Disenrollment from an acute/long-term managed care program (PACE).

BACKGROUND: The Program of All-Inclusive Care for the Elderly (PACE) is an acute/long-term managed care plan designed to care for the most frail and vulnerable Medicare beneficiaries. To our knowledge, this is a first study to examine patterns and predictors of disenrollment from PACE. OBJECTIVE: PACE, with its comprehensive delivery system, dual capitation, and a focus on the most vulnerable population, may be expected to achieve low rates of exit and little selective dissenrollment. This study examines whether these goals have been accomplished. RESEARCH DESIGN: The study includes 30 PACE programs and 14,657 individuals enrolled in them. Individual-level records, obtained from an administrative database, contain information on sociodemographics, caregiver support, health status and disability, medical history, service utilization, and disenrollment. Program-level variables also were included. Cox proportional hazard models, with time-varying and time-invariant covariates, were employed to predict time to disenrollment. RESULTS: Our findings show a low level of disenrollment. We find no increase in disenrollment risk by age, functional or cognitive impairment, Medicaid eligibility, or diagnoses. Certain characteristics (eg, nursing treatments) appear to reduce the disenrollment hazard, whereas others (eg, hospital admissions, private pay status) significantly increase it. The risk of disenrollment also increases with longer nursing home stays, until 80-90 days, whereupon it begins to decline. CONCLUSIONS: Both enrollee and program-level attributes predict program disenrollment. Programmatic and quality of care improvements may be needed to further minimize disenrollment, particularly in programs experiencing rates that are substantially greater than the average.

Improved asthma care after enrollment in the State Children's Health Insurance Program in New York.

BACKGROUND: Uninsured children with asthma are known to face barriers to asthma care, but little is known about the impact of health insurance on asthma care. OBJECTIVES: We sought to assess the impact of New York's State Children's Health Insurance Program (SCHIP) on health care for children with asthma. DESIGN: Parents of a stratified random sample of new enrollees in New York's SCHIP were interviewed by telephone shortly after enrollment (baseline, n = 2644 [74% of eligible children]) and 1 year later (follow-up, n = 2310 [87%]). Asthma was defined by parent report using questions based on National Heart, Lung, and Blood Institute criteria. A comparison group (n = 401) who enrolled in SCHIP 1 year later was interviewed as a test for secular trends. MAIN OUTCOME MEASURES: Access (having a usual source of care [USC], unmet health needs, problems receiving acute asthma care), asthma-related medical visits, quality (continuity of care at the USC, problems receiving chronic asthma care, use of antiinflammatory medications), and asthma outcomes (change in asthma care or severity) were the main outcome measures used. Bivariate and multivariate analyses compared measures at baseline (year before SCHIP) versus follow-up (year during SCHIP). RESULTS: Three-hundred eighty-three children (14%) had asthma at baseline, and 364 had asthma at follow-up (16%). No secular trends were detected between the baseline study group and the comparison group. After enrollment in SCHIP, improvements were noted in access: lacking a USC (decrease from 5% to 1%), unmet health needs (48% to 21%), and problems getting to the USC for asthma (13 to 4%). Children had fewer asthma-related attacks and medical visits after SCHIP (mean number of attacks: 9.5 to 3.8: mean number of asthma visits: 3.0 to 1.5; hospitalizations: 11% to 3%). Quality of asthma care improved for general measures (most/all visits to USC: 53% to 94%; mean rating of provider: 7.9 to 8.8 of 10) and asthma-specific measures (problems getting to the USC for asthma care when child was well: 13% to 1%). More than two thirds of the parents at follow-up reported that both quality of asthma care and asthma severity were "better or much better" than at baseline, generally because of insurance coverage or lower costs of medications and medical care. CONCLUSIONS: Enrollment in New York's SCHIP was associated with improvements in access to asthma care, quality of asthma care, and asthma-specific outcomes. These findings suggest that health insurance improves the health of children with asthma.

Nursing home spending patterns in the 1990s: the role of nursing home competition and excess demand.

OBJECTIVE: To examine nursing home expenditures on clinical, hotel, and administrative activities during the 1990s and to determine the association between nursing home competition and excess demand on expenditures. DATA SOURCES/STUDY SETTING: Secondary data sources for 1991, 1996, and 1999 for 500 free-standing nursing homes in New York State. STUDY DESIGN: A retrospective statistical analysis of nursing homes' expenditures. The dependent variables were clinical, hotel, and administrative costs in each year. Independent variables included outputs (inpatient and outpatient), wages, ownership, New York City location, and measures of competition and excess demand. DATA COLLECTION/EXTRACTION METHOD: Variables were constructed from annual financial reports submitted by the nursing homes, the Patient Review Instrument and Medicare enrollment data. PRINCIPAL FINDINGS: Clinical and administrative costs have increased over the decade, while hotel expenditures have declined. Increased competition was associated with higher clinical and administrative costs while excess demand was associated with lower clinical and hotel expenditures. CONCLUSIONS: Nursing home expenditures are sensitive to competition and excess demand conditions. Policies that influence competition in nursing home markets are therefore likely to have an impact on expenditures as well.

