    2015-01-01

    This article explores the importance of quality practices in underpinning the person-centred approach at a Community Options Program (COP) case management service in northern NSW. The NSW community care sector does not have a statutory excellence body to identify, promote and support improved practices and quality and safety across community services, and therefore the COP provider decided to establish a dedicated role to focus on the quality improvement of its service. The subsequent quality improvement initiatives have included mapping the clients' journey through the service, identifying areas to standardise practice, and creating service pathways. The clients' journey was used as the framework to identify where standardised practice was required, and a robust process was implemented to develop over 25 good practice guidelines and tools that addressed the variations in practice and enabled the service pathways to be developed. Prior to trialling the guidelines and tools, staff received education sessions on the anticipated changes to practice, and the practicality and applicability of the guidelines were evaluated at the end of the trials. This information was reviewed and the guidelines were amended accordingly before being rolled out. The guidelines have been in use for over 12 months and have provided the benchmark against which to audit practice, and have resulted in key performance improvements such as an increase in client review rates and a rise in the feedback response rate from clients, with a noticeable shift in the comments about the brokered support worker to acknowledging the role of their case manager. Formalising informal supports for those clients that lived alone also increased, which means these people are less reliant on services and there is a reduced risk of social isolation. PMID:24598416

  2. Total Quality Project Initiatives and Fabrication Improvements at ENUSA Factory

    International Nuclear Information System (INIS)

    ENUSA is committed to maximize fuel reliability through different improvement programs to cover fabrication processes, inspection techniques benchmarking with different partners and total quality projects. All these programs focus on reliability of product trough three main concepts: quality as a priority, continuous improvement and personnel involvement in their work. This brief paper describes the Cero defects program, which goal is to obtain a factor of 10 improvement and approach the value of 1/1.000.000 or 1 ppm. A task force was formed to review all aspects relating to fuel rod hermeticity (component suppliers methods, welding techniques, end plugs design, tubes certifications, etc.). Another Best Practices Task Force was formed to review all aspects of pellets manufacturing. Recommendations are then summarized

    Full Text Available Abstract Background Despite major policy initiatives in the United Kingdom to enhance women's experiences of maternity care, improving in-patient postnatal care remains a low priority, although it is an aspect of care consistently rated as poor by women. As part of a systems and process approach to improving care at one maternity unit in the South of England, the views and perspectives of midwives responsible for implementing change were sought. Methods A Continuous Quality Improvement (CQI approach was adopted to support a systems and process change to in-patient care and care on transfer home in a large district general hospital with around 6000 births a year. The CQI approach included an initial assessment to identify where revisions to routine systems and processes were required, developing, implementing and evaluating revisions to the content and documentation of care in hospital and on transfer home, and training workshops for midwives and other maternity staff responsible for implementing changes. To assess midwifery views of the quality improvement process and their engagement with this, questionnaires were sent to those who had participated at the outset. Results Questionnaires were received from 68 (46% of the estimated 149 midwives eligible to complete the questionnaire. All midwives were aware of the revisions introduced, and two-thirds felt these were more appropriate to meet the women's physical and emotional health, information and support needs. Some midwives considered that the introduction of new maternal postnatal records increased their workload, mainly as a consequence of colleagues not completing documentation as required. Conclusions This was the first UK study to undertake a review of in-patient postnatal services. Involvement of midwives at the outset was essential to the success of the initiative. Midwives play a lead role in the planning and organisation of in-patient postnatal care and it was important to obtain their feedback on whether revisions were pragmatic and achieved anticipated improvements in care quality. Their initial involvement ensured priority areas for change were identified and implemented. Their subsequent feedback highlighted further important areas to address as part of CQI to ensure best quality care continues to be implemented. Our findings could support other maternity service organisations to optimise in-patient postnatal services.

    Reliable delivery of optimal care can be challenging for care providers. Health care leaders have integrated various business tools to assist them and their teams in ensuring consistent delivery of safe and top-quality care. The cornerstone to all quality improvement strategies is the detailed understanding of the current state of a process, captured by process mapping. Process mapping empowers caregivers to audit how they are currently delivering care to subsequently strategically plan improvement initiatives. As a community, neurosurgery has clearly shown dedication to enhancing patient safety and delivering quality care. A care redesign strategy named NERVS (Neurosurgery Enhanced Recovery after surgery, Value, and Safety) is currently being developed and piloted within our department. Through this initiative, a multidisciplinary team led by a clinician neurosurgeon has process mapped the way care is currently being delivered throughout the entire episode of care. Neurosurgeons are becoming leaders in quality programs, and their education on the quality improvement strategies and tools is essential. The authors present a comprehensive review of process mapping, demystifying its planning, its building, and its analysis. The particularities of using process maps, initially a business tool, in the health care arena are discussed, and their specific use in an academic neurosurgical department is presented.

    In this article, we describe how teachers in the Australian school system are educated to teach science and the different qualifications that teachers need to enter the profession. The latest comparisons of Australian students in international science assessments have brought about various accountability measures to improve the quality of science teachers at all levels. We discuss the issues and implications of government initiatives in preservice and early career teacher education programs, such as the implementation of national science curriculum, the stricter entry requirements to teacher education programs, an alternative pathway to teaching and the measure of effectiveness of teacher education programs. The politicized discussion and initiatives to improve the quality of science teacher education in Australia are still unfolding as we write in 2014.

    2014-09-01

    Full Text Available Background: Pediatric subspecialists can participate in the care of obese children. Objective: To describe steps to help subspecialty providers initiate quality improvement efforts in obesity care. Methods: An anonymous patient data download, provider surveys and interviews assessed subspecialty providers’ identification and perspectives of childhood obesity and gathered information on perceived roles and care strategies. Participating divisions received summary analyses of quantitative and qualitative data and met with study leaders to develop visions for division/service-specific care improvement. Results: Among 13 divisions/services, subspecialists’ perceived role varied by specialty; many expressed the need for cross-collaboration. All survey informants agreed that identification was the first step, and expressed interest in obtaining additional resources to improve care. Conclusions: Subspecialists were interested in improving the quality and coordination of obesity care for patients across our tertiary care setting. Developing quality improvement projects to achieve greater pediatric obesity care goals starts with engagement of providers toward better identifying and managing childhood obesity.

    The aim of this quality improvement initiative was to incorporate a paediatric early warning score (PEWS) and track and trigger system in the routine care of children in an acute general children's ward at a regional hospital in the Republic of Ireland. In the absence of a nationally recommended specific PEWS strategy, a local plan was developed. The experience of structuring and implementing the PEWS and track and trigger system is presented in this article. Data from the first year of use were collected to evaluate the clinical utility and effectiveness of this system. In the busy acute children's service, the PEWS initiative was found to benefit processes of early detection, prompt referral and timely, appropriate management of children at potential risk of clinical deterioration. Nursing staff were empowered and supported to communicate concerns immediately and to seek rapid medical review, according to an agreed PEWS escalation plan. Outcomes were significantly improved.

  12. Application of quality-improvement methods in a community practice: the Sandhills Pediatrics Asthma Initiative.

    Wroth, Thomas H; Boals, Joseph C

    2005-01-01

    This case study demonstrates the use of quality improvement methods to improve asthma care in a busy community practice. The practice used disease-management strategies, such as population identification, self-management education, and performance measurement and feedback. The practice then applied several practice-based quality improvement methods, such as PDSA cycles, to improve care. From 1998 to 2003, process measures, such as staging of asthmatics, use of long-term control medications, use of peak flow meters and spacers, and use of action plans, improved. There was also a substantial decrease in emergency department use and hospitalizations among patients with asthma. Although there have been several studies demonstrating the efficacy of disease management strategies, most lack generalizability to community practices. Often, interventions are so intensive and cumbersome, that they are unlikely to be replicated in primary care setting. Researchers have been unable to determine which components of the interventions are most effective and replicable. Furthermore, many studies of disease management strategies enroll participants who lack the co-morbidities seen in community practice. There are also few studies of disadvantaged populations that face other barriers to care, such as lack of transportation, poor access to specialists, and medical illiteracy. In this case study, there were several unique factors that enabled the practice to improve care for this population. The AccessCare case manager who worked with the practice not only provided data and feedback to the practice team, but also served as an improvement "coach," often pushing the team and facilitating many of the improvement efforts. AccessCare's approach is in contrast to many of the commercial disease management companies' "carve out" models that do not sufficiently involve providers or practices in their interventions. The other necessary ingredient for success in this project was organizational leadership and support. The leaders of the practice saw beyond the usual metrics of patient visit counts and relative value units (RVUs) to embrace the concept of population health: the notion that practices are not only responsible for providing acute, episodic care in the office, but also for improving health outcomes in the community in which they serve. Other important factors included ensuring a basic agreement among providers on the need for improvement and frequent communication about the goals of the project. Although the champions of the project tried to minimize formal meeting time, there was frequent informal communication between team members. In the future, there is a need to develop other approaches to stimulate these endeavors in community practices, such as "pay for performance" programs, continuing education credit, and tying maintenance of board certification to quality improvement initiatives.

    Seymour, D W; Guillett, W V

    1997-09-01

    Discuss cost management and performance improvement with any manager at an acute care hospital and you will hear several consistent themes: Quality improvement (QI) has not produced the anticipated results on a timely basis; Focused cost reduction efforts have at best provided short-term benefits; and The organization needs to be more nimble, more responsive to the marketplace. If your hospital is wrestling with these issues, take some comfort in knowing that you are not alone. In general, the same problems are being experienced by long-term care facilities, group practices, practice plans, and most other provider organizations. However, all is not doom and gloom. A common-sense, easy-to-understand solution to the cost control problem can be implemented if an organization is disciplined and can exercise patience and diligence in implementation. Business Process Redesign (BPR), a performance improvement strategy and tactic that has been successfully deployed throughout private industry, can solve the problem. If undertaken correctly, BPR links the best concepts and principles of quality improvement, operations analysis, and focused cost reduction with an organization's strategic planning efforts. BPR results in the establishment of cost management initiatives that are consistent with the organization's long term goals. This article takes a closer look at the merits of BPR in a changing healthcare environment. PMID:10173840

    Quality improvement is a leading approach to the difficult yet inevitable task of managing organizational change. The literature suggests that facilitators can help organizations apply improvement principles and tools but it is unclear how facilitators actually do this and how they develop their own skills. Using a case study design we therefore examined how facilitators worked with 93 improvement projects in over 1000 sessions at one Swedish university hospital where systematic process improvement was successfully established over a 5-year period. They facilitated improvement by providing a framework and methods' support for improvement efforts--relying on experiential learning rather than didactic teaching--while letting clinical teams and managers maintain control over the content of improvement projects. They developed extensive experience that they documented and could transfer between teams, so that each team could benefit from lessons learned elsewhere. They improved facilitation through participant feedback and systematic review and reflection regarding their own practice. We suggest that facilitators can help organizations manage change by assuming responsibility for demanding tasks related to improvement work, developing specialized skill and extensive experience regarding improvement, and transferring insights across the organization, while using a learning approach throughout including to their own work.

    2008-01-01

    This article describes an innovative asthma quality improvement initiative conducted in school-based health centers (SBHCs) with collaboration among multiple community partners including the children's hospital, a federally qualified health center, the health department, the public school, and parents of children with asthma. The aim was to improve the health of children with asthma in these schools, as measured by minimal asthma-related activity restriction and reduction in asthma-related emergency department (ED) visits. Process measures tracked included the percent of children with (1) asthma severity classified, (2) persistent asthma with controller medication prescribed, and (3) written care plans. Data supported a statistically significant decreasing trend for the percent of SBHC children reporting activity restriction due to asthma. In addition, trend analysis demonstrated a statistically significant difference in ED visits for asthma in the SBHC group compared with a non-SBHC group. Improvements were demonstrated for all process measures. Factors contributing to success included emphasis on community engagement, transparency in sharing ideas and results, benefits outweighing human resource costs of participating, readily available data to drive improvement, and the use of multiple intervention strategies.

    Full Text Available Hearing loss present from birth can have a detrimental impact on later language and educational outcomes. Newborn hearing screening has allowed early identification and intervention of hearing loss, giving children the opportunity to develop age-appropriate language skills. The aim of this quality initiative study was to evaluate the quality of the newborn hearing screening program in the context of a newly implemented Baby-Friendly Hospital Initiative Program at Summa Health System Akron City Hospital. The goals were (1 to determine whether screening environment (mother’s room vs. nursery affected screening results, (2 to identify challenges and positive outcomes encountered by the audiologists, and (3 to ensure that Pass/Refer rates met state standards. A Quest Technologies sound level meter (Model 1800; St. Paul, MN, USA was used to measure noise levels in the nursery rooms where newborns were tested. The length of screening time was determined using a calibrated SP® Traceable® (ISO 17025 stopwatch (McGraw Park, IL, USA. Pass/Refer rates and observed challenges and benefits were noted. All well-baby infants born in the month of February 2013 (n = 101 were included, and Pass/Refer results were compared to those in years 2008-2012.Noise levels in the mother’s room did not appear to negatively affect the Pass/Refer rates. Some challenges were present, including interruptions and louder environmental noise. This protocol was considered appropriate for assessing a hearing screening program in a Baby-Friendly Hospital Initiative (BFHI setting.Benefits of performing hearing screening in the mother’s room included test transparency for parents and the ability to immediately discuss the results. Results obtained in the mother’s room were comparable to past results obtained in the nursery. Noise levels in the screening rooms and challenges should be noted, to ensure accuracy of screening results.

    The "lean" approach is a quality improvement method that focuses on maximizing activities that are valued by the customer and eliminating waste that impedes efficiency in the workplace. The unique philosophy of the lean approach encourages all members of the team to be directly involved in identifying areas of waste and generating solutions to eliminate them. When the breast imaging section at the authors' institution became part of a multispecialty breast care center, the result was escalating examination volumes, more complex cases, and overall increased demand on radiologists' time. After several unsuccessful attempts to improve the efficiency of the section, including evaluation by outside consultants, the decision was made to embark on a comprehensive quality improvement program using the lean approach. A team of radiologists, technologists, file room personnel, information technology (IT) representatives, and administrators from the breast imaging section met twice a month to learn about lean principles and how to apply them to screening mammography workflows. Sources of inefficiency (waste) were identified, and potential solutions were generated. Multiple trials were performed to test these solutions. Throughout the process, all team members were engaged in identifying the problems, suggesting solutions, and implementing change. Most of the tested solutions were successful and resulted in decreased patient wait times, improved efficiency for the technologists and radiologists, faster report turnaround, and advances in IT. In addition, staff members were introduced to the lean philosophy and became actively involved in improving their workplace, resulting in a more cohesive section. PMID:23813321

    2014-10-01

    High quality equilibria are essential for extended-MHD modeling with the initial-value NIMROD code. Typically the spatial resolution requirements for extended-MHD modeling, which must resolve singular-layer physics and highly anisotropic diffusion, are more stringent than the resolution of equilibrium reconstructions from experimental discharges. With the current workflow, reconstructed fields are mapped onto the NIMROD finite-element grid, and the disparity between the coarse resolution reconstruction and the fine resolution FE grid can create artificial small-scale artifacts. Extended-MHD modeling, which contains many high-order differential operators, can be corrupted by the mapping errors. We describe efforts to re-solve the Grad-Shafranov equation with open-flux regions using the NIMEQ solver to generate a new equilibrium while using the mapped results for both an initial guess and to specify the boundary conditions. Effects on computations with and without the re-solving for force balance will be described. Work funded by US DOE.

    Many hospital radiology departments are adopting "lean" methods developed in automobile manufacturing to improve operational efficiency, eliminate waste, and optimize the value of their services. The lean approach, which emphasizes process analysis, has particular relevance to radiology departments, which depend on a smooth flow of patients and uninterrupted equipment function for efficient operation. However, the application of lean methods to isolated problems is not likely to improve overall efficiency or to produce a sustained improvement. Instead, the authors recommend a gradual but continuous and comprehensive "lean transformation" of work philosophy and workplace culture. Fundamental principles that must consistently be put into action to achieve such a transformation include equal involvement of and equal respect for all staff members, elimination of waste, standardization of work processes, improvement of flow in all processes, use of visual cues to communicate and inform, and use of specific tools to perform targeted data collection and analysis and to implement and guide change. Many categories of lean tools are available to facilitate these tasks: value stream mapping for visualizing the current state of a process and identifying activities that add no value; root cause analysis for determining the fundamental cause of a problem; team charters for planning, guiding, and communicating about change in a specific process; management dashboards for monitoring real-time developments; and a balanced scorecard for strategic oversight and planning in the areas of finance, customer service, internal operations, and staff development.

    2009-07-01

    Imaging services constitute a huge portion of the of the total dollar investment within the health care enterprise. Accordingly, this generates competition among medical specialties organized along service lines for their pieces of the pie and increased scrutiny from third-party payers and government regulators. These market and political forces create challenge and opportunity for a hospital-based radiology practice. Clearly, change that creates or builds greater value for patients also creates sustainable competitive advantage for a radiology practice. The somewhat amorphous concept of quality constitutes a significant value driver for innovation in this scenario. Quality initiatives and programs seek to define and manage this amorphous concept and provide tools for a radiology practice to create or build more value. Leadership and the early adoption of these inevitable programs by a radiology practice strengthens relationships with hospital partners and slows the attrition of imaging service lines to competitors.

  11. Improving quality: Industry perspective

    International Nuclear Information System (INIS)

    Since 1992, there have been a number of activities related to reviews of regulations and the regulatory process affecting utilities with operating nuclear power plants. The Nuclear Regulatory Commission (NRC) reviewed regulations to reduce the regulatory burden and initiated efforts to eliminate requirements marginal to safety. The NRC Chain-nan challenged the industry to identify specific areas where regulations or the regulatory process unnecessarily contributes to increased c without a commensurate safety benefits Additionally, the NRC published the Regulatory Review Group Report that contained a focused review of regulations and regulatory process, programs and practices for implementation. The culmination of these efforts has created a number of opportunities for regulatory improvement including utility licensee implementation of current regulations. One of the significant areas identified is the implementation of Quality Assurance within the framework of 10 CFR Part 50 Appendix B. Efforts are underway within the nuclear utility industry to develop a graded approach to implementation. This presents an opportunity for the nuclear utility industry to identify improvements that achieve efficiencies in the implementation of Quality Assurance Programs. The end result will be enhanced safety and flexibility in appropriate utilization of resources that are commensurate with the safety significance of the structure, system, or component (SSC)mponent (SSC)

    2010-10-01

    Full Text Available Abstract Background The Health Department of the Regional Government of Catalonia, Spain, issued a quality plan for substance abuse centers. The objective of this paper is to evaluate the impact of a multidimensional quality improvement initiative in the field of substance abuse care and to discuss potentials and limitations for further quality improvement. Methods The study uses an uncontrolled, sector-wide pre-post design. All centers providing services for persons with substance abuse issues in the Autonomous Community of Catalonia participated in this assessment. Measures of compliance were developed based on indicators reported in the literature and by broad stakeholder involvement. We compared pre-post differences in dimension-specific and overall compliance-scores using one-way ANOVA for repeated measures and the Friedman statistic. We described the spread of the data using the inter-quartile range and the Fligner-Killen statistic. Finally, we adjusted compliance scores for location and size using linear and logistic regression models. Results We performed a baseline and follow up assessment in 22 centers for substance abuse care and observed substantial and statistically significant improvements for overall compliance (pre: 60.9%; post: 79.1% and for compliance in the dimensions 'care pathway' (pre: 66.5%; post: 83.5% and 'organization and management' (pre: 50.5%; post: 77.2%. We observed improvements in the dimension 'environment and infrastructure' (pre: 81.8%; post: 95.5% and in the dimension 'relations and user rights' (pre: 66.5%; post: 72.5%; however, these were not statistically significant. The regression analysis suggests that improvements in compliance are positively influenced by being located in the Barcelona region in case of the dimension 'relations and user rights'. Conclusion The positive results of this quality improvement initiative are possibly associated with the successful involvement of stakeholders, the consciously constructed feedback reports on individual and sector-wide performance and the support of evidence-based guidance wherever possible. Further research should address how contextual issues shape the uptake and effectiveness of quality improvement actions and how such quality improvements can be sustained.

    Full Text Available Abstract Background Australia's Aboriginal and Torres Strait Islander (Indigenous populations have disproportionately high rates of adverse perinatal outcomes relative to other Australians. Poorer access to good quality maternal health care is a key driver of this disparity. The aim of this study was to describe patterns of delivery of maternity care and service gaps in primary care services in Australian Indigenous communities. Methods We undertook a cross-sectional baseline audit for a quality improvement intervention. Medical records of 535 women from 34 Indigenous community health centres in five regions (Top End of Northern Territory 13, Central Australia 2, Far West New South Wales 6, Western Australia 9, and North Queensland 4 were audited. The main outcome measures included: adherence to recommended protocols and procedures in the antenatal and postnatal periods including: clinical, laboratory and ultrasound investigations; screening for gestational diabetes and Group B Streptococcus; brief intervention/advice on health-related behaviours and risks; and follow up of identified health problems. Results The proportion of women presenting for their first antenatal visit in the first trimester ranged from 34% to 49% between regions; consequently, documentation of care early in pregnancy was poor. Overall, documentation of routine antenatal investigations and brief interventions/advice regarding health behaviours varied, and generally indicated that these services were underutilised. For example, 46% of known smokers received smoking cessation advice/counselling; 52% of all women received antenatal education and 51% had investigation for gestational diabetes. Overall, there was relatively good documentation of follow up of identified problems related to hypertension or diabetes, with over 70% of identified women being referred to a GP/Obstetrician. Conclusion Participating services had both strengths and weaknesses in the delivery of maternal health care. Increasing access to evidence-based screening and health information (most notably around smoking cessation were consistently identified as opportunities for improvement across services.

    Suboptimal medication prescribing for older adults has been described in a number of emergency department (ED) studies. Despite this, few studies have examined ED-targeted interventions aimed at reducing the use of potentially inappropriate medications (PIMs). Enhancing Quality of Prescribing Practices for Older Veterans Discharged from the ED (EQUiPPED) is an ongoing multicomponent, interdisciplinary quality improvement initiative in eight Department of Veterans Affairs EDs. The project aims to decrease the use of PIMs, as identified by the Beers criteria, prescribed to veterans aged 65 and older at the time of ED discharge. Interventions include provider education; informatics-based clinical decision support with electronic medical record-embedded geriatric pharmacy order sets and links to online geriatric content; and individual provider education including academic detailing, audit and feedback, and peer benchmarking. Poisson regression was used to compare the number of PIMs that staff providers prescribed to veterans aged 65 and older discharged from the ED before and after the initiation of the EQUiPPED intervention. Initial data from the first implementation site show that the average monthly proportion of PIMs that staff providers prescribed was 9.4 ± 1.5% before the intervention and 4.6 ± 1.0% after the initiation of EQUiPPED (relative risk = 0.48, 95% confidence interval = 0.40-0.59, P < .001). Preliminary evaluation demonstrated a significant and sustained reduction of ED-prescribed PIMs in older veterans after implementation of EQUiPPED. Longer follow-up and replication at collaborating sites would allow for an assessment of the effect on health outcomes and costs. PMID:25945692

    2014-09-01

    The purpose of this study was to better understand why change initiatives succeed or fail in long-term care organizations. Four case studies from Québec, Canada were contrasted retrospectively. A constipation and restraints program succeeded, while an incontinence and falls program failed. Successful programs were distinguished by the use of a change strategy that combined "let-it happen," "help-it happen," and "make-it happen" interventions to create senses of urgency, solidarity, intensity, and accumulation. These four active ingredients of the successful change strategies propelled their respective change processes forward to completion. This paper provides concrete examples of successful and unsuccessful combinations of "let-it happen," "help-it happen," and "make-it happen" change management interventions. Change managers (CM) can draw upon these examples to best tailor and energize change management strategies in their own organizations. PMID:24652889

    2013-01-01

    Full Text Available The aim of the study was to study about the impact of quality improvement strategy on creating a sustainable competitive advantage in the qualified managers. The current study was based on empirical approach. A random sample of quality improvement was drawn from seven organizations. A self administrated questionnaire was employed to collect the required data. A number of hypotheses were formulated for this purpose. This article attempts to explain the quality improvement by qualified managers by patterns of thinking. The importance of strategic, long-term policy and quality improvement is very clear to planners. Quality managers like to follow a similar and routine quality behavioral pattern. This paper reviews organizational quality improvement and quality measurement literature. For organizations to be quality improvement strategy, they had to improve their working environment and delegate their employees more authorities by qualified managers. However, this study concluded that the performance of the organization is highly affected by its quality improvement strategy and qualified manager's creativity.

However, contextual factors, such as team functioning, leadership, and organizational support, can vary significantly across teams and affect the level of implementation success. Yet, the science for measuring context is immature. The goal of this study is to validate measures from a short instrument tailored to track dynamic context and progress for a team-based quality improvement (QI intervention. Methods Design: Secondary cross-sectional and longitudinal analysis of data from a clustered randomized controlled trial (RCT of a team-based quality improvement intervention to reduce central line-associated bloodstream infection (CLABSI rates in intensive care units (ICUs. Setting: Forty-six ICUs located within 35 faith-based, not-for-profit community hospitals across 12 states in the U.S. Population: Team members participating in an ICU-based QI intervention. Measures: The primary measure is the Team Check-up Tool (TCT, an original instrument that assesses context and progress of a team-based QI intervention. The TCT is administered monthly. Validation measures include CLABSI rate, Team Functioning Survey (TFS and Practice Environment Scale (PES from the Nursing Work Index. Analysis: Temporal stability, responsiveness and validity of the TCT. Results We found evidence supporting the temporal stability, construct validity, and responsiveness of TCT measures of intervention activities, perceived group-level behaviors, and barriers to team progress. Conclusions The TCT demonstrates good measurement reliability, validity, and responsiveness. By having more validated measures on implementation context, researchers can more readily conduct rigorous studies to identify contextual variables linked to key intervention and patient outcomes and strengthen the evidence base on successful spread of efficacious team-based interventions. QI teams participating in an intervention should also find data from a validated tool useful for identifying opportunities to improve their own implementation.

    Full Text Available In 2012, Oman Heart Association (OHA published its own guidelines for the management of patients with unstable angina/non–ST-elevation myocardial infarction, the aim was not to be comprehensive but rather simplified and practical in order to reduce the gap between the long comprehensive guidelines and our actual practice. However, we still feel that the busy registrars and residents need simpler and direct clinical pathways or protocol to be used in the emergency departments, coronary care units and in the wards. Clinical pathways are now one of the main tools used to manage the quality in healthcare concerning the standardization of care processes. It has been shown that their implementation reduces the variability in clinical practice and improves outcomes in acute care.

  7. Patient surveys and quality improvement.

    1996-01-01

    Patient satisfaction may be the ultimate measure of quality but it is only part of the quality measurement and improvement equation. Customers may be good at telling you what needs fixing but they cannot be expected to tell you how to fix the problem. It is important to let patient satisfaction measures guide the focus of your process improvement efforts, but these efforts must include the appropriate process measurement tools. A customer-focused survey will be valid only if it emphasizes key quality characteristics (KQCs), as defined by patients. You'll need to develop a sampling plan that will produce useable data. The design of the questionnaire and the reliability of the survey tool are critical to using patient surveys for quality improvement (QI). Surveys that don't meet standard criteria have a greater potential for error. Another challenge is the report format and analysis that are used to understand the patient responses. Having an external benchmark is critical to accurate measurement in patient surveys. Comparative data can also help prioritize QI projects. In summary, a well designed patient survey system can identify key quality characteristics, determine which KQCs have the most impact, help prioritize QI efforts, and measure patients' satisfaction in a reliable manner.

  8. Continuous improvement of software quality

    International Nuclear Information System (INIS)

    The present report is the first Halden Work Report delivered from the OECD Halden Reactor Project's research activity on formal methods and software quality. Of particular concern in this activity is to reach a consensus between regulators, licensees and the nuclear industry on questions related to the effective, industrial use of formal methods. The report gives considerable attention to the importance of continuous improvement as a characteristic of a living software quality system, and to the need of providing a basis for software process/product quality integration. In particular, the report discusses these aspects from the perspectives of defect prevention, formal methods, Total Quality Management (TQM), and Bayesian Belief Nets. Another concern is to promote controlled experiments on the use of new methods, techniques, and tools. This is achieved partly by reviewing suggestions on the collection and experimental use of data, and by surveying a number of metrics believed to have some potential for comparison studies (author) (ml)

    For the solution of initial value ordinary differential equations by library quality solvers, such as the DEPAC collection in the SLATEC library, it is important to start off with a good initial step size in order for the procedure to produce a reliable and efficient solution numerically. A substantial improvement has been made in the starting step size algorithm which corrects a long standing deficiency. Specifically, initial step sizes many orders from optimal (arising from stiff problems with mixed zero and nonzero initial values of disparate sizes) are brought under control.

    Full Text Available Purpose: The pipeline production is one of major processes in shipbuilding industry. Quality improvement and risk assessment in this process can yield significant savings, both in terms of internal quality costs as well as in terms of customer satisfactions.Design/methodology/approach: Shipbuilding pipeline production quality improvement has been carried out by application of FMEA (Failure Mode and Effect Analysis method. For the successful implementation of FMEA method it is necessary to identify process failure modes or possibility of the appearance of non-compliance, as well as their possible causes. For qualitative analysis of key input variables of the process, in the paper is used Ishikawa diagram and p-chart.Findings: It is shown that proposed approach to risk assessment in shipbuilding pipeline production is applicable to real casa scenario. The analysis has identified the points in the process with the highest probability of occurrence of nonconformities, or the highest risk for error.Research limitations/implications: As the experimenting has been conducted in shipyard, within production process, research schedule must have been set in accordance with production pace. Also, due to character of production process the data collecting was adopted to the production plan in that particular moment.Practical implications: Dealing with causes of potential nonconformities in the process can significantly contribute to the reliability and robustness of the process. Corrective actions that have been taken based on results of analysis significantly contributed to the level of quality in the pipeline production process.Originality/value: The pepper is dealing with a well known method applied in different production environment that are mostly conservative in production approach. It was shown that successful application of proposed approach can yield benefits especially in improved quality of produced pipelines within shipbuilding industry.

  16. Total quality drives nuclear plant improvements

    International Nuclear Information System (INIS)

    Total quality (TQ) at Carolina Power and Light (CP and L) is fulfilling a 1985 vision of Sherwood H. Smith, Jr., CP and L's chairman, president, and chief executive officer. The TQ concept has provided a way for employees to align their creative energies toward meeting the business needs of the company. Throughout CP and L, TQ has been recognized as the vehicle for reducing operating costs and improving customer satisfaction. Within the nuclear organization, application of the TQ process has helped to improve communications, resolve challenges, and provide more consistent work practices among CP and L's three nuclear plants. Total quality was introduced from the top down, with initial benefits coming from team interactions. Senior management at CP and L defined the corporate expectations and outlined the training requirements for implementing TQ. Management staffs at each organizational level became steering committees for TQ team activities within their departments. Teams of employees most knowledgeable about a given work area were empowered to solve problems or overcome obstacles related to that work area. Employees learned to become better team players and to appreciate the quality of decisions reached through group consensus. Now, formalized methods that started TQ are becoming part of the day-to-day work ethic

  17. Assessment of on-road emissions of four Euro V diesel and CNG waste collection trucks for supporting air-quality improvement initiatives in the city of Milan

    International Nuclear Information System (INIS)

    This paper summarizes the results of an extensive experimental study aiming to evaluate the performance and pollutant emissions of diesel and CNG waste collection trucks under realistic and controlled operating conditions in order to support a fleet renewal initiative in the city of Milan. Four vehicles (1 diesel and 3 CNG) were tested in two phases using a portable emission measurement system. The first phase included real world operation in the city of Milan while the second involved controlled conditions in a closed track. Emissions recorded from the diesel truck were on average 2.4 kg/km for CO2, 0.21 g/km for HC, 7.4 g/km for CO, 32.3 g/km for NOx and 46.4 mg/km for PM. For the CNG the values were 3.6 kg/km for CO2, 2.19 g/km for HC, 15.8 g/km for CO, 4.38 g/km for NOx and 11.4 mg/km for PM. CNG vehicles presented an important advantage with regards to NOx and PM emissions but lack the efficiency of their diesel counterparts when it comes to CO, HC and particularly greenhouse gas emissions. This tradeoff needs to be carefully analyzed prior to deciding if a fleet should be shifted towards either technology. In addition it was shown that existing emission factors, used in Europe for environmental assessment studies, reflect well the operation for CNG but were not so accurate when it came to the diesel engine truck particularly for CO2 and NOx. With regard to NOx, it was also shh regard to NOx, it was also shown that the limits imposed by current emission standards are not necessarily reflected in real world operation, under which the diesel vehicle presented almost 4 times higher emissions. Regarding CO2, appropriate use of PEMS data and vehicle information allows for accurate emission monitoring through computer simulation. - Highlights: ? Investigated diesel and CNG Euro V waste collection vehicles for municipal use ? NOx-GhG emission trade-off should be considered prior to fleet renewal initiatives. ? NOx and CO emissions exceeded the emission standard values over realistic conditions. ? Current emission factors reflect adequately CNG but need update for diesel trucks. ? Simulation successfully used for CO2 monitoring, opens path for regulatory initiatives

  18. Strategy to Support Improvement of Healthcare Quality.

    Ing. Andrea Zejdlova

    2013-01-01

    Full Text Available One of the latest market-based solutions to the rising costs and quality gaps in health care is pay for performance. Pay for performance is the use of financial incentives to promote the delivery of designated standards of care. It is an emerging movement in health insurance (initially in Britain and United States. Providers under this arrangement are rewarded for meeting pre-established targets for delivery of healthcare services. This is a fundamental change from fee for service payment.Also known as "P4P" or “value-based purchasing,” this payment model rewards physicians, hospitals, medical groups, and other healthcare providers for meeting certain performance measures for quality and efficiency. Disincentives, such as eliminating payments for negative consequences of care (medical errors or increased costs, have also been proposed. In the developed nations, the rapidly aging population and rising health care costs have recently brought P4P to the forefront of health policy discussions. Pilot studies underway in several large healthcare systems have shown modest improvements in specific outcomes and increased efficiency, but no cost savings due to added administrative requirements. Statements by professional medical societies generally support incentive programs to increase the quality of health care, but express concern with the validity of quality indicators, patient and physician autonomy and privacy, and increased administrative burdens. This article serves as an introduction to pay for performance. We discuss the goals and structure of pay for performance plans and their limitations and potential consequences in the health care area.

    2007-06-01

    With the rapid expansion of knowledge and technology and a health care system that performs far below acceptable levels for ensuring patient safety and needs, front-line health care professionals must understand the basics of quality improvement methodologies and terminology. The goals of this review are to provide clinicians with sufficient information to understand the fundamentals of quality improvement, provide a starting point for improvement projects, and stimulate further inquiry into the quality improvement methodologies currently being used in health care. Key quality improvement concepts and methodologies, including plan-do-study-act, six-sigma, and lean strategies, are discussed, and the differences between quality improvement and quality-of-care research are explored.

