Methods for the Economic Evaluation of Health Care Programmes, Second Edition

Abstract: We are witnessing a paradigm shift in the way medicine is practiced, taught, and evaluated. It was relatively recently that medicine knew no limits. New diagnostic procedures led to more medical and surgical procedures and to greater expense. It was assumed that patients would be the recipient of these advances. However, the uncontrolled costs of medical care and the poor documentation of patient benefit ushered in a new era of cost conscientiousness. Now, there is a need to show that medicine produces value for money. As a result, new methodologies such as cost-effectiveness analysis, cost-benefit analysis, and cost-utility analysis have become commonplace in medical journals. This has created a need to revise medical education and postgraduate training in order to accommodate new methodologies and new controversies. Within the last few years, several influential publications have emerged. Perhaps the most important of these is the book Cost-Effectiveness in Health and Medicine edited by Martha Gold and colleagues.1 This book summarizes the consensus of an expert panel convened to review cost-effectiveness analysis in health care. The Gold book covers the theory but does not teach the methods. Methods for the Economic Evaluation of Health Care Programmes by Michael Drummond and colleagues offers specific, step-by-step methodologies for conducting economic evaluations. This is the second edition of a book originally published in 1987. During the ten years between editions, there were very substantial advances in theory and methods for economic evaluations of health care programs. The revised edition brings the text up to date. Methods for the Economic Evaluation of Health Care Programmes arises from the teaching of health economics at McMaster University. The McMaster Centre for Health Economics and Policy Analysis is internationally regarded as a focal point for economic evaluations of health care. Among other advances, researchers at the Centre have produced a widely used methodology, known as the Health Utilities Index, for estimating the cost/utility of health programs. The book was originally developed for a course at McMaster and for a workshop offered by the McMaster faculty. The second edition adds one new author (Bernie O’Brien) who has more recently joined the McMaster faculty. The second edition also introduces substantial changes in the chapters on cost-effectiveness, cost-utility, and cost-benefit analysis. These are important improvements because of the profound methodological developments in these areas. In addition, the second edition includes new chapters on collection and analysis of data and on the presentation and use of data. These new chapters add discussion on the pros and cons of economic evaluations and on some of the difficulties in the interpretation of economic data. In addition, the second edition includes many more boxes and illustrations to facilitate the interpretation of the text. Perhaps the greatest contribution of the book is the very detailed presentation of cost/utility analysis. It is now common to offer discussions of the cost to produce a year of life adjusted for life quality. This is known as a quality adjusted life year (QALY). There are a variety of different methods for estimating QALYs. Nevertheless, QALYs estimated using different methods are often found in the same comparison or “league” table. This book goes into considerable detail in how QALYs are estimated and describes some of the methodological issues and problems in estimating these outcomes. Unlike other texts, the book provides systematic stepby-step instruction in how both costs and health benefits can be estimated. In summary, the role of health economics is becoming firmly established in the evaluation of health care programs. In combination with Gold and colleagues’ book,1 which provides a detailed theoretical discussion of economic analysis, Methods for the Economic Evaluation of Health Care Programmes offers systematic training in the application of economic methodologies. This book can serve as a basic text for students hoping to understand the complex methodologies of economic evaluation. In addition, the book is a handy reference for advanced practitioners of economic analysis.

Why patients use alternative medicine : results of a national study

Abstract: Context.—Research both in the United States and abroad suggests that significant numbers of people are involved with various forms of alternative medicine. However, the reasons for such use are, at present, poorly understood.Objective.—To investigate possible predictors of alternative health care use.Methods.—Three primary hypotheses were tested. People seek out these alternatives because (1) they are dissatisfied in some way with conventional treatment; (2) they see alternative treatments as offering more personal autonomy and control over health care decisions; and (3) the alternatives are seen as more compatible with the patients' values, worldview, or beliefs regarding the nature and meaning of health and illness. Additional predictor variables explored included demographics and health status.Design.—A written survey examining use of alternative health care, health status, values, and attitudes toward conventional medicine. Multiple logistic regression analyses were used in an effort to identify predictors of alternative health care use.Setting and Participants.—A total of 1035 individuals randomly selected from a panel who had agreed to participate in mail surveys and who live throughout the United States.Main Outcome Measure.—Use of alternative medicine within the previous year.Results.—The response rate was 69%.The following variables emerged as predictors of alternative health care use: more education (odds ratio [OR], 1.2; 95% confidence interval [CI], 1.1-1.3); poorer health status (OR, 1.3; 95% CI, 1.1-1.5); a holistic orientation to health (OR, 1.4; 95% CI, 1.1-1.9); having had a transformational experience that changed the person's worldview (OR, 1.8; 95% CI, 1.3-2.5); any of the following health problems: anxiety (OR, 3.1; 95% CI, 1.6-6.0); back problems (OR, 2.3; 95% CI, 1.7-3.2); chronic pain (OR, 2.0; 95% CI, 1.1-3.5); urinary tract problems (OR, 2.2; 95% CI, 1.3-3.5); and classification in a cultural group identifiable by their commitment to environmentalism, commitment to feminism, and interest in spirituality and personal growth psychology (OR, 2.0; 95% CI, 1.4-2.7). Dissatisfaction with conventional medicine did not predict use of alternative medicine. Only 4.4% of those surveyed reported relying primarily on alternative therapies.Conclusion.—Along with being more educated and reporting poorer health status, the majority of alternative medicine users appear to be doing so not so much as a result of being dissatisfied with conventional medicine but largely because they find these health care alternatives to be more congruent with their own values, beliefs, and philosophical orientations toward health and life.

