Distance to pharmacy and risk of medication primary nonadherence.

Primary nonadherence, a form of prescription nonadherence, is defined as failure to fill and pick up a prescription medication. Little is known about the relationship between distance to pharmacy and primary nonadherence in dermatology. In this study, we investigated the association between primary nonadherence and distance between a patient's home and pharmacy. We focused on a low-income patient population within the dermatology clinic of a large, urban county hospital system in which patients were enrolled in a pharmacy benefit within a closed-system. Among 678 patients who were prescribed a total of 1156 prescription medications for dermatologic conditions, 11.7% did not pick up any of their prescriptions. After adjusting for patient demographics of race/ethnicity, sex, age, language, and relationship status, there was no association between primary nonadherence and distance traveled between a patient's home and pharmacy. Results of this study are consistent with other studies in non-dermatologic patients and suggtableest that distance from a pharmacy may not be strongly associated with primary nonadherence for dermatologic medications.