    Improving the quality of clinical care and translating evidence into clinical practice is commonly a focus of primary care research. This article is part of a series on primary care research and outlines an approach to performing a quality improvement cycle as part of a research assignment at a Masters level. The article aims to help researchers design their quality improvement cycle and write their research project proposal.

  1. Ways of castings quality improvement

    International Nuclear Information System (INIS)

    By the method of mathematical statistics at computer studied is the dependence of hot cracking in steam turbine castings made of 15KhM1FL steel on chemical composition and on the melting procedure (duration of oxidating and reducing periods, regime of carbon oxidation, preliminary deoxidation of metal, etc.). On the basis of results of statistical and experimental studies the melting procedure for the 15Kh1MFL steel has been modified and the optimum chemical composition, providing maximum crack resistance, has been recommended. It is found that metal quality can be sufficiently improved at the expense of its refining with synthetic slag in the ladle. Metal, treated with synthetic slag, has transition temperature lower in 20 deg C than that, melted according to the existing technology. Long-term plasticity of the 15Kh1M1FL steel treated with synthetic slag, is 20% higher than the usual one, at the same level of long-term strength at test temperature of 565 deg C that is important for service reliability of castings

    General practitioners often have difficulty in dealing with dissatisfied patients. One underlying reason could be the disturbed relationship between the doctor and the dissatisfied patient. A training course has been developed taking the relationship as a starting-point. Based on Watzlawick et al.'s theory on communication GPs have been trained to react to a dissatisfied patient on a relational level ('Are you dissatisfied with my treatment?') rather than on a contents level ('How long have you been suffering from this?'). This method seeks to improve the relationship and the satisfaction of both doctor and patient. Three types of initial reaction to dissatisfied patients were offered to four groups of GPs (19 trainees in general practice and 19 trainers in general practice). Pre- and post-measurement were executed by means of registering the initial reactions on videorecorded vignettes of re-enacted dissatisfied patients. Subsequently the reactions were categorized blind by two judges. The 12 possible categories can be subdivided into categories primarily aimed at the contents or primarily aimed at the relationship. The results show that, as compared to the pre-measurements, GPs more frequently use empathic reactions and reactions in which they bring their own actions up for discussion. The number of responses in which doctors ask a further clinical question or in which GPs expect a solution whether from themselves or from others, decrease. It is concluded that the course appears to change for the better the GPs' initial reaction to dissatisfied patients. PMID:8412882

    Paper-based surveys are an effective means of evaluating the quality of a clinical service. As part of ongoing quality improvement initiatives within our Genetics Program, new patients were invited to participate in a paper-based survey. Issues related to the quality of counseling based on educational/informational aspects (e.g. whether testing was explained fully, testing options, the meaning of normal/abnormal testing), competency, respect and nondirectiveness of counseling in addition to clinical environment/setting were evaluated. Data related to demographics, discipline seen within the program and whether the patient was seen by a physician or genetic counselor were also captured. Five hundred questionnaires were distributed. One hundred and forty-seven questionnaires were returned, with a response rate of 29.4 %. The majority of patients seen were prenatal (pregnant) patients and comprised a heterogeneous group including those seen for advanced maternal age and abnormal maternal serum screening. Overall, 98.6 % of respondents felt their appointment in genetics was a positive experience. Issues related to confidentiality, pros and cons of testing, meaning of an abnormal test result and time allotted for decision making were significantly different in some disciplines between genetic counselor and geneticist. However, when controlling for referral indication, these differences lost significance with the exception of issues relating to confidentiality and perceived time allotted to organize thoughts and questions. This survey provided valuable information to allow for improvement in the quality of the provision of service. PMID:24647747

    1995-01-01

    In may 1994 we were selected by the surgical Swiss association to make a study about quality in USA. During our travel we visited 3 types of institutions: Hospitals, National Institute of standard and Technology, Industry, Johnson & Johnson. We appreciate to compare 2 types of quality programs: Quality Assurance (QA) and Continuous Quality Improvement (CQI). In traditional healthcare circles, QA is the process established to meet external regulatory requirements and to assure that patient care is consistent with established standards. In a modern quality terms, QA outside of healthcare means designing a product or service, as well as controlling its production, so well that quality is inevitable. The ideas of W. Edward Deming is that there is never improvement just by inspection. He developed a theory based on 14 principles. A productive work is accomplished through processes. Understanding the variability of processes is a key to improve quality. Quality management sees each person in an organisation as part of one or more processes. The job of every worker is to receive the work of others, add value to that work, and supply it to the next person in the process. This is called the triple role the workers as customer, processor, and supplier. The main source of quality defects is problems in the process. The old assumption is that quality fails when people do the right thing wrong; the new assumption is that, more often, quality failures arise when people do the wrong think right. Exhortation, incentives and discipline of workers are unlikely to improve quality. If quality is failing when people do their jobs as designed, then exhorting them to do better is managerial nonsense. Modern quality theory is customer focused. Customers are identified internally and externally. The modern approach to quality is thoroughly grounded in scientific and statistical thinking. Like in medicine, the symptom is a defect in quality. The therapist of process must perform diagnostic test, formulate hypotheses of cause, test those hypotheses, apply remedies, and assess the effect of remedies. Total employee involvement is critical. A power comes from enabling all employees to become involved in quality improvement. A great advantage of CQI is the prevention orientation of the concept. The CQI permeated a collegial approach, people learn how to work together to improve. CQI is a time consuming procedure. During our travel we learned the definition of quality as the customer satisfaction. To build a CQI concept in employed time but all employed are involved in quality improvement. Applying CQI we could be able to refuse Quality control programs. PMID:8581805

    It is now well known that the history of quality improvement is neither uniquely American, nor uniquely Japanese, although the contributions from these two nations have received more attention perhaps than those originating elsewhere. This is the first in a series of articles intended to increase awareness of quality improvement practices and trends in various European nations, with particular emphasis on western Europe and Scandinavia. Herein the recent history of quality improvement in Denmark is explored and the quality improvement efforts in two Danish companies are chronicled. It is hoped that taken in its entirety, this series of articles will contribute to understanding both the rich fabric of European quality improvement that is independent of national boundaries and the colorful national fibers of which the fabric is made.

    2014-04-01

    Full Text Available Power quality determines the fitness of electrical power to consumer devices. Synchronization of the voltage frequency and phase allows electrical systems to function in their intended manner without significant loss of performance or life. The term is used to describe electric power that drives an electrical load and the load's ability to function properly. Without the proper power, an electrical device (or load may malfunction, fail prematurely or not operate at all. There are many ways in which electric power can be of poor quality and many more causes of such poor quality power. This paper proposes a new connection for a unified power quality conditioner (UPQC to improve the power quality of two feeders in a distribution system. This paper illustrates how UPQC can improve the power quality by mitigating all these PQ disturbances. The proposed configuration of the UPQC is developed and verified for various Power Quality disturbances by simulating the model using MATLAB/Simulation

  20. EXFOR: Improving the quality of international databases

    International Nuclear Information System (INIS)

    The NEA Data Bank is an international centre of reference for basic nuclear tools used for the analysis and prediction of phenomena in nuclear energy applications. The Data Bank collects, compiles, disseminates and contributes to improving computer codes and associated data. In the area of nuclear data, the Data Bank works in close co-operation with other data centres that contribute to the worldwide compilation of experimental nuclear reaction data in the EXFOR database. EXFOR contains basic nuclear data on low- to medium-energy experiments for incident neutron, photon and various charged particle induced reactions on a wide range of nuclei and compounds. Today, with more than 150 000 data sets from more than 20 000 experiments performed since 1935, EXFOR is by far the most important and complete experimental nuclear reaction database. It is widely used to further improve nuclear reaction models and evaluated nuclear data libraries. The Data Bank supervises the development of the Joint Evaluated Fission and Fusion (JEFF) file, which is one of the major evaluated nuclear data libraries used in the field of nuclear science and technology. As part of its mission, the Data Bank works to maintain the highest level of quality in its databases. One method that was proposed to check the mutual consistency of experimental data in EXFOR is to test for outlier measurements more than a few standard deviations from the mean value as, in principle, several measurements of the same reaction quantity should form a continuous distribution. More recently, another method was developed to cross-check evaluated and experimental data in databases in order to detect aberrant values. It was noted that there is no evidence, on the basis of numerical comparisons only, that outliers represent 'bad' data. The fact that such data deviate significantly from other data of the same reaction may, however, be helpful to nuclear data evaluators who focus on one or a few isotopes and may wish to discard such data after a thorough analysis. The Data Bank also organised a comprehensive review of cross-section data. An efficient review system and associated strategy were developed to systematically compare more than 10 000 cross-section data sets from EXFOR with the corresponding values in the main evaluated nuclear data libraries, including JEFF. The review initially covered all neutron-induced threshold and activation reactions such as (n,n'), (n,2n), (n,p) and (n,?). The resulting statistical information showed various interesting trends in the data, including a list of suspicious data sets for which the cross-section values deviate greatly from the major evaluated nuclear data libraries and/or other measurements. The original publications associated with these data have also been systematically checked. This work confirmed that most of the experimental data were compiled correctly in the EXFOR database, and it identified a few compilation mistakes that have since been corrected. A second part of the review devoted to the (n,?) cross-section is underway. This part of the review is challenging because of the large fluctuations of data in the resonance region that make the comparison more difficult. If successful, the review could be completed with other non-threshold cross-sections such as (n,f), (n,tot) and (n,n). All of these initiatives have been very useful to maintain the highest level of quality in the EXFOR database. In addition, future development versions of the JEFF library can be automatically benchmarked against other evaluated libraries and against a more reliable experimental database. Such work will contribute to improving the quality of evaluated nuclear data for the benefit of all users. (author)

(FDH) describing several DOE-RL identified failed opportunities for FDH to improve the Quality Assurance (QA) Program and its implementation. In addition, DOE-RL identified specific Quality Program performance deficiencies. FDH was requested to establish a periodic reporting mechanism for the corrective action program. In a July 17, 1998 response to DOE-RL, FDH agreed with the DOE concerns and committed to perform a comprehensive review of the Project Hanford Management Contract (PHMC) QA Program during July and August, 1998. As a result, the Project Hanford Management Contract Quality Improvement Plan (QIP) (FDH-3508) was issued on October 21, 1998. The plan identified corrective actions based upon the results of an in-depth Quality Program Assessment. Immediately following the scheduled October 22, 1998, DOE Office of Enforcement and Investigation (EH-10) Enforcement Conference, FDH initiated efforts to effectively implement the QIP corrective actions. A Quality Improvement Project (QI Project) leadership team was assembled to prepare a Project Management Plan for this project. The management plan was specifically designed to engage a core team and the support of representatives from FDH and the major subcontractors (MSCs) to implement the QIP initiatives; identify, correct, and provide feedback as to the root cause for deficiency; and close out the corrective actions. The QI Project will manage and communicate progress of the process.

    Modern CT is a powerful yet increasingly complex technology that continues to rapidly evolve; optimal clinical implementation as well as appropriate quality management and improvement in CT are challenging but attainable. This article outlines the organizational structure on which a CT quality management and improvement program can be built, followed by a discussion of common as well as pediatric-specific challenges. Organizational elements of a CT quality management and improvement program include the formulation of clear objectives; definition of the roles and responsibilities of key personnel; implementation of a technologist training, coaching and feedback program; and use of an efficient and accurate monitoring system. Key personnel and roles include a radiologist as the CT director, a qualified CT medical physicist, as well as technologists with specific responsibilities and adequate time dedicated to operation management, CT protocol management and CT technologist education. Common challenges in managing a clinical CT operation are related to the complexity of newly introduced technology, of training and communication and of performance monitoring. Challenges specific to pediatric patients include the importance of including patient size in protocol and dose considerations, a lower tolerance for error in these patients, and a smaller sample size from which to learn and improve.

Organizational elements of a CT quality management and improvement program include the formulation of clear objectives; definition of the roles and responsibilities of key personnel; implementation of a technologist training, coaching and feedback program; and use of an efficient and accurate monitoring system. Key personnel and roles include a radiologist as the CT director, a qualified CT medical physicist, as well as technologists with specific responsibilities and adequate time dedicated to operation management, CT protocol management and CT technologist education. Common challenges in managing a clinical CT operation are related to the complexity of newly introduced technology, of training and communication and of performance monitoring. Challenges specific to pediatric patients include the importance of including patient size in protocol and dose considerations, a lower tolerance for error in these patients, and a smaller sample size from which to learn and improve.

    Full Text Available Abstract Background The Department of Veterans Affairs (VA has led the industry in measuring facility performance as a critical element in improving quality of care, investing substantial resources to develop and maintain valid and cost-effective measures. The External Peer Review Program (EPRP of the VA is the official data source for monitoring facility performance, used to prioritize the quality areas needing most attention. Facility performance measurement has significantly improved preventive and chronic care, as well as overall quality; however, much variability still exists in levels of performance across measures and facilities. Audit and feedback (A&F, an important component of effective performance measurement, can help reduce this variability and improve overall performance. Previous research suggests that VA Medical Centers (VAMCs with high EPRP performance scores tend to use EPRP data as a feedback source. However, the manner in which EPRP data are used as a feedback source by individual providers as well as service line, facility, and network leadership is not well understood. An in-depth understanding of mental models, strategies, and specific feedback process characteristics adopted by high-performing facilities is thus urgently needed. This research compares how leaders of high, low, and moderately performing VAMCs use clinical performance data from the EPRP as a feedback tool to maintain and improve quality of care. Methods We will conduct a qualitative, grounded theory analysis of up to 64 interviews using a novel method of sampling primary care, facility, and Veterans Integrated Service Network (VISN leadership at high-, moderate-, and low-performing facilities. We will analyze interviews for evidence of cross-facility differences in perceptions of performance data usefulness and strategies for disseminating performance data evaluating performance, with particular attention to timeliness, individualization, and punitiveness of feedback delivery. Discussion Most research examining feedback to improve provider and facility performance lacks a detailed understanding of the elements of effective feedback. This research will highlight the elements most commonly used at high-performing facilities and identify additional features of their successful feedback strategies not previously identified. Armed with this information, practices can implement more effective A&F interventions to improve quality of care.

    2011-01-01

    Geomagnetic observatory practice and instrumentation has evolved significantly over the past 150 years. Evolution continues to be driven by advances in technology and by the need of the data user community for higher-resolution, lower noise data in near-real time. Additionally, collaboration between observatories and the establishment of observatory networks has harmonized standards and practices across the world; improving the quality of the data product available to the user. Nonetheless, operating a highquality geomagnetic observatory is non-trivial. This article gives a record of the current state of observatory instrumentation and methods, citing some of the general problems in the complex operation of geomagnetic observatories. It further gives an overview of recent improvements of observatory data quality based on presentation during 11th IAGA Assembly at Sopron and INTERMAGNET issues.

    Approximately 30% of cases of couple infertility are due to a male factor. Several conditions can interfere with spermatogenesis and reduce sperm quality and production. Treatable conditions, such as hypogonadism, varicocele, infections and obstructions, should be diagnosed and corrected, but many aspects of male factor infertility remain unclear. Various agents have been used in the attempt to increase the fertility potential of subjects with idiopathic oligoteratoasthenozoospermia. The rationale of medical treatment to improve sperm quality in these subjects has been questioned by the introduction of assisted reproductive technologies. However, there is now growing awareness of the importance of good quality spermatozoa for embryonic development and higher birth rates. Confounding factors in assessing the efficacy of male infertility treatments have erroneously inflated the superiority of assisted reproductive technologies over conventional approaches. A systematic review is given of relevant randomized controlled trials and effects on semen parameters. The analysis reveals that although results are heterogeneous, gonadotrophins, anti-oestrogens, carnitine and trace elements may be beneficial in improving sperm quality, although their effect on pregnancy rate remains controversial. The most common drug regimens are compared and an estimate of the results expected from these treatments provided. PMID:16792845

  4. Multichannel DBS halftoning for improved texture quality

    Slavuj, Radovan; Pedersen, Marius

    2015-01-01

    The paper aims to develop a method for multichannel halftoning based on the Direct Binary Search (DBS) algorithm. We integrate specifics and benefits of multichannel printing into the halftoning method in order to further improve texture quality of DBS and to create halftoning that would suit for multichannel printing. Originally, multichannel printing is developed for an extended color gamut, at the same time additional channels can help to improve individual and combined texture of color halftoning. It does so in a similar manner to the introduction of the light colors (diluted inks) in printing. Namely, if one observes Red, Green and Blue inks as the light version of the M+Y, C+Y, C+M combinations, the visibility of the unwanted halftoning textures can be reduced. Analogy can be extent to any number of ink combinations, or Neugebauer Primaries (NPs) as the alternative building blocks. The extended variability of printing spatially distributed NPs could provide many practical solution and improvements in color accuracy, image quality, and could enable spectral printing. This could be done by selection of NPs per dot area location based on the constraint of the desired reproduction. Replacement with brighter NP at the location could induce a color difference where a tradeoff between image quality and color accuracy is created. With multichannel enabled DBS haftoning, we are able to reduce visibility of the textures, to provide better rendering of transitions, especially in mid and dark tones.

    Many have recognized the need for high quality data on assets and the problems in obtaining them, particularly when there is a need for human observation and manual recording. Yet very few have looked at the role of the data collectors themselves in the data quality process. This paper argues that there are benefits to more fully understanding the psychological factors that lay behind data collection and we use goal hierarchy theory to understand these factors. Given the myriad of potential reasons for poor-quality data it has previously proven difficult to identify and successfully deploy employee-driven interventions; however, the goal hierarchy approach looks at all of the goals that an individual has in their life and the connections between them. For instance, does collecting data relate to whether or not they get a promotion? Stay safe? Get a new job? and so on. By eliciting these goals and their connections we can identify commonalities across different groups, sites or organizations that can influence the quality of data collection. Thus, rather than assuming what the data collectors want, a goal hierarchy approach determines that empirically. Practically, this supports the development of customized interventions that will be much more effective and sustainable than previous efforts. - Highlights: > We need to consider psychological aspects of data collectors to improve data quality. > We show how goal hierarchy theory furthers understanding. > Looks at the multiple goals of each individual to determine their behavior.

  7. Improving the quality of nursing documentation: An action research project

    Scientific Electronic Library Online (English)

    Elisha M., Okaisu; Florence, Kalikwani; Grace, Wanyana; Minette, Coetzee.

    Full Text Available BACKGROUND: Documentation is an important function of professional nursing practise. In spite of numerous improvement efforts globally, inadequate documentation continues to be reported as nurse authors investigate barriers and challenges. OBJECTIVES: The project aimed to improve nurses' documentati [...] on of their patient assessments at the CURE Children's Hospital of Uganda in order to enhance the quality of nursing practise. METHOD: An action research methodology, using repeated cycles of planning, intervention, reflection and modification, was used to establish best practise approaches in this context for improving nurses' efficacy in documenting assessments in the patient record. The researchers gathered data from chart audits, literature reviews and key informant interviews. Through analysis and critical reflection, these data informed three cycles of systems and practise modifications to improve the quality of documentation. RESULTS: The initial cycle revealed that staff training alone was insufficient to achieve the project goal. To achieve improved documentation, broader changes were necessary, including building a critical mass of competent staff, redesigned orientation and continuing education, documentation form redesign, changes in nurse skill mix, and continuous leadership support. CONCLUSION: Improving nursing documentation involved complex challenges in this setting and demanded multiple approaches. Evidence-based practise was the foundation of changes in systems required to produce visible improvement in practise. The involved role of leadership in these efforts was very important.

  10. IMPROVING (SOFTWARE) PATENT QUALITY THROUGH THE ADMINISTRATIVE PROCESS.

    Science.gov (United States)

    Rai, Arti K

    2013-11-24

    The available evidence indicates that patent quality, particularly in the area of software, needs improvement. This Article argues that even an agency as institutionally constrained as the U.S. Patent and Trademark Office ("PTO") could implement a portfolio of pragmatic, cost-effective quality improvement strategies. The argument in favor of these strategies draws upon not only legal theory and doctrine but also new data from a PTO software examination unit with relatively strict practices. Strategies that resolve around Section 112 of the patent statute could usefully be deployed at the initial examination stage. Other strategies could be deployed within the new post-issuance procedures available to the agency under the America Invents Act. Notably, although the strategies the Article discusses have the virtue of being neutral as to technology, they are likely to have a very significant practical impact in the area of software.

    International Nuclear Information System (INIS)

    On July 13, 1998, the U.S. Department of Energy, Richland Operations Office (DOE-RL) Manager transmitted a letter to Fluor Daniel Hanford, Inc. (FDH) describing several DOE-RL identified failed opportunities for FDH to improve the Quality Assurance (QA) Program and its implementation. In addition, DOE-RL identified specific Quality Program performance deficiencies. FDH was requested to establish a periodic reporting mechanism for the corrective action program. In a July 17, 1998 response to DOE-RL, FDH agreed with the DOE concerns and committed to perform a comprehensive review of the Project Hanford Management Contract (PHMC) QA Program during July and August, 1998. As a result, the Project Hanford Management Contract Quality Improvement Plan (QIP) (FDH-3508) was issued on October 21, 1998. The plan identified corrective actions based upon the results of an in-depth Quality Program Assessment. Immediately following the scheduled October 22, 1998, DOE Office of Enforcement and Investigation (EH-10) Enforcement Conference, FDH initiated efforts to effectively implement the QIP corrective actions. A Quality Improvement Project (QI Project) leadership team was assembled to prepare a Project Management Plan for this project. The management plan was specifically designed to engage a core team and the support of representatives from FDH and the major subcontractors (MSCs) to implement the QIP initiatives; identify, correct, and provide feedback as to the root cause for defiide feedback as to the root cause for deficiency; and close out the corrective actions. The QI Project will manage and communicate progress of the process

    Cell Membrane Chromatography (CMC) is a biological affinity chromatographic method using a silica stationary phase covered with specific cell membrane. However, its short life span and poor quality control was highlighted in a lot of research articles. In this study, special attention has been paid to the disruption, cell load and packing procedure in order to improve the quality of the CMC columns. Hereto, two newly established CMC models, HSC-T6/CMC and SMMC-7721/CMC have been developed and used in this research project. The optimization of the abovementioned parameters resulted in a better reproducibility of the retention time of the compound GFT (RSDcycles (400W and 20s interval per cycle) by an ultrasonic processor reducing the total time of cell disruption to 1.5min and the packing flow rate was optimized by applying a linear gradient program. Additionally, 4% paraformaldehyde (PFA) was employed to improve the column quality and prolong the column life span. The results showed that the retention time was longer with PFA treated columns than the ones obtained with the control groups. PMID:25115453

    Full Text Available Abstract Background Despite several years of implementation, prevention of mother-to-child transmission (PMTCT programmes in many resource poor settings are failing to reach the majority of HIV positive women. We report on a data driven participatory quality improvement intervention implemented in a high HIV prevalence district in South Africa. Methods A participatory quality improvement intervention was implemented consisting of an initial assessment undertaken by a team of district supervisors, workshops to assess results, identify weaknesses and set improvement targets and continuous monitoring to support changes. Results The assessment highlighted weaknesses in training and supervision. Routine data revealed poor coverage of all programme indicators except HIV testing. Monthly support to all facilities took place including an orientation to the PMTCT protocol, review of local data and identification of bottlenecks to optimal coverage using a continuous quality improvement approach. One year following the intervention large improvements in programme indicators were observed. Coverage of CD4 testing increased from 40 to 97%, uptake of maternal nevirapine from 57 to 96%, uptake of infant nevirapine from 15 to 68% and six week PCR testing from 24 to 68%. Conclusion It is estimated that these improvements in coverage could avert 580 new infant infections per year in this district. This relatively simple participatory assessment and intervention process has enabled programme managers to use a data driven approach to improve the coverage of this important programme.

    2015-01-01

    Construction of binary black hole initial data is a prerequisite for numerical evolutions of binary black holes. This paper reports improvements to the binary black hole initial data solver in the Spectral Einstein Code, to allow robust construction of initial data for mass-ratio above 10:1, and for dimensionless black hole spins above 0.9, while improving efficiency for lower mass-ratios and spins. We implement a more flexible domain decomposition, adaptive mesh refinement and an updated method for choosing free parameters. We also introduce a new method to control and eliminate residual linear momentum in initial data for precessing systems, and demonstrate that it eliminates gravitational mode mixing during the evolution. Finally, the new code is applied to construct initial data for hyperbolic scattering and for binaries with very small separation.

  15. Increased office productivity through improved indoor air quality

    DEFF Research Database (Denmark)

    Fanger, Povl Ole

    2002-01-01

    Control of indoor pollution sources and ventilation are both means of improving indoor air quality. Three independent experiments have recently documented that removing a pollution source or increasing the ventilation rate will improve perceived air quality, reduce the intensity of several Sick Building Syndrome (SBS) symptoms and improve the productivity of office workers. In these experiments, the performance of simulated office work (text typing, addition and proof-reading, all typical office tasks requiring concentration) improved monotonically as the proportion of persons dissatisfied with the air quality was reduced by either measure. The quantitative relationsh8ip was 1.1% change in performance per 10% dissatisfied, in the range 25-70% dissatisifed, or 0.5% change in performance per 1 decipol (dp), in the range 2-13 dp. Significant improvements in performance occurred only when the intensity of general SBS symptoms such as headache and difficulty in thinking clearly were significantly reduced, which implies that this was the mechanism of causation. The performance of simulated office work increased monotonically with decreasing pollution load by a 1.6% increase in performance for each twofold decrease of pollution load in the range 0.3-2 olf/m2floor, and with increasing outdoor air supply rate by a 1.8% increase in performance for each twofold increase in the outdoor air supply rate in the range 0.8-5.3 L/s per olf. As these results clearly justify increased initial and operating costs, future developments in HVCAC technology may include "personalized air ", new ways of improving the quality of supply air (e.g., by filtration), more extensive use of heat recovery from exhaust air and systematic selection of low-polluting building and furnishing materials.

  16. Improving wind power quality with energy storage

    Rasmussen, Claus Nygaard

    2009-01-01

    The results of simulation of the influence of energy storage on wind power quality are presented. Simulations are done using a mathematical model of energy storage. Results show the relation between storage power and energy, and the obtained increase in minimum available power from the combination of wind and storage. The introduction of storage enables smoothening of wind power on a timescale proportional to the storage energy. Storage does not provide availability of wind power at all times, but allows for a certain fraction of average power in a given timeframe to be available with high probability. The amount of storage capacity necessary for significant wind power quality improvement in a given period is found to be 20 to 40% of the energy produced in that period. The necessary power is found to be 80 to 100% of the average power of the period.

  20. Improving energy audit process and report outcomes through planning initiatives

    Science.gov (United States)

    Sprau Coulter, Tabitha L.

    Energy audits and energy models are an important aspect of the retrofit design process, as they provide project teams with an opportunity to evaluate a facilities current building systems' and energy performance. The information collected during an energy audit is typically used to develop an energy model and an energy audit report that are both used to assist in making decisions about the design and implementation of energy conservation measures in a facility. The current lack of energy auditing standards results in a high degree of variability in energy audit outcomes depending on the individual performing the audit. The research presented is based on the conviction that performing an energy audit and producing a value adding energy model for retrofit buildings can benefit from a revised approach. The research was divided into four phases, with the initial three phases consisting of: 1.) process mapping activity - aimed at reducing variability in the energy auditing and energy modeling process. 2.) survey analysis -- To examine the misalignment between how industry members use the top energy modeling tools compared to their intended use as defined by software representatives. 3.) sensitivity analysis -- analysis of the affect key energy modeling inputs are having on energy modeling analysis results. The initial three phases helped define the need for an improved energy audit approach that better aligns data collection with facility owners' needs and priorities. The initial three phases also assisted in the development of a multi-criteria decision support tool that incorporates a House of Quality approach to guide a pre-audit planning activity. For the fourth and final research phase explored the impacts and evaluation methods of a pre-audit planning activity using two comparative energy audits as case studies. In each case, an energy audit professionals was asked to complete an audit using their traditional methods along with an audit which involved them first participating in a pre-audit planning activity that aligned the owner's priorities with the data collection. A comparative analysis was then used to evaluate the effects of the pre-audit planning activity in developing a more strategic method for collecting data and representing findings in an energy audit report to a facility owner. The case studies demonstrated that pre-audit planning has the potential to improve the efficiency of an energy audit process through reductions in transition time waste. The cases also demonstrated the value of audit report designs that are perceived by owners to be project specific vs. generic. The research demonstrated the ability to influence and alter an auditors' behavior through participating in a pre-audit planning activity. It also shows the potential benefits of using the House of Quality as a method of aligning data collection with owner's goals and priorities to develop reports that have increased value.

  4. Enhanced fuel performance by improving pellet quality and fabrication technology

    International Nuclear Information System (INIS)

    As part of Westinghouse flawless fuel initiatives, Westinghouse has initiated companywide efforts to enhance overall quality of UO2 pellets by enhancing pellet surface quality, pressing processes, examining pellet handling during various stages of pellet fabrication process and enhancing inspection process with primary focus of reducing pellets with missing surfaces. Benchmarking/best practices were examined among all Westinghouse and some of the Westinghouse licensee sites to minimize pellet chipping, enhance overall pellet quality and improve inspection processes. Numbers of 3-Dimensional (3-D) finite element models were developed to analyze the impact of cladding and pellet defects on the cladding temperature, stress and strain. The Finite Element Analysis (FEA) results demonstrated that: 1. Large Missing Pellet Surface (MPS) influences the fuel rod performance characteristics such as temperature, stress and strain distributions and 2. MPS dimensions should be controlled to improve the fuel rod performance characteristic impact. Based on the FEA conclusion, review of the in-reactor fuel performance of pellets with chamfers, characterization of pellets with side chips and correlating all of the above, a new set of criteria for side chips was identified and implemented. By analyzing each process step in pellet manufacturing and performing studies to determine forces needed to induce chipping in pellets, a knowledge based handling system can be established. based handling system can be established. Critical steps were identified and analyzed for handling of pellets between the processes steps of pellet pressing and storage. Extensive process evaluations and tests have been completed in manufacturing to show that manual inspection is effective. As deemed necessary, manual inspection process was modified to further enhance current manual inspection process. Westinghouse has also initiated a development effort to replace manual inspection with an automatic inspection system for pellets. Different sites use different conversion and pelleting processes and therefore site specific improvements are being made where it would have most impact. (author)

    Human biospecimens are subjected to collection, processing, and storage that can significantly alter their molecular composition and consistency. These biospecimen preanalytical factors, in turn, influence experimental outcomes and the ability to reproduce scientific results. Currently, the extent and type of information specific to the biospecimen preanalytical conditions reported in scientific publications and regulatory submissions varies widely. To improve the quality of research that uses human tissues, it is crucial that information on the handling of biospecimens be reported in a thorough, accurate, and standardized manner. The Biospecimen Reporting for Improved Study Quality (BRISQ) recommendations outlined herein are intended to apply to any study in which human biospecimens are used. The purpose of reporting these details is to supply others, from researchers to regulators, with more consistent and standardized information to better evaluate, interpret, compare, and reproduce the experimental results. The BRISQ guidelines are proposed as an important and timely resource tool to strengthen communication and publications on biospecimen-related research and to help reassure patient contributors and the advocacy community that their contributions are valued and respected.

  8. Improving smoked herring quality by gamma irradiation

    International Nuclear Information System (INIS)

    Smoked herring which is a highly purchasable product in Egypt, was exposed to different gamma irradiation doses (1.5,3.0 and 5.0 kGy) and stored at environmental temperature (12± 2 deg C) until spoilage of the control. Microbiological, chemical and sensory analyses were performed throughout storage to monitor the quality attributes. It is worthy to mention that irradiation reduced the population of bacteria and the effect was more pronounced at the highest dose used (5.0 kGy). At the same time 1.5 kGy completely eliminated staphylococcus aureus (coagulase + ve) and coliforms. By chemical analysis, there was significant decrease in average moisture content by different gamma irradiation doses and storage. Although the average thiobarbituric acid reactive substances (TBARS) increased slightly by ?-irradiation, this increase was highly significant by storage . At the same time there was a significant (p< 0.05)decrease in the average trimethylamine (TMA) value of all irradiated samples compared with unirradiated control, this value increased significantly by storage. interestingly, the average histamine value decreased significantly in all irradiated samples. The sensory analysis revealed a highly significant difference in the average acceptability scores between different irradiation doses used and also by storage. Therefore it could be concluded that the quality of smoked herring during storage at environmental temperature (12 ± 2 deg C) could be improved by using 5. 2 deg C) could be improved by using 5.0 kGy ? -irradiation

    2006-01-01

    Enterprise Resource Planning Systems (ERP) has been implemented in many companies during the last decade and has gained an increasing significance. For many companies it means that the focus is no longer on how to implement the ERP system, but rather on how to maintain and improve the system to gain business benefits from the systems. However the ERP literature on how to do this is limited. The purpose of this article is to explore how Project Portfolio Management (PPM) from the Research and Development (R&D) literature can be applied to an ERP second wave context, when companies are to prioritize and select maintenance and continuous improvement initiatives. This is done by reviewing the existing literature in the fields of PPM from R&D literature and then by reviewing the existing literature about maintenance and improvement initiatives in the ERP literature, after which the two are compared and discussed using three case-studies. The paper contributes with a discussion on how PPM from R&D can be applied tomaintenance and continuous improvement initiatives in the second wave of ERP. The paper ends with arguing that emphasis needs to be given to this field, since a conscious and systematic prioritization of maintenance and improvement initiatives is believed to be able to increase business performance.

    2014-01-01

    Lung cancer is the commonest cause of cancer-related death worldwide and poses a significant respiratory disease burden. Little is known about the provision of lung cancer care across Europe. The overall aim of the Task Force was to investigate current practice in lung cancer care across Europe. The Task Force undertook four projects: 1) a narrative literature search on quality management of lung cancer; 2) a survey of national and local infrastructure for lung cancer care in Europe; 3) a benchmarking project on the quality of (inter)national lung cancer guidelines in Europe; and 4) a feasibility study of prospective data collection in a pan-European setting. There is little peer-reviewed literature on quality management in lung cancer care. The survey revealed important differences in the infrastructure of lung cancer care in Europe. The European guidelines that were assessed displayed wide variation in content and scope, as well as methodological quality but at the same time there was relevant duplication. The feasibility study demonstrated that it is, in principle, feasible to collect prospective demographic and clinical data on patients with lung cancer. Legal obligations vary among countries. The European Initiative for Quality Management in Lung Cancer Care has provided the first comprehensive snapshot of lung cancer care in Europe.

