Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study intervention involves a prospective feedback loop to clinical teams, based on the outcomes of a twice-weekly patient record review process using the Criteria for Screening and Triaging to Appropriate aLternative Care (CriSTAL) tool and the Supportive and Palliative Care Indicators Tool (SPICT). The feedback provided to the clinical teams (the CriSTAL status and SPICT score) is intended to act firstly as a flag for the clinical team to review patient care activities and pathways, and to stimulate a tailored clinical response to promote appropriate patient care and treatment outcomes.
The study will be implemented in three acute Queensland hospitals. All hospitals commence the study at the same time point, and all complete a four-week site preparation and clinical team recruitment phase. Hospital 1 then sequentially completes a 16 week usual exposure phase, a four-week intervention establishment phase and a 34-week intervention exposure phase; Hospital 2, a 25-week usual exposure phase, a four-week establishment phase and a 25-week intervention exposure phase; and Hospital 3, a 34-week usual exposure phase, a four-week establishment phase and a 16-week intervention exposure phase.
The four-week intervention establishment phase will be used to prepare for the implementation of the feedback loop intervention, and tailor it to ensure it is feasible at each site and reflects local context and workflows. In this phase the the project team, study team, hospital executive advisory group and enrolled clinical teams will work together to:
- attend information sessions about the study, the tools being used, the background and evidence for non-beneficial treatment including risk factors and the range of options for responding to screened patients. these will be delivered by the project team. Number and duration will be tailored to reflect hospital requirements; will minimally include a 30 minute introduction session and a 30 minute evidence and rationale session.
- decide the process for the study team to provide the patient level screening outcomes to the clinical teams:
- pilot the proposed feedback mechanisms for one week with each clinical team, in the intervention establishment phase.
- decide the preferred clinical team responses to feedback. This will require agreement on how each clinical team will respond to feedback about the screening outcomes and the hospital inputs that will be provided to support this. Clinician response plans could include, but will not be limited to, palliative care referral, multidisciplinary team review, advance care planning consultation, and patient/carer meetings.

The record review will be performed by a trained auditor, employed as a Registered Nurse at the participating hospital and not part of the participating clinical team. A member of the study team will provide direct feedback to a nominated clinical team member of the outcomes of each record review. The study team will conduct a process evaluation to assess adherence and fidelity and support implementation.
The record review will occur throughout the usual exposure, intervention establishment and intervention exposure phases, with the feedback of the screening scores to clinical teams and a tailored clinical response part of the intervention phase only.
There are three participant populations across the study:
1: Clinical teams - who will be enrolled in the study and participate in the feedback loop intervention
2: Patients 75 years and older, admitted under enrolled clinical teams
3: Members of the enrolled clinical teams, executive advisory group, site study team - who will be invited to participate in semi-structured interviews in the intervention establishment, intervention exposure and post-trial phases.

Behaviour
Comparator / control treatment
This is a stepped-wedge study design where each hospital and clinical team will act as their own control. Patient record review will occur throughout the study with the feedback loop and associated clinical response occurring in the intervention exposure phase. The length of the usual exposure and intervention exposure phases will be randomly allocated as per the stepped-wedge design for periods of 16, 25 or 34 weeks each.
During the usual exposure and intervention establishment phases all usual care will be provided by the clinical teams. Usual care in this case means the medical care that is typically provided by the clinical teams at the participating hospitals as part of their employment.
To check for potential seasonality or other confounders we will collect historical and comparator data about patient admission rates to the Intensive Care Unit (ICU) and length of hospital stay. These data will be collected for all patients 75 years and older admitted to TPCH, RBWH, GCUH in non-enrolled clinical teams, and three comparator hospitals, for 2 years prior to week 1 as well as for the trial period of the study.

Key exclusion criteria
Clinical team exclusion criteria:
Excluded clinical teams will be those from the emergency department, any Intensive Care Units (ICUs), mental health units, and non-acute care and teams that do not meet all the inclusion criteria. While inappropriate treatment can occur in the ICU setting, we are choosing to study the feedback intervention with clinical teams that care for patients before they go to ICU.
Clinical teams that are already implementing an intervention or initiatives related to reducing non-beneficial treatments for older patients will be excluded.
Exclusion criteria patient data:
Patients <75 years of age or not admitted under the enrolled clinical teams.
Exclusion criteria, semi-structured interviews:
Clinical teams not enrolled in the intervention.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will not be concealed. This is a stepped-wedge study design and all participants receive the intervention at some stage.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratification pre-enrolment:
To inform a stratified ordering of clinical teams for purposive sampling that will maximise a sample of patients aged 75 years or over, we will firstly identify the number of patient admissions aged 75 years or over for 1 to 7 February, 1 to7 May, 1 to7 August, and 1 to 7 November in the previous 12 month period per eligible clinical team per hospital. Based on this information, we will develop an ordered sampling list that considers the average number of admissions per clinical team and prioritises medical specialties. A purposive sampling approach will be followed until the study team has recruited seven clinical teams at each participating hospital during the four-week recruitment phase.
The three participating hospitals will be randomly allocated to intervention timing through the allocation of hospital identifiers from 1 to 3 prior to commencement of the trial. These identifiers will dictate the allocation to the stepped-wedge study design. A study statistician will be responsible for computer generation of this study timing randomisation and the intra-hospital clinical team identifiers once all ethical and governance approvals are in place and all teams are enrolled at each of the three participating hospitals

Intervention assignment
Other
Other design features
Given the nature of the intervention, and the fact that each hospital receives the intervention, it is not possible to blind the clinical teams to the intervention. Concealment of allocation will occur in relation to the cross-over timing to the intervention phases. During the site preparation and clinical team recruitment phase the date the intervention exposure phase is commencing will be concealed from the hospital teams (including enrolled clinical teams, employed auditors, advisory group and site study team members). the project team will notify the hospital's advisory group, auditor and clinical team participants of their intervention establishment and intervention exposure phase activities. from this time point, the particular hospital's clinical teams will be aware of their allocation in the study.

Efficacy
Statistical methods / analysis
Sample size:
The sample size calculations were performed to ensure the study has sufficient statistical power for the analysis of the first outcome measure, the proportion of high-risk CriSTAL or SPICT-positive patients who had one or more ICU admissions (primary outcome). Simulation-based sample size calculations were used to determine adequate sample to power the analyses. Information used in the patient hospital episode simulation procedure was obtained from a previous study estimating the incidence and impact of non-beneficial treatment in three tertiary public hospitals in the same state. In particular, we calculated the proportion of patients aged 75 years or older who had one or more ICU admissions during their hospitalisation, stratified by their retrospectively identified non-beneficial treatment status.
Statistical analyses:
Outcome 1 will be analysed using a Binomial regression with the patient ICU admission as the binary response variable. The key variable is the timing of the switch from baseline to intervention phase, so the main result of this analysis will be the intervention effect on the proportion of patients with at least one ICU admission.
Outcomes 2 to 7 will use competing-risk, proportional hazards survival models.
Outcomes 8 and 9 will use statistical distributions to describe variability in all cost parameters.
Process evaluation outcomes will be subject to thematic analysis.
