Homing in on the homeless: assessing the physical health of homeless adults in Los Angeles County using an original method to obtain physical examination data in a survey.

OBJECTIVE: Public policy that decreases the finding for social services may combine with the ascendancy of corporate managed care to increase the health care deficit. Assessing the health impact of these policy changes on various populations is a fundamental challenge for health services research. Disadvantaged populations, such as the homeless, are likely to be affected disproportionately. Research quality data on the physical health of such populations are difficult and expensive to obtain. In particular, physical examination data have not been available and self-reports are insufficient. Our objective: to develop and utilize a structured physical exam system enabling lay survey researchers to report reliably physical findings related to six tracer conditions in a disadvantaged population. STUDY SETTING: A field survey of homeless adults in Los Angeles County, California. Respondents were 363 homeless adults representing a subsample of a probability sample of the county's homeless adult population. STUDY DESIGN: We integrated existing measures with expert clinical opinion and original means of data collection into a structured physical exam enabling lay interviewers to identify the prevalence of vision problems, significant skin disorders, peripheral vascular disease of the lower extremities, selected podiatric disorders, hypertension, and tuberculosis in a sample of homeless adults. PRINCIPAL MEASURES: We describe lay interviewer performance in terms of mastery of the necessary material based on written and practical exams and in terms of the number of respondents successfully followed. We base our description of the instrument on the time necessary to complete it, and on the proportion of each component successfully completed during the field survey, as well as on interrater reliability. We report the prevalence of the various clinical conditions according to self-report and according to the structured limited physical exam, as well as the marginal proportion of respondents who were identified by the physical exam and not by self-report. PRINCIPAL FINDINGS: Interviewers performed the exam successfully under field conditions. Respondent acceptance of the instrument was high. Interrater agreement was 100 percent regarding the need for referral on the basis of blood pressure and vision. Kappa statistics for skin, foot, and edema findings were .67,.71, and .81, respectively. Adjusted for sampling weights, 60 percent of this population required referral for at least one of the specified conditions. For those portions of the survey for which both self-report and physical exam data were available, lay interviewers made significant percentages of referrals on the basis of physical findings alone. CONCLUSIONS: High blood pressure, poor vision, peripheral vascular diseases of the feet and legs, and significant skin conditions are prevalent among the homeless in Los Angeles County. Without physical exam data, estimates of the prevalence of these conditions will be incorrect. Researchers can use laypersons to collect reliable and valid physical exam data on disadvantaged populations. This represents a new tool for assessing and monitoring the health of these populations.

A critique of an evaluation of the impact of hospital bed closures in Winnipeg, Canada: lessons to be learned from evaluation research methods.

In the last few years, the continuing increases in health care expenditures have led to a call for greater accountability in health care and have spurred evaluative research into the area of health care policy. Yet the challenge has been to develop health care policy evaluations that maximize the rigor of the evaluation process within the constraints and limitations of evaluation milieus. This paper describes the principles of evaluation research and, using the example of a study evaluating the impact of hospital bed closures on community health status in Winnipeg, Canada, demonstrates the epistemological, methodological and interpretive problems that can occur when these principles are not followed. The conclusions are that studies which fail to outline the causal links between policy actions and outcomes, and use designs and methods which threaten internal and external validity, are limited in their abilities to elucidate the impact of health care policy changes.

Where do elderly veterans obtain care for acute myocardial infarction: Department of Veterans Affairs or Medicare?

