country. One hundred and nine NMC's agreed for participation and accordingly, glass vials containing radioactive 131 I solution of nominal activity of 100 MBq were procured from Board of Radiation and Isotope Technology, Mumbai. The radioactivity in each vial was determined with high pressure re-entrant gamma ionisation chamber (GIC), a secondary standard maintained by this laboratory. The sensitivity coefficient of GIC is traceable to the primary standard. The standardized radioactive solution of 131 I in glass vial was sent to each participant. Measurements results were reported in the reporting form sent. This audit was conducted in four schedules in Jan 2013. One hundred and sixty six results were received from one hundred and nine participants as many participants took measurements on more than one isotope calibrator

    Estonia, Latvia, and Lithuania (the Baltic countries) and the Republic State of Carelia, Russia belong to the so-called nearby areas of Finland. All being part of the former Soviet Union, they are now undergoing the establishment of their own environment- managing systems. Finland has shown a great amount of interest in supporting the efforts of these areas to solve their environmental problems. In 1993 VTT started, at the request of the East European Project of the Finnish Ministry of the Environment, a four year project aiming at the establishment of national atmospheric emission measurement systems in the Baltic countries and the Republic state of Carelia (later: the counterpart countries). Proper national emission measurement systems were regarded important in order to provide reliable data on the emission situation for national and international use. The main target of the work is to raise the level of the emission measurements in the counterpart countries to the international level. Two aspects were considered to be required to achieve this goal; (1) delivery of proper emission measurement equipment, (2) training of the emission measurement personnel. It was estimated that within three to four years these counterpart countries could join the Finnish quality assurance system in emission measurements if desired. (author)

    2018-01-01

    We conducted a systematic review of clinical guidelines (CGs) to examine the methodological approaches of quality indicator derivation in CGs, the frequency of quality indicators to check CG recommendations in routine care, and clinimetric properties of quality indicators. We analyzed the publicly available CG databases of the Association of the Scientific Medical Societies in Germany (AWMF) and National Institute for Health and Care Excellence (NICE). Data on the methodology of subsequent quality indicator derivation, the content and definition of recommended quality indicators, and clinimetric properties of measurement instruments were extracted. In Germany, no explicit methodological guidance exists, but 3 different approaches are used. For NICE, a general approach is used for the derivation of quality indicators out of quality standards. Quality indicators were defined in 34 out of 87 CGs (39%) in Germany and for 58 out of 133 (43%) NICE CGs. Statements regarding measurement properties of instruments for quality indicator assessment were missing in German and NICE documents. Thirteen pairs of CGs (32%) have associated quality indicators. Thirty-four quality indicators refer to the same aspect of the quality of care, which corresponds to 27% of the German and 7% of NICE quality indicators. The development of a standardized and internationally accepted methodology for the derivation of quality indicators relevant to CGs is needed to measure and compare quality of care in health care systems.

    Fixed air quality stations have limitations when used to assess people's real life exposure to air pollutants. Their spatial coverage is too limited to capture the spatial variability in, e.g., an urban or industrial environment. Complementary mobile air quality measurements can be used as an additional tool to fill this void. In this publication we present the Aeroflex, a bicycle for mobile air quality monitoring. The Aeroflex is equipped with compact air quality measurement devices to monitor ultrafine particle number counts, particulate mass and black carbon concentrations at a high resolution (up to 1 second). Each measurement is automatically linked to its geographical location and time of acquisition using GPS and Internet time. Furthermore, the Aeroflex is equipped with automated data transmission, data pre-processing and data visualization. The Aeroflex is designed with adaptability, reliability and user friendliness in mind. Over the past years, the Aeroflex has been successfully used for high resolution air quality mapping, exposure assessment and hot spot identification. PMID:23262484

    Full Text Available By the end of the 1980s, the central issue of development was focused on the growth of income and not on the growth of quality of life. Therefore, the development strategies were oriented towards production and left no significant space for improving the welfare of individuals.In the beginning of the 1990s, the human development concept emerged, stressing that economic development ultimately should result in growth of quality of life of individuals, while the goal of the development process was to expand the capabilities of individuals by placing them in the focus of the efforts for development.This paper if focused on the quality of life of the individuals. Moreover, in addition to the previous practice in Macedonia of calculating the human development index (HDI - as a measure of quality of life, an attempt will be made to calculate the humanpoverty index (HPI-2 - as a measure of non-income poverty, gender development index (GDI - as a measure of inequality between men and women, as well as the human development index at the level of aggregated urban and rural municipalities.We hope that it will contribute to the improvement of the quality of decisions made by the state and local authorities in Macedonia when it comes to issues concerning the human development.

    Full Text Available For some companies, visual inspection has become an essential step when seeking to improve the quality of their products. The aim of this control is to be sure of the perceived quality of the product, which often goes well beyond the quality expected by the customer. For this type of control, the controller should be able to detect any anomaly on a product, characterize this anomaly, and then evaluate it in order to decide if the product should be accepted or rejected. This paper describes how this characterization can be carried out and, more specifically, how to measure the impact of the local environment of an anomaly on the perceived quality of the product.

  18. Quality and noise measurements in mobile phone video capture

    Petrescu, Doina; Pincenti, John

    2011-02-01

    The quality of videos captured with mobile phones has become increasingly important particularly since resolutions and formats have reached a level that rivals the capabilities available in the digital camcorder market, and since many mobile phones now allow direct playback on large HDTVs. The video quality is determined by the combined quality of the individual parts of the imaging system including the image sensor, the digital color processing, and the video compression, each of which has been studied independently. In this work, we study the combined effect of these elements on the overall video quality. We do this by evaluating the capture under various lighting, color processing, and video compression conditions. First, we measure full reference quality metrics between encoder input and the reconstructed sequence, where the encoder input changes with light and color processing modifications. Second, we introduce a system model which includes all elements that affect video quality, including a low light additive noise model, ISP color processing, as well as the video encoder. Our experiments show that in low light conditions and for certain choices of color processing the system level visual quality may not improve when the encoder becomes more capable or the compression ratio is reduced.

  19. Resolving the double tension: Toward a new approach to measurement modeling in cross-national research

    Science.gov (United States)

    Medina, Tait Runnfeldt

    The increasing global reach of survey research provides sociologists with new opportunities to pursue theory building and refinement through comparative analysis. However, comparison across a broad array of diverse contexts introduces methodological complexities related to the development of constructs (i.e., measurement modeling) that if not adequately recognized and properly addressed undermine the quality of research findings and cast doubt on the validity of substantive conclusions. The motivation for this dissertation arises from a concern that the availability of cross-national survey data has outpaced sociologists' ability to appropriately analyze and draw meaningful conclusions from such data. I examine the implicit assumptions and detail the limitations of three commonly used measurement models in cross-national analysis---summative scale, pooled factor model, and multiple-group factor model with measurement invariance. Using the orienting lens of the double tension I argue that a new approach to measurement modeling that incorporates important cross-national differences into the measurement process is needed. Two such measurement models---multiple-group factor model with partial measurement invariance (Byrne, Shavelson and Muthen 1989) and the alignment method (Asparouhov and Muthen 2014; Muthen and Asparouhov 2014)---are discussed in detail and illustrated using a sociologically relevant substantive example. I demonstrate that the former approach is vulnerable to an identification problem that arbitrarily impacts substantive conclusions. I conclude that the alignment method is built on model assumptions that are consistent with theoretical understandings of cross-national comparability and provides an approach to measurement modeling and construct development that is uniquely suited for cross-national research. The dissertation makes three major contributions: First, it provides theoretical justification for a new cross-national measurement model and

    Asthma is a frequent chronic inflammatory disease of the airways, and the assessment of health-related quality of life (HrQoL) is important in both research and routine care. Various asthma-specific measures of HrQoL exist but there is uncertainty which measures are best suited for use in research and routine care. Therefore, the aim of the proposed research is a comprehensive systematic assessment of the measurement properties of the existing measures that were developed to measure asthma-specific quality of life. This study is a systematic review of the measurement properties of asthma-specific measures of health-related quality of life. PubMed and Embase will be searched using a selection of relevant search terms. Eligible studies will be primary empirical studies evaluating, describing or comparing measurement properties of asthma-specific HRQL tools. Eligibility assessment and data abstraction will be performed independently by two reviewers. Evidence tables will be generated for study characteristics, instrument characteristics, measurement properties and interpretability. The quality of the measurement properties will be assessed using predefined criteria. Methodological quality of studies will be assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. A best evidence synthesis will be undertaken if more than one study have investigated a particular measurement property. The proposed systematic review will produce a comprehensive assessment of measurement properties of existing measures of asthma-specific health-related quality of life. We also aim to derive recommendations in order to help researchers and practitioners alike in the choice of instrument. PROSPERO registration number: CRD42014010491.

    The purpose of this study was to ensure accuracy in radiation dose delivery, external dosimetry quality audit has an equal importance with routine dosimetry performed at clinics. To do so, dosimetry quality audit was organized by the Secondary Standard Dosimetry Laboratory (SSDL) of Pakistan Institute of Nuclear Science and Technology (PINSTECH) at the national level to investigate and minimize uncertainties involved in the measurement of absorbed dose, and to improve the accuracy of dose measurement at different radiotherapy hospitals. A total of 181 dosimetry quality audits (i.e., 102 of Co-60 and 79 of linear accelerators) for teletherapy units installed at 22 different sites were performed from 1989 to 2015. The percent deviation between users’ calculated/stated dose and evaluated dose (in the result of on-site dosimetry visits) were calculated and the results were analyzed with respect to the limits of ± 2.5% (ICRU "optimal model") ± 3.0% (IAEA on-site dosimetry visits limit) and ± 5.0% (ICRU minimal or "lowest acceptable" model). The results showed that out of 181 total on-site dosimetry visits, 20.44%, 16.02%, and 4.42% were out of acceptable limits of ± 2.5% ± 3.0%, and ± 5.0%, respectively. The importance of a proper ongoing quality assurance program, recommendations of the followed protocols, and properly calibrated thermometers, pressure gauges, and humidity meters at radiotherapy hospitals are essential in maintaining consistency and uniformity of absorbed dose measurements for precision in dose delivery.

    The objective was to examine the relationship between health care costs and quality in rheumatoid arthritis (RA). Administrative claims were used to calculate 8 process measures for the treatment of RA. Associated health care costs were calculated for members who achieved or did not achieve each of the measures. Medical, pharmacy, and laboratory claims for RA patients (International Classification of Diseases, Ninth Revision, Clinical Modification 714.x) were extracted from the Optum Clinformatics Datamart database for 2011. Individuals were predominately female and in their mid-fifties. Measure achievement ranged from 55.9% to 80.8%. The mean cost of care for members meeting the measure was $18,644; members who did not meet the measures had a mean cost of $14,973. Primary cost drivers were pharmacy and office expenses, accounting for 42.4% and 26.3% of total costs, respectively. Regression analyses revealed statistically significant associations between biologic usage, which was more prevalent in groups attaining measures, and total expenditure across all measures (Ps < 0.001). Pharmacy costs were similar between both groups. Individuals meeting the measures had a higher proportion of costs accounted for by office visits; those not meeting the measures had a higher proportion of costs from inpatient and outpatient visits. These findings suggest that increased quality may lead to lower inpatient and outpatient hospital costs. Yet, the overall cost of RA care is likely to remain high because of intensive pharmacotherapy regimens.

