Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Geriatricians will review: comorbid conditions and optimisation of management in advance of surgery; review of medications and plan for management in the perioperative period; goals and limits of care and advance care plans; assessment of cognition and plan to minimise risk of delirium in the perioperative period; anticipating change in function and associated care needs at home in advance of the surgical procedure; discharge planning in advance of the procedure; and Comprehensive Geriatric Assessment.
Duration of the review: 45min to 1 hour
Frequency: one consultation and follow-up as determined by the geriatrician
Geriatric consultation will take place prior to patients' surgery

Physiotherapist will provide home exercises. The first exercise session will be conducted by the study physiotherapist at Liverpool hospital. The first exercise session will be approximately 40-60minutes in duration depending on participants. The study physiotherapist will conduct telehealth twice per week for 3 weeks (for a total of 2 telehealth sessions per week) to monitor participant’s progress in exercise program and adjust the intensity of the training according to participant’s reported perceived exertion (RPE) and symptoms if need.
All participants will be provided with exercise diary which includes images of exercises to be conducted, log of completion of exercises (day and specific exercises) and breathing exercises

An example of exercise prescription:
5-10 minutes of warm up and cool down
Aerobic training (mainly walking, steps and cycle)
Frequency: 3 times per week, 30 minutes per session
Resistance training: light to moderate 10-15 repetitions involving 6-8 groups of skeletal muscles, at least twice a week, using resistance bands

Summary
Brief summary
Four in five (80%) older Australians report having one or more long-term health condition. Older frail patients who undergo cardiac surgery have poorer postoperative outcomes.
There is some evidence that multidisciplinary prehabilitation may reduce the number of postoperative complications in older patients undergoing abdominal cancer surgery.
There is a need for the current pilot study to demonstrate the feasibility of the multidisciplinary prehabilitation program in frail older persons and to investigate any potential risk, adverse events, compliance to exercise program and satisfaction in this patient population who has higher likelihood of unwanted postoperative outcome after cardiac surgery.