    Curry, A C; Keogh, W; Hogg, G M

    1997-05-01

    This paper is a review of a quality of service initiative which was carried out as a PICKUP Quality Project within the Scottish Health Service. This Quality Initiative took place between 1989 and 1990: before the emergence of The Patient's Charter. The aim of the review was to provide answers to a number of important questions which examined the perceptions of staff who took part in the Quality of Service initiative, identified parts of the process which were in need of substantial revision, and reported on the reactions of participants to the overall process. The methodology employed involved questionnaires and interview techniques. A number of problems were identified and, after examination, these were taken to indicate learning pointers for the future. It was evident that good quality of service training can be delivered, but only if it is clearly and appropriately tailored to the audience. It is also of fundamental importance to be familiar with the environment in which the organization is operating. In this instance, as is often the case for health care, there were considerable financial limitations in force at the time. These limitations heightened the general business sensitivity and showed that carrying through quality of service improvements involved the demonstration of commitment and the provision of resources.

    1994-03-01

    Members of the Task HI (Strategic Evaluation) team were responsible for the development of a methodology to evaluate policies designed to alleviate air pollution in Mexico City. This methodology utilizes information from various reports that examined ways to reduce pollutant emissions, results from models that calculate the improvement in air quality due to a reduction in pollutant emissions, and the opinions of experts as to the requirements and trade-offs that are involved in developing a program to address the air pollution problem in Mexico City. The methodology combines these data to produce comparisons between different approaches to improving Mexico City`s air quality. These comparisons take into account not only objective factors such as the air quality improvement or cost of the different approaches, but also subjective factors such as public acceptance or political attractiveness of the different approaches. The end result of the process is a ranking of the different approaches and, more importantly, the process provides insights into the implications of implementing a particular approach or policy.

  14. Improving quality of cancer care through surgical audit

    van Gijn, W; van de Velde, C J H

    2010-01-01

    Quality of healthcare is a hot topic and this is especially true for cancer care. New surgical techniques and effective neoadjuvant treatment regimens have significantly improved colorectal cancer outcome. Nevertheless, there seem to be substantial differences in quality of care between European countries, hospitals and doctors. To reduce hospital variation, most initiatives aim on selective referral, encouraging patients to seek care in high-volume hospitals, where cancer care is concentrated to site-specialist multidisciplinary teams. As an alternative to volume-based referral, hospitals and surgeons can also improve their results by learning from their own outcome statistics and those from colleagues treating a similar patient group. European national audit registries in surgical oncology have led to improvements with a greater impact on survival than any of the adjuvant therapies currently under study. Moreover, they offer the possibility to perform research on patient groups that are usually excluded from clinical trials. Nevertheless, between European countries remain differences in outcome and treatment schedules that cannot be easily explained. The European CanCer Organisation (ECCO) has recognised these importances and created the 'European Registration of Cancer Care' (EURECCA) framework to develop a European colorectal audit structure. EURECCA will advance future treatment improvements and spread these to all European cancer patients. It provides opportunities to treat elderly and comorbid patients evidence based while it offers an unique insight in social-economical healthcare matters such as the consequences of commercialisation, treatment availability and screening initiatives. As such, ECCO has established the basis for a strong, multidisciplinary audit structure with the commitment to improve cancer care for every European cancer patient.

    1995-03-01

    In the hospital environment, vendors supply a wide range of items, from surgical sutures to the latest in high-cost technological equipment. Also, many clinical and support services, such as respiratory therapy, transcription, and computer databanks are now outsourced to commercial vendors. Interaction with such vendors is often less than satisfactory, with prolonged timelines and disruption of an important process that is being computerized. Although hospitals deal with very few vendors in long-term relationships, such as those seen in manufacturing, this should not preclude the formation of a supplier-customer relationship that goes beyond management's interaction with the sales representative in response to a request for proposal. This is especially true when a process improvement team has studied an internal process and defined a key quality characteristic. PMID:10140905

    Full Text Available This study explores the role of Non-formal Primary Education (NFPE in improving the quality of the life of underprivileged children in Bangladesh considering their economic, health, environmental issues and life skills. It uses a mixed method approach of research where three NGOs which run NFPE programs were selected purposefully. Data were derived from six NGO officers, nine teachers, ninety students and eighteen guardians by using two sets of questionnaires for NGO officers and teachers, an interview schedule for guardians and 9 focus group discussions with the students. The findings show that there is no income generating program initiated by the organizations for the learners along with education. So, the scope of their income has reduced. But their daily life behavior and skills have improved. Besides, their awareness on health and environmental issues have increased. The findings lead to some recommendations which will give insights to policy makers and professionals engaged in this field.

    In captivity, male Asian elephants often yield poor quality semen after transrectal manually assisted semen collection; however, the reasons for the disappointing semen quality are not clear. Here we test the hypothesis that accumulation of senescent spermatozoa is a contributory factor, and that semen quality can therefore be improved by more frequent ejaculation. To this end we investigated the effect of collecting semen five times on alternate days, after a long period of sexual rest, on semen quality in Asian elephants known to deliver poor semen during infrequent single collections. All eight bulls initially displayed a high incidence of detached sperm heads and low percentages of motile (close to 0%) spermatozoa. After semen collection on alternate days, the percentages of detached sperm heads, and head and mid-piece abnormalities, were reduced significantly (p<0.05). In particular, one bull showed markedly improved sperm motility (increased from 0% to 60%) and membrane integrity (increased from 5% to 75%). In addition, advancing age significantly (p<0.01) correlated with lower percentages of sperm with intact membranes and a higher frequency of detached sperm heads. In contrast to sperm accumulation problems in other species, a small ampullary diameter correlated significantly (p<0.05) with reduced semen quality. PMID:24832106

    2014-11-01

    Full Text Available Background: In 2010, a National Laboratory Strategic Plan was set forth in Ethiopia to strengthen laboratory quality systems and set the stage for laboratory accreditation. As a result, the Strengthening Laboratory Management Toward Accreditation (SLMTA programme was initiated in 45 Ethiopian laboratories. Objectives: This article discusses the implementation of the programme, the findings from the evaluation process and key challenges. Methods: The 45 laboratories were divided into two consecutive cohorts and staff from each laboratory participated in SLMTA training and improvement projects. The average amount of supportive supervision conducted in the laboratories was 68 hours for cohort I and two hours for cohort II. Baseline and exit audits were conducted in 44 of the laboratories and percent compliance was determined using a checklist with scores divided into zero- to five-star rating levels. Results: Improvements, ranging from < 1 to 51 percentage points, were noted in 42 laboratories, whilst decreases were recorded in two. The average scores at the baseline and exit audits were 40% and 58% for cohort I (p < 0.01; and 42% and 53% for cohort II (p < 0.01, respectively. The p-value for difference between cohorts was 0.07. At the exit audit, 61% of the first and 48% of the second cohort laboratories achieved an increase in star rating. Poor awareness, lack of harmonisation with other facility activities and the absence of a quality manual were challenges identified. Conclusion: Improvements resulting from SLMTA implementation are encouraging. Continuous advocacy at all levels of the health system is needed to ensure involvement of stakeholders and integration with other improvement initiatives and routine activities.

    Nursing leadership opportunities to improve quality and align resources in health care exist. An estimated 18% of United States gross domestic product is spent on health care delivery systems that produce poor outcomes. The purpose of this article was to describe how quality improvement and implementation science initiatives enhance outcomes using nursing leadership strategies that play an integral role in aligning key colleagues to drive the collaborative process. A critical appraisal of the literature was conducted, which supports the importance of evidenced-based practice improvement, collaborative change process, and professional role of nursing leadership. Limited evidence exists related to practice strategies for nursing leaders to implement sustainable change at the unit level for successful alignment of resources. Strategies based on Rogers' Diffusion of Innovation Theory are recommended to address the gap in the literature. The strategies aim to increase meaningful knowledge or the "why," create a tipping point, and implement sustainable change starting with the end in mind. Nurse leaders are a central component for driving alignment and implementing change at the unit level. Uses of the described evidenced-based strategies have implications for nursing practice, education, and scholarship. PMID:26049600

    2013-08-28

    In organized healthcare quality improvement collaboratives (QICs), teams of practitioners from different hospitals exchange information on clinical practices with the aim of improving health outcomes at their own institutions. However, what works in one hospital may not work in others with different local contexts because of nonlinear interactions among various demographics, treatments, and practices. In previous studies of collaborations where the goal is a collective problem solving, teams of diverse individuals have been shown to outperform teams of similar individuals. However, when the purpose of collaboration is knowledge diffusion in complex environments, it is not clear whether team diversity will help or hinder effective learning. In this paper, we first use an agent-based model of QICs to show that teams comprising similar individuals outperform those with more diverse individuals under nearly all conditions, and that this advantage increases with the complexity of the landscape and level of noise in assessing performance. Examination of data from a network of real hospitals provides encouraging evidence of a high degree of similarity in clinical practices, especially within teams of hospitals engaging in QIC teams. However, our model also suggests that groups of similar hospitals could benefit from larger teams and more open sharing of details on clinical outcomes than is currently the norm. To facilitate this, we propose a secure virtual collaboration system that would allow hospitals to efficiently identify potentially better practices in use at other institutions similar to theirs without any institutions having to sacrifice the privacy of their own data. Our results may also have implications for other types of data-driven diffusive learning such as in personalized medicine and evolutionary search in noisy, complex combinatorial optimization problems.

  4. Quality procedure management for improved nuclear safety

    International Nuclear Information System (INIS)

    Emergency Operating Procedures and Accident Management Procedures are the next step in the computerization of NPP control rooms. Different improvements are presently conceivable for this operator aid tool, and research activities are in development. Undergoing activities regard especially formal aspects of knowledge representation, Human-Machine interface and procedure life cycle management. These aspects have been investigated deeply by Ansaldo, and partially incorporated in the DIAM prototype. Nuclear Power Plant Procedures can be seen from essentially two viewpoints: the process and the information management. From the first point of view, it is important to supply the knowledge apt to solve problems connected with the control of the process, from the second one the focus of attention is on the knowledge representation, its structure, elicitation and maintenance, and formal quality assurance. These two aspects of procedure representation can be considered and solved separately. In particular, methodological, formal and management issues require long and tedious activities, that in most cases constitute a great barrier for procedures development and upgrade. To solve these problems, Ansaldo is developing DIAM, a wide integrated tool for procedure management to support in procedure writing, updating, usage, and documentation. One of the most challenging features of DIAM is AUTO-LAY, a CASE sub-tool that, in a complete automatical way, structures parts or complete floical way, structures parts or complete flow diagram. This is the feature that is partial present in some other CASE products, that, anyway, do not allow complex graph handling and isomorphism between video and paper representation. AUTO-LAY has the unique prerogative to draw graphs of any complexity to section them in pages, and to automatically compose a document. This has been recognized in the literature as the most important a second-generation CASE improvement. (Author) 9 Figs., 5 Refs

    Full Text Available Abstract In 2004 a UK charity, The Health Foundation, established the 'Engaging with Quality Initiative' to explore and evaluate the benefits of engaging clinicians in quality improvement in healthcare. Eight projects run by professional bodies or specialist societies were commissioned in various areas of acute care. A developmental approach to the initiative was adopted, accompanied by a two level evaluation: eight project self-evaluations and a related external evaluation. This paper describes how the protocol for the external evaluation was developed. The challenges faced included large variation between and within the projects (in approach, scope and context, and in understanding of quality improvement, the need to support the project teams in their self-evaluations while retaining a necessary objectivity, and the difficulty of evaluating the moving target created by the developmental approach adopted in the initiative. An initial period to develop the evaluation protocol proved invaluable in helping us to explore these issues.

For physicians, feedback about their clinical practice and outcomes is central to developing both confidence and competence at all stages of their medical careers. Cultural and financial infrastructures need to be in place, and the concept of feedback needs to be readily embraced and encouraged by clinical leadership and other stakeholders. The "buy-in" includes the expectation and view that feedback occurs on a routine basis, and those engaged in the process are both encouraged to participate and held accountable. Feedback must be part of an overarching quality improvement and physician education agenda; it is not meant to be an isolated, fragmented initiative that is typically undermined by lack of resources or systemic barriers to gaining improvement within programs. Effective feedback should be an integral part of clinical practice. Anesthesiologists and other perioperative physicians are identifying specialty-specific indicators that can be used when creating a broader quality improvement agenda. Placing a more immediate formal feedback strategy that focuses on goal-oriented behavior is rapidly becoming a mainstay. Physicians may use their individual feedback reports for reflection and designing personal development plans as lifelong learners and leaders in improving patient care.Keywords: physician education, outcomes measurement, performance improvement, anesthesiology

    1999-10-01

    The first collaborative statewide psychiatric quality improvement project, initiated by Louisiana Health Care Review, Inc, focused on the practice of inpatient electro-convulsive therapy (ECT) among Medicare patients. Data from the project indicated that the majority of Medicare patients receiving ECT were white females living at home, in good physical health, in their seventies, and with a diagnosis of major depression or major depression with psychotic features. The quality indicators for the project included: (documentation of) monitoring of cognitive side effects, monitoring of depressive target symptoms, ECT appropriateness, electrode placement, anesthesia evaluation, and dental examination. An additional indicator (administration of possibly detrimental medication during ECT) was developed based on the recommendation by the study group. At project conclusion, significant improvement occurred in all project indicators. ECT as practiced in the participating hospitals was effective and appropriate. Appropriateness was determined as depression refractory to two medication trails or an emergency due to severe suicidal ideation or physical deterioration secondary to malnutrition. Transient hypertension (13%) and cardiac dysrhythmia (3.5%) which resolved in the recovery period were the most frequent complications. PMID:10546434

    In recent years, the US health care industry has experienced a rapid growth of managed care, formation of networks, and an integration of hospitals. This paper provides new insights about the quality consequences of this dynamic in US hospital markets. I empirically investigate the impact of managed care and hospital competition on quality using in-hospital complications as quality measures. I use random and fixed effects, and instrumental variable fixed effect models using hospital panel data from up to 16 states in the 1992-1997 period. The paper has two important findings: First, higher managed care penetration increases the quality, when inappropriate utilization, wound infections and adverse/iatrogenic complications are used as quality indicators. For other complication categories, coefficient estimates are statistically insignificant. These findings do not support the straightforward view that increases in managed care penetration are associated with decreases in quality. Second, both higher hospital market share and market concentration are associated with lower quality of care. Hospital mergers have undesirable quality consequences. Appropriate antitrust policies towards mergers should consider not only price and cost but also quality impacts. PMID:12369060

  13. Improvement in the textural qualities of irradiated legumes

    International Nuclear Information System (INIS)

    The potential for use of gamma radiation processing to improve texture, hydration and cooking quality of pulses, particularly red gram, has been examined. The textural changes in irradiated pulses in terms of softening is measured by a texturometer, Radiation (1 Mrad) processing of pulses resulted in reduction of cooking time varying from 8 to 39%, red gram showing the maximum reduction. Initial higher hydration rate on soaking and cooking, stabilized on prolonged cooking and resulted in better and uniform texture of irradiated red gram. In the uncooked, irradiated (1 Mrad) sample, destruction of riboflavin was negligible, whereas thiamine and niacin showed about 7% loss. However, the vitamins were retained better in the samples irradiated and then cooked, compared to the corresponding control ones. (F.J.)

  14. Quality control of physician-performed mammography. Importance of original attempts to improve quality

    International Nuclear Information System (INIS)

    In order to perform effective breast cancer screening with mammography, family doctors should be encouraged to participate. At institutions without specific radiology technicians, physicians themselves are required to perform mammography and operate the equipment, otherwise it is difficult to consistently obtain good-quality mammograms. Our institutions have been given a grade ''A'' evaluation by the Central Committee for Quality Control of Mammographic Screening (CCQCMS), due largely to our own efforts and promotion. Here we report our experience in solving a number of problems that occurred during the establishment of our system. We used the SEPIO standard mammography apparatus with a MD-100/CM-H screen/filter system, and developed films using a TCX-202 automatic film processor. Problems due to asymmetry of the bilateral breasts and lack of retroglandular fat tissue space and inframammary folds seen on our initial mammograms were overcome by placing marks at the postion of the AEC sensor, and at both ends and the center of the film on a bucky table. We simplified the markers by removing several complicated ones. We tried to rectify areas of the image that were obscured due to the difference in size between the inside of the cassette and the screen. Physicians and a radiology technician attended a mammography study course once weekly, and attempted to improve the quality of mammograms and our reading ability by obtaining advice from members of the CCQCMS. Manufacturece from members of the CCQCMS. Manufacturers responded with considerable delay to our attempt to overcome the troublesome appearance of numerous microcalfication-like artifact shadows caused by screens. In conclusion, in order to perform effective breast cancer screening with mammography, we must obtain mammograms of good quality, for which it is necessary to always try to seek new ways of improving. At the same time, manufacturers need to respond quickly to queries and problems related to quality control. (author)

    Cryopreservation of fish sperm has been studied for decades at a laboratory (research) scale. However, high-throughput cryopreservation of fish sperm has recently been developed to enable industrial-scale production. This study treated blue catfish (Ictalurus furcatus) sperm high-throughput cryopreservation as a manufacturing production line and initiated quality assurance plan development. The main objectives were to identify: (1) the main production quality characteristics; (2) the process features for quality assurance; (3) the internal quality characteristics and their specification designs; (4) the quality control and process capability evaluation methods, and (5) the directions for further improvements and applications. The essential product quality characteristics were identified as fertility-related characteristics. Specification design which established the tolerance levels according to demand and process constraints was performed based on these quality characteristics. Meanwhile, to ensure integrity throughout the process, internal quality characteristics (characteristics at each quality control point within process) that could affect fertility-related quality characteristics were defined with specifications. Due to the process feature of 100% inspection (quality inspection of every fish), a specific calculation method, use of cumulative sum (CUSUM) control charts, was applied to monitor each quality characteristic. An index of overall process evaluation, process capacity, was analyzed based on in-control process and the designed specifications, which further integrates the quality assurance plan. With the established quality assurance plan, the process could operate stably and quality of products would be reliable. PMID:23872356

    MØller, M H; Larsson, H J

    2013-01-01

    BACKGROUND: Mortality and morbidity are considerable after treatment for perforated peptic ulcer (PPU). Since 2003, a Danish nationwide quality-of-care (QOC) improvement initiative has focused on reducing preoperative delay, and improving perioperative monitoring and care for patients with PPU. The present study reports the results of this initiative. METHODS: This was a nationwide cohort study based on prospectively collected data, involving all hospitals caring for patients with PPU in Denmark. Details of patients treated surgically for PPU between September 2004 and August 2011 were reported to the Danish Clinical Register of Emergency Surgery. Changes in baseline patient characteristics and in seven QOC indicators are presented, including relative risks (RRs) for achievement of the indicators. RESULTS: The study included 2989 patients. An increasing number fulfilled the following four QOC indicators in 2010-2011 compared with the first 2 years of monitoring: preoperative delay no more than 6 h (59·0 versus 54·0 per cent; P = 0·030), daily monitoring of bodyweight (48·0 versus 29·0 per cent; P < 0·001), daily monitoring of fluid balance (79·0 versus 74·0 per cent; P = 0·010) and daily monitoring of vital signs (80·0 versus 68·0 per cent; P < 0·001). A lower proportion of patients had discontinuation of routine prophylactic antibiotics (82·0 versus 90·0 per cent; P < 0·001). Adjusted 30-day mortality decreased non-significantly from 2005-2006 to 2010-2011 (adjusted RR 0·87, 95 per cent confidence interval 0·76 to 1·00), whereas the rate of reoperative surgery remained unchanged (adjusted RR 0·98, 0·78 to 1·23). CONCLUSION: This nationwide quality improvement initiative was associated with reduced preoperative delay and improved perioperative monitoring in patients with PPU. A non-significant improvement was seen in 30-day mortality.

    Full Text Available In recent years, pediatric health care has embraced the concept of quality improvement to improve patient outcomes. As quality improvement efforts are implemented, network collaboration (where multiple centers and practices implement standardized programs is a popular option. In a collaborative network, improvement in the conduct of structural, process and outcome quality measures can lead to improvements in overall health, and benchmarks can be used to assess and compare progress. In this review article, we provided an overview of the quality improvement movement and the role of quality indicators in this movement. We reviewed current quality improvement efforts in pediatric inflammatory bowel disease (IBD, as well as other pediatric chronic illnesses. We discussed the need to standardize the development of quality indicators used in quality improvement networks to assess medical care, and the validation techniques which can be used to ensure that process indicators result in improved outcomes of clinical significance. We aimed to assess current quality improvement efforts in pediatric IBD and other diseases, such as childhood asthma, childhood arthritis, and neonatal health. By doing so, we hope to learn from their successes and failures and to move the field forward for future improvements in the care provided to children with IBD.

    Despite rising and unsustainable US health care costs, many stakeholders feel that the quality of medical services is limited and inconsistent. Value-based reforms are touted as the key to achieving health care system sustainability. Health care value is defined as quality delivered divided by cost incurred. Unfortunately, quality in health care is difficult to accurately define and methods to reliably assess and report health care quality are often lacking. Clinical registries have emerged as important mechanisms to define, measure, and promote health care quality. The purpose of this article is to describe the role of registries in neurosurgical quality improvement. PMID:25771281

    Full Text Available Certain difficulties are inherent in the implementation of the improvement of the quality of service, particularly in the Design Management Department. There is often a difference on the issue of translating vision between senior management and Design Department for service improvement into effective, operational QI programs. Middle managers have a key role to play, but often they are overlooked which leads to undermining their efforts to improve the quality programs offered by senior management. This paper describes the first phase of a PhD research project to determine and develop the role of middle management in successful implementation of quality management programs. A framework for quality improvement implementation, including key issues of importance to middle managers regarding their proactive involvement in QI, is suggested. Finally, the initial implementation of the model in a company is discussed.

    2012-03-01

    Laser micro-polishing (L?P) is a new laser-based microfabrication technology for improving surface quality during a finishing operation and for producing parts and surfaces with near-optical surface quality. The L?P process uses low power laser energy to melt a thin layer of material on the previously machined surface. The polishing effect is achieved as the molten material in the laser-material interaction zone flows from the elevated regions to the local minimum due to surface tension. This flow of molten material then forms a thin ultra-smooth layer on the top surface. The L?P is a complex thermo-dynamic process where the melting, flow and redistribution of molten material is significantly influenced by a variety of process parameters related to the laser, the travel motions and the material. The goal of this study is to analyze the impact of initial surface parameters on the final surface quality. Ball-end micromilling was used for preparing initial surface of samples from H13 tool steel that were polished using a Q-switched Nd:YAG laser. The height and width of micromilled scallops (waviness) were identified as dominant parameter affecting the quality of the L?Ped surface. By adjusting process parameters, the Ra value of a surface, having a waviness period of 33 ?m and a peak-to-valley value of 5.9 ?m, was reduced from 499 nm to 301 nm, improving the final surface quality by 39.7%.

The purpose of this paper is to describe the development of a statewide registry-based quality improvement collaborative in Michigan. Methods: The Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI was started in 2011 to improve the quality of care for total hip and knee replacement patients in Michigan. It is funded by Blue Cross and Blue Shield of Michigan/Blue Care Network as part of their Collaborative Quality Initiative (CQI program. The CQI concept depends on capturing high-quality data (clinical status, process, and outcome, rigorously developing risk-adjustment models, and presenting risk-adjusted data to collaborative members at four face-to-face meetings a year. Results: MARCQI has grown to include 44 hospitals and 377 orthopedic surgeons. The registry contains 54,848 cases (18,421 hips and 36,427 knees. Four collaborative-wide quality improvement activities have been initiated: 1 transfusion reduction, 2 deep vein thrombosis and pulmonary emboli prevention, 3 infection prevention, and 4 readmission prevention. Conclusion: The CQI model developed by Blue Cross and Blue Shield of Michigan/Blue Care Network can be adapted to hip and knee arthroplasty, which demonstrates that private payers can play a role in the development and promotion of arthroplasty registries in the United States.

  13. Nuclear Regulatory Commission initiative for technical specification improvement

    International Nuclear Information System (INIS)

    From early 1982 through 1984, the NRC, with industry's attention, engaged in several initiatives and studies to improve technical specifications. These activities resulted in the February 1987 interim Commission Policy Statement on Technical Specifications Improvements. The policy statement focused on the purpose of technical specifications to identify features that are of controlling importance to safety and to establish on them conditions to assure safe operation that cannot be changed without prior commission approval. The NRC reviewed industry's-represented by the Nuclear Management Resources Council, the four nuclear steam supply system owners' groups, and several of their member utilities-application of the interim policy statement's criteria to standard technical specifications (STSs). As a result, a split was established in May 1988: ?40% of the current limiting condition for operations (LCO) and surveillance requirements were identified as candidates for relocation to other documents such as the final safety analysis report (FSAR), programs, or procedures. The new STSs are to be living documents. As the NRC and industry continue to gain experience, additional improvements are to be made to the STSs. The guidance of the final policy statement is to be used to screen future generic items for inclusion in technical specifications

    2003-12-01

    This paper summarizes the results of a recent report on diabetes in Tennessee. Diabetes has reached epidemic proportions in Tennessee. In 2001, an estimated 7.7% of the population was diabetic, an increase from 5.8% a decade earlier. This increase is largely due to widespread unhealthy eating habits, physical inactivity, and associated obesity. The majority of diabetes is preventable and can be effectively treated through daily exercise and a healthy diet. Diabetes prevention efforts in Tennessee schools and communities, however, are grossly inadequate. Providers and payers underemphasize prevention. Since the causes of diabetes can be traced to childhood habits, early prevention is the key to reversing the diabetes epidemic. Immediate statewide action must be taken to promote daily exercise and decrease access to high-calorie, high-fat "junk" food in our schools and communities. Physicians, health professional organizations, health plans, government, churches, schools, and employers must work together to battle the diabetes epidemic through public education, community-wide health promotion programs, and efforts to improve quality of diabetes care for all Tennesseans.

    Wegener, Henrik Caspar

    2010-01-01

    During the last two decades the major food safety problems in Denmark, as determined by the number of human patients, has been associated with bacterial infections stemming from meat products and eggs. The bacterial pathogens causing the majority of human infections has been Salmonella and Campylobacter, and to a lesser extent Yersinia, Escherichia coli O157 and Listeria. Danish initiatives to improve the safety of meat products have focused on the entire production chain from the farm to the consumer, with a special emphasis on the pre-harvest stage of production. The control of bacterial pathogens which are resistant to antibiotics has been a new area of attention in the recent decade, and recently, the increasing globalization of the domestic food supply has called for a complete rethinking of the national food safety strategies. The implementations of a ‘‘case-by-case” risk assessment system, as well as increased international collaboration on surveillance, are both elements in this new strategy.

    Full Text Available The work on the quality improvement of fuel oil using acid treatment was carried out. The improvement of the fuel oil was done using sulphuric acid to remove contaminants. Sulphuric acid at different concentrations were mixed with the oil and kept at 45°C for four hours in the agitator vessel to allow reaction to take place. Acidic sludge was then drained off from the agitator and the oil was neutralized with sodium hydroxide. Centrifugation operation was used to extract the sulphonate dispersed in the oil. The treated and untreated oils were characterized for various properties and the results showed that the viscosity, total sulphur of fuel oil decreased from 6.0 to before 5.0 cst after acid treatment and 2.57 to 1.2225% w/w respectively while the flash point increased from 248 to 264°F. The water and sediment content increased from trace before to 0.6 after treatment. In addition, the calorific value increased from initial value of 44,368 to 44,805 and 44,715 kJ/kg at 50% and 75% conc. H2SO4 while decreasing with 85% and 90% conc. H2SO4.

  3. Process safety improvement-Quality and target zero

    International Nuclear Information System (INIS)

    Process safety practitioners have adopted quality management principles in design of process safety management systems with positive effect, yet achieving safety objectives sometimes remain a distant target. Companies regularly apply tools and methods which have roots in quality and productivity improvement. The 'plan, do, check, act' improvement loop, statistical analysis of incidents (non-conformities), and performance trending popularized by Dr. Deming are now commonly used in the context of process safety. Significant advancements in HSE performance are reported after applying methods viewed as fundamental for quality management. In pursuit of continual process safety improvement, the paper examines various quality improvement methods, and explores how methods intended for product quality can be additionally applied to continual improvement of process safety. Methods such as Kaizen, Poke yoke, and TRIZ, while long established for quality improvement, are quite unfamiliar in the process safety arena. These methods are discussed for application in improving both process safety leadership and field work team performance. Practical ways to advance process safety, based on the methods, are given

    Improving quality of care and maximizing efficiency are priorities in hip and knee replacement, where surgical demand and costs increase as the population ages. The authors describe the integrated structure and processes from the Continuous Quality Improvement (CQI) Program for Hip and Knee Replacement Surgical Care and summarize lessons learned from implementation. The Triple Aim framework and 6 dimensions of quality care are overarching constructs of the CQI program. A validated, evidence-based clinical pathway that measures quality across the continuum of care was adopted. Working collaboratively, multidisciplinary experts embedded the CQI program into everyday practices in clinics across Alberta. Currently, 83% of surgeons participate in the CQI program, representing 95% of the total volume of hip and knee surgeries. Biannual reports provide feedback to improve care processes, infrastructure planning, and patient outcomes. CQI programs evaluating health care services inform choices to optimize care and improve efficiencies through continuous knowledge translation. PMID:24958157

  5. Improving Software Quality through Program Analysis

    International Nuclear Information System (INIS)

    In this paper, we present the Program Analysis Framework (PAF) to analyze the software architecture and software modularity of large software packages using techniques in Aspect Mining. The basic idea about PAF is to record the call relationships information among the important elements firstly and then use the different analysis algorithms to find the crosscutting concerns which could destroy the modularity of the software from this recording information. We evaluate our framework through analyzing DATE, the ALICE Data-Acquisition (DAQ) software which handles the data flow from the detector electronics to the permanent storage archiving. The analysis results prove the effectiveness and efficiency of our framework. PAF has pinpointed a number of possible optimizations which could be applied and help maximizing the software quality. PAF could also be used for the analysis of other projects written in C language.

    Science.gov (United States)

    There are three basic strategies to improve indoor air quality: source control, improved ventilation, and air cleaners. This site offers the reader some insights to improving air quality through increased ventilation, air cleaners for particle removal, and other common sense methods that may be employed. Many times the quality of the air in our homes and public or office buildings is marginal at best. The sources of indoor pollution may be outside of our ability to rectify or it may be as simple as adjusting the flame on our furnace or kitchen stove or maybe something as simple as opening a door or window. However, in many instances we have no control over the air quality because of the materials used in the construction of the building.

  10. Improving initial polyp candidate extraction for CT colonography

    International Nuclear Information System (INIS)

    Reducing the number of false positives (FPs) as much as possible is a challenging task for computer-aided detection (CAD) of colonic polyps. As part of a typical CAD pipeline, an accurate and robust process for segmenting initial polyp candidates (IPCs) will significantly benefit the successive FP reduction procedures, such as feature-based classification of false and true positives (TPs). In this study, we introduce an improved scheme for segmenting IPCs. It consists of two main components. One is geodesic distance-based merging, which merges suspicious patches (SPs) for IPCs. Based on the merged SPs, another component, called convex dilation, grows each SP beyond the inner surface of the colon wall to form a volume of interest (VOI) for that IPC, so that the inner border of the VOI beyond the colon inner surface could be segmented as convex, as expected. The IPC segmentation strategy was evaluated using a database of 50 patient studies, which include 100 scans at supine and prone positions with 84 polyps and masses sized from 6 to 35 mm. The presented IPC segmentation strategy (or VOI extraction method) demonstrated improvements, in terms of having no undesirably merged true polyp and providing more helpful mean and variance of the image intensities rooted from the extracted VOI for classification of the TPs and FPs, over two other VOI extraction methods (i.e. the conventional method of Nappi and Yoshida (2003 Med. Phys. 30 1592-601) and our previous method (Zhu et 1592-601) and our previous method (Zhu et al 2009 Cancer Manag. Res. 1 1-13). At a by-polyp sensitivity of 0.90, these three methods generated the FP rate (number of FPs per scan) of 4.78 (new method), 6.37 (Nappi) and 7.01 (Zhu) respectively.

    2014-12-01

    Continuous data collection and analysis have been shown essential to achieving improvement in healthcare. However, the data required for local improvement initiatives are often not readily available from hospital Electronic Health Record (EHR) systems or not routinely collected. Furthermore, improvement teams are often restricted in time and funding thus requiring inexpensive and rapid tools to support their work. Hence, the informatics challenge in healthcare local improvement initiatives consists of providing a mechanism for rapid modelling of the local domain by non-informatics experts, including performance metric definitions, and grounded in established improvement techniques. We investigate the feasibility of a model-driven software approach to address this challenge, whereby an improvement model designed by a team is used to automatically generate required electronic data collection instruments and reporting tools. To that goal, we have designed a generic Improvement Data Model (IDM) to capture the data items and quality measures relevant to the project, and constructed Web Improvement Support in Healthcare (WISH), a prototype tool that takes user-generated IDM models and creates a data schema, data collection web interfaces, and a set of live reports, based on Statistical Process Control (SPC) for use by improvement teams. The software has been successfully used in over 50 improvement projects, with more than 700 users. We present in detail the experiences of one of those initiatives, Chronic Obstructive Pulmonary Disease project in Northwest London hospitals. The specific challenges of improvement in healthcare are analysed and the benefits and limitations of the approach are discussed. PMID:24874182

  16. A systems thinking approach to the sustainability of quality improvement programmes

    Scientific Electronic Library Online (English)

    D.J., van Dyk; L., Pretorius.

    2014-01-01

    Full Text Available The challenge for organisations to continually provide the best return on investment for their shareholders has become increasingly difficult through globalisation of the market place. There are many responses a company could make to these challenges - for example, new product development, increased [...] market capitalisation, cost reduction initiatives, and quality management. This last response focuses on, but is not restricted to, customer satisfaction, continuous improvement, and environmental impact. Continuous improvement addresses waste in the business design and manufacturing processes, which could lead to improved profit margins. The sustainability of quality improvement programmes remains a challenge. Causality can be studied, using Six Sigma tools, to relate cause and effect. But these tools do not always allow the user to study and understand feedback from other factors, such as soft human issues, in the improvement process system, typically referred to as 'feedback causality'. System dynamics may improve this understanding. Quality improvement programmes in the heavy engineering manufacturing environment are not researched to the same degree as those in the automotive manufacturing environment. The purpose of this paper is to share results from research into the sustainability of quality improvement programmes, and the development of an appropriate system dynamics model, using qualitative case study data gathered and coded in a heavy engineering manufacturing environment.

