Osteoarthritis (OA) affects over 40% of adults aged over 45 years, and more than 80% of over 65s. 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 due to lost productivity and other indirect financial costs in 2010. In total, that is over $500 per New Zealander, per year, or around 1.2% of GDP. Helping to manage the burden of OA is especially important for the future in which we will see the proportion of people over 65 increase to 1/4 of the population by 2040, while the proportion of people over 85 will quadruple.

These projects respond to a key health and disability challenge: Cost-effective, sustainable solutions are urgently required to get better value from healthcare spending on musculoskeletal conditions, particularly OA.

With an international, multi-disciplinary team of experts, Dr Abbott will investigate the clinical effectiveness and cost-effectiveness of clinical decisions in managing OA in linked, high-quality, funded clinical trials, in three different countries (NZ, Australia, USA).
