How to Read an EMS Run Report: Response, Scene and Transport Intervals From the ePCR (Free Tool)

By John Mahoney · January 5, 2027 · 7 min read

Every prehospital case starts with the same arithmetic: how long from the call to the crew, how long on scene, how long to the hospital, and what was done inside each of those windows. The ambulance patient care report has the raw times, but it does not compute the intervals, the times were typed in by the crew, and the narrative was written after the fact. This post shows how to pull a defensible prehospital timeline out of an ePCR in under an hour, what to compare it against, and which records turn a question into an answer.

What an ePCR actually contains

Electronic patient care reports vary by vendor, but almost all of them follow the national EMS data standard, so the same pieces are there under different headings:

• The time grid. Call received or PSAP time, unit notified, en route, arrived on scene, arrived at patient, departed scene, arrived at destination, transfer of care, back in service. These are the data elements the NASEMSO/NEMSIS time-interval definitions use to compute response, scene and transport intervals, and they are the vocabulary your expert will use.
• Dispatch information. The complaint as dispatched, the priority, and the unit's level (BLS or ALS).
• Assessment and vitals. Each set of vital signs with a time, the primary impression, and the exam.
• Interventions and medications. What was done, by whom, at what time, and the documented response.
• Destination and transfer. Where the patient was taken, why, and who received the handoff.
• The narrative. The crew's prose account, written at or after the end of the call.

What to look for

1. Compute the intervals yourself

Response interval, scene interval and transport interval, from the documented times. Then note which times are missing. An "arrived at patient" time that is blank, or identical to "arrived on scene" on a call to the ninth floor of an apartment building, is a fact about the documentation before it is a fact about the care.

2. Check the ePCR against the CAD log

The computer-aided dispatch log is stamped by the system; the ePCR is typed by people. Where they disagree, the CAD log usually controls, and the ePCR audit trail shows the edits. Do not build a chronology on ePCR times alone.

3. Read the interventions inside the scene interval

A 28-minute scene time with an IV, a 12-lead, two medications and a splint documented inside it is a different record from a 28-minute scene time with one set of vitals. Neither is a conclusion; both are deposition questions.

4. Vitals frequency

One set of vital signs on a 25-minute transport means the chart shows one reassessment. The cardiac monitor records every reading whether or not the crew charted it, so the monitor download is the record that settles what the patient's pressure and rhythm actually did.

5. Interventions without a documented response

"Nitroglycerin 0.4 mg SL" with no repeat blood pressure, "albuterol" with no repeat lung sounds, "epinephrine" with no rhythm check. Each is a records request (monitor download, drug log) first and a question for the crew second.

6. The destination decision

Trauma, stroke, STEMI and cardiac-arrest destination rules are set by the regional protocol in force on the date. The run report tells you where the patient went and, sometimes, why. The dated protocol tells you whether that was the designated choice. Get both before an expert is asked.

A worked example (hypothetical)

The facts below are invented for illustration. No real patient, agency or case is described.

A 54-year-old woman calls 911 for chest pressure and shortness of breath. She arrives at a community hospital, is diagnosed with an anterior STEMI, and is transferred to a catheterization lab ninety minutes later. The family asks whether the ambulance should have gone to the cardiac center eleven miles further.

Pasted into the decoder, the time grid reads: call received 19:02, unit notified 19:03, en route 19:05, on scene 19:14, at patient (blank), depart scene 19:41, at destination 19:52, transfer of care 20:06. Computed: response 11 minutes, scene 27 minutes, transport 11 minutes, and a 14-minute gap between arrival and documented handoff. The vitals table shows two sets, at 19:20 and 19:38. Interventions: aspirin 324 mg at 19:22, a 12-lead ECG at 19:24 with the interpretation field reading "***ACUTE MI SUSPECTED***", nitroglycerin at 19:26 with no repeat blood pressure documented, IV access at 19:33. Destination: "closest appropriate facility per patient request." The flags list notes the blank at-patient time, the 12-lead interpretation followed by a 17-minute remaining scene interval, the single post-nitroglycerin vital set, and the absence of any documented contact with medical command or a STEMI pre-notification.

For plaintiff counsel, the next requests write themselves: the CAD log, the monitor download with the 12-lead and its transmission log, the radio and medical-command audio, and the regional STEMI destination protocol dated that month. For defense counsel, the same list is the material that may show the patient did refuse the farther hospital, that the 12-lead was transmitted, and that the protocol allowed the closest facility. The decoder did not decide any of that. It made sure the right questions were asked before the expert was retained.

What to request next

• The CAD log with every system time stamp and unit status change.
• The 911 call audio, radio traffic and any recorded contact with medical command or online medical control.
• The ePCR audit trail: creation, edit and lock history, with user IDs and time stamps.
• The cardiac monitor or defibrillator download: event log, every vital-sign reading, 12-leads and their transmission records, CPR data, shocks, pacing.
• The agency's protocols and destination guidelines in force on the date, with the medical director's signature and effective date.
• Crew certifications and licensure, unit staffing level (BLS or ALS) and the agency's licensure.
• The receiving hospital's triage note, ED arrival time and EMS handoff record.
• Any refusal or against-medical-advice form and the capacity assessment, if the patient declined care or a destination.

What the tool does not do

The decoder organizes what the pasted report says and does the interval arithmetic from the documented times. It does not judge whether an interval was too long, whether a destination was correct, or whether an intervention was indicated; those depend on the protocol in force and on an expert's reading. Blank fields are reported as blank, not as failures. Every quote it produces is drawn from your text; verify each against the page before it goes into a chronology, a demand or an expert packet.

Frequently asked questions

Why does the EMS run report disagree with the dispatch log?

Electronic patient care report (ePCR) times are often entered or corrected by the crew after the call, sometimes hours later. The computer-aided dispatch (CAD) log is time-stamped by the dispatch system as each status change is radioed or keyed in. Where the two disagree, the CAD log is usually the better evidence of when the unit actually moved, and the ePCR audit trail shows who changed what and when.

What does the free EMS Run Report Decoder actually do?

You paste the text of an EMS or ambulance patient care report. It returns the prehospital time grid (call received, dispatched, en route, on scene, at patient, depart scene, at destination, transfer of care) with the response, scene and transport intervals computed from the documented times, a vitals table, each intervention with any documented response, the destination decision, flags grounded in the text, and the records to request. It does not decide whether any interval was too long.

What should I request beyond the run report?

The CAD log with every system time stamp, the 911 audio and radio traffic including any medical command recording, the ePCR audit trail, the cardiac monitor or defibrillator download, the agency's protocols and destination guidelines in force on the date, crew certifications and unit staffing level, and the receiving hospital's triage note and handoff record.
