Three-Part Question:
In the [triage of Emergency Department patients], is [computer-assisted system better than standard nurse-led system] in [improving accuracy and hence safety]?
Clinical Scenario:
Your Head of Department is considering the use of a computerised triaging system. He wonders if this is a better method of triaging patients, compared to the traditional nurse-led triaging system.

Author Commentary:
To compare the accuracy of either triage system, the triage level generated by either system needs to be compared against a ‘gold standard’. In the study by Dong et al, the gold standard was the expert panel opinion of what the triage level should be. There are not many such studies available in the literature. This is likely due to the difficulty in designing and performing this type of comparative study.
Bottom Line:
In the triaging of emergency department patients, computerized triage maybe more accurate than nurse-led (memory) triage. The evidence for this conclusion is based only one study.
Level of Evidence:
Level 2: Studies considered were neither 1 or 3
