Associations between the use of do-not-resuscitate orders and length of stay in patients with stroke

OBJECTIVES

The study sought to describe the association between do-not-resuscitate (DNR) orders and length of hospital stay (LOS), and how the association varies according to in-hospital mortality, timing of the DNR order, and admission severity of illness.

METHODS

The authors conducted a retrospective cohort analysis involving standardized review of patients' medical records. The study was performed at 30 acute care hospitals in a large metropolitan area. The authors studied the data of 13,337 consecutive patients with a primary diagnosis of stroke discharged in 1991 through 1994.

RESULTS

Do-not-resuscitate orders were written for 22% (n = 2,898) of the sample. In all patients, mean LOS was longer in patients with DNR orders than in patients without orders (12.0 versus 9.5 days; P < 0.001). A series of Cox regression analyses were performed to adjust LOS for admission severity of illness and other covariates. In analyses of patients discharged alive (n = 12,011), LOS was similar in patients with DNR orders written on days 1 to 2 compared with patients without DNR orders. However, LOS was longer in patients with DNR orders written on days 3 to 7 (Hazard Ratio [HR], 1.59; 95% CI, 1.43-1.77) and on day 8 or later (HR, 2.72; 95% CI, 2.34-3.16). In analyses of patients who died (n = 1,326), LOS was shorter for patients with DNR orders written on days 1 and 2 (HR, 0.59; 95% CI, 0.49-0.71) than for patients without DNR orders but was longer among patients with DNR orders written on day 8 or later (HR, 2.58; 95% CI, 2.06-3.22). In analyses stratified by admission severity, the relative effect of a DNR order tended to be less in patients with higher severity.

CONCLUSIONS

The relationship between DNR orders and LOS is complex and varies according to in-hospital mortality, the timing of the DNR order, and admission severity of illness. These findings highlight the importance of explicitly accounting for such factors in studies evaluating the implications of DNR orders on the costs of hospital care.

Prevention and primary care research for children. The need for evidence to precede "evidence-based"

Medical care in the United States continues to face tremendous financial pressures. Public and private health policy claim to encourage primary care and preventive services, but also discourage services that have not been demonstrated to be effective and/or cost-effective. This article suggests a model to illustrate the conceptual relationship between traditional American medical care and "evidenced-based" medicine. It further examines how the lack of an adequate research base makes a move to purely evidence-based care premature for primary care and prevention services. The paper defines a new conceptual statistic, the uncertainty index, as the proportion of non-refuted current practice that is also not corroborated by research evidence. The greater the uncertainty index, the less appropriate is a clinical model restricted to evidence-based care. Specific theoretical barriers to outcomes research in prevention are discussed and simple criteria to determine the desirable components of care are suggested. The need for theoretical and empirical research into primary care and prevention, especially for children, is emphasized. Care that is of low risk, not of extremely high cost, and that is generally believed useful by the community of practitioners is particularly desirable in the absence of data refuting its value.

Aging, health risks, and cumulative disability

BACKGROUND

Persons with lower health risks tend to live longer than those with higher health risks, but there has been concern that greater longevity may bring with it greater disability. We performed a longitudinal study to determine whether persons with lower potentially modifiable health risks have more or less cumulative disability.

METHODS

We studied 1741 university alumni who were surveyed first in 1962 (average age, 43 years) and then annually starting in 1986. Strata of high, moderate, and low risk were defined on the basis of smoking, body-mass index, and exercise patterns. Cumulative disability was determined with a health-assessment questionnaire and scored on a scale of 0 to 3. Cumulative disability from 1986 to 1994 (average age in 1994, 75 years) or death was the measure of lifetime disability.

RESULTS

Persons with high health risks in 1962 or 1986 had twice the cumulative disability of those with low health risks (disability index, 1.02 vs. 0.49; P<0.001). The results were consistent among survivors, subjects who died, men, and women and for both the last year and the last two years of observation. The onset of disability was postponed by more than five years in the low-risk group as compared with the high-risk group. The disability index for the low-risk subjects who died was half that for the high-risk subjects in the last one or two years of observation.

CONCLUSIONS

Smoking, body-mass index, and exercise patterns in midlife and late adulthood are predictors of subsequent disability. Not only do persons with better health habits survive longer, but in such persons, disability is postponed and compressed into fewer years at the end of life.

Overview of otolaryngic allergy management. An eclectic and cost-effective approach

Ear, nose, and throat allergic assessment plays an integral role in the evaluation and care of approximately 25% of patients seen in a general otolaryngology practice. With the advances in health care delivery and the influence of managed care organizations, physicians are asked to render cost-effective evaluation and management of their patients. This article examines the economic issues and historical data regarding the work-up of patients with suspected allergic problems. Relative cost-benefits of different modalities of treatments, including avoidance techniques, pharmacotherapy, and immunotherapy, are discussed.

