Influence of age, sex, and race on prescription drug use among Georgia Medicaid recipients.

Interactions among patients' age, sex, and race that influence prescription drug use in a state Medicaid population are described. A database containing information about all 574,762 Medicaid prescriptions dispensed in Georgia during December 1985 was sorted and summarized so that each record represented one Medicaid recipient. The following data were included for each recipient: the total number of Medicaid prescriptions received by that patient during that month, the total payments made by the state for those prescriptions, and the patient's age, sex, and race.
