OBJECTIVE In 1990, the state of Florida implemented an acquired immunodeficiency syndrome (AIDS)-specific Medicaid waiver program to provide home and community-based services to AIDS patients as an alternative to institutional care. The program is available to Medicaid beneficiaries with AIDS who are at risk of institutionalization. This study examines whether the waiver option was effective in reducing Medicaid expenditures per beneficiary during its first 2 years of operation. METHODS The authors used Medicaid claims data and county information on the availability of health services to model the selection of the waiver option by AIDS patients and then to estimate the effect of the waiver on expenditures controlling for nonrandom program selection. RESULTS The results indicate that the selection model is highly significant, but that the influence of nonrandom selection on the estimation of the program effects is negligible. More importantly, the regression results indicate that persons with AIDS who use waiver services incur monthly Medicaid expenditures that are on average 22% to 27% lower than otherwise similar nonparticipants. CONCLUSIONS These results, based on the first 2 years that Project AIDS Care was operational, suggest that home and community-based care for AIDS patients results in lower expenditures per beneficiary.

D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