Chronic disease management: what will it take to improve care for chronic illness?

Abstract: M eeting the complex needs of patients with chronic illness or impairment is the single greatest challenge facing organized medical practice. Usual care is not doing the job; dozens of surveys and audits have revealed that sizable proportions of chronically ill patients are not receiving effective therapy, have poor disease con- trol, and are unhappy with their care (1). Results of randomized trials also show that effective disease management programs can achieve substantially better outcomes than usual care, the control intervention. These trials, along with the ideas and efforts for improvement discussed in this issue, show that we can improve care and outcomes. As the articles suggest, these improvements will not come easily. If we are to improve care for most patients with chronic illness, the evidence strongly suggests that we reshape our ambulatory care systems for this purpose. Pri- mary care practice was largely designed to provide ready access and care to patients with acute, varied problems, with an emphasis on triage and patient flow; short appointments; diagnosis and treatment of symptoms and signs; reliance on laborato- ry investigations and prescriptions; brief, didactic patient education; and patient- initiated follow-up. Patients and families struggling with chronic illness have differ- ent needs, and these needs are unlikely to be met by an acute care organization and culture. They require planned, regular interactions with their caregivers, with a focus on function and prevention of exacerbations and complications. This interac- tion includes systematic assessments, attention to treatment guidelines, and behav- iorally sophisticated support for the patient's role as self-manager. These interactions must be linked through time by clinically relevant information systems and continu- ing follow-up initiated by the medical practice. Comprehensive System Change

Effects of Computer-Based Clinical Decision Support Systems on Physician Performance and Patient Outcomes: A Systematic Review

Abstract: Context.—Many computer software developers and vendors claim that their systems can directly improve clinical decisions. As for other health care interventions, such claims should be based on careful trials that assess their effects on clinical performance and, preferably, patient outcomes.Objective.—To systematically review controlled clinical trials assessing the effects of computer-based clinical decision support systems (CDSSs) on physician performance and patient outcomes.Data Sources.—We updated earlier reviews covering 1974 to 1992 by searching the MEDLINE, EMBASE, INSPEC, SCISEARCH, and the Cochrane Library bibliographic databases from 1992 to March 1998. Reference lists and conference proceedings were reviewed and evaluators of CDSSs were contacted.Study Selection.—Studies were included if they involved the use of a CDSS in a clinical setting by a health care practitioner and assessed the effects of the system prospectively with a concurrent control.Data Extraction.—The validity of each relevant study (scored from 0-10) was evaluated in duplicate. Data on setting, subjects, computer systems, and outcomes were abstracted and a power analysis was done on studies with negative findings.Data Synthesis.—A total of 68 controlled trials met our criteria, 40 of which were published since 1992. Quality scores ranged from 2 to10, with more recent trials rating higher (mean, 7.7) than earlier studies (mean, 6.4) (P<.001). Effects on physician performance were assessed in 65 studies and 43 found a benefit (66%). These included 9 of 15 studies on drug dosing systems, 1 of 5 studies on diagnostic aids, 14 of 19 preventive care systems, and 19 of 26 studies evaluating CDSSs for other medical care. Six of 14 studies assessing patient outcomes found a benefit. Of the remaining 8 studies, only 3 had a power of greater than 80% to detect a clinically important effect.Conclusions.—Published studies of CDSSs are increasing rapidly, and their quality is improving. The CDSSs can enhance clinical performance for drug dosing, preventive care, and other aspects of medical care, but not convincingly for diagnosis. The effects of CDSSs on patient outcomes have been insufficiently studied.

Persistent pain and well-being: a World Health Organization Study in Primary Care.

