Cost effectiveness of a community based exercise programme in over 65 year olds: cluster randomised trial.
OBJECTIVE
To assess the cost effectiveness of a community based exercise programme as a population wide public health intervention for older adults.


METHODS
Pragmatic, cluster randomised community intervention trial.


METHODS
12 general practices in Sheffield; four randomly selected as intervention populations, and eight as control populations.


METHODS
All those aged 65 and over in the least active four fifths of the population responding to a baseline survey. There were 2283 eligible participants from intervention practices and 4137 from control practices.


METHODS
Eligible subjects were invited to free locally held exercise classes, made available for two years.


METHODS
All cause and exercise related cause specific mortality and hospital service use at two years, and health status assessed at baseline, one, and two years using the SF-36. A cost utility analysis was also undertaken.


RESULTS
Twenty six per cent of the eligible intervention practice population attended one or more exercise sessions. There were no significant differences in mortality rates, survival times, or admissions. After adjusting for baseline characteristics, patients in intervention practices had a lower decline in health status, although this reached significance only for the energy dimension and two composite scores (p<0.05). The incremental average QALY gain of 0.011 per person in the intervention population resulted in an incremental cost per QALY ratio of 17 174 (95% CI = 8300 to 87 120).


CONCLUSIONS
Despite a low level of adherence to the exercise programme, there were significant gains in health related quality of life. The programme was more cost effective than many existing medical interventions, and would be practical for primary care commissioning agencies to implement.