    1997-01-01

    In Finland, the general principles and objectives of the QA are being more and more incorporated in the basic curricula of radiotherapy professionals: radiotherapists, radiation technologists (nurses), and the physicists, in particular. The medical physicists are identified as an independent specialty which, after the general studies in physics requires a special examination and five years practicing in various aspects of radiotherapy clinical work. Specific meetings organized both occasionally and regularly by national societies, hospitals and the authorities collect together different specialists in the field, thus providing opportunities for continuous up-keeping of knowledge and the exchange of experiences in QA. The Finnish Centre for Radiation and nuclear Safety (STUK), operating under the Ministry of Social Affairs and Health, is the national authority for radiation protection covering all fields of the application of radiation. Besides its supervisory role, i.e. to control that the safety of various applications meets the requirements et by legislation, considerable amount of the resources are devoted to research in support of the supervisory activities. For radiotherapy, the leading principle is to ensure the safety of patients, personnel and the public, the good accuracy of the dose to the patient being one of the main objectives. In essence, this leading principle manifests itself through the maintenance of standards, measurement techniques and calibration services traceable to the international measurement system, and through the legal inspections as well as independent reviews and measurements to assess the QA systems of hospitals (i.e. through Dosimetry Audits or Quality Audits)

    Objectives Publicly available hospital quality reports seek to inform consumers of important healthcare quality and affordability attributes, and may inform consumer decision-making. To understand how much consumers search for such information online on one Internet search engine, whether they mention such information in social media and how positively they view this information. Setting and design A leading Internet search engine (Google) was the main focus of the study. Google Trends and Google Adwords keyword analyses were performed for national and Californian searches between 1 August 2012 and 31 July 2013 for keywords related to ‘top hospital’, best hospital’, and ‘hospital quality’, as well as for six specific hospital quality reports. Separately, a proprietary social media monitoring tool was used to investigate blog, forum, social media and traditional media mentions of, and sentiment towards, major public reports of hospital quality in California in 2012. Primary outcome measures (1) Counts of searches for keywords performed on Google; (2) counts of and (3) sentiment of mentions of public reports on social media. Results National Google search volume for 75 hospital quality-related terms averaged 610 700 searches per month with strong variation by keyword and by state. A commercial report (Healthgrades) was more commonly searched for nationally on Google than the federal government's Hospital Compare, which otherwise dominated quality-related search terms. Social media references in California to quality reports were generally few, and commercially produced hospital quality reports were more widely mentioned than state (Office of Statewide Healthcare Planning and Development (OSHPD)), or non-profit (CalHospitalCompare) reports. Conclusions Consumers are somewhat aware of hospital quality based on Internet search activity and social media disclosures. Public stakeholders may be able to broaden their quality dissemination initiatives by

    Proximity to public open space, such as parks and other green spaces, has considerable health benefits, and people have been shown to be more likely to use such space for physical activity if it is of high quality. This paper describes a new remote-assessment approach that makes use of Google Earth Pro (the free version of this program is Google Earth) to provide rapid and inexpensive measurement of the quality of public open space. The aim of the study was to assess the correlation between assessments of the quality of public open space using (1) the remote method (making use of Google Earth Pro) and (2) direct observation with a well-established measure of quality, the Public Open Space Tool (POST). Fifty parks selected from the southwest part of Sydney, Australia, were assessed in 2009 with the remote method (using Google Earth Pro), and scores were compared with those obtained from direct observation of the same parks using POST. The time taken to conduct the assessments using each method was also recorded. Raters for each method were blind to scores obtained from using the other method. Analyses were conducted in 2009. The Spearman correlation coefficient between the quality scores obtained for the 50 parks using the remote method and direct observation was 0.9 (pspaces without the need for in-person visits, dramatically reducing the time required for environmental audits of public open space.

    Full Text Available Modern methods aimed to ensure the quality of foods require to implement and certify quality management systems in processing plants. In this case, to measure the effectiveness of existing QMS is often a very difficult task for the leadership due to the fragmentation of the measured metrics, or even lack thereof. This points to the relevance of the conducted research.The criteria for effectiveness assessment of the production process of meat processing plants with the use of scaling methods and Shewhart control charts are presented in the article. The authors developed and presented the formulae for the calculation of single indicators used for the further comprehensive assessment. The algorithm of statistical evaluation of the process controllability, which allows in an accessible form to estimate the statistical control of production processes and to organize statistical quality control in the development of quality management systems, is presented The proposed procedure is based on a process approach, the essence of which is the application of the Deming cycle: “Plan — Do — Check — Act”, which makes it easy to integrate it into any existing quality management system.

    The issues surrounding the measurement and provision of service quality in a health care setting are becoming increasingly important to nursing. This research study aims to apply the SERVQUAL measurement instrument in a Scottish colposcopy clinic. The study involved adapting the SERVQUAL instrument to the colposcopy setting and asking a sample of patients to complete the questionnaire. Patient expectations of service were obtained on first attendance at the clinic. Patient perceptions of service received were obtained on completion of treatment. Perceptions and expectations are then compared to identify where the largest service gaps exist. Although patient satisfaction with the overall service provided was generally high, the instrument provided evidence of where specific service improvements were needed. The largest service quality gap was for the reliability of service. The research also revealed the need for improved premises. Although the study has a limited sample size, it does appear that the SERVQUAL instrument has a useful diagnostic role to play in assessing and monitoring service quality in nursing, enabling nursing staff to identify where improvements are needed from the patients' perspective. The study has raised a number of issues which would form the basis for useful further research. Service quality from the patients' perspective should be routinely monitored and assessed. The findings should be useful to nursing staff seeking to assess, and improve, service quality.

    The National Park Service (NPS) organized more than 270 parks with important natural resources into 32 ecoregional networks to conduct Inventory and Monitoring (I&M) activities for assessment of natural resources within park units. The Missouri National Recreational River (NRR) is among the 13 parks in the NPS Northern Great Plain Network (NGPN). Park managers and NGPN staff identified surface water resources as a high priority vital sign to monitor in park units. The objectives for the Missouri NRR water quality sampling design are to (1) assess the current status and long-term trends of select water quality parameters; and (2) document trends in streamflow at high-priority stream systems. Due to the large size of the Missouri River main stem, the NGPN water quality design for the Missouri NRR focuses on wadeable tributaries within the park unit. To correlate with the NGPN water quality protocols, monitoring of the Missouri NRR consists of measurement of field core parameters including dissolved oxygen, pH, specific conductance, and temperature; and streamflow. The purpose of this document is to discuss factors examined for selection of water quality monitoring on segments of the Missouri River tributaries within the Missouri NRR.Awareness of the complex history of the Missouri NRR aids in the current understanding and direction for designing a monitoring plan. Historical and current monitoring data from agencies and entities were examined to assess potential NGPN monitoring sites. In addition, the U.S. Environmental Protection Agency 303(d) list was examined for the impaired segments on tributaries to the Missouri River main stem. Because major tributaries integrate water quality effects from complex combinations of land use and environmental settings within contributing areas, a 20-mile buffer of the Missouri NRR was used to establish environmental settings that may impact the water quality of tributaries that feed the Missouri River main stem. For selection of

    The U.S. Geological Survey publishes information on concentrations and loads of water-quality constituents at 111 sites across the United States as part of the U.S. Geological Survey National Water Quality Network (NWQN). This report details historical and updated methods for computing water-quality loads at NWQN sites. The primary updates to historical load estimation methods include (1) an adaptation to methods for computing loads to the Gulf of Mexico; (2) the inclusion of loads computed using the Weighted Regressions on Time, Discharge, and Season (WRTDS) method; and (3) the inclusion of loads computed using continuous water-quality data. Loads computed using WRTDS and continuous water-quality data are provided along with those computed using historical methods. Various aspects of method updates are evaluated in this report to help users of water-quality loading data determine which estimation methods best suit their particular application.

    Not all software used in the nuclear industry needs the rigorous formal verification, reliability testing and quality assessment that are being applied to safety critical software. Recently, however, there is increasing recognition that systematic and objective quality assessment of the scientific software used in design and safety analyses of nuclear facilities is necessary to support safety and licensing decisions. Because of the complexity and large size of these programs and the resource constraints faced by the AECB reviewer, it is desirable that appropriate automated tools are used wherever practical. To objectively assess the quality of software, a set of attributes of a software product by which its quality is described and evaluated must be established. These attributes must be relevant to the application domain of software under evaluation. To effectively assess the quality of software, metrics defining quantitative scale and method appropriate to determine the value of attributes need to be applied. To cost-effectively perform the evaluation, use of suitable automated tools is desirable. In this project, criteria for evaluating the quality of scientific software are presented; metrics for which those criteria can be evaluated are identified; a survey of automated tools to measure those metrics was conducted and the most appropriate tool (QA Fortran) was acquired; and the tool usage was demonstrated on three sample programs.

    With the number of tourists coming to Taiwan growing by 10-20 % since 2010, the number has increased due to an increasing number of foreign tourists, particularly after deregulation allowed admitting tourist groups, followed later on by foreign individual tourists, from mainland China. The purpose of this study is to propose a revised gap model to evaluate and improve service quality in Taiwanese hotel industry. Thus, service quality could be clearly measured through gap analysis, which was more effective for offering direction in developing and improving service quality. The HOLSERV instrument was used to identify and analyze service gaps from the perceptions of internal and external customers. The sample for this study included three main categories of respondents: tourists, employees, and managers. The results show that five gaps influenced tourists' evaluations of service quality. In particular, the study revealed that Gap 1 (management perceptions vs. customer expectations) and Gap 9 (service provider perceptions of management perceptions vs. service delivery) were more critical than the others in affecting perceived service quality, making service delivery the main area of improvement. This study contributes toward an evaluation of the service quality of the Taiwanese hotel industry from the perspectives of customers, service providers, and managers, which is considerably valuable for hotel managers. It was the aim of this study to explore all of these together in order to better understand the possible gaps in the hotel industry in Taiwan.

    Presently, most of the laser beam quality measurement system collimates the optical path manually with low efficiency and low repeatability. To solve these problems, this paper proposed a new collimated method to improve the reliability and accuracy of the measurement results. The system accuracy controlled the position of the mirror to change laser beam propagation direction, which can realize the beam perpendicularly incident to the photosurface of camera. The experiment results show that the proposed system has good repeatability and the measuring deviation of M2 factor is less than 0.6%.

    Full Text Available The quality assurance of the two Brewer spectrophotometers of the Finnish Meteorological Institute is discussed in this paper. The complete data processing chain from raw signal to high quality spectra is presented. The quality assurance includes daily maintenance, laboratory characterizations, calculation of long-term spectral responsivity, data processing and quality assessment. The cosine correction of the measurements is based on a new method, and is included in the data processing software. The results showed that the actual cosine correction factor of the two Finnish Brewers can vary between 1.08–1.13 and 1.08–1.12, respectively, depending on the sky radiance distribution and wavelength. The temperature characterization showed a linear temperature dependence between the instruments' internal temperature and the photon counts per cycle, and a temperature correction was used for correcting the measurements. The long-term spectral responsivity was calculated using the time series of several lamps using two slightly different methods. The long-term spectral responsivity was scaled to the irradiance scale of the Helsinki University of Technology (HUT for the whole of the measurement time-periods 1990–2006 and 1995–2006 for Sodankylä and Jokioinen, respectively. Both Brewers have participated in many international spectroradiometer comparisons, and have shown good stability. The differences between the Brewers and the portable reference spectroradiometer QASUME have been within 5% during 2002–2007.

    Testing laboratory accredited according to ISO/IEC 17025:2005 has to ensure the quality of their results. Important aspect of correct evaluation of the result is the accuracy and uncertainty. Requirement of ISO/IEC 17025:2005 is the accredited laboratories to express their results with the corresponding uncertainty. Participation of laboratories in interlaboratory comparisons provides objective evidence of the level of reliability and quality of their results. Thereby the competency of accredited laboratories verified, including the verification of the declared measurement uncertainty. Some interlaboratory comparisons in which took participation the Testing Laboratory of Radiochemical Analysis (LARCHA) are presented.