On the success, cost and efficiency of modern medicine: an international comparison

OBJECTIVE

To study the success and cost of modern medicine in industrialized, rich countries from 1980 to 1990.

DESIGN

Cost per capita and per cent of gross domestic product (GDP) spent on health was related to: (i) mortality in six diseases amenable to treatment by modern medicine; (ii) the sum of those six diseases (avoidable disease); (iii) death due to other, unavoidable diseases; (iv) maternal and infant mortality; (v) life expectancy at birth; (vi) renal dialysis and transplantation rates. Efficiency was studied by comparing a country's avoidable mortality rates multiplied by expenses, to the mean for all countries.

RESULTS

During the 10 years, avoidable death rate decreased 38% but unavoidable death rate only 10%. Life expectancy increased 3%. Cost per capita increased 107% but health expenditures, as per cent of GDP only 10%. There was a reasonable correlation between expenses and avoidable mortality but none between expenses and unavoidable death rate. In 1990 avoidable mortality was lowest in Canada, and highest in Japan. Cost was lowest in New Zealand, and highest in the USA. The efficiency index was highest for Australia, and lowest in the USA.

CONCLUSION

Modern medicine as we have studied it is successful. Avoidable death rate shows a steep uninterrupted decline over the last 50 years while unavoidable death rate shows only small decreases. Cost as per cent of GDP has increased only moderately. There is a correlation between expenses and mortality from avoidable but not from unavoidable diseases, and a large variation in efficiency.

Clinical and cost outcomes of multifactorial, cardiovascular risk management interventions in worksites: a comprehensive review and analysis

This paper is a critical review of the clinical and cost outcome evaluation studies of multifactorial, comprehensive, cardiovascular risk management programs in worksites. A comprehensive international literature search conducted under the auspices of the National Heart, Lung and Blood Institute identified 17 articles based on 12 studies that examined the clinical outcomes of multifactorial, comprehensive programs. These articles were identified through MEDLINE, manual searches of recent journals, and through direct inquiries to worksite health promotion researchers. All studies were conducted between 1978 and 1995, with 1978 being the date of the first citation of a methodologically rigorous evaluation. Of the 12 research studies, only 8 utilized the worksite as both the unit of assignment and as the unit of analysis. None of the studies analyzed adequately for cost effectiveness. Given this limitation, this review briefly considers the relevant worksite research that has demonstrated cost outcomes. Worksite-based, multifactorial cardiovascular intervention programs reviewed for this article varied widely in the comprehensiveness, intensity, and duration of both the interventions and evaluations. Results from randomized trials suggest that providing opportunities for individualized, cardiovascular risk reduction counseling for high-risk employees within the context of comprehensive programming may be the critical component of an effective worksite intervention. Despite the many limitations of the current methodologies of the 12 studies, the majority of the research to date indicates the following: (1) favorable clinical and cost outcomes; (2) that more recent and more rigorously designed research tends to support rather than refute earlier and less rigorously designed studies; and (3) that rather than interpreting the methodological flaws and diversity as inherently negative, one may consider it as indicative of a robust phenomena evident in many types of worksites, with diverse employees, differing interventions, and varying degrees of methodological sophistication. Results of these studies reviewed provide both cautious optimism about the effectiveness of these worksite programs and insights regarding the essential components and characteristics of successful programs.

Quality and outcomes management in gastroenterology

The delivery of medical care is undeniably changing. Resources are becoming increasingly scarce, and the progressive rise of health care expenditures needs to be restrained. Although the field of outcomes assessment is not well understood, it is increasingly being applied to the practice of medicine. The underlying goal of outcomes management should be to improve quality by identifying the most efficient use of finite resources and integrating these into practice guidelines. Although reduction of health care costs is important, it should be a secondary goal. Providers of health care must take an active role in outcomes research and management both in understanding and in implementing these techniques in medical practice. In doing so, it is essential that physicians maintain the proper emphasis on quality patient care.

Promoting group psychotherapy in managed care: basic economic principles for the clinical practitioner

Knowledge of the basic economic factors underlying managed mental health care directly impacts the clinical practitioners' ability to make constructive changes in the system. To aid understanding this article introduces the managed care marketplace model, the interactive relationship between medical necessity and patient co-payment, and demand management economics. The author encourages practitioners to develop strategies to overcome specific economic obstacles that prevent the promotion of group psychotherapy.