    It has been said that you cannot improve what you cannot measure. At Eli Lilly and Company, measurement is one of the five pillars of Total Quality. Quality Assurance and Toxicology have partnered in the use of measures to drive improvements in both areas. Quality Assurance and Toxicology have embarked on a journey in Total Quality to achieve customer satisfaction and drive continuous improvement. Measurement in the research and development world has traditionally not been well received. Contrary to popular belief, we have found that many processes can be measured in the research and development environment. Measurement is critical to the continuous improvement of processes because improvements are made using data. In Quality Assurance and Toxicology, the initial measures were put in place to gather baseline data. As we learned from our measures, we customized them to align with all of our processes. This article describes the journey of measuring Quality Assurance and Toxicology, including highlights of implementation strategies and lessons learned along the way. PMID:7804620

  18. The software improvement process - tools and rules to encourage quality

    International Nuclear Information System (INIS)

    The Applications section of the CERN accelerator controls group has decided to apply a systematic approach to quality assurance (QA), the 'Software Improvement Process' - SIP. This process focuses on three areas: the development process itself, suitable QA tools, and how to practically encourage developers to do QA. For each stage of the development process we have agreed on the recommended activities and deliverables, and identified tools to automate and support the task. For example we do more code reviews. As peer reviews are resource intensive, we only do them for complex parts of a product. As a complement, we are using static code checking tools, like FindBugs and Checkstyle. We also encourage unit testing and have agreed on a minimum level of test coverage recommended for all products, measured using Clover. Each of these tools is well integrated with our IDE (Eclipse) and give instant feedback to the developer about the quality of their code. The major challenges of SIP have been to 1) agree on common standards and configurations, for example common code formatting and Javadoc documentation guidelines, and 2) how to encourage the developers to do QA. To address the second point, we have successfully implemented 'SIP days', i.e. one day dedicated to QA work to which the whole group of developers participates, and 'Top/Flop' lists, clearly indicating the best and worst products with regards to SIP guidelines and standards, for example test coverage. This paper ps, for example test coverage. This paper presents the SIP initiative in more detail, summarizing our experience since two years and our future plans. (authors)

    CERN Document Server

    Maier, Viktor

    Physicists use self-written software as a tool to fulfill their tasks and often the developed software is used for several years or even decades. If a software product lives for a long time, it has to be changed and adapted to external influences. This implies that the source code has to be read, understood and modified. The same applies to the software of the Optics Measurements and Corrections (OMC) team at CERN. Their task is to track, analyze and correct the beams in the LHC and other accelerators. To solve this task, they revert to a self-written software base with more than 150,000 physical lines of code. The base is subject to continuous changes as well. Their software does its job and is effective, but runs regrettably not efficient because some parts of the source code are in a bad shape and has a low quality. The implementation could be faster and more memory efficient. In addition it is difficult to read and understand the code. Source code files and functions are too big and identifiers do not rev...

    2010-04-01

    The purposes of this study were to assess hospital foodservice quality and to identify causes of quality problems and improvement strategies. Based on the review of literature, hospital foodservice quality was defined and the Hospital Foodservice Quality model was presented. The study was conducted in two steps. In Step 1, nutritional standards specified on diet manuals and nutrients of planned menus, served meals, and consumed meals for regular, diabetic, and low-sodium diets were assessed in three general hospitals. Quality problems were found in all three hospitals since patients consumed less than their nutritional requirements. Considering the effects of four gaps in the Hospital Foodservice Quality model, Gaps 3 and 4 were selected as critical control points (CCPs) for hospital foodservice quality management. In Step 2, the causes of the gaps and improvement strategies at CCPs were labeled as "quality hazards" and "corrective actions", respectively and were identified using a case study. At Gap 3, inaccurate forecasting and a lack of control during production were identified as quality hazards and corrective actions proposed were establishing an accurate forecasting system, improving standardized recipes, emphasizing the use of standardized recipes, and conducting employee training. At Gap 4, quality hazards were menus of low preferences, inconsistency of menu quality, a lack of menu variety, improper food temperatures, and patients' lack of understanding of their nutritional requirements. To reduce Gap 4, the dietary departments should conduct patient surveys on menu preferences on a regular basis, develop new menus, especially for therapeutic diets, maintain food temperatures during distribution, provide more choices, conduct meal rounds, and provide nutrition education and counseling. The Hospital Foodservice Quality Model was a useful tool for identifying causes of the foodservice quality problems and improvement strategies from a holistic point of view. PMID:20461206

    OpenAIRE

    Diffley, John F. X.

    2011-01-01

    Origins of DNA replication must be regulated to ensure that the entire genome is replicated precisely once in each cell cycle. In human cells, this requires that tens of thousands of replication origins are activated exactly once per cell cycle. Failure to do so can lead to cell death or genome rearrangements such as those associated with cancer. Systems ensuring efficient initiation of replication, while also providing a robust block to re-initiation, play a crucial role in genome stability....

    Capps, Gregory

    Semiconductor products are manufactured and consumed across the world. The semiconductor industry is constantly striving to manufacture products with greater performance, improved efficiency, less energy consumption, smaller feature sizes, thinner gate oxides, and faster speeds. Customers have pushed towards zero defects and require a more reliable, higher quality product than ever before. Manufacturers are required to improve yields, reduce operating costs, and increase revenue to maintain a competitive advantage. Opportunities exist for integrated circuit (IC) customers and manufacturers to work together and independently to reduce costs, eliminate waste, reduce defects, reduce warranty returns, and improve quality. This project focuses on electrical over-stress (EOS) and re-test okay (RTOK), two top failure return mechanisms, which both make great defect reduction opportunities in customer-manufacturer relationship. Proactive continuous improvement initiatives and methodologies are addressed with emphasis on product life cycle, manufacturing processes, test, statistical process control (SPC), industry best practices, customer education, and customer-manufacturer interaction.

  4. Improvement of cassava cooking quality through mutation breeding

    International Nuclear Information System (INIS)

    Many high-yielding cassava varieties do not have the desired cooking quality. The objective of this project was to induce mutations to produce varieties with improved cooking quality while maintaining the disease-resistance and high-yielding characteristics. A cassava mutant (ISU-W) was obtained after irradiation of a variety from IITA with gamma rays and selection. Cuttings of the mutant were grown for 12 months in a field trial and investigated for tuber yield and cooking quality. Pest and disease incidence were monitored during the entire growth period. The results showed that the mutant retained the high-yield and disease resistant characters of the parent, and had improved cooking quality based on increased smoothness, mealiness and elasticity of the flour.

    Full Text Available Background: In 2002, the Ministry of Health (MoH of Botswana began its journey toward laboratory accreditation in an effort to enhance the quality of laboratory services. After a difficult start, the MoH recognised the need for a more practical and sustainable method for change that could be implemented nationally; they therefore adopted the Strengthening Laboratory Management Toward Accreditation (SLMTA programme. Objective: This study describes the process and lessons learned in implementing SLMTA and the role of supplemental training and mentoring so as to achieve Botswana’s national laboratory quality improvement goal. Methods: Eight laboratories were enrolled into the SLMTA programme in 2010, which included a series of workshops and improvement projects conducted over nine months. Four of these laboratories received supplementary training and focused mentorship from the Botswana Bureau of Standards (BOBS. Laboratory performance was measured at baseline and exit using the World Health Organization Regional Office for Africa’s Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA checklist. One laboratory did not receive an exit audit and was thus excluded from the analysis. Results: An 18 percentage-point improvement was observed when comparing the median baseline score (53% to the median exit score (71% for the seven laboratories. Laboratories that received additional training and mentorship from BOBS improved 21 percentage points, whilst non-BOBS-mentored laboratories improved eight percentage points. Hospital management buy-in and strong laboratory staff camaraderie were found to be essential for the positive changes observed. Conclusion: SLMTA facilitated improvements in laboratory quality management systems, yielding immediate and measurable results. This study suggests that pairing the SLMTA programme with additional training and mentorship activities may lead to further increases in laboratory performance; and that SLMTA is a practical approach to extending quality improvement to MOH laboratories.

    Quality measurement in health care is complex and in a constant state of evolution. Different approaches are necessary depending on the purpose of the measurement (e.g., accountability, research, improvement). Recent changes in health care accreditation standards are driving increased attention to measurement of the quality of pain management for improvement purposes. The purpose of this article is to determine what indicators are being used for pain quality improvement, compare results across studies, and provide specific recommendations to simplify and standardize future measurement of quality for hospital-based pain management initiatives. Pain management quality improvement monitoring experience and data from 1992 to 2001 were analyzed from 20 studies performed at eight large hospitals in the United States. Hospitals included: the University of Wisconsin Hospital and Clinics, Madison; Texas Medical Center, Houston; McAllen Medical Center, McAllen, TX; San Francisco General Hospital, San Francisco; Rush-Presbyterian-St. Luke's Medical Center and Northwestern Memorial Hospital, Chicago, IL; Memorial Sloan Kettering Cancer Center, New York; and Kaiser Sunnyside Medical Center of Kaiser Permanente Northwest, Clackamas, OR. Analyses of data led to consensus on six quality indicators for hospital-based pain management. These indicators include: the intensity of pain is documented with a numeric or descriptive rating scale; pain intensity is documented at frequent intervals; pain is treated by a route other than intramuscular; pain is treated with regularly administered analgesics, and when possible, a multimodal approach is used; pain is prevented and controlled to a degree that facilitates function and quality of life; and patients are adequately informed and knowledgeable about pain management. Although there are no perfect measures of quality, longitudinal data support the validity of a core set of indicators that could be used to obtain benchmark data for quality improvement in pain management in the hospital setting.

    2014-12-01

    The planning phases of quality improvement projects are commonly overlooked. Disorganized planning and implementation can escalate chaos, intensify resistance to change, and increase the likelihood of failure. Two important steps in the planning phase are (1) assessing local resources available to aid in the quality improvement project and (2) evaluating the culture in which the desired change is to be implemented. Assessing local resources includes identifying and engaging key stakeholders and evaluating if appropriate expertise is available for the scope of the project. This process also involves engaging informaticists and gathering available IT tools to plan and automate (to the extent possible) the data-gathering, analysis, and feedback steps. Culture in a department is influenced by the ability and willingness to manage resistance to change, build consensus, span boundaries between stakeholders, and become a learning organization. Allotting appropriate time to perform these preparatory steps will increase the odds of successfully performing a quality improvement project and implementing change. PMID:25467724

    Objectives To examine the effectiveness of the quality management programme—European Practice Assessment—in primary care in Switzerland. Design Longitudinal study with three points of measurement. Setting Primary care practices in Switzerland. Participants In total, 45 of 91 primary care practices completed European Practice Assessment three times. Outcomes The interval between each assessment was around 36?months. A variance analyses for repeated measurements were performed for all 129 quality indicators from the domains: ‘infrastructure’, ‘information’, ‘finance’, and ‘quality and safety’ to examine changes over time. Results Significant improvements were found in three of four domains: ‘quality and safety’ (F=22.81, pfinance’ (F=4.073, p<0.02). The 129 quality indicators showed a significant improvement within the three points of measurement (F=33.864, p<0.01). Conclusions The European Practice Assessment for primary care practices thus provides a functioning quality management programme, focusing on the sustainable improvement of structural and organisational aspects to promote high quality of primary care. The implementation of a quality management system which also includes a continuous improvement process would give added value to provide good care. PMID:25900466

    2013-01-01

    Clinical laboratories play an important role in improving patient care. The past decades have seen unbelievable, often unpredictable improvements in analytical performance. Although the seminal concept of the brain-to-brain laboratory loop has been described more than four decades ago, there is now a growing awareness about the importance of extra-analytical aspects in laboratory quality. According to this concept, all phases and activities of the testing cycle should be assessed, monitored and improved in order to decrease the total error rates thereby improving patients' safety. Clinical Chemistry and Laboratory Medicine (CCLM) not only has followed the shift in perception of quality in the discipline, but has been the catalyst for promoting a large debate on this topic, underlining the value of papers dealing with errors in clinical laboratories and possible remedies, as well as new approaches to the definition of quality in pre-, intra-, and post-analytical steps. The celebration of the 50th anniversary of the CCLM journal offers the opportunity to recall and mention some milestones in the approach to quality and patient safety and to inform our readers, as well as laboratory professionals, clinicians and all the stakeholders of the willingness of the journal to maintain quality issues as central to its interest even in the future.

    Anderson, C A; Cassidy, B; Rivenburgh, P

    1991-01-01

    Continuous Quality Improvement is in the process of being implemented in hospitals around the world. In an attempt to gain a better understanding of the "best management practices" the International Quality Study is being conducted in four countries--Canada, Germany, Japan and the United States--and across four industries--Health Care, Banking, Automotive and Computers. Information collected through a survey process will be analysed through causal modeling to determine correlations between management practices and achievement of quality objectives. Given both the complexity of the models and the number of key concepts involved, 400 hospitals have been invited to participate. The preliminary results show direct correlations between cultural influences and the concept of quality. The perceived definition of quality by the various countries varies and therefore the application of "quality concepts" differs. Once complete, this database of "best management practices" will serve as a worldwide benchmark for quality progress. PMID:1782382

  18. CT-guided biopsies. Quality, complications and impact on treatment. A retrospective initial quality control

    International Nuclear Information System (INIS)

    Purpose: To retrospectively evaluate the quality and complications of CT-guided biopsies and their impact on treatment. Materials and Methods: A total of 265 CT-guided interventions performed during a 6-month period were extracted by digital database query. These included 127 CT-guided biopsies, which were classified by patient age, organ/body area, histopathological biopsy diagnosis, complications, and performing physician. Results: In 51 % of cases (65/127), CT-guided biopsies led to a malignant diagnosis and a change in the patient's treatment. Retrospectively, complications were to be expected in a range of 12 - 26 %, given a 95 % confidence interval. In terms of organ/body area, most complications occurred in lung biopsies (23 / 56; 41 %). 80 % of CT-guided biopsies were performed without complications. 2 of the 11 physicians performed 66 % of all biopsies (84 / 127) and had significantly fewer complications than the others. Patient age was a statistically significant factor for complications (p < 0.018) as well as for a malignant biopsy diagnosis (p < 0.009). Conclusion: Our initial quality control assessment suggests that frequent use of CT-guided biopsy by the performing physician rather than the general level of experience is associated with fewer complications for patients. Age is a significant factor for complications of CT-guided biopsies, thus leading to an increased risk/benefit ratio. As expected, age also significantly increases the risk of a malignantficantly increases the risk of a malignant biopsy result. Complications and malignant biopsy results were not significantly associated. CT-guided biopsies triggered a change in treatment in over 50 % of cases. (orig.)

  19. IMPROVING CONCEPTUAL DESIGN QUALITY : BY USE OF QFD & DFMA PROCESSES

    Bush, Stuart; Robotham, Antony John

    1999-01-01

    This paper will consider how Quality Function Deployment (QFD) and Design for Manufacture and Assembly (DFMA) processes can be used to improve the design quality of products at the concept stage. We appreciate that both QFD and DFMA are techniques that have been used for some time by mature product developers, and the successes achieved using each have been widely reported. Here, though, we will share our experiences of using these tools with novice designers, i.e. student engineers.The use of both QFD and DFMA has proven to be a valuable approach for ensuring that a balanced consideration of design quality is maintained in design project work. The projects described have been carried out with products manufactured by small to medium sized enterprises (SME's), where we have found significant opportunities for product improvement. The quantitative nature ofDFMA analysis results allows the novice designer to identify clear targets for design improvement and to measure the effectiveness of any new solution, whilst attention to QFD ensures customer requirements are still being satisfied.Often, SME's are not aware of many of the best design practices and so are not able to meet the demand for continuous improvement of their products. However, we consider that if novice designers are able to successfully utilise design tools like QFD and DFMA and achieve improvements in design quality, then SME’s have no excuses for ignoring the benefits they could bring to their own product development activity.

    2015-04-01

    We describe an evidence-based framework to define and assess the impact of quality improvement (QI) in public health. Developed to address programmatic and research-identified needs for articulating the value of public health QI in aggregate, this framework proposes a standardized set of measures to monitor and improve the efficiency and effectiveness of public health programs and operations. We reviewed the scientific literature and analyzed QI initiatives implemented through the Centers for Disease Control and Prevention's National Public Health Improvement Initiative to inform the selection of 5 efficiency and 8 effectiveness measures. This framework provides a model for identifying the types of improvement outcomes targeted by public health QI efforts and a means to understand QI's impact on the practice of public health.

    Smidstrup, Søren; Stokbro, Kurt; Jónsson, Hannes

    2014-01-01

    A method is presented for generating a good initial guess of a transition path between given initial and final states of a system without evaluation of the energy. An objective function surface is constructed using an interpolation of pairwise distances at each discretization point along the path and the nudged elastic band method then used to find an optimal path on this image dependent pair potential (IDPP) surface. This provides an initial path for the more computationally intensive calculations of the true minimum energy path using some method of choice for evaluating the energy and atomic forces, for example by ab initio or density functional theory. The optimal path on the IDPP surface is significantly closer to the true minimum energy path than a linear interpolation of the Cartesian coordinates and, therefore, reduces the number of iterations needed to reach convergence and averts divergence in the electronic structure calculations when atoms are brought too close to each other in the initial path. Th...

    Significant gaps in healthcare quality and outcomes can be reduced via quality improvement collaboratives (QICs), which improve care by leveraging data and experience from multiple organizations.The Children's Hospital Neonatal Consortium Collaborative Initiatives for Quality Improvement team developed an infrastructure for neonatal QICs. We describe the structure and components of an effective multi-institutional neonatal QIC that implemented the "SLUG Bug" project designed to reduce central line-associated bloodstream infections (CLABSIs).The operational infrastructure of SLUG Bug involved 17 tertiary care neonatal intensive care units with a goal to reduce CLABSI in high-risk neonates. Clinical Practice Recommendations were produced, and the Institute of Healthcare Improvement Breakthrough Series provided the framework for the collaborative. Process measures studied the effectiveness of the collaborative structure.CLABSI rates decreased by 20% during a 12-month study period. Compliance bundle reporting exceeded 80%. A QIC score of 2.5 or more ("improvement") was achieved by 94% of centers and a score 4 or more ("significant improvement") was achieved by 35%.Frequent interactive project meetings, well-defined project metrics, continual shared learning opportunities, and individual team coaching were key QIC success components.

    International Nuclear Information System (INIS)

    Grain legumes provide an essential part of the diet in developing countries in terms of protein. Besides increasing production also improving the grain quality would be an important objective. The paper discusses the methodology for protein improvement in seeds of pigeon pea. Variety Hy-2 was irradiated with 20, 25, 30 and 35 Kr of gamma radiation and the M2 population was screened for total sulfur content

  2. Improved initial guess for minimum energy path calculations

    International Nuclear Information System (INIS)

    A method is presented for generating a good initial guess of a transition path between given initial and final states of a system without evaluation of the energy. An objective function surface is constructed using an interpolation of pairwise distances at each discretization point along the path and the nudged elastic band method then used to find an optimal path on this image dependent pair potential (IDPP) surface. This provides an initial path for the more computationally intensive calculations of a minimum energy path on an energy surface obtained, for example, by ab initio or density functional theory. The optimal path on the IDPP surface is significantly closer to a minimum energy path than a linear interpolation of the Cartesian coordinates and, therefore, reduces the number of iterations needed to reach convergence and averts divergence in the electronic structure calculations when atoms are brought too close to each other in the initial path. The method is illustrated with three examples: (1) rotation of a methyl group in an ethane molecule, (2) an exchange of atoms in an island on a crystal surface, and (3) an exchange of two Si-atoms in amorphous silicon. In all three cases, the computational effort in finding the minimum energy path with DFT was reduced by a factor ranging from 50% to an order of magnitude by using an IDPP path as the initial path. The time required for parallel computations was reduced even more because of load imbalance when linear interpolation of Cartesian coordinates was used

    Full Text Available Defect investigation is an important tool for quality improvement as it identifies the root cause of errors and steps to be taken to eliminate these. In this paper, four cases of defect investigation are presented. The case studies cover link elevator, wing-fuselage attachment bolt, and stiff nut for Lakshya unmanned aerial vehicle. It was observed that the link elevator was discolourised even though the material used was the stainless steel. Investigations revealed that the stainless steel was heat-treated. In the case of leading edge, it was found that there was no provision for the location of a component in the tool, resulting in mismatch. Thread damage was noticed in wing-fuselage attachment bolts because of over tightening. All these studies resulted in improvement in the raw material bonding, inspection procedures, and fabrication methods, thus resulting in quality improvement.

    The management of inpatient hyperglycemia is a focus of quality improvement projects across many hospital systems while remaining a point of controversy among clinicians. The association of inpatient hyperglycemia with suboptimal hospital outcomes is accepted by clinical care teams; however, the clear benefits of targeting hyperglycemia as a mechanism to improve hospital outcomes remain contentious. Glycemic management is also frequently confused with efforts aimed at intensive glucose control, further adding to the confusion. Nonetheless, several regulatory agencies assign quality rankings based on attaining specified glycemic targets for selected groups of patients (Surgical Care Improvement Project (SCIP) measures). The current paper reviews the data supporting the benefits associated with inpatient glycemic control projects, the components of a successful glycemic control intervention, and utilization of the electronic medical record in implementing an inpatient glycemic control project.

    Large variations in the quality of cancer care are a matter of concern in the United States. Despite spending over 15% of our GNP on health care, more than any other country in the world, some cancer patients face significant risks of dying from their treatment precisely because of their choice of physician. The Institute of Medicine has reported that variations in the quality of cancer are large, and that low-experienced providers are more likely to provide a lower quality of medical care. Increased pressures to contain costs have led to concern that the quality and outcomes of cancer care may only worsen. One reaction to this situation is a greater reliance on "report cards." In an effort to address both quality and cost issues, providers are looking outside the health care sector for guidance for more acceptable alternatives to report cards, which are often viewed as punitive. The approach that they most often have selected recently is termed continuous quality improvement (CQI) or total quality management (TQM). In this article, we describe the potential benefits and drawbacks of CQI efforts in oncology, review experiences with four different CQI cancer programs, and make recommendations about future CQI efforts.

    The issue of sustainability is at the top of the political and societal agenda, being considered of extreme importance and urgency. Human individual action impacts the environment both locally (e.g., local air/water quality, noise disturbance) and globally (e.g., climate change, resource use). Urban environments represent a crucial example, with an increasing realization that the most effective way of producing a change is involving the citizens themselves in monitoring campaigns (a citizen science bottom-up approach). This is possible by developing novel technologies and IT infrastructures enabling large citizen participation. Here, in the wider framework of one of the first such projects, we show results from an international competition where citizens were involved in mobile air pollution monitoring using low cost sensing devices, combined with a web-based game to monitor perceived levels of pollution. Measures of shift in perceptions over the course of the campaign are provided, together with insights int...

    Dai, Junfei; Zhang, Song

    2014-11-01

    This paper intends to thoroughly evaluate the influences of different phase-shifting algorithms, and optimization directions, and initial patterns. For fair comparisons, we used the same number of iterations for optimization and the same size of optimization patches. The variables are optimization domain (i.e., phase and intensity domain), the step number of the phase-shifting algorithm (i.e.. three and four step), the initial pattern (i.e., Bayer dithered and error diffusion dithered pattern), and the optimization direction (i.e., top to bottom, bottom to top, left to right, and right to left). Our ultimate goal is to generate the best possible quality binary pattern after optimization and hopefully provides guidelines on optimization strategies. Our simulation results suggest that an exhaustive optimization is necessary in order to produce the best quality pattern.

    DEFF Research Database (Denmark)

    TØttenborg, Sandra SØgaard; Thomsen, Reimar W.

    2012-01-01

    OBJECTIVE: To examine whether the quality of care among Danish patients with chronic obstructive pulmonary disease (COPD) has improved since the initiation of a national multidisciplinary quality improvement program. METHODS: We conducted a nationwide, population-based prospective cohort study using data from the Danish Clinical Register of COPD (DrCOPD). Since 2008 the register has systematically monitored and audited the use of recommended processes of COPD care. RESULTS: Substantial improvements were observed for all processes of care and registration fulfillment increased to well above 85% for all indicators. Compared to 2008, a higher proportion of COPD outpatients in 2011 received annual measurements of the forced expiratory volume in one second in percent of predicted (FEV1% predicted) (RR 2.14, 95% CI, 2.09; 2.19), assessment of BMI (RR 2.24, 95% CI, 2.19; 2.29), assessment of dyspnea using the Medical Research Council (MRC) scale (RR 2.25, 95% CI, 2.20; 2.31), registration of smoking status (RR2.41, 95% CI, 2.35; 2.47), smoking cessation recommendation (RR 3.40, 95% CI, 3.18; 3.64) and offering of pulmonary rehabilitation (RR 2.78, 95% CI, 2.65; 2.90). Moderate variation in quality of care fulfillment between regions and hospital clinics still existed in 2011. The proportion of patients with mild- to moderate COPD increased during the study period (p<0.0001). CONCLUSION: Based on increased registration practice of important processes of care, the present study indicates a substantial improvement in the quality of care of COPD in Danish hospitals following the initiation of a national multidisciplinary quality improvement program in 2008. In the forthcoming years, it will be interesting to observe if this will translate into a better prognosis of Danish patients with COPD.

    Peer, Kimberly S.; Rakich, Jonathon S.

    2000-01-01

    Objective: To apply the continuous quality improvement model commonly associated with the business sector to entrylevel athletic training education program accreditation. Data Sources: We applied athletic training educational program accreditation as a tool for ensuring quality in the entrylevel athletic training education programs accredited by the Commission on the Accreditation of Allied Health Education Programs. Literature from the business, education, and athletic training fields is integrated to support this paradigm shift in athletic training education. Data Synthesis: The advent of mandated entry-level athletic training educational program accreditation has forced institutions to evaluate their educational programs. Accreditation will promote continuous quality improvement in athletic training education through mechanisms such as control measures and process improvement. Conclusions/Recommendations: Although accreditation of entry-level athletic training education programs has created some dissonance among athletic training professionals, it will strengthen the profession as a whole. Athletic training educators must capture the synergy generated from this change to ensure quality educational experiences for all our students as we move forward to secure a strong position in the allied health care market.

    Buckner, M. R.

    Successful quality improvement requires a balanced program involving the three elements that control quality: organization, people and technology. The focus of the SPC/SPM User's Group is to advance the technology component of Total Quality by networking within the Group and by providing an outreach within Westinghouse to foster the appropriate use of statistic techniques to achieve Total Quality. SPM encompasses the disciplines by which a process is measured against its intrinsic design capability, in the face of measurement noise and other obscuring variability. SPM tools facilitate decisions about the process that generated the data. SPM deals typically with manufacturing processes, but with some flexibility of definition and technique it accommodates many administrative processes as well. The techniques of SPM are those of Statistical Process Control, Statistical Quality Control, Measurement Control, and Experimental Design. In addition, techniques such as job and task analysis, and concurrent engineering are important elements of systematic planning and analysis that are needed early in the design process to ensure success. The SPC/SPM User's Group is endeavoring to achieve its objectives by sharing successes that have occurred within the member's own Westinghouse department as well as within other US and foreign industry. In addition, failures are reviewed to establish lessons learned in order to improve future applications. In broader terms, the Group is interested in making SPM the accepted way of doing business within Westinghouse.

    Defining the quality of the university education system is not easy. Institutions of higher education, through curriculum are hoped to provide the knowledge, wisdom and personality of students. It is questionable of how far Quality and Productivity Improvement Program (PPKP) are capable to ensure the courses offered relevant and effective in preparing the students for job market. The effectiveness of a university to undertake responsibilities and the impact given to students even after they graduate can be a measure of education quality at university. So, the quality of education can be enhanced and improved from time to time. In general, this study is aims to determine the effectiveness of PPKP's education system from the perspective of their alumni as well as their satisfaction and the importance level based on how PPKP be able to meet their needs. In overall, summary of open-ended questions from the questionnaire, Importance-Performance analysis and correlation analysis were conducted for this study. Based on result, it appears that there are still some deficiencies that can be improve, particularly in terms of teaching skills and PPKP's relationships with external organizations to enable knowledge be channel effectively. Importance-Performance analysis highlights some topics or courses that should be offered by PPKP based on their importance in industrial practice. Summary of the results of correlation analysis was found that women are more positive and not too demanding compared to men. In addition, it is found that the responsibilities and workload of the older generations, higher income and a high level of experience demands them to use and practice what they have learned during their studies at PPKP. Results of this study are hoped could be used to improve the quality of education system at PPKP.

  19. Data quality objectives for the initial K West fuel examinations

    International Nuclear Information System (INIS)

    The Data Quality Objectives (DQOs) were established for the examinations of the first group of fuel samples shipped from the K West Basin to the Hanford 327 Building hot cells for examinations to support the Path Forward recommended to solve the safety and environmental concerns associated with the deteriorating fuel in the K Basins. A separate DQO will be prepared for each future shipment of samples to the hot cells. The material stored in the K West Basin must ultimately be removed from the basin and placed in a stable storage configuration until it can be disposed of in a repository. The condition of the fuel in the closed canisters is a major uncertainty for any of the proposed actions. The major question to answer is what are the conditions of the materials in the closed canisters? The data to be gathered during the canister opening, handling, transport, associated hot cell handling, and examinations will also support decisions related to the Path Forward primarily in areas of transportation and the Multi-Canister Overpack (MCO) design

  1. Accounting for Quality : On the Relationship Between Accounting and Quality Improvement in Healthcare

    DEFF Research Database (Denmark)

    Pflueger, Dane

    2015-01-01

    Background: Accounting-that is, standardized measurement, public reporting, performance evaluation and managerial control-is commonly seen to provide the core infrastructure for quality improvement in healthcare. Yet, accounting successfully for quality has been a problematic endeavor, often producing dysfunctional effects. This has raised questions about the appropriate role for accounting in achieving quality improvement. This paper contributes to this debate by contrasting the specific way in which accounting is understood and operationalized for quality improvement in the UK National Health Service (NHS) with findings from the broadly defined ‘social studies of accounting’ literature and illustrative examples. Discussion: This paper highlights three significant differences between the way that accounting is understood to operate in the dominant health policy discourse and recent healthcare reforms, and in the social studies of accounting literature. It shows that accounting does not just find things out, but makes them up. It shows that accounting is not simply a matter of substance, but of style. And it shows that accounting does not just facilitate, but displaces, control. Summary: The illumination of these differences in the way that accounting is conceptualized helps to diagnose why accounting interventions often fail to produce the quality improvements that were envisioned. This paper concludes that accounting is not necessarily incompatible with the ambition of quality improvement, but that it would need to be understood and operationalized in new ways in order to contribute to this end. Proposals for this new way of advancing accounting are discussed. They include the cultivation of overlapping and even conflicting measures of quality, the evaluation of accounting regimes in terms of what they do to practice, and the development of distinctively skeptical calculative cultures.

  2. Improvement of image quality using interpolated projection in myocardial SPECT

    2010-10-01

    Full Text Available Introduction: Myocardial SPECT imaging is usually performed acquiring 32 views in 180 degree with equal steps of 5.625 degrees. Acquiring more images requires spending more time or injection of more activity to the patients. An idea to improve the quality reconstructed images without acquiring extra images is producing the extra images interpolating the data between adjacent projections. The aim of present study was investigation the feasibility of this idea. Methods: Obviously such investigation cannot be performed on real patient's data. Therefore, data were simulated using NCAT digital phantom and SimSET Monte Carlo code. The imaging was performed as usual, acquiring 32 views from right anterior oblique to left posterior oblique. The data were interpolated to construct 5 images between adjacent projections convert it into 187 projections. The simulation was performed again acquiring 187 images as the reference. The conventional, interpolated and reference data set were reconstructed and compared for improvement and degradation in quality of final images. The above procedure was repeated for phantoms representing different types of heart disease, different cardiac size and different count densities. Results: The results showed that Hermit interpolation technique produces better quality images comparing to other interpolation methods tested. Results also confirmed that streak artifacts decreases, signal to noise ratio and contrast increased due to increasing the number of samples. Conclusion: These results indicate that the physical properties of reconstructed images improve significantly. This directly must improve the lesions delectability of images. However the matter is still under investigation

    Full Text Available Background: The improvment of the quality of testing services in public laboratories is a high priority in many countries. Consequently, initiatives to train laboratory staff on quality management are being implemented, for example, the World Health Organization Regional Headquarters for Africa (WHO-AFRO Strengthening Laboratory Management Towards Accreditation (SLMTA. Mentorship may be an effective way to augment these efforts. Methods: Mentorship was implemented at four hospital laboratories in Lesotho, three districts and one central laboratory, between June 2009 and December 2010. The mentorship model that was implemented had the mentor fully embedded within the operations of each of the laboratories. It was delivered in a series of two mentoring engagements of six and four week initial and follow-up visits respectively. In total, each laboratory received 10 weeks mentorship that was separated by 6–8 weeks. Quality improvements were measured at baseline and at intervals during the mentorship using the WHO-AFRO Strengthening Laboratory Quality Improvement Process Towards Accreditation (SLIPTA checklist and scoring system. Results: At the beginning of the mentorship, all laboratories were at the SLIPTA zero star rating. After the initial six weeks of mentorship, two of the three district laboratories had improved from zero to one (out of five star although the difference between their baseline (107.7 and the end of the six weeks (136.3 average scores was not statistically significant (p = 0.25. After 10 weeks of mentorship there was a significant improvement in average scores (182.3; p = 0.034 with one laboratory achieving WHO-AFRO three out of a possible five star status and the two remaining laboratories achieving a two star status. At Queen Elizabeth II (QE II Central Laboratory, the average baseline score was 44%, measured using a section-specific checklist. There was a significant improvement by five weeks (57.2%; p = 0.021. Conclusion: The mentorship programme in this study resulted in significant measurable improvements towards preparation for the WHO-AFRO SLIPTA process in less than six months. We recommend that mentorship be incorporated into laboratory quality improvement and management training programmes such as SLMTA, in order to accelerate the progress of laboratories towards achieving accreditation.