  9. Measurement of Quality of Life I. A Methodological Framework

    2003-01-01

    Full Text Available Despite the widespread acceptance of quality of life (QOL as the ideal guideline in healthcare and clinical research, serious conceptual and methodological problems continue to plague this area. In an attempt to remedy this situation, we propose seven criteria that a quality-of-life concept must meet to provide a sound basis for investigation by questionnaire. The seven criteria or desiderata are: (1 an explicit definition of quality of life; (2 a coherent philosophy of human life from which the definition is derived; (3 a theory that operationalizes the philosophy by specifying unambiguous, nonoverlapping, and jointly exhaustive questionnaire items; (4 response alternatives that permit a fraction-scale interpretation; (5 technical checks of reproducibility; (6 meaningfulness to investigators, respondents, and users; and (7 an overall aesthetic appeal of the questionnaire. These criteria have guided the design of a validated 5-item generic, global quality-of-life questionnaire (QOL5, and a validated 317-item generic, global quality-of-life questionnaire (SEQOL, administered to a well-documented birth cohort of 7,400 Danes born in 1959�1961, as well as to a reference sample of 2,500 Danes. Presented in outline, the underlying integrative quality-of-life (IQOL theory is a meta-theory. To illustrate the seven criteria at work, we show the extent to which they are satisfied by one of the eight component theories. Next, two sample results of our investigation are presented: satisfaction with one's sex life has the expected covariation with one's quality of life, and so does mother's smoking during pregnancy, albeit to a much smaller extent. It is concluded that the methodological framework presented has proved helpful in designing a questionnaire that is capable of yielding acceptably valid and reliable measurements of global and generic quality of life.

    Improved diagnosis of coeliac disease has increased incidence and therefore burden on the health care system. There are no quality outcome measures (QOM) in use nationally to assess hospital management of this condition. This study applied QOM devised by the East of England paediatric gastroenterology network to 99 patients reviewed at two tertiary hospitals in the Network, to assess the quality of care provided by nurse led and doctor led care models. The average performance across all QOM was 96.2% at Addenbrooke’s Hospital (AH), and 98.7% at Norfolk and Norwich Hospital (NNUH), whilst 95% (n = 18) of QOM were met. Patient satisfaction was high at both sites (uptake of questionnaire 53 of 99 patients in the study). The study showed a comparably high level of care delivered by both a nurse and doctor led service. Our quality assessment tools could be applied in the future by other centres to measure standards of care. PMID:24284612

    The U.S. Geological Survey (USGS) and the National Park Service (NPS) work together through the USGS–NPS Water-Quality Partnership to support a broad range of policy and management needs related to high-priority water-quality issues in national parks. The program was initiated in 1998 as part of the Clean Water Action Plan, a Presidential initiative to commemorate the 25th anniversary of the Clean Water Act. Partnership projects are developed jointly by the USGS and the NPS. Studies are conducted by the USGS and findings are used by the NPS to guide policy and management actions aimed at protecting and improving water quality.The National Park Service manages many of our Nation’s most highly valued aquatic systems across the country, including portions of the Great Lakes, ocean and coastal zones, historic canals, reservoirs, large rivers, high-elevation lakes and streams, geysers, springs, and wetlands. So far, the Water-Quality Partnership has undertaken 217 projects in 119 national parks. In each project, USGS studies and assessments (http://water.usgs.gov/nps_partnership/pubs.php) have supported science-based management by the NPS to protect and improve water quality in parks. Some of the current projects are highlighted in the NPS Call to Action Centennial initiative, Crystal Clear, which celebrates national park water-resource efforts to ensure clean water for the next century of park management (http://www.nature.nps.gov/water/crystalclear/).New projects are proposed each year by USGS scientists working in collaboration with NPS staff in specific parks. Project selection is highly competitive, with an average of only eight new projects funded each year out of approximately 75 proposals that are submitted. Since the beginning of the Partnership in 1998, 189 publications detailing project findings have been completed. The 217 studies have been conducted in 119 NPS-administered lands, extending from Denali National Park and Preserve in Alaska to Everglades

    The U.S. Geological Survey, in cooperation with the National Park Service conducted an intensive assessment of selected springs along the Colorado River Corridor in Arches National Park, Canyonlands National Park, Glen Canyon National Recreation Area, and Grand Canyon National Park in 1997 and 1998, for the purpose of measuring and evaluating the water quality and quantity of the resource. This study was conducted to establish baseline data for the future evaluation of possible effects from recreational use and climate change. Selected springs and seeps were visited over a study period from 1997 to 1998, during which, discharge and on-site chemical measurements were made at selected springs and seeps, and samples were collected for subsequent chemical laboratory analysis. This interdisciplinary study also includes simultaneous studies of flora and fauna, measured and sampled coincidently at the same sites. Samples collected during this study were transported to U.S. Geological Survey laboratories in Boulder, Colorado, where analyses were performed using state-of-the-art laboratory technology. The location of the selected springs and seeps, elevation, geology, aspect, and onsite measurements including temperature, discharge, dissolved oxygen, pH, and specific conductance, were recorded. Laboratory analyses include determinations for alkalinity, aluminum, ammonium (nitrogen), antimony, arsenic, barium, beryllium, bismuth, boron, bromide, cadmium, calcium, cerium, cesium, chloride, chromium, cobalt, copper, dissolved inorganic carbon, dissolved organic carbon, dysprosium, erbium, europium, fluoride, gadolinium, holmium, iodine, iron, lanthanum, lead, lithium, lutetium, magnesium, manganese, mercury, molybdenum, neodymium, nickel, nitrate (nitrogen), nitrite (nitrogen), phosphate, phosphorus, potassium, praseodymium, rhenium, rubidium, samarium, selenium, silica, silver, sodium, strontium, sulfate, tellurium, terbium, thallium, thorium, thulium, tin, titanium, tungsten

    1977-12-01

    Instrumentation and techniques were developed at Argonne National Laboratory for measuring the three-dimensional temperature structure of thermal plumes from power plants, along with the limnological, meteorological, and plant operating conditions affecting their behavior. The equipment and procedures were designed to provide field data for use in evaluating predictive models that describe thermal plume behavior, and over 100 sets of these data have been collected. The instrument systems and techniques employed in a typical thermal discharge survey are highly integrated. Continuous monitoring of ambient and plant conditions is coupled with plume mapping from a moving survey boat. The instantaneous location of the boat together with subsurface temperature measurements from a towed thermistor chain provide a quasisynoptic view of the plume structure. Real-time, onboard display of the boat path and vertical temperatures supply feedback to investigators for determining the extent and spatial resolution of measurements required. The unique design, reliability, accuracy, calibration, and historical development of the components of these integrated systems are described. Survey system interfaces with data handling and processing techniques are also explained. Special supportive studies to investigate plume dynamics, values of eddy diffusivities, time-temperature histories of water parcels in thermal plumes, and rapid changes in plume shape are also described along with instrumentation used

    This study was created by the Accreditation Association for Ambulatory Health Care Institute for Quality Improvement to measure clinical performance and improvement opportunities for physicians and ambulatory health-care organizations. Data were collected prospectively between February 2001 and August 2002. Thirty-nine study centers participated, and 688 patients who had tumescent liposuction were surveyed and followed for 6 months. The objective was to determine patient satisfaction with tumescent liposuction and examine current liposuction practice and the safety of tumescent liposuction in a representative cohort of patients. The Accreditation Association for Ambulatory Health Care Institute for Quality Improvement collected prospective data from February 2001 to August 2002 from 68 organizations registered for this study. Ultimately 39 organizations submitted 688 useable cases performed totally with local anesthesia, "tumescent technique." The overall clinical complication rate found in the Accreditation Association for Ambulatory Health Care Institute for Quality Improvement study was 0.7% (5 of 702). There was a minor complication rate of 0.57%. The major complication rate was 0.14% with one patient requiring hospitalization. Seventy-five percent of the patients reported no discomfort during their procedures. Of the 59% of patients who responded to a 6-month postoperative survey, 91% were positive about their decision to have liposuction (rating of 4 or 5 on a scale of 1-5) and 84% had high levels (4 or 5 on a scale of 1-5) of overall satisfaction with the procedure. Our findings are consistent with others in that tumescent liposuction is a safe procedure with a low complication rate and high patient satisfaction.

    The US National Park Service (NPS) characterizes night sky conditions over Chaco Culture National Historical Park using measurements in the park and satellite data. The park is located near the geographic center of the San Juan Basin of northwestern New Mexico and the adjacent Four Corners state. In the park, we capture a series of night sky images in V-band using our mobile camera system on nine nights from 2001 to 2016 at four sites. We perform absolute photometric calibration and determine the image placement to obtain multiple 45-million-pixel mosaic images of the entire night sky. We also model the regional night sky conditions in and around the park based on 2016 VIIRS satellite data. The average zenith brightness is 21.5 mag/arcsec2, and the whole sky is only ~16% brighter than the natural conditions. The faintest stars visible to naked eyes have magnitude of approximately 7.0, reaching the sensitivity limit of human eyes. The main impacts to Chaco’s night sky quality are the light domes from Albuquerque, Rio Rancho, Farmington, Bloomfield, Gallup, Santa Fe, Grants, and Crown Point. A few of these light domes exceed the natural brightness of the Milky Way. Additionally, glare sources from oil and gas development sites are visible along the north and east horizons. Overall, the night sky quality at Chaco Culture National Historical Park is very good. The park preserves to a large extent the natural illumination cycles, providing a refuge for crepuscular and nocturnal species. During clear and dark nights, visitors have an opportunity to see the Milky Way from nearly horizon to horizon, complete constellations, and faint astronomical objects and natural sources of light such as the Andromeda Galaxy, zodiacal light, and airglow.

    Background The tort system is supposed to help improve the quality and safety of health care, but whether it actually does so is controversial. Most previous studies modeling the effect of negligence litigation on quality of care are ecologic. Objective To assess whether the experience of being sued and incurring litigation costs affects the quality of care subsequently delivered in nursing homes. Research Design, Subjects, Measures We linked information on 6,471 negligence claims brought against 1,514 nursing homes between 1998 and 2010 to indicators of nursing home quality drawn from two U.S. national datasets (Online Survey, Certification, and Reporting system; Minimum Data Set Quality Measure/Indicator Reports). At the facility level, we tested for associations between 9 quality measures and 3 variables indicating the nursing homes’ litigation experience in the preceding 12–18 months (total indemnity payments; total indemnity payments plus administrative costs; ≥1 paid claims vs. none). The analyses adjusted for quality at baseline, case-mix, ownership, occupancy, year, and facility and state random effects. Results Nearly all combinations of the 3 litigation exposure measures and 9 quality measures—27 models in all—showed an inverse relationship between litigation costs and quality. However only a few of these associations were statistically significant, and the effect sizes were very small. For example, a doubling of indemnity payments was associated with a 1.1% increase in the number of deficiencies and a 2.2% increase in pressure ulcer rates. Conclusions Tort litigation does not increase the quality performance of nursing homes, and may decrease it slightly. PMID:23552438

    The U.S. Geological Survey, in cooperation with the U.S. Fish and Wildlife Service collected data on water and bottom-sediment chemistry to be used to evaluate a new water rights acquisition program designed to enhance wetland habitat in Stillwater National Wildlife Refuge and in Lahontan Valley, Churchill County, Nevada. The area supports habitat critical to the feeding and resting of migratory birds travelling the Pacific Flyway. Information about how water rights acquisitions may affect the quality of water delivered to the wetlands is needed by stakeholders and Stillwater National Wildlife Refuge managers in order to evaluate the effectiveness of this approach to wetlands management. A network of six sites on waterways that deliver the majority of water to Refuge wetlands was established to monitor the quality of streamflow and bottom sediment. Each site was visited every 4 to 6 weeks and selected water-quality field parameters were measured when flowing water was present. Water samples were collected at varying frequencies and analyzed for major ions, silica, and organic carbon, and for selected species of nitrogen and phosphorus, trace elements, pharmaceuticals, and other trace organic compounds. Bottom-sediment samples were collected for analysis of selected trace elements.Dissolved-solids concentrations exceeded the recommended criterion for protection of aquatic life (500 milligrams per liter) in 33 of 62 filtered water samples. The maximum arsenic criterion (340 micrograms per liter) was exceeded twice and the continuous criterion was exceeded seven times. Criteria protecting aquatic life from continuous exposure to aluminum, cadmium, lead, and mercury (87, 0.72, 2.5, and 0.77 micrograms per liter, respectively) were exceeded only once in filtered samples (27, 40, 32, and 36 samples, respectively). Mercury was the only trace element analyzed in bottom-sediment samples to exceed the published probable effect concentration (1,060 micrograms per kilogram).