The cost-effectiveness of intensive therapy for diabetes mellitus

Although persons with diabetes constitute only 3.1% of the US population, costs for their care account for 11.9% of total US health care expenditures. Approximately half of the expenditures for medical care for diabetes are for treatment of the metabolic condition and half for the treatment of chronic complications. Intensive therapy for persons with diabetes uses more resources and is more expensive than conventional therapy. On the other hand, intensive therapy is associated with a lower incidence of costly chronic complications. Formal economic analyses have demonstrated that intensive therapy is cost-effective for the treatment of diabetes. In IDDM, intensive therapy costs approximately $20,000 per QALY gained; in NIDDM, it costs approximately $16,000 per QALY gained. From an economic perspective, intensive therapy for persons with diabetes compares favorably with pharmacologic therapy for high-risk individuals with hypertension and hypercholesterolemia. Health policy should foster the use of such therapy for persons with diabetes mellitus.

Managed care. What is its impact on nursing education and practice?

Market forces present the nursing profession with an urgency to prepare gerontological nurses to assume significant roles in the managed care industry. An understanding of the current managed care environment underscores the need for training. Nurses require a "managed care" skill-set encompassing a firm grasp of the organization, financing, delivery, and policy implications of managed care as well as advanced practice clinical skills and a sound business orientation. The importance of the consumer as a significant player in managed care is highlighted.

Does fluoridation reduce the use of dental services among adults?

OBJECTIVES

The authors determine whether prevention influences the use of health services. Fluoridation's effect on restorative dental demand among 972 Washington state employees and spouses, aged 20 to 34 years, in two fluoridated communities and a nonfluoridated community was examined.

METHODS

At baseline, adults were interviewed by telephone, and oral assessments were conducted to measure personal characteristics, lifetime exposure to fluoridated water, oral disease, and the quality of restorations. Adults were followed for 2 years to measure dental demand from dental claims. Each adult's baseline and claims data were linked with provider and practice variables collected from the dentist who provided treatment.

RESULTS

Relative to adults with no lifetime exposure to fluoridated water, adults drinking fluoridated water for half or more of their lives had less disease at baseline and a lower but nonsignificant probability of receiving a restoration in the follow-up period. In the 2-year follow-up period, however, more than half of the restorations were performed to replace fillings of satisfactory or ideal quality at baseline. When only teeth with decay and unsatisfactory fillings at baseline were considered, adults with high fluoridation exposure had a lower probability of receiving a restoration than adults with no exposure. Market effects also were detected in demand equations; relative to adults in the nonfluoridated community, adults residing in the fluoridated community with a large dentist supply received a greater number of restorations, suggesting potential supplier-induced demand from less disease and fewer patients.

CONCLUSIONS

Among adults aged 20 to 34 years with private dental insurance, fluoridation reduces oral disease but may or may not reduce use of restorative services, depending on dentists' clinical decisions.

Take Heart II: replication of a worksite health promotion trial

The purpose of this study was to evaluate the effects of a revised worksite health promotion program that featured an employee steering committee/menu approach to intervention. The "Take Heart II" program was evaluated using a quasi-experimental matched-pair design with worksite as the unit of analysis. Experimental and control worksites did not differ on baseline organizational or employee demographic variables or on baseline levels of dependent variables. Outcome and process results revealed consistent, but modest effects favoring intervention worksites on most measures. Cross-sectional analyses generally failed to produce statistically significant intervention effects, but cohort analyses revealed significant beneficial effects of the Take Heart II intervention on eating patterns, behavior change attempts, and perceived social support. Neither analysis detected a beneficial effect of intervention on cholesterol levels.

Putting prevention into practice

One of the three broad goals of Healthy People 2000 is that preventive services will be available to all Americans. Although there is professional agreement on the merits of prevention, there are challenges related to implementing preventive health care. Six of these challenges are confusion in terminology, issues related to nursing autonomy and initiative, differing conceptual frameworks, complexity of coordination within a delivery system that does not reward preventive services, prevalent cultural beliefs, and lack of uniform recommendations regarding prevention. The Put Prevention into Practice (PPIP) program is a national strategy to address those challenges. The American Nurses Association and the American Academy of Nurse Practitioners contributed to the development of the PPIP program. These organizations are actively disseminating the information through train-the-trainer methodology and other educational programs that will prepare nurses to improve the health of the population through the provision of preventive health services.

