Assessment of risk is part of the chest pain assessment process within Emergency Departments. In 2016, the National Heart Foundation and Cardiac Society released guidelines advising that selected patients requiring rule out of Acute Coronary Syndrome in the Emergency Department can have a shorter assessment process. This project aimed to provide Emergency Departments across Victoria with guidance about how to combine clinical risk stratification, ECG and troponin testing; along with structure on how to guide patient management in a clear clinical pathway documentation process.

Background: The Emergency Care Clinical Network actively engages with emergency clinicians in creating and building sustainable improvements and innovation in the delivery of emergency care in Victoria. A key focus is to enhance the use of evidence-based care to reduce variation in clinical practise and improve patient care. Within this project: patients were considered eligible for the rapid rule out pathway if they had no high risk features, a modified TIMI score of 0 or 1, depending on the troponin assay used and a normal or unchanged ECG. Implementation of rapid rule out Acute Coronary Syndrome pathway for eligible patients would be in parallel with ‘standard’ practice for other patients.

Results: In 2016, a similar project was conducted; the median change in length of stay for the rapid rule out group over nine months was 96 minutes. The median change in length of stay was 58 minutes. This year the project aims to build on those, with results due November 2017.

Findings: The rapid rule out pathway reduced the average length of stay for patients in the Emergency Department using evidence based practice to guide clinicians. Extended benefits included clear discharge planning and patient education which improved patient centred care.

Summary: Implementation of the rapid rule out pathway in the Emergency Department enhances patient care by reducing variation in clinical practice based on evidence resulting in reduced length of stay and improved patient centred care.
