Use of health and aged care services in Australia following hospital admission for myocardial infarction, stroke or heart failure

Abstract

Background Cardiovascular diseases (CVD), including myocardial infarction (MI), stroke and heart failure (HF) are the leading cause of death amongst the older population worldwide. The aim of this study is to investigate trajectories of use of health and aged care services after hospital admission for MI, stroke or HF among community-dwelling people not previously receiving aged care services. Methods The study population comprised people aged 65+ years from the 45 and Up Study with linked records for hospital stays, aged care services and deaths for the period 2006–14. Among those with an index hospital admission for MI, stroke or HF, we developed Sankey plots to describe and visualize sequences and trajectories of service use (none, re-hospitalization, community care, residential care, death) in the 12 months following discharge. We used Cox proportional hazards models to estimate hazard ratios (HRs), for commencing community care and entering residential care (and the other outcomes) within 3, 6 and 12 months, compared to a matched group without MI, stroke or HF. Results Two thousand six hundred thirty-nine, two thousand five hundred and two thousand eight hundred seventy-three people had an index hospitalization for MI, stroke and HF, respectively. Within 3 months of hospital discharge, 16, 32 and 29%, respectively, commenced community care (multivariable-adjusted HRs: 1.26 (95%CI:1.18–1.35), 1.53 (95%CI:1.44–1.64) and 1.39 (95%CI:1.32–1.48)); and 7, 18 and 14%, respectively, entered residential care (HRs: 1.25 (95%CI:1.12–1.41), 2.65 (95%CI:2.42–2.91) and 1.50 (95%CI:1.37–1.65)). Likewise, 26, 15 and 28%, respectively, were rehospitalized within 3 months following discharge (multivariable-adjusted HRs: 4.78 (95%CI:4.31–5.32), 3.26 (95%CI:2.91–3.65) and 4.94 (95%CI:4.47–5.46)). Conclusions Older people hospitalized for major CVD may be vulnerable to transition-related risks and have poor health trajectories, thus emphasizing the value of preventing such events and care strategies targeted towards this at-risk group.

“…Therefore, early identification of individuals with high-risk factors will provide an opportunity for the early intervention and prevention of MACE in these individuals. Stratifying patients according to risk of future outcomes and optimizing treatment strategies can help reduce their follow-up costs and mortality ( 7 – 9 ).…”

“…Therefore, the early identification of individuals with high risk factors in the community will give chance to the early intervention and prevention of early adverse effects for those individuals. Therefore, it will reduce their late-stage health care costs and mortality rate ( 8 , 9 ).…”
