Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A frailty management plan will be devised while the participant is in hospital based on the FRAIL scale score. It will be a personalised intervention strategy that may include targeted physical exercises, dietary supplements and de-prescribing of poly-pharmacy. It will differ from participant to participant according to individual need. There will be facilitation and support of this intervention upon discharge from hospital by a community implementation facilitator. Participants will be discharged home with a set of exercises tailored to their needs. Some will have supplements or have been prescribed a high energy/high protein diet. They will be asked to do the exercises daily (or as often as possible) and to document when they have done so on a calendar. Similarly they will be asked to self report on their adherence to any dietary recommendations. The community facilitator will visit the participant only once or twice, but will also engage with the GP as it is expected the GP will encourage and support the participant with the frailty management plan in the community going forward.

The intervention strategy is prescribed on the ward (jointly) by the Physiotherapist (exercise program), the Dietician (appropriate dietary intervention) and the Pharmacist (poly pharmacy) dependent on the participant needs as highlighted in the FRAIL Scale. The Implementation Clinician, assists with ensuring adherence to the intervention while the participant is in hospital and the Community Implementation Facilitator will engages with the participant and the GP in the community.

The overall duration of the intervention is 12 months from date of recruitment with outcome assessments at 3 months and at 12 months.

The first community facilitator visit will occur as soon as practicable following discharge at a date and time mutually agreed upon between the facilitator and the participant. There may be up to two further visits, depending on need. If a subsequent visit or visits are required these will occur at a time deemed most appropriate by the facilitator (ie - it may be based on a request by the participant, the GP or a significant other, or it may be arranged at the time of the first visit). There is flexibility around this, as it is thought that some participants will require more support than others to adhere to the management plan, and some participants have less home support than others. The nature of these visits will also depend on the individual but are about ensuring the management plan is transitioned smoothly into the community and participants are able to adhere to it at home. The facilitator will ensure exercises and dietary recommendations are being followed as prescribed and liaise back to the Implementation Clinicians (at the hospital) for adjustments or advice if necessary. They also will liaise with the GP to encourage support for the plan.

Rehabilitation
Comparator / control treatment
The study will use a hybrid type III trial approach which allows testing of the implementation strategy (Implementation Facilitation) at the same time as observing the outcomes of the intervention (screening for frailty and use of appropriate interventions). The study design will be a randomised stepped wedge design with interventions being commenced at FOUR-month intervals in six wards in two hospitals (one in NSW and one in SA). During the first four months all 6 participating wards will act as control wards with no interventions taking place. In the second 4-month period two of the wards will start receiving the intervention. In the third 4-month period 4 wards will receive the intervention, and in the final 4 months all six wards will be intervention wards. Those participants who are controls will receive 'usual care' which may well include physiotherapy and dietary components, however it will not be an intervention designed to specifically target frailty. All controls and interventions will be followed up in the community by a masked outcome assessor at 3 and 12 months post recruitment in hospital.

Eligibility
Key inclusion criteria
To be eligible to participate in the FORTRESS study people must:

1) be aged 75 years and over, with an estimated life expectancy of more than 12 months, estimated by a score 1 or 2 on a modified version of the Illness Severity Rating
2) have been admitted to an acute medical or rehabilitation ward in Hornsby Ku-ring-gai Hospital in northern Sydney, or Flinders Medical Centre in southern Adelaide
3) have been assessed as frail (using the FRAIL Scale Risk Assessment Tool) by the FORTRESS study Implementation Clinician (scored equal to or greater than 3 on this scale).
4) be living at home in the community prior to hospitalisation (ie they did not reside in an Aged Care Facility)
5) be able to cooperate with suggested interventions as assessed by the Implementation Clinician or other allied health staff (attain a score of 18 or more on the Mini Mental State Examination (MMSE)
Minimum age

Key exclusion criteria
Exclusion criteria for FORTRESS include:

1) People admitted to hospital with stroke. (People with acute stroke are admitted to specialised units in both participating hospitals).
2) People who are not frail or screen as pre-frail (a score of less than 3 on the FRAIL Scale)
3) People who are unable to cooperate with intervention program (cognitive impairment per se is not an exclusion criteria but older people with moderately severe dementia or a score of less than 18 in the Mini Mental State Examination (MMSE) may not be able to participate)
4) People aged less than 75 years of age
5) People who were not mobile prior to admission (unable to walk without the assistance of another person)
6) People with a life expectancy of less than 12 months, estimated by a score of 3 or more on a modified version of the Illness Severity Scale
7) People who reside in a residential aged care facility
8) People who have already been recruited into the study when admitted to another participating ward

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The ward randomisation allocation will be carried out by the FORTRESS study bio-statistician.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Transition to intervention phase will be randomised by ward with stratification by site and using minimisation with a random component to address the potential for baseline and sequential balance. An adaptation of a dynamic (adaptive) random allocation method such as minimisation will be used for sequence generation.

Efficacy
Statistical methods / analysis
The anticipated enrolment is approximately 732 participants from the six wards over 16 months allowing for approximately 10% drop out and 10% mortality, with this sample size we will be able to detect a difference between control and intervention conditions of 25% vs 15% readmissions at 3 months, and 50% vs 35% readmissions at 12 months using time to event analysis of readmission, with 80% power and 5% significance level, allowing for a design effect of 1.5.

It is anticipated that one third of the participants will be recruited from South Australia and approximately two thirds will be recruited from NSW.

The primary analyses with reference to non-elective hospital readmissions will be time to event analyses using a survival analysis approach. Readmissions will be adjudicated as non-elective / elective by an adjudication committee independent of the investigators.
The secondary analyses will use linear mixed models with adjustment for credible confounders including age, gender and cognitive status (noting that cognitive status is now routinely assessed at and during hospital admission to meet the National Safety and Quality Health Service Standards 2nd Edition).

The analyses will be supervised by the study statistician.