    Skilled nursing facilities (SNFs) are organizations that represent complex adaptive systems, offering barriers to the implementation of quality improvement (QI) initiatives. The current article describes the authors' efforts to use the approach of reflective adaptive process to implement a new model of care (i.e., the Skilled Heart Unit Program) for effective heart failure (HF) care in one SNF. A team of stakeholders from the local hospital system and a local SNF was convened to design and implement this new model. Evaluation of the implementation processes confirmed the value of the implementation approach, which centered on team-based approaches, staff engagement, and flexibility of processes to respect the SNF's needs and culture. Interviews with facility staff and the administrator revealed their perceptions that the strategy resulted in better HF care, enhanced teamwork between staff and clinicians, and improved staff job satisfaction. This work provides a unique blueprint of strategic QI implementation for patients with HF in the SNF setting. [Journal of Gerontological Nursing, 41(5), 26-33.]. PMID:25531299

Also, quality aspects of services were prioritized as follows: keeping the appearance of hospital (the design), accountability, assurance, credibility and having empathy. Thus, the only thing which mattered most for all staff and managers of studied hospital was the appearance of hospital as well as its staff look. This can grasp a high percentage of patients' satisfaction. By referring to contradiction matrix, the most important principles of TRIZ model were related to tangible factors including principles No. 13 (discarding and recovering), 25 (self-service), 35 (parameter changes), and 2 (taking out). Furthermore, in addition to these four principles, principle No. 24 (intermediary) was repeated most among the others. By utilizing TRIZ, hospital problems can be examined with a more open view, Go beyond The conceptual framework of the organization and responded more quickly to patients ' needs. PMID:25560360

  10. Processes for Quality Improvements in Radiation Oncology Clinical Trials

    International Nuclear Information System (INIS)

    Quality assurance in radiotherapy (RT) has been an integral aspect of cooperative group clinical trials since 1970. In early clinical trials, data acquisition was nonuniform and inconsistent and computational models for radiation dose calculation varied significantly. Process improvements developed for data acquisition, credentialing, and data management have provided the necessary infrastructure for uniform data. With continued improvement in the technology and delivery of RT, evaluation processes for target definition, RT planning, and execution undergo constant review. As we move to multimodality image-based definitions of target volumes for protocols, future clinical trials will require near real-time image analysis and feedback to field investigators. The ability of quality assurance centers to meet these real-time challenges with robust electronic interaction platforms for imaging acquisition, review, archiving, and quantitative review of volumetric RT plans will be the primary challenge for future successful clinical trials

    HIVQUAL-US is a capacity-building quality initiative for federally-funded HIV primary care clinics. Since 2004, HIVQUAL-US has supported the formation of regional groups, geographically-clustered clinics that build quality management capacity through collective learning about quality improvement. The purpose of this qualitative study was to examine members' experiences participating in groups and their self-reported quality management and improvement outcomes related to HIV primary care. Interviews were conducted with a sample of three HIVQUAL-US coaches who facilitated 11 regional groups and with nine of the clinic representatives participating in the regional groups. The regional groups were heterogeneous in composition, focus and style, but shared common activities. Benefits included implementation of group quality improvement projects and opportunities for sharing activities and challenges. Improved performance in targeted areas, enhanced understanding/use of improvement methods, and increased quality management capacity were reported outcomes. Regional groups can effectively promote peer-to-peer learning, develop leadership, strengthen quality management capacity, and improve quality of care for the HIV population. PMID:22864496

  7. Improving image quality in portal venography with spectral CT imaging

    International Nuclear Information System (INIS)

    Objective: To investigate the effect of energy spectral CT on the image quality of CT portal venography in cirrhosis patients. Materials and methods: 30 portal hypertension patients underwent spectral CT examination using a single-tube, fast dual tube voltage switching technique. 101 sets of monochromatic images were generated from 40 keV to 140 keV. Image noise and contrast-to-noise ratio (CNR) for portal veins from the monochromatic images were measured. An optimal monochromatic image set was selected for obtaining the best CNR for portal veins. The image noise and CNR of the intra-hepatic portal vein and extra-hepatic main stem at the selected monochromatic level were compared with those from the conventional polychromatic images. Image quality was also assessed and compared. Results: The monochromatic images at 51 keV were found to provide the best CNR for both the intra-hepatic and extra-hepatic portal veins. At this energy level, the monochromatic images had about 100% higher CNR than the polychromatic images with a moderate 30% noise increase. The qualitative image quality assessment was also statistically higher with monochromatic images at 51 keV. Conclusion: Monochromatic images at 51 keV for CT portal venography could improve CNR for displaying hepatic portal veins and improve the overall image quality.

  8. Improvement of bacteriological quality of frozen chicken by gamma radiation

    International Nuclear Information System (INIS)

    The possible use of gamma irradiation at doses of 1.6 to 4.0 kGy to improve bacteriological quality of frozen chicken was investigated. The effects of gamma irradiation on salmonella viability in frozen chicken and on sensory quality of frozen chicken were also evaluated. D10-values for different isolated strains of salmonella in frozen chicken varied from 0.41 to 0.57 kGy. A dose of 4 kGy is required for a seven log cycle reduction of salmonella contamination in frozen chicken. Approximately 21 per cent of frozen chicken examined were contaminated with salmonella. Salmonella typhimurium, salmonella virchow, and salmonella java were predominant. Irradiation of frozen chicken at a minimum dose of 3.2 kGy eliminated salmonella, coliform, Escherichia coli, and Staphylococcus aureus and, in addition, reduced baterial load by 2 log cycles. Faecal streptococci was still present in a 3.2 kGy samples but in a very small percentage and the count was not over 100 colonies per g. Discoloring of chicken meat was noted after a 2 kGy treatment. The sensory quality of frozen chicken irradiated at 3 and 4 kGy tended to decrease during frozen storage but was within the acceptable range on a nine point hedonic scale even after eight months of frozen storage. Dosage at 3.2 kGy appeared to be sufficient for improving bacteriological quality of frozen chicken

  9. Improvement of bacteriological quality of frozen shrimp by gamma radiation

    International Nuclear Information System (INIS)

    The possible use of gamma irradiation at doses of 2 and 3 kGy to improve bacteriological quality of frozen shrimp was investigated. The effects of gamma irradiation on salmonella viability in frozen shrimp and on sensory quality of frozen shrimp were also evaluated. Treatment of frozen shrimp at 3 kGy reduced bacterial load by 2 log cycles and eliminated Enterobacteriaceae, E. coli, V. parahaemolyticus, and S. aureus. Coliform was still present in a 3 kGy treated samples but in a very small percentage and the count was less than 10 cell/g. Salmonella was not detected in either irradiated or non-irradiated frozen shrimp. A difference in radiation resistance was noted among five salmonella serotypes tested. S. lexington was the most resistant and S. anatum was the least resistant. Salmonella resistance was higher in frozen inoculated shrimp than in refrigerated inoculated shrimp. A dose of at least 4.2 kGy is required for a seven log cycle reduction of salmonella contamination in frozen shrimp. Off-flavors were produced in frozen shrimp irradiated at 4.2 kGy but diminished during subsequent frozen storage. However, irradiated frozen shrimp was of acceptable quality for at least four months. Dosage at 3 kGy appeared to be sufficient for improving bacteriological quality of frozen shrimp

    2012-11-01

    Full Text Available The aim of this work is to improve the power quality for Distributed Generation (DG with power storage system. Power quality is the combination of voltage quality and current quality. Power quality is the set of limits of electrical properties that allows electrical systems to function in their intended manner without significant loss of performance or life. The electrical power quality is more concerned issue. The main problems are stationery and transient distortions in the line voltage such as harmonics, flicker, swells, sags and voltage asymmetries. Distributed Generation (DG also called as site generation, dispersed generation, embedded generation, decentralized generation, decentralized energy or distributed energy, generates electricity from the many small energy sources. In recent years, micro electric power systems such as photovoltaic generation systems, wind generators and micro gas turbines, etc., have increased with the deregulation and liberalization of the power market. Under such circumstances the environment surrounding the electric power industry has become ever more complicated and provides high-quality power in a stable manner which becomes an important topic. Here DG is assumed to include Wind power Generation (WG and Fuel Cells (FC, etc. Advantages of this system are constant power supply, constant voltage magnitude, absence of harmonics in supply voltage, un-interrupted power supply. In this project the electric power qualities in two cases will be compared. Case I: With the storage battery when it is introduced. Case II: Without the storage battery. The storage battery executes the control that maintains the voltage in the power system. It will be found that the electric power quality will be improved, when storage battery is introduced. The model system used in this Project work is composed of a Wind Turbine, an Induction Generator, Fuel Cells, An Inverter and a Storage Battery. A miniature Wind Power Generator is represented by WG. A fuel cell module is represented by FC. Transmission lines will be simulated by resistors and coils. The combined length of the lines from synchronous generator to the load terminal is 1.5 km. This model will be simulated using MATLAB/SIMULINK.

    Full Text Available Objective: Effective strategies for implementation of the World Health Organization’s Surgical Safety Checklist (SSCL are not well characterized in resource-limited settings. Our objective was to utilize a systems-based quality improvement (QI approach to initially implement a single, high-priority item from the SSCL. Setting: Butaro Hospital, a rural district hospital in northern Rwanda. Methods: A surgical service QI team was formed and trained with support of local leadership and expatriate staff trained in QI methodology. The team identifid perioperative antibiotic administration as the fist SSCL area for improvement. Baseline performance was measured by sampled chart review of Cesarean sections. Using systems-based QI methods and the Model for Improvement, a protocol for choice and timing of perioperative antibiotics was identifid as the necessary intervention, developed, and then implemented. The impact on performance and spread of QI was measured. Results: At baseline, only 5.2% of Cesarean section patients received both correct choice and timing of a prophylactic antibiotic agent. After development of the protocol, appropriate choice and timing of antibiotic was observed in 61.7% of cases (p < 0.001. This initial QI initiative stimulated additional projects to implement other components of the SSCL and to improve quality of surgical and anesthetic care. Conclusions: Implementing one component of the SSCL using QI methodology focused on stakeholder engagement, measurement, and team-based development of iterative systems of improvements facilitated a cultural change at Butaro Hospital. Training and support in QI methods can create an environment in which the SSCL and other efforts for quality in surgical and anesthetic care can be more readily implemented.

  14. Partnering health disparities research with quality improvement science in pediatrics.

    2015-02-01

    Disparities in pediatric health care quality are well described in the literature, yet practical approaches to decreasing them remain elusive. Quality improvement (QI) approaches are appealing for addressing disparities because they offer a set of strategies by which to target modifiable aspects of care delivery and a method for tailoring or changing an intervention over time based on data monitoring. However, few examples in the literature exist of QI interventions successfully decreasing disparities, particularly in pediatrics, due to well-described challenges in developing, implementing, and studying QI with vulnerable populations or in underresourced settings. In addition, QI interventions aimed at improving quality overall may not improve disparities, and in some cases, may worsen them if there is greater uptake or effectiveness of the intervention among the population with better outcomes at baseline. In this article, the authors review some of the challenges faced by researchers and frontline clinicians seeking to use QI to address health disparities and propose an agenda for moving the field forward. Specifically, they propose that those designing and implementing disparities-focused QI interventions reconsider comparator groups, use more rigorous evaluation methods, carefully consider the evidence for particular interventions and the context in which they were developed, directly engage the social determinants of health, and leverage community resources to build collaborative networks and engage community members. Ultimately, new partnerships between communities, providers serving vulnerable populations, and QI researchers will be required for QI interventions to achieve their potential related to health care disparity reduction.

    1999-01-01

    Macroergonomics, which emerged historically after sociotechnical systems theory, quality management, and ergonomics, is presented as the basis for a needed integrative methodology. A macroergonomics methodology was presented in some detail to demonstrate how aspects of microergonomics, total quality management (TQM), and sociotechnical systems (STS) can be triangulated in a common approach. In the context of this methodology, quality and safety were presented as 2 of several important performance criteria. To demonstrate aspects of the methodology, 2 case studies were summarized with safety and quality performance results where available. The first case manipulated both personnel and technical factors to achieve a "safety culture" at a nuclear site. The concept of safety culture is defined in INSAG-4 (International Atomic Energy Agency, 1991). as "that assembly of characteristics and attitudes in organizations and individuals which establishes that, as an overriding priority, nuclear plant safety issues receive the attention warranted by their significance." The second case described a tire manufacturing intervention to improve quality (as defined by Sink and Tuttle, 1989) through joint consideration of technical and social factors. It was suggested that macroergonomics can yield greater performance than can be achieved through ergonomic intervention alone. Whereas case studies help to make the case, more rigorous formative and summative research is needed to refine and validate the proposed methodology respectively. PMID:10602647

    Pay-for-performance is being applied at the physician level to stimulate improvements in quality of care and cost efficiency; however, little is known about how physicians will respond. We interviewed physicians exposed to a financial incentive program in California to identify possible barriers to the successful application of financial incentives by exploring physicians' opinions of and experiences with pay-for-performance programs. Reasons physicians cited for quality deficiencies included insurance coverage limitations and lack of patient compliance, time, and proper physician oversight. Physicians believe that they play a significant role and have a moderate to high degree of control over quality of care and that it is important to self-monitor. Physicians expressed the need for accurate and timely data, peer comparisons, and more patient time, staff support, and consultations with colleagues to successfully monitor and deliver quality care. Many support increased pay for delivering high-quality care but question measurement accuracy, bonus payment financing, and health plan involvement. PMID:17077418

    Sheet metal manufacturers are under constant and increasing pressure to improve and document quality, while reducing cost. Furthermore, OEMs are shifting responsibility for quality inspections to suppliers, adding extra burdens. Exciting, shapely product designs are placing greater demands on both quality assurance and development departments. Deep drawing and other new advanced forming methods push materials to their limits. There is a new stamping quality control tool available for easy, effective and reliable determination of shape, strains and thinning. Full-field optical vision systems, based on the well-known principles of circle grid analysis and photogrammetry, provide automated analysis and quantitative color maps for every square inch of complex parts. Quality results are displayed on a 3D computer model, using the actual measured dimensions of the real part, allowing it to be viewed from any angle. One of the key features of this system is a dynamic link between the forming limit diagram and the strain/thinning color map. When a point is clicked on either display, a second crosshair automatically highlights that same point on the other display, and a detail box presents all measured and calculated quantities. Critical points can be identified at a glance so that corrective action can be taken. Examples shown include before and after die optimization, and analysis of a 1.2 meter long B-pillar stamping.

    Tumor-infiltrating immune cells can promote chemoresistance and metastatic spread in aggressive tumors. Consequently, the type and quality of immune responses present in the neoplastic stroma are highly predictive of patient outcome in several cancer types. In addition to host immune responses, intrinsic tumor cell activities that mimic stem cell properties have been linked to chemoresistance, metastatic dissemination, and the induction of immune suppression. Cancer stem cells are far from a static cell population; rather, their presence seems to be controlled by highly dynamic processes that are dependent on cues from the tumor stroma. However, the impact immune responses have on tumor stem cell differentiation or expansion is not well understood. In this study, we show that targeting tumor-infiltrating macrophages (TAM) and inflammatory monocytes by inhibiting either the myeloid cell receptors colony-stimulating factor-1 receptor (CSF1R) or chemokine (C-C motif) receptor 2 (CCR2) decreases the number of tumor-initiating cells (TIC) in pancreatic tumors. Targeting CCR2 or CSF1R improves chemotherapeutic efficacy, inhibits metastasis, and increases antitumor T-cell responses. Tumor-educated macrophages also directly enhanced the tumor-initiating capacity of pancreatic tumor cells by activating the transcription factor STAT3, thereby facilitating macrophage-mediated suppression of CD8(+) T lymphocytes. Together, our findings show how targeting TAMs can effectively overcome therapeutic resistance mediated by TICs. PMID:23221383

    Full Text Available Production systems have a special value since they are used in state-space searching algorithms and expert systems in addition to their use as a model for problem solving in artificial intelligence. Therefore, it is of high importance to consider different techniques to improve their performance. In this research, rule base is the component of the production system that we aim to focus on. This work therefore seeks to investigate this component and its relationship with other components and demonstrate how the improvement of its quality has a great impact on the performance of the production system as a whole. In this paper, the improvement of rule base quality is accomplished in two steps. The first step involves re-writing the rules having conjunctions of literals and producing a new set of equivalent rules in which long inference chains can be obtained easily. The second step involves augmenting the rule base with inference short-cut rules devised from the long inference chains. These inference short-cut rules have a great impact on the performance of the production system. Finally, simulations are performed on randomly generated rule bases with different sizes and goals to be proved. The simulations demonstrate that the suggested enhancements are very beneficial in improving the performance of production systems.

    Colonoscopy with polypectomy has been shown to reduce the risk of colon cancer. The critical element in the quality of colonoscopy in terms of polyp detection and removal continues to be the performance of the endoscopist, independent of patient-related factors. Improved results in terms of polyp detection and complete removal have implications regarding the development of screening and surveillance intervals and the reduction of interval cancers after negative colonoscopy. Advances in colonoscopy techniques such as high-definition colonoscopy, hood-assisted colonoscopy and dye-based chromoendoscopy have improved the detection of small and flat-type colorectal polyps. Virtual chromoendoscopy has not proven to improve polyp detection but may be useful to predict polyp pathology. The majority of polyps can be removed endoscopically. Available polypectomy techniques include cold forceps polypectomy, cold snare polypectomy, conventional polypectomy, endoscopic mucosal resection and endoscopic submucosal dissection. The preferred choice depends on the polyp size and characteristics. Other useful techniques include colonoscopic hemostasis for acute colonic diverticular bleeding, endoscopic decompression using colonoscopic stenting, and transanal tube placement for colorectal obstruction. Here we review the current knowledge concerning the improvement of quality measures in colonoscopy and colonoscopy-related therapeutic interventions. PMID:25278696

    Purpose - The purpose of this paper is to present an innovative quality improvement intervention developed in Morocco and discuss its implementation. Until 2004, the Moroccan Ministry of Health (MoH) encouraged pilots of quality improvement approaches but none of them were revealed to be sustainable. Internal assessments pinpointed factors such as lack of recognition of the participating team's efforts and lack of pressure on managers to become more accountable. In 2005, Morocco opted for an intervention called "Quality Contest" (QC) targeting health centres, hospitals and health district offices and combining quality measurement with structures ranking, performance disclosure and reward system. Design/methodology/approach - The QC is organized every 18 months. After the self-assessment and external audit step, the participating structures are ranked according to their scores. Their performances are then disseminated and the highest performing structures are rewarded. Findings - The results showed an improvement in performance among participating structures, constructive exchange of successful experiences between structures, as well as communication of constraints, needs and expectations between MoH managers at central and local levels; the use of peer-auditors was appreciated as it enabled an exchange of best practices between auditors and audited teams but this was mitigated by the difficulty of ensuring their neutrality; and the recognition of efforts was appreciated but seemed insufficient to ensure a sense of justice and maintain motivation. Originality/value - This intervention is an example of MoH leadership that has succeeded in introducing transparency and accountability mechanisms (ranking and performance disclosure) as leverage to change the management culture of the public health services; setting up a reward system to reinforce motivation and adapting continuously the intervention to enhance its sustainability and acceptability.

  5. Improving the hygienic quality of chicken through radiation processing

    International Nuclear Information System (INIS)

    Irradiation is considered one of the most efficient technological processes for the reduction of microorganisms in food, It can be used to improve the safety of food products, and to extend their shelf lives. The aim of this study was to improve the hygienic quality of chicken through radiation processing. As part of the study a microbial assessment of broiler chicken thighs from three retail outlets (supermarket, local markets and farms) was conducted. The total viable count and total coliform counts were determined. Hygienic quality indicator organisms such as Escherichia coli, Salmonella and Staphylococcus aureus were isolated and microbial counts made. Radiation sensitivity test to determine the D10 (decimal reduction does) of E. coli on chicken at refrigeration and frozen temperature were conducted. D10 values were 0.22 ± 0.02 and 0.32 ± 0.03 kGy at refrigerated and frozen temperatures respectively. A storage test consisting of an uninoculated pack experiment and a challenge test to explore the effect of irradiation and frozen food storage on the total viable count and survival of E. coli was conducted. Chicken thigh samples were treated with 0 (non irradiated), 2.0, 4.0, 6.0 and 8.0 kGy of gamma irradiation and held frozen for 56 days. The control and irradiated samples were stored at -18 oC and underwent microbial analysis and sensory evaluation at 7 days intervals. It was observed that irradiation and frozen storage reduced mirradiation and frozen storage reduced microbial loads. There were significant differences in sensory quality characteristics during freezing storage in chicken meat. The combination of irradiation and frozen storage resulted in greater overall reductions on microbial loads thus improving hygienic quality. (au)

    Despite the substantial progress in elucidating the pathophysiology of acute coronary syndromes (ACS) and developing an array of therapeutic advances for the management of these conditions, several challenges still persist. The use of guideline recommendations for the care of patients with ACS by both healthcare providers and hospitals can improve short-term and long-term outcomes and potentially reduce healthcare costs. However, evidence suggests that adherence to guidelines is suboptimal. Several quality improvement programs, by both governmental and nongovernmental organizations, have been developed in an attempt to encourage maximal utilization of evidence-based interventions. In this review, we will examine the evidence for the importance of guideline adherence in the management of ACS, explore predictors of adherence to these guidelines, and provide evidence-based strategies for improving their implementation.

  8. Improvement of tube low carbon steel quality during casting

    International Nuclear Information System (INIS)

    The effect was investigated of treatment by a complex modifier, an exothermic slag-forming mixture and m rocooling agents upon the quality of st. 20 steel and the morphology of nonmetallic inclusions in cast and rolled metal. It was shown that the treatment of molten steel by a complex modifier improves structure, reduces chemical and physical inhomogeneities, increases density of metal, contributes to a uniform distribution and a favourable shaping of oxide and sulfide inclusions, improves plastic properties and resilience in a direction perpendicular to that of rolling and minimizes anizotropy of properties. No appreciable improvements in properties of steel through treatment of molten metal by microcooling agents and exotehrmic mixture were observed

    What fraction of the black carbon arriving on Yala Glacier in Langtang, Nepal, is from cooking fires in the houses in the valley below? What fraction is from elsewhere in rural Nepal? What fraction is from industrial and transport sources in Kathmandu? What fraction is from northern India and beyond? What fraction is from the high altitude forest fires that take place during March or April? Effectively mitigating the impacts of black carbon and other short-lived climate forcers requires detailed understanding not just of emissions and impacts, but also of the atmospheric transport pathways that connect the two. In mountainous areas of the Hindu-Kush Himalaya detailed quantitative knowledge about emissions, atmospheric processes, and impacts is still largely missing. The International Centre for Integrated Mountain Development (ICIMOD) is an intergovernmental organization covering Afghanistan, Pakistan, India, Nepal, China, Bhutan, Bangladesh, and Myanmar. ICIMOD's recently established Atmosphere Initiative not only assesses mitigation options and contributes to policy and capacity building in the region, but also works actively to promote collaboration among researchers in the region, while building up an in-house team whose research will address key questions about SLCF. In Spring 2013 ICIMOD's Atmosphere Initiative, in collaboration with the Institute for Advanced Sustainability Studies (IASS) in Potsdam, Germany, carried out the largest field campaign to date in Nepal, hosting instruments belonging to dozens of institutions around the world, at nine field site within and upwind of the Kathmandu Valley, Nepal. The dataset that has been collected gives unprecedented insights into the emissions and atmospheric processes taking place downwind of and within the largest urban agglomeration in the Himalaya region. Meanwhile, in collaboration with national partner institutions, ICIMOD is in the process of setting up one atmospheric observatory each in Bhutan and in Nepal. Each will be on a mountain peak overlooking the Indo-Gangetic Plains. A building will house laboratories and visitor space, and will have a small tower. Each site will be equipped with a Picarro G2401 analyzer for CO, CO¬2, methane and water vapor, aerosol filter samplers, as well as instruments to measure black carbon, ozone, aerosol size distribution, aerosol scattering, cloud condensation nuclei, solar radiation, aerosol optical depth, and meteorology. Together with output from ICIMOD's new atmospheric modeling centre, the data from the sites will allow quantifying the flux of pollutants from the Indo-Gangetic Plains towards the high Himalaya, and to estimate emissions of SLCFs within the Himalayan foothills region. The infrastructure at both observatory sites is designed to accommodate training and future expansion as well as to host visiting instruments.

    Suzuki, Katsuhiro; Higuchi, Takeshi

    2007-03-01

    Many new methods have been introduced into routine laboratory works in microbiology since 1990. Molecular biology, in particular, opened a new era and promoted a technician's skill much. PCR and hybridization technique have been ordinary one in many laboratories. Since old techniques such as smear and culture are still needed, amount of routine works is increasing gradually. Thus, improving efficiency and keeping quality of routine works are becoming more and more important issues. This symposium focused on such points, and four skilled technicians around Japan presented their own tips. 1. Coexistence of M. tuberculosis and M. avium complex (MAC) in the MGIT culture system: Yasushi WATANABE (Clinical Laboratory Division, NHO Nishi-Niigata Chuo National Hospital). Sputum samples of some tuberculosis patients yielded only MAC in the MGIT culture system. Such co-infected cases presented problems to mislead proper treatment and infection control. The detection rate of MAC was significantly high, and the growth speed of MAC was significantly rapid in the MGIT culture system, compared to those of M. tuberculosis. Additionally, M. tuberculosis was not detected with even more quantity than MAC in the small amount of mixed samples. Higher sensitivity and growth speed of MAC are the important characteristics of the MGIT system. 2. Internal quality control with ordinary examination results: Akio AONO (Department of Clinical Examination, Double-Barred Cross Hospital, Japan Anti-Tuberculosis Association). Our laboratory utilizes ordinary examination results as the internal quality control for specimen pretreatment, culture, and drug susceptibility testing. The contamination rate of MGIT culture system is useful for the evaluation of the decontamination process. It was 6.3% on average in our laboratory in 2005. The number of drug resistant strains is also useful to assess the performance of drug susceptibility testing. The incidence of each anti-tuberculosis drug resistance detected monthly in 2005 is up to 5 for isoniazid (INH), 4 for rifampicin (RFP), 7 for streptomycin (SM), 1 for ethambutol (EB), and 2 for pyrazinamide (PZA), respectively. If any serious deviation from the average number is observed, action for the investigation is taken. The analysis of the ordinary examination data is useful to implement a quality control efficiently, and to improve the total laboratory performance. 3. The advanced devices for solving problems of the smears and cultivation of Mycobacteria: Motohisa TOMITA (NHO Kinki-chuo Chest Medical Center). Recently, the newly developed, standardized, commercially available kits including PCR and liquid media for confirmation and identification of mycobacteria are prevalent in Japan for the rapid diagnosis of M. tuberculosis. These tests are sensitive and accurate, but still expensive and technically demanding. The improvement of these methods, in particular, requires time-consuming process. We have optimized the culture technique, the identification method, and the drug-susceptibility testing for Mycobacteria in a time-saving manner. They should provide a basic grounding in the application of the techniques for anyone who is interested in these intriguing bacteria. 4. Ultimate quality control of specimens--teaching how to get a good sputum sample: Takeshi HIGUCHI (Kyoto University Hospital). Modern techniques including molecular biology have been applied to routine laboratory works for rapid detection, identification, and drug susceptibility testing of mycobacteria. Even in using such techniques, however, poor quality specimens yield only poor results. To get a high quality specimen, particularly sputum samples, is very important. Therefore, laboratory technicians in our hospital have directly taught each patient how to expectorate good quality sputa since 2001. The teaching of patients has improved the rate of P1 samples from 21.5% to 36.6% by Miller and Jones visual score of sputum. The teaching has also improved the rate of smear positive P1 samples from 11.4% to 28.8%. To teach each patient how to get go

    The Mexico City Air Quality Research Initiative has developed a methodology to assist decision makers in determining optimum pollution control strategies for atmospheric pollutants. The methodology introduces both objective and subjective factors in the comparison of various strategies for improving air quality. Strategies or group of options are first selected using linear programming. These strategies are then compared using Multi-Attribute Decision Analysis. The decision tree for the Multi-Attribute Decision Analysis was generated by a panel of experts representing the organizations in Mexico that are responsible for formulating policy on air quality improvement. Three sample strategies were analyzed using the methodology: one to reduce ozone by 33% using the most cost effective group of options, the second to reduce ozone by 43% using the most cost effective group of options and the third to reduce ozone by 43% emphasizing the reduction of emissions from industrial sources. Of the three strategies, the analysis indicated that strategy 2 would be the preferred strategy for improving air quality in Mexico City.

    Total Quality Management (TQM) is a cooperative form of doing business that relies on the talents of everyone in an organization to continually improve quality and productivity, using teams and an assortment of statistical and measurement tools. The objective of the activities described in this paper was to implement effective improvement tools and techniques in order to build work processes which support good management and technical decisions and actions which are crucial to the success of the ACRV project. The objectives were met by applications in both the technical and management areas. The management applications involved initiating focused continuous improvement projects with widespread team membership. The technical applications involved applying proven statistical tools and techniques to the technical issues associated with the ACRV Project. Specific activities related to the objective included working with a support contractor team to improve support processes, examining processes involved in international activities, a series of tutorials presented to the New Initiatives Office and support contractors, a briefing to NIO managers, and work with the NIO Q+ Team. On the technical side, work included analyzing data from the large-scale W.A.T.E.R. test, landing mode trade analyses, and targeting probability calculations. The results of these efforts will help to develop a disciplined, ongoing process for producing fundamental decisions and actions that shape and guide the ACRV organization .

    An ensemble data assimilation (DA) procedure is developed and evaluated for the Hydrologic Simulation Program - Fortran (HSPF), a widely used watershed water quality model. The procedure aims at improving the accuracy of short-range water quality prediction by updating the model initial conditions (IC) based on real-time observations of hydrologic and water quality variables. The observations assimilated include streamflow, biochemical oxygen demand (BOD), dissolved oxygen (DO), chlorophyll a (CHL-a), nitrate (NO3), phosphate (PO4) and water temperature (TW). The DA procedure uses the maximum likelihood ensemble filter (MLEF), which is capable of handling both nonlinear model dynamics and nonlinear observation equations, in a fixed-lag smoother formulation. For evaluation, the DA procedure was applied to the Kumho Catchment of the Nakdong River Basin in the Republic of Korea. A set of performance measures was used to evaluate analysis and prediction of streamflow and water quality variables. To remove systematic errors in the model simulation originating from structural and parametric errors, a parsimonious bias correction procedure is incorporated into the observation equation. The results show that the DA procedure substantially improves predictive skill for most variables; reduction in root mean square error ranges from 11% to 60% for Day-1 through 3 predictions for all observed variables except DO. It is seen that MLEF handles highly nonlinear hydrologic and biochemical observation equations very well, and that it is an effective DA technique for water quality forecasting.

  16. Improving the quality of manually acquired data: Applying the theory of planned behaviour to data quality

    International Nuclear Information System (INIS)

    The continued reliance of manual data capture in engineering asset intensive organisations highlights the critical role played by those responsible for recording raw data. The potential for data quality variance across individual operators also exposes the need to better manage this particular group. This paper evaluates the relative importance of the human factors associated with data quality. Using the theory of planned behaviour this paper considers the impact of attitudes, perceptions and behavioural intentions on the data collection process in an engineering asset context. Two additional variables are included, those of time pressure and operator feedback. Time pressure is argued to act as a moderator between intention and data collection behaviour, while perceived behavioural control will moderate the relationship between feedback and data collection behaviour. Overall the paper argues that the presence of best practice procedures or threats of disciplinary sanction are insufficient controls to determine data quality. Instead those concerned with improving the data collection performance of operators should consider the operator's perceptions of group attitude towards data quality, the level of feedback provided to data collectors and the impact of time pressures on procedure compliance. A range of practical recommendations are provided to those wishing to improve the quality of their manually acquired data.

    CONTEXT Previous studies testing continuous quality improvement (CQI) for depression showed no effects. Methods for practices to self-improve depression care performance are needed. We assessed the impacts of evidence-based quality improvement (EBQI), a modification of CQI, as carried out by 2 different health care systems, and collected qualitative data on the design and implementation process. OBJECTIVE Evaluate impacts of EBQI on practice-wide depression care and outcomes. DESIGN Practice-level randomized experiment comparing EBQI with usual care. SETTING Six Kaiser Permanente of Northern California and 3 Veterans Administration primary care practices randomly assigned to EBQI teams (6 practices) or usual care (3 practices). Practices included 245 primary care clinicians and 250,000 patients. INTERVENTION Researchers assisted system senior leaders to identify priorities for EBQI teams; initiated the manual-based EBQI process; and provided references and tools. EVALUATION PARTICIPANTS Five hundred and sixty-seven representative patients with major depression. MAIN OUTCOME MEASURES Appropriate treatment, depression, functional status, and satisfaction. RESULTS Depressed patients in EBQI practices showed a trend toward more appropriate treatment compared with those in usual care (46.0% vs 39.9% at 6 months, P = .07), but no significant improvement in 12-month depression symptom outcomes (27.0% vs 36.1% poor depression outcome, P = .18). Social functioning improved significantly (mean score 65.0 vs 56.8 at 12 months, P = .02); physical functioning did not. CONCLUSION Evidence-based quality improvement had perceptible, but modest, effects on practice performance for patients with depression. The modest improvements, along with qualitative data, identify potential future directions for improving CQI research and practice. PMID:16836631

  18. Improving Service Quality by Using Organizational Citizenship Behavior: Iranian Evidence

    2011-09-01

    Full Text Available Nowadays, with increasing service industries, service marketing and service quality have become an important challenge to organizations. The attempts of organizations in this situation are witnesses to this matter. In the past years, the organizations tried to reach service quality appropriation and satisfaction of self-external customers by concepts and approaches of external marketing. One of the important features of service is the direct interaction with customers and having customer-oriented behaviors. Furthermore, with introducing the internal marketing and the important roles of it, an internal customer of organizations, on achievement of organizational plans, was noted to internal marketing more and more than before. So, the study researchers are going to argue about internal marketing and the effect of it on organizational citizenship behaviors and service quality and the important role of it on development and improvement of service quality by using organizational citizenship behaviors. For this purpose, first the researchers have studied internal marketing and its important components and then have done the same to the other items and finally have applied a quantitative study on all of them. It should be mentioned that the researchers have employed SPSS 17.0 and Lisrel 8.54 for data analysis. The findings of the present study illustrated that there is an appropriate interaction among all the items, which has been studied here and the structural equations for the conceptual framework of this study are goodness of fit.

    Whitehead, Tim; Simmonds, David; Preston, John

    2006-07-01

    This paper is concerned with the link between urban quality improvements and economic activity. A key question is whether improvements in the urban environment which might be achieved, for instance, through pedestrianisation, will affect business location choices--for example, are office or retail businesses particularly keen to locate in more pleasant urban places? The paper outlines the current state of development of the literature with respect to the influence of urban quality on economic activity, and proposes a framework for forecasting economic impacts based on three communities of reference: customers, employees, and the businesses themselves. The results from original modelling of a case study area in Manchester, England are reported and suggest that the positive uplifts that may be expected from environmental improvement programmes may well be on a scale which is significant. The research is obviously important for the urban regeneration and renaissance agendas which posit attractive and well-designed environments as a way to create the right conditions for promoting economic growth.