OBJECTIVE: To examine Department of Veterans Affairs (VA) and Medicare hospitalizations for elderly veterans with acute myocardial infarction (AMI), their use of cardiac procedures in both systems, and patient mortality. DATA SOURCES: Merging of inpatient discharge abstracts obtained from VA Patient Treatment Files (PTF) and Medicare MedPAR Part A files. STUDY DESIGN: A retrospective cohort study of male veterans 65 years or older who were prior users of the VA medical system (veteran-users) and who were initially admitted to a VA or Medicare hospital with a primary diagnosis of AMI at some time from January 1, 1988 through December 31, 1990 (N = 25,312). We examined the use of cardiac catheterization, coronary bypass surgery, and percutaneous transluminal coronary angioplasty in the 90 days after initial admission for AMI in both VA and Medicare systems, and survival at 30 days, 90 days, and one year. Other key measures included patient age, race, marital status, comorbidities, cardiac complications, prior utilization, and the availability of cardiac technology at the admitting hospital. PRINCIPAL FINDINGS: More than half of veteran-users (54 percent) were initially hospitalized in a Medicare hospital when they suffered an AMI. These Medicare index patients were more likely to receive cardiac catheterization (OR 1.24, 95% C.I. 1.17-1.32), coronary bypass surgery (OR 2.01, 95% C.I. 1.83-2.20), and percutaneous transluminal coronary angioplasty (OR 2.56, 95% C.I. 2.30-2.85) than VA index patients. Small proportions of patients crossed over between systems of care for catheterization procedures (VA to Medicare = 3.3%, and Medicare to VA = 5.1%). Many VA index patients crossed over to Medicare hospitals to obtain bypass surgery (27.6 percent) or coronary angioplasty (12.1 percent). Mortality was not significantly different between veteran-users who were initially admitted to VA versus Medicare hospitals. CONCLUSIONS: Dual-system utilization highlights the need to look at both systems of care when evaluating access, costs, and quality either in VA or in Medicare systems. Policy changes that affect access to and utilization of one system may lead to unpredictable results in the other.

Attitudes about AIDS education and condom availability among parents of high school students in New York City: a focus group approach.

This paper describes parents' views of the New York City Public High School's AIDS Education and Condom Availability Program. It presents findings from 12 focus groups with 81 parents of students at six representative high schools. Focus groups were conducted as part of an independent, comprehensive 3-year evaluation of the program, consisting of both qualitative and quantitative components. Participants were mostly supportive of the program, citing intense concern about AIDS among adolescents, fear that teenagers do not adequately perceive themselves as being vulnerable, and personal experiences with infected relatives and friends. Implications of these findings for program development are discussed and recommendations for social policy changes are presented.

Turning job finders into job keepers.

Most welfare-to-work programs designed to help single mothers leave welfare for employment focus on the challenge of finding a job. This article looks beyond the point of employment to consider the difficulty many former welfare recipients have keeping their jobs. The authors review evidence showing that many families cycle back and forth between welfare and work, losing jobs and returning to public assistance while they seek work again. Factors contributing to high rates of job loss include characteristics of the job and of the worker. Temporary jobs, frequent layoffs, low pay in relation to work expenses, lack of experience meeting employer expectations, and personal or family problems all lead to dismissals and resignations. Drawing from the experience of innovative programs, the authors recommend policy changes and program approaches that can help families overcome setbacks and stabilize their lives as they move from welfare into increasingly stable employment.

What should be the elements of any settlement with the tobacco industry?

Litigation and regulatory assaults on the tobacco companies may create a willingness among tobacco manufacturers to bargain resources and acceptance of public policy changes for limitations of liability, as has been seen by the recent settlement with the Liggett Group. Two elements absolutely critical to any plan are the elimination of tobacco advertising and promotion and the removal of addiction as a reason for tobacco use. Minimal components of any settlement should include: (a) acceptance by the tobacco manufacturers of the causal relationship between tobacco use and disease, and the addictive nature of nicotine; (b) a total ban on tobacco advertising and promotion; (c) FDA jurisdiction over tobacco products and their nicotine content, with the intent of removing nicotine as soon as acceptable nicotine substitution products are available; (d) reimbursement to the states for Medicaid and other state expenditures attributable to smoking, to the maximum extent feasible; (e) funding for local, state, and federal programmes and research in tobacco control; (f) acceptance of legislation and regulations protecting the right of non-smokers to breathe air free of tobacco smoke; (g) funding for a large, national, media-led, anti-tobacco campaign; and (h) cessation assistance for addicted smokers. If negotiations toward a settlement proceed, it is essential that the public health community participate in defining the elements of any agreement to ensure that whatever agreement develops is focused on reducing tobacco-related disease rather than continuing the profitability of American tobacco companies. That participation requires articulation of the core elements essential to an acceptable agreement. If resolution of the public health issues surrounding continued sale of tobacco products can be reached in the United States, it may provide a model for similar resolution in other countries.

Community prevention and alcohol retail access.

