| Annotation | The cost-effectiveness of four different lifestyle interventions for knee pain were estimated, using cost utility analysis of randomised controlled trial. Participants were 389 adults aged 45+ with self-reported knee pain and body mass index (BMI) of 28 or more from 7 UK general practices. The four interventions used were: dietary intervention plus quadriceps strengthening exercises; dietary intervention; quadriceps strengthening exercises; and leaflet provision. Participants received home visits over a 2-year period. Advice leaflets were associated with a mean change in cost of -£31 and mean quality adjusted life year (QALY) gain of 0.085. Both strengthening exercises and dietary interventions were more effective (0.890 and 0.133 mean QALY gain, respectively) but were less cost effective. Dietary intervention plus strengthening exercises had a mean cost of £647 and a mean QALY gain of 0.147 and was estimated to have an incremental cost of £19,489 per QALY gain (relative to leaflet provision) and a 23.1% probability of being cost effective at a £20,000 QALY threshold. Dietary intervention plus strengthening exercises was estimated to be cost effective for individuals with knee pain, but with a large level of uncertainty. (RH). |
