Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All Rural Emergency Departments within a Local Health District are randomised to either usual care or a mandated transmission of ECG and troponin from spoke (Rural) hospitals to a central hub service. Protocol directed advice from the NSW Health Chest Pain Pathway will be given to the randomised Rural Hospital clinicians by telephone, and will channel patients into the existing ACS management structures: The State Cardiac Reperfusion Strategy (SCRS) for STEMI patients, and the NSW Chest Pain Pathway for non-STEMI patients.
Phone calls to interventional sites will be made within the first 30 minutes of the patients initial arrival to Hospital and as required thereafter during the patients initial presentation to Hospital until the patient is discharged from the Emergency Department or transferred to a Referral centre. Thirty-day and 12-month readmission rates (and reasons) will be identified through the patient information management system, and Centre for Health Record Linkage (CHeReL). Deaths will be identified through the National Death Index. Advice provided will be based on the ECG, Patients troponin, and presentation once established, ensuring consistency with chest pain pathway. Advice will include one of the following dependent on this clinical information; Return to routine care, Conference call to a Cardiologist for advice and potential pt transfer, Advice for admission and transfer to referral Hospital. Clinical data and Advice provided is documented on the research database for analysis at the end of the trial. ECGs will be independently reported and compared with the MORACS service interpretation at the end of the trial.
Clinicians providing protocol directed advice and referral will comprise of Senior Cardiology Nursing staff, with extensive experience in ECG interpretation, and management of patients with suspected Acute Coronary Syndrome.

Outcomes
Primary outcome [1] 319434 0
Proportion of correctly identified STEMI (indicator 3b ACSQHC). ECGs will be adjudicated by a senior clinician. ECGs performed on all patients presenting with possible ACS will be analysed.
Timepoint [1] 319434 0
Analysis of the primary outcome will occur at 2 years following 15 months of patient recruitment.
Secondary outcome [1] 368181 0
In Hospital Mortality
Timepoint [1] 368181 0
Assessed at end of Hospitalisation
Secondary outcome [2] 368182 0
Time to coronary reperfusion from presentation in patients with myocardial infarction. This will be measured from presentation to Hospital to resolution of ST segment elevation in patients with STEMI that receive thrombolysis, or for those that undergo percutaneous intervention, from time of presentation to TIMI III flow (which ever occurs first). This will be assessed by presentation time stamp automatically generated from the patient administration system, the Electronic ECG database and the patients digital medical record.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealed - central randomisation by computer
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Hospitals are randomised to receive the intervention (MORACS) or control (usual care). Randomisation is undertaken independently by personnel from the HMRI statistical support unit via simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation).

Statistical methods / analysis
1) Power calculation: Based on local data, anticipated number of presentations to hospital with suspected ACS over a 12-month period are approximately 6,300, which includes HNELD and SWSLHD. Of these an estimated 50% will require admission and investigation for ACS. Around 15% of the total patient group will have non-STEMI and a further 5% have STEMI, i.e. ~315 STEMI per year across all centres. An estimated 36% of the patients with STEMI will be missed and we wish to detect an absolute reduction in missed STEMI of 16%, i.e. 36% down to 20%, which will require 280 participants (140 per arm), at 80% power and p=0.05. We also include a design effect of 1.24 (assuming cluster sizes of 13 and ICC=0.015) for a total of 338 patients across 26 clusters total. Therefore, it will take approximately 15 months to recruit. In the two-year timeframe, we will be able to analyse the rate of STEMI detection (primary endpoint) and will have a median 12-month follow-up for the secondary endpoints.
2) Evaluation of Results: Analysis of the primary outcome (the proportion of correctly identified STEMI) will be via logistic regression with adjustment for stratifying variables (size and staffing of hospital), and analysis of the secondary outcomes will be via linear and logistic regression.
3) Economic evaluation: Assuming an improvement in STEMI identification, three economic evaluations will be conducted. 1) From a health provider perspective, a cost-effectiveness analysis to report the resources required per unit improvement in the identification of STEMI. Costs will include the cost of the intervention as well as related costs such as hospital stay, treatments and readmissions. The measure of effect will be based on the primary outcome (identification of STEMI). 2) A cost-consequence analysis will report the cost of the intervention and its range of consequences such as the change in STEMI identification, reperfusion times, hospital admissions, readmissions and MIs. 3) A modelling exercise to estimate costs and potential downstream impacts from the intervention over a ten-year time frame, these will include avoided healthcare costs as a consequence of improved STEMI detection and treatment, as well as adherence to secondary prevention therapies. This will be informed by data linkage with MBS and PBS.

Summary
Brief summary
Aims: To improve identification and management of patients with ACS within rural hospitals in a Local Health District by implementing a hub and spoke ACS management system. MORACS clinicians will receive notification of patients presenting to intervention Hospitals with ACS symptoms, review ECG, troponin, clinical information and contact the site to provide advice on evidence based treatment.

Research Question: In patients admitted to a rural hospital with suspected Acute Coronary Syndrome (ACS), does a centralised management system improve identification of STEMI and subsequent clinical outcomes in all ACS patients?