This paper describes the design, rationale and implementation of the Alcohol Access Component within the Community Trials Project of the Prevention Research Center. The Alcohol Access Component was to reduce the concentration or density of alcohol outlets in each experimental community by a combination of local zoning and land-use planning approaches which was an effect to occur over several years. During the time of this trial, local regulations of alcohol outlets and public sites for drinking were changed in all three experimental communities. The amount of such alcohol policy change exceeded the goals for this component.

Effect of Medicaid expansions on preterm birth.

OBJECTIVES: Inadequate prenatal care is thought to be a major modifiable risk factor for preterm birth, the leading cause of neonatal mortality. To improve high-risk women's financial access to prenatal care, the U.S. Medicaid program underwent major expansions during the 1980s. We evaluated these expansions over the nine-year period 1983 to 1991 in Tennessee to determine their effects on Medicaid enrollment, use of prenatal care, and preterm birth. METHODS: We used linked birth certificates, Medicaid data, and U.S. Census files to identify 610,056 singleton births to African-American or Caucasian women in Tennessee whose last menstrual period was between 1983 and 1991. These were classified by maternal characteristics to identify groups with the greatest postexpansion increases in Medicaid enrollment, which should have benefited most from the policy changes. Study outcomes were Medicaid enrollment by delivery, enrollment in the first trimester, inadequate prenatal care (modified Kessner index), and preterm (< 37 weeks) birth. We calculated the changes (delta expressed as births per 100) between 1983 and 1991 in percentages of births with each of these outcomes. RESULTS: The expansions led to pronounced increases in maternal Medicaid enrollment by delivery (21% of births in 1983 to 51% by 1991) and in the first trimester (from 10% to 37%). Married women with < 12 years of education, < 25 years of age, and < $12,500 mean neighborhood incomes (group 1) had the greatest increase, where enrollment and first-trimester enrollment increased from 24% to 86% and 7% to 68%, respectively. In group 1, the percentages of births with inadequate maternal use of prenatal care decreased substantially, from 12.8% in 1983 to 6.4% in 1991, a reduction of 6.4 births per 100 (95% confidence intervals [CI] = -7.6, -5.3). However, the preterm birth rate did not decrease (9.1% in 1983, 9.4% in 1991, change of 0.3[-0.7 to 1.2] births per 100). For other births, there were lesser increases in Medicaid enrollment, correspondingly lesser decreases in inadequate use of prenatal care, but no reductions in preterm birth rates. CONCLUSIONS: In Tennessee, the Medicaid expansions materially increased enrollment and use of prenatal care among high-risk women, but did not reduce the likelihood of preterm birth.

Health policy and the nursing profession: a deafening silence.

The Australian healthcare system, and those of many other Western countries are experiencing significant shifts in the development of health policy. Many of these shifts are directly related to economic factors that have contributed to the spiralling costs of health care. The trends in health policy appear to be embracing a 'market driven' approach to the distribution of resources and health services. Technology and medical developments have contributed to these current economic trends. Over the past 20 years nurses have been faced with significant shifts in the direction of health policy to the extent that many policies have significantly impacted upon their practice without their apparent contribution. Several theoretical positions exist about nurses' lack of policy participation. This paper examines some of the current health policy changes in Australia that are perceived to have had the greatest impact on the nursing practice, and identifies some of the barriers to the nursing profession's participation in the formulation of health policy.

Defining 'competency' in nursing (Part I): A policy review.

How the nursing profession in England defines the basic competency of the registered general nurse is crucial for the safety of the patient and the protection of the nurse. It is also essential for determining advanced practice, extended practice and specialist practice in nursing. An historical overview of documentation from the United Kingdom Central Council for Midwifery and Health Visiting, the English National Board for Nursing, Midwifery and Health Visiting and the Royal College of Nursing shows a profound change in educational policy during the 1980s regarding the interpretation of nursing competency. The effects of this policy change on the current methods developed to define, teach and test nursing competency are examined. Preliminary conclusions show shortcomings and uncertainty in the present preparation and evaluation of nursing competency.

Impact of banning alcohol on outpatient visits in Barrow, Alaska.

