Summary

The Manchester Triage System (MTS) effectively identifies critically ill patients upon arrival in emergency departments. However, some deterioration post-arrival was missed, often due to coder training rather than the system itself.

Area of Science:

  • Emergency Medicine
  • Healthcare Systems Analysis
  • Patient Triage

Background:

  • The Manchester Triage System (MTS) is a widely adopted emergency department triage tool in the UK.
  • Clinical outcome validation studies for the MTS were previously lacking.
  • Triage system safety involves balancing critical illness detection with resource management.

Purpose of the Study:

  • To evaluate the reliability of the MTS in identifying patients requiring critical care admission.
  • To assess the accuracy of MTS coding in detecting critically ill patients.

Main Methods:

  • Retrospective analysis of emergency admissions to critical care.
  • Comparison of actual patient outcomes with initial MTS triage codes assigned by nurses.
  • Expert retrospective coding and case analysis to identify coding errors.

Main Results:

  • 67% of critical care admissions received a high-urgency MTS category (1 or 2).
  • 18 lower-priority cases resulted from incorrect nurse coding.
  • The MTS accurately identified critically ill patients on arrival, but missed some deterioration post-arrival.

Conclusions:

  • The MTS demonstrates sensitivity in detecting patients needing critical care who are ill upon arrival.
  • The system's failures were primarily attributed to coder training issues, not inherent flaws.
  • Auditing critically ill patients is effective for assessing MTS sensitivity.
