The effects of capitation on health and functional status of the Medicaid elderly. A randomized trial.

PURPOSE: To determine the effect on health and functional status outcomes of enrollment of noninstitutionalized elderly Medicaid recipients in prepaid plans compared with traditional fee-for-service Medicaid. DESIGN: A randomized controlled trial. Beneficiaries were randomly assigned to prepaid care in one of seven capitated health plans compared with fee-for-service care. Only the Medicaid portion of their care was capitated. Patients were followed for 1 year. SETTING: The Medicaid Demonstration Project in Hennepin County, Minnesota, which includes Minneapolis. PATIENTS: 800 Medicaid beneficiaries who were 65 years or older at the beginning of the evaluation. Beneficiaries were interviewed at baseline (time 1) and 1 year later (time 2). Ninety-six percent of beneficiaries were available for follow-up interviews at time 2. MAIN OUTCOME MEASURES: General health status, physical functioning, mental health status, activities of daily living, instrumental activities of daily living, corrected visual acuity, and blood pressure and glycosylated hemoglobin measurements for hypertensive and diabetic persons, respectively. RESULTS: There were no differences between prepaid and fee-for-service groups in the number of deaths (20 compared with 24, P > 0.2), the proportion in fair or poor health (56.5% compared with 59.7%, P > 0.2), physical functioning, activities of daily living, visual acuity, or blood pressure or diabetic control. Patients in the prepaid group reported a trend toward better general health rating scores (10.2 compared with 9.8, P = 0.06) and well-being scores (10.0 compared with 9.7, P = 0.07) than patients in the fee-for-service group. The difference in the likelihood of a patient in the prepaid group having a physician visit relative to the fee-for-service group was -16.5% (adjusted odds ratio, 0.46; 95% CI, 0.29 to 0.74) and for an inpatient visit was -11.2% (adjusted odds ratio, 0.55; CI, 0.32 to 0.94). CONCLUSIONS: There was no evidence of harmful effects of enrolling elderly Medicaid patients in prepaid plans, at least in the short run. Whether these findings also apply to settings in which health maintenance organizations are formed exclusively for Medicaid patients should be studied further.

Health plan choice in the Twin Cities Medicare market.

This paper examines the relationship between characteristics of Medicare beneficiaries and their choice of health plan in the Twin Cities during 1988. This analysis provides the first comparison of beneficiaries in the basic fee-for-service (FFS) Medicare sector (without a supplementary policy) to beneficiaries in the FFS sector with a supplementary policy, enrollees in independent practice associations (IPAs), and network health maintenance organizations (HMOs). The site and time period are important because there were five large, mature HMOs with TEFRA-risk contracts operating at that time, enrolling 50% of Medicare beneficiaries in the market area. We find that the oldest, poorest and, to a lesser extent, the sickest Medicare beneficiaries were most likely to have basic FFS Medicare coverage without supplementary insurance. The youngest enrollees are found in network HMOs. The availability of group coverage and premium subsidies are positively associated with choice of FFS with a supplementary policy. Government policy concerning Medicare HMO premiums appears to contribute to the poorest beneficiaries facing the highest out-of-pocket costs.

The use of new technologies by rural family physicians.

BACKGROUND: Although office procedures that involve special training and office equipment are often performed by a specialist in an urban setting, they are increasingly being performed by family physicians in rural settings. This study documents the prevalence of four such procedures in rural family practice: flexible sigmoidoscopy, cardiac stress testing, colposcopy, and nasopharyngoscopy. Individual and community characteristics of physicians who perform each of the procedures are compared with those of physicians who do not. METHODS: Data were collected on office technology and the characteristics of physicians, their practices, and their communities through telephone interviews with 403 randomly selected, rural family physicians and general practitioners in eight states. Descriptive and univariate analyses were used. RESULTS: Flexible fiberoptic sigmoidoscopy was performed by 57% of the physicians in our sample. The presence of another physician in the group or in the community who performed this procedure increased the probability of a rural physician performing it. Being male, recent licensure, board certification, and patient volume were also positively associated with the performance of this procedure. CONCLUSIONS: This study found evidence of a collegial effect among rural physicians and of a significant number of rural physicians seeking postresidency training in new procedures.