    National Wildlife Refuges may have impaired water quality resulting from historic and current land uses, upstream sources, and aerial pollutant deposition. National Wildlife Refuge staff have limited time available to identify and evaluate potential water quality issues. As a result, water quality–related issues may not be resolved until a problem has already arisen. The National Wildlife Refuge System Water Quality Information System (WQIS) is a relational database developed for use by U.S. Fish and Wildlife Service staff to identify existing water quality issues on refuges in the United States. The WQIS database relies on a geospatial overlay analysis of data layers for ownership, streams and water quality. The WQIS provides summary statistics of 303(d) impaired waters and total maximum daily loads for the National Wildlife Refuge System at the national, regional, and refuge level. The WQIS allows U.S. Fish and Wildlife Service staff to be proactive in addressing water quality issues by identifying and understanding the current extent and nature of 303(d) impaired waters and subsequent total maximum daily loads. Water quality data are updated bi-annually, making it necessary to refresh the WQIS to maintain up-to-date information. This manual outlines the steps necessary to update the data and reports in the WQIS.

    Low rates of compliance with quality measures for inflammatory bowel disease (IBD) have been reported for US gastroenterologists. We assessed the influence of quality improvement (QI) education on compliance with physician quality reporting system (PQRS) measures for IBD and measures related to National Quality Strategy (NQS) priorities. Forty community-based gastroenterologists participated in the QI study; 20 were assigned to educational intervention and control groups, respectively. At baseline, randomly selected charts of patients with moderate-to-severe ulcerative colitis were retrospectively reviewed for the gastroenterologists' performance of 8 PQRS IBD measures and 4 NQS-related measures. The intervention group participated in a series of accredited continuing medical education (CME) activities focusing on QI. Follow-up chart reviews were conducted 6 months after the CME activities. Independent t tests were conducted to compare between-group differences in baseline-to-follow-up rates of documented compliance with each measure. The analysis included 299 baseline charts and 300 follow-up charts. The intervention group had significantly greater magnitudes of improvement than the control group for the following measures: assessment of IBD type, location, and activity (+14 %, p = 0.009); influenza vaccination (+13 %, p = 0.025); pneumococcal vaccination (+20 %, p = 0.003); testing for latent tuberculosis before anti-TNF-α therapy (+10 %, p = 0.028); assessment of hepatitis B virus status before anti-TNF-α therapy (+9 %, p = 0.010); assessment of side effects (+17 %, p = 0.048), and counseling patients about cancer risks (+13 %, p = 0.013). QI-focused CME improves community-based gastroenterologists' compliance with IBD quality measures and measures aligned with NQS priorities.

    Full Text Available RESEARCH OBJECTIVE: This study examines the perspectives of a range of key hospital staff on the use, importance, scientific background, availability of data, feasibility of data collection, cost benefit aspects and availability of professional personnel for measurement of quality indicators among Iranian hospitals. The study aims to facilitate the use of quality indicators to improve quality of care in hospitals. STUDY DESIGN: A cross-sectional study was conducted over the period 2009 to 2010. Staff at Iranian hospitals completed a self-administered questionnaire eliciting their views on organizational, clinical process, and outcome (clinical effectiveness, patient safety and patient centeredness indicators. POPULATION STUDIED: 93 hospital frontline staff including hospital/nursing managers, medical doctors, nurses, and quality improvement/medical records officers in 48 general and specialized hospitals in Iran. PRINCIPAL FINDINGS: On average, only 69% of respondents reported using quality indicators in practice at their affiliated hospitals. Respondents varied significantly in their reported use of organizational, clinical process and outcome quality indicators. Overall, clinical process and effectiveness indicators were reported to be least used. The reported use of indicators corresponded with their perceived level of importance. Quality indicators were reported to be used among clinical staff significantly more than among managerial staff. In total, 74% of the respondents reported to use obligatory indicators, while this was 68% for voluntary indicators (p<0.05. CONCLUSIONS: There is a general awareness of the importance and usability of quality indicators among hospital staff in Iran, but their use is currently mostly directed towards external accountability purposes. To increase the formative use of quality indicators, creation of a common culture and feeling of shared ownership, alongside an increased uptake of clinical process and

    This article will demonstrate how to conduct a quality improvement project using the change idea generated in "How To Use Quality Improvement Tools in Clinical Practice: How To Diagnose Solutions to a Quality of Care Problem" by Dr. Ziv Harel and colleagues in this Moving Points feature. This change idea involves the introduction of a nurse educator into a CKD clinic with a goal of increasing rates of patients performing dialysis independently at home (home hemodialysis or peritoneal dialysis). Using this example, we will illustrate a Plan-Do-Study-Act (PDSA) cycle in action and highlight the principles of rapid cycle change methodology. We will then discuss the selection of outcome, process, and balancing measures, and the practicalities of collecting these data in the clinic environment. We will also introduce the PDSA worksheet as a practical way to oversee the progress of a quality improvement project. Finally, we will demonstrate how run charts are used to visually illustrate improvement in real time, and how this information can be used to validate achievement, respond appropriately to challenges the project may encounter, and prove the significance of results. This article aims to provide readers with a clear and practical framework upon which to trial their own ideas for quality improvement in the clinical setting.

    Full Text Available The implementation of Internet technology in business has enabled the development of e-business supply chains with large-scale information integration among all partners.The development of information systems (IS is based on the established business objectives whose achievement, among other things, directly depends on the quality of development and design of IS. In the process of analysis of the key elements of company operations in the supply chain, process model and corresponding data model are designed which should enable selection of appropriate information system architecture. The quality of the implemented information system, which supports e-supply chain, directly depends on the level of data model quality. One of the serious limitations of the data model is its complexity. With a large number of entities, data model is difficult to analyse, monitor and maintain. The problem gets bigger when looking at an integrated data model at the level of participating partners in the supply chain, where the data model usually consists of hundreds or even thousands of entities.The paper will analyse the key elements affecting the quality of data models and show their interactions and factors of significance. In addition, the paper presents various measures for assessing the quality of the data model on which it is possible to easily locate the problems and focus efforts in specific parts of a complex data model where it is not economically feasible to review every detail of the model.

    1979-01-01

    In the autumn of 1975 the Supraregional Assay Service established a Quality Control Sub-Committee and the intra-laboratory QC Scheme for Growth Hormone (HGH) assays which is described here has served, in many respects, as a pilot scheme for protein RIA. Major improvements in accuracy, precision and between-laboratory agreement can be brought about by intensively interactive quality control schemes. A common standard is essential and should consist of ampoules used for one or only a small number of assays. Accuracy and agreement were not good enough to allow the overall means to serve as target values but a group of 11 laboratories were sufficiently accurate to provide a 'reference group mean' to so serve. Gross non-specificity was related to poor assay design and was quickly eliminated. Within-laboratory between-batch variability was much worse than that normally claimed for simple protein hormone RIA. A full report on this Scheme will appear shortly in Annals of Clinical Biochemistry. (Auth.)

  4. Quality Measures for Dialysis: Time for a Balanced Scorecard.

    2016-02-05

    Recent federal legislation establishes a merit-based incentive payment system for physicians, with a scorecard for each professional. The Centers for Medicare and Medicaid Services evaluate quality of care with clinical performance measures and have used these metrics for public reporting and payment to dialysis facilities. Similar metrics may be used for the future merit-based incentive payment system. In nephrology, most clinical performance measures measure processes and intermediate outcomes of care. These metrics were developed from population studies of best practice and do not identify opportunities for individualizing care on the basis of patient characteristics and individual goals of treatment. The In-Center Hemodialysis (ICH) Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey examines patients' perception of care and has entered the arena to evaluate quality of care. A balanced scorecard of quality performance should include three elements: population-based best clinical practice, patient perceptions, and individually crafted patient goals of care.

    One explanation for productivity dispersion is that the quality of inputs differs across firms. We add labor market history variables such as experience and firm and industry tenure, as well as general human capital measures such as schooling and sex. Adding these variables decreases the ratio...... of the 90th to 10th productivity quantiles from 3.27 to 2.68 across eight Danish manufacturing and service industries. We also use the wage bill and worker fixed effects. We find that the wage bill explains as much dispersion as human capital measures....

    water quality. The significant time lag between a waterquality change in one part of an aquifer system and the effects of that change at a downgradient site, such as a well, results from the generally slow movement of ground water. This lag between cause and observed effect needs to be considered in evaluating the effectiveness of current and future ground-water policies and remedial measures.Conclusive answers to questions about the location, extent, and severity of ground-water contamination, and about trends in ground-water quality, must await further collection and analysis of data from the Nation's aquifers. Generalizations, however, can be made, and the 1986 National Water Summary, which describes the natural quality of ground-water resources in each State and the major contamination problems that have been identified as of 1986, provides a national perspective of the ground-water-quality situation.The 1986 National Water Summary follows the format of previous volumes. It contains three parts, and the contents of each of these parts are highlighted below.

    Groundwater-quality data were collected from 559 wells as part of the National Water-Quality Assessment Project of the U.S. Geological Survey National Water-Quality Program from January through December 2014. The data were collected from four types of well networks: principal aquifer study networks, which are used to assess the quality of groundwater used for public water supply; land-use study networks, which are used to assess land-use effects on shallow groundwater quality; major aquifer study networks, which are used to assess the quality of groundwater used for domestic supply; and enhanced trends networks, which are used to evaluate the time scales during which groundwater quality changes. Groundwater samples were analyzed for a large number of water-quality indicators and constituents, including major ions, nutrients, trace elements, volatile organic compounds, pesticides, radionuclides, and some constituents of special interest (arsenic speciation, chromium [VI] and perchlorate). These groundwater-quality data, along with data from quality-control samples, are tabulated in this report and in an associated data release.

    2017-02-01

    We outline the development of a Mental Health Domain to track accessibility and quality of mental health care in the United States Veterans Health Administration (VHA) as part of a broad-based performance measurement system. This domain adds an important element to national performance improvement efforts by targeting regional and facility leadership and providing them a concise yet comprehensive measure to identify facilities facing challenges in their mental health programs. We present the conceptual framework and rationale behind measure selection and development. The Mental Health Domain covers three important aspects of mental health treatment: Population Coverage, Continuity of Care, and Experience of Care. Each component is a composite of existing and newly adapted measures with moderate to high internal consistency; components are statistically independent or moderately related. Development and dissemination of the Mental Health Domain involved a variety of approaches and benefited from close collaboration between local, regional, and national leadership and from coordination with existing quality-improvement initiatives. During the first year of use, facilities varied in the direction and extent of change. These patterns of change were generally consistent with qualitative information, providing support for the validity of the domain and its component measures. Measure maintenance remains an iterative process as the VHA mental health system and potential data resources continue to evolve. Lessons learned may be helpful to the broader mental health-provider community as mental health care consolidates and becomes increasingly integrated within healthcare systems.

A quality assurance program is vital to the project because Nuclear Regulatory Commission (NRC), Environmental Protection Agency (EPA) and state environmental regulations must be demonstrably met (the work must be defensible in a court of law). The end result of quality assurance (QA) is, by definition, a product of demonstrable quality. In the laboratory, this entails traceability, repeatability, and credibility. This paper describes the application of QA in grout technology development at Oak Ridge National Laboratory

  10. Response Burden in Official Business Surveys: Measurement and Reduction Practices of National Statistical Institutes

    2015-12-01

    Full Text Available Response burden in business surveys has long been a concern for National Statistical Institutes (NSIs for three types of reasons: political reasons, because response burden is part of the total administrative burden governments impose on businesses; methodological reasons, because an excessive response burden may reduce data quality and increase data-collection costs; and strategic reasons, because it affects relations between the NSIs and the business community. This article investigates NSI practices concerning business response burden measurement and reduction actions based on a survey of 41 NSIs from 39 countries. Most NSIs monitor at least some burden aspects and have implemented some actions to reduce burden, but large differences exist between NSIs’ methodologies for burden measurement and actions taken to reduce burden. Future research should find ways to deal with methodological differences in burden conceptualization, operationalization, and measurement, and provide insights into the effectiveness and efficiency of burden-reduction actions.

