A Service Evaluation of a Specialist Multi-Disciplinary Weight Management Service Based in Primary Care Including Long-Term Follow-Up Data.

This service evaluation of a primary care-based specialist weight management service reports data from 1094 patients over 5 years (2014-2019), including weight data at 1-year post-discharge. The results show clinically and statistically significant improvements in weight, diet, physical activity, quality of life, blood pressure and blood glucose control (in people living with type 2 diabetes). Change in weight was statistically significant for all timepoints in all subgroups. At 1-year completers (n = 560) had lost a mean of 8.3 kg (SD 0.3) and 133 patients (23.8%) had lost ≥ 10% of their starting weight. Using baseline observation carried forward analysis on the whole cohort (n = 1094) the mean weight loss at the end of the 1-year programme was 4.5 kg (SD 0.2) and 144 (13.2%) had lost ≥ 10% of their starting weight. A year after discharge completers demonstrated a mean weight loss of 8.3% (SD 10.3 n = 303) and 35.6% (n = 108) of completers had maintained ≥ 10% change in body weight. Analysis showed a mean weight loss of 2.5% (SD 6.8 n = 1094) in the whole cohort using baseline observation carried forward, demonstrating maintenance of weight loss and suggesting that specialist weight management services in primary care may be effective in the longer-term.
