Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Standard preoperative care plus prehabilitation is defined as:
1. Delivery of standard preoperative care
2. Face-to-face (FTF) review within 3-6 months of planned surgery, to confirm and assess:
a. Sarcopaenia: grip strength, 30 second sit-to-stand (STS), timed-up-and-go (TUG), and the de Morton Mobility Index (DEMMI)
b. Nutrition screening via malnutrition screening tool (MST). If screen positive, further malnutrition classification using the 7-point Subjective Global Assessment (SGA), lean muscle mass, body mass index (BMI_ and serum albumin and transthyretin levels
c. Smoking status Y/N. If screen positive, further smoking classification using the Heaviness of Smoking Index (HSI).
3. Intervention is dependent on the above findings:
a. All patients will undergo a targeted sarcopaenia program. This program will be delivered individually. This consists of an initial 60 minute FTF physiotherapy review. The patient will be assessed by the physiotherapist using the revised BORG RPE (Borg rating of perceived exertion) scale aiming for an exercise intensity of 3 (moderate) and allocated to 2x ability-adjusted exercise programs focusing on cardiovascular and strength exercises. Patients will complete 4 x 30 minute sessions per week. Some of the exercises in the cardiovascular program include getting in and out of bed, walking, marching on the spot, punching the air and steps ups. Some of the exercises in the strength program include heel raises, knee extensions, hip flexion, shoulder press, bicep curls and upright row. Education on safe completion of the program, progression through the program and measurement of adherence via mobile phone app is provided during this session. The app being used has been designed specifically for this study and is called "Monash Prehab".
b. The exercise program will continue via a tele-health supported, home-based exercise program over the course of 12 weeks with 3x telehealth delivered physiotherapy sessions at weeks 2, 4, 8. The sessions will assess adherence to the program, ongoing education as required, progression of exercises as required and sessions 15-30 minutes in duration.

Comparator / control treatment
Standard preoperative care is defined as:
• Completion of a digital patient health questionnaire occurs upon completion of a request for elective admission (REA) for surgery. The remaining assessments occur within 3-6 months prior to planned surgical date.
• Triage by orthopaedic perioperative liaison nurses (PLNs),
• Standard preadmission clinic review with surgeon, anaesthetist, pharmacist and nurse within 4 weeks of planned surgical date,
• Standard investigations include a 12 lead electrocardiogram (ECG) (within 1 year of surgery), baseline pathology (full blood count, renal function, anaemia screening, haemoglobin A1C (HbA1C) if diabetic).

Statistical methods / analysis
This is a pilot study assessing feasibility in a two armed trial. It is reasonable to apply published “rules of thumb” as a determination of appropriate sample size. As such, a sample size of 50 patients in total, or 25 patients in the sarcopaenia intervention and 25 patients in the control group, will give sufficient precision in adherence rates and outcome rates for the design of a future definitive trial. Sample sizes for both the nutritional and smoking cessation pathways will be lower and as such, data gathered in these interventions will be exploratory.

Data will be analysed using SPSS for Windows version 29 (SPSS Australasia Ltd. Sydney).
Demographic and perioperative data will be presented as mean (SD) or number (%) for categorical variables, or median and interquartile ranges (IQRs) for continuous variables.
Associations will be analysed using Spearman rank correlation and a p-value of <0.05 will be considered significant.
