Hip fractures are common, especially in older adults, and they can have a big impact on health and quality of life. In Australia, hip fractures are a significant healthcare challenge. After surgery, patients often need rehabilitation to regain mobility, but this usually involves long hospital stays. The RITH4Hips trial will determine if a program where patients receive rehabilitation at home (instead of in the hospital) is similar to conventional inpatient rehabilitation.
Objectives:
The main goal of this study is to find out if rehabilitation at home after surgery for a hip fracture works as well as rehabilitation in the hospital. The investigators also want to see if the home rehabilitation program can reduce the time spent in a hospital bed and improve other aspects like quality of life, mobility, and pain management.
Methods:
This study will involve older adults who have had surgery due to a low-trauma hip fracture. Participants will be randomly assigned to either the usual care inpatient rehabilitation or the Rehabilitation in the Home (RITH) program. The investigators will measure outcomes such as how well patients can move, how much pain they experience, how their quality of life improves, and how much time they spend in the hospital.
Expected Outcomes:
The investigators expect that the home rehabilitation program will be just similar to inpatient rehabilitation in helping patients recover mobility. The investigators also hope to find that it will reduce the time patients spend in a hospital bed, improve their quality of life, reduce fear of falling, and lessen the burden on carers. Additionally, the investigators aim to show that the home program is more cost-effective than hospital-based rehabilitation.
Study Aim This study aims to determine whether a multidisciplinary Rehabilitation in the Home (RITH) program for patients following low-trauma hip fracture (LTHF) is non-inferior to inpatient rehabilitation in terms of mobility during activities of daily living (ADL), assessed using the de Morton Mobility Index (DEMMI)
Study Design This is a pragmatic, multicentre, randomised, single-blinded, parallel-group, non-inferiority clinical trial with an embedded qualitative component.
As part of recruitment monitoring, reasons for declining participation will be recorded for individuals approached but not enrolled.
Hypotheses
The investigators hypothesise that compared to inpatient rehabilitation, the RITH program will be:
Non-inferior in terms of mobility recovery (DEMMI score within 2.9 points). Superior in reducing hospital bed days, with at least a 6-day reduction in physical ward stay.
Superior in improving health-related quality of life, walking ability, fear of falling, opioid consumption, and carer experience.
More cost-effective than usual care. Effective in reducing total length of stay (LOS), provided barriers to rapid transition to RITH are addressed.
Methods
Eligibility is determined perioperatively.
Inclusion criteria
Once cleared for rehabilitation (typically 5-10 days post-surgery), participants will be randomised to:
Intervention Groups
Usual Care Inpatient Rehabilitation (UCIR): Participants will receive care in a rehabilitation ward or subacute hospital, including therapy from a multidisciplinary team. Discharge occurs when they achieve sufficient walking and functional ability, typically within 1-3 weeks. Researchers will collect information about carer visits and associated costs during the stay.
Rehabilitation in the Home (RITH): Participants will receive therapy at home from a multidisciplinary team. Discharge occurs when they achieve sufficient walking and functional ability, typically within 1-3 weeks. Researchers will contact patients about carer-related costs during the program.
Follow-up Assessments:
After completing rehabilitation, researchers will visit participants at home (or in the clinic if preferred) shortly after discharge and again six weeks after their initial hospital admission to assess walking ability, daily activities, confidence, quality of life, pain, and post-surgery challenges. Researchers will also gather information on healthcare visits, costs, and new community services used. If participants have carers, the carers will be invited to complete a voluntary survey about carer experience. Medical records will also be reviewed to understand the care provided over the study period.
Qualitative study:
A purposive sample of patients and their carers who were randomised to the RITH group will be invited to participate in a one-on-one interview some weeks after completing rehabilitation. Additionally, an opportunistic sample of other stakeholders such as clinicians, healthcare managers, and insurers will be invited to participate. The embedded qualitative study seeks to gain insights into why the RITH program was or was not deemed effective for individual participants, as well as how the RITH program may be made more acceptable for future implementation.
Sample size calculation:
A sample of 220 participants (allowing for 7% loss to follow-up) is required to detect:
A 2.9-point between-group difference in DEMMI (non-inferiority margin: 6, SD: 8.9).
A 6-day reduction in hospital bed days (mean 25, SD 17, negative binomial parameter theta = 2.1) with 80% power (α = 0.05).
Analysis plan for primary outcome: The primary outcome will be analysed using an analysis of covariance (ANCOVA) with the 6-week DEMMI score as the dependent variable, and independent variables of group, timepoint, and an interaction between group and timepoint. The 6-week DEMMI will be examined using contrasts of the interaction.
