The Pharmacist, Physician, and Patient Navigator-Collaborative Care Model (PPP-CCM) is a promising approach to delivering hepatitis C virus (HCV) care for people who inject drugs (PWID). The formative evaluation revealed that the model is feasible but faces challenges in delivering care efficiently. The role and characteristics of pharmacists, as well as financial barriers, are key factors to consider for the scalability and sustainability of PPP-CCM.
Background: Direct-acting antivirals (DAAs) offer an unprecedented opportunity to eliminate hepatitis C virus (HCV) infection, yet barriers among people who inject drugs (PWID) remain. Having pharmacists provide care through collaborative drug therapy agreements (CDTAs) offers a promising solution. We developed and piloted a Pharmacist, Physician, and Patient Navigator-Collaborative Care Model (PPP-CCM) which utilized pharmacists to directly deliver HCV care at community organizations serving PWID. We conducted formative evaluation of the PPP-CCM pilot to characterize implementation experiences. Methods: The PPP-CCM was implemented from November of 2020 through July of 2022. Formative evalua-tion team members observed implementation-related meetings and conducted multiple site visits, taking detailed fieldnotes. Fieldnotes were iteratively reviewed to identify barriers and facilitators to implementation and used to inform 7 key informant interviews conducted with programmatic staff at the end of the pilot. All data were analyzed using a Rapid Assessment Process (RAP) guided by the Consolidated Framework for Implementation Re-search (CFIR). The formative evaluation team shared results with program stakeholders (pharmacists, physicians, and other site staff) to verify and expand on learnings. Results: Evaluation of PPP-CCM revealed 5 themes, encompassing all CFIR domains: 1) PPP-CCM was feasible but challenging to deliver efficiently; 2) the pharmacist role and characteristics (e.g., being flexible, available, and patient-centered) were key to PPP-CCM successes; 3) the PPP-CCM team met challenges engaging patients over time, but some team-based strategies helped; 4) community site characteristics (e.g., existing trusting re-lationships with PWID and physical space that enabled program visibility) were important contributors; and 5) financial barriers may limit PPP-CCM scale-up and sustainability. Conclusion: PPP-CCM is a novel and promising approach to HCV care delivery for PWID who may previously lack engagement in traditional care models, but careful attention needs to be paid to financial barriers to ensure scalability and sustainability.