Advanced practice nurses in integrated health care systems

Changes in the health care delivery system are discussed with a view to those affecting the role and use of advanced practice nurses and particularly nurse practitioners who provide primary and reproductive care to women. Nurse practitioners are particularly well suited to function within integrated systems. They accomplish cost-containment strategies because of lower salaries or fees, fewer invasive procedures, greater compliance by patients, and increased nonpharmacologic treatments. They collaborate with all providers of primary care and enhance communication with patients. They develop clinical pathways for professionals and for patients and their families and support the use of guidelines and protocols to enhance standards of practice. It is suggested that women will become powerful consumers and that nurse practitioners are especially versed, not only in providing routine screening and episodic care, but also in teaching self-care, providing developmental and emotional support, and increasing compliance for health promotion and disease prevention. A high demand exists for education as an advanced practice nurse. Although many educational programs are moving to the master's degree, standardized educational levels are urged as a means for professionals and consumers to better understand advanced practice nursing roles. The need for nurse practitioners in the primary care market-place is demonstrated, but the system is in a state of flux, and the roles may not be used appropriately. Nurse practitioners should help to define new jobs and be assertive in negotiating for positions.

The rhetorics and realities of community health care: the limits of countervailing powers to meet the health care needs of the twenty-first century

As the paradox of medical success leaves behind more chronicity, policy makers around the world increasingly focus on community-based programs both to address chronic health problems and to prevent major disorders. This essay presents my comparative sociological framework of ideal-type models for understanding the countervailing powers that underlie and shape different kinds of heath care systems and their limitations in addressing the health care needs of the twenty-first century. In this context, I then analyze the revival of community health care rhetoric in the United States and compare it to the realities in which it operates. The realities of institutional power, fragmentation in funding, illness as a private condition and health care as a private good, the lack of societal commitment, competition, and the waning of community cohesion all suggest that communal democracy will be difficult to achieve. Current successes require further investigation. Examples from abroad suggest, ironically, that community health care develops best if the state and health professionals make a deep commitment to it, against their own immediate interests but for their enlightened self-interest.

Medicare revenue in large medical groups

The aged are the heaviest users of physician services. A ageing population and escalation in medical costs have pressured Medicare budgets, which have increased fastest in Part B physician reimbursement. Policy responses include adoption of the Resource Based Relative Value Scale (RBRVS) for physician payment. This paper considers receipt of Medicare revenues by large medical groups and expectations of how groups will fare under RBRVS. In a 73-percent sample of U.S. large group practices, Medicare coverage accounted for one-fourth of clients, Medicare-related revenues for slightly more than one-fourth of revenues, suggesting a slightly higher revenue intensity for Medicare clients, but showing no evidence of truly disproportionate revenues from Medicare users. Medicare shares of revenues are explained by factors related to Medicare clientele and geriatric service provision. Overly-strict Medicare assignment policy may control costs by limiting access to needed care, rather than by limiting overpayments to physicians. Expectations as to how groups will fare under RBRVS are not found to be related to reliance on Medicare, rather to group auspices and ability to contain costs under Medicare payment. The findings are important not only to physician payment under RBRVS but also under health care reform.

Decreasing disability in the 21st century: the future effects of controlling six fatal and nonfatal conditions

OBJECTIVES

This study assessed the effects of reducing fatal and nonfatal health conditions on the number of functionally limited older Americans in the coming decades.

METHODS

Data from the 1990 census and the Longitudinal Study of Aging were used to project the number of functionally limited older Americans from 2001 to 2049, assuming 1% biennial reductions in five conditions that shorten life expectancy (coronary artery disease, stroke, cancer, diabetes, and confusion) and one condition that decreases functional ability (arthritis).

RESULTS

Decreasing the prevalence of arthritis by 1% every 2 years would lead to a much greater reduction in functional limitation between 2001 and 2049 (4 million person-years) than would decreasing any of the other conditions by the same amount. Decreases in two fatal conditions (cancer and coronary artery disease) would lead to increases in functional limitation (0.9 and 0.1 million person-years, respectively).

CONCLUSIONS

Advances against common nonfatal disabling conditions would be more effective than advances against fatal conditions in blunting the large increase in the functionally limited older population anticipated in the 21st century.

The ecology of work and health: research and policy directions for the promotion of employee health

This article identifies new research and policy directions for the field of worksite health in the context of the changing American workplace. These directions are viewed from an ecological perspective on worksite health and are organized around three major themes: (1) the joint influence of physical and social environmental factors on occupational health, (2) the effects of nonoccupational settings (e.g., households, the health care system) on employee well-being and the implications of recent changes in these settings for worksite health programs, and (3) methodological issues in the design and evaluation of worksite health programs. Developments in these areas suggest that the field of worksite health may be undergoing a fundamental paradigm shift away from individually oriented wellness programs (provided at the worksite and aimed primarily at changing employees' health behavior) and toward broader formulations emphasizing the joint impact of the physical and social environment at work, job-person fit, and work policies on employee well-being.

