Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
New allied health weekend service developed following focus group interviews with health professionals (medical, nursing and allied health) on each ward to identify the most appropriate distribution of funds to different allied health professions. Services will include physiotherapy, occupational therapy, social work, nutrition and speech pathology weekend allied health service delivery. Services delivered are the same as those done on weekdays, although the intensity of weekend services is lower (fewer hours per ward) than weekday services. Services may include mobilization, chest physiotherapy, discharge planning, assessment and prescription of aids and equipment, swallowing assessment, dietary analysis and prescription, and counselling.
The duration of this intervention is 6 months: the new model of
weekend allied health service delivery will be rolled-out across 6 acute medical and surgical units one-by-one on a monthly basis.
Intervention code [1] 288271 0
Other interventions
Comparator / control treatment
No weekend allied health service delivery. The duration of this
intervention is 7 months, as it includes one month with no weekend services in any of the 6 trial wards, plus the 6 months of gradual roll-out of new services.
Control group
Active

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
As this is a stepped-wedge cluster RCT, patients will not be individually randomised. Extensive consultation with the managers and clinicians at participating sites has resulted in a list of wards agreeing to participate in this trial. Placement of each ward into the ward number location will be determined at random by an investigator blinded to ward identity.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
One investigator will develop pseudonyms for each ward involved in the study. Another investigator, blinded to the true identity of each pseudonym, will use a random number generator in Microsoft Excel to allocate ward number locations to each pseudonym. The first investigator will then be able to reveal which pseudonym represented which ward.

Other design features
The design of this trial is a roll-out stepped wedge cluster randomised trial.

Qualitative outcomes:
A small, cross-disciplinary group of health professionals (4-6 per ward) will be sought to describe the impact that changing
the model of weekend allied health service has had on staff workload and patient care during the trial. This information will be collected at group-interviews. interviews will be conducted with staff members from each ward prior to the trial, and again at the post-trial timepoint. The aim is to explore their satisfaction with and experiences of the different weekend allied health service delivery models. We will also explore differing workplace pressures both during the weekend and on working days experienced under the different models, and also
workers' perspectives on and response to being involved in a research program undertaken with a disinvestment focus.

Statistical methods / analysis
Stepped-wedge cluster RCT: Linear mixed model analyses will be used to construct the 95% confidence intervals that compare effectiveness and safety outcomes between groups. These models will nest patients within wards, treating both as random factors, to account for the clustered nature of this data. “Weekend allied health service delivery model provided” will be treated as a fixed factor. Data distributions will be examined (+/- transformations as indicated) as a part of model building. Data from patients who are exposed to both control and intervention conditions within each phase will be excluded from the analyses. Superiority analyses will be conducted. Interim analyses will be conducted as monthly outcome data becomes available. Data will be analysed at a site-specific level (relevant to this specific trial registration) and in a pre-planned meta-analysis across 6 studies (including this one) being conducted as a part of this research program.
The economic analysis will be a cost-effectiveness analysis from the hospital perspective that examines the incremental cost per patient treated. These costs will include the “total cost” of patients during their admission plus additional costs from an unplanned admission within 28 days. The primary analysis will examine data from all patients, while a secondary analysis will focus on patients present on a weekend. Data from patients who are transferred between wards in different study periods (ie. one without access to allied health services, one with access to allied health services) will be excluded from the analyses as will data
from patients who remain within the same ward over two or more weekends if they are allowed to access weekend allied health services during one weekend, and not allowed to access allied health services on another.

A framework approach will be used for the analysis of qualitative data collected as a part of this study.

The sample size in this study is governed by the patient through-put of the participating wards over the trial period. Current data from study wards indicates there will be approximately 7308 patients in total.

We used the approach for conducting power analyses for stepped
wedge trials advocated by Hussey and Hughes based upon the Wald statistic. Using this approach, this trial has 96% power, given a 0.03 absolute increase (10% relative increase) non-inferiority margin from 0.30 (40%) for the proportion of patients who exceed their diagnosis specific “inlier” average length of stay.
