Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The SC4RC model of care intervention comprises of three components to be offered to all participating GPs:
(1) Paediatrician primary and secondary co-consulting sessions with GP practices.
Paediatricians will be allocated to GP practices and made available for in-person or telehealth co-consultations for half a day a week over a 11-month period. Primary consultations includes GP-paediatrician co-consultation sessions with the paediatric patient in-person or via telehealth. Secondary consultation includes informal GP-paediatrician consultations in-person or telehealth on patient advice and/or clinical queries.
The study paediatricians will preferentially see children referred by participating GPs. Paediatricians will record the nature and outcome of primary and secondary consultations provided (e.g., patient age, sex, presenting problem, patient outcome) through a secure online databased (REDCap software).

(2) Dedicated weekday Paediatrician phone and email support for participating GPs.
Participating GPs will have access to dedicated phone and email support from study Paediatricians throughout the intervention period on all weekdays. GPs will be able to seek same day advice on children they would normally refer to OP clinics or the ED. Paediatricians will record the number and nature of emails and phone calls received through REDCap.

(3) Case based discussion Community of Practice
Continuing professional development will be delivered through the Project ECHOTM (Extension for Community Healthcare Outcomes) online telementoring programme. Facilitated by UoM and WVPHN (accredited ECHO replication sites), this programme aims to create communities of practice by bringing together healthcare providers and subject matter experts using videoconference technology, brief presentations and case-based learning. The community of practice session will be held monthly with all participating GPs where they will engage in knowledge network by sharing clinical challenges and learnings from experts and peers.
The project team will attend each session and record attendance as well as the nature of cases discussed. Adherence to the components of the model will be measured through weekly audit of data entries by the project team. Any missing recorded consultations and clinical notes will be followed up with each paediatrician

Comparator / control treatment
A stepped-wedge cluster randomised control trial (cRCT) will be used to evaluate the SC4RC model of care compared with standard GP care. Each GP practice will provide one month of standard GP care (control data via referral and medical record data) before being exposed to the SC4RC intervention. The first GP practices (1 in each state) to commence the intervention will complete one month of standard GP care before introducing the model, with one practice per state to commence the model per month after that.

Outcomes
Primary outcome [1] 333658 0
Assess the impact of SC4RC on GP quality of care for 15 common childhood conditions (e.g asthma/wheeze, bronchiolitis, constipation/abdominal pain, upper respiratory infections, infant crying and reflux); measured as change in proportion of unnecessary tests or prescriptions during the intervention period compared with pre-intervention GP care. This will be measured via GRHANITE extraction of GP medical records as part of paediatric GP consultations at the beginning of the control data period and throughout the intervention period
Timepoint [1] 333658 0
Collected as part of paediatric GP consults at the beginning of the control data period and throughout the intervention period.
Primary outcome [2] 333659 0
To assess the impact of SC4RC on the proportion of children and young people’s completed appointments that result in a referral to OP clinics or EDs at their appointment during the intervention period compared with the control period. This will be assessed via extraction of GP referral data (including no referral made) from GP electronic medical records at the conclusion of each pediatric appointment.
Timepoint [2] 333659 0
Collected as part of paediatric GP consults at the beginning of the control data period and throughout the intervention period.

Secondary outcome [3] 417874 0
Assess the cost-effectiveness and cost-benefit of the SC4RC model of care compared with standard GP care by undertaking a health economic evaluation. The economic evaluation will use study protocols clinician logs and project budgets to construct the cost of conducting the SC4RC model of care relative to usual care. The incremental cost associated with SC4RC outcomes (Quality of care; ED/outpatient attendances) will be sourced from the trial database, GHRANITE software and trial hospitals (cost of ED and hospital visits). Parental time, productivity, travel and child school attendance will be self-reported by parents through the parent survey.

