Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
First Arm: Post-Operative Management according to one pathway which facilitates patient recovery after total joint arthroplasty (TJA) through a mixture of pre surgical teaching and post surgical physiotherapy. It will involve heath professionals including orthopedics surgeons, nurses, physiotherapists and occupational therapists. Specific details have been omitted to preserve study blinding; these have been provided to the ANZCTR staff (via the Private notes) and will be published here once the trial has been completed.

Second Arm: Post-Operative Management according to a second pathway which facilitates patient recovery after total joint arthroplasty (TJA) through a mixture of pre surgical teaching and post surgical physiotherapy. It will involve heath professionals including orthopedics surgeons, nurses, physiotherapists and occupational therapists. This is different to the previous Intervention pathway, as there is some difference between the timing of certain elements of care provided.

Outcomes
Primary outcome [1] 297104 0
Length of hospital stay between the two arms of the study. This is assessed by using the hospital admission system and a review of the patient's medical record.
Timepoint [1] 297104 0
Length of hospital stay between the two arms of the study. The length of stay is from the end of the procedure to the hospital discharge.
Secondary outcome [1] 320027 0
Additional post operative complications, The post operative outcomes that we will be assessing are as follows. Deep venous thrombosis (DVT) or pulmonary embolism (PE) Superficial incisional surgical site infection Prosthetic joint infection Other Health Care Associated Infection Clostridium difficile infection Blood stream infection (BSI) including central-line associated BSI Pneumonia including ventilator-associated pneumonia Urinary tract infection (UTI) including catheter associated UTI Decubitus ulcer infection Post-operative delirium Postoperative acute urinary retention Postoperative pressure ulcer Postoperative acute kidney injury Postoperative cardiac complications; acute myocardial infarction or arrhythmia requiring treatment Clinically or radiologically confirmed atelectasis These are assessed based on medical record reviews from the patients stay in hospital. The Clinical Outcomes Clinical Outcome's Assessment questionnaire will also be administered, which has been designed by the research team for this study, to capture any post operative complications. Any information provided will be verified by medical record review.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be concealed. Allocation involved phone dial in to a central randomization service by the study coordinator, which occurs once the patient had been approached and consented by the study coordinator.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
At an individual patient level in a 1:1 ratio, stratified in blocks dependent on whether the patient is undergoing hip or knee replacement. Randomisation of participants to treatment arms will be coordinated by a dial-in, voice-response system with concealed allocation.
We are using computer randomisation service provided by the NHMRC Clinical Trials Centre

Statistical methods / analysis
The primary statistical analysis will be an intent-to-treat analysis on the entire sample. There will also be additional statistical tests to determine the cost-effectiveness of the intervention and to evaluate the success of the blinding of the intervention
The sample size estimate for this trial is 35 participants per study arm (total n =70 participants) based on the following parameters: average length of stay of 5.5 days (standard deviation 2.5) drawn from the St Vincent's Arthroplasty Outcomes Registry Data (SMART Registry); an estimated 2.3 day reduction in LOS based on the lower limit of the 95% confidence rate reported by Larsen et al (2008) a comparable randomized controlled trial, power of 80%; an alpha value of 5%. To allow for a loss to follow up rate of 10% this trial will recruit 80 participants in total.

Data sharing statement
Will the study consider sharing individual participant data?
No
No IPD sharing reason/comment: The database contains sensitive and private data from patients, and from the health professionals that were involved in their care. There is sensitive medical and health data (from patients) and medical decision and physical assessment data (from surgeons, physiotherapists, occupational therapists, nurses etc). This data is private and therefore will not be made available. There is no level of de-identification that would entirely remove identifiable markers from the data to prevent identification for either surgeon and patient
