Study type
Interventional
Description of intervention(s) / exposure
A 6-month supervised: health professional-directed frailty program encompassing exercise, nutrition, medication optimisation and social connectedness, with telephone health coach support (to set goals with participants, tailor behaviour-change strategies, review progress and motivate participation, plus web-based frailty information and resources to support self-management,

Participants in this group will receive:
- A personalised telehealth dietetics appointment to develop a unique nutrition plan - 1 appointment at program initiation, delivered by a registered dietitian lasting up to 60 minutes. Adherence will be monitored and supported by a health coach
- Twice-weekly in-person progressive resistance training with a qualified exercise professional (exercise physiologist or physiotherapist with relevant training provided by our team). The exercise intervention will be delivered one-on-one with intensity and weight determined for each participant individually (example exercises: squats, tricep dips, plantar flexion). Sessions will last approximately 30 minutes, with balance training prescribed at home (4 days per week, 30 minutes).
- Health coaching to remain on track with all four pillars (exercise, nutrition, medication optimisation and social engagement. Participants will be entitled to up to 11 health coaching calls over the 6 months, starting at 4x weekly, then 4x fortnightly, then 3x monthly. Each session will last up to 60 minutes. Health coaches will have an allied health background and prior health coaching training and experience. Additional training will be provided, if needed, by our health coach coordinator.
- Medication optimisation will occur through a purpose-built website where participants will complete activities to uncover their goals of care (related to their medications), make a list of the medications they are currently taking, and be instructed to visit their GP to help align their medications with their goals. Participants only need to do this once, at the beginning of their program, and it will take approx. 30 - 60 mins. Adherence will be supported by the health coach.
- Social engagement will consist of three components (1) inviting a 'buddy' to participate in components of the program will them, (2) attending group-based health coaching sessions, once per month, will other intervention group participants, delivered online, and (3) having access to a range of community activities and events to increase their social connectivity. These activities will be displayed on our fittest website and available for everyone to view. There is no minimum engagement for this component as it is determined by the needs of the participants and will be supported by the health coach during regular sessions.

Our web-based frailty information is derived from the Asia Pacific Clinical Frailty Guidelines, but all materials have been specifically created for this study. Adherence to the intervention will be assessed by investigating the proportion of dietetics appointments attended, the proportion of exercise sessions attended, and the number of health coaching calls conducted.

Comparator / control treatment
A 6-month self-directed program with web-based frailty information and resources to support self-management.

The online content will provide a comprehensive overview of:
- Exercise: background of importance of weight bearing training on frailty, comprehensive overview of all exercises to be performed with factsheets and instructional videos.
- Nutrition: background of importance of protein and vitamin D on frailty, a nutrition self-assessment and targeted dietary changes
- Medications: background of importance of medication optimisation on frailty, goals-based assessment linking medications with goals, and instructions to discuss medications with GP
Social engagement: background on importance of social engagement on frailty and other health behaviours, importance of having a support person in this trial, and links to community programs that can assist with engagement.

Content will be presented mostly statically and through videos (exercise content). While there is no minimum engagement required from participants, meeting all our recommendations would mean they are engaging in the program for approximately 30 minutes per day. Participants will be provided with a target exercise schedule to meet, and engagement with the website will be monitored through web-portal analytics.

Statistical methods / analysis
With a sample of 195 in each intervention group, we would have 90% power for detecting a 0.03 unit change in the frailty index. This is based on a two-sample t-test with a common standard deviation of 0.075 (Theou et al, 2017), a two-sided alpha level of 0.05 and 30% attrition of participants where 0.03 frailty index units is the minimally important difference (Theou et al, 2020), and the average reduction in a pilot study aimed at reducing frailty in primary care (Theou et al, 2017),

Summary
Brief summary
The purpose of the study is to understand whether a supervised or a self-directed frailty program can slow frailty in older adults. We know that building muscle strength, eating a balanced diet and checking medications is best for healthy aging. We also know that being social or connecting with others can help improve or maintain quality of life. Both the supervised and self-directed programs are based on current clinical guidelines and best practice and include help with things we know can help slow or reduce frailty - exercise, diet, checking medicines, and social support and engagement. The study will also look at how easy these programs would be to put into practice in the real world, and to assess the cost of doing so. This study will be conducted in most states of Australia with a total of 390 participants Australia-wide.