Preserving the patient referral process in the managed care environment

Referrals are a central component of the American health care system, defining the relationship among generalists, patients, and specialists. The dynamics of the referral process as they existed in a fee-for-service medical environment will evolve under managed care, but retain the basic "Try-out" approach of the generalist and "Rule-out" approach of the specialist. A managed care, contract-based health care system alters some of the assumptions on which the referral relationship has been structured. A four-step approach to assuring quality interactions among patient, generalist, and specialist within the managed care environment is described, including: (1) engage; (2) anticipate; (3) feedback; and (4) reassess. When the referral process is structured as suggested, it can be evaluated for quality and efficacy. Armed with mutual respect and understanding, the forces that polarized specialist and generalist care in the 1980s can be redirected to enhancing patient care in the 1990s.

A guide for planning community-oriented health care: the health sector resource allocation model

The objective of this study was to demonstrate the value of a planning model for the design and evaluation of community health services. The health status of Washtenaw County, Michigan was modeled. Data were obtained from the Michigan Department of Public Health, Medstat Systems, and the medical literature for 32 diseases or conditions, representing approximately 85% of causes of death and 56% of medical payments (excluding medication costs). An expanded life-table approach was used for 16 age-and sex-matched cohorts exposed to a disease attack rate, access-to-care rate, case fatality rate, morbidity, and costs. Rates can be modified to reflect changes due to treatment, secular trends, or prevention programs. Two alternative delivery methods were considered to show the potential impact of reducing cardiovascular deaths (worksite initiative), or increasing utilization of services (lay health promotion) on county health status and costs over time. Deaths, bed days, and annual medical payments were the main outcome measurements. Cardiovascular and cancer conditions are and will be the primary causes of death in this population. The most important causes of bed days are musculoskeletal conditions, chronic obstructive pulmonary disease, accidents, strokes, and depression. The major health-care payments are for angina pectoris and/or other cardiac conditions, musculoskeletal conditions, accidents, prenatal care, and/or childbirth, and depression. The two alternative scenarios illustrate how reductions in mortality are not necessarily equated with similar improvements in morbidity or costs. This model presents an overview of the current and projected health status of a community. With such a planning tool, a community can better understand the impact of potential prevention or intervention programs, and help design its health-care system within the constraints of available resources.

The impact of the transcendental meditation program on government payments to physicians in Quebec

PURPOSE

This study evaluated whether governmental medical payments in Quebec were affected by the Transcendental Meditation (TM) technique.

DESIGN

This retrospective study used a pre- and postintervention design in which government payments for physicians' services were reviewed for 3 years before and up to 7 years after subjects started the technique. Payment data were adjusted for aging and year-specific variation (including inflation) using normative data. No separate control group was used; thus it is impossible to determine whether the changes were caused by the TM program or some other factor.

SUBJECTS

A volunteer group of 677 provincial health insurance enrollees was evaluated. The subjects had chosen to practice the TM technique before they were selected to enter the study. The subjects (348 men, 329 women) had diverse occupations. Their average age was 38 years and ranged from 18 to 71 years at the start of the TM program.

INTERVENTION

The TM technique of Maharishi Mahesh Yogi is a standardized procedure practiced for 15 to 20 minutes twice daily while sitting comfortably with eyes closed.

SETTING

Province of Quebec, Canada.

RESULTS

During the 3 years before starting the TM program, the adjusted payments to physicians for treating the subjects did not change significantly. After beginning TM practice, subjects' adjusted expenses declined significantly. The several methods used to assess the rate of decline showed estimates ranging from 5% to 7% annually.

CONCLUSIONS

The results suggests that the TM technique reduces government payments to physicians. However, because of the sampling method used, the generalizability of these results to wider populations could not be evaluated.

Principles of Cancer Screening

Early detection of cancer, prior to its clinical manifestations, appears to be a worthwhile and desirable goal. Yet, the concept and acceptance of cancer screening remain controversial and often confusing. While the benefits of screening are obvious to those whose screening tests have resulted in successful interventions, attention also needs to be given to the risks, economic costs, and psychological effects of screening procedures. Specific governing principles that define the cancers to be screened, the appropriate screening test, and the measurement of outcomes should be established in order for a screening program to be deemed worthwhile. A beneficial screening strategy detects cancer prior to its systemic spread, alters the natural history of the disease, and defers the time of death.

