Trajectories of Long-Term Residential Care Needs Among Older Australian Women: A Cohort Study Using Linked Data

Do health assessments affect time to permanent residential aged care admission for older women with and without dementia?

AIM

To investigate the effect of health assessments on permanent residential aged care admission for older Australian women with and without dementia.

METHODS

A total of 1427 older Australian women who had a health assessment between March 2002 and December 2013 were matched with 1427 women who did not have a health assessment in the same period. Linked administrative datasets were used to identify health assessment use, admission to permanent residential aged care, and dementia status. Outcome was time to residential aged care admission from the matched date of health assessment.

RESULTS

Women who had health assessments were less likely to be admitted to residential aged care in the short term (100 days), irrespective of dementia status (subdistribution hazard ratio [SDHR] = 0.35, 95% CI = [0.21, 0.59] for women with dementia; SDHR = 0.39, 95% CI = [0.25, 0.61] for women without dementia). However, there were no significant differences at 500- and 1000-days follow-up. At 2000-days follow-up, women who had a health assessment were more likely to be admitted to residential aged care, regardless of dementia status (SDHR = 1.41, 95% CI = [1.12, 1.79] for women with dementia; SDHR = 1.55, 95% CI = [1.32, 1.82] for women without dementia).

CONCLUSIONS

Benefits from health assessments may depend on the recency of the assessment, with women less likely to be admitted to residential aged care in the short term after a health assessment. Our results add to a growing body of literature suggesting that health assessments may provide benefits to older people, including those with dementia. Geriatr Gerontol Int 2023; 23: 595-602.

Effect of Dementia on Outcomes After Surgically Treated Hip Fracture in Older Adults

BACKGROUND

Hip fractures are associated with increased mortality and functional limitations. However, the effect that dementia has on these outcomes in individuals in aged care settings after fracture is not well established. This study examined the association of dementia with post-hip fracture mortality, permanent residential aged care entry, transition care use, and change in activities of daily living (ADL) needs.

METHODS

A retrospective cohort study using data from the Registry of Senior Australians (2003-2015) was conducted. Individuals with a hip fracture while receiving aged care services were included. Associations of dementia with mortality, risks of transition and permanent care use, and ADL needs progression were estimated using multivariable Cox, Fine-Gray, and logistic regression methods, respectively.

RESULTS

Of 4771 individuals evaluated, 76% were women, the median age was 86 years (IQR 82-90), and 71% already lived in permanent residential aged care at the time of fracture. Within two years of their hip fracture, 50.4% (95% CI 48.9%-51.8%) of individuals died, 16.2% (95% CI 14.2%-18.2%) entered a transition care program, 59.1% (95% CI 56.5%-61.7%) entered permanent residential aged care, and 32% had greater ADL needs. Dementia was associated with higher risk of two-year mortality (HR = 1.19, 95% CI 1.09-1.30), 90-day entry into permanent care (sHR = 1.96, 95% CI 1.60-2.38), and increased likelihood of ADL limitations (OR = 1.36, 95% CI 1.00-1.85). Minor differences were seen in transition care use by dementia status.

CONCLUSION

Dementia is a strong risk factor for mortality after hip fractures in individuals in aged care settings and associated with a high risk of entry into permanent care.

Housing and Care for Older Women in Australia

Background: Housing is essential for healthy ageing, being a source of shelter, purpose, and identity. As people age, and with diminishing physical and mental capacity, they become increasingly dependent on external supports from others and from their environment. In this paper we look at changes in housing across later life, with a focus on the relationship between housing and women's care needs.

Methods: Data from 12,432 women in the 1921–26 cohort of the Australian Longitudinal Study on Women's Health were used to examine the interaction between housing and aged care service use across later life.

Results: We found that there were no differences in access to home and community care according to housing type, but women living in an apartment and those in a retirement village/hostel were more likely to have an aged care assessment and had a faster rate of admission to institutional residential aged care than women living in a house. The odds of having an aged care assessment were also higher if women were older at baseline, required help with daily activities, reported a fall, were admitted to hospital in the last 12 months, had been diagnosed or treated for a stroke in the last 3 years, or had multiple comorbidities. On average, women received few services in the 24 months prior to admission to institutional residential aged care, indicating a potential need to improve the reach of these services.

Discussion: We find that coincident with changes in functional capacities and abilities, women make changes to their housing, sometimes moving from a house to an apartment, or to a village. For some, increasing needs in later life are associated with the need to move from the community into institutional residential aged care. However, before moving into care, many women will use community services and these may in turn delay the need to leave their homes and move to an institutional setting. We identify a need to increase the use of community services to delay the admission to institutional residential aged care.

The effect of frailty on outcomes of surgically treated hip fractures in older people

BACKGROUND

Hip fractures are associated with mortality, disability, and loss of independence in older adults. While several risk factors associated with poor outcomes following a hip fracture have been identified, the effect of frailty status prior to hip fracture is not well established.

AIM

To examine the associations of frailty with mortality, change in activities of daily living (ADL) limitations, and transition to permanent residential aged care in older people following a hip fracture.

METHODS

A retrospective cohort study was conducted on people aged 65 years and older with a surgically treated hip fracture between 2003 and 2015. Frailty was estimated using a cumulative deficit-based frailty index and categorized into quartiles. Cox multivariable regression, logistic regression, and Fine-Gray multivariable regression models estimated associations of frailty with mortality, ADL limitations, and entry into permanent residential aged care, respectively. Hazard ratios (HR), odds ratios (OR), subdistribution hazard ratios (SHR), and 95% confidence intervals (95%CI) are reported.

RESULTS

Out of 4771 individuals with hip fractures, 75.6% were female and the median age was 86 (interquartile range 82-90) years old. The two-year survival of patients following hip fracture was 43.7% (95%CI 40.9-46.7%) in those in the highest quartile of frailty, compared to 54.4% (95%CI 51.8-57.2%) for those in the lowest quartile (HR = 1.25, 95%CI 1.11-1.41, p < 0.001). No associations between pre-fracture frailty and post-fracture ADL limitations were observed. Additionally, no association of frailty with transition to permanent residential aged care for patients living in the community (n = 1361) was observed (SHR = 0.98, 95%CI 0.81-1.18, p = 1.000).

CONCLUSIONS

Older patients with the highest level of frailty had an increased risk of mortality after hip fracture. Consideration for appropriate clinical interventions, including fall and frailty prevention measures, may be appropriate for this identified group of vulnerable individuals.
