Abstract:
his paper describes the common data source and methods used in this
study. Data come from the Community Tracking Study Household Survey, a nationally
representative survey of individuals conducted in 1996-1997. Focusing on the privately
insured, nonelderly population, the study examines the effect of health maintenance
organizations (HMOs) on access, service use, and consumer assessments, as well as how
these effects differ across population subgroups. Multivariate models control for
population characteristics and location differences between HMO and non-HMO enrollees.
Tests for endogeneity of plan type (selection bias) indicated that this did not pose a
threat to the analysis.
