Before the ED: What the EMS Run Report Establishes in a Medical Record Review

"Pt ambulatory at scene, states she was rear-ended at low speed, denies LOC. Ambulatory to unit. C/o neck stiffness en route."

Four lines in a run report narrative. In many files, that paragraph is the earliest written account of the incident, and it usually gets read once and set aside in favor of the emergency department record that follows it.

That is a mistake a medical record review should not make. The prehospital record carries evidence no later document can reproduce, and it carries a specific trap that catches reviewers on both sides.

Three Documents, One Hour

What people call "the ambulance record" is usually three separate documents written by three authors inside about an hour.

• The dispatch or CAD record. Generated by the communications system. It holds the call time, the address, the complaint as the caller described it, and the unit times.
• The EMS patient care report. Written by the responding crew, covering assessment, treatment and transport. The data elements in it follow a national standard: NEMSIS, a program of NHTSA's Office of EMS, "develops and maintains a national standard for how patient care information resulting from prehospital EMS activations is documented."
• The ED triage note. Written by a nurse minutes after arrival, often repeating what the crew said in the handoff rather than recording anything new.

Those last two are frequently mistaken for independent accounts. A triage note reading "per EMS, restrained driver, no LOC" is not corroboration. It is the same statement, moved one step down the chain, and a review that treats it as a second source inflates what the file establishes.

Four Things Only This Record Carries

Each of the four has a limit that belongs in the review next to it.

1. Times generated by a system, not a person

Call received, dispatched, en route, on scene, left scene, arrived at hospital. These come from the communications system rather than from recollection, which makes them useful for anchoring everything else in the timeline.

What they do not establish: the time of the incident itself. The call time is when someone dialed, which can be minutes or much longer after the event. Clock synchronization between agencies and hospitals also varies, so small discrepancies between the EMS and ED clocks are common and rarely mean anything.

2. Mechanism recorded at the scene

Direction of impact, restraint use, airbag deployment, fall height, position on arrival, vehicle damage, whether the patient was ambulatory. These details are rarely repeated with the same specificity later, and by the time of deposition they are memory.

What they do not establish: that the mechanism happened as described. See the next section, which is where most of the trouble in these records sits.

3. Vitals and mental status before treatment

Initial blood pressure, pulse, respiratory rate, oxygen saturation, Glasgow Coma Scale and pupil findings, recorded before analgesia, immobilization or hospital care.

What they do not establish: a later condition. A normal prehospital neurological exam is a finding about that examiner, at that minute, under scene conditions. It is dated evidence, not a ruling.

4. Scene observations and transport decisions

What the crew saw rather than what they were told: intrusion into the passenger compartment, a windshield starred from the inside, the patient found seated on a curb, a walker left in the roadway. Transport decisions belong here too. Field triage in the United States follows the National Guideline for the Field Triage of Injured Patients, published by the American College of Surgeons with NHTSA and HRSA support, which helps crews decide which patients go to which level of trauma center.

What they do not establish: severity. A patient transported to a trauma center was triaged under a protocol, not diagnosed, and a patient taken to the nearest community hospital was not thereby found to be uninjured. Protocols and destination rules also vary by state, region and agency, so the review notes the decision and leaves its meaning to the reader.

Who Said the Mechanism?

The single most quoted line in a prehospital record is usually the least verified. "Rear-ended at approximately 35 mph." "Fell approximately 10 feet." "Struck on the left side by a vehicle that ran the light."

Almost none of that is the medic's observation. It came from the patient, a family member, a bystander or a police officer at the scene, and it was written down in the same font as the blood pressure. The record is accurate about what was said. It is not evidence of what happened.

A review should attribute every mechanism statement to its speaker when the record identifies one, and say so plainly when it does not. "Patient-reported mechanism, EMS narrative, page 2" and "crew-observed vehicle intrusion, EMS narrative, page 2" are two different pieces of evidence sitting in the same paragraph. That is the same discipline behind not treating every medical note the same.

Speed and distance estimates deserve an extra flag. They are usually approximations offered under stress, and they tend to harden into facts as they are repeated through the ED note, the specialist consult and the demand letter. When a number first appears in a run report as an estimate, the review should show where it entered the record, because that is the question the other side will ask.

The prehospital entries are also the first links in the sequence a case is built on. Getting the source right at this end of the medical evidence chain decides how much weight everything downstream can carry.

Refusals, Non-Transports and the Record That Almost Does Not Exist

Some of the most contested prehospital documents are the ones created when nobody went to the hospital. A refusal form signed at the scene typically documents that assessment was offered, that risks were explained and that the patient declined transport.

What it does not document is the absence of injury. Patients decline transport for reasons that have nothing to do with how hurt they are: no insurance, no childcare, a car to deal with, or symptoms that had not started yet. A review should record the refusal, the vitals and findings taken before it, any documented advice to seek care, and nothing more.

Then there is the file with no prehospital record at all. Three explanations look identical on a page: EMS was never called, the records were never requested, or the agency's retention period passed before anyone asked. Retention rules differ by state and agency, and by the time a claim matures, older records may be gone. The review should state which explanation the file supports and flag the rest as open, rather than describing a documentation gap as a treatment gap. Small entries like this are where small details create big case questions.

What Each Reader Takes From It

• Plaintiff firms use the crew's own observations and the pretreatment vitals, which are hard to characterize as litigation-driven because they predate the claim.
• Defense counsel and carriers read the mechanism line against the vehicle evidence and the later history, and they read "ambulatory at scene" closely.
• Workers' compensation teams compare the dispatch address and call time against the employer's first report and the shift record.
• IME and QME providers often receive the hospital record without the run sheet, which removes the only pretreatment exam in the file.

Where the Review Stops

Three layers, kept apart: what the record documents (a GCS of 15 at 14:22, a patient-reported rear-end impact, transport to a community hospital); what the reviewer can identify (the mechanism came from the patient, the triage note repeats the crew rather than adding a source, the speed estimate first appears here); and what a qualified professional decides (whether the forces described could produce the injury claimed, and what any of it means legally).

Start Where the Record Starts

The first hour of documentation is short, cheap to obtain and routinely under-read. It holds the only timestamps nobody had to remember, the only exam performed before treatment, and the first written version of a story that will be retold a dozen times.

Pull it. Date it. Name who said what. Then the rest of the file can be measured against something.