  11. Power quality measurement service in the support of large customers

    Power quality and how it is measured among Hydro Quebec's major customers were the focus of this conference presentation. Background information on Hydro Quebec and its customers was provided with reference to information on clients, employees and how the organization is organized. The presentation also included a discussion of power quality and how it is delivered at Hydro Quebec. For example, characteristics and target values of the voltage supplied by Hydro Quebec for high, medium and low voltages were examined. Personnel responsible for the grid have created a system to document each event submitted by customers. Documenting the actual power quality at the point of common coupling allows benchmarking of real data against announced characteristics and target values. This approach quantifies disturbances and helps to find and focus on disturbances that really influence large customers, mainly industrials. Portable and permanent installations issues were discussed followed by a discussion of a new service offering power quality metering on a regular basis. This metering service includes a complete analysis and technical support with dedicated expertise since customers are rarely fully experienced in power quality. The metering service is presented from the perspective of preventive maintenance with continuous quantification of a large number of indicators to assess the quality of the delivered power. Essential tools that customers can benefit from with this new service include real time electronic mail notification, weekly reporting and ad hoc technical support. This combination of various levels of services allows Hydro-Quebec to address the needs of these large customers in a flexible way. figs.

  12. Assuring measurement quality in person-centred healthcare

    Is it realistic to aspire to the same kind of quality-assurance of measurement in person-centred care, currently being implemented in healthcare globally, as is established in the physical sciences and engineering? Ensuring metrological comparability (‘traceability’) and reliably declaring measurement uncertainty when assessing patient ability or increased social capital are however challenging for subjective measurements often characterised by large dispersion. Drawing simple analogies between ‘instruments’ in the social sciences—questionnaires, ability tests, etc—and engineering instruments such as thermometers does not go far enough. A possible way forward, apparently equally applicable to both physical and social measurement, seems to be to model inferences in terms of performance metrics of a measurement system. Person-centred care needs person-centred measurement and a full picture of the measurement process when man acts as a measurement instrument is given in the present paper. This complements previous work by presenting the process, step by step, from the observed indication (e.g. probability of success, P success, of achieving a task), through restitution with Rasch measurement theory, to the measurand (e.g. task difficulty). Rasch invariant measure theory can yield quantities—‘latent’ (or ‘explanatory’) variables such as task challenge or person ability—with characteristics akin to those of physical quantities. Metrological references for comparability via traceability and reliable estimates of uncertainty and decision risks are then in reach even for perceptive measurements (and other qualitative properties). As a case study, the person-centred measurement of cognitive ability is examined, as part of the EU project EMPIR 15HLT04 NeuroMet, for Alzheimer’s, where better analysis of correlations with brain atrophy is enabled thanks to the Rasch metrological approach.

    The U.S. Geological Survey began its National Water-Quality Assessment (NAWQA) Program in 1991, systematically collecting chemical, biological, and physical water-quality data from study units (basins) across the Nation. In 1999, the NAWQA Program developed a data warehouse to better facilitate national and regional analysis of data from 36 study units started in 1991 and 1994. Data from 15 study units started in 1997 were added to the warehouse in 2001. The warehouse currently contains and links the following data: -- Chemical concentrations in water, sediment, and aquatic-organism tissues and related quality-control data from the USGS National Water Information System (NWIS), -- Biological data for stream-habitat and ecological-community data on fish, algae, and benthic invertebrates, -- Site, well, and basin information associated with thousands of descriptive variables derived from spatial analysis, like land use, soil, and population density, and -- Daily streamflow and temperature information from NWIS for selected sampling sites.

    Field blanks are quality-control samples used to assess contamination in environmental water samples. Contamination is the unintentional introduction of a chemical (pesticides in this instance) into an environmental water sample from sources such as inadequately cleaned equipment, dirty hands, dust, rain, or fumes. Contamination causes a positive bias in analytical measurements that may need to be considered in the analysis and interpretation of the environmental data. Estimates of pesticide contamination in environmental water samples collected for the National Water-Quality Assessment (NAWQA) Program are used to qualify, where needed, interpretations of the occurrence and distribution of pesticides in the surface and ground waters of the United States.

    The reliable quantification of ultraviolet (UV) radiation at the earth's surface requires accurate measurements of spectral global solar UV irradiance in order to determine the UV exposure to human skin and to understand long-term trends in this parameter. Array spectroradiometers (ASRMs) are small, light, robust and cost-effective instruments, and are increasingly used for spectral irradiance measurements. Within the European EMRP ENV03 project "Solar UV", new devices, guidelines and characterization methods have been developed to improve solar UV measurements with ASRMs, and support to the end user community has been provided. In order to assess the quality of 14 end user ASRMs, a solar UV intercomparison was held on the measurement platform of the World Radiation Center (PMOD/WRC) in Davos, Switzerland, from 10 to 17 July 2014. The results of the blind intercomparison revealed that ASRMs, currently used for solar UV measurements, show a large variation in the quality of their solar UV measurements. Most of the instruments overestimate the erythema-weighted UV index - in particular at large solar zenith angles - due to stray light contribution in the UV-B range. The spectral analysis of global solar UV irradiance further supported the finding that the uncertainties in the UV-B range are very large due to stray light contribution in this wavelength range. In summary, the UV index may be detected by some commercially available ASRMs within 5 % compared to the world reference spectroradiometer, if well characterized and calibrated, but only for a limited range of solar zenith angles. Generally, the tested instruments are not yet suitable for solar UV measurements for the entire range between 290 and 400 nm under all atmospheric conditions.

  16. A quantitative method for measuring the quality of history matches

    History matching can be an efficient tool for reservoir characterization. A {open_quotes}good{close_quotes} history matching job can generate reliable reservoir parameters. However, reservoir engineers are often frustrated when they try to select a {open_quotes}better{close_quotes} match from a series of history matching runs. Without a quantitative measurement, it is always difficult to tell the difference between a {open_quotes}good{close_quotes} and a {open_quotes}better{close_quotes} matches. For this reason, we need a quantitative method for testing the quality of matches. This paper presents a method for such a purpose. The method uses three statistical indices to (1) test shape conformity, (2) examine bias errors, and (3) measure magnitude of deviation. The shape conformity test insures that the shape of a simulated curve matches that of a historical curve. Examining bias errors assures that model reservoir parameters have been calibrated to that of a real reservoir. Measuring the magnitude of deviation assures that the difference between the model and the real reservoir parameters is minimized. The method was first tested on a hypothetical model and then applied to published field studies. The results showed that the method can efficiently measure the quality of matches. It also showed that the method can serve as a diagnostic tool for calibrating reservoir parameters during history matching.

    SOLVE is the Dutch abbreviation for fast solutions for air and traffic and is a website by means of which provinces and municipalities in the Netherlands can gain insight into the best measures for traffic to improve the quality of the ambient air. Since halfway June 2008, the effects on air quality of approximately 35 traffic measures were included in the SOLVE mix of measures. The effects of traffic measures on emissions of particulate matter and nitrogen dioxide have been calculated. The effects are expressed in a decrease of the contribution of traffic indicated in a scale from A (very large decrease) to E (no decrease). The outcome depends on the location where the measure is implemented. [mk] [nl

    2010-01-01

    The noise created by a supersonic aircraft is a primary concern in the design of future high-speed planes. The jet noise reduction technologies required on these aircraft will be developed using scale-models mounted to experimental jet rigs designed to simulate the exhaust gases from a full-scale jet engine. The jet noise data collected in these experiments must accurately predict the noise levels produced by the full-scale hardware in order to be a useful development tool. A methodology has been adopted at the NASA Glenn Research Center s Aero-Acoustic Propulsion Laboratory to insure the quality of the supersonic jet noise data acquired from the facility s High Flow Jet Exit Rig so that it can be used to develop future nozzle technologies that reduce supersonic jet noise. The methodology relies on mitigating extraneous noise sources, examining the impact of measurement location on the acoustic results, and investigating the facility independence of the measurements. The methodology is documented here as a basis for validating future improvements and its limitations are noted so that they do not affect the data analysis. Maintaining a high quality jet noise laboratory is an ongoing process. By carefully examining the data produced and continually following this methodology, data quality can be maintained and improved over time.

  19. Air quality measurements in urban green areas - a case study

    Science.gov (United States)

    Kuttler, W.; Strassburger, A.

    The influence of traffic-induced pollutants (e.g. CO, NO, NO 2 and O 3) on the air quality of urban areas was investigated in the city of Essen, North Rhine-Westphalia (NRW), Germany. Twelve air hygiene profile measuring trips were made to analyse the trace gas distribution in the urban area with high spatial resolution and to compare the air hygiene situation of urban green areas with the overall situation of urban pollution. Seventeen measurements were made to determine the diurnal concentration courses within urban parks (summer conditions: 13 measurements, 530 30 min mean values, winter conditions: 4 measurements, 128 30 min mean values). The measurements were carried out during mainly calm wind and cloudless conditions between February 1995 and March 1996. It was possible to establish highly differentiated spatial concentration patterns within the urban area. These patterns were correlated with five general types of land use (motorway, main road, secondary road, residential area, green area) which were influenced to varying degrees by traffic emissions. Urban parks downwind from the main emission sources show the following typical temporal concentration courses: In summer rush-hour-dependent CO, NO and NO 2 maxima only occurred in the morning. A high NO 2/NO ratio was established during weather conditions with high global radiation intensities ( K>800 W m -2), which may result in a high O 3 formation potential. Some of the values measured found in one of the parks investigated (Gruga Park, Essen, area: 0.7 km 2), which were as high as 275 μg m -3 O 3 (30-min mean value) were significantly higher than the German air quality standard of 120 μg m -3 (30-min mean value, VDI Guideline 2310, 1996) which currently applies in Germany and about 20% above the maximum values measured on the same day by the network of the North Rhine-Westphalian State Environment Agency. In winter high CO and NO concentrations occur in the morning and during the afternoon rush-hour. The

    2008-03-01

    Full Text Available Today’s businesses depend heavily on electrical services for lighting, general power, computer hardware and communications hardware. With the generalized use of sophisticated electronic devices, industries are shifting toward almost entirely electronic IT systems. PQ events are of increasing concern for the economy because today’s equipment, particularly computers and automated manufacturing devices, is highly sensitive to such imperfections. Traditionally the control and supervision of a plant distribution network has mainly been focused on the protection of the network. Relatively little attention has been focused on the quality of the electrical energy. Metering technologies and communications systems have advanced to enable the development of web-based sensors. Power Quality is one area where these smart sensors can be very valuable. This paper investigates the challenges and possibilities in the development of distributed PQ measurement systems. This paper describes the challenges and lessons learned from this work.

    1999-07-01

    The UK has implemented a system of Local Air Quality Management (LAQM) to tackle the many contemporary sources of air pollution, notably transport, industry and domestic fuel burning, in a holistic manner. The current legislation stems from the Environment Act 1995, which required a National Air Quality Strategy (NAQS) to be published outlining the Governments policies with respect to the assessment and management of air quality. The NAQS, originally published in March 1997, is on a rolling programme of reviews in order to reflect developments in European legislation, technological and scientific advances, improved air pollution modelling techniques and an increasingly better understanding of the economic and social issues involved. Following the first review (currently at consultation state), this paper will comment on how the proposed changes may affect the LAQM process. The proposed changes will also be summarised and discussed in the context of European Union air quality objectives and the economic analysis of NAQS.