Health care reform and rural health networks.

Health care reform is likely to raise unique issues for rural communities and providers. This paper identifies and discusses several of these issues, with a particular focus on the potential relationship between health care reform and rural health networks. Topics addressed include the likely impact of health reform on the organization and development of rural health networks, the reimbursement of rural providers, rural medical practice, and state roles in the organization, delivery, and oversight of rural health care.

Access and use of health services by chronically mentally ill Medicaid beneficiaries.

This article has two objectives: to quantify the access and utilization of services received by chronically mentally ill Medicaid recipients, and to compare service utilization and access under prepayment and fee-for-service (FFS) payment. The study setting is Hennepin County (Minneapolis), Minnesota, where 35 percent of Medicaid recipients were randomly assigned to receive services from prepaid plans. An algorithm was developed to identify recipients with chronic mental illness, resulting in 739 study participants, split approximately evenly between prepayment and FFS Medicaid. Data were collected through in-person surveys at baseline, and after 1 year. We found slight improvements in the majority of access measures studied and no significant decreases in the use of inpatient or outpatient services for enrollees in prepaid health plans. The results support efforts to expand the use of prepaid health plans to meet the needs of non-institutionalized chronically mentally ill Medicaid beneficiaries.

A clinically based service limitation option for alternative model rural hospitals.

Alternative model rural hospitals are designed to address problems faced by small, isolated rural hospitals. Typically, hospital regulations are reduced in exchange for a limit on the services that alternative models may offer. The most common service limitation is a limit on length of stay (LOS), a method with little empirical or conceptual support. The purpose of this article is to present a clinically based service limitation for alternative model rural hospitals, such as the rural primary care hospital. The proposal is based on an analysis of Medicare discharges from rural hospitals most likely to convert and the judgments of a technical advisory panel of rural clinicians.

Accuracy of diagnoses of schizophrenia in Medicaid claims.

Medical insurance claims are increasingly important as a source of data in monitoring health care utilization and patient outcomes and in identifying patient cohorts for research. In a study that attempted to verify that those with Medicaid claims for treatment of schizophrenia did indeed have the disorder, two psychiatrists evaluated clinical information obtained from primary mental health care providers in relation to DSM-III-R criteria. The psychiatrists classified 86.8 percent of 319 patients with claims for treatment of schizophrenia and 27.5 percent of 156 patients with claims for treatment of other psychiatric diagnoses as definitely or probably having schizophrenia. The authors conclude that most diagnoses of schizophrenia listed on Medicaid claims are accurate, but that a substantial number of individuals with schizophrenia may not be identified by claims data.

The structure and characteristics of rural hospital consortia.

Rural hospital consortia are relatively new organizations that have been developed to help improve the viability of participating hospitals. This paper describes the characteristics of rural hospital consortia in the United States and develops and tests a measurement model of their underlying structure. The measurement model, which characterized consortia structure in terms of degree of member commitment, degree of complexity, scale of operations, and degree of formalization, provided a good fit to the sample data. Most consortia appear to have followed a relatively conservative course that involved the development of programs that had limited sensitivity and financial risk for individual hospitals. This suggests that rural hospital consortia may not become a model for major structural change in the rural health care system. Future research should examine the evolution of rural hospital consortia from an organizational life cycle perspective.

Mainstreaming the mentally ill in HMOs.

Administratively complex and politically sensitive issues can arise when mentally ill persons who are public program beneficiaries are enrolled in existing HMOs. The experiences of a demonstration program undertaken in Minnesota illustrate these issues.

Strategies for promoting a viable rural health care system.

Strategies for promoting a viable rural health care system in the context of the rapidly changing rural health care environment are presented. Also included is a series of guiding principles that support rural health care. They focus on the need for cooperation rather than competition among rural communities and health providers; the need for leadership and empowerment in rural communities; the dependence of rural health on generalists; the need to transform the reimbursement system to reward rural health services; the importance of quality of care for rural providers; the challenge of providing health and social services to the aged; and the instability caused by uncertain government attention to rural concerns. Examples of current activities that exemplify the effective use of these principles with respect to rural hospitals are discussed. These include the proposed demonstration of a new health care institution called the Medical Assistance Facility, the development of rural hospital consortia, the establishment of a rural health care transition grants program, and the activities of the New York State Legislative Commission on Rural Resources.