Abstract: Context.—There is little information on the extent of persistent pain across cultures. Even though pain is a common reason for seeking health care, information on the frequency and impacts of persistent pain among primary care patients is inadequate.Objective.—To assess the prevalence and impact of persistent pain among primary care patients.Design and Setting.—Survey data were collected from representative samples of primary care patients as part of the World Health Organization Collaborative Study of Psychological Problems in General Health Care, conducted in 15 centers in Asia, Africa, Europe, and the Americas.Participants.—Consecutive primary care attendees between the age of majority (typically 18 years) and 65 years were screened (n=25916) and stratified random samples interviewed (n=5438).Main Outcome Measures.—Persistent pain, defined as pain present most of the time for a period of 6 months or more during the prior year, and psychological illness were assessed by the Composite International Diagnostic Interview. Disability was assessed by the Groningen Social Disability Schedule and by activity-limitation days in the prior month.Results.—Across all 15 centers, 22% of primary care patients reported persistent pain, but there was wide variation in prevalence rates across centers (range, 5.5%-33.0%). Relative to patients without persistent pain, pain sufferers were more likely to have an anxiety or depressive disorder (adjusted odds ratio [OR], 4.14; 95% confidence interval [CI], 3.52-4.86), to experience significant activity limitations (adjusted OR, 1.63; 95% CI, 1.41-1.89), and to have unfavorable health perceptions (adjusted OR, 1.26; 95% CI, 1.07-1.49). The relationship between psychological disorder and persistent pain was observed in every center, while the relationship between disability and persistent pain was inconsistent across centers.Conclusions.—Persistent pain was a commonly reported health problem among primary care patients and was consistently associated with psychological illness across centers. Large variation in frequency and the inconsistent relationship between persistent pain and disability across centers suggests caution in drawing conclusions about the role of culture in shaping responses to persistent pain when comparisons are based on patient samples drawn from a limited number of health care settings in each culture.

The urgent need to improve health care quality. Institute of Medicine National Roundtable on Health Care Quality.

Abstract: Objective.—To identify issues related to the quality of health care in the United States, including its measurement, assessment, and improvement, requiring action by health care professionals or other constituencies in the public or private sectors.Participants.—The National Roundtable on Health Care Quality, convened by the Institute of Medicine, a component of the National Academy of Sciences, comprised 20 representatives of the private and public sectors, practicing medicine and nursing, representing academia, business, consumer advocacy, and the health media, and including the heads of federal health programs. The roundtable met 6 times between February 1996 and January 1998. It explored ongoing, rapid changes in health care and the implications of these changes for the quality of health and health care in the United States.Evidence.—Roundtable members held discussions with a wide variety of experts, convened conferences, commissioned papers, and drew on their individual professional experience.Consensus Process.—At the end of its deliberations, roundtable members reached consensus on the conclusions described in this article by a series of discussions at committee meetings and reviews of successive draft documents, the first of which was created by the listed authors and the Institute of Medicine project director. The drafts were revised following these discussions, and the final document was approved according to the formal report review procedures of the National Research Council of the National Academy of Sciences.Conclusions.—The quality of health care can be precisely defined and measured with a degree of scientific accuracy comparable with that of most measures used in clinical medicine. Serious and widespread quality problems exist throughout American medicine. These problems, which may be classified as underuse, overuse, or misuse, occur in small and large communities alike, in all parts of the country, and with approximately equal frequency in managed care and fee-for-service systems of care. Very large numbers of Americans are harmed as a direct result. Quality of care is the problem, not managed care. Current efforts to improve will not succeed unless we undertake a major, systematic effort to overhaul how we deliver health care services, educate and train clinicians, and assess and improve quality.

A New Definition of Children With Special Health Care Needs

Abstract: * Abbreviations: MCH = : Maternal and Child Health (program) • CSHCN = : Children With Special Health Care Needs (program) • DSCSHCN = : (Maternal and Child Health Bureau's) Division of Services for Children With Special Health Care Needs. Developing community systems of services for children with special health care needs represents a significant challenge for pediatricians, families, managed care organizations, and public and private agencies providing services to this population. At the state level, Maternal and Child Health (MCH) and Children With Special Health Care Needs (CSHCN) programs are vested with the responsibility for planning and developing systems of care for all children with special health care needs. Historically, these programs have been supported through Title V of the Social Security Act, with state-matching funds, to provide health services to selected groups of children with special needs, typically those with complex physical conditions. However, during the last half-century, service systems have become increasingly complex as a result of health, education, and social policy changes, as well as changes in the epidemiology of child health, including increases in the number and proportion of children with chronic conditions and disabilities and changes in their case-mix.1-4 These changes have resulted in gaps in some service areas and duplication in other areas, as well as fragmentation in the way service systems are organized.5 Recognizing these difficulties, health policy leaders at the state and federal levels, with broad input from public and private agencies, providers, and families, effected legislative changes in the federal Omnibus Budget Reconciliation Act of 1989, which expanded the mission of CSHCN programs to facilitate the development of community-based systems of services for children with special health care needs and their families. Since then, the explosive growth of managed care has presented new challenges and opportunities as well as a heightened urgency for the development of systems of care that integrate health and related services for this population.6 7 Developing systems to serve children with special health care needs requires a clear definition of the population to … Address correspondence and reprint requests to: Merle McPherson, MD, Maternal and Child Health Bureau, Room 18A27, Parklawn Bldg, 5600 Fishers Ln, Rockville, MD 20857.