    Five external quality-assurance programs were operated by the U.S. Geological Survey for the National Atmospheric Deposition Program/National Trends Network (NADP/NTN) from 2000 through 2001 (study period): the intersite-comparison program, the blind-audit program, the field-audit program, the interlaboratory-comparison program, and the collocated-sampler program. Each program is designed to measure specific components of the total error inherent in NADP/NTN wet-deposition measurements. The intersite-comparison program assesses the variability and bias of pH and specific-conductance determinations made by NADP/NTN site operators with respect to accuracy goals. The accuracy goals are statistically based using the median of all of the measurements obtained for each of four intersite-comparison studies. The percentage of site operators responding on time that met the pH accuracy goals ranged from 84.2 to 90.5 percent. In these same four intersite-comparison studies, 88.9 to 99.0 percent of the site operators met the accuracy goals for specific conductance. The blind-audit program evaluates the effects of routine sample handling, processing, and shipping on the chemistry of weekly precipitation samples. The blind-audit data for the study period indicate that sample handling introduced a small amount of sulfate contamination and slight changes to hydrogen-ion content of the precipitation samples. The magnitudes of the paired differences are not environmentally significant to NADP/NTN data users. The field-audit program (also known as the 'field-blank program') was designed to measure the effects of field exposure, handling, and processing on the chemistry of NADP/NTN precipitation samples. The results indicate potential low-level contamination of NADP/NTN samples with calcium, ammonium, chloride, and nitrate. Less sodium contamination was detected by the field-audit data than in previous years. Statistical analysis of the paired differences shows that contaminant ions

    Full Text Available The analysed theme of this article is based on the training of environmental measurements for workplaces. This is very important for sustainable quality in technical educational institutions. Applied kinds of software, which are taught at technical educational institutions, have to offer the professional and methodical knowledge concerning conditions of working ambient for students of selected technical specialisations. This skill is performed in such a way that the graduates, after entering the practical professional life, will be able to participate in solutions for actual problems that are related to environmental protection by means of software support. Nowadays, during the training processit is also obligatory to introduce technical science. Taking into consideration the above-mentioned facts it is possible to say that information technology support for environmental study subjects is a relevant aspect, which should be integrated into the university educational process. There is an effective progress that further highlights the focus on the quality of university education not only for environmental engineers. Actual trends require an increasing number of software/hardware educated engineers who can participate in qualitative university preparation, i.e.IT environmentalists. The Department of Environmental Engineering at the Faculty of Mechanical Engineering, TechnicalUniversity in Košice, Slovakia is an institution specified and intended for quality objectivisation. This institution introduced into the study programmes (“Environmental Management” and “Technology of Environmental Protection” study subjects with the software support, which are oriented towards outdoor and indoor ambient and in this way the Department of Process and Environmental Engineering is integrated effectively and intensively into the area of measurement training with regard to the requirement of quality educational processes.

  7. Air Quality Science and Regulatory Efforts Require Geostationary Satellite Measurements

    Science.gov (United States)

    2006-01-01

    Air quality scientists and regulatory agencies would benefit from the high spatial and temporal resolution trace gas and aerosol data that could be provided by instruments on a geostationary platform. More detailed time-resolved data from a geostationary platform could be used in tracking regional transport and in evaluating mesoscale air quality model performance in terms of photochemical evolution throughout the day. The diurnal cycle of photochemical pollutants is currently missing from the data provided by the current generation of atmospheric chemistry satellites which provide only one measurement per day. Often peak surface ozone mixing ratios are reached much earlier in the day during major regional pollution episodes than during local episodes due to downward mixing of ozone that had been transported above the boundary layer overnight. The regional air quality models often do not simulate this downward mixing well enough and underestimate surface ozone in regional episodes. Having high time-resolution geostationary data will make it possible to determine the magnitude of this lower-and mid-tropospheric transport that contributes to peak eight-hour average ozone and 24-hour average PM2.5 concentrations. We will show ozone and PM(sub 2.5) episodes from the CMAQ model and suggest ways in which geostationary satellite data would improve air quality forecasting. Current regulatory modeling is typically being performed at 12 km horizontal resolution. State and regional air quality regulators in regions with complex topography and/or land-sea breezes are anxious to move to 4-km or finer resolution simulations. Geostationary data at these or finer resolutions will be useful in evaluating such models.

    2011-10-01

    The articles in this supplement present recent advances in the measurement of patient-reported health-related quality-of-life (HRQOL) outcomes. Specifically, these articles highlight the combined efforts of the National Institutes of Health, National Institute for Neurological Disorders and Stroke, National Center on Medical Rehabilitation Research, National Institute on Disability and Rehabilitation Research, and Department of Veterans Affairs Rehabilitation Research and Development Service to improve HRQOL measurement. In addition, this supplement is intended to provide rehabilitation professionals with information about these efforts and the implications that these advances in outcomes measurement have for rehabilitation medicine and clinical practice. These new measurement scales use state-of-the-art method techniques, including item response theory and computerized adaptive testing. In addition, scale development involves both qualitative and quantitative methods, as well as the administration of items to hundreds or even thousands of research participants. The scales deliberately have been built with overlap of items between scales so that linkages and equivalency scores can be computed. Ultimately, these scales should facilitate direct comparison of outcomes instruments across studies and will serve as standard data elements across research trials without compromising the specificity of disease- or condition-targeted measures. This supplement includes the initial publications for many of these new measurement initiatives, each of which provides researchers and clinicians with better tools for evaluation of the efficacy of their interventions.

    2013-09-01

    Disposable absorbent products are widely used in inpatient care settings and in the community to manage adult urinary and fecal incontinence, but few product standards exist to help guide their production or optimal use. Increasing costs and reduced revenues have caused a number of states to evaluate absorbent product use among persons who receive care at home with the assistance of the Medicaid Waiver Program, further increasing concerns about the lack of product performance standards. To address these issues, the National Association For Continence (NAFC) formed a council of experts and key stakeholders with the objective of establishing national, independent quality performance standards for disposable absorbent products provided by states to Waiver Program recipients. The Council consisted of representatives from five purposefully selected states, technical directors from six nonwoven product manufacturers, an officer of the nonwoven manufactures trade association, a delegate from an academic nursing program and professional societies, a family caregiver, and a patient representative. Following a consensus method and guidelines for use, nine specific recommendations were developed, posted for public comment, and further refined. Final recommendations for product performance assessment include: rewet rate (a measure of a product's ability to withstand multiple incontinent episodes between changes), rate of acquisition (a measure of the speed at which urine is drawn away from the skin by a product, product retention capacity (a measure of a product's capacity to hold fluid without rewetting the skin), sizing options, absorbency levels, product safety, closure technology, breathable zones (a measure of the air permeability across a textile-like fabric at a controlled differential pressure), and elasticity. The Council also set values for and recommended four quantifiable parameters, and the testing methodology associated with each, to help consumers and states

  10. Autonomous Quality Control of Joint Orientation Measured with Inertial Sensors

    2016-07-01

    Full Text Available Clinical mobility assessment is traditionally performed in laboratories using complex and expensive equipment. The low accessibility to such equipment, combined with the emerging trend to assess mobility in a free-living environment, creates a need for body-worn sensors (e.g., inertial measurement units—IMUs that are capable of measuring the complexity in motor performance using meaningful measurements, such as joint orientation. However, accuracy of joint orientation estimates using IMUs may be affected by environment, the joint tracked, type of motion performed and velocity. This study investigates a quality control (QC process to assess the quality of orientation data based on features extracted from the raw inertial sensors’ signals. Joint orientation (trunk, hip, knee, ankle of twenty participants was acquired by an optical motion capture system and IMUs during a variety of tasks (sit, sit-to-stand transition, walking, turning performed under varying conditions (speed, environment. An artificial neural network was used to classify good and bad sequences of joint orientation with a sensitivity and a specificity above 83%. This study confirms the possibility to perform QC on IMU joint orientation data based on raw signal features. This innovative QC approach may be of particular interest in a big data context, such as for remote-monitoring of patients’ mobility.

    Measurements have been made of the in-flight dynamics of imploding capsules indirectly driven by laser energies of 1-1.7 MJ at the National Ignition Facility [Miller et al., Nucl. Fusion 44, 228 (2004)]. These experiments were part of the National Ignition Campaign [Landen et al., Phys. Plasmas 18, 051002 (2011)] to iteratively optimize the inputs required to achieve thermonuclear ignition in the laboratory. Using gated or streaked hard x-ray radiography, a suite of ablator performance parameters, including the time-resolved radius, velocity, mass, and thickness, have been determined throughout the acceleration history of surrogate gas-filled implosions. These measurements have been used to establish a dynamically consistent model of the ablative drive history and shell compressibility throughout the implosion trajectory. First results showed that the peak velocity of the original 1.3-MJ Ge-doped polymer (CH) point design using Au hohlraums reached only 75% of the required ignition velocity. Several capsule, hohlraum, and laser pulse changes were then implemented to improve this and other aspects of implosion performance and a dedicated effort was undertaken to test the sensitivity of the ablative drive to the rise time and length of the main laser pulse. Changing to Si rather than Ge-doped inner ablator layers and increasing the pulse length together raised peak velocity to 93% {+-} 5% of the ignition goal using a 1.5 MJ, 420 TW pulse. Further lengthening the pulse so that the laser remained on until the capsule reached 30% (rather than 60%-70%) of its initial radius, reduced the shell thickness and improved the final fuel {rho}R on companion shots with a cryogenic hydrogen fuel layer. Improved drive efficiency was observed using U rather than Au hohlraums, which was expected, and by slowing the rise time of laser pulse, which was not.

    Measurements have been made of the in-flight dynamics of imploding capsules indirectly driven by laser energies of 1–1.7 MJ at the National Ignition Facility [Miller et al., Nucl. Fusion 44, 228 (2004)]. These experiments were part of the National Ignition Campaign [Landen et al., Phys. Plasmas 18, 051002 (2011)] to iteratively optimize the inputs required to achieve thermonuclear ignition in the laboratory. Using gated or streaked hard x-ray radiography, a suite of ablator performance parameters, including the time-resolved radius, velocity, mass, and thickness, have been determined throughout the acceleration history of surrogate gas-filled implosions. These measurements have been used to establish a dynamically consistent model of the ablative drive history and shell compressibility throughout the implosion trajectory. First results showed that the peak velocity of the original 1.3-MJ Ge-doped polymer (CH) point design using Au hohlraums reached only 75% of the required ignition velocity. Several capsule, hohlraum, and laser pulse changes were then implemented to improve this and other aspects of implosion performance and a dedicated effort was undertaken to test the sensitivity of the ablative drive to the rise time and length of the main laser pulse. Changing to Si rather than Ge-doped inner ablator layers and increasing the pulse length together raised peak velocity to 93% ± 5% of the ignition goal using a 1.5 MJ, 420 TW pulse. Further lengthening the pulse so that the laser remained on until the capsule reached 30% (rather than 60%–70%) of its initial radius, reduced the shell thickness and improved the final fuel ρR on companion shots with a cryogenic hydrogen fuel layer.

  14. Accreditation of Medical Education Programs: Moving From Student Outcomes to Continuous Quality Improvement Measures.

    Accreditation of undergraduate medical education programs aims to ensure the quality of medical education and promote quality improvement, with the ultimate goal of providing optimal patient care. Direct linkages between accreditation and education quality are, however, difficult to establish. The literature examining the impact of accreditation predominantly focuses on student outcomes, such as performances on national examinations. However, student outcomes present challenges with regard to data availability, comparability, and contamination.The true impact of accreditation may well rest in its ability to promote continuous quality improvement (CQI) within medical education programs. The conceptual model grounding this paper suggests accreditation leads medical schools to commit resources to and engage in self-assessment activities that represent best practices of CQI, leading to the development within schools of a culture of CQI. In line with this model, measures of the impact of accreditation on medical schools need to include CQI-related markers. The CQI orientation of organizations can be measured using validated instruments from the business and management fields. Repeated determinations of medical schools' CQI orientation at various points throughout their accreditation cycles could provide additional evidence of the impact of accreditation on medical education. Strong CQI orientation should lead to high-quality medical education and would serve as a proxy marker for the quality of graduates and possibly for the quality of care they provide.It is time to move away from a focus on student outcomes as measures of the impact of accreditation and embrace additional markers, such as indicators of organizational CQI orientation.

