Door-to-triage time
How fast a patient who walks in is actually triaged and given an ESI level. Until triage happens, nobody knows whether the person at the door is a sprain or a STEMI — so this is the gate that protects every other timeliness target.
Capture & escalation pipeline
From the door to an ESI level, before billing — with the un-triaged-wait safety flag.
How it’s measured
- Numerator
- Patients triaged (ESI level assigned) within the target time of ED arrival.
- Denominator
- All patients arriving at the ED.
- Formula
- (Numerator ÷ Denominator) × 100, reported with the median door-to-triage time in minutes.
- Unit
- % within target (and median minutes)
Target
India: NABH expects every patient to be triaged on arrival; aim for triage within ~5 minutes of reaching the ED for walk-ins.
International: RCEM and ENA/ACEP: initial triage assessment within minutes of arrival, before any queue for registration.
Triage must come before billing/registration — a patient bleeding out should never wait at the cash counter.
Who does what
The clinical chain of responsibility at the bedside.
| Security / front desk | Directs every arrival straight to the triage point rather than the registration queue. |
|---|---|
| Triage nurse | Performs a rapid acuity assessment and assigns an ESI level the moment the patient arrives; records the triage time. |
| Registration clerk | Captures the door/arrival time; registration runs in parallel with or after triage, never before it. |
| ED in-charge | Ensures a trained triage nurse is always present and steps in during surges. |
What to capture & how it’s automated
Who captures it
Registration (arrival time) and the triage nurse (triage time + ESI level).
What is captured
Arrival timestamp and the time the ESI level was assigned.
Manual reality
Arrival on the casualty slip, triage time in the triage register. The gap is calculated by hand at audit, and is unreliable when registration and triage are done by the same overloaded person.
Automated in real life
A triage kiosk/tablet stamps arrival and ESI-level time automatically; the tracking board then shows anyone waiting un-triaged. This removes the temptation to back-fill triage times to look compliant.
Who in the hospital is involved
Beyond the bedside — the functions that make capture and improvement happen.
| Quality cell / QI nurse | Audits the median door-to-triage and flags any un-triaged waits. |
|---|---|
| ED nurse manager | Staffs a dedicated triage role and protects it from being pulled to other duties. |
| Medical records / HIM | Pulls arrival and triage timestamps for the monthly report. |
| IT | Maintains the triage tablet/kiosk and the tracking board. |
| Hospital administration | Enforces the 'triage before billing' policy at the front desk. |
Why it affects performance
Door-to-triage is the upstream gate for every other clock — door-to-ECG and time-to-provider cannot be met if triage is slow. A creeping triage time is the earliest sign the front door is overwhelmed.
Why it affects patient care
A time-critical patient who is not triaged is invisible to the system. Fast, accurate triage is what catches the silent STEMI, sepsis, or stroke before they deteriorate in the queue.
Capture pitfalls & gaming to watch for
- Letting registration/billing happen before triage, so sick patients wait at the counter.
- Recording triage time as registration time when one person does both.
- Counting only walk-ins and ignoring ambulance arrivals, which have their own clock.
- Treating triage as a clerical step rather than a clinical assessment.
What actually moves the number
- A dedicated, trained triage nurse on every shift, protected from other tasks.
- A clear 'triage first, register second' front-door policy.
- A triage tablet that stamps the ESI level and time automatically.
- A visible board showing anyone waiting to be triaged.
- Quick-look triage criteria so high-acuity patients are pulled instantly.