Variations in population health status: results from a United Kingdom national questionnaire survey.

Abstract: Objective: To measure the health of a representative sample of the population of the United Kingdom by using the EuroQoL EQ-5D questionnaire. Design: Stratified random sample representative of the general population aged 18 and over and living in the community. Setting: United Kingdom. Subjects: 3395 people resident in the United Kingdom. Main outcome measures: Average values for mobility, self care, usual activities, pain or discomfort, and anxiety or depression. Results: One in three respondents reported problems with pain or discomfort. There were differences in the perception of health according to the respondent9s age, social class, education, housing tenure, economic position, and smoking behaviour. Conclusions: The EQ-5D questionnaire is a practical way of measuring the health of a population and of detecting differences in subgroups of the population. Key messages Measurement of health outcome requires the observation of states of health Patients9 involvement in recording and assessing their own state of health is a major element in the process of evaluating the impact of health care The EuroQoL EQ-5D questionnaire highlights variations in states of health which are consistent with previously published results High degrees of pain are reported in the general population. A category for pain is absent and thus undetected in the survey of disability by the Office of Population Censuses and Surveys

Supporting autonomy to motivate patients with diabetes for glucose control

Abstract: OBJECTIVE We applied the self-determination theory of human motivation to examine whether patient perceptions of autonomy supportiveness (i.e., patient centeredness) from their diabetes care providers related to improved glucose control over a 12-month period. RESEARCH DESIGN AND METHODS We conducted a prospective cohort study of patients with diabetes from a diabetes treatment center at a university-affiliated community hospital. Participants were 128 patients between 18 and 80 years of age who took medication for diabetes, had no other major medical illnesses, and were responsible for monitoring their glucose and taking their medications. The main outcome measure was a change in HbA 1c values over the 12 months of the study. RESULTS Patient perception of autonomy support from a health care provider related to a change in HbA 1c values at 12 months ( P P P 1c values over 12 months ( P CONCLUSIONS The findings support the prediction of the self-determination theory that patients with diabetes whose health care providers are autonomy supportive will become more motivated to regulate their glucose levels, feel more able to regulate their glucose, and show improvements in their HbA 1c values.

Clinical governance and the drive for quality improvement in the new NHS in England

Abstract: A commitment to deliver high quality care should be at the heart of everyday clinical practice. In the past many health professionals have watched as board agendas and management meetings have become dominated by financial issues and activity targets. The government's white paper on the NHS in England outlines a new style of NHS that will redress this imbalance.1 For the first time, all health organisations will have a statutory duty to seek quality improvement through clinical governance. In the future, well managed organisations will be those in which financial control, service performance, and clinical quality are fully integrated at every level. #### Summary points Clinical governance is to be the main vehicle for continuously improving the quality of patient care and developing the capacity of the NHS in England to maintain high standards (including dealing with poor professional performance) It requires an organisation-wide transformation; clinical leadership and positive organisational cultures are particularly important Local professional self regulation will be the key to dealing with the complex problems of poor performance among clinicians New approaches are needed to enable the recognition and replication of good clinical practice to ensure that lessons are reliably learned from failures in standards of care The new concept has echoes of corporate governance, an initiative originally aimed at redressing failed standards in the business world through the Cadbury report2 and later extended to public services (including the NHS). The resonance of the two terms is important, for if clinical governance is to be successful it must be underpinned by the same strengths as corporate governance: it must be rigorous in its application, organisation-wide in its emphasis, accountable in its delivery, developmental in its thrust, and positive in its connotations. The introduction of clinical governance, aimed as it is at improving the quality of clinical care at …

Confidential inquiry into quality of care before admission to intensive care.