    To design and deliver high quality, safe and effective products, manufacturers of in vitro diagnostic (IVD) products follow a structured, traceable process for controlling the uncertainty of results reported from their measurement systems. This process and its results however, are not often shared in detail with those outside of the manufacturing company. The objective of this paper is to facilitate discussion by describing some of the best practices used during the IVD design and development process, highlighting some design challenges manufacturers face, and to offer ideas for how IVD manufacturers and laboratories could work together to drive further improvement to public health.

    Full Text Available Quality of Life (QoL is a descriptive term that refers to people’s emotional, social and physical wellbeing, and their ability to function in the ordinary task of living. The importance of QoL makes it critical to improve and refine measure to understand patients’ experience of health, illness and treatment. However individuals change with time and the basis on which they make a QoL judgment may also change, a phenomenon increasingly referred to as response shift. The definition of response shift is recalibration of internal standards of measurement and reconceptualization of the meaning of item. The purpose of study is to discuss the effects of response shift bias. [TAF Prev Med Bull 2006; 5(5.000: 382-389

    The Harmonising Outcome Measures for Eczema (HOME) initiative has identified quality of life (QoL) as a core outcome domain to be evaluated in every eczema trial. It is unclear which of the existing QoL instruments is most appropriate for this domain. Thus, the aim of this review was to systematically assess the measurement properties of existing measurement instruments developed and/or validated for the measurement of QoL in adult eczema. We conducted a systematic literature search in PubMed and Embase identifying studies on measurement properties of adult eczema QoL instruments. For all eligible studies, we assessed the adequacy of the measurement properties and the methodological quality with the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. A best evidence synthesis summarizing findings from different studies was the basis to assign four degrees of recommendation (A-D). A total of 15 articles reporting on 17 instruments were included. No instrument fulfilled the criteria for category A. Six instruments were placed in category B, meaning that they have the potential to be recommended depending on the results of further validation studies. Three instruments had poor adequacy in at least one required adequacy criterion and were therefore put in category C. The remaining eight instruments were minimally validated and were thus placed in category D. Currently, no QoL instrument can be recommended for use in adult eczema. The Quality of Life Index for Atopic Dermatitis (QoLIAD) and the Dermatology Life Quality Index (DLQI) are recommended for further validation research. © 2015 John Wiley & Sons A/S.

    To identify opportunities within nationally representative surveys and surveillance systems to measure indicators of sexual health, we reviewed and inventoried existing data systems that include variables relevant to sexual health. We searched for U.S. nationally representative surveys and surveillance systems that provided individual-level sexual health data. We assessed the methods of each data system and catalogued them by their measurement of the following domains of sexual health: knowledge, communication, attitudes, service access and utilization, sexual behaviors, relationships, and adverse health outcomes. We identified 18 U.S.-focused, nationally representative data systems: six assessing the general population, seven focused on special populations, and five addressing health outcomes. While these data systems provide a rich repository of information from which to assess national measures of sexual health, they present several limitations. Most importantly, apart from data on service utilization, routinely gathered, national data are currently focused primarily on negative aspects of sexual health (e.g., risk behaviors and adverse health outcomes) rather than more positive attributes (e.g., healthy communication and attitudes, and relationship quality). Nationally representative data systems provide opportunities to measure a broad array of domains of sexual health. However, current measurement gaps indicate the need to modify existing surveys, where feasible and appropriate, and develop new tools to include additional indicators that address positive domains of sexual health of the U.S. population across the life span. Such data can inform the development of effective policy actions, services, prevention programs, and resource allocation to advance sexual health.

  4. Cumulative sum quality control for calibrated breast density measurements

    Heine, John J.; Cao Ke; Beam, Craig

    2009-01-01

    Purpose: Breast density is a significant breast cancer risk factor. Although various methods are used to estimate breast density, there is no standard measurement for this important factor. The authors are developing a breast density standardization method for use in full field digital mammography (FFDM). The approach calibrates for interpatient acquisition technique differences. The calibration produces a normalized breast density pixel value scale. The method relies on first generating a baseline (BL) calibration dataset, which required extensive phantom imaging. Standardizing prospective mammograms with calibration data generated in the past could introduce unanticipated error in the standardized output if the calibration dataset is no longer valid. Methods: Sample points from the BL calibration dataset were imaged approximately biweekly over an extended timeframe. These serial samples were used to evaluate the BL dataset reproducibility and quantify the serial calibration accuracy. The cumulative sum (Cusum) quality control method was used to evaluate the serial sampling. Results: There is considerable drift in the serial sample points from the BL calibration dataset that is x-ray beam dependent. Systematic deviation from the BL dataset caused significant calibration errors. This system drift was not captured with routine system quality control measures. Cusum analysis indicated that the drift is a sign of system wear and eventual x-ray tube failure. Conclusions: The BL calibration dataset must be monitored and periodically updated, when necessary, to account for sustained system variations to maintain the calibration accuracy.

    Full Text Available Abstract Background: We aimed to: (i assess compliance with a new smokefree law in a range of hospitality settings; and (ii to assess the impact of the new law by measuring air quality and making comparisons with air quality in outdoor smoking areas and with international data from hospitality settings. Methods: We included 34 pubs, restaurants and bars, 10 transportation settings, nine other indoor settings, six outdoor smoking areas of bars and restaurants, and six other outdoor settings. These were selected using a mix of random, convenience and purposeful sampling. The number of lit cigarettes among occupants at defined time points in each venue was observed and a portable real-time aerosol monitor was used to measure fine particulate levels (PM2.5. Results: No smoking was observed during the data collection periods among over 3785 people present in the indoor venues, nor in any of the transportation settings. The levels of fine particulates were relatively low inside the bars, pubs and restaurants in the urban and rural settings (mean 30-minute level = 16 μg/m3 for 34 venues; range of mean levels for each category: 13 μg/m3 to 22 μg/m3. The results for other smokefree indoor settings (shops, offices etc and for smokefree transportation settings (eg, buses, trains, etc were even lower. However, some "outdoor" smoking areas attached to bars/restaurants had high levels of fine particulates, especially those that were partly enclosed (eg, up to a 30-minute mean value of 182 μg/m3 and a peak of maximum value of 284 μg/m3. The latter are far above WHO guideline levels for 24-hour exposure (ie, 25μg/m3. Conclusion: There was very high compliance with the new national smokefree law and this was also reflected by the relatively good indoor air quality in hospitality settings (compared to the "outdoor" smoking areas and the comparable settings in countries that permit indoor smoking.

    The transport of neonatal and pediatric patients to tertiary care facilities for specialized care demands monitoring the quality of care delivered during transport and its impact on patient outcomes. In 2011, pediatric transport teams in Ohio met to identify quality indicators permitting comparisons among programs. However, no set of national consensus quality metrics exists for benchmarking transport teams. The aim of this project was to achieve national consensus on appropriate neonatal and pediatric transport quality metrics. Modified Delphi technique. The first round of consensus determination was via electronic mail survey, followed by rounds of consensus determination in-person at the American Academy of Pediatrics Section on Transport Medicine's 2012 Quality Metrics Summit. All attendees of the American Academy of Pediatrics Section on Transport Medicine Quality Metrics Summit, conducted on October 21-23, 2012, in New Orleans, LA, were eligible to participate. Candidate quality metrics were identified through literature review and those metrics currently tracked by participating programs. Participants were asked in a series of rounds to identify "very important" quality metrics for transport. It was determined a priori that consensus on a metric's importance was achieved when at least 70% of respondents were in agreement. This is consistent with other Delphi studies. Eighty-two candidate metrics were considered initially. Ultimately, 12 metrics achieved consensus as "very important" to transport. These include metrics related to airway management, team mobilization time, patient and crew injuries, and adverse patient care events. Definitions were assigned to the 12 metrics to facilitate uniform data tracking among programs. The authors succeeded in achieving consensus among a diverse group of national transport experts on 12 core neonatal and pediatric transport quality metrics. We propose that transport teams across the country use these metrics to

    Previous work has compared marital quality between stably married and divorced individuals. Less work has examined the possibility of variation among divorcés in trajectories of marital quality as divorce approaches. This study addressed that hole by first examining whether distinct trajectories of marital quality can be discerned among women whose marriages ended in divorce and, second, the profile of women who experienced each trajectory. Latent class growth analyses with longitudinal data from a nationally representative sample were used to "look backward" from the time of divorce. Although demographic and socioeconomic variables from this national sample did not predict the trajectories well, nearly 66% of divorced women reported relatively high levels of both happiness and communication and either low or moderate levels of conflict. Future research including personality or interactional patterns may lead to theoretical insights about patterns of marital quality in the years leading to divorce.

    National Water Summary 1990-91 Hydrologic Events and Stream Water Quality was planned to complement existing Federal-State water-quality reporting to the U.S. Congress that is required by the Clean Water Act of 1972. This act, formally known as the Federal Water Pollution Control Act Amendments of 1972 (Public Law 92-500), and its amendments in 1977,1979,1980,1981,1983, and 1987, is the principal basis for Federal-State cooperation on maintaining and reporting on water quality in the United States. Under section 305(b) of the Clean Water Act, the States must designate uses for waterbodies, biennially assess whether the waterbodies meet designated uses, and report to the U.S. Environmental Protection Agency (EPA), which in turn summarizes the findings of the State assessments in a biennial National Water Quality Inventory report to the Congress.

    During the period of 10th five-year plan, MEP has constructed a national radiation environmental monitoring network. In the running of the network, quality management on monitoring data is of vital importance. So all the members of the radiation environmental monitoring network are required to ensure the quality of monitoring method, equipment, reagent,quality of personnel, data processing and information management and so on. Thus the monitoring result would be typical and accuracy in science. The article introduced in detail the quality management status of the National Radiation Environmental Monitoring Network and put forward the strategy for development from the institutionalized and large-scale point of view of radioactive environmental monitoring work.

    Ensuring that artemisinin-containing antimalarials (ACAs) are of good quality is a key component of effective malaria treatment. There are concerns that a high proportion of ACAs are falsified or substandard, though estimates are rarely based on representative data. During a nationally representative survey in Tanzania, ACAs were purchased from private retail drug outlets, and the active pharmaceutical ingredient (API) was measured. All 1,737 ACAs contained the labeled artemisinin derivative, with 4.1% being outside the 85-115% artemisinin API range defined as acceptable quality. World Health Organization (WHO) prequalified drugs had 0.1 times the odds of being poor quality compared with non-prequalified ACAs for the artemisinin component. When partner components of combination therapies were also considered, 12.1% were outside the acceptable API range, and WHO prequalified ACAs had 0.04 times the odds of being poor quality. Although the prevalence of poor quality ACAs was lower than reported elsewhere, the minority of samples found to be substandard is a cause for concern. Improvements in quality could be achieved by increasing the predominance of WHO prequalified products in the market. Continued monitoring of quality standards is essential. © The American Society of Tropical Medicine and Hygiene.

    Lack of funding and lack of focus on research over the past several years, coupled with force measurement capabilities being decentralized and distributed across the National Aeronautics and Space Administration (NASA) research centers, has resulted in a significant erosion of (1) capability and infrastructure to produce and calibrate force measurement systems; (2) NASA s working knowledge of those systems; and (3) the quantity of high-quality, full-capability force measurement systems available for use in aeronautics testing. Simultaneously, and at proportional rates, the capability of industry to design, manufacture, and calibrate these test instruments has been eroding primarily because of a lack of investment by the aeronautics community. Technical expertise in this technology area is a core competency in aeronautics testing; it is highly specialized and experience-based, and it represents a niche market for only a few small precision instrument shops in the United States. With this backdrop, NASA s Aeronautics Test Program (ATP) chartered a team to examine the issues and risks associated with the problem, focusing specifically on strain- gage balances. The team partnered with the U.S. Air Force s Arnold Engineering Development Center (AEDC) to exploit their combined capabilities and take a national level government view of the problem. This paper describes the team s approach, its findings, and its recommendations, and the current status for revitalizing the government s balance capability with respect to designing, fabricating, calibrating, and using the instruments.

