Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Name of intervention: Allied health assistant provision of routine post-operative hip fracture rehabilitation
Who will deliver the intervention and what is their training: The intervention will be delivered by a senior allied health assistant (grade 3). The allied health assistant will have a certificate IV allied health assistant qualification. A senior (grade 3) acute orthopaedic physiotherapist will supervise the senior allied health assistant as per health network clinical supervision guidelines. This supervision will include monthly meetings to discuss professional and clinical skill development in the management of people recovering from hip fracture. It will also involve direct supervision/observation of the senior allied health assistant’s management of people recovering from hip fracture.
Mode of delivery: Individual, face-to-face
Dose: Daily therapy provided on weekdays (i.e. daily therapy 5x per week) until discharge from acute hospital. Initial physiotherapy assessment may occur on a Saturday if hip fracture surgery performed on a Friday. The duration of each session will vary dependent on patient needs.
Location/Timing: All therapy will be provided to patients recovering from hip fracture surgery on the orthopaedic ward at Frankston Hospital. Therapy will be provided by the allied health assistant following an initial post-operative physiotherapy assessment of the patient. The allied health assistant will be delegated provision of routine post-operative hip fracture rehabilitation if the patient is transferred to sitting out of bed during the physiotherapy assessment and appropriate for mobilisation (walking). This process will involve the physiotherapist completing an initial assessment and providing a thorough handover to the allied health assistant.
Procedures and personalisation: Routine acute rehabilitation of patients with hip fracture should include daily mobilisation (i.e. walking) as per Australian and New Zealand Hip Fracture Registry Guidelines and may also include:
1) progression of gait aid
2) standing/seated exercises (e.g. squats, sit-to-stand, calf raises)
3) education (e.g. falls risk strategies)
All therapy will be prescribed by the physiotherapist who conducts the initial assessment and tailored to the individual needs of the patient and the therapy will be implementd by the allied health assistant. As per standard protocol, following treatment of the patient with hip fracture the allied health assistant will inform the physiotherapist, who completed the initial assessment, of the details of the session and the patient’s progress in their ability to mobilise. The physiotherapist will use this feedback to determine the discharge plan and re-assess the patient as required.
Fidelity: The fidelity of the intervention will be determined by measuring the time and occasions of service each patient spends with i) the physiotherapist and ii) the allied health assistant.

Comparator / control treatment
Name of comparator treatment: Physiotherapy provision of routine post-operative hip fracture rehabilitation
Who will deliver the intervention and what is their training: The intervention will be delivered by accredited and practising physiotherapists
Mode of delivery: Individual, face-to-face
Dose: One to 5x per week therapy until discharge from acute hospital. Initial physiotherapy assessment may occur on a Saturday if hip fracture surgery performed on a Friday. The duration of session will vary dependent on patient needs.
Location/Timing: All therapy will be provided to patients recovering from hip fracture surgery on the orthopaedic ward at Frankston Hospital. Therapy will be provided by the physiotherapist following their initial post-operative assessment of the patient.
Procedures and Personalisation: Routine acute rehabilitation of patients with hip fracture should include daily mobilisation (i.e. walking) as per Australian and New Zealand Hip Fracture Registry Guidelines and may also include:
1) progression of gait aid
2) standing/seated exercises (e.g. squats, sit-to-stand, calf raises)
3) education (e.g. falls risk strategies)
All therapy will be tailored to the individual needs of the patient Allied health assistants may assist the therapist to mobilise a patient who requires the assistance of two people but will not be delegated the role of providing daily mobilisation or rehabilitation.
Fidelity: The fidelity of the comparator treatment will be determined by measuring the time and occasions of service each patient spends with i) the physiotherapist and ii) the allied health assistant.

Feasibility: Acceptability Domain (Primary Outcome)
Acceptability domain will be evaluated by measuring patient satisfaction with physiotherapy care. Patient satisfaction with physiotherapy care will be measured using a modified version of a questionnaire for hospital inpatients receiving inpatient orthopaedic physiotherapy care. The original version of the questionnaire has been validated for use in an inpatient orthopaedic population by Ampiah and colleagues (2019). The patient rates their agreement with each statement on a 5-point Likert scale ranging from 1 (strongly agree) to 5 (strongly disagree). For the purpose of this study we will use a modified version with six of the items removed. The items related to financial cost of physiotherapy care, diagnosis, time from physiotherapy referral to assessment, equipment available to the physiotherapist/assistant and compliance with physiotherapy will be removed from the questionnaire.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be determined by email or phone contact with an independent researcher after the member of the research team has determined eligibility for the study, participants have consented to take part, and baseline assessment has been completed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomly allocated to the experimental (allied health assistant care) or control (physiotherapy care) group using simple randomisation. Participants will be randomly assigned remotely using simple randomisation design with a computer random number generator prepared by an independent researcher not involved in the screening process, or collection of data.

Statistical methods / analysis
Quantitative data analysis:
Descriptive statistics will be used to describe the characteristics of the sample by group (means [SD], percentages and frequencies) as well as patient satisfaction, time physiotherapist/allied health assistant spends with patient, cost of physiotherapy service/patient care and adverse events.

Compliance with daily mobilisation guidelines will be collected in the form of time-to-event data, and mobilisation rate ratios will be calculated using Cox proportional hazards regression to directly compare mobilisation rates in the intervention and control (comparison) conditions.

As patients can have multiple mobilisations, and are not eligible for subsequent mobilisation until initial mobilisation has occurred, recurrent event data will be analysed via the Williams and Peterson Gap time survival model, with robust standard errors to account for correlation within patients.

In the survival analyses, discharge will be considered a censoring event. This equates to an assumption that data regarding mobilisation on days following discharge are missing at random (given timing of discharge). The appropriateness of this assumption will be checked in sensitivity analyses. No interim analyses will be conducted.

Length of stay will be analysed using survival analysis (time-to-discharge) with death as a competing risk.

Functional activity will be analysed using t-tests.

Dichotomous outcomes include discharge destination (home vs. residential care), 30-day re-admission (30-day re-admission vs. no re-admission) and faller (fall vs. no falls) will be analysed with logistic regression.

Sample Size:
We aim to recruit 50 participants. While there are no clear guidelines on the sample size required for feasibility studies this size should enable the primary aim of feasibility to be addressed.

Qualitative data analysis:
Interviews will be audiotaped and records of all interviews will be transcribed. Any identifying information will be removed and each transcript assigned a number for further analysis.

Qualitative analysis of transcripts will be undertaken by two investigators independently, using qualitative data management software. The de-identified transcripts will be read by each investigator and codes devised to represent the data. Codes will be reviewed and emerging themes will be developed through a process of collapsing codes together and defining categories, using an interpretive descriptive approach. Consensus between the investigators on the emerging themes and categories will be achieved through discussion.
Following the interview, each participant will be sent a copy of their transcript for correction, clarification and further comment, to maximize accuracy of the data (a process termed ‘member checking’). All identifying information in the transcript will be removed following member checking.

Summary
Brief summary
This randomised controlled trial will investigate the feasibility of an allied health assistant providing physiotherapy to people following hip fracture surgery. The allied health assistant will provide all therapy to people in hospital. All therapy will be prescribed by a physiotherapist and will include daily walking, and standing and seated exercises. We hypothesise that it is feasible for allied health assistants to provide physiotherapy to people after hip fracture surgery.
