This dissertation examined the impact of Medicare Plan D on medication compliance in Medicare beneficiaries at University of Texas Health Center at Tyler, TX. Data were collected before and after the implementation of Plan D. The impacts of various types of benefits, such as private insurance, employer insurance and pharmacy assistance programs were evaluated in terms of impact on drug compliance. Medication compliance was found to increase in those respondents without Plan D. Plan D was found to be a predictor of those who spent less on basics in order to buy medications. Although compliance increased in general, these increases could not be attributed to the acquisition of a Plan D policy.
