It is estimated that in Australia physical inactivity contributes to 13 500 annual deaths and incurs an annual cost of AU 21 billion to the health care system. The cost of physical inactivity to the Western Australian WA economy is estimated to be about AU 2.1 billion. Increased burden of physical inactivity has motivated health professionals to seek cost effective intervention to promote physical activity. One such strategy is encouraging general practitioners GPs to advocate physical activity to the patients who are at high risk of developing chronic diseases associated with physical inactivity. This study intends to investigate the cost-effectiveness of a subsidy program for GP advice to promote physical activity. Methodology The percentage of population that could potentially move from insufficiently active to sufficiently active on GP advice was drawn from the Western Australian WA Premier s Physical Activity Taskforce PATF survey in 2006. Population impact fractions PIF for diseases attributable to physical inactivity together with disability adjusted life years DALYs and health care expenditure were used to estimate the net cost of intervention for varying subsidies. Cost-effectiveness of subsidy programs were evaluated in terms of cost per DALY saved at different compliance rates. Results With a 50 adherence to GP advice an annual health care cost of AU 24 million could be potentially saved to the WA economy. A DALY can be saved at a cost of AU 11 000 with a AU 25 subsidy at a 50 compliance rate. Cost .