Cost analysis: A cost-effectiveness analysis will be conducted alongside this trial, including both direct and indirect costs.
Analysis plan for qualitative study: Qualitative interviews will be analysed using the Rapid Assessment Process, combining deductive and inductive approaches for efficient thematic analysis.

|---|---|---|---|---|
| Rehabilitation in the home | Other | Participants will receive home-based therapy from a MDT team, including physiotherapists, occupational therapists, social workers, dietitians, medical practitioners, psychologists, and pharmacists. Participants will be transferred to RITH once they achieve a level of mobility (+/- assistance) that enables them to manage at home. As per usual care, the disciplines required, frequency of visits, duration of visits, and duration of rehabilitation will be based on the patient's specific needs. There will be weekly MDT conferences to discuss patient progress led by medical staff. Telehealth care may be incorporated into the RITH program, subject to patient preference and provider availability. If the participant deteriorates during the RITH program, the escalation plan mandated by the LHD HITH Department will be followed to ensure appropriate care is provided. As for UCIR, discharge occurs when patients achieve sufficient walking and functional ability with available assistance. |
| Measure | Description | Time Frame |
|---|---|---|
| De Morton Mobility Index (DEMMI) | The De Morton Mobility Index is a mobility outcome measure specifically designed for an older population. The DEMMI assesses 15 tasks which are associated with activities of daily living such as bed mobility and sit-to-stand transitions. The DEMMI is scored between 0 - 100, where 0 represents no mobility and 100 represents full mobility. The Minimal Clinically Important Difference (MCID) for the DEMMI is estimated to be approximately 6 points, representing the smallest change necessary to reflect a clinically meaningful improvement in mobility. | At 1 to 3 days following discharge from the rehabilitation program (an average of 14 days after admission to rehabilitation) and at 6 weeks after initial admission. |
| Measure | Description | Time Frame |
|---|---|---|
| Length of Stay (LOS) - Total | Number of days spent in the program, from acute admission until discharge from rehabilitation. | At 1 to 3 days following discharge from the rehabilitation program (an average of 14 days after admission to rehabilitation). |
| Length of Stay (LOS) - Physical Ward Bed |
| Measure | Description | Time Frame |
|---|---|---|
| Quality-Adjusted Life Years (QALYs) | QALYs will be derived from responses to the EQ-5D questionnaire administered at three timepoints: baseline (prior to randomisation), 1 to 3 days after discharge from the rehabilitation program, and 6 weeks post-admission. This measure will quantify patient health outcomes and quality of life over time, enabling the evaluation of the RITH program's impact on patient well-being. |

The assessor and statistician will be blinded to randomisation outcomes and will perform assessments on all participants from both arms. Assessments will be conducted at two time points: at the completion of the program (UCIR or RITH) and at six weeks following initial hospital admission. This blinding minimises potential bias in outcome evaluation and ensures the integrity, reliability, and objectivity of the trial's findings.
|
| Usual care inpatient rehabilitation | Other | Participants will receive care in a rehabilitation ward or subacute hospital, including therapy from a MDT team. Discharge occurs when patients achieve sufficient walking and functional ability with available assistance, typically within 1-3 weeks, though this varies. |
|
Number of days spent in a physical ward bed in the hospital (including both acute and subacute locations). |
| At 1 to 3 days following discharge from the rehabilitation program (an average of 14 days after admission to rehabilitation). |
| Index Hip Pain | Hip pain at rest, on movement, and maximum. Score is a numerical rating from 0 - 10, where 0 is no pain and 10 is the worst pain imaginable. | Assessments will occur at baseline (within 24 hours prior to randomisation), daily during the allocated rehabilitation program (an average of 14 days from admission to rehabilitation), and at 6 weeks following initial hospital admission. |
| EuroQol-5D-5L (EQ5D) | The EuroQol-5D-5L is a questionnaire used to measure patient's health-related quality of life. It assesses 5 domains related to mobility, self-care, usual activities, pain/discomfort and anxiety/depression and provides a score between 1 - 5 for each domain where 1 means no problems, and 5 means extreme problems. | Assessments will be conducted at baseline (within 24 hours prior to randomisation), at 1 to 3 days following discharge from the rehabilitation program (an average of 14 days after admission to rehabilitation), and at 6 weeks post-admission. |
| Timed Up-and-Go Test (TUG Test) | The Timed Up-and-Go Test measures the time required for a patient to stand from a seated position and walk three meters at a comfortable pace using any required mobility aids, before returning to a seated position. The TUG Test is a good indicator of overall mobility and fall risk, however, it will only be used on patients deemed capable of safely conducting this test. | At 1 to 3 days following discharge from the rehabilitation program (an average of 14 days after admission to rehabilitation) and at 6 weeks after initial admission. |
