Abstract
OBJECTIVE
The Snapshot of Suspected ACS Assessment (SSAASY) study aims to describe the assessment processes for patients with suspected acute coronary syndrome (ACS) in Australian EDs, and to compare these processes with the National Heart Foundation of Australia and Cardiac Society of Australia and New Zealand (NHFA/CSANZ) guidelines.
METHODS
Between March and May 2021, a cross-sectional survey of Australian EDs was undertaken to investigate the assessment strategies used within the ED. All public and private hospitals identified as having dedicated EDs were invited to participate. Respondents provided data on hospital, ED and cardiac service characteristics. They also provided data on the risk stratification process recommended within their department (risk scores, troponin testing, objective testing for coronary artery disease). Awareness of the NHFA/CSANZ guidelines was assessed.
RESULTS
Responses were received from 109/162 departments (67%). Most sites (n = 100, 92%) reported using dedicated protocols developed by ED clinicians that included risk stratification scores. Highly sensitive troponin assays were used at 103 (94%) sites. Serial troponin testing was performed over 2 h for low-risk patients in 53 (49%) sites and 2-3 h for intermediate and high-risk patients in 74 (68%) sites. Further investigations included exercise stress tests (48%) and stress echocardiography (38%), with 45% of sites ordering outpatient investigations.
CONCLUSIONS
The SSAASY study reported the strategies used to assess suspected ACS. In line with current NHFA/CSANZ guidelines, highly sensitive troponin assays are widely utilised. However, serial sampling intervals were longer than guideline recommendations, suggesting a translational gap between guidelines and clinical practice.
