Pharmacists' Interventions in Virtual Diabetes Clinics: Cost-Effectiveness Feasibility Study

Background: Telepharmacy, the provision of patient care services by pharmacists through the use of telecommunications technology, is associated with improved diabetes-related outcomes and access to healthcare. The primary aim of this study was to characterize pharmacists' interventions at a virtual pharmacist-led diabetes clinic (PLDC). The secondary aim was to assess the feasibility of conducting a future cost-effectiveness study of the PLDCs. Methods: This prospective observational feasibility study was conducted within a pharmacist-led clinic at Seha Virtual Hospital, Riyadh, Saudi Arabia. Two intern pharmacists collected data between 31 July 2024 and 31 January 2025. Results: Seventy-five patients (mean [SD] age 50.47 years [14.95]) attended the clinic. The majority were female (58.7%), had type 2 diabetes (86.6%), and were from outside Riyadh (97.3%). The communication with patients was carried out mainly via telephone (73, 97.3%). The mean consultation duration was 7.64 min (SD = 5.68). A total of 179 interventions were conducted, with a mean number of interventions per patient of 2.5 (median 3, min 0, max 5). The most common intervention was patient education and counseling about their disease and medications. While it was feasible to capture the details of pharmacist interventions and resource use data, incomplete data on patient outcomes presented a challenge. Conclusions: Our detailed documentation of pharmacist-patient encounters revealed the ability of pharmacists to identify and manage the problems of diabetes patients at virtual PLDCs. Our feasibility study identified a few challenges that need to be addressed when designing future cost-effectiveness studies.