  20. Increasing the use of 'smart' pump drug libraries by nurses: a continuous quality improvement project.

    Harding, Andrew D

    2012-01-01

    The use of infusion pumps that incorporate "smart" technology (smart pumps) can reduce the risks associated with receiving IV therapies. Smart pump technology incorporates safeguards such as a list of high-alert medications, soft and hard dosage limits, and a drug library that can be tailored to specific patient care areas. Its use can help to improve patient safety and to avoid potentially catastrophic harm associated with medication errors. But when one independent community hospital in Massachusetts switched from older mechanical pumps to smart pumps, it neglected to assign an "owner" to oversee the implementation process. One result was that nurses were using the smart pump library for only 37% of all infusions.To increase pump library usage percentage-thereby reducing the risks associated with infusion and improving patient safety-the hospital undertook a continuous quality improvement project over a four-month period in 2009. With the involvement of direct care nurses, and using quantitative data available from the smart pump software, the nursing quality and pharmacy quality teams identified ways to improve pump and pump library use. A secondary goal was to calculate the hospital's return on investment for the purchase of the smart pumps. Several interventions were developed and, on the first of each month, implemented. By the end of the project, pump library usage had nearly doubled; and the hospital had completely recouped its initial investment. PMID:22186702

  1. Quality Improvement of MARS Code and Establishment of Code Coupling

    International Nuclear Information System (INIS)

    The improvement of MARS code quality and coupling with regulatory auditing code have been accomplished for the establishment of self-reliable technology based regulatory auditing system. The unified auditing system code was realized also by implementing the CANDU specific models and correlations. As a part of the quality assurance activities, the various QA reports were published through the code assessments. The code manuals were updated and published a new manual which describe the new models and correlations. The code coupling methods were verified though the exercise of plant application. The education-training seminar and technology transfer were performed for the code users. The developed MARS-KS is utilized as reliable auditing tool for the resolving the safety issue and other regulatory calculations. The code can be utilized as a base technology for GEN IV reactor applications

  2. Improving the Quality of Published Chemical Names with Nomenclature Software

    2006-11-01

    Full Text Available This work deals with the use of organic systematic nomenclature in scientific literature, its quality, and computerized methods for its improvement. Criteria for classification of systematic names in terms of quality/correctness are discussed and applied to a sample set of several hundred names extracted from the literature. The same structures are named with three popular state-of-the-art nomenclature programs – AutoNom 2000, ChemDraw 10.0, and ACD/Name 9.0. When comparing the results, all nomenclature tools show a significantly better performance than 'average chemists'. One program allows the generation not only of IUPAC names but also of CAS-like index names that are compared with the officially registered names. The scope and limitations of nomenclature software are discussed and a comparison of the programs' actual capabilities is given.

    1998-01-01

    Total Quality Management (TQM) is a new management philosophy and a set of guiding principles that represent the basis of a continuously improving organization. This paper sheds light on the application of TQM concepts for software development. A fieldwork study was conducted on a Lebanese software development firm and its customers to determine the major problems affecting the organization's operation and to assess the level of adoption of TQM concepts. Detailed questionnaires were prepared and handed out to the firm's managers, programmers, and customers. The results of the study indicate many deficiencies in applying TQM concepts, especially in the areas of planning, defining customer requirements, teamwork, relationship with suppliers, and adopting standards and performance measures. One of the major consequences of these deficiencies is considerably increased programming errors and delays in delivery. Recommendations on achieving quality are discussed. PMID:10589453

    The aim of this paper is to improve voltage quality at the terminals of distributed generators (DGs) in an islanded microgrid. To achieve this goal, it is proposed to include separate voltage and current control loops for the fundamental and harmonics frequencies. This way, it is not necessary to consider additional controllers to provide voltage harmonic compensation. The proposed control system can be implemented in a very simple way. The control structure of every single DG unit consists of active and reactive power droop controllers and voltage and current control loops. Simulation results are provided in order to show the effectiveness of the proposed control approach.

  6. Field quality improvements in superconducting magnets for RHIC

    International Nuclear Information System (INIS)

    A number of techniques have been developed-and tested to improve the field quality in the superconducting dipole and quadrupole magnets to be used in the Relativistic Heavy Ion Collider (RHIC). These include adjustment in the coil midplane gap to compensate for the allowed and non-allowed harmonics, inclusion of holes and cutouts in the iron yoke to reduce the so harmonics, and magnetic tuning shims to correct for the residual errors. We compare the measurements with the calculations to test the validity of these concepts

    Matrix Factorization techniques have been successfully applied to raise the quality of suggestions generated by Collaborative Filtering Systems (CFSs). Traditional CFSs based on Matrix Factorization operate on the ratings provided by users and have been recently extended to incorporate demographic aspects such as age and gender. In this paper we propose to merge CFS based on Matrix Factorization and information regarding social friendships in order to provide users with more accurate suggestions and rankings on items of their interest. The proposed approach has been evaluated on a real-life online social network; the experimental results show an improvement against existing CFSs. A detailed comparison with related literature is also present.

  11. Air Quality in Mexico City: Policies Implemented for its Improvement

    Science.gov (United States)

    Paramo, V.

    2007-12-01

    Ozone and suspended particles (PM) are two pollutants in the atmosphere of Mexico City Metropolitan Area (MCMA) that still exceed the recommended Mexican health standards. The other criteria pollutants very seldom exceed their corresponding standards. In 2006, the maximum ozone concentrations were above the health standard (0.11 ppm in 1 hour) during 59 percent of the days for an average of 2.2 hours and 130 points of the Air Quality Index (Índice Metropolitano de la Calidad del Aire - IMECA). In contrast, in 1991, 98 percent of the days exceeded the ozone health standard for an average of 6.6 hours and 200 IMECA points. With regards to PM10, in 2006, 80 percent of the sampled concentrations were below the health standard of 120 µg/m3 in 24 hours. However, the annual health standard of 50 µg/m3 is still exceeded. The air quality management in the MCMA is a difficult task due to several adverse factors. The main one is the large population that increased from nearly 15 million in 1992 to more than 18 million at present. As a result, the urban area grows in the adjoined municipalities of the State of Mexico. The vehicular fleet increases also to almost 4 million and the number of industrial facilities is at present 50,000. Consequently, the fuel consumption is very high. The daily energy consumption is estimated to be 44 million liters of equivalent of gasoline. Despite the fact that the air quality has improved in recent years, the related health standards are still exceeded and therefore it is necessary to continue applying the most cost-effective actions to improve the environment quality. Some actions that have contributed most to the reduction of pollutant emissions are the following: Continuous update of the inspection and maintenance program of the vehicular fleet; substitution of the catalytic converters at the end of their useful life; self-regulation of the diesel fleet; use of alternative fuels; update the No-Driving-Day program; establishment of more stringent emission levels of the gasoline fleet; update the detention of pollutant vehicles program; partial exemption of the inspection and maintenance program for cleaner and or highly efficient vehicles; substitution of 3,000 microbuses, 40,000 taxis and 1,200 buses; commissioning of the first Bus Rapid Transit system; implementation of a program for the emissions reduction for the 300 most polluted industrial facilities; and continuous update of the air quality environmental management programs. To continue improving the air quality in the MCMA, the environmental authorities will continue the implementation of the 2002-2010 Air Quality Improvement Program. In 2007 the Green Program was started, this includes those actions that have proven to be effective reduction of pollutant emissions and incorporates new actions for the reduction of local and global pollutant emissions. The most important of these new actions are: substitution of 9,500 microbuses; renewal of all the taxis fleet; commissioning of 10 Bus Rapid Transit lines; commissioning of Line 12 of the underground system; schedules and routes limitations to the cargo fleet; increase 5 percent the number of non-motorized trips (bicycling and walking); regulation of the private public transport passenger stops; requirement of private schools to provide school transport; regulation of non-occupied taxis in circulation; modifications to the circulation of 350 critical crossing points in the city; adoption of intelligent traffic lights systems; complete substitution of the local government vehicle's fleet; implement the inspection and maintenance of the cargo fleet; introduction of low- sulfur diesel, among other measures.

    2011-11-01

    Full Text Available Fingerprints are the oldest and most widely used form of biometric identification. A fingerprint image may not always be well defined due to elements of noise that corrupts the clarity of the ridge structures or basic information, which is required for recognition. Noise may occur due to variations in skin and impression condition. Thus, image enhancement techniques are often used to reduce the noise and enhance the structure of ridges and valleys for minutiae detection. in this paper, we present a fingerprint image enhancement method which can adaptively improve the clarity of ridge and furrow structures of input fingerprint image based on the frequency and spatial domain filtering , local orientation estimation , local frequency estimation and morphological operation.

    Quality function deployment (QFD) is one of the most effective quality design tools. This study applies QFD technique to improve the quality of the burn unit services in Ghotbedin Hospital in Shiraz, Iran. First, the patients' expectations of burn unit services and their priorities were determined through Delphi method. Thereafter, burn unit service specifications were determined through Delphi method. Further, the relationships between the patients' expectations and service specifications and also the relationships between service specifications were determined through an expert group's opinion. Last, the final importance scores of service specifications were calculated through simple additive weighting method. The findings show that burn unit patients have 40 expectations in six different areas. These expectations are in 16 priority levels. Burn units also have 45 service specifications in six different areas. There are four-level relationships between the patients' expectations and service specifications and four-level relationships between service specifications. The most important burn unit service specifications have been identified in this study. The QFD model developed in the study can be a general guideline for QFD planners and executives. PMID:23884047

    Full Text Available This paper proposed the reduced rating star connected transformer based interline unified power quality conditioner. This work comprises of unified power quality conditioner connected between the two feeders, star connected transformer and LC filter. This hybrid approach significantly improves the performance of UPQC under unbalance source voltage condition. The UPQC adopted to compensate current and voltage-quality problems of sensitive loads and suppressing the load current harmonics under distorted supply conditions. The series converter control strategy is based on the fuzzy-logic controller. The extensive simulation results have carried out in MATLAB/Simulink environment power system blockset toolboxes. From the results it has shown that hybrid interline UPQC achieves superior capability of mitigating the effects of voltage sag/swell and suppressing the load current harmonics, phase current harmonics and neutral current under distorted supply conditions. To validate the results produced by the proposed method, it is compared with the conventional UPQC method and better results obtained from the hybrid approach.

  1. Improving Quality of Service from TCP/IP Performance Degradation

    2011-02-01

    Full Text Available TCP is currently the dominate congestion control protocol for the Internet. However, as the Internet evolves into a high-speed wired-cum-wireless hybrid network, performance degradation problems of TCP have appeared, such as underutilizing high-speed links, regarding wireless loss as congestion signal, and unfairness among flows with different RTTs. In order to improve the quality of service for such highspeed hybrid networks, we propose a router-assisted congestion control protocol called Quick Flow Control Protocol (QFCP. The convergence of many traditional services over IPbased infrastructures drastically increases the amount of IP data traffic to be delivered to user clients, thus raising questions about the management of quality of service in such networks. Quality of service will be of primary importance in order to ensure right operation, and to face the occurrence of congestion conditions, due to bandwidth demandingmultimedia services. in this paper, shows that QFCP can significantly shorten flow completion time, fairly allocate bandwidth resource, and be robust to non-congestion related loss. Also we consider a possible scenarios in which multiple multimedia and control streams are conveyed over the same HAN, and study a possible solution for the implementation of an easily manageable QoS framework, that relies on a QoS router based on open source software.

    Full Text Available Research indicates that many of symptoms attributed to the Sick Building Syndrome in air-conditioned office buildings are a result of considerably reduced negative ions in the internal atmosphere and that replacing the depleted negative ions can improve indoor air quality. This paper describes a method used to develop a formula (DOF-NIL formula for calculating the amount of negative ions to be added to air-conditioned buildings, to improve air quality. The formula enables estimates to be made based on how negative ions in the air are reduced by three main factors namely, Video Display Terminals (VDT; heating, ventilation and air conditioning (HVAC and Building Contents (BC. Calculations for a typical air-conditioned office, are compared with an Air Ion Counter instrument. The results show that the formula, when applied to a typical air-conditioned office, provides an accurate estimate for design purposes. The typical rate of additional negative-ions (ion-generating for a negative ion condition is found to be approximately 12.0 billion ions/hr for at least 4 hour ion-generating.

    Full Text Available With the mounting demand of web applications, a number of issues allied to its quality have came in existence. In the meadow of web applications, it is very thorny to develop high quality web applications. A design pattern is a general repeatable solution to a generally stirring problem in software design. It should be noted that design pattern is not a finished product that can be directly transformed into source code. Rather design pattern is a depiction or template that describes how to find solution of a problem that can be used in many different situations. Past research has shown that design patterns greatly improved the execution speed of a software application. Design pattern are classified as creational design patterns, structural design pattern, behavioral design pattern, etc. MVC design pattern is very productive for architecting interactive software systems and web applications. This design pattern is partition-independent, because it is expressed in terms of an interactive application running in a single address space. We will design and analyze an algorithm by using MVC approach to improve the performance of web based application. The objective of our study will be to reduce one of the major object oriented features i.e. coupling between model and view segments of web based application. The implementation for the same will be done in by using .NET framework.

Cheese is dairy product resulted from fermented milk in which the fermentation process can be done by lactic acid bacteria or fungus. Rhizopus oryzae is able to produce lactic acid, protease and lipase. The ripening process changes the taste and texture. The purpose of this study is ripening to improve the quality of inoculated cheese R. oryzae. In this research the ripening was conducted the concentration variation of temperature (5oC, 10oC, 15oC, and time (7 days, 14 days. The procedure of research consisted of two steps, namely un-ripened cheese preparation followed by ripening cheese preparation. Cheese produced in this study analyzed the value of pH, fat content, protein content, amino acid levels and identification of microbe with ANOVA then followed by DMRT at 5% level of significance. Data results were analyzed with the like’s nonparametric statistical test, followed by Fridman Wilcoxon Signed Rank Test (WSRT at 5% level significance. The results showed that the preferred ripened cheese panelist was at a temperature of 15oC for 14 days. Ripening conditions affect pH, fat content, protein content and do not affect the levels of amino acids that formed ripened cheese. The best quality ripened cheese i.e. at a temperature of 15°C for 14 days, had a pH value of 4.40, the highest protein content of 9.78%, and fat content of 35.02%. The results of identified microbe in un-ripened cheese and ripened cheese include Enterococcus hirae (Enterococcus faecalis, Bacillus subtilis, and Aspergillus sp.

    2012-07-01

    Process and quality improvement techniques have been successfully applied in health care arenas, but efforts to institute these strategies in alcohol and drug treatment are underdeveloped. The Network for the Improvement of Addiction Treatment (NIATx) teaches participating substance abuse treatment agencies to use process improvement strategies to increase client access to, and retention in, treatment. NIATx recommends five principles to promote organizational change: (1) understand and involve the customer, (2) fix key problems, (3) pick a powerful change leader, (4) get ideas from outside the organization, and (5) use rapid cycle testing. Using case studies, supplemented with cross-agency analyses of interview data, this paper profiles participating NIATx treatment agencies that illustrate successful applications of each principle. Results suggest that organizations can successfully integrate and apply the five principles as they develop and test change strategies, improving access and retention in treatment, and agencies' financial status. Upcoming changes requiring increased provision of behavioral health care will result in greater demand for services. Treatment organizations, already struggling to meet demand and client needs, will need strategies that improve the quality of care they provide without significantly increasing costs. The five NIATx principles have potential for helping agencies achieve these goals. PMID:22282129

  7. Implementation of biochemical screening to improve baking quality of barley

    DEFF Research Database (Denmark)

    Vincze, Éva; Dionisio, Giuseppe

    2011-01-01

    Barley (Hordeum vulgare) has the potential to offer considerable human nutritional benefits, especially as supplement to wheat-based breads. Under current commercial baking conditions it is not possible to introduce more that 20% barley flour to the wheat bread without negative impact on the physical chemical properties of the bread products due to the poor baking properties of barley flour. As a consequence, the nutritional advantages of barley are not fully exploited. The inferior leavening and baking properties of barley can, in part, be attributed to the physical properties of the storage proteins. Changing the storage protein composition can lessen this problem. Our working hypothesis was that exploiting the substantial genetic variation within the gene pool for storage proteins could enable improving the baking qualities of barley flour. We characterised forty-nine barley cultivars for variations in storage protein and AA composition. These cultivars were selected based on their higher protein contents (11.8–17.6%). The results obtained indicated that substantial variation not only in the distribution of the hordein polypeptides but also in the relative proportions of the storage proteins affecting the AA compositions as well. Studies based on small scaled baking trials and protein pattern analysis by SDS-PAGE on the high protein barley cultivars suggested differences in baking quality and a correlation between baking quality and the high molecular weight (HMW)-storage proteins. Mass spectrometry (Q-TOF) proved the identity of the HMW proteins and sequencing the digested peptides also revealed possible post translational modifications of the identified HMW hordeins. Our results strongly indicate that the variations in the relative proportions of the storage proteins of barley affect both the amino acid compositions and baking quality.

    Full Text Available Rebecca H LehtoCollege of Nursing, Michigan State University, East Lansing, MI, USAAbstract: Malignant pleural mesothelioma is a relatively rare but aggressive malignancy that is primarily associated with occupational asbestos exposure. While treatment options for mesothelioma have expanded, the disease carries a poor prognosis, with a median of 8 months to 1 year of survival postdiagnosis. This article synthesizes current disease-management practices, including the diagnostic workup, treatment modalities, emerging therapies, and symptom management, and identifies comprehensive nursing strategies that result in the best care based on updated evidence. Multidisciplinary coordination, palliative care initiation, survivorship, and end-of-life care are discussed. Findings may be applied in clinical environments as a resource to help nurses better understand treatment options and care for patients facing malignant pleural mesothelioma. Recommendations for future research are made to move nursing science forward and to improve patient well-being and health-related quality-of-life outcomes for patients and their family members.Keywords: pleural mesothelioma, cancer, symptom management, evidence-based care

    This study evaluated the effectiveness of implementation of common assessment tools, collaborative care plans, and symptom management guidelines for cancer patients as a strategy to improve the quality, coordination, and integration of palliative care service across organizations and health care sectors. A pre-post design to measure the impact on symptom management, caregiver burden and satisfaction with care delivery, and service utilization was used. Two cohorts of eligible patients and caregivers completed Edmonton Symptom Assessment Scales, Caregiver Reaction Assessment and FAMCARE Scales and chart audits were conducted. Administrative data from each participating site were examined for utilization trends. Audits of 53 charts preimplementation and 63 postimplementation showed an increase in documentation of pain from 24.5% to 74.6% (P<0.001) of charts. Administrative data showed a decrease in the percentage of patients with at least one emergency room visit from 94.3% to 84.8% (P<0.001), in the percentage of patients with at least one admission to the acute care hospital (P<0.001), and deaths in acute care 43.1%-35.7% (P=0.133). There was minimal change in the intensity of symptoms (P=0.591), and no change in the burden on the caregiver (P=0.086) or caregiver satisfaction with care (P=0.942). This study showed that implementation of common assessment tools, collaborative care plans, and symptom management guidelines across health sectors can result in some increased documentation of symptoms and efficiencies in care. Future projects should consider imbedding a continuous quality improvement methodology and longer timelines into their projects to improve outcomes. PMID:18358693

    We reviewed the literature for the impact of service delivery initiatives (SDIs) on patients' waiting times within radiology departments. We searched MEDLINE, EMBASE, CINAHL, INSPEC and The Cochrane Library for relevant articles published between 1995 and February, 2013. The Cochrane EPOC risk of bias tool was used to assess the risk of bias on studies that met specified design criteria. Fifty-seven studies met the inclusion criteria. The types of SDI implemented included extended scope practice (ESP, three studies), quality management (12 studies), productivity-enhancing technologies (PETs, 29 studies), multiple interventions (11 studies), outsourcing and pay-for-performance (one study each). The uncontrolled pre- and post-intervention and the post-intervention designs were used in 54 (95%) of the studies. The reporting quality was poor: many of the studies did not test and/or report the statistical significance of their results. The studies were highly heterogeneous, therefore meta-analysis was inappropriate. The following type of SDIs showed promising results: extended scope practice; quality management methodologies including Six Sigma, Lean methodology, and continuous quality improvement; productivity-enhancing technologies including speech recognition reporting, teleradiology and computerised physician order entry systems. We have suggested improved study design and the mapping of the definitions of patient waiting times in radiology to generic timelines as a starting point for moving towards a situation where it becomes less restrictive to compare and/or pool the results of future studies in a meta-analysis.

    Full Text Available The improvement of degraded pastures is important for increasing pasture herbage mass and animal production in southern Chile. While research has normally focused on how animal treading affects soil compaction, no major work has yet been done to define the impact of pasture improvement managements o [...] n soil physical functions, particularly when the initial situation is a degraded pasture. Thus, the aim of this study is to define the short-term effects of different pasture improvement managements on the physical quality and related processes of a volcanic ash soil. Four treatments were defined: two tilled, fertilized and seeded plots (T1 and T2), one non-tilled and non-fertilized plot (T3) and one non-tilled and fertilized plot (T4), all of which were compared to the initial situation of a highly degraded pasture (IS). Undisturbed soil samples were collected (1-10 cm) and the volumetric water content and temperature was continuously monitored at the 10 cm depth. The short-term effects of pasture improvement managements on soil physical quality and related processes differed in relation to the treatment method. As compared to the non-tilled plots, the aggregate destruction after tillage induced an increase in the water holding capacity, but a decrease in the air capacity and pore-continuity values due to grazing. The physical quality assessed by the S-Index reflected a good soil structural quality (S > 0.035). The tilled plots presented a higher S-Index as compared to the non-tilled plots, which is related to a slightly lower mechanical strength and larger water holding capacity. The latter also increased due to tillage and was positively correlated to pasture yields during the first intensive soil drying. Soil temperature differences between treatments were assessed and can be related to the higher water contents in the tilled plots and the presence of broad-leaf species in the non-tilled pastures. Finally, in order to properly understand how the implementation of pasture improvement managements affects the soil physical quality and related processes, long-term studies are required.

    The success of software process improvement (SPI) implementation initiatives depends fundamentally of the strategies adopted to support the execution of such initiatives. Therefore, it is essential to define adequate SPI implementation strategies aiming to facilitate the achievement of organizational business goals and to increase the benefits of process improvements. The objective of this work is to present an approach to support the execution of SPI implementation initiatives. We also describe a methodology applied to capture knowledge related to critical success factors that influence SPI initiatives. This knowledge was used to define effective SPI strategies aiming to increase the success of SPI initiatives coordinated by a specific SPI consultancy organization. This work also presents the functionalities of a set of tools integrated in a process-centered knowledge management environment, named CORE-KM, customized to support the presented approach.

    This paper exploits an energetic initiator realized by integrating Al/Ni multilayer nanofilms with semiconductor bridge (SCB). The as-deposited nanofilms have been characterized with varied analytical techniques. Results show that distinct nanofilms are sputter deposited in a layered geometry and give a heat of reaction equal to 1134 J/g. The firing tests of the initiators were accomplished using capacitor discharge unit. Results show that the initiators possess several excellent characteristics such as fast ignition time, low power consumption, high output energy and so on. Therefore, Al/Ni multilayer nanofilms are suitable heat source for improving the reliability of SCB initiators.

    Development of Putrajaya has changed the character of the natural landform by covering the land with impervious surfaces. Houses, office buildings, commercial place and shopping centres have provided places to live and work. The route between buildings is facilitated and encouraged by a complex network of roads and car parks. However, this change from natural landforms and vegetative cover to impervious surfaces has major effect on stormwater which are water quality (non-point source pollution). This paper describes the effectiveness of the stormwater quality devices to improve water quality at selected Putrajaya for demonstration in order to evaluate low cost storm inlet type devices in the Putrajaya Catchment. Five stormwater quality devices were installed and monitored during the study. The devices include Ultra Drain Guard Recycle model, Ultra Curb Guard Plus, Ultra Grate Guard, Absorbent Tarp and Ultra Passive Skimmer. This paper will provide information on the benefits and costs of these devices, including operations and maintenance requirements. Applicability of these devices in gas stations, small convenience stores, residential and small parking lots in the catchment are possible due to their low cost.

  17. Approaches to improving the nutritional quality of barley seed proteins

    International Nuclear Information System (INIS)

    The poor nutritional quality of barley grain is determined by the low level of lysine in the prolamin storage proteins (hordein). These account for between 35 to 50% of the total grain nitrogen, depending on the nutritional status of the plant. There is a reduced proportion of hordein in mutant high lysine lines but these also have reduced synthesis of storage carbohydrates and hence low yields. Three strategies for improvement are discussed. Increases in the lysine content of hordein may be difficult to achieve because of the presence of complex families of structural genes. It would also be necessary to insert a large number of additional lysine residues. Two more promising approaches are to increase the level of expression of genes coding for lysine-rich globulin storage proteins and to increase the pool of free lysine by selecting mutant lines with relaxed feedback regulation of lysine synthesis.

    Full Text Available Dichotomous choice elicitation technique of contingent valuation method is broadly used in the research fields of environmental resource and recreational activity management. The binary choice type of questions are generally analyzed by using Logit or Probit probability distribution models in which a common analysis procedure is to apply MLE for estimating variable parameters before calculating the respondents’ willingness to pay. In this paper, a MCMC Gibbs sampling Probit model is adopted to maintain the three advantages it has in dealing with heteroscedasticity, high dimension numerical integral and sample size restriction problems. The results revealed that the MCMC model and MLE Probit model are strikingly consistent, which suggests that the former is much simple and reliable estimation method. At the same time, the empirically based existence value estimation of coastal beach quality improvement in Dalian, China is RMB?168 per person.

    International Nuclear Information System (INIS)

    The Water Quality Audit (WQA) is an independent, detailed review and thorough analysis of an operating plant's water technology control systems and operator education (as distinguished from operator training). The need for such an audit and its role in improving the reliability and availability of both nuclear and fossil-fueled power plants is discussed. Instances of how the failure of either system hardware or operational control has caused injection of seawater, acid, caustic, or ion exchange resin into the condensate-feedwater system and steam generator are revealed. The systems to be audited are described, and the stage-wise nature of the audit explained. The potential savings of an audit are outlined and the timing and range of costs of a WQA are given

  1. Improvements of NMR image quality using adaptive nonlinear filter

    International Nuclear Information System (INIS)

    To improve quality of NMR images, a new method of image processing is proposed. Generally, the effective image processing is performed by using features of images. I have found our two features by examining NMR images: 1) noise of NMR image follows Rayleigh distribution, namely salt-and-pepper noise; 2) its standard deviation is easy to calculate. Utilizing these features, I have proposed an adaptive nonlinear filtering method, which is performed by judging the isolation status of pixels using the standard deviation of the noise in NMR image. This method can reduce noise in NMR images without causing significant blurring. Simulations and a human head image using the proposed method are demonstrated and compared with those using conventional filtering method, showing the effectiveness of the new method. (author)

    Full Text Available This research was designed to evaluate the performance of Constructed Wetlands (CW for groundwater quality improvement. In the first phase of this study, performance of CW planted with cattails for Manganese (Mn and Iron (Fe reduction was evaluated at 12, 24 and 48 hours of Hydraulic Retention Time (HRT. Average efficiencies of all tested CW systems were higher than 90 and 75% for Mn and Fe concentration reduction. Subsequently, the efficiency of CW operated at 12 hours of HRT was investigated at different plant harvest intervals. In the second phase of study, Mn and Fe removal efficiencies were 75-100 and 48-99%, respectively. Both Mn and Fe removal efficiencies for the CW system were not different between 4, 6 and 8 weeks of harvest intervals. However, the efficiency obviously increased after the first plant harvest. Average Mn and Fe removal rates of the CWs operated at the tested harvest intervals were 0.068 to 0.092 and 0.383 to 0.432 g/m2/d, respectively. Fe removal rate was not significantly different under the various test conditions. However the highest Mn removal rate was obtained in CWs operated with a harvest interval of 4 weeks. Mn accumulation rates in cattail shoots and roots were 0.04-8.25 and 0.83-23.14 mg/m2/d, respectively. Fe accumulation rates in those were 0.04-164.27 and 249.62-1,701.54 mg/m2/d, respectively. Obviously, cattail underground tissues accumulated both Mn and Fe at higher concentrations than those of the above ground tissue. These results show that CW can improve the quality of groundwater before agricultural irrigation.

    Promulgation of the Clean Water Act (CWA) authorized the United States Environmental Protection Agency (U.S. EPA) to regulate quality standards for surface waters and establish regulations limiting the amounts and types of pollutants entering the nation's waters. U.S. EPA imposed national pretreatment standards on industrial wastes discharged to the collection systems of publicly owned treatment works (POTWs) and promulgated General Pretreatment Regulations in 1978. This study analyzed trace metals data from the National Sewage Sludge Surveys conducted by U.S. EPA and the American Metropolitan Sewage Agencies (AMSA) to evaluate the effect of implementation of the national industrial pretreatment standards on concentrations of trace metals in sludges generated by POTWs in the United States. The data showed that implementation of pretreatment programs has been highly effective in reducing the amount of pollutants that enter POTWs and has resulted in a substantial reduction in the levels of trace metals in the municipal sludges. Concentrations of chromium, lead, and nickel in sludge declined by 78, 73, and 63%, respectively, within a year after promulgation of General Pretreatment Regulations. Resulting from these measures, metal concentrations in the sludges generated by a majority of POTWs in the United States are sufficiently low that the sludges can be classified as biosolids and also meet the U.S. EPA's exceptional quality criteria for trace metals in biosolids. This improvement gives POTWs the option to use their biosolids beneficially through land application. PMID:24645543

  5. Development of high yielding winter rapeseed with improved oil quality

    International Nuclear Information System (INIS)

    In order to secure and increase the consumption of rapeseed oil in the food industry, lower linolenic acid contents are required. Varieties reaching this quality standard must also produce high oil yields for such production to become economic. In a pertinent research programme, first mutation experiments were started in 1968 resulting in an improved fatty acid (f.a.) composition of the seed oil in spring rapeseed genotypes. In the following years selected alleles controlling the expression of low linolenic acid content were transferred from spring type mutants to winter rapeseed via backcrossing. In a further mutation experiment with winter forms, genotypes were selected exhibiting less than 3% linolenic acid content in seed triacylglycerols during tests run over four years. Thus, very low linolenic acid levels were realized also in winter rapeseed varieties. By simultaneously selection for low flucosinolate (gsl) content together with the desired oil quality selection gain for seed yield was reduced considerably. Further backcrossing and continuous selection resulted in high yielding OlO lines. On the other hand S1, recurrent selection proved to be another effective method to accumulate favorable alleles for seed yield in a Ol+base population without changing its favorably low linolenic acid content. Therefore, the transferred mutant alleles do not seem to restrict yield performance. (author). 20 refs, 2 figs, 6 tabs. 20 refs, 2 figs, 6 tabs

  6. Improvement of hygienic quality of white ginseng powders by ?-irradiation

    International Nuclear Information System (INIS)

    For the purpose of improving hygienic quality of white ginseng powders, the comparative effects of ethylene oxide (EO) fumigation and ?-irradiation (5-10 kGy) on the sterilization, physiochemical properties and organoleptic quality were investigated. EO fumigation and ?-irradiation (5-10 kGy) completely eliminated the microorganisms contaminating in white ginseng powder. There was no growth of microorganisms after 7 months storage at 30degC and different relative humidities. In the physiochemical properties, ginseng saponins were considerably resistant to ?-irradiation (less than 10 kGy) and commercial EO fumigation, while sulfur-containing amino acids, reducing sugar and acidity were significantly changed by EO fumigation. EO residues were 570 ppm in the samples taken immediately after deaeration and 170 ppm in the stored samples of 8 days at 30degC, respectively. Ethylene chlorohydrin and ethylene glycol residues as the secondary products of EO were 9,595 ppm immediately after deaeration and 221 ppm in the stored samples of 3 months at 30degC. (author)

  7. Understanding context for quality improvement: artefacts, affordances and socio-material infrastructure.

    2013-09-01

    Against a backdrop of growing concern for patient safety and service quality, modern health-care systems are witnessing a proliferation of improvement initiatives. The impact is often variable, however, and a key theme to emerge from evaluations of these efforts is a recognition of the effects of local context on the success or otherwise of an intervention. However, the 'context' tends to be understood in terms of higher order issues such as structure, culture and leadership. This article explores a dimension of context not typically taken into account in the health-care improvement literature: the infrastructural context. Many quality improvement interventions hinge on the introduction of artefacts to support behavioural change in the workplace. Despite calls from scholars of technology in practice for a greater acknowledgement of the role of such mundane artefacts in supporting the organisation of health-care work, they are rarely considered in these terms in evaluations of improvement efforts. In this article, I argue that understanding the potential generative effects of artefacts for quality improvement purposes requires an understanding of their 'affordances' and how these relate to the socio-material infrastructure into which they are to be introduced, and/or the technologies they are designed to replace. Integrated care pathway implementation is examined to illustrate this position. Drawing on qualitative case studies of integrated care pathway development processes undertaken in the UK National Health Service and ethnographic research on the international care pathway community, I consider the infrastructural reasons behind the challenges of making pathways work in organising health care, and why, contrary to the aspirations of their proponents, they often appear to increase rather than decrease paperwork.

    Full Text Available Abstract Background The evidence base for quality improvement (QI interventions is expanding rapidly. The diversity of the initiatives and the inconsistency in labeling these as QI interventions makes it challenging for researchers, policymakers, and QI practitioners to access the literature systematically and to identify relevant publications. Methods We evaluated search strategies developed for MEDLINE (Ovid and PubMed based on free text words, Medical subject headings (MeSH, QI intervention components, continuous quality improvement (CQI methods, and combinations of the strategies. Three sets of pertinent QI intervention publications were used for validation. Two independent expert reviewers screened publications for relevance. We compared the yield, recall rate, and precision of the search strategies for the identification of QI publications and for a subset of empirical studies on effects of QI interventions. Results The search yields ranged from 2,221 to 216,167 publications. Mean recall rates for reference publications ranged from 5% to 53% for strategies with yields of 50,000 publications or fewer. The 'best case' strategy, a simple text word search with high face validity ('quality' AND 'improv*' AND 'intervention*' identified 44%, 24%, and 62% of influential intervention articles selected by Agency for Healthcare Research and Quality (AHRQ experts, a set of exemplar articles provided by members of the Standards for Quality Improvement Reporting Excellence (SQUIRE group, and a sample from the Cochrane Effective Practice and Organization of Care Group (EPOC register of studies, respectively. We applied the search strategy to a PubMed search for articles published in 10 pertinent journals in a three-year period which retrieved 183 publications. Among these, 67% were deemed relevant to QI by at least one of two independent raters. Forty percent were classified as empirical studies reporting on a QI intervention. Conclusions The presented search terms and operating characteristics can be used to guide the identification of QI intervention publications. Even with extensive iterative development, we achieved only moderate recall rates of reference publications. Consensus development on QI reporting and initiatives to develop QI-relevant MeSH terms are urgently needed.

    Rosenstein, Alan H; O'Daniel, Michelle; White, Susan; Taylor, Ken

    2009-01-01

    Medicare has introduced a number of new payment initiatives that will have a profound effect on hospital reimbursement and quality and safety ratings. The new medical severity diagnosis-related group (MS-DRG) payment system adds a number of new DRG categories to more adequately account for patient severity. The new present-on-admission (POA) initiative is designed to withhold additional reimbursement for selected complications that were not recorded as being POA but that occurred during the course of the hospitalization. The recovery audit contract requires hospitals to repay Medicare for services deemed not clinically necessary based on retrospective chart review. Reimbursement and quality rankings for each of these initiatives are based on the extent and thoroughness of physician chart documentation. Physicians must understand the importance of their role and responsibilities in this process and embrace what needs to be done through appropriate education, coaching, and guidance, which leads to more effective chart documentation.