Abstract: Objective: To examine the prevalence, nature, causes, and consequences of suboptimal care before admission to intensive care units, and to suggest possible solutions. Design: Prospective confidential inquiry on the basis of structured interviews and questionnaires. Setting: A large district general hospital and a teaching hospital. Subjects: A cohort of 100 consecutive adult emergency admissions, 50 in each centre. Main outcome measures: Opinions of two external assessors on quality of care especially recognition, investigation, monitoring, and management of abnormalities of airway, breathing, and circulation, and oxygen therapy and monitoring. Results: Assessors agreed that 20 patients were well managed (group 1) and 54 patients received suboptimal care (group 2). Assessors disagreed on quality of management of 26 patients (group 3). The casemix and severity of illness, defined by the acute physiology and chronic health evaluation (APACHE II) score, were similar between centres and the three groups. In groups 1, 2, and 3 intensive care mortalities were 5 (25%), 26 (48%), and 6 (23%) respectively (P=0.04) (group 1 versus group 2, P=0.07). Hospital mortalities were 7 (35%), 30 (56%), and 8 (31%) (P=0.07) and standardised hospital mortality ratios (95% confidence intervals) were 1.23 (0.49 to 2.54), 1.4 (0.94 to 2.0), and 1.26 (0.54 to 2.48) respectively. Admission to intensive care was considered late in 37 (69%) patients in group 2. Overall, a minimum of 4.5% and a maximum of 41% of admissions were considered potentially avoidable. Suboptimal care contributed to morbidity or mortality in most instances. The main causes of suboptimal care were failure of organisation, lack of knowledge, failure to appreciate clinical urgency, lack of supervision, and failure to seek advice. Conclusions: The management of airway, breathing, and circulation, and oxygen therapy and monitoring in severely ill patients before admission to intensive care units may frequently be suboptimal. Major consequences may include increased morbidity and mortality and requirement for intensive care. Possible solutions include improved teaching, establishment of medical emergency teams, and widespread debate on the structure and process of acute care. Key messages Suboptimal management of oxygen therapy, airway, breathing, circulation, and monitoring before admission to intensive care occurred in over half of a consecutive cohort of acute adult emergency patients. This may be associated with increased morbidity, mortality, and avoidable admissions to intensive care At least 39% of acute adult emergency patients were admitted to intensive care late in the clinical course of the illness Major causes of suboptimal care included failure of organisation, lack of knowledge, failure to appreciate clinical urgency, lack of supervision, and failure to seek advice A medical emergency team may be useful in responding pre-emptively to the clinical signs of life threatening dysfunction of airway, breathing, and circulation, rather than relying on a cardiac arrest team The structure and process of acute care and their importance require major re-evaluation and debate

How Good Is the Quality of Health Care in the United States

Abstract: Studies over the past decade show that some people are receiving more care than they need, and some are receiving less. Simple averages from a number of studies indicate that 50 percent of people received recommended preventive care; 70 percent, recommended acute care; 30 percent, contraindicated acute care; 60 percent, recommended chronic care; and 20 percent, contraindicated chronic care. These studies strongly suggest that the care delivered in the United States often does not meet professional standards. Efforts to measure quality and report routinely on the results to the public at large would allow more definitive assessments of the status of the nation's health care and would enable us to single out the areas in need of improvement.

Translating Research Into Practice: The Schizophrenia Patient Outcomes Research Team (PORT) Treatment Recommendations

Abstract: Beginning in 1992, the Agency for Health Care Policy and Research and the National Institute of Mental Health funded the Schizophrenia Patient Outcomes Research Team (PORT) to develop and disseminate recommendations for the treatment of schizophrenia based on existing scientific evidence. These Treatment Recommendations, presented here in final form for the first time, are based on exhaustive reviews of the treatment outcomes literature (previously published in Schizophrenia Bulletin, Vol. 21, No. 4, 1995) and focus on those treatments for which there is substantial evidence of efficacy. The recommendations address antipsychotic agents, adjunctive pharmacotherapies, electroconvulsive therapy, psychological interventions, family interventions, vocational rehabilitation, and assertive community treatment/intensive case management. Support for each recommendation is referenced to the previous PORT literature reviews, and the recommendations are rated according to the level of supporting evidence. The PORT Treatment Recommendations provide a basis for moving toward "evidence-based" practice for schizophrenia and identify both the strengths and limitations in our current knowledge base.

Linking primary care performance to outcomes of care.

Abstract: BACKGROUND Substantial research links many of the defining characteristics of primary care to important outcomes; yet little is known about the relative importance of each characteristic, and several characteristics have not been examined. These analyses evaluate the relationship between seven defining elements of primary care (accessibility, continuity, comprehensiveness, integration, clinical interaction, interpersonal treatment, and trust) and three outcomes (adherence to physician's advice, patient satisfaction, and improved health status). METHODS Data were derived from a cross-sectional observational study of adults employed by the Commonwealth of Massachusetts (N = 7204). All patients completed a validated questionnaire, the Primary Care Assessment Survey. Regression methods were used to examine the association between each primary care characteristic (11 summary scales measuring 7 elements of care) and each outcome. RESULTS Physicians' comprehensive ("whole person") knowledge of patients and patients' trust in their physician were the variables most strongly associated with adherence, and trust was the variable most strongly associated with patients' satisfaction with their physician. With other factors equal, adherence rates were 2.6 times higher among patients with whole-person knowledge scores in the 95th percentile compared with the 5th percentile (44.0% adherence vs 16.8% adherence, P < .001). The likelihood of complete satisfaction was 87.5% for those with 95th percentile trust scores compared with 0.4% for patients with 5th percentile trust scores (P < .001). The leading correlates of self-reported health improvements were integration of care, thoroughness of physical examinations, communication, comprehensive knowledge of patients, and trust (P < .001). CONCLUSIONS Patients' trust in their physician and physicians' knowledge of patients are leading correlates of three important outcomes of care. The results are noteworthy in the context of pervasive changes in our nation's health care system that are widely viewed as threatening to the quality of physician-patient relationships.

