Background To describe the impact of long COVID on disability, function and quality of life among adults living in Australia. Method People aged >18years with a history of COVID-19 infection confirmed by polymerase chain reaction or rapid antigen test were eligible for this cross-sectional survey. The World Health Organization Disability Assessment Schedule 2.0 measured disability and function, and the 36-Item Short Form Health Survey assessed quality of life. Results Participants (n =121) reported significant functional impairment and reduced quality of life compared with established population norms for these outcome measures. Most (n =104, 86%) reported clinically significant disability and participation limitations in daily activities. Mean World Health Organization Disability Assessment Schedule 2.0 scores indicated higher levels of disability than 98% of the general population. The 36-Item Short Form Health Survey scores indicated lower quality of life across all domains, but particularly in relation to vitality and social functioning. Regression analysis found significant associations between the World Health Organization Disability Assessment Schedule 2.0 and 36-Item Short Form Health Survey scores, and vaccine dose number, comorbidities and self-rated recovery. Conclusion Long COVID is associated with significantly reduced function and quality of life, which are distinct outcomes requiring targeted assessment and intervention. The overall impact may be exacerbated in people with pre-existing comorbidities who are more susceptible to long COVID in the first place. The findings underscore the need for targeted rehabilitation and support services for people living in Australia with long COVID, and further longitudinal research to explore the long-term impact on disability and quality of life, and inform policy and healthcare service delivery.
