Description of intervention(s) / exposure
Evaluating the rate of attendance for follow up exercise stress testing in patients who were given pre-organised appointment times.
Evaluating the representation rate with cardiac related chest pain, adverse cardiac events, coronary intervention procedures and mortality over 30 days following their discharge.

Comparator / control treatment
Historical control group: this group of patients are patients who have been discharged with the same inclusion criteria as the experimental group but were not given pre-organised appointment times. Rather they were asked to make their own appointment or contact their general practitioner for a referral for exercise stress testing. The control group have been selected from patients meeting the inclusion criteria between January 2010 to June 2010 from the same hospital (Armadale Health Services)

Outcomes
Primary outcome [1] 266671 0
To determine whether providing patients with pre-organised appointment times increases their compliance to return for exercise stress testing.
Timepoint [1] 266671 0
Follow up will occur at day 30 post discharge from the emergency department in order to evaluate their compliance with attending exercise stress testing
Secondary outcome [1] 276164 0
To determine the 30 day mortality rate of patients discharged with a diagnosis of intermediate risk ACS.
Timepoint [1] 276164 0
Day 30 post discharge from the emergency department
Secondary outcome [2] 276165 0
To determine the likelihood of major adverse cardiac events in patient who returned for EST compared to those who did not.
Major adverse cardiac events include ST-elevation myocardial infarcts, angioplasty/stent, Coronary Artery Bypass Grafting (CABG), stable and unstable angina.
This outcome will be assessed by collecting data from health department databases and software and performing telephone interviews with patients.
Timepoint [2] 276165 0
Day 30 post discharge from the emergency department
Secondary outcome [3] 276166 0
To determine what barriers prevent patients from attending follow up EST.
This outcome will be assessed with telephone interviews and questionnaire.
Timepoint [3] 276166 0
Day 30 post discharge from the emergency department
Secondary outcome [4] 276167 0
To determine the patients' perceived risk of future cardiac events compared to their actual risk determined by the guidelines set out by the National Heart Foundation/Cardiac Society of Australia and New Zealand.
The patient will be asked to perform a questionnaire over the telephone that will address their perceived risk on an alphabetical scale. (ie A) 1-2%, B) 3-4% etc)
Timepoint [4] 276167 0
Day 30 post discharge from the emergency department

Summary
Brief summary
Patients with chest pain presenting to the emergency department are stratified according to likelihood that the pain is due to a heart attack. “Intermediate risk” chest pain may be cardiac in origin but is not due to a heart attack, and requires further follow up. According to current Australian guidelines, these patients should be referred for an exercise stress test within 72 hrs to further clarify their risk.

Currently only 30% of patients with intermediate risk chest pain present for their stress test within 72 hours even if stress testing services are readily available on site. We are investigating whether a fixed appointment time given to the patient before they leave the ED results in an improved follow up rate and improved 1 month outcome.