    Improvement partnerships (IPs) are a model for collaboration among public and private organizations that share interests in improving child health and the quality of health care delivered to children. Their partners typically include state public health and Medicaid agencies, the local chapter of the American Academy of Pediatrics, and an academic health care organization or children's hospital. Most IPs also engage other partners, including a variety of public, private, and professional organizations and individuals. IPs lead and support measurement-based, systems-focused quality improvement (QI) efforts that primarily target primary care practices that care for children. Their projects are most often conducted as learning collaboratives that involve a team from each of 8 to 15 participating practices over 9 to 12 months. The improvement teams typically include a clinician, office manager, clinical staff (nurses or medical assistants), and, for some projects, a parent; the IPs provide the staff and local infrastructure. The projects target clinical topics, chosen because of their importance to public health, local clinicians, and funding agencies, including asthma, attention-deficit/hyperactivity disorder, autism, developmental screening, obesity, mental health, medical home implementation, and several others. Over the past 13 years, 19 states have developed (and 5 are exploring developing) IPs. These organizations share similar aims and methods but differ substantially in leadership, structure, funding, and longevity. Their projects generally engage pediatric and family medicine practices ranging from solo private practices to community health centers to large corporate practices. The practices learn about the project topic and about QI, develop specific improvement strategies and aims that align with the project aims, perform iterative measures to evaluate and guide their improvements, and implement systems and processes to support and sustain those improvements. Since 2008, IPs have offered credit toward Part 4 of Maintenance of Certification for participants in some of their projects. To date, IPs have focused on achieving improvements in care delivery through individual projects. Rigorous measurement and evaluation of their efforts and impact will be essential to understanding, spreading, and sustaining state/regional child health care QI programs. We describe the origins, evolution to date, and hopes for the future of these partnerships and the National Improvement Partnership Network (NIPN), which was established to support existing and nurture new IPs.

  12. Quality assurance of radiotherapy in cancer treatment. Toward improvement of patient safety and quality of care

    International Nuclear Information System (INIS)

    The process of radiotherapy (RT) is complex and involves understanding of the principles of medical physics, radiobiology, radiation safety, dosimetry, radiation treatment planning, simulation and interaction of radiation with other treatment modalities. Each step in the integrated process of RT needs quality control and quality assurance (QA) to prevent errors and to give high confidence that patients will receive the prescribed treatment correctly. Recent advances in RT, including intensity-modulated and image-guided RT, focus on the need for a systematic RTQA program that balances patient safety and quality with available resources. It is necessary to develop more formal error mitigation and process analysis methods, such as failure mode and effect analysis, to focus available QA resources optimally on process components. External audit programs are also effective. The International Atomic Energy Agency has operated both an on-site and off-site postal dosimetry audit to improve practice and to assure the dose from RT equipment. Several countries have adopted a similar approach for national clinical auditing. In addition, clinical trial QA has a significant role in enhancing the quality of care. The Advanced Technology Consortium has pioneered the development of an infrastructure and QA method for advanced technology clinical trials, including credentialing and individual case review. These activities have an impact not only on the treatment received by patients enr on the treatment received by patients enrolled in clinical trials, but also on the quality of treatment administered to all patients treated in each institution, and have been adopted globally; by the USA, Europe and Japan also.

    Reyes–Trujillo E

    2010-10-01

    Full Text Available The growing number of non-linear loads on industrial applications has produced an important impact on the quality of electric power supply due to the increasing of the voltage and current harmonic distortion, and low power factor. In order to solve this, arrangements of capacitors and reactors, known as passive filters have been used. However these filters may produce resonance problems with network impedance, over compensation of reactive power at fundamental frequency, and poor flexibility for dynamic compensation of different frequency harmonic components. As a solution to the problems mentioned above, the active filters have been developed, whose features can be adapted in a dynamic and adjustable way on the requirements of the system to compensate. This paper presents the modelling and simulation results of an active current filter, used to reduce the harmonic distortion and to improve the power factor in an electric industrial system. A six-pulse diode converter has been used as non-linear passive load. During the analysis, it was observed that the total current harmonic distortion (THD was reduced from 16.47% to 0.46%, and the power factor in the distribution bus has improved from 0.5 to 0.95.The waveforms of a three-phase thyristor converter with a DC machine as active non-linear load are shown.

    A new technique to improve the image quality of Ni replicated X-ray mirror is presented. During the manufacturing of XMM Mirror Module between 1994 to 1999, the classical manufacturing process showed its limits. In 1995, the XMM Mirror Module Qualification Model HEW was around 20 arcsec. In 1998, the fifth Flight Model Mirror Module reached 11 arcsec HEW, with a single mirror shell achieving 8 arcsec HEW. The performance of this technology is namely limited by the integration process of the shells. The new technique is based on the following philosophy : Firstly, an accurate measurement of each mirror shell after integration. A dedicated metrology system has been built and allows a precise metrology of the actual surface. Secondly, a modification of the mirror shell and of the support to transfer the stress to a non optical active area. Finally, an ion figuring run to correct the residual shape error of the mirror. The control and evaluation of the process is assured by EUV PSF assessment achieved in the FOCAL X facility developed for XMM. The advantages of this new process are to shape the mirrors in their final hardware configuration and the versality of the process enabling improvement of other kinds of high accuracy mirrors.

    2015-06-01

    The management of pain is one of the greatest clinical challenges for nurses who care for patients during the postoperative period. It can be even more challenging for patients who must manage their own pain after discharge from the health care facility. Research shows that postoperative pain continues to be undermanaged despite decades of education and evidence-based guidelines. Ineffective management of postoperative pain can negatively impact multiple patient outcomes. The purpose of this quality improvement project was to evaluate the effectiveness of a preoperative pain management patient education intervention on improving patients' postoperative pain management outcomes. The project was conducted with patients undergoing same-day laparoscopic cholecystectomy in an outpatient general surgery service at a teaching institution. Patients in the intervention and comparison groups completed the American Pain Society Patient Outcome Questionnaire-Revised during their first postoperative clinic visit 2 weeks after surgery. Results showed that patients who received the preoperative education intervention reported less severe pain during the first 24 hours postoperatively, experienced fewer and less severe pain medication side effects, returned to normal activities sooner, and used more nonpharmacologic pain management methods postoperatively compared with those who did not receive the education.

    Health care and today's medical and technical achievements and approved standards of treatment provide comprehensive quality, safety and traceability of medical procedures respecting the principles of health protection. Continuous education improves the quality of nursing health care and increases the effectiveness of patient care, consequently maintaining and enhancing patient safety. Patient health problems impose the need of appropriate, planned and timely nursing care and treatment. In providing quality nursing care, attention is focused on the patient and his/her needs in order to maintain and increase their safety, satisfaction, independence and recovery or peaceful death, so the health and nursing practices must be systematized, planned and based on knowledge and experience. Health and nursing care of patients at risk of developing acute and chronic wounds or already suffering from some form of this imply preventive measures that are provided through patient education, motivation, monitoring, early recognition of risk factors and causes, and reducing or removing them through the prescribed necessary medical treatment which is safe depending on the patient health status. Except for preventive measures, nursing care of patients who already suffer from some form of acute or chronic wounds is focused on the care and treatment of damaged tissue by providing appropriate and timely diagnosis, timely and proper evaluation of the wound and patient general status, knowledge and understanding of the wide range of local, oral and parenteral therapy and treatment, aiming to increase patient safety by preventing progression of the patient general condition and local wound status and reducing the possibility of developing infection or other complications of the underlying disease. In the overall patient management, through nursing process, medical interventions are implemented and aimed to maintain and optimize health status, prevent complications of existing diseases and conditions, provide appropriate wound treatment, increase satisfaction, reduce pain, increase mobility, reduce and eliminate aggravating factors, and achieve a satisfactory functional and aesthetic outcome. Many scientific researches and knowledge about the pathophysiological processes of wound formation and healing are currently available. Modern achievements can accelerate independence, reduce pain and encourage faster wound healing, thus it is important to continuously develop awareness, knowledge and experience, along with the treatment to achieve, maintain and enhance the quality of health care and patient safety.

    International Nuclear Information System (INIS)

    The use of ionizing radiation as a food preservation technique has been recognized for many years as a means to reduce food losses, improve food safety, and extend shelf life. Furthermore, irradiation can be an effective way of reducing the incidence of food borne disease and treating a variety of potential problems in food supplies. The treatment of food with ionizing radiation is one of the most thoroughly researched techniques available to the food processing industry. In view of the afore mentioned the objective of this study were to study the effect of irradiation time and dose on Ras cheese quality, investigate the effect of irradiation after ripening on cheese quality and possibility of prolonging the shelf-life of Ras cheese, study the effect of irradiation dose on Kareish cheese quality and its shelf- life and to monitor the chemical, microbiological and sensory changes during ripening and storage of Ras and Kareish cheeses .The results of this study will be presented in three parts: Part I: Effect of irradiation dose and time on some properties of Ras cheese:Part II: Effect of irradiation on some properties during storage of ripened Ras cheese.Part III: Effect of irradiation on the quality and shelf-life of Kareish cheese: It could be concluded that irradiation caused a significant reduction of cheese ripening indices, and count of total viable,proteolytic, lipolytic bacteria and mould and yeast. Using irradiation doses of 3 and 4 kGy were able to stop the rses of 3 and 4 kGy were able to stop the ripening factors and these safety dose were used to prevent the ripened Ras cheese irradiation of ripened Ras cheese has been prolonged the shelf-life of Ras cheese to about 32 months compared with control cheese, which showed only 18 months. The obtained results revealed that the best irradiation treatment was at the end of ripening period. Also safety irradiation of Kareish cheese has been prolonged the shelf-life of Kareish cheese to about 54 days compared with 12 days only control cheese.

    To present the results of a systematic literature search aimed at determining to what extent the radiation dose can be reduced with iterative reconstruction (IR) for cardiopulmonary and body imaging with computed tomography (CT) in the clinical setting and what the effects on image quality are with IR versus filtered back-projection (FBP) and to provide recommendations for future research on IR. We searched Medline and Embase from January 2006 to January 2012 and included original research papers concerning IR for CT. The systematic search yielded 380 articles. Forty-nine relevant studies were included. These studies concerned: the chest(n = 26), abdomen(n = 16), both chest and abdomen(n = 1), head(n = 4), spine(n = 1), and no specific area (n = 1). IR reduced noise and artefacts, and it improved subjective and objective image quality compared to FBP at the same dose. Conversely, low-dose IR and normal-dose FBP showed similar noise, artefacts, and subjective and objective image quality. Reported dose reductions ranged from 23 to 76 % compared to locally used default FBP settings. However, IR has not yet been investigated for ultra-low-dose acquisitions with clinical diagnosis and accuracy as endpoints. Benefits of IR include improved subjective and objective image quality as well as radiation dose reduction while preserving image quality. Future studies need to address the value of IR in ultra-low-dose CT with clinically relevant endpoints. (orig.)

  2. Improving the quality of pork and pork products (EU-project)

    DEFF Research Database (Denmark)

    Christensen, M.; Grunert, Klaus G.

    Quality of pork has become a complex and dynamic theme involving the total pork chain from fork-to-farm-to-fork with a multitude of interacting aspects related to people's demands as consumers, and the demands of people as citizens and producers for economic and environmental sustainability. The European Unions self-sufficiency and leading position in the global market for pork and pork products is challenged by a number of non-European countries. Therefore, there is a need for developing innovative, integrated, and sustainable food production chains of high quality pork products matching consumer demands. A large EU-project (Q-PorkChains) funded by EU 6th framework programme was initiated in January 2007. The aim of Q-PorkChains is to improve the quality of pork and its products for the consumer and to develop innovative, integrated and sustainable food production chains with low environmental impact. Q-PorkChains is composed of six research modules (consumer and citizen demands, pig production, product development, pork chain management, molecular quality control and knowledge synthesis) and two horizontal modules focusing on implementation of obtained knowledge in pilot and demonstration chains and dissemination to stakeholders at all levels. The project comprises 51 partners from 15 European and 4 non-European countries (China South Africa, Brazil and USA).

  3. Improving convergence and solution quality of Hopfield-type neural networks with augmented Lagrange multipliers.

    Science.gov (United States)

    Li, S Z

    1996-01-01

    Hopfield-type networks convert a combinatorial optimization to a constrained real optimization and solve the latter using the penalty method. There is a dilemma with such networks: when tuned to produce good-quality solutions, they can fail to converge to valid solutions; and when tuned to converge, they tend to give low-quality solutions. This paper proposes a new method, called the augmented Lagrange-Hopfield (ALH) method, to improve Hopfield-type neural networks in both the convergence and the solution quality in solving combinatorial optimization. It uses the augmented Lagrange method, which combines both the Lagrange and the penalty methods, to effectively solve the dilemma. Experimental results on the travelling salesman problem (TSP) show superiority of the ALH method over the existing Hopfield-type neural networks in the convergence and solution quality. For the ten-city TSPs, ALH finds the known optimal tour with 100% success rate, as the result of 1000 runs with different random initializations. For larger size problems, it also finds remarkably better solutions than the compared methods while always converging to valid tours. PMID:18263545

    2011-01-01

    According to saliency of permanent magnet synchronous motor (PMSM), the information of rotor position is implied in performance of stator inductances due to the magnetic saturation effect. Researches focused on the initial rotor position estimation of PMSM by injecting modulated pulse voltage vectors. The relationship between the inductance variations and voltage vector positions was studied. The inductance variation effect on estimation accuracy was studied as well. An improved five-pulses injection method was proposed, to improve the estimation accuracy by choosing optimaized voltage vectors. The experimental results show that the proposed method estimates the initial rotor position reliably and efficently. The method is also simple and can achieve satisfied estimation accuracy.

    Bie Bogh, SØren; Hollnagel, Erik

    Objectives: To examine the development in process quality related to stroke, heart failure and ulcer (bleeding and perforated) between accredited and non-accredited hospitals. Method: All Danish hospitals which treated patients with stroke or heart failure during 2004-2008 or treated patients with bleeding or perforated ulcer during 2006-2008 were included. The hospitals were categorized in two groups, non-accredited hospitals (i.e., hospitals not participating in an accreditation program) and hospitals accredited either by Joint Commission International or Health Quality Service. Individual-level processes of care data was obtained from national population-based registries. The accredited and non-accredited hospitals were compared using 20 processes of care indicators reflecting hospital compliance with national clinical guidelines. The 20 indicators included seven indicators for stroke, seven indicators for heart failure, three indicators for bleeding ulcer and three indicators for perforated ulcer. The primary outcome was the composite fulfilment of process indicators. The secondary outcome was all-or-none, defined as the proportion of patients receiving 100 % of the recommended processes of care. Two-sided t tests were used for statistical analysis with p < 0.05 as a significance level. Results: A total of 70120 patients from 24 hospitals were included. Analysis of the composite fulfilment of process indicators showed no differences at baseline between accredited and non-accredited hospitals for neither stroke (P = 0.55), heart failure (P=0.88), bleeding ulcer (P=0.67) and perforated ulcer (P =0.16). Non-accredited hospitals performed better in the study period regarding stroke (P<0.01) (table 1), whereas no clear differences were found for heart failure, bleeding ulcer or perforated ulcer. Non-accredited hospitals had statically larger improvement in all-or-none indicator related to stroke compared with accredited hospitals (P = 0.04). No difference in heart failure, bleeding ulcer or perforated ulcer wasfound. Conclusions: This study does not support the hypothesis that accredited hospitals provide better process of care quality.

    Full Text Available Quality has been one of the most important factors in judging any product. Quality means “a degree or grade of excellence or worth”. Quality is a term that is usually described using adjectives. Quality has several attributes to it, some of which can be quantified using metrics. These attributes such as usability, portability, security, performance, reliability etc have different importance in different projects. Different software quality assurance methods & practices have been used in different software projects to attain the true value. Quality is an attribute which is a distinct feature and it differs with people’s perception. Achieving high software quality involves measurement of software metrics and optimization based on estimated values. As the software systems grow larger, complexity ofdesign and implementation increases, and this in turn is more prone to defects and hence directly affect the quality of the systems. However, in any software project, high quality is always desirable, and many projects have specific quality requirements. Achieving high software quality involves measurement of software metrics and optimization based on estimated values. Developing high quality software is governed by factors such as people, process, technology and cost. This paper attempts to present a novel approach towards achieving high software quality in various kinds of projects under given constraints.

    2012-05-01

    Benchmarking, a management approach for implementing best practices at best cost, is a recent concept in the healthcare system. The objectives of this paper are to better understand the concept and its evolution in the healthcare sector, to propose an operational definition, and to describe some French and international experiences of benchmarking in the healthcare sector. To this end, we reviewed the literature on this approach's emergence in the industrial sector, its evolution, its fields of application and examples of how it has been used in the healthcare sector. Benchmarking is often thought to consist simply of comparing indicators and is not perceived in its entirety, that is, as a tool based on voluntary and active collaboration among several organizations to create a spirit of competition and to apply best practices. The key feature of benchmarking is its integration within a comprehensive and participatory policy of continuous quality improvement (CQI). Conditions for successful benchmarking focus essentially on careful preparation of the process, monitoring of the relevant indicators, staff involvement and inter-organizational visits. Compared to methods previously implemented in France (CQI and collaborative projects), benchmarking has specific features that set it apart as a healthcare innovation. This is especially true for healthcare or medical-social organizations, as the principle of inter-organizational visiting is not part of their culture. Thus, this approach will need to be assessed for feasibility and acceptability before it is more widely promoted. PMID:23634166

    Whole blood from the heart-lung (bypass) machine may be processed through a cell salvaging device (i.e., cell saver [CS]) and subsequently administered to the patient during cardiac surgery. It was determined at our institution that CS volume was being discarded. A multidisciplinary team consisting of anesthesiologists, perfusionists, intensive care physicians, quality improvement (QI) professionals, and bedside nurses met to determine the challenges surrounding autologous blood delivery in its entirety. A review of cardiac surgery patients' charts (n = 21) was conducted for analysis of CS waste. After identification of practices that were leading to CS waste, interventions were designed and implemented. Fishbone diagram, key driver diagram, Plan-Do-Study-Act (PDSA) cycles, and data collection forms were used throughout this QI process to track and guide progress regarding CS waste. Of patients under 6 kg (n = 5), 80% had wasted CS blood before interventions, whereas those patients larger than 36 kg (n = 8) had 25% wasted CS before interventions. Seventy-five percent of patients under 6 kg who had wasted CS blood received packed red blood cell transfusions in the cardiothoracic intensive care unit within 24 hours of their operation. After data collection and didactic education sessions (PDSA Cycle I), CS blood volume waste was reduced to 5% in all patients. Identification and analysis of the root cause followed by implementation of education, training, and management of change (PDSA Cycle II) resulted in successful use of 100% of all CS blood volume.

    2014-03-01

    Obstructive sleep apnea (OSA) is more common in surgical candidates than in the general population and may increase susceptibility to perioperative complications that range from transient desaturation to catastrophic injuries. Understanding the potential impact of OSA on patients' surgical risk profile is of particular interest to otolaryngologists, who routinely perform airway procedures-including surgical procedures for treatment of OSA. Whereas the effects of OSA on long-term health outcomes are well documented, the relationship between OSA and surgical risk is not collinear, and clear consensus on the nature of the association is lacking. Better guidelines for optimization of pain control, perioperative monitoring, and surgical decision making are potential areas for quality improvement efforts. Many interventions have been suggested to mitigate the risk of adverse events in surgical patients with OSA, but wide variations in clinical practice remain. We review the current literature, emphasizing recent progress in understanding the complex pathophysiologic interactions noted in OSA patients undergoing surgery and outlining potential strategies to decrease perioperative risks.

The methods currently available for measuring surfaces allow a large number of heights on a surface to be measured with high lateral and vertical resolution. However, measured data often contain outliers, which take the form of sharp peaks on the surface (Dirac type) and are particularly common in optical measuring methods. By nature, these peaks cannot belong to a ‘real’ surface; thus, an outlier filtering step is necessary and should be the initial preparation step for the measured data prior to any further analysis. The measurement artefacts can strongly influence the topographic characterization parameters and adversely influence quality control efforts as well as functional analyses for discrimination and correlation of the surfaces. The proposed method makes the filtering of such outliers easier and more effective with criteria linked to the standard deviation (Peirce method) and associated with a modal form-filtering method that is independent of the presence of these peaks. The filter is then applied to the surface at different scales; thus, the method is scale sensitive and improves the filter efficiency. This new method is applied to surface data that were measured by optical means from different surfaces. The surfaces were measured with a 3D-measuring laser microscope and laser scanning confocal microscopy. The results of testing these examples will determine the extent to which this method can improve the quality of measured data and thus influence the results of further analyses. (paper)

    2012-01-01

    Full Text Available Introduction. Quality is a part of curricula in medical schools worldwide. It has a special position in family medicine, because it follows specific rules that are adapted to this discipline. Because of its specificities, teaching quality is even more important to become a part of specialist training curricula. Objective. Our aim was to describe quality improvement in family medicine specialist training curriculum in Slovenia and its practical implications and experiences. Methods. The paper describes the family medicine specialist training curriculum also including the topic on the ways quality improvement. Assignments and research protocols are used to enhance the usage of quality methods in everyday practice. An example of such a research protocol, developed by one of the trainees, is used to illustrate the process. Trainees’ evaluations of the quality improvement curriculum are analyzed. Results. In the quality improvement project, 199 patients with arterial hypertension younger than 80 years were included. At the first measurement only 21 patients (10.6% had their blood pressure within the recommended level. Six months after the quality improvement intervention 77 patients (38.9% had controlled their blood pressure, a statistically significant improvement (p<0.001. Conclusion. Teaching quality in family medicine must be a generic part of specialist training curriculum. The use of specific assignments can underpin the necessity to use methods that follow the principles of modern education. The result of teaching process can be even measured in actual improvement in the quality of care.

  13. Project Specific Quality Assurance Plan Project (QAPP) W-211 Initial Tank Retrieval Systems (ITRS)

    International Nuclear Information System (INIS)

    This Quality Assurance Program Plan (QAPP) provides information on how the Project Hanford Quality Assurance Program is implemented by CH2M HILL Hanford Group Inc (CHG) for managing the Initial Tank Retrieval Systems (ITRS), Project W-211. This QAPP is responsive to the CHG Quality Assurance Program Description (QAPD) (LMH-MP-599) which provides direction for compliance to 10 CFR 830 120, ''Nuclear Safety Management, Quality Assurance Requirements'', and DOE Order 5700 6C, ''Quality Assurance'' Project W-211 modifies existing facilities and provides systems for retrieval of radioactive wastes from selected double-shell tanks (DST). The contents of these tanks are a combination of supernatant liquids and settled solids. To retrieve waste from the tanks, it is first necessary to mix the liquid and solids prior to transferring the slurry to alternative storage or treatment facilities. The ITRS will provide systems to mobilize the settled solids and transfer the wastes out of the tanks. In so doing, ITRS provides feed for future processing plants, allows for consolidation of tank solids to manage space within existing DST storage capacity, and supports continued safe storage of tank waste. This project includes the design, procurement, construction, startup and turnover of these retrieval systems This QAPP identifies organizational structures and responsibilities. Implementing procedures used by CHG project management can be found in the CHG Quality Assurance Program (CHG QAP) Implementation Matrix located in HNF-IP-0842, Volume XI, Attachment Proposed verification and inspection activities for critical items within the scope of project W-211 are identified in Attachment 1 W-211. Project participants will identify the implementing procedures used by their organization within their QAF'Ps. This project specific QAPP is used to identify requirements in addition to the QAPD and provide, by reference, additional information to other project documents

    Introduction Quality improvement (QI) activities are an important part of residency training. National studies are needed to inform best practices in QI training and experience for residents. The impact of the Institutional Review Board (IRB) process on such studies is not well described. Methods This observational study looked at time, length, comfort level, and overall quality of experience for 42 residency training programs in obtaining approval or exemption for a nationally based educational QI study. Results For the 42 programs in the study, the time period to IRB approval/exemption was highly variable, ranging from less than 1 week to 56.5 weeks; mean and median time was approximately 18 weeks (SD, 10.8). Greater reported comfort with the IRB process was associated with less time to obtain approval (r??=???.50; P?quality of experience with the IRB process was also associated with less time to obtain IRB approval (r??=???.60; P?initiating QI studies shows considerable variance that is not explained by attributes of the projects. New strategies are needed to assist and expedite IRB processes for QI research in educational settings and reduce interinstitutional variability and increase comfort level among educators with the IRB process.

    Monitoring the quality of supplementary immunization activities (SIAs) is a key tool for polio eradication. Regular monitoring data, however, are often unreliable, showing high coverage levels in virtually all areas, including those with ongoing virus circulation. To address this challenge, lot quality assurance sampling (LQAS) was introduced in 2009 as an additional tool to monitor SIA quality. Now used in 8 countries, LQAS provides a number of programmatic benefits: identifying areas of weak coverage quality with statistical reliability, differentiating areas of varying coverage with greater precision, and allowing for trend analysis of campaign quality. LQAS also accommodates changes to survey format, interpretation thresholds, evaluations of sample size, and data collection through mobile phones to improve timeliness of reporting and allow for visualization of campaign quality. LQAS becomes increasingly important to address remaining gaps in SIA quality and help focus resources on high-risk areas to prevent the continued transmission of wild poliovirus. PMID:25316852

  17. Improving quality and the assurance of quality in the design and construction of nuclear power plants: a report to Congress

    International Nuclear Information System (INIS)

    A study was conducted of existing and alternative programs for improving quality and the assurance of quality in the design and construction of commercial nuclear power plants. A primary focus of the study was to determine the underlying causes of major quality-related problems in the construction of some nuclear power plants and the untimely detection and correction of these problems. The study concluded that the root cause for major quality-related problems was the failure or inability of some utility managements to effectively implement a management system that ensured adequate control over all aspects of the project. These management shortcoming arose in part from inexperience on the part of some project teams in the construction of nuclear power plants. NRC's past licensing and inspection practices did not adequately screen construction permit applicants for overall capability to manage or provide effective management oversight over the construction project. The study recommends a number of improvements in industry and NRC programs. For industry, the study recommends self-imposed rising standards of excellence, treatment of quality assurance as a management tool, not a substitute for management, improved trend analysis and identification of root causes of quality problems, and a program of comprehensive third party audits of present and future construction projects. To improve NRC programs, the study recommends a heavier emphasis on team inspections and resident inspectors, an enhanced review of new applicant's capabilities to construct commercial nuclear power plants, more attention to management issues, improved diagnostic and trending capabilities, improved quality and quality assurance for operating reactors, and development of guidance to facilitate the prioritization of quality assurance measures commensurate with the importance of plant structures, systems, and components to the achievement of safety

    Full Text Available As a result of lack of conformity of the outer diameter of the filling piston of plastic syringe to the specifications set out in the design map and the increased demand for its  products from the Medical syringes factory – Babylon. The research conducts the necessary investigations and  analysis of the production process as most of the units rejected by fact that the outer diameter of the filling piston is smaller than the minimum specification and units returned to work  due to the fact that  the outer diameter larger than the upper limit of the specification.13The research aims firstly to examine the outer diameter of the filling piston through the use of the control chart of the variables represented by the average , and its impact on the production process capability because the increase in diameter specification leads to an increase in the pressure imposed on the lining of the cylinder, causing difficulty in piston movement and a decrease in diameter specification which leads to loose the process capability to prevent leakage of fluid, causing air to enter as well as to speed the movement of the piston, which negatively affects human life in both cases. Secondly, study the possibility of improving the production process capability by using advanced levels of the sigma.The results showed that the production process in the case of a disciplined and follows a normal distribution, the pointer of  the production process capability is equal to (0.55 and the factory works within the level of Sigma equal to (1.65. The proportion of a damaged product is (15.8 % and rework (0.99 %.In order to  reduce the proportion of damaged product, this paper introduces a quality plan depending on ( ±0.025 as tolerance limits instead of ( ±0.05 to increase sigma level by 202%.

  19. The urgent need for quality improvement in Russia.

    Induced abortion became accepted as a legal method of family planning after the October Revolution of 1917 from which terminations were performed in state hospitals free of charge upon a woman's request. The procedure was made legal in response to then newly voiced egalitarian ideals and the increasing involvement of women in the labor market, as well as because of the rapidly deteriorating situation and post-Revolution period of famine. Administrators fully expected to reduce the incidence of abortion once living conditions improved. Little was done at the time to develop contraceptives. Stalin, however, in the 1920s and 1930s, lamented a falling birth rate in the face of manpower needed for labor and the military; abortion and contraceptives were banned, leading to post-abortion complications without really stimulating the birth rate. Abortion was relegalized in 1956, but the right to contraception was never fully restored. Seven million induced abortions were officially registered to have taken place in each of the last ten years in the former Soviet Union. A woman typically undergoes one abortion per year, or approximately twenty abortions during the childbearing period of her life. Lacking knowledge about contraception, contraceptives, and what many Western countries regard to be women's reproductive health rights, most Russian women, however, freely tolerate frequent repeated abortion as a normal method of fertility regulation. Lack of access to contraceptives along with the lack of domestic contraceptive method production facilities and lack of hard currency to secure quality supplies from abroad are contributing factors to this ongoing trend. Gynecologists also receive lucrative fees for illegal abortions and are unlikely to promote change. Plans to open twelve family planning centers in Moscow have been hampered by the inertia of bureaucracy, the lack of financial means, the lack of trained personnel, and people's suspicion of government bodies. Much needs to be done in Russia about family planning, including involving men in matters of sexual behavior and birth control. PMID:12318912

    Deng, Di; Lin, Weider; Law, Frieda

    2015-06-01

    This multicenter study evaluated the quality of life (QOL) of patients with advanced cancer and assessed the improvement in patients' QOL by hospice service program, using McGill Quality of Life Questionnaire-Hong Kong version (MQOL-HK) questionnaire in China's 32 hospice centers from March to June, 2012. Among 640 recruited cases, data of 630 patients were analyzed. Differences in patients' pre- and posthospice QOL were evaluated. Compared to prehospice results, patients' QOL scores improved significantly in physical, psychological, existential, and support domains after 3 weeks of hospice services. Some items were not thus classified primarily due to cross-cultural adaptation. The MQOL-HK questionnaire could effectively measure QOL in Chinese hospice patients and their QOL could be improved by hospice services. Psychological, existential, and support services should be emphasized during patients' initial 3 weeks of hospice admission. PMID:24526763

    2003-01-01

    This paper proposes a traffic shaping algorithm based on neural networks, which adapts to a network over which streaming video is being transmitted. The purpose of this intelligent shaper is to eradicate all traffic congestion and improve the end-user's video quality. It possesses the capability to predict, to a very high level of accuracy, a state of congestion based upon the training data collected about the network behaviour. Initially, the current traffic shaping technologies are discussed and later a simulation in a controlled environment is illustrated to exhibit the effects of this intelligent traffic-shaping algorithm on the underlying network real time packet traffic and the eradication of unwanted abruption in the streaming video qualiy. This paper concluded from the end results of the simulation that neural networks are a very superior means of modeling real-time traffic and that it can be applied as an appropriate solution to network congestion.

    About 1.6 million new cancer cases are diagnosed in the United States annually and, by 2030, this figure is estimated to reach 2.3 million (Bylander, 2013). These numbers are daunting and require new approaches for planning and implementing services throughout the continuum of care (Ferrell, McCabe, & Levit, 2013). For more than two decades, the U.S. healthcare system has been in flux as leaders in business, health, education, technology, and government grapple with the growth, complexity, and scale of change required to improve care delivery. Reform and change initiatives are important in the quest to optimize quality and outcomes for individuals, teams, populations, and organizations. Oncology nurses are well suited to be able to affect change and find opportunities to guide organizational changes (Day et al., 2014). ?. PMID:26000575

  6. Survey of Image quality and Patient Dose in Simple Radiographic Examinations in Madagascar: Initial results

    International Nuclear Information System (INIS)

    The purpose of this study is to survey image quality and patient doses in radiographic examinations and to perform comparisons with the international Diagnostic Reference Levels (DRLs). This study is part of an International Atomic energy Agency (IAEA) project (RAF/9/033) and one public hospital and two private hospitals were selected. The rate of unsatisfactory images and image qualities grade were noted, and causes for poor image quality were investigated. Doses delivered to patients were determined in terms of entrance skin dose (ESD) based on X-ray tube output measurements and X-ray exposure parameters. Corrective actions were taken mainly in termes of field size and exposure parameters adjustment and data were recollected. The image quality was improved up to 35% in these three hospitals. Results showed that there is a large variation of patient doses for common examination in three hospitals. Patient dose reductions ranging from 2 to 82% were achieved. Comparisons of dose levels with IAEA Guidance Levels (GLs) after implementing corrective actions showed that patient doses are lower than reference levels except for chest exam in two hospitals and skull in one hospital. Actions are under way to extend measurements to a national level in order to estabilish national GLs

    To reduce the frequency of electrically initiated, 20mm munition hangfires (delayed ignitions), a joint Army/NASA investigation was conducted to recommend quality evaluation improvements for acceptance of both primers and gun propellant. This effort focused only on evaluating ignition and combustion performance as potential causes of hangfires: poor electrical initiation of the primer, low output performance of the primer, low ignition sensitivity of the gun propellant, and the effects of cold temperature. The goal was to determine the "best" of the Army and NASA test methods to assess the functional performance of primers and gun propellants. The approach was to evaluate the performance of both high-quality and deliberately defective primers to challenge the sensitivity of test methods. In addition, the ignition sensitivity of different manufacturing batches of gun propellants was evaluated. The results of the investigation revealed that improvements can be made in functional evaluations that can assist in identifying and reducing ignition and performance variations. The "best" functional evaluation of primers and propellant is achieved through a combination of both Army and NASA test methods. Incorporating the recommendations offered in this report may provide for considerable savings in reducing the number of cartridge firings, while significantly lowering the rejection rate of primer, propellant and cartridge lots. The most probable causes for ignition and combustion-related hangfires were the lack of calcium silicide in the primer mix, a low output performance of primers, and finally, poor ignition sensitivity of gun propellant. Cold temperatures further reduce propellant ignition sensitivity, as well as reducing burn rate and chamber pressures.

    Full Text Available This study investigated companies publicly listed in Taiwan from 2002 to 2010 to examine whether independent directors improve the quality of earnings and analyzed whether the control rights of a controlling shareholder mitigate the impact of independent directors on earnings quality. Empirical results showed that independent directors can improve the quality of earnings, and those hired because of mandatory appointments had a greater positive effect on earnings quality compared to directors who were voluntarily hired. In addition, we also found that the controlling share held by a controlling shareholder reduces the benefit of independent directors on earnings quality.

