Evaluation of a pharmacist-led, 6-month weight loss program in obese patients

To evaluate a pharmacist-led weight loss program based on the general requirements set forth by the Centers for Medicare & Medicaid Services' (CMS) Decision Memo for Intensive Behavioral Therapy for Obesity.

Onsite Walgreens pharmacy located inside the main administration building of Maricopa County in downtown Phoenix, AZ.

A prevention and wellness behavioral therapy weight loss program was developed for patients of the Maricopa County on-site Walgreens.

Current pharmacy patients were recruited to attend 14 one-on-one, pharmacist-led, face-to-face behavioral therapy sessions during a 6-month period that addressed diet, exercise, and nutrition. Interactive PowerPoint presentations were used throughout the sessions.

The primary outcome was mean weight loss from baseline to the end of the study. Secondary outcomes included changes in body composition, changes in nutritional intake, and participant satisfaction.

Of 12 enrolled participants, 11 (92%) completed the program. The mean weight loss from baseline to the end of the program was 5 kg (P <0.001), representing an average 4.5% weight loss. There was a statistically significant decrease in body mass index (BMI), waist circumference, and percent visceral fat from baseline to the end of the study; however, the increase in percent muscle mass, decrease in percent body fat, and change in nutrition intake was not statistically significant. Overall, the participants rated the program highly.

Pharmacists are accessible health care providers who can effectively provide intensive behavioral therapy for obesity in a manner consistent with the CMS guidelines.