Health Literacy and the Risk of Hospital Admission

Abstract: Objective To determine the association between patient literacy and hospitalization. Design Prospective cohort study. Setting Urban public hospital. Patients A total of 979 emergency department patients who participated in the Literacy in Health Care study and had completed an intake interview and literacy testing with the Test of Functional Health Literacy in Adults were eligible for this study. Of these, 958 (97.8%) had an electronic medical record available for 1994 and 1995. Measurements and main results Hospital admissions to Grady Memorial Hospital during 1994 and 1995 were determined by the hospital information system. We used multivariate logistic regression to determine the independent association between inadequate functional health literacy and hospital admission. Patients with inadequate literacy were twice as likely as patients with adequate literacy to be hospitalized during 1994 and 1995 (31. 5% vs 14.9%, p Conclusions In this study population, patients with inadequate functional health literacy had an increased risk of hospital admission.

A Case-Control Study of HIV Seroconversion in Health Care Workers After Percutaneous Exposure

Abstract: A BSTRACT Background The average risk of human immunodeficiency virus (HIV) infection after percutaneous exposure to HIV-infected blood is 0.3 percent, but the factors that influence this risk are not well understood. Methods We conducted a case–control study of health care workers with occupational, percutaneous exposure to HIV-infected blood. The case patients were those who became seropositive after exposure to HIV, as reported by national surveillance systems in France, Italy, the United Kingdom, and the United States. The controls were health care workers in a prospective surveillance project who were exposed to HIV but did not seroconvert. Results Logistic-regression analysis based on 33 case patients and 665 controls showed that significant risk factors for seroconversion were deep injury (odds ratio 15; 95 percent confidence interval, 6.0 to 41), injury with a device that was visibly contaminated with the source patient’s blood (odds ratio 6.2; 95 percent confidence interval, 2.2 to 21), a procedure involving a needle placed in the source patient’s artery or vein (odds ratio 4.3; 95 percent confidence interval, 1.7 to 12), and exposure to a source patient who died of the acquired immunodeficiency syndrome within two months afterward (odds ratio 5.6; 95 percent confidence interval, 2.0 to 16). The case patients were significantly less likely than the controls to have taken zidovudine after the exposure (odds ratio 0.19; 95 percent confidence interval, 0.06 to 0.52). Conclusions The risk of HIV infection after percutaneous exposure increases with a larger volume of blood and, probably, a higher titer of HIV in the source patient’s blood. Postexposure prophylaxis with zidovudine appears to be protective. (N Engl J Med 1997;337:1485-90.)

An Epidemiologic Profile of Children With Special Health Care Needs

Abstract: Objective. To present an epidemiologic profile of children with special health care needs using a new definition of the population developed by the federal Maternal and Child Health Bureau. Methods. We operationalized the new definition using the recently released 1994 National Health Interview Survey on Disability. Estimates are based on 30 032 completed interviews for children Results. Eighteen percent of US children Conclusions. A substantial minority of US children were identified as having an existing special health care need using national survey data. Children with existing special health care needs are disproportionately poor and socially disadvantaged. Moreover, many of these children face significant barriers to health care.

Use of the UK General Practice Research Database for pharmacoepidemiology

Abstract: The last decade has seen a surge in the use of computerized health care data for pharmacoepidemiology. Of all European databases, the General Practice Research Database (GPRD) in the UK, has been the most widely used for pharmacoepidemiological research. Since 1994, this database has belonged to the UK Department of Health, and is maintained by the Office of National Statistics (ONS). Currently, around 1500 general practitioners with a population coverage in excess of 3 million, systematically provide their computerized medical data anonymously to ONS. Validation studies of the GPRD have documented the recording of medical data into general practitioners’ computers to be near to complete. The GPRD collects truly population-based data, has a size that makes it possible to follow-up large cohorts of users of specific drugs, and includes both outpatient and inpatient clinical information. The access to original medical records is excellent. Desirable improvements to the GPRD would be additional computerized information on certain variables and linkage to other health care databases. Most published studies to date have been in the area of drug safety. The General Practice Research Database has proved that valuable data can be collected in a general practice setting. The full potential of this rich computerized database has yet to come. This experience should serve to encourage others to develop similar population-based data in other countries.

Patterns of usual care for schizophrenia: Initial results from the Schizophrenia Patient Outcomes Research Team (PORT) Client Survey.

