Implementation of a pharmacist-led weight loss service to improve medication access and weight loss

Background: Obesity is a prevalent medical condition that can contribute to an increased risk of developing serious comorbidities, leading to an increase in hospitalizations, morbidity, and mortality. Many of these medical conditions can be improved with weight loss. Objectives: This project was designed to improve weight loss outcomes and assess the utilization of services provided by clinical pharmacists for collaborative weight loss management. Methods: The study design was a single-center, retrospective, and quality improvement study within 3 outpatient clinics at Tufts Medical Center. Patients referred to the pharmacist-led weight loss service from September 1 to October 31, 2022, and continued care for up to 6 months were included. Pharmacist services included selection of weight loss medication, assistance with medication access, device teaching and dose titration, lifestyle counseling, and follow-up. The primary outcome was percent weight loss from baseline. Results: Seventy-nine patients were referred to the pharmacist-led weight loss service. Mean age of patients was 51 years (SD +/- 13). Sixty-one patients were female (77.2%). Median baseline weight was 105.5 kg (IQR 93.1 to 120.5 kg) and body mass index 38.1 kg/m(2) (IQR 33.9 to 43.5 kg/m(2)). The median percent weight loss from baseline through the end of the study duration was similar to (IQR -3.1 to similar to 12.1%). Conclusion: Pharmacists were able to effectively provide weight loss care through a pharmacist-led weight loss service by aiding in medication access, providing education on devices and lifestyle management, and engaging in frequent follow-up. Future directions of this study include expansion of the pharmacist-led weight loss service to other ambulatory care clinics within TMC. (c) 2024 American Pharmacists Association (R).