A randomised controlled trial of stress reduction for hypertension in older African Americans

We tested the short-term efficacy and feasibility of two stress education approaches toe the treatment of mild hypertension in older African Americans. This was a randomized, controlled, single-blind trial with 3 months of follow-up in primary care, inner-city health center. Of 213 African American men and women screened, 127 individuals (aged 55 to 85 years with initial diastolic pressure of 90 to 109 mm Hg, systolic pressure of < or = 189 mm Hg, and final baseline blood pressure of < or = 179/104 mm Hg) were selected. Of these, 16 did not complete follow-up blood pressure measurements. Mental and physical stress reduction approaches (Transcendental Meditation and progressive muscle relaxation) were compared with a lifestyle modification education control program and with each other. The primary outcome measures were changes in clinic diastolic and systolic pressures from baseline to final follow-up, measured by blinded observers. The secondary measures were linear blood pressure trends, changes in home blood pressure, and intervention compliance. Adjusted for significant baseline differences and compared with control, Transcendental Meditation reduced systolic pressure by 10.7 mm Hg (P < .0003) and diastolic pressure by 6.4 mm Hg (P <.00005). Progressive muscle relaxation lowered systolic pressure by 4.7 mm Hg (P = 0054) and diastolic pressure by 3.3 mm Hg (P <.02). The reductions in the Transcendental Meditation group were significantly greater than in the progressive muscle relaxation group for both systolic blood pressure (P = .02) and diastolic blood pressure (P = .03). Linear trend analysis confirmed these patterns.(ABSTRACT TRUNCATED AT 250 WORDS)

Prevention of cardiovascular disease: from biomedical research to health policy

Cardiovascular diseases (CVD) are the leading cause of premature death and disability in the developed world. Broad consensus exists on CVD preventability through reduction of their risk factors at both the individual and population level. The latter kind of intervention implies involvement of policy-making institutions, owing to the manifold implications (agriculture, industry, environment) of such programmes. They have to be developed through three phases in succession: observational studies; intervention trials; public health action programmes. The implementation of the latter can only result from merging of biomedicine and politics and must rest on sound scientific-ethical bases. Other important issues are cost effectiveness, resort to mass media, transfer to other communities, funding and institutionalization. As a practical example of development and implementation of a public health programme, the experience of the ATS-Sardegna Campaign is briefly described.

Use of medical care after a community-based health promotion program: a quasi-experimental study

PURPOSE

To assess the effects of health promotion on the use of medical care services in a community setting.

DESIGN

Quasi-experimental, multiple time points, case-comparison group.

SETTING

Community health center in Ottawa, Canada.

SAMPLE

520 volunteer participants in a health promotion program and 932 matched comparison subjects.

INTERVENTION

The health promotion program consisted of a weekend workshop on health behaviors, lifestyle assessment, and identification of weekly goals for change. This was followed by 18 months of support (5 group sessions, weekly telephone calls, and optional individual sessions).

MEASUREMENT

Computerized data on health care use 6 months before, 18 months during, and 6 months after the program were obtained from Ontario's universal Health Insurance Plan (OHIP). These data were used to determine the number and system costs of visits made by participants and comparisons.

RESULTS

When controlling for baseline differences through analysis of covariance, program participants were found to have higher costs and more visits for ambulatory care during the first year (p < .01) and second year (p < .05) of follow-up. Participants used significantly more diagnostic services than comparisons during both years of follow-up. Participants were also more likely to use more counseling and psychotherapy services in year 1 (relative risk, 1.53; 95% confidence interval, 1.28, 1.81) and year 2 (relative risk, 1.57; 95% confidence interval, 1.31, 1.89). No differences were found between participant and comparison groups in visits for medical consultations and assessments or preventive services.

CONCLUSION

No evidence shows that this health promotion program reduced use in this population over the 2-year follow-up period.

A randomised trial of compassionate care for the homeless in an emergency department

Homeless adults often visit emergency departments and often leave dissatisfied. We tested whether compassionate care, by improving patient satisfaction, can alter subsequent use of emergency services. We identified 133 consecutive homeless adults visiting one inner-city emergency department who were not acutely psychotic, extremely intoxicated, unable to speak English, or medically unstable. Half were randomly assigned to receive compassionate contact from trained volunteers. All patients otherwise had usual care and were followed for repeat visits to emergency departments. We found that rates of use were high, with patients making an average of seven visits a year (0.60 per month). More than a third of all patients made two or more visits within two days of each other. The average number of visits per month after intervention was significantly lower for patients who received compassionate care (0.43 vs 0.65, p = 0.018). Analyses adjusting for each patient's previous rate of use confirmed that compassionate care led to a one third reduction in the number of return visits within one month (95% CI 14 to 40%). Compassionate management of selected homeless adults decreases repeat visits to the emergency department. One explanation is that patients tend to return frequently until they are satisfied with their treatment.

