OBJECTIVES: Impacts of patient psychosocial and behavioral factors on weight management programs are not well studied. The current study examined the relationship between patient engagement and weight management in a pharmacist-led clinic within a managed care organization.
METHODS: This IRB-approved study employed retrospective and prospective (survey) design, incorporating patients consistently enrolled in the weight management clinic for ≥3 months. Deidentified patient data from 2015 to 2024 were examined to assess changes in weight, A1C, and LDL. A 24-item survey was designed to assess patient engagement, provider and program satisfaction on a 4-point agreement scale. Following face and content validation, surveys were administered via telephone to eligible participants. Data analysis included descriptive statistics, survey validation, comparison and correlation analyses.
RESULTS: Among 733 eligible patients, survey responders (n=166) were primarily female, White, with age 56.7±14.4, some college education, annual household income ($51-100K), and private insurance. Non-responders (n=567) were significantly younger, had fewer chronic conditions and shorter clinic duration. Scale reliability was high at Cronbach’s alpha of 0.96. Factor analysis revealed most items loading (0.48 to 0.82) onto hypothesized domains with 3-4 items in the engagement domain falling out of line. About 69.3% responders used a GLP-1RA for weight loss, while 8.4% not on any weight loss medication reported significantly lower satisfaction (3.13±0.12 vs. 3.58±0.07, p<0.05). Regression revealed 11-pound weight loss with each 1-point increase in engagement, and 9-pound weight loss with satisfaction (p<0.01), controlling for baseline weight, condition count, medication duration, and clinic duration. No association was noted between patient-reported and clinical outcomes.
CONCLUSIONS: The study showed positive correlations between engagement level, program satisfaction and weight loss. Weight management programs could focus on interventions such as consistent support and a personalized plan to improve patient engagement.