    We develop a framework for analyzing national income accounting using a revealed welfare approach that is sufficiently general to cover, e.g., both the standard discounted utilitarian and maximin criteria as special cases. We show that the basic welfare properties of comprehensive national income accounting, which were previously ascribed only to the discounted utilitarian case, in fact extend to this more general framework. In particular, it holds under a wide range of circumstances that rea...

    Full Text Available Abstract Background The Democratic National Convention (DNC in Boston, Massachusetts in 2004 provided an opportunity to evaluate the impacts of a localized and short-term but potentially significant change in traffic patterns on air quality, and to determine the optimal monitoring approach to address events of this nature. It was anticipated that the road closures associated with the DNC would both influence the overall air pollution level and the distribution of concentrations across the city, through shifts in traffic patterns. Methods To capture these effects, we placed passive nitrogen dioxide badges at 40 sites around metropolitan Boston before, during, and after the DNC, with the goal of capturing the array of hypothesized impacts. In addition, we continuously measured elemental carbon at three sites, and gathered continuous air pollution data from US EPA fixed-site monitors and traffic count data from the Massachusetts Highway Department. Results There were significant reductions in traffic volume on the highway with closures north of Boston, with relatively little change along other highways, indicating a more isolated traffic reduction rather than an across-the-board decrease. For our nitrogen dioxide samples, while there was a relatively small change in mean concentrations, there was significant heterogeneity across sites, which corresponded with our a priori classifications of road segments. The median ratio of nitrogen dioxide concentrations during the DNC relative to non-DNC sampling periods was 0.58 at sites with hypothesized traffic reductions, versus 0.88 for sites with no changes hypothesized and 1.15 for sites with hypothesized traffic increases. Continuous monitors measured slightly lower concentrations of elemental carbon and nitrogen dioxide during road closure periods at monitors proximate to closed highway segments, but not for PM2.5 or further from major highways. Conclusion We conclude that there was a small but

    Full Text Available Background : Rivers are a fraction of flowing waters in the worlds and one of the important sources of water for different consumptions such as agricultural, drinking and industrial uses. The aim of this study was to assess water quality of the Khorramrood River in Khorramabad by NSFWQI index. Materials and Methods: In this cross-sectional study, quality parameters needed for NASWQI index calculation such as BOD5, dissolved oxygen (DO, total nitrate, fecal coliform, pH, total phosphate, temperature, turbidity and total suspended solids content were measured for six months (from July to December 2012using standard methods at six selected stations. The river zoning conducted by GIS software. Results: According to the results obtained through this study, the highest and the lowest water quality value was observed in stations 1 and 6 with NSFWQI indexes 82 water with good quality, 42 water with bad quality, respectively. With moving toward last station (from 1 to 6 station water pollution increased. Conclusion: Results of the study indicated that water quality index NSFWQI is a good index to identify the effect of polluter sources on the river water. Based on the average of the index NSFWQI, water quality in station one was good, in the second, third and fourth stations were mediocre and the fifth and sixth stations had bad quality. These results allow to make decisions about monitoring and controlling water pollution sources, as well as provide different efficient uses of it by relevant authorities.

    The U.S. Geological Survey Branch of Quality Systems operates the Precipitation Chemistry Quality Assurance project (PCQA) to provide independent, external quality-assurance for the National Atmospheric Deposition Program (NADP). NADP is composed of five monitoring networks that measure the chemical composition of precipitation and ambient air. PCQA and the NADP Program Office completed five short-term studies to investigate the effects of equipment performance with respect to the National Trends Network (NTN) and Mercury Deposition Network (MDN) data quality: sample evaporation from NTN collectors; sample volume and mercury loss from MDN collectors; mercury adsorption to MDN collector glassware, grid-type precipitation sensors for precipitation collectors, and the effects of an NTN collector wind shield on sample catch efficiency. Sample-volume evaporation from an NTN Aerochem Metrics (ACM) collector ranged between 1.1–33 percent with a median of 4.7 percent. The results suggest that weekly NTN sample evaporation is small relative to sample volume. MDN sample evaporation occurs predominantly in western and southern regions of the United States (U.S.) and more frequently with modified ACM collectors than with N-CON Systems Inc. collectors due to differences in airflow through the collectors. Variations in mercury concentrations, measured to be as high as 47.5 percent per week with a median of 5 percent, are associated with MDN sample-volume loss. Small amounts of mercury are also lost from MDN samples by adsorption to collector glassware irrespective of collector type. MDN 11-grid sensors were found to open collectors sooner, keep them open longer, and cause fewer lid cycles than NTN 7-grid sensors. Wind shielding an NTN ACM collector resulted in collection of larger quantities of precipitation while also preserving sample integrity.

    Full Text Available An adequate supply of safe drinking water is one of major ways to obtain healthy life. Water filter system is one way to improve the water quality. However, to maintain the performance of the system, it need to undergo the maintenance service. This study evaluate the requirement of maintenance service in water filter system. Water quality was measured before and after maintenance service. Parameters measured were pH, turbidity, residual chlorine, nitrate and heavy metals and these parameters were compared with National Drinking Water Quality Standards. Collection of data were involved three housing areas in Johor. The quality of drinking water from water filter system were analysed using pH meter, turbidity meter, DR6000 and Inductively Coupled Plasma-Mass Spectrometer. pH value was increased from 16.4% for before maintenance services to 30.7% for after maintenance service. Increment of removal percentage for turbidity, residual chlorine and nitrate after maintenance were 21.5, 13.6 and 26.7, respectively. This result shows that maintenance service enhance the performance of the system. However, less significant of maintenance service for enhance the removal of heavy metals which the increment of removal percentage in range 0.3 to 9.8. Only aluminium shows percentage removal for after maintenance with 92.8% lower compared to before maintenance service with 95.5%.

    Several attempts have been made to assess the damage induced in materials by crystal orientation distributions identified using electron backscatter diffraction (EBSD). In particular, the local misorientation, which is the misorientation between neighboring measurement points, was shown to correlate well with the degree of material damage such as plastic strain, fatigue and creep. However, the damage assessments conducted using the local misorientations were qualitative rather than quantitative. The local misorientation can be correlated theoretically with physical parameters such as dislocation density. However, the error in crystal orientation measurements makes quantitative evaluation of the local misorientation difficult. Furthermore, the local misorientation depends on distance between the measurement points (step size). For a quantitative assessment of the local misorientation, the error in the crystal orientation measurements must be reduced or the degree of error must be shown quantitatively. In this study, first, the influence of the quality of measurements (accuracy of measurements) and step size on the local misorientation was investigated using stainless steel specimens damaged by tensile deformation or fatigue. By performing the crystal orientation measurements with different conditions, it was shown that the quality of measurement could be represented by the error index, which was previously proposed by the author. Secondly, a filtering process was applied in order to improve the accuracy of crystal orientation measurements and its effect was investigated using the error index. It was revealed that the local misorientations obtained under different measurement conditions could be compared quantitatively only when the error index and the step size were almost or exactly the same. It was also shown that the filtering process could successfully reduce the measurement error and step size dependency of the local misorientations. By applying the filtering

    With the advent of large-scale protein interaction studies, there is much debate about data quality. Can different noise levels in the measurements be assessed by analyzing network structure? Because proteomic regulation is inherently co-operative, modular and redundant, it is inherently compressible when represented as a network. Here we propose that network compression can be used to compare false positive and false negative noise levels in protein interaction networks. We validate this hypothesis by first confirming the detrimental effect of false positives and false negatives. Second, we show that gold standard networks are more compressible. Third, we show that compressibility correlates with co-expression, co-localization, and shared function. Fourth, we also observe correlation with better protein tagging methods, physiological expression in contrast to over-expression of tagged proteins, and smart pooling approaches for yeast two-hybrid screens. Overall, this new measure is a proxy for both sensitivity and specificity and gives complementary information to standard measures such as average degree and clustering coefficients. PMID:22719828

    1997-01-01

    This Transuranic (TRU) Waste Quality Assurance Project Plan (QAPjP) serves as the quality management plan for the characterization of transuranic waste in preparation for certification and transportation. The Transuranic Waste Characterization/Certification Program (TWCP) consists of personnel who sample and analyze waste, validate and report data; and provide project management, quality assurance, audit and assessment, and records management support, all in accordance with established requirements for disposal of TRU waste at the Waste Isolation Pilot Plant (WIPP) facility. This QAPjP addresses how the TWCP meets the quality requirements of the Carlsbad Area Office (CAO) Quality Assurance Program Description (QAPD) and the technical requirements of the Transuranic Waste Characterization Quality Assurance Program Plan (QAPP). The TWCP characterizes and certifies retrievably stored and newly generated TRU waste using the waste selection, testing, sampling, and analytical techniques and data quality objectives (DQOs) described in the QAPP, the Los Alamos National Laboratory Transuranic Waste Certification Plan (Certification Plan), and the CST Waste Management Facilities Waste Acceptance Criteria and Certification [Los Alamos National Laboratory (LANL) Waste Acceptance Criteria (WAC)]. At the present, the TWCP does not address remote-handled (RH) waste

    It is important to check periodically the quality and quantity of the X-rays emitted, in order to obtain the best possible performance from your diagnostic X-ray apparatus. The best way of checking the exact quality of the X-ray is to measure the spectrum of the X-ray, but it is not an easy task to carry out. The second way is to plot the attenuation curve of the X-rays. We have developed a method to plot the attenuation curve by a single exposure, utilizing J.r. Greening's empirical formula. The output of the three cavity ionization chambers, one with 7 mmAl filter, another with a 3 mmAl and the third without any filter, exposed to the same X-ray, were put into a microcomputer. The programming was arranged to display the attenuation curve of the X-rays, effective energy of the X-rays, the 1st HVL and the 2nd HVL on the CRT. The attenuation curves of the X-rays, emitted at a tube voltage at between 60 and 140 kV obtained by this method, agreed with the experimental results with an error of +-4 %. The effective energy obtained by this method agreed with the experimental data with an error of +-1 %. (author)

    SERVPEFR, the performance component of the Service Quality Scale (SERVQUAL), has been shown to measure five underlying dimensions corresponding to Tangibles, Reliability, Responsiveness, Assurance, and Empathy (Parasuraman, Zeithaml, & Berry, 1988). This paper describes three separate studies employing SERVPERF in an Australian context. In the first of these studies (N = 113), a shortened 15-item version of the SERVPERF scale (SERVPERF-R) was found to be suitable for use in an Australian small business setting. A five-factor structure was identifiable but the factors were highly correlated, suggesting that they were not clearly distinct. The tendency for marked negative skewness observed by other researchers was also noted here. A follow-up study involving three other small businesses (N = 212) used Rasch analysis to test assumptions about the spread of items on the underlying continuum. These analyses indicated that there is an even, though narrow, spread of items across the continuum. The Rasch analysis suggested that the items in both SERVPERF and SERVPERF-R are too easy to rate highly and that more "difficult" items need to be added to the scale. The third study (N = 122) was conducted using a version of SERVPERF-R that included seven new items intended to extend the range of the scale. The new items, however, did not achieve this desirable outcome. The implications for service quality assessment are discussed.

    The increase in large-scale planning activities and their realization in all fields of quality testing as opposed to the requirements for a reduction of costs emphasizes the necessity of rationaling measures. Especially during the planning phases there are a number of possibilities for solving this problem: the determination of reference dates for production devices based on the preparation of dates with regard to machines and testing, the assignment of the testing frequency in dependence of the quotient from deviations in production and characteristics tolerances, the application of methods of operation planning following different priority rules. Apart from already existing systems for normal and computeraided planning of testing material application by the help of which the most optimal testing material is selected for certain testing jobs systematic representations and programs for the planning of the testing procedure and the testing precision will enrich the joint complex of the organization of testing procedures.
