IMPROVE-65 is a randomised control trial designed specifically for people aged over 65 who have survived critical illness. It aims to support patients and general practitioners by providing timely, personalised information to help them work together to make informed goals and decisions about their care after hospital discharge. The aim of the study is to improve recovery and avoid preventable hospital readmissions.

Critical illness and intensive care unit (ICU) admissions represent significant life events that carry substantial risks for long-term health consequences. An estimated 50% of Australians will be admitted to ICU during their lifetime, placing them at considerable risk of new or worsened physical, cognitive, and psychological dysfunction following discharge. Among ICU patients, those aged 65 years and older constitute the majority, accounting for 52.5% of all admissions. Older adults experience disproportionately higher burdens of illness severity, frailty, and comorbidities, which complicate both the management of acute critical illness and the subsequent recovery process. These factors contribute to longer ICU and hospital stays, increased mortality, and a heightened risk of long-term disability. Previous research shows that nearly 40% of Australian ICU patients aged over 65 years are living with significant disability six months after discharge. Despite the growing number of ICU survivors and the known risks of long-term morbidity, there is currently no formal or standardised system of follow-up care in Australia to monitor or support recovery. Survivors of critical illness have frequently reported fragmented transitions from hospital to home, poor communication between tertiary and primary care providers, and insufficient support to prevent or manage new disability. General practitioners (GPs), often the primary source of ongoing care, have similarly identified a lack of communication and the absence of prioritised discharge summaries as barriers to effective post-ICU care. Building on these insights, previous work has explored innovative models of care to support functional recovery. This includes care navigation to reduce avoidable hospitalisations among high-risk patients, digital tools to improve communication between hospital and primary care, and technology-enabled goal-setting to facilitate rehabilitation. These initiatives demonstrate the potential for digital and telehealth approaches to bridge existing gaps in care continuity and patient-centred recovery. This trial will determine if a multifaceted recovery navigated approach to coordinate and deliver timely and individualised post hospital care and recovery goals, will reduce the burden of new disability at 3 months following discharge from hospital after critical illness. Additionally, the trial will review the cost effectiveness at 6 months after randomisation. By enabling more effective communication between ICU survivors and their GPs, improving access to health information, and promoting shared decision-making, IMPROVE-65 aims to enhance the quality of survivorship, reduce new disability, and minimise healthcare costs and avoidable hospital readmissions for critically ill older adults.
