Evaluation of the Manchester triage system for patients with acute coronary syndrome
Key result
The Manchester Triage System classified 92.9% of acute coronary syndrome patients as level 2 or 3, with no significant difference in mean triage levels between STEMI, N-STEMI, and unstable angina.
Why the study?
Early diagnosis of acute coronary syndrome is crucial for treatment and prognosis, prompting an evaluation of the Manchester triage system for patients with ACS.
How are patients with acute coronary syndrome classified by the Manchester triage system in the emergency department?
Population
282 patients diagnosed with ACS triaged in the emergency department
Comparison
MTS levels across ACS types and patient subgroups
Design
Retrospective analysis

Implication
MTS assigned most ACS patients to levels 2–3 without subtype differentiation; leaves open whether immediate ECG protocols independent of triage improve early STEMI detection.

How are patients with acute coronary syndrome classified by the Manchester triage system in the emergency department?
P
Population
282 patients with acute coronary syndrome (STEMI, N-STEMI, and unstable angina) presenting to the emergency department of a single center in Austria.
E
Exposure
Manchester triage system (MTS)
O
Outcome
MTS level assignment
The Manchester triage system does not reliably differentiate between STEMI, N-STEMI, and UAP, highlighting the need for immediate ECG in all suspected ACS patients regardless of triage level.
Limitations
- Single center experience
- Retrospective design can only be considered as hypothesis generating
- Limited number of patients

Kiblboeck et al. (2020) conducted an observational in Acute coronary syndrome (n=282). Manchester Triage System (MTS) was evaluated on Distribution of different MTS levels in patients with ACS. The Manchester Triage System classified 92.9% of acute coronary syndrome patients as level 2 or 3, with no significant difference in mean triage levels between STEMI, N-STEMI, and unstable angina.
