Health status and healthcare trends of individuals accessing Australian aged care programmes over a decade: the Registry of Senior Australians historical cohort.

BACKGROUND

Understanding the health profile, service and medicine use of Australians in the aged care sector will help inform appropriate service provision for our ageing population.

AIMS

To examine the 2006-2015 trends in (i) comorbidities and frailty of individuals accessing aged care, and (ii) health services, medicine use and mortality after entry into long-term care.

METHODS

Cross-sectional and population-based trend analyses were conducted using the Registry of Senior Australians.

RESULTS

From 2006 to 2015, 509 944 individuals accessed permanent residential care, 206 394 home care, 283 014 respite and 124 943 transition care. Over this time, the proportion of individuals accessing permanent residential care with high frailty scores (≥0.3) increased (19.7-49.7%), as did the proportion with 5-9 comorbidities (46.4-54.5%), with similar trends observed for those accessing other services. The median number of medicines dispensed in the year after entering permanent residential care increased from 9 (interquartile range (IQR) 6-12) to 10 (IQR 7-14), while remaining stable in home care (2006: 9, IQR 5-12, 2015: 9, IQR 6-13). Short-term (within 100 days) mortality in those accessing permanent care was higher in 2006 (15.6%, 95% CI 15.2-16.0) than 2015 (14.6%, 95% CI 14.3-14.9). Longer term (101-1095 days, 2006: 44.3%, 95% CI 43.7-45.0, 2015: 46.4%, 95% CI 45.8-46.9) mortality was higher in 2015 compared to 2006. Mortality in individuals accessing home care did not change.

CONCLUSION

The health of older Australians accessing aged care programmes has declined while frailty increased, with an increasing use of medicine and worse long-term mortality in some. Funding and care models need to adapt to this changing profile.
