Descriptive study of homeless patients' perceptions that affect medication adherence

Results of a study to elucidate perceptions, attitudes, and beliefs about prescribed medications held by hospitalized patients who are homeless are reported.

A qualitative descriptive study involving semistructured interviews was conducted to gather information and characterize hospitalized homeless patients' views and attitudes regarding medication use, with a focus on medication nonadherence. Medication nonadherence has been shown to be a factor contributing to higher rates of emergency department visits, increased hospital lengths of stay, and increased healthcare costs in homeless populations. Interviews were conducted during patients' admissions to the internal medicine service of a tertiary care, inner-city hospital. Interviews were audio-recorded and transcribed. Data were analyzed using conventional qualitative content analysis to generate data-driven codes and themes.

Twelve interviews were conducted (median patient age, 48.5 years). Eight patients (66.7%) were living in a shelter, and 11 (91.7%) had a mental illness. Patients were prescribed a median of 4 medications at the time of hospital admission. Four themes were identified: (1) a new appreciation of medications was acquired during hospitalization, (2) medications were perceived as necessary for maintaining health, (3) there was an interest in receiving medication education, and (4) concerns were expressed regarding medication adverse effects.

In interviews conducted during hospital admission, homeless patients expressed positive perceptions about the necessity of their medications but also concerns about medication adverse effects. Interventions to improve adherence may be successful if directed toward addressing treatment-related concerns.