Rethinking medicine: improving health outcomes with cost-effective psychosocial interventions

Thoughts, feelings, and moods can have a significant effect on the onset of some diseases, the course of many, and the management of nearly all. Many visits to the doctor are occasioned by psychosocial distress. Even in those patients with organic medical disorders, functional health status is strongly influenced by mood, coping skills, and social support, yet the predominant approach in medicine is to treat people with physical and chemical treatments that neglect the mental, emotional, and behavioral dimensions of illness. This critical mismatch between the psychosocial health needs of people and the usual medical response leads to frustration, ineffectiveness, and wasted health care resources. There is emerging evidence that empowering patients and addressing their psychosocial needs can be health and cost effective. By helping patients manage not just their disease but also common underlying needs for psychosocial support, coping skills, and sense of control, health outcomes can be significantly improved in a cost-effective manner. Rather than targeting specific diseases or behavioral risk factors, these psychosocial interventions may operate by influencing underlying, shared determinants of health such as attitudes, beliefs, and moods that predispose toward health in general. Although the health care system cannot be expected to address all the psychosocial needs of people, clinical interventions can be brought into better alignment with the emerging evidence on shared psychosocial determinants of health by providing services that address psychosocial needs and improve adaptation to illness.

Changes in health care: challenges for information system design

It is widely recognized that the systematic availability of medical care services is a vital component of the social network. Although particular political, cultural and economic factors lead to different strategic approaches in different countries, all are faced with balancing resource allocation against the perceived desirability of the results. In many countries the social urgency to address this issue has reached a critical status. All of the current changes and challenges in health care delivery are to a large extent being driven by these considerations. Information systems consisting of telecommunication and computing technologies will play a key role in supporting emerging delivery systems. The purpose of this brief paper is to identify the major themes within this complex network of considerations and to serve perhaps as a road map in on-going system design and evaluation efforts.

Self-management, autonomy, and quality of life in asthma. Population Medicine Group 91C

STUDY OBJECTIVE

Asthma management guidelines emphasize increased autonomy for asthmatics through patient education and patient-initiated action plans. The aim of this study was to examine autonomy, as reflected in the preferences of asthmatic subjects for decision making and their preferences for information seeking. The results were related to quality of life in asthma.

SUBJECTS

One hundred twenty-three adults with asthma.

DESIGN

Questionnaire-based cross-sectional analytic survey.

SETTING

Eighty-five subjects were recruited from community pharmacies at the point of sale of albuterol inhalers for asthma and compared with 38 subjects recently hospitalized for acute severe asthma.

MEASUREMENTS

Asthma-related quality of life, autonomy preferences questionnaire.

RESULTS

The subjects in both groups had a mild-to-moderate quality of life impairment in all domains that was greater in the posthospitalization group (p < 0.05). Both groups expressed strong preferences for information concerning their condition (92se 0.8, 91se 1.1, out of a possible 100). Subjects did not prefer to make decisions alone about the management of asthma exacerbations (51.0se 1.2, 52.5 se2.0, out of a possible 100). As the severity of the asthma exacerbation increased, the desire to make decisions decreased (p < 0.05). Older subjects expressed less desire for decision making than younger subjects. Self-management autonomy was not correlated with quality of life in asthma.

CONCLUSIONS

We conclude that while asthmatics have strong desires to be informed about their illness, they do not wish to be the prime decision makers during an exacerbation. These findings have implications for the success of self-management programs and action plans.

Excess catecholamines and the metabolic syndrome: should central imidazoline receptors be a therapeutic target?

A sympathetic overactivity plays a major role in the pathogenesis of cardiovascular diseases in Westernized affluent societies. Of importance is an increased caloric intake and psychosocial stress which are associated with a raised central sympathetic outflow and unfavourable changes in metabolic parameters. Normalization of central sympathetic outflow could thus be a major therapeutic target. The newly developed antihypertensive drugs moxonidine and rilmenidine reduce the excitatory activity of neurons of the rostral ventrolateral medulla (RVLM) via binding to imidazoline receptors. Using radio telemetry, it is shown that, in contrast to the first generation centrally acting drug clonidine, moxonidine did not result in rebound of blood pressure after drug withdrawal in rats with spontaneous hypertension. In accordance, moxonidine is characterized by a low affinity for alpha-adrenoceptors and exhibits few side-effects. It is proposed that normalization of central sympathetic outflow represents a causal approach for improving crucial features of the metabolic syndrome.

