The history of triage started from the French battle field. In- hospital ED triage started in early 1960's from Baltimore. It is now an essential component of modern ED. Triage is not only to sort out patients as per their criticality, but it also serves the purpose of streamlining the patients so that the patient receives right treatment at the right time in the appropriate area. It helps to manage the ED overcrowding by better flow of patients. AKUH-ER experience of triage dates back to the year 2000, when triage was conducted by physicians and there used to be a manual documentation of patient's particulars such as complaints, vitals and BP. With the expansion of AKU-ED in 2008 responsibility of triage shifted to nursing services. Triage policy was drafted and implemented and for guidance and uniformity of care, triage protocols were developed. Another important development is replacement of register with triage data entry software. This help us to monitor some indicators like number of patients triaged, the time between triaging and actual bed assignment, triage categorization, length of stay, dispositions and return visits. The available information now helps us to make decisions based on evidence and also paves the way for future direction.