Abstract: To examine the conformance of current patterns of usual care for persons with schizophrenia to the Schizophrenia Patient Outcomes Research Team (PORT) Treatment Recommendations, the PORT surveyed a stratified random sample of 719 persons diagnosed with schizophrenia in two States. The types of treatment settings surveyed included acute inpatient programs and continuing outpatient programs in urban and rural locales. Using data from medical record reviews and patient interviews, the PORT assessed the conformance of current care with 12 of the Treatment Recommendations. The rates at which patients' treatment conformed to the recommendations were modest at best, generally below 50 percent. Conformance rates were higher for pharmacological than for psychosocial treatments and in rural areas than in urban ones. Rates of Treatment Recommendation conformance for minority patients were lower than those for Caucasians, and patterns of care varied between the two States. The findings indicate that current usual treatment practices likely fall substantially short of what would be recommended based on the best evidence on treatment efficacy. This disparity underscores the need for greater efforts to ensure that treatment research results are translated into practice.

Barriers and bridges to evidence based clinical practice

Abstract: This is the fourth in a series of eight articles analysing the gap between research and practice Series editors: Andrew Haines and Anna Donald Clinicians and healthcare planners who want to improve the quality and efficiency of healthcare services will find help in research evidence. This evidence is increasingly accessible through information services that combine high quality evidence with information technology. However, there are several barriers to the successful application of research evidence to health care. We discuss both the prospects for harnessing evidence to improve health care and the problems that readers—clinicians, planners, and patients—will need to overcome to enjoy the benefits of research(box). View this table: Problems in implementing evidence based medicine and possible solutions The aim of evidence based health care is to provide the means by which current best evidence from research can be judiciously and conscientiously applied in the prevention, detection, and care of health disorders.1 This aim is decidedly ambitious given how slowly important new treatments are disseminated into practice2–%4and how resistant practitioners are to withdrawing established treatments from practice even once their utility has been disproved.5 ### Summary points The barriers to the dissemination and timely application of research findings in the making of decisions about health care are complex and have been little studied. They include many factors beyond the control of the practitioner …

Health-Related Quality of Life in Patients Served by the Department of Veterans Affairs Results From the Veterans Health Study

Abstract: Background The Department of Veterans Affairs Health Care System (VA) is the largest integrated single payer system in the United States. To date, there has been no systematic measurement of health status in the VA. The Veterans Health Study has developed methods to assess patient-based health status in ambulatory populations. Objectives To describe the health status of veterans and examine the relationships between their health-related quality of life, age, comorbidity, and socioeconomic and service-connected disability status. Methods Participants in the Veterans Health Study, a 2-year longitudinal study, were recruited from a representative sample of patients receiving ambulatory care at 4 VA facilities in the New England region. The Veterans Health Study patients received questionnaires of health status, including the Medical Outcomes Study Short Form 36-Item Health Survey; and a health examination, clinical assessments, and medical history taking. Sixteen hundred sixty-seven patients for whom we conducted baseline assessments are described. Results The VA outpatients had poor health status scores across all measures of the Medical Outcomes Study Short Form 36-Item Health Survey compared with scores in non-VA populations (at least 50% of 1 SD worse). Striking differences also were found with the sample stratified by age group (20-49 years, 50-64 years, and 65-90 years). For 7 of the 8 scales (role limitations due to physical problems, bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, and mental health), scores were considerably lower among the younger patients; for the eighth scale (physical function), scores of the young veterans (aged 20-49 years) were almost comparable with the levels in the old veterans (>65 years). The mental health scores of young veterans were substantially worse than all other age groups (P Conclusions The VA outpatients have substantially worse health status than non-VA populations. Mental health differences between the young and old veterans who use the VA health care system are sharply contrasting; the young veterans are sicker, suggesting substantially higher resource needs. Mental health differences may explain much of the worse health-related quality of life in young veterans. As health care systems continue to undergo a radical transformation, the Department of Veterans Affairs should focus on the provision of mental health services for its younger veteran.

Mortality as an indicator of economic success and failure.

Abstract: Quality of life depends on various physical and social conditions such as the epidemiological environment in which a person lives. The availability of health care and the nature of medical insurance--public as well as private--are among the important influences on life and death. So are other social services including basic education and the orderliness of urban living and the access to modern medical knowledge in rural communities. The statistics on mortality draw our attention to all these policy issues. Mortality information can throw light also on the nature of social inequalities including gender bias and racial disparities. (EXCERPT)

The POSNA pediatric musculoskeletal functional health questionnaire: report on reliability, validity, and sensitivity to change. Pediatric Outcomes Instrument Development Group. Pediatric Orthopaedic Society of North America.

