The Counterweight Project • Evidence-based model for obesity management • Evaluated in primary care • Competency based training and mentoring • Clinically significant, cost effective • Ongoing programme enhancement using continuous improvement methodology
The Counterweight Project • Project board includes 7 national opinion leaders on obesity • Specialist team of 12 dietitians/nutritionists facilitate programme implementation • Independant evaluation team for data analysis and statistics
Intervention • BMI ≥ 30 or 28 kg/m2 with co-morbidity • 6 appointments /group sessions over 3 months • 10-30 min appointments /1 hr group sessions • Weight loss maintenance • Quarterly review then annual • Aim minimum of 25 patients/year per practice J Hum NutrDietet. 2004; 17: 191-208

Original evaluation 2002-2005 • 56 practices • 1906 patients • Mean BMI 37kg/m2 • Mean age 49 years • 77% patients female • 25% patients had BMI ≥ 40kg/m2 • 74% patients had ≥ 1 co-morbidity Br J Gen Pract. 2008; 58: 548-554

Used model developed for National Institute for Health and Clinical Excellence (NICE, 2006) Considers impact of the 12 month observed outcomes of the Counterweight Programme Assume no impact on the non-attending 55% Scenarios considered: Base case: weight lost is regained over the next two years Best case: weight loss is maintained over the individual’s life Both of these then revert to 1 kg/year usual weight gain in obese population Counterweight cost effectiveness
Illustration of scenarios X = Baseline. Y= 12 months with Counterweight intervention Base case scenario = Regain all 4 kg weight difference effect in 2 yrs Best case scenario = Life-long maintenance of 4 kg weight difference No intervention - gain 1kg/y X Base case scenario Best case scenario Observed 2-year mean weight loss -2.3 kg (from baseline) Y International Journal of Clinical Practice (2010); 64(6), 775-783
Even based on very limited estimates of the costs of obesity, and conservative benefit of Counterweight linked to DM, CHD, colon cancer the programme is highly cost-effective for UK NHS In the medium-long term, providing Counterweight in routine Primary Care will lead to cost savings from reduced medical consequences of obesity Health economic summary International Journal of Clinical Practice (2010); 64(6), 775-783
Project to established practice • Scottish Government funding from 2006 • Implementation in 3 waves 2006-2008 • Waves 1, 2 implemented alongside Keep Well (CVD risk reduction)

Motivators for programme adoption • Government policy and political drive • Engagement with primary care, obesity strategic teams, public health, dietetics • Dovetail with established local programmes • Link with clinical problems • Feedback of outcomes Family Practice In Press
Conclusion The Counterweight Programme continues to demonstrate consistent outcomes in UK primary care