    Full Text Available In recent years there have been significant improvements in outcome of rectal cancer treatment. Both new surgical techniques as well as effective neoadjuvant treatment regimens have contributed to these improvements. It is key to spread these advances towards every rectal cancer patient and to make sure that not only patients who are treated within the framework of clinical trials may benefit from these advancements. Throughout Europe there have been interesting quality programs that have proved to facilitate the spread of up to date knowledge and skills among medical professionals resulting in improved treatment outcome. Nevertheless, between European countries remain differences in outcome and treatment schedules that cannot be easily explained. The European CanCer Organisation (ECCO has recognised these importances's and created the 'European Registration of Cancer Care' (EURECCA framework to develop a European colorectal audit structure. EURECCA will advance future treatment improvements and spread these to all European cancer patients. It provides opportunities to treat elderly and comorbid patients evidence based while it offers an unique insight in social-economical healthcare matters. As such, ECCO has established the basis for a strong, multidisciplinary audit structure with the commitment to improve cancer care for every European cancer patient.

    We report the improvement of the hardness and modulus properties in a silsesquioxane-based soft replica mold by adding thermal initiator, without deteriorating the UV transmittance at the wavelength of 365 nm. It is found that thermal initiator used for this work contributes to improving the hardness and modulus values up to 0.175 and 3.585 GPa, while the UV transmittance value is still above 75%. The optimized soft replica mold built on a flexible plastic substrate allows submicron-scale patterns to be transferred onto a rigid Si substrate by means of UV-NIL process. Consequently, we demonstrate that the developed soft replica mold can be a suitable replacement for typical hard molds, promising further use in mold-based nanolithography for the fabrication of high-resolution nanopatterns over large areas.

    This position paper recommends a set of standards for quality assessment of continuing professional development (CPD) for medicines research and development (R&D). We have developed these standards to help us achieve the education and training goals of the Innovative Medicines Initiative (IMI; www.imi.europa.eu/), which is developing courses to address the skills gaps in European medicines R&D. The IMI shared standard for course quality will enable professionals in medicines R&D to create a personalized portfolio of education and training that best suits their needs. Individuals already working in the pharmaceutical industry will be able to select modules for study on an as-needs basis, which may be combined to gain a qualification that is recognized throughout Europe. By seeking input from the medicines R&D community, especially professional bodies involved in the career development of biomedical scientists, we hope to initiate the creation of a mutually recognized framework for lifelong learning in medicines R&D. The shared standards call for defined and transparent admission criteria, a predefined set of teaching objectives leading to defined learning outcomes, assessment of the students' achievement, a system for collecting, assessing and addressing feedback, and provision of appropriate and updated reference material. This framework will make it easier for professionals to develop the skills required by industry, and easier for employers to recognize professionals with appropriate skills. It will obviate some of the need for retraining personnel who have already developed appropriate skills in a different setting, thereby saving the industry additional effort. Fulfilment of quality standards by course providers will be made transparent within the IMI's catalogue of courses, on-course (www.on-course.eu), which will be made publicly available during 2012.

  17. Suggestion for improvement of PET quality control tests in Brazil

    International Nuclear Information System (INIS)

    Nowadays nuclear medicine has a considerable importance among the other medical specialties. This medical specialty utilizes high-tech equipment for imaging in the diagnosis, obtaining information on the clinical functionality of organs and systems of the human body through the use of radioisotopes . In view of the importance of guaranteeing the image quality in SPECT and PET systems, enabling patients not repeat exams due to lack of quality control of equipment used in nuclear medicine, this paper aims to present a possible suggestion to update the quality control tests needed for quality assurance of nuclear medicine services. They were considered the requirements of the National Commission of Nuclear Energy (CNEN) and the National Health Surveillance Agency (ANVISA) in Brazil. The minimum requirements to be defined for inclusion of quality control tests on PET in the standard CNEN are extremely important because they will guide the evaluation of PET systems, determining the quality control tests to be performed. And those tests for PET will be a regulatory requirement by the CNEN and ANVISA. As the National Health Surveillance Agency has already publication of RDC 38 with recommendations for services of nuclear medicine. This study will continue with evaluation of PET systems and presenting the tests of quality control with additional objects and simulators to ensure safety in PET systems have not standardized in nuclear medicine services in Brazil.

    The activation of oxygenated hemoglobin (oxy-Hb) has been shown to be lacking in the prefrontal cortex (PFC) of patients with late-onset depression (LOD), in verbal fluency task (VFT)-related near-infrared spectroscopy (NIRS). In our previous studies, we have emphasized the connection between the lack of activation in the frontopolar cortex and social functioning disorder in patients with LOD. In this study, we investigated whether the responsiveness to medical treatment of untreated patients with LOD, particularly social functioning improvements, could be predicted by NIRS findings at the initial examination. The subjects were 29 patients with LOD who were diagnosed with major depression at 65 years or older at the initial examination (mean age ± standard deviation, 72.4 ± 5.71 years). We measured the changes in hemoglobin concentration in the prefrontal and temporal cortex regions during a VFT by using 52-channel NIRS. In addition, depression status and social functioning were evaluated with the Hamilton Depression Rating Scale and the Social Adaptation Self-evaluation Scale, respectively, at the initial examination and 8 weeks after the treatment. A negative correlation was found between the NIRS activation in the right ventrolateral PFC region before treatment and the improvement in social functioning. These results suggested that the social functioning improvements were greater in LOD with initially lower NIRS activation in the right ventrolateral PFC region. NIRS is a simple technique that can be used before treatment to evaluate the social functioning levels of patients with LOD, and predict social functioning improvement after treatment. PMID:25659188

    The Savannah River National Laboratory implemented a constructed wetland treatment system (CWTS) in 2000 to treat industrial discharge and stormwater from the Laboratory area. The industrial discharge volume is 3,030 m3 per day with elevated toxicity and metals (copper, zinc and mercury). The CWTS was identified as the best treatment option based on performance, capital and continuing cost, and schedule. A key factor for this natural system approach was the long-term binding capacity of heavy metals (especially copper, lead, and zinc) in the organic matter and sediments. The design required that the wetland treat the average daily discharge volume and be able to handle 83,280 m3 of stormwater runoff in a 24 hour period. The design allowed all water flow within the system to be driven entirely by gravity. The CWTS for A-01 outfall is composed of eight one-acre wetland cells connected in pairs and planted with giant bulrush to provide continuous organic matter input to the system. The retention basin was designed to hold stormwater flow and to allow controlled discharge to the wetland. The system became operational in October of 2000 and is the first wetland treatment system permitted by South Carolina DHEC for removal of metals. Because of the exceptional performance of the A-01 CWTS, the same strategy was used to improve water quality of the H-02 outfall that receives discharge and stormwater from the Tritium Area of SRS. The primary contaminantstium Area of SRS. The primary contaminants in this outfall were also copper and zinc. The design for this second system required that the wetland treat the average discharge volume of 415 m3 per day, and be able to handle 9,690 m3 of stormwater runoff in a 24 hour period. This allowed the building of a system much smaller than the A-01 CWTS. The system became operational in July 2007. Metal removal has been excellent since water flow through the treatment systems began, and performance improved with the maturation of the vegetation during the first season of growth of each system. Sediment samples after the first and third years of operation indicated that copper was being bound in the sediments very rapidly after entering the treatment system. The design of the system encourages low redox and sulfide production in the sediments. The objective is to stabilize metals, including mercury, as sulfide compounds in the sediments. Costs for maintenance and operation of the systems are minimal, consisting primarily of ensuring that the pipes are not clogged and that water is flowing through the system. The treatment cost per thousand gallons is many times less than conventional wastewater treatment facilities. Life expectancy and function of the biological system is based on the life of the engineering aspects and not the wetland ecology.

    Despite the recognized importance of feedback in education, student satisfaction with the feedback process in medical and veterinary programs is often disappointing. We undertook various initiatives to try to improve the feedback culture in the final clinical year of the veterinary program at the University of Bristol, focusing on formative verbal feedback. The initiatives included E-mailed guidelines to staff and students, a faculty development workshop, and a reflective portfolio task for students. Following these initiatives, staff and students were surveyed regarding their perceptions of formative feedback in clinical rotations, and focus groups were held to further explore issues. The amount of feedback appeared to have increased, along with improved recognition of feedback by students and increased staff confidence and competence in the process. Other themes that emerged included inconsistencies in feedback among staff and between rotations; difficulties with giving verbal feedback to students, particularly when it relates to professionalism; the consequences of feedback for both staff and students; changes and challenges in students' feedback-seeking behavior; and the difficulties in providing accurate, personal end-of-rotation assessments. This project has helped improve the feedback culture within our clinics; the importance of sustaining and further developing the feedback culture is discussed in this article. PMID:24686719

  7. Automated Data Mining of A Proprietary Database System for Physician Quality Improvement

    International Nuclear Information System (INIS)

    Purpose: Physician practice quality improvement is a subject of intense national debate. This report describes using a software data acquisition program to mine an existing, commonly used proprietary radiation oncology database to assess physician performance. Methods and Materials: Between 2003 and 2004, a manual analysis was performed of electronic portal image (EPI) review records. Custom software was recently developed to mine the record-and-verify database and the review process of EPI at our institution. In late 2006, a report was developed that allowed for immediate review of physician completeness and speed of EPI review for any prescribed period. Results: The software extracted >46,000 EPIs between 2003 and 2007, providing EPI review status and time to review by each physician. Between 2003 and 2007, the department EPI review improved from 77% to 97% (range, 85.4-100%), with a decrease in the mean time to review from 4.2 days to 2.4 days. The initial intervention in 2003 to 2004 was moderately successful in changing the EPI review patterns; it was not repeated because of the time required to perform it. However, the implementation in 2006 of the automated review tool yielded a profound change in practice. Using the software, the automated chart review required ?1.5 h for mining and extracting the data for the 4-year period. Conclusion: This study quantified the EPI review process as it evolved during a 4-year period at our institution and found that automatt our institution and found that automation of data retrieval and review simplified and facilitated physician quality improvement

    Full Text Available Abstract Background Physicians and medical educators have repeatedly acknowledged the inadequacy of communication skills training in the medical school curriculum and opportunities to improve these skills in practice. This study of a controlled intervention evaluates the effect of teaching practicing physicians the skill of "agenda-setting" on patients' experiences with care. The agenda-setting intervention aimed to engage clinicians in the practice of initiating patient encounters by eliciting the full set of concerns from the patient's perspective and using that information to prioritize and negotiate which clinical issues should most appropriately be dealt with and which (if any should be deferred to a subsequent visit. Methods Ten physicians from a large physician organization in California with baseline patient survey scores below the statewide 25th percentile participated in the agenda-setting intervention. Eleven physicians matched on baseline scores, geography, specialty, and practice size were selected as controls. Changes in survey summary scores from pre- and post-intervention surveys were compared between the two groups. Multilevel regression models that accounted for the clustering of patients within physicians and controlled for respondent characteristics were used to examine the effect of the intervention on survey scale scores. Results There was statistically significant improvement in intervention physicians' ability to "explain things in a way that was easy to understand" (p = 0.02 and marginally significant improvement in the overall quality of physician-patient interactions (p = 0.08 compared to control group physicians. Changes in patients' experiences with organizational access, care coordination, and office staff interactions did not differ by experimental group. Conclusion A simple and modest behavioral training for practicing physicians has potential to positively affect physician-patient relationship interaction quality. It will be important to evaluate the effect of more extensive trainings, including those that work with physicians on a broader set of communication techniques.

    2011-01-01

    Resonant micro and nano strings are of interest for sensor applications due to their extraordinary high quality factors, low mass and tunable resonant frequency. It has been found that the quality factor of strings is usually limited by clamping loss. In this work, clamping loss has been addressed by varying the clamping design and string geometry. We present silicon nitride micro strings with quality factors (Q) of up to 4 million in high vacuum achieved by minimizing clamping loss. For applications such as for chemical sensing, strings need to vibrate at atmospheric pressure. Maximal quality factor values in air were measured for the shortest strings with the highest resonant frequency having an optimal width to height ratio.

    2010-09-01

    Full Text Available In our lives are governed by large, complex systems with increasingly complex software, and the safety, security, and reliability of these systems has become a major concern. As the software in today’ssystems grows larger, it has more defects, and these defects adversely affect the safety, security, and reliability of the systems. Software engineering is the application of a systematic, disciplined, quantifiable approach to the development, operation, andmaintenance of software. Software divides into two pieces: internal and external quality characteristics.External quality characteristics are those parts of a product that face its users, where internal quality characteristics are those that do not.Quality is conformance to product requirements and should be free. This research concerns the role of software Quality. Software reliability is an important facet of software quality. It is the probability of failure-freeoperation of a computer program in a specified environment for a specified time. In software reliability modeling, the parameters of the model are typically estimated from the test data of the corresponding component. However, the widely used point estimatorsare subject to random variations in the data, resulting in uncertainties in these estimated parameters. This research describes a new approach to the problem of software testing. The approach is based on Bayesian graphical models and presents formal mechanisms forthe logical structuring of the software testing problem, the probabilistic and statistical treatment of the uncertainties to be addressed, the test design and analysis process, and the incorporation and implication of test results. Once constructed, the models produced are dynamic representations of the software testingproblem. It explains need of the common test-and-fix software quality strategy is no longer adequate, and characterizes the properties of the quality strategy.

  19. Improving Patent Quality through Pre-grant Opposition in Thailand

    Directory of Open Access Journals (Sweden)

    2013-09-01

    Full Text Available Quality control in granting patents is a strong concern nowadays because granting patents without effective quality control will lead to negative spillover effects on competition, innovation, and the economy and adversely affect the public interest. More often than not, patent quality suffers from a poorly conducted examination process arising from lack of resources and information. Further, overburdened patent offices are another factor in low-quality patents. Pre-grant and post-grant opposition help in overcoming these problems by allowing third parties or interested persons to monitor patentability subject matters. Only innovations with valuable technology are worthy of receiving exclusive protection under patent law. Because each type of opposition has its relative merits and demerits, a country that wants to adopt the opposition process must take all factors into account including its domestic patent law. Thailand is one of the developing countries located in South East Asia that has adopted a pre-grant opposition system. In place for several years, it has seen plenty of oppositions and patent application appeals. This article considers the efficiency of the pre-grant opposition process in decisions of the Thai Board of Patents. An in-depth examination and analysis undertaken in the article points to the fact that although patent quality is in the eye of the beholder, pre-grant opposition proceedings in Thailand, when incorporated in legislation, increase patent quality, in return bettering innovation for the public benefit.

    Full Text Available Poor-quality images mostly result in spurious or missing features, which further degrade the overall performance of fingerprint recognition systems. This paper proposes a reconfigurable scheme of quality checks at two different levels: i at raw image level and ii at feature level. At first level, ellipse properties are calculated through analysis of statistical attributes of the captured raw image. At second level, the singularity points (core and delta are identified and extracted (if any. These information, as quality measures, are used in a cascaded manner to block/pass the image. This model is tested on both publicly available (Cross Match Verifier 300 sensor as well as proprietary (Lumidigm Venus V100 OEM Module sensor fingerprint databases scanned at 500 dpi. The experimental results show that this cascaded arrangement of quality barricades could correctly block poor quality images and hence elevated the overall system accuracy: with quality checks, both FNMR and FMR significantly dropped to 9.52% and 0.26% respectively for Cross Match Dataset and 2.17% and 2.16% respectively for Lumidigm Dataset.

    Full Text Available Abstract Background It is arguable that modification of diet, given its potential for positive health outcomes, should be widely advocated and adopted. However, food intake, as a basic human need, and its modification may be accompanied by sensations of both pleasure and despondency and may consequently affect to quality of life (QoL. Thus, the feasibility and success of dietary changes will depend, at least partly, on whether potential negative influences on QoL can be avoided. This is of particular importance in the context of dietary intervention studies and in the development of new food products to improve health and well being. Instruments to measure the impact of nutrition on quality of life in the general population, however, are few and far between. Therefore, the aim of this project was to develop an instrument for measuring QoL related to nutrition in the general population. Methods and results We recruited participants from the general population and followed standard methodology for quality of life instrument development (identification of population, item selection, n = 24; item reduction, n = 81; item presentation, n = 12; pretesting of questionnaire and initial validation, n = 2576; construct validation n = 128; and test-retest reliability n = 20. Of 187 initial items, 29 were selected for final presentation. Factor analysis revealed an instrument with 5 domains. The instrument demonstrated good cross-sectional divergent and convergent construct validity when correlated with scores of the 8 domains of the SF-36 (ranging from -0.078 to 0.562, 19 out of 40 tested correlations were statistically significant and 24 correlations were predicted correctly and good test-retest reliability (intra-class correlation coefficients from 0.71 for symptoms to 0.90. Conclusions We developed and validated an instrument with 29 items across 5 domains to assess quality of life related to nutrition and other aspects of food intake. The instrument demonstrated good face and construct validity as well as good reliability. Future work will focus on the evaluation of longitudinal construct validity and responsiveness.

  2. Waste Management Improvement Initiatives at Atomic Energy of Canada Limited - 13091

    International Nuclear Information System (INIS)

    Atomic Energy of Canada Limited's (AECL) Chalk River Laboratories (CRL) has been in operation for over 60 years. Radioactive, mixed, hazardous and non-hazardous wastes have been and continue to be generated at CRL as a result of research and development, radioisotope production, reactor operation and facility decommissioning activities. AECL has implemented several improvement initiatives at CRL to simplify the interface between waste generators and waste receivers: - Introduction of trained Waste Officers representing their facilities or activities at CRL; - Establishment of a Waste Management Customer Support Service as a Single-Point of Contact to provide guidance to waste generators for all waste management processes; and - Implementation of a streamlined approach for waste identification with emphasis on early identification of waste types and potential disposition paths. As a result of implementing these improvement initiatives, improvements in waste management and waste transfer efficiencies have been realized at CRL. These included: 1) waste generators contacting the Customer Support Service for information or guidance instead of various waste receivers; 2) more clear and consistent guidance provided to waste generators for waste management through the Customer Support Service; 3) more consistent and correct waste information provided to waste receivers through Waste Officers, resulting in reduced time and resources required for waste management (i.e., overall cost); 4) improved waste minimization and segregation approaches, as identified by in-house Waste Officers; and 5) enhanced communication between waste generators and waste management groups.

    The effects of crystallized phenol treatment of pilonidal sinus on quality of life has not been investigated before. This study aimed to compare the phenol treatment with surgical excision plus primary closure technique in terms of life quality by means of a life quality questionnaire. This is a prospective randomized clinical study. The study was conducted at Training and Teaching Hospital, Kayseri, Turkey. In total, 40 patients with pilonidal disease were randomly assigned into 2 clinically comparable groups between September 2010 and June 2011. Cristallyzed phenol application was done to 20 patients and surgical excision plus primary closure was done to 20 patients for the treatment of pilonidal disease. Data regarding demographic variables were recorded. To evaluate quality of life and patient comfort all patients asked to fill the questionnaire after complete healing occurred. There was no difference between the groups in age, sex and occupation. Two of the 20 patients in the excision and primary closure group had complication of wound dehiscience and needed prolonged wound care. There was significant differences in favor of the phenol group in all terms of life quality except for complete healing time. As a first degree treatment, phenol treatment is better than the other treatment choices of pilonidal disease in terms of time off work perioperative pain, being away from school and social life. Also phenol treatment can be done without any pretreatment laboratory examination. Further studies will be needed about cost-effectivity of phenol treatment. PMID:24799790

  7. Quality Improvement of Yarn by Automatic Waste Removal in Autoconer

    2013-02-01

    Full Text Available Spinning is the process of conversion of fibre into yarn. The spinning process includes various operations such as cotton mixing, carding, combing, drawing, winding. Winding is the final process in spinning mill where the yarn of small quantity is wound into a big package known as cones. The important aspect in winding is removal of defects or faults in yarn produced. In manual winding when there is discontinuity of thread, during removal of faults, the knot is made by a human. This reduces the quality of yarn. To overcome this disadvantage, autoconer is used. Autoconer is an advanced machine used in winding process to get a high quality yarn with low man power. Here, threads are spliced automatically. Splicing means the process of opening of broken ends and retwisting the ends after the removal of faults. Here the joined yarn looks like parent yarn. Thus, the quality of yarn is enhanced. The drawback of autoconer is, waste collected by suction motor gets deposited on the suction panel and it should be disposed manually for a periodic time interval. If the waste is not removed it reduces the operating efficiency of the suction motor. This leads to reduction in quality of yarn. The aim of the proposed work is to design an automatic waste removal system using PLC (Programmable Logic Controller which helps us to further increase the efficiency of the suction motor and thus the quality of yarn.

  8. Water Quality Improvement Policies: Lessons Learned from the Implementation of Proposition O in Los Angeles, California

    2009-03-01

    This article evaluates the implementation of Proposition O, a stormwater cleanup measure, in Los Angeles, California. The measure was intended to create new funding to help the city comply with the Total Maximum Daily Load requirements under the federal Clean Water Act. Funding water quality objectives through a bond measure was necessary because the city had insufficient revenues to deploy new projects in its budget. The bond initiative required a supermajority vote (two-thirds of the voters), hence the public had to be convinced that such funding both was necessary and would be effective. The bond act language included project solicitation from the public, as well as multiple benefit objectives. Accordingly, nonprofit organizations mobilized to present projects that included creating new parks, using schoolyards for flood control and groundwater recharge, and replacing parking lots with permeable surfaces, among others. Yet few, if any, of these projects were retained for funding, as the city itself also had a list of priorities and higher technical expertise in justifying them as delivering water quality improvements. Our case study of the implementation of Proposition O points to the potentially different priorities for the renovation of urban infrastructure that are held by nonprofit organizations and city agencies and the importance of structuring public processes clearly so that there are no misimpressions about funding and implementation responsibilities that can lead to disillusionment with government, especially under conditions of fiscal constraints.

  9. The cost-effectiveness of using financial incentives to improve provider quality: a framework and application

    2014-01-01

    Despite growing adoption of pay-for-performance (P4P) programmes in health care, there is remarkably little evidence on the cost-effectiveness of such schemes. We review the limited number of previous studies and critique the frameworks adopted and the narrow range of costs and outcomes considered, before proposing a new more comprehensive framework, which we apply to the first P4P scheme introduced for hospitals in England. We emphasise that evaluations of cost-effectiveness need to consider who the residual claimant is on any cost savings, the possibility of positive and negative spillovers, and whether performance improvement is a transitory or investment activity. Our application to the Advancing Quality initiative demonstrates that the incentive payments represented less than half of the 13m pound total programme costs. By generating approximately 5200 quality-adjusted life years and 4.4m pound of savings in reduced length of stay, we find that the programme was a cost-effective use of resources in its first 18months.

    Full Text Available Excessive cholesterol and fatty acids in the diet can lead to cardiovascular disease. Recent studies have reported that elevated Angiopoietin-Like Protein 3 (ANGPTL3 expression contributes to dyslipidemia. The aim of the study was to examine the beneficial effect of icariin, an active flavonoid glucoside, on meat quality in swines and the mechanisms involved. About 36 Duroc x Landrace x Yorkshire swines with an initial average body weight 65 kg were randomly divided into 3 groups: control swines group, two groups of icariin-treated swines (0.1 or 0.3%. About 42 days after, icariin (0.1 or 0.3% treatment significantly decreased fat meat percentage, drip loss rate, plasma and hepatic total cholesterol levels, plasma and hepatic triglyceride concentrations, expression of ANGPTL3 mRNA and increased meat color, lean meat percentage, plasma high-density lipoprotein cholesterol level, activity of Lipoprotein Lipase (LPL. The present results suggest that icariin changes ANGPTL3 expression and LPL activity to improve meat quality in swine.

    In head and neck surgery, minimally invasive approaches have been typically avoided due to concerns about visualization, possible damage to vital structures, and limited availability of effective instrumentation. The incorporation of robotic technology in surgery is now an accepted fact, and because of the complexities of certain laparoscopic procedures, the extended capabilities offered by robotic technology have gained wide acceptance. We report the case of a patient who underwent a robotic total thyroidectomy using a gasless right transaxillary approach. This technique provides a high quality image leading to improved visualization of vital structures during thyroidectomy with the added advantage of avoidance of a neck incision. Several issues regarding this technique remain to be clarified and evaluated in multicenter studies: patient selection, surgeon training and learning curve, postoperative morbidity due to recurrent nerve and parathyroid injury, long term oncologic and cosmetic results. However, we believe that robotic thyroid surgery using a gasless transaxillary approach will advance the frontiers of minimally invasive endocrine surgery. PMID:21095176

    Full Text Available Customer's satisfaction is the measure of quality of a product or a service. Customers' feedback are important sources of product information on performance, improvements, and enhancement of ideas. The implementation of customer feedback system is essential to enhance the customers' satisfaction through continual improvement, which is essential for the survival of any organisation in a competitive environment. This study provides a structured approach to analyse and translate the customers' feedback into quality improvement of the product. The defects reported by the customers' on the unmanned aerial vehicle Lakshya systems were investigated while carrying out their rectification. Prompt remedial measures were also instituted to prevent their recurrence. This has resulted in the improvement of reliability and quality of the product. Finally, the implementation of customer feedback system and formalisation of defect investigation procedure for improving the quality and reliability of Lakshya systems has been described. A case study on Barco monitors (RGD 651 hasalso been demonstrated from Lakshya experience.

    Quality assurance makes sure the project will be completed based on the previously approved specifications, standards and functionality. It is required without defects and possible problems. It monitors and tries to progress the development process from the start of the project. Software Quality Assurance (SQA) is the combination of the entire software development process, which includes software design, coding, source code control, code review, change management, configuration management and release management. In this paper we describe the solution for the key problems of software testing in quality assurance. The existing software practices have some problems such as testing practices, attitude of users and culture of organizations. All these tree problems have some combined problems such as shortcuts in testing, reduction in testing time, poor documentation etc. In this paper we are recommending strategies to provide solution of the said problems mentioned above.

    Multicenter clinical registries are increasingly recognized as valuable tools for establishing benchmarks, facilitating patient-centered quality improvement and research. In 2010, the Pediatric and Congenital Electrophysiology Society convened a taskforce of its members to design, construct, and implement a clinical registry known as the Multicenter Pediatric and Adult Congenital EP Quality (MAP-IT) Initiative. The present aim of the MAP-IT Initiative is to create an infrastructure by which we can measurably improve patient-centered outcomes and reduce complications associated with electrophysiology studies and catheter ablation in pediatric and congenital heart disease patients. The purpose of this writing is to report the progress to date from three of the four subcommittees of the MAP-IT taskforce. Specifically, we present our initial set of key data elements and definitions, recommended database table structure, and considerations regarding wide-scale implementation of the registry. Development of a risk/complexity score for use in the MAP-IT registry is presented in a separate companion manuscript. It is our intent that these manuscripts will serve to introduce the electrophysiology and pediatric cardiology community to the MAP-IT initiative and provide a rationale for its design and recommended implementation strategy.

    We used the Legal-Institutional Analysis Model (LIAM) and Advocacy Coalition Framework (ACF) to analyze the campaign over passage of the Colorado Hogs Rule, an initiative passed by the voters in 1998 to require regulation of swine production facilities in Colorado. Used in tandem, LIAM and ACF provided an opportunity to develop a robust understanding of the obstacles and opportunities that face water quality managers in a state-centered multi-organizational decision process. We found that combining the LIAM with the ACF enhanced the understanding that could be achieved by using either model in isolation. The predictive capacity of the LIAM would have been reduced without information from the ACF, and the ACF by itself would have missed the importance of a single-case study.

  16. Mutation breeding for oil quality improvement in sunflower

    International Nuclear Information System (INIS)

    Although sunflower oil is appreciated as a high quality commodity, new emerging markets and increasing concern about health risks are demanding changes in the oil quality. The optimal quality of oils depends on their intended use either for food or non-food applications. The fatty acid composition and the total content and profile of tocopherols have been the most important traits considered in breeding for oil quality. Applications demanding a high nutritional value (salad oil) require a reduction of saturated fatty acids and enhancement of the vitamin E (alpha-tocopherol) content of the oil. The use of oils in the food industry requiring plastic fats (margarines) demand an increased concentration of saturated fatty acids to avoid hydrogenation. High temperature processes (frying, biolubricants) need oils highly resistant to thermoxidation, with a high concentration of oleic acid and antioxidants (gamma- and delta-tocopherol). In sunflower, the utilization of mutagenesis has been the most successful procedure used to generate genetic variability for these quality components. The mutagenic treatment is usually applied to seeds to obtain M1 generation and mutants are detected analysing M2 half seeds, allowing identification of mutants in one year. The most valuable sunflower oil quality mutants produced have been the high oleic acid mutant (>80%), high levels of either palmitic or stearic acid (>25%), low total saturated fatty acids and increased total saturated fatty acids and increased levels of beta- (>65%), gamma- (>95%), and delta-tocopherol (>45%). The novel traits are in all cases governed by a reduced number of genes, which facilitates their management in plant breeding. All this induced variation opens up the possibility of tailoring specialty sunflower oils for specific food and nonfood applications (author)

    Full Text Available Abstract Background Recent educational initiatives by both the World Health Organization and the American Association of Medical Colleges have endorsed integrating teaching of patient safety and quality improvement (QI to medical students. Curriculum development should take into account learners’ attitudes and preferences. We surveyed students to assess preferences and attitudes about QI and patient safety education. Methods An electronic survey was developed through focus groups, literature review, and local expert opinion and distributed via email to all medical students at a single medical school in the spring of 2012. Results A greater proportion of students reported previous exposure to patient safety than to quality improvement topics (79% vs. 47%. More than 80% of students thought patient safety was of the same or greater importance than basic science or clinical skills whereas quality improvement was rated as the same or more important by about 70% of students. Students rated real life examples of quality improvement projects and participation in these projects with actual patients as potentially the most helpful (mean scores 4.2/5 and 3.9/5 respectively. For learning about patient safety, real life examples of mistakes were again rated most highly (mean scores 4.5/5 for MD presented mistakes and 4.1/5 for patient presented mistakes. Students rated QI as very important to their future career regardless of intended specialty (mean score 4.5/5. Conclusions Teaching of patient safety and quality improvement to medical students will be best received if it is integrated into clinical education rather than solely taught in pre-clinical lectures or through independent computer modules. Students recognize that these topics are important to their careers as future physicians regardless of intended specialty.

  19. Leaching Pretreatments for Improving Biomass Quality: Feedstocks, Solvents, and Extraction Modeling

    Yu, Chao Wei

    In this research, a systematic study was conducted to quantify the inorganic and organic compounds leached from rice straw, wheat straw, corn stover, switchgrass, Jose Tall Wheatgrass, Douglas fir, and Miscanthus with water, and to evaluate the feedstock quality and characteristics of leached solids for thermal process applications. Leaching feedstocks with water at ambient temperature with a 20 L/kg (dry matter) ratio for 2 hours greatly increased the ash fusion temperature of rice straw (from 1050°C to above 1550°C) and wheat straw (from 900°C to 1250°C), but the treatment only increased the ash fusion temperature of corn stover from 900°C to 950°C. Miscanthus had relatively good initial feedstock quality and leaching may not prove necessary for this feedstock in thermal systems. Leaching also changed the combustion kinetics of biomass by increasing the initial degradation temperature of most feedstocks from originally between 165°C and 186°C to between 180°C and 250°C depending on feedstock. Moreover, leaching increased the maximum rate of weight loss of feedstock by 11% to 54% and increased the corresponding temperatures for peak loss up to 34°C. Leaching removed a sizeable fraction of organic compounds (between 2% and 12% of dry matter). These organic extracts were identified as mostly sugars and acids which might be valuable co-products. Moisture contents of feedstocks after leaching were typically high, ranging between 68 and 81% wet basis. A dewatering step is generally required prior to using the leached biomass for thermochemical conversion. Solvents with ability to dissolve ion-exchangeable, organically associated, and acid soluble metals can further remove non-water soluble metals from biomass and may also improve feedstock quality. In a solvent evaluation, corn stover and wheat straw were leached with water, 1M ammonium acetate, 1M HCl, 100% methanol, 50% methanol, 100% ethanol, and 50% ethanol, and leached solids and leachate were characterized. Among these solvents, 1M HCl improved the corn stover feedstock quality better than other solvents investigated while water worked better for wheat straw. The results show that 1M HCl increased the ash fusion temperature of corn stover from 900 to 1300°C and above 1550°C for water-treated wheat straw. Leachability of each ion extracted from corn stover and wheat straw with different solvents was determined, and the results may be useful in studying the solubility of different elements in a complex ionic solution like leachate. A parallel diffusion model was developed from Fick's second law of diffusion to describe the mass transfer of compounds extracted from biomass to the bulk liquid phase. The model describes two leaching steps with two effective diffusion coefficients, the first step being an initial washing and fast diffusion ( Dfast) followed by a second slower intraparticle diffusion (Dslow). Mass concentration profiles of anions, cations, and sugars leached from wheat straw with water were developed and were used to estimate parameters in the model and for model validation. Results show that Dfast increased as leaching temperature increased while the effects of leaching ratio on Dfast and Dslow were inconclusive. The calculated Dfast and Dslow for leaching ions and sugars from wheat straw did not follow an Arrhenius behavior, suggesting that the effective diffusion coefficients were different depending on batch leaching conditions. In general, the model was able to predict the concentrations of selected anions, cations and total sugars leached from wheat straw with R2 between 0.85 and 0.99 from linear regression analysis of the experimental data versus predicted data. However, the predictability of the model significantly decreased when employing as low a leaching ratio as 15 L/kg due to the high solids concentration of the slurry and resulting inability to apply sufficient agitation. The model tended to overestimate the concentrations of ions in leachate and underestimate the total sugars during the initial 6 minutes of leaching, possibly due t

  20. Association of initial CT findings with quality-of-life outcomes for traumatic brain injury in children

    International Nuclear Information System (INIS)

    Traumatic brain injury (TBI) is a leading cause of acquired disability in children and adolescents. To demonstrate the association between specific findings on initial noncontrast head CT and long-term outcomes in children who have suffered TBI. This was an IRB-approved prospective study of children ages 2-17 years treated in emergency departments for TBI and who underwent a head CT as part of the initial work-up (n = 347). The change in quality of life at 12 months after injury was measured by the PedsQL scale. Children with TBI who had intracranial injuries identified on the initial head CT had a significantly lower quality-of-life scores compared to children with TBI whose initial head CTs were normal. In multivariate analysis, children whose initial head CT scans demonstrated intraventricular hemorrhage, parenchymal injury, midline shift ?5 mm, hemorrhagic shear injury, abnormal cisterns or subdural hematomas ?3 mm had lower quality of life scores 1 year after injury than children whose initial CTs did not have these same injuries. Associations exist between findings from the initial noncontrast head CT and quality of life score 12 months after injury in children with TBI. (orig.)
