Stakeholder perspectives on facilitators and barriers to implementing a zero-dollar copay program for chronic...

Type 2 diabetes mellitus (T2D) remains a pressing public health concern. Despite advancements in antidiabetic medications, suboptimal medication adherence persists among many individuals with T2D, often due to the high cost of medications. To combat this issue, Blue Cross and Blue Shield of Louisiana (Blue Cross) introduced the $0 Drug Copay (ZDC) program, providing $0 copays for select drugs. This study sought to explore barriers and facilitators to the successful implementation of Blue Cross's ZDC program (updated version).

Focus group discussions and interviews were conducted with health plan leadership, health coaches and providers who participate in the health plan organization's healthcare quality improvement program. Focus group discussions and semi-structured interviews were conducted between October 2022 and July 2023. Discussion guides were developed collaboratively and tailored to each participant group. Interviews were recorded, transcribed and analysed using NVivo^® qualitative analysis software. A descriptive, qualitative analysis was conducted, resulting in the identification of seven codes and subsequent candidate themes.

In total, 15 participants were interviewed: 6 were Blue Cross administrators, 5 were health coaches and 4 were Quality Blue providers. Overall, participants had positive feedback on the ZDC program and perceived that it has significant benefits for patients and the health system but could be improved, and four themes related to implementation barriers and facilitators, effectiveness and potential areas of improvement were identified: (1) the ZDC program reduces friction for patients, prescribers and the health system; (2) the program is aligned with the values of health systems, insurers and providers, facilitating implementation success; (3) expanding coverage (drug classes and conditions) and education (for providers and patients) could maximize program benefits; and (4) coronavirus disease 2019 (COVID-19) did not negatively impact program administration because the $0 copay was programmed at the benefit level.

The ZDC program aligns goals and can benefit patients, providers and patients. The program can have the largest potential if it is expanded to include new medications and new conditions, and if there is more education for patients and providers. Regardless of challenges, reduced-copay programs have the potential to improve medication adherence, improve HbA1C control and improve overall health outcomes.
