Clinical Telepharmacy: Addressing Care Gaps in Diabetes Management for an Underserved Urban Population Using a Collaborative Care Model.

Introduction: Optimal chronic care management is limited by low health care access and health literacy among underserved populations. We introduced clinical pharmacy services to enhance our patient-centered home model, which serves mostly Medicare/Medicaid-insured patients. Primary care providers (PCP) refer patients with uncontrolled diabetes to the pharmacist for chronic disease management between PCP appointments to bring A1c to goal under a collaborative agreement. This workflow existed before the COVID-19 pandemic and was primarily in-person visits. Our model transitioned to telehealth, where pharmacy services continued via audio/video visits to avoid disruption in care. Methods: A collaborative scope of practice within care guidelines was developed with PCPs. Established patients with uncontrolled diabetes were referred to the clinical pharmacist. The workflow remained consistent through January 1, 2019 to January 31, 2020 (pre-COVID), and April 1, 2020 to October 31, 2021 (post-COVID). February and March 2020 were excluded due to changing operational processes at the pandemic onset. The pharmacist independently saw patients for medication-related interventions and ordered associated labs within the scope of practice. The program was retrospectively evaluated via process metrics (visit volume and intervention types) and clinical outcome (A1c reduction). Results: A total of 105 patients were referred for diabetes management during the study period. These were in-person pre-COVID (95%) and shifted to entirely audio/video (100%) post-COVID. Impact of pharmacy services was sustained through the change in care model: an A1c reduction of more than 0.5% was observed in 65% ( n  = 20) and 69% ( n  = 49) of patients managed by the pharmacist, pre- and post-COVID, respectively. Pharmacy visit volumes were 86 versus 308, respectively. Conclusion: Pharmacy referral and visit volumes increased over the pandemic, made possible via telehealth. The goal attainment rate observed pre-COVID was amplified even with the growth in services over time. Clinical pharmacy services delivered through audio/video telehealth visits may be equally effective compared to face-to-face services.