Data will be collected throughout the model of care.
Secondary outcome [4] 417876 0
Assess the implementation of the SC4RC program including fidelity from the perspectives of practitioners and families and factors that help or hinder this implementation. This will be a composite outcome measured using the Consolidated Framework for implementation Research measure (CFIR) and the Normalisation Process Theory measure.
Timepoint [4] 417876 0
1. Interim qualitative data will be collected via focus groups with GP practice, 6 months into the model of care (iterative data collection process). Focus group data collection will include recorded GP self-reported experience data 2. Qualitative interviews will also be collected upon completion of the model of care in each GP Practice; paediatrician data will be collected as part of the co-consultations, case study discussions and phone/email support throughout the model of care). 3. Online survey data will be collected upon completion of the model of care for each GP practice using the Normalisation Process Theory measure 4. Sustainability online survey data will be collected 4 months post-completion of the model of care in each GP Practice using study-designed questions to measure use of intervention recourses, changes in clinical practice, and long-term confidence in paediatric care.
Secondary outcome [5] 417877 0

Other design features
The stepped-wedge structure of this trial will see that all GP Practices receive the intervention for the same period of time (11 months), however this will occur across a 22-month period (with two Practices taking on the intervention each month).
Participating GP practices within each state will be randomly ordered in terms of when they switch from standard GP care to the SC4RC model by the independent statistician. Practices will switch to the SC4RC model on a month-by-month basis over an 12-month period (one practice switching in each state per month)

Efficacy
Statistical methods / analysis
Analyses will follow the ‘intention to treat’ principle. The primary outcome of quality care indicators assessed will be analysed using mixed effects logistic regression models with a random effect to account for the clustering of the indicators within the same GP practice. The effects of intervention status (intervention period versus control period) and indicator for calendar time (having association with both the intervention status and the outcome) will be analysed as fixed effects.
Secondary outcomes collected at the consult level (e.g. referral to paediatric services, GP confidence, and family trust) will also be analysed using mixed effects linear and logistic regression models with fixed effects for intervention status and calendar time, and a random effect for the clustering of the consults within the GP practice. We will explore the potential clustering at the consult, patient and GP level, however as aforementioned from our previous work, variation is predominantly accounted for at the practice level.
These regression analyses will be conducted for all the 15 conditions simultaneously and for each of the 15 conditions separately. Where relevant, we will control for factors at patient (eg, sex, age) and GP practice level e.g size of practice that may have a plausible confounding effect on the relationship between the intervention and the outcomes. We will also examine if the intervention effect changes with the GP practice’s length of exposure to the intervention by including in the regression analyses the interaction term between intervention status and the length of exposure to the intervention. Participants with missing values will be included in the regression analyses, as data missing is assumed to be at random under these models. The statistician responsible for the data analysis will be blinded to the data collection to reduce the risk of bias.
Economic Evaluation
The economic evaluation will be assessed using a standard economic evaluation framework to determine the costs of conducting SC4RC (paediatrician time and supervision, GP training, practice administrative support, co-consults, and case-study discussions) relative to usual care. This information will be combined with the incremental cost associated with SC4RC outcomes (ED presentations, outpatient attendances). The costs of implementing the model will be scaled to national level along with a budget impact analysis from the perspective of potential payers (Medicare, PHNs, Hospitals, Families) to guide translation of findings and sustainable implementation.

Implementation Evaluation
A mixed method implementation evaluation, using the Consolidated Framework for Implementation Research (CFIR; www.cfirguide.org), will be undertaken to understand how and why our intervention was effective or ineffective in producing systems change. The study team will thematically analyse transcripts to identify, interpret and report on the repeated patterns of meaning within the data, influenced by the CFIR constructs. All interview data will be digitally audio recorded, transcribed verbatim and transcripts will be analyzed thematically using qualitative software (Nvivo 10) to sort emerging themes.

Questionnaire data and open-ended questions from surveys will be exported into STATA for analysis.. Describing the number and proportion of children seen in GP-Paediatrician co-consultations, reasons for co-consultations, number of phone and emails to the paediatrician support, number and topic of case study discussions as part of the SC4RC program over the study period, will be assessed using summary measures of the variables of interest during the intervention period only.

Sustainability
Sustainability of the intervention effects will be assessed using mixed effects logistic regression of the referral data fitted at the child level applied to data collected during the sustainability, control and intervention periods.
