A Descriptive Study of HIV Patients Highly Adherent to Antiretroviral

HIV medication adherence is a topic of major public health concern in the United States. Adherent patients may be less likely to experience treatment failure, AIDS presentations and extreme medical costs. We evaluate a cohort of highly adherent Medicare beneficiaries to establish if the out of pocket costs of HIV medications are an inherent barrier to adherence. We analyzed a 100% sample of Medicare Part-D prescription medications. The drug and out ofpocket costs for HIV and non-HIV medications of highly adherent cohort were extracted and analyzed. The average gross drug cost per beneficiary was $34,029for HIV medications and $11,439for non-HIV medications. Average out of pocket costs per beneficiary was $454for HIV medications and $129 for non-HIV medications. Out of pocket costs do not reasonably appear to be a barrier to adherence for Part-D beneficiaries.
