Abstract:

PURPOSE: The goal of this study is to determine barriers and facilitators to the implementation of medication adherence interventions to support cancer patients taking novel, targeted oral anticancer agents (OAAs). METHODS: We conducted qualitative interviews using a semi-structured guide from the Consolidated Framework for Implementation Research (CFIR). We used purposive sampling to identify clinicians (physicians, pharmacists, nurse practitioners, nurses) and administrators (leadership from medicine, pharmacy, and nursing) who delivered care and/or oversee care delivery for patients with chronic leukemia prescribed an OAA. RESULTS: A total of 19 individuals participated in an interview (12 clinicians and 7 administrators), with 10 primarily employed by an academic cancer center; 5 employed by the community cancer center; and 4 employed by the integrated health-system specialty pharmacy. Barriers identified included low awareness of adherence interventions, difficulty in adherence measurement, complexity of designing and implementing a structured adherence intervention, and competing priorities. Facilitators identified included support of hospital administrators, value for pharmacists, and willingness to embrace change. Participants also made recommendations moving forward including standardizing workflow, designating champions, iterating implementation strategies, and improving communication between clinicians and with patients. CONCLUSION: Individual and system level factors were identified as determinants of implementation effectiveness of medication adherence interventions. A multidisciplinary advisory panel will be assembled to design comprehensive and actionable strategies to refine and implement a structured intervention to improve medication adherence in cancer patients.
