Effective UK weight management services for adults
A number of evidence-based weight management interventions are now available with different models, and serving different patient/client groups. While positive outcomes are key to the decision making process, so too is the information around how these outcomes were achieved, in what population, how transferable the outcomes would be to the population a service would be aiming to cover and at what cost to the service-provider and or the individual. This paper examines all the UK interventions with recent peer-reviewed evidence of their effectiveness in “realistic” settings and cost-effectiveness, in the context of NICE and SIGN guidelines. It concludes that the evidence-based approaches allow intervention at different stages in the disease-process of obesity which are effective in different settings. Self-referral to commercial agencies, by individuals with relatively low BMI and few medical complications is a reasonable first step. For more severely obese individuals (e.g. BMI >35kg/m2) requiring more medically complicated care, evidence is largely lacking for these services, but the community-based Counterweight Programme is effective and cost-effective in maintaining weight loss >5kg up to 2 years for 30-40% of attenders. For more complicated and resistant obesity, referral to a secondary care-based service can generate short-term weight loss, but 12 months data are unavailable
Long-term cost-effectiveness of weight management in primary care
Background: As obesity prevalence and health-care costs increase, Health Care providers must prevent and manage obesity cost-effectively. Methods: Using the 2006 NICE obesity health economic model, a primary care weight management programme ( Counterweight) was analysed, evaluating costs and outcomes associated with weight gain for three obesity-related conditions ( type 2 diabetes, coronary heart disease, colon cancer). Sensitivity analyses examined different scenarios of weight loss and background ( untreated) weight gain. Results: Mean weight changes in Counterweight attenders was -3 kg and -2.3 kg at 12 and 24 months, both 4 kg below the expected 1 kg/year background weight gain. Counterweight delivery cost was 59.83 pound per patient entered. Even assuming dropouts/non-attenders at 12 months (55%) lost no weight and gained at the background rate, Counterweight was 'dominant' (cost-saving) under 'base-case scenario', where 12-month achieved weight loss was entirely regained over the next 2 years, returning to the expected background weight gain of 1 kg/year. Quality-adjusted Life-Year cost was 2017 pound where background weight gain was limited to 0.5 kg/year, and 2651 pound at 0.3 kg/year. Under a 'best-case scenario', where weights of 12-month-attenders were assumed thereafter to rise at the background rate, 4 kg below non-intervention trajectory ( very close to the observed weight change), Counterweight remained 'dominant' with background weight gains 1 kg, 0.5 kg or 0.3 kg/year. Conclusion: Weight management for obesity in primary care is highly cost-effective even considering only three clinical consequences. Reduced healthcare resources use could offset the total cost of providing the Counterweight Programme, as well as bringing multiple health and Quality of Life benefits