Health insurance and welfare reentry.

This study presents a theoretical model of welfare reentry that examines the importance of private health insurance in determining whether working recipients terminated from Aid to Families with Dependent Children (AFDC) as a result of the Omnibus Budget Reconciliation Act returned to welfare over a two-year period. Our empirical results suggest that the lack of private health insurance is a statistically significant and quantitatively important determinant of welfare reentry. Since the vast majority of the terminated families remained off welfare, however, these results suggest the difficulty of meeting the health needs of the employed uninsured.

Allocative efficiency of case managers for the elderly.

This study presents an analysis of the allocative efficiency of case managers for the community-based elderly in an environment in which case management and a range of home and community-based services were available and directly linked to a mandatory preadmission screening program for nursing home applicants. We collected data for a one-year follow-up period on client placement, health and functional status, informal support, and use of health and social services for clients in two urban and two rural counties that participated in the Minnesota Pre-Admission Screening/Alternative Care Grants Program (PAS/ACG). We found that among those receiving ACG-supported services, the relationship between variation in the level of support for home and community-based services and the length of time elderly clients remained in the community suggested that case managers were allocating home and community-based services in a reasonably efficient manner. This finding offers support for using case managers to target services to the elderly.

Substitution of formal and informal care for the community-based elderly.

The Minnesota Pre-Admission Screening/Alternative Care Grants Program screens those at risk of nursing home placement and funds services that will allow the elderly to be cared for at home. Information was collected for a 1-year period on client placement, health and functional status, informal support, use of health and formal services, and care-giver characteristics for 214 clients screened during the last quarter of 1984. A two-equation model was hypothesized to examine the formal service decisions of case managers and the amount of informal care provided for elderly clients at risk of institutionalization. A system of two simultaneous equations was estimated using a two-stage least-squares approach. The findings suggest that case managers allocate formal services based primarily on client need. The amount of informal care provided to clients did not affect significantly the decisions of case managers and is not determined significantly by the amount of formal services received by the elderly in the community. The lack of substitution between formal services and informal care reinforces the findings of previous research.

Health care and insurance loss of working AFDC recipients.

The federal Omnibus Budget Reconciliation Act of 1981 (OBRA) produced substantial changes in the Aid to Families With Dependent Children (AFDC) program. The main effect of the changes has been the denial of assistance and hence Medicaid coverage to many AFDC recipients with jobs. Our analysis of the health care and insurance loss of working AFDC recipients in Hennepin County, Minnesota, found that the vast majority (87%) of families that were terminated from AFDC due to OBRA were able to remain off welfare and the majority (70% adults, 60% children) had private health insurance coverage 2 years later. These results highlight the dilemma facing state policymakers who want to develop successful programs to meet the health needs of the working poor, yet at the same time must cope with tight, short-term fiscal constraints.

A prognosis for the rural hospital. Part I: What is the role of the rural hospital?

The rural hospital is a vital component of the rural health care delivery system and an important institution in rural communities. In recent years, considerable concern has been expressed over the future of these institutions, many of which have experienced serious difficulties in maintaining financial viability. The problems facing many rural hospitals today result from a number of interrelated factors, both internal and external, that determine the environment within which the rural hospital operates and affect its performance. This is the first of a two-part series that: provides an objective review and critical analysis of what is known and what is not known from the existing body of research on the performance of rural hospitals; identifies and examines the influence of the major external factors which affect viability; and outlines potential options and strategies for strengthening the viability of these institutions. Part I addresses the issues of scope of services and quality of care in rural hospitals.

A prognosis for the rural hospital: Part II: Are rural hospitals economically viable?

This is the second of a two part series that summarizes what is known about the operation and performance of the rural hospital and discusses potential options and strategies for strengthening the viability of these institutions. In Part II, we focus on the economic viability of the rural hospital and examine external factors that influence the environment within which the rural hospital operates. We conclude that the future will remain precarious for rural hospitals and that they can hope to improve their economic viability only if they are able to determine where they fit as part of the large health care system.
