Objective: This article evaluates a demonstration program that extended coverage for disease prevention/health promotion services to Medicare beneficiaries., Study Setting/data Sources: Community-dwelling Medicare beneficiaries who lived in five rural counties in northwest Pennsylvania were recruited between May and December 1989. The demonstration lasted 18 months and beneficiaries were followed for an additional 18 months. Data for the evaluation came from an initial health risk assessment, Medicare administrative records, follow-up surveys, and redeemed vouchers for the waivered services. The waivered services included health screenings, influenza immunization, nutritional counseling, smoking and alcohol cessation, and depression/dementia evaluations., Study Design: Medicare beneficiaries were randomized to one of two experimental groups and a control group. One experimental group received the newly waived services from hospitals that received a capitated fee; the other received services from providers who were paid fee-for-service. Eligibility for most waivered services was based on risk. Chi-square tests of association were used to determine if use of health promotion services and use of medical care services varied across groups. Logistic regressions were used to assess the factors associated with participation. Product-limit survival analysis was used to assess whether mortality rates varied across groups., Principal Findings: Participation rates in the new programs varied by program and by experimental group, and ranged from 16.8 percent for smoking cessation programs to 58 percent for influenza immunization. The demonstration led to an increase in influenza immunization rates relative to the control group. There were no differences in the use of medical care services or health outcomes between the experimental and control groups., Conclusions: Older rural Americans will modestly increase their use of disease prevention/ health promotion services if they are covered by Medicare. Use will be higher among those with more education. Further research is needed to assess long-term benefits of such programs.

The Health Care Financing Administration (HCFA) funded a series of demonstration programs to learn about the implications of extending coverage for disease prevention/health promotion services to Medicare beneficiaries. This article examines the use of such services by a rural population under this demonstration program. Individuals enrolled in the demonstration were eligible for specific risk reduction interventions. They were enrolled in one of two groups: (1) a hospital-based group in which hospitals were paid a capitated fee for providing all services and (2) a physician-based group in which physicians were paid fee-for-service for providing each service. Chi-square tests of association as well as logistic regression models were used to assess whether eligibility for services, and use of services by those eligible, varied by group and by sociodemographic characteristics. Forty-one percent were eligible for a nutrition program, 11% for smoking cessation, 2% for alcohol counseling, and 7% for dementia/depression evaluations. Participation in the programs varied across the programs and within programs by gender, education, and group assignment. Older rural Americans will use some disease prevention/health promotion services if they are covered by Medicare. Use will be higher among those with more education. Rural beneficiaries are more likely to use preventive services if encouraged to do so by their doctors rather than by hospital-based programs.

Some epidemiologic studies have compared the characteristics of individuals who participate, refuse, and are unreachable in population studies, but results have been inconsistent. The Rural Health Promotion Project attempted to recruit all Medicare Part B noninstitutionalized individuals age 65-79 years in a rural community for a trial of preventive health services. Of 962 potential subjects, 360 (37.4%) participated, 253 (26.3%) refused, 176 (18.3%) were ineligible, and 152 (15.8%) were never reached by phone or mail. Approximately 3 years later, we reinterviewed the participants, refusals, and as many of the unreachables as possible. The 3-year mortality was similar for both refusals and participants (approximately 9%) but was much higher for ineligibles (29.0%) and unreachables (23.7%). Participants were more likely to have disease history, to have behavioral risk factors for disease, and to use health screening services. Refusals were the healthiest and possibly chose not to participate because they did not have risk factors targeted by the program. The unreachables had the highest prevalence of disability and health care inpatient reimbursement and may have been ineligible for the demonstration had they volunteered. We conclude that failure to reach potential participants for health promotion services may be a warning of "high risk."

Background: Although interest in health promotion for the elderly is increasing, the issues of recruitment into such programs and self-selection have not been well explored. While clinical studies require high participation levels and expensive recruitment, community efforts are satisfied with recruiting small numbers of volunteers from poorly defined populations. These small samples may not be representative of the populations at risk., Methods: As part of the Rural Health Promotion Project, a Medicare demonstration, community-based recruitment methods were evaluated and participant characteristics were compared. A total of 3,884 individuals ages 65-79 were recruited in northwestern Pennsylvania, using four sequential recruitment strategies, varying in aggressiveness. The methods were: (A) mail only, (B) mail with phone recruitment follow-up, (C) mail with phone recruitment and scheduling, and (D) mail with aggressive phone recruitment and scheduling., Results: Recruitment yields were Method A, 13.5%; B, 21.1%; and C, 31.6%. The most aggressive Method (D) yielded 37.0% participation. More aggressive methods (C and D) recruited more educated individuals. No other demographic or health status differences were noted., Conclusion: These data show that large numbers of the elderly can be recruited into a health promotion program using aggressive methods and professional interviewers.
