Arthritis and musculoskeletal conditions are large contributors to illness, pain and disability in Australia, according to a report released today by the Australian Institute of Health and Welfare (AIHW) and launched by Minister for Ageing the Hon. Julie Bishop.
The report, Arthritis and musculoskeletal conditions in Australia, is the first of its kind, designed to generate national baseline information on the subject.
Report co-author Dr Naila Rahman, from the AIHW's National Centre for Monitoring Arthritis and Musculoskeletal Conditions, said that around 6.1 million Australians are estimated to have arthritis or a musculoskeletal condition, and almost one in five of them say they have activity limitations associated with their condition.
'In addition to pain, restricted mobility is the most commonly reported symptom. Limitations on activities of daily living include going out of the house, getting in and out of bed, and performing many household chores,' Dr Rahman said.
The effects of rheumatoid arthritis and osteoarthritis can be insidious.
'A large number of joint replacements in Australia, in particular knee and hip replacements are due to osteoarthritis. Joint replacements increased from almost 30,000 procedures in 1997-98 to close to 40,000 in 2003-04, and this number is likely to increase as the population ages,' said report co-author Dr Kuldeep Bhatia.
Costs associated with long-term treatment and management of arthritis and musculoskeletal conditions accounted for the third largest component of health expenditure in Australia in 2000-01, with an estimated expenditure of $4.6 billion.
Report co-author, Ms Elizabeth Penm, said those costs are likely to increase for several reasons.
'Not only are surgical procedures on the rise, but more effective yet costly prescription drugs such as COX-2 inhibitors and biologic response modifiers have been introduced over the last several years. So we're likely to continue to see higher costs in this area.'
'The news is not all bad though,' Dr Rahman added. 'Many people disabled by arthritis can be treated. Technological innovations like assistive devices, and residential and occupational modifications, should all help to improve the opportunities for independent living.'
