The impact of dietitians on better health outcomes for those with Musculoskeletal conditions
Dietary intervention has been shown to be cost effective for overweight band obese adults with knee pain (Barton et al 2009).
Dietary intervention plus strengthening exercises had a mean cost of £647 and a mean quality of life years (QALY) gain of 0.147 and was estimated to have an incremental cost of £10469 per QALY gain (relative to leaflet provision), and a 23.1% probability of being cost effective at a £20,000/QALY threshold in an evaluation of lifestyle interventions for knee pain in overweight and obese adults.
