Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Interventional
Description of intervention(s) / exposure
Clinical pathways in this study are standardized algorithms for the treatment of acute coronary syndromes that aim to optimize and streamline patient care. They are established according to American Heart Association (AHA) and American College of Cardiology (ACC) guidelines to promote the use of evidence-based treatments for high risk patients and ultimately, improve clinical outcomes. The clinical pathways are designed to accompany the patient’s medical record and available in printed copy. In this study after baseline data collection, the printed clinical pathways as a reminder of guideline adherence will be added in front of patient’s medical record in relevant departments in the participating hospitals. The clinical pathways will be used for at least 24 month in participating hospitals. Its impact will be evaluated periodically (every 6 months) by comparing a series of key performance indicators, e.g. average door-to needle time and average door-to-balloon time for patients with ST elevated myocardial infarction.
Intervention code [1] 236649 0
Behaviour
Comparator / control treatment
1. Randomized comparison: hospitals will be selected to implement the clinical pathways “early” and to implement “12 month later”. Approximately one-half of the 75 participating hospitals will be allocated (at random, stratified by hospital size and level) to commence the study in the first year of the full program (Group A), while the remaining one-half (Group B) will commence during the second year. This staggered commencement will be necessary from a logistic viewpoint, but will also provide the opportunity to make a randomized evaluation of the intervention program on the key performance indicators (12 month data for Group A vs. baseline data for Group B).
2. Non-randomized comparison: a “before-after” comparison in key performance indicators among all 75 hospitals will be conducted from up to 3750 patients (50 patients from each of the 75 hospitals) at each 6-month interval with baseline and the previous 6-month time periods. After 24 months, summary data will be available for over 15000 patients to examine overall trends in key performance indicators.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The randomisation was performed at hospital level. Allocation of hospitals to early or later commencing group was concealed by central randomisation by computer. Allocation is not concealed at individual patient level.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