Variations in risk-adjusted outcomes in a managed acute/long-term care program for frail elderly individuals.

OBJECTIVE: To develop and investigate the properties of three performance measures based on risk-adjusted health outcomes for a frail, elderly, community-dwelling population enrolled in a managed, acute, and long-term care program. DESIGN: Retrospective analyses of an administrative dataset containing individual level records with information about socioeconomics, health, functional and cognitive status, diagnoses, and treatments. We estimated risk-adjustment models predicting mortality, decline in functional status, and decline in self-assessed health. Each model includes individual risk factors and indicator variables for the program site in which the individual enrolled. Sites were ranked based on their performance in each risk-adjusted outcome, and the properties of these performance measures were investigated. SETTING: Twenty-eight sites of the Program of All-Inclusive Care for the Elderly (PACE) that provide primary, acute, and long-term care services under capitated Medicare and Medicaid payment to a nursing home certifiable, and functionally and cognitively frail community-dwelling elderly population. STUDY PARTICIPANTS: Three thousand one hundred and thirty-eight individuals who were newly enrolled between 1 January 1998 and 31 December 1999. The average age of these enrollees was 78 years, 27% were male, 50% were diagnosed with dementia, and they had approximately 4 Activities of Daily Living limitations and 7.4 Instrumental Activities of Daily Living limitations. MAIN OUTCOME MEASURES: Risk-adjustment models, performance ranking for each site, and correlations between performance rankings. RESULTS: We present risk-adjustment models for mortality, change in functional status, and self-assessed health status. We found substantial variation across sites in performance, but no correlation between performance with respect to different outcomes. CONCLUSIONS: The variations in outcomes suggest that sites can improve their performance by learning from the practices of those with the best outcomes. Further research is required to identify processes of care that lead to best outcomes.

Social support and risk-adjusted mortality in a frail older population.

OBJECTIVE: The objective of this study was to test the hypothesis that social support is an important predictor of mortality in a frail older population receiving formal long-term care services. RESEARCH DESIGN AND METHODS: The analysis is based on 3138 individuals enrolled in 28 Programs of All-Inclusive Care for the Elderly (PACE). Information about the enrollees is obtained from dataPACE. Semiparametric Cox proportional hazards models are estimated to assess the importance of individual risk factors, program effect, and social support. RESULTS: The introduction of the social support variables into the mortality model containing the sociodemographic, health needs, and the PACE-site indicator variables results in a significant improvement of the overall model fit. Several social support variables are statistically significant predictors of mortality. Controlling for all participant and caregiver characteristics, participants whose caregiver is a spouse have a significantly lower risk of mortality (hazard ratio = 0.63) compared with those whose caregiver is not a spouse. Furthermore, caregivers' assistance with meals confers a significantly lower risk of morality (hazard ratio = 0.66) compared with no assistance with meals. CONCLUSIONS: This study shows that certain aspects of informal caregiving are important factors enhancing survival in a population of frail, nursing home-certifiable individuals enrolled in a health program that already provides extensive services, including personal care, chores, and meals. Further research to better differentiate between the affective versus the instrumental dimensions of social support is needed to guide programs on how to balance the use of resources to provide both the necessary formal services and the support for the informal caregivers.

Health care services utilization at the end of life in a managed care program integrating acute and long-term care.

BACKGROUND: The period preceding death is often characterized by increased utilization of medical resources. There is an ongoing debate on the reasons for and the appropriateness of increased utilization at the end of life. OBJECTIVES: To study end-of-life practices in the PACE program and to assess the contribution of individual characteristics versus program site to the variation in use of services. RESEARCH DESIGN: Retrospective analyses of utilization and health status data for the last 3 years before death. Multivariate regression techniques were used to estimate models predicting utilization of services and the percent of variation explained by individual characteristics and program sites in relation to time from death. SUBJECTS: The study comprised 2160 persons enrolled in 10 PACE sites who died before 2000. MEASURES: Monthly utilization by service type (eg, hospital, nursing home, primary care physicians), socioeconomic, and health status data. RESULTS: Utilization of health services increases as early as 7 months before death, with the largest increase in the last month. The increase is dominated by hospital use. During the last month before death variation across program sites explains twice as much of the variation in service utilization as does variation in individual characteristics. CONCLUSIONS: The variation in end-of-life practices across PACE program sites, which are not attributed to differences in individual characteristics, raises two important questions: what are the causes for these variations; and are these variations desirable? Further research is required to answer both questions.
