Study Details

Knee and hip osteoarthritis are among the most common causes of pain and disability in older adults. Total annual healthcare costs attributable to OA in New Zealand – estimated to be $555M in 2010 – are rising rapidly as the population ages. Accompanying this is an increasing disability burden on society, estimated to be around $2.1B of lost productivity and other indirect financial costs in 2010. Cost-effective, sustainable solutions are urgently required to get better value from healthcare spending on OA.

This study was an economic evaluation conducted alongside the MOA Trial: a randomized, controlled trial (RCT) designed to investigate the benefits and costs of physiotherapy for improving pain and physical function in people with OA of the hip or knee. The findings of the trial are therefore presented not only in terms of health outcomes and quality of life gains, but also in terms of economic savings to the healthcare system, society, taxpayers and the individual.