Abstract: The goal of orthopaedic interventions is to improve the functional health of patients, particularly physical function. The American Academy of Orthopaedic Surgeons and the Pediatric Orthopaedic Society of North America (POSNA) commissioned a work group to construct functional health outcomes scales for children and adolescents, focusing on musculoskeletal health. The work group developed scales assessing upper extremity function, transfers and mobility, physical function and sports, comfort (pain free), happiness and satisfaction, and expectations for treatment. Parent and adolescent self-report forms were developed and tested on 470 subjects aged 2-18 years. The POSNA scales demonstrated good reliability, construct validity, sensitivity to change over a 9-month period, and ability to outperform a standard instrument, the Child Health Questionnaire physical functioning scale. They were useful for a wide variety of ages and diagnoses. They appear to be ideally suited for orthopaedic surgeons to assess the functional health and efficacy of treatment of their patients at baseline and follow-up.

Health care contingent valuation studies : a review and classification of the literature

Abstract: Purpose: The contingent valuation method (CVM) is a survey-based approach for eliciting consumer's monetary valuations for programme benefits for use in cost-benefit analysis (CBA). We used the conceptual framework of O'Brien and Gafni (1996) to classify and critically appraise health care CVM studies. Methods: Search of computerized health care and economic citation databases (e.g. MEDLINE, ECONLIT) and manual search for papers published between 1984–1996 reporting primary data valuing health programme benefits in monetary units by CVM using willingness-to-pay (WTP) or accept (WTA). We classified studies using both empirical (i.e. who was surveyed and how) and conceptual criteria (i.e. which measure of consumer utility was measured and why). Results: 48 CVM studies were retrieved; the majority (42) undertook money valuation in the context of cost benefit analysis (CBA), with the remainder being pricing/demand studies. Among the 42 CBA studies, the consumer utility being measured (i.e. compensating (CV) vs. equivalent variation (EV) was explicitly stated in only three (7%) studies). WTP was measured in 95% of studies and WTA in 5%. By cross-tabulation, 42 (91%) studies were designed as WTP/CV, two (4%) were WTP/EV, two (4%) were WTA/CV and no studies used WTA/EV. Most studies were administered by mail (52%) with 38% being in-person interviews. Value elicitation techniques included open-ended questions (38%), payment cards (19%) discrete choice questions (26%) or bidding games (29%). Some form of construct validation tests, particularly associations between WTP and income, were done in 21 studies (50%). Conclusions: (i) The number of health care CVM studies is growing rapidly and the majority are done in the context of CBA; (ii) there is wide variation among health care CVM studies in terms of the types of questions being posed and the elicitation formats being used; (iii) classification and appraisal of the literature is difficult because reporting of methods and their relationship with the conceptual framework of CBA is poor; (iii) the applicability to health care of the CVM guidelines issued by the National Oceanic and Atmospheric Administration (NOAA) panel for environmental economics is unclear. © 1998 John Wiley & Sons, Ltd.

Treating Major Depression in Primary Care Practice: An Update of the Agency for Health Care Policy and Research Practice Guidelines

Abstract: The Depression Guideline Panel of the Agency for Health Care Policy and Research in 1993 published recommendations for treating major depression in primary care practice that were often based on studies of tertiary care psychiatric patients. We reviewed reports of randomized controlled trials in primary care settings published between 1992 and 1998. This evidence indicates that both antidepressant pharmacotherapy and time-limited depression-targeted psychotherapies are efficacious when transferred from psychiatric to primary care settings. In most cases, the choice between these treatments should depend on patient preference. Studies to date suggest that improving treatment of depression in primary care requires properly organized treatment programs, regular patient follow-up, monitoring of treatment adherence, and a prominent role for the mental health specialist as educator, consultant, and clinician for the more severely ill. Future research should focus on how guidelines are best implemented in routine practice, since conventional dissemination strategies have little impact.

Randomised trial of impact of model of integrated care and case management for older people living in the community

Abstract: Objective: To evaluate the impact of a programme of integrated social and medical care among frail elderly people living in the community. Design: Randomised study with 1 year follow up. Setting: Town in northern Italy (Rovereto). Subjects: 200 older people already receiving conventional community care services. Intervention: Random allocation to an intervention group receiving integrated social and medical care and case management or to a control group receiving conventional care. Main outcome measures: Admission to an institution, use and costs of health services, variations in functional status. Results: Survival analysis showed that admission to hospital or nursing home in the intervention group occurred later and was less common than in controls (hazard ratio 0.69; 95% confidence interval 0.53 to 0.91). Health services were used to the same extent, but control subjects received more frequent home visits by general practitioners. In the intervention group the estimated financial savings were in the order of £1125 ($1800) per year of follow up. The intervention group had improved physical function (activities of daily living score improved by 5.1% v 13.0% loss in controls; P Conclusion: Integrated social and medical care with case management programmes may provide a cost effective approach to reduce admission to institutions and functional decline in older people living in the community. Key messages Responsibility for management of care of elderly people living in the community is poorly defined Integration of medical and social services together with care management programmes would improve such care in the community In a comparison of this option with a traditional and fragmented model of community care the integrated care approach reduced admission to institutions and functional decline in frail elderly people living in the community and also reduced costs