CONTEXT: Community availability of alcohol affects alcohol consumption patterns and alcohol-related health and social problems. In Barrow, Alaska, an isolated community at the northernmost reaches of the United States, during a 33-month period, possession and importation of alcohol were legal, completely banned, made legal again, and then banned again. OBJECTIVE: To determine the impact of these public policy changes on alcohol-related outpatient visits at the area hospital. DESIGN: Retrospective review of outpatient records; time-series analysis of alcohol-related visits with respect to community alcohol policy. MAIN OUTCOME MEASURES: Total monthly outpatient visits for alcohol-related problems. RESULTS: There was a substantial decrease in the number of alcohol-related outpatient visits when the ban on possession and importation was imposed compared with baseline. When the ban was lifted, outpatient visits increased; when the ban was reimposed, the number of outpatient visits again decreased. Interrupted time-series analyses confirm that the alcohol ban, its lifting, and its reimposition had a statistically significant and negative effect on the number of alcohol-related outpatient visits (P<.05). CONCLUSION: In a geographically isolated community, the prohibition of alcohol can be an effective public health intervention, reducing the health problems associated with alcohol use.

Restructuring federalism: the impact of Reagan policies on the family planning program.

Through fiscal cutbacks and structural changes, Reagan's federalism assaulted the ethos of public health. In assessing the effects of Reagan policies on a basic public health program, family planning services, we find a substantial decrease in spending for this program, a reduction in the numbers of patients served, and increased variation among the states in the provision of services to low-income women. These effects are comparable with findings from other studies on the impact of Reagan's federalism upon social programs and have manifold implications for public health.

Public policy and female sterilization in Costa Rica.

For 20 years, female sterilization has been increasing in popularity as a contraceptive method in Costa Rica. However, contraceptive sterilization has never been allowed explicitly under Costa Rican law. In 1976 the Costa Rican National Assembly instituted more stringent guidelines regarding medical sterilizations in order to eliminate contraceptive sterilizations, which had been occurring under relatively loose interpretations of national policy. Data from the 1976 National Fertility Survey and the 1981 Contraceptive Prevalence Survey indicate that the change in policy had only a short-term effect. Period sterilization rates fell substantially after 1976 but rebounded considerably by 1980, and the estimate of the proportion of married women who will ultimately be sterilized was approximately .5 for the periods both before and after 1976.

A comparison of the determinants of safe injecting and condom use among injecting drug users.

A sample of 582 injecting drug users were interviewed as part of an evaluation of an AIDS prevention programme for drug users. This paper examines the biographic and predispositional determinants of five HIV preventive behaviours--equipment sharing (not receiving and not giving) and and condom use (with regular partners, casual partners and sex clients). A two-stage sequential approach was adopted for a logistic regression analysis. Initially, to model each of the five preventive behaviours, biographical and drug use variables were entered. In a second set of models, behavioural predisposition factors were included. Age, drug use and prison experience correlate with variables in both models, although not consistently in the same direction. While a predisposition to reject sharing correlates with safer rejecting and condom use, the predisposition to safer sex only correlates with condom use. Needle exchange programmes that only target the individual would seem to be inadequate. To enhance targeted interventions changes in public and agency policy that create a social environment conductive to behaviour change are required.

Perinatal mortality in rural Tanzania.

Prolonged labour was the most frequent cause of perinatal death in a rural hospital in the south western highlands of Tanzania. After the introduction of an obstetric policy aiming to prevent prolonged labour by making use of the guidelines of the partogram, perinatal mortality was reduced from 71 to 39 per 1000 births. Baird's clinico-pathological classification is still considered a useful instrument for the discovery of avoidable factors in perinatal deaths. The concept of the partogram should be an integral part of the training of medical auxiliaries in the field of maternal and child health (MCH).

Fertility intentions and subsequent behavior: a longitudinal study in rural India.

This report compares fertility and family planning intentions of rural Indian women in 1975 with actual outcomes in 1987. Ninety-four of 103 respondents who had fewer children than they wanted in 1975 and had stated definite intentions with respect to future fertility and contraceptive use were reinterviewed in 1987. Overall, women had fewer children than desired and stopped childbearing when they reached or closely approximated their ideal number of sons. Since sons were clearly the determinant of "reproductive success," it is argued that only a significant change in the status of rural women can bring about widespread compliance with the official family planning program's two-child norm.
