Factors associated with medication adherence in frail urban older adults: a descriptive and explanatory study
Document
Description
The treatment of individuals with multiple chronic conditions represents the single largest driver of Medicare costs. The use of prescription drugs is a major component in the treatment/management of chronic disease in the United States. Medication nonadherence, however, is a common problem among older adults and leads to significant morbidity and mortality. Whereas, the problem of medication nonadherence has been a primary focus of research for the last thirty years, much is still unknown about which older adults are most at risk for medication nonadherence, as well as what are effective theory-based interventions to improve a person's medication self-management.
The purpose of this descriptive explanatory study was to better understand the self-management behavior, medication adherence, in a sample of frail urban older adults. The study used a combination of quantitative and qualitative methods to analyze data from a larger twelve-month study of a nurse care coordination intervention. Ryan and Sawin's (2009) Individual and Family Self-Management Theory served as the study's conceptual framework for identifying the context and processes involved in the older adults' medication self-management. Quantitative results found several individual- as well as family-level predictors for medication nonadherence. Qualitative analyses identified three overarching themes to describe the participants' struggles along the multistep process of medication adherence. Additionally, a cultural domain described the need for more information from participants to understand their nonadherence. Integration of the results further increased our understanding of medication-self management in these frail older adults, and offers direction for clinical practice and future research.
