Hospital utilization and expenditures in a Medicaid population.
Determinants of hospital utilization and expenditures are analyzed for Medicaid enrollees in the State Medicaid household sample portion of the National Medical Care Utilization and Expenditure Survey who were continuously enrolled throughout 1980. Health status measures were the best predictors of both the probability of hospitalization and total hospitalizations. Children covered by Aid to Families with Dependent Children were the Medicaid enrollees least likely to be hospitalized. Number of hospital days, surgery, and California residence directly increased hospital expenditures. Conditions responsible for hospitalization increased hospital expenditures indirectly by increasing the number of hospital days and the probability of surgery.