Extended coverage for preventive services for the elderly: response and results in a demonstration population

OBJECTIVES

This study was undertaken to test the acceptability of preventive services under Medicare waivers to a community-dwelling population aged 65 and over and to examine the effect of such services on health.

METHODS

Medicare beneficiaries and designated primary care providers were sampled, and beneficiaries were screened and surveyed. A total of 4195 individuals were then randomized into intervention or control groups. Those in the intervention group were offered free preventive visits (under waivers) to their physicians. A follow-up survey of the entire group was administered after completion of the intervention.

RESULTS

Sixty-three percent of the intervention group made a preventive clinical visit, and about half of them a counseling visit. For men, being married and having a solo practitioner were positively associated with accepting the intervention services, while for women, having had a mammogram, having a confidant, having a high school education, and having a female practitioner were so associated. The intervention group showed a greater health benefit than did the control group and had a significantly lower death rate: 8.3% vs 11.1%.

CONCLUSIONS

Older individuals will respond to preventive programs, and such services will result in modest health gains.

Preventive services for the elderly: would coverage affect utilization and costs under Medicare?

OBJECTIVES

This study was undertaken to determine whether adding a benefit for preventive services to older Medicare beneficiaries would affect utilization and costs under Medicare.

METHODS

The demonstration used an experimental design, enrolling 4195 older, community-dwelling Medicare recipients. Medicare claims data for the 2 years in which the preventive visits occurred were compared for the intervention (n = 2105) and control (n = 2090) groups. Monthly allowable charges for Part A and Part B services and number of hospital discharges and ambulatory visits were compared.

RESULTS

There were no significant differences in the charges between the groups owing to the intervention, although total charges were somewhat lower for the intervention group even when the cost of the intervention was included. Charges for both groups rose significantly as would be expected for an aging population. A companion paper describes a modest health benefit.

CONCLUSIONS

There appears to be a modest health benefit with no negative cost impact. This finding gives an early quantitative basis for the discussion of whether to extend Medicare benefits to include a general preventive visit from a primary care clinician.

Practice guidelines and private insurers

Practice guidelines are an increasingly relevant feature of health insurance. One hundred and seventy-eight million people in the United States have some form of private health insurance coverage; coverage for 150 million of them is employment-related. Traditionally, this coverage was provided by employers purchasing a group contract under which an insurance carrier provided indemnity coverage for employees—that is, the insurance company paid all usual, customary, and reasonable charges incurred by an employee for medical care, subject in some cases to an annual deductible and to a percentage of covered expenses, co-paid by the employee, for each service. In recent years, however, employers in greater numbers have switched to so-called self-insurance plans in which employees’ health care claims are paid directly by the employer (although an insurance company or other third party may be retained to administer the claim payment process).

Prognosis-based futility guidelines: does anyone win? SUPPORT Investigators. Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatment

OBJECTIVE

Advocates for health care reform and others claim that significant savings could be achieved if "futile" care were eliminated. Our objective was to provide an initial estimate of the effects of a public policy that would preclude futile life-sustaining treatments, defined as those employed despite < or = 1% chance of surviving for 2 months.

DESIGN

Simulation using data from an observational cohort study.

SETTING

Five academic medical centers.

PATIENTS

Seriously ill hospitalized adults enrolled in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatment (SUPPORT).

METHODS

We examined the impact of prognosis-based futility guidelines on survival and hospital length of stay on a cohort of seriously ill adults. We calculated the number of days of hospitalization that would not be used if, on the third study day, life-sustaining treatment had been stopped or not initiated for subjects with estimated 2-month survival probability of < or = 1%.

RESULTS

Of the 4301 patients, 115 (2.7%) had an estimated chance of 2-month survival of < or = 1%. All but one of these 115 subjects died within 6 months. Almost 86% died within 5 days of prognosis. At the time of death, 92 subjects (80.0%) had had no attempt at resuscitation; 35 (30.4%) had had a life-sustaining mechanical ventilator withdrawn. A Do-Not-Resuscitate order was written either before (n = 61) or within 5 days (n = 18) of reaching this prognosis for 68.6% of the patients. These 115 subjects had total hospital charges of $8.8 million. By forgoing or withdrawing life-sustaining treatment in accord with a strict 1% futility guideline, 199 of 1,688 hospital days (10.8%) would be forgone, with estimated savings of $1.2 million in hospital charges. Nearly 75% of the savings in hospital days would have resulted from stopping treatment for 12 patients, six of whom were under 51 years old, and one of whom lived 10 months.

CONCLUSIONS

Patients at a high risk of dying can be identified prospectively. Implementation of a strict, prognosis-based futility guideline on the third day of a serious illness would result in modest savings.