| Falls Efficacy Scale (FES) | The Falls Efficacy Scale is a 10-item questionnaire used to assess a patient's fear of falling during various activities of daily living. Each item is scored between 1 - 10, where 1 means very confident with this activity, and 10 means not confident at all with this activity. Higher scores indicate a higher fear of falling. | At 1 to 3 days following discharge from the rehabilitation program (an average of 14 days after admission to rehabilitation) and at 6 weeks after initial admission. |
| Zarit Carer Burden Interview (ZCBI) | The short-form Zarit Carer Burden Interview assesses the physical, emotional, social, and financial burden associated with being a caregiver. Each item is assigned a score from 0 - 4, where 0 means never and 4 means nearly always. Higher total scores are associated with increased carer burden. | At 1 to 3 days following discharge from the rehabilitation program (an average of 14 days after admission to rehabilitation). |
| Positive Aspects of Caregiving Scale (PACS) | The Positive Aspects of Caregiving Scale assesses the perceived benefits experienced by caregivers as a result of their role. The PACS is designed to balance to conventionally negatively-skewed burden assessments by instead focusing on domains related to personal growth and relationship satisfaction. The PACS uses a scale of 1 - 5 for each item where 1 means strongly disagree and 5 means strongly agree. Higher total scores are associated with more positive caregiving experiences. | At 1 to 3 days following discharge from the rehabilitation program (an average of 14 days after admission to rehabilitation). |
| Functional Independence Measure (FIM) | The Functional Independence Measure (FIM) is a routinely used outcome measure in inpatient rehabilitation to assess a patient's level of disability and need for assistance with activities of daily living. It consists of 18 items, each scored on a 1-7 scale, where 1 indicates total assistance required and 7 signifies complete independence. Higher total scores reflect greater overall functional independence. | At 1 to 3 days following discharge from the rehabilitation program (an average of 14 days after admission to rehabilitation) and at 6 weeks after initial admission. |
| Hospital-Acquired Complications (HACs) | The rate and types of Hospital-Acquired Complications (HACs) will be recorded at the end of the program, with definitions aligned to the Australian Commission on Safety and Quality in Health Care (https://www.safetyandquality.gov.au/our-work/indicators-measurement-and-reporting/hospital-acquired-complications-hacs). Additionally, regular safety monitoring of adverse events will be conducted throughout the program. | At 1 to 3 days following discharge from the rehabilitation program (an average of 14 days after admission to rehabilitation). |
| Assessments will be calculated at 6 weeks post-admission. |
| Health Service Costs | The total episode of care cost to the health service will be assessed from the provider's perspective. Episode of care costs will be obtained directly from the hospital, while direct costs for each episode of care and episode of service will be sourced from the health service. All costs will be adjusted to 2025 values using the Gross Domestic Price Index. | Health service costs will be assessed using data from each hospital's Finance Department, covering admission to the end of the allocated rehabilitation program (average 14 days post-rehab admission). Data will be available 8 to 12 weeks post-discharge. |
| Participant and Carer Costs | Participant and carer costs will be collected through regular follow-ups and will include expenses such as costs for parking, transportation, home modifications, medication, and lost productivity due to time taken off work. These costs will capture the financial burden on both participants and their carers as part of the economic evaluation of the RITH program. | Assessments will occur weekly during the allocated rehabilitation program (up to average 14 days from rehabilitation admission), and at 6 weeks following initial hospital admission. |
| Incremental Cost-Effectiveness Ratio (ICER) | The ICER will be calculated as the cost per additional Quality-Adjusted Life Year (QALY) gained, comparing the health service cost and participant and carer costs of the RITH and UCIR programs. This measure will assess the cost-effectiveness of the RITH program by evaluating the economic impact relative to improvements in patient health outcomes. | Assessments will be calculated at 6 weeks following initial hospital admission. |
| Opioid Consumption | Opioid consumption throughout the program duration will be recorded in oral morphine equivalent daily dose (OMEDD), using the opioid calculator developed by the Faculty of Pain Medicine, Australian and New Zealand College of Anaesthetists. Additionally, opioid use at 6 weeks post-admission will be measured as a yes/no outcome. For participants reporting continued opioid use at 6 weeks, the frequency and reason for use will also be recorded. | Assessments will occur daily through completion of the allocated rehabilitation program, starting on Day 1 and continuing until discharge (on an average duration of 14 days), and at 6 weeks following initial hospital admission. |
