Surgical teams look after an increasing number of older people. Geriatric co-management models of care to non-orthopaedic surgical teams have not been well studied. This binational survey determined what geriatric co-management services are in place across acute hospitals in Australia and New Zealand, and examined the geriatricians’ views on future directions. Survey responses from n=67 (83%) of the n=81 identified Geriatric Medicine departments were received. The majority (96%) of departments provided a traditional reactive consult service for non-orthopaedic surgical patients. Only 12 (18%) had a geriatric co-management service in place. Across these 12 services, the most common features were regular geriatrics ward rounds (100%), attendance at multidisciplinary meetings (83%), and medication review (92%). These liaison services provided care for a number of surgical specialities: colorectal (n=8), general surgery (n=7), upper gastrointestinal (n=7), trauma (n=4), vascular (n=4), urological (n=2), cardiothoracic (n=1), and neurosurgery (n=1). All 67 respondents thought there was a need for geriatric medicine as a specialty to provide greater input into the care of older surgical patients. Vascular (52%) and colorectal surgery (15%) were identified as having the greatest need for geriatric medicine input. Respondents identified lack of funding (88%) and not enough geriatricians (58%) as the major barriers. Although geriatric medicine departments across Australia and New Zealand believe they need to provide collaborative care for older surgical patients, only a few hospitals currently have co-management services in place. There is a need to establish funding for these services and further research to determine the best models of care.
