Emergency Medical Services: Step-by-Step Guide on How to Write SOAP Notes

Written by SOAPNoteAI Editorial Team · Updated June 2026

The prehospital Patient Care Report (PCR) is one of the most legally significant documents in all of healthcare. It is often the only record of what a patient looked like at the moment of crisis: the scene, the mechanism, the first vital signs, and the interventions that may have saved a life. For EMTs and the broader EMS system, well-organized documentation is not paperwork after the fact but the clinical handoff and the legal defense for every decision made in the field.

This guide explains how to structure the body of an EMS PCR using the SOAP format, framed at the EMT and Basic Life Support (BLS) level. It covers scene size-up, the primary and secondary survey, serial vital signs, BLS interventions, patient refusals and against-medical-advice (AMA) documentation, and transfer of care. It is meant to complement, not duplicate, advanced (ALS/paramedic) documentation; where a skill or medication is outside the BLS scope, this guide notes that the paramedic record carries it. Whether you write narratives in pure SOAP, in the EMS-specific CHART format, or in your agency's ePCR template, the principles here will make your reports more complete, more defensible, and faster to produce.

What Makes EMS Documentation Unique

EMS documentation differs from clinic-based or inpatient charting in several fundamental ways:

1. The scene cannot be re-created: Mechanism of injury, hazards, patient position on arrival, and the environment are perishable observations that exist nowhere else. If the EMT does not capture them, they are lost.
2. It is the prehospital legal record: The PCR is discoverable in litigation, used by receiving facilities for ongoing care, and reported to state EMS offices and the NEMSIS national registry. A signature attests to its accuracy.
3. Time stamps are clinical data: Dispatch, en route, on scene, at patient, transport, and at destination times, plus the timing of each intervention, define the entire response and substantiate billing.
4. Scope of practice governs content: A BLS report documents BLS assessment and interventions; advanced airway, IV/IO access, cardiac monitoring, and most medications belong to the ALS provider. Documentation should never imply care outside the writer's certification.
5. Refusals and AMA are high-liability events: Documenting why a patient who declined care had capacity, was informed, and was offered alternatives is among the most important narratives an EMT will ever write.
6. Billing uses HCPCS A-codes, not CPT: Ground ambulance services are billed with HCPCS Level II A-codes (for example A0429 BLS emergency, A0425 mileage), and the narrative must substantiate medical necessity for transport.

Subjective Section (S)

In an EMS SOAP note, the Subjective section captures the reason EMS was called, what the patient and bystanders report, and the history obtained in the field. For prehospital care this section anchors on the dispatch information, the chief complaint in the patient's own words, and structured history tools such as SAMPLE and OPQRST.

Subjective Section (S) Components

1. Dispatch Information:

   • The nature of the call as dispatched and the priority/response mode.
   • Example: "Dispatched code 3 for a 64-year-old male with chest pain."

2. Chief Complaint:

   • The primary problem in the patient's own words when possible.
   • Example: "Patient states, I feel a heavy pressure in the center of my chest."

3. History of Present Illness (OPQRST):

   • Onset: What the patient was doing when symptoms began; sudden vs. gradual.
   • Provocation/Palliation: What makes it better or worse.
   • Quality: The patient's description (sharp, dull, pressure, burning, crushing).
   • Radiation/Region: Where it is and where it travels.
   • Severity: Patient-reported severity on a 0-10 scale.
   • Time: Duration and whether constant or intermittent.
   • Example: "Onset 45 minutes ago while mowing the lawn; described as pressure, 8/10, radiating to the left arm and jaw, not relieved by rest."

4. SAMPLE History:

   • Signs/Symptoms reported by the patient.
   • Allergies (medications, environmental, food).
   • Medications the patient currently takes, including OTC and recently taken doses.
   • Past pertinent medical history.
   • Last oral intake (time and what).
   • Events leading up to the present illness or injury.
   • Example: "Allergies: penicillin (rash). Meds: lisinopril, atorvastatin, aspirin 81mg daily. PMH: hypertension, prior MI 2 years ago. Last meal: lunch 3 hours ago. Events: symptom onset during yard work."

5. Bystander, Family, and First-Responder Information:

   • Pertinent history from those at scene, especially for altered, pediatric, or unresponsive patients.
   • Bystander CPR and AED use prior to EMS arrival, with estimated downtime.
   • Example: "Wife reports the patient complained of indigestion since this morning. No bystander interventions performed."

6. Pertinent Negatives:

   • Relevant symptoms the patient explicitly denies, which shape the field impression.
   • Example: "Denies shortness of breath, nausea, diaphoresis, and syncope."

Tips:

• Quote the patient when it strengthens the record, especially the chief complaint and refusal statements.
• Use SAMPLE and OPQRST as scaffolds so nothing is missed under time pressure.
• Distinguish what the patient reported from what you observed; observations belong in Objective.
• Document who provided history when the patient cannot (family, bystander, law enforcement).

Example of a Subjective Section for EMS

Objective Section (O)

The Objective section captures everything the EMS crew measured and observed: the scene, the primary and secondary survey, and serial vital signs. In the prehospital setting, objectivity and time stamps are paramount because these findings frequently cannot be reproduced once the patient leaves the field.

Objective Section (O) Components

1. Scene Size-Up:

   • Scene safety on arrival and any hazards (traffic, violence, environmental).
   • Number of patients and need for additional resources (ALS intercept, fire, extrication, law enforcement).
   • Mechanism of injury (MOI) for trauma or nature of illness (NOI) for medical.
   • BSI/PPE used.
   • Example: "Scene safe on arrival. Single patient. BSI observed. Two-vehicle MVC, moderate front-end damage, patient restrained, airbag deployed."

2. General Impression and Level of Consciousness:

   • The crew's first overall impression (sick vs. not sick).
   • AVPU (Alert, Verbal, Painful, Unresponsive) or Glasgow Coma Scale.
   • Orientation (person, place, time, event).
   • Example: "General impression: pale, diaphoretic adult in mild distress. AVPU: Alert. Oriented x4. GCS 15."

3. Primary Survey (XABCDE):

   • X - Catastrophic hemorrhage controlled if present.
   • A - Airway patent / maintained / compromised.
   • B - Breathing rate, effort, breath sounds, work of breathing.
   • C - Circulation: pulse rate and quality, skin color/temperature/condition, major bleeding, cap refill.
   • D - Disability: AVPU/GCS, pupils, gross motor/sensory.
   • E - Exposure/Environment: relevant findings once exposed, temperature considerations.
   • Example: "Airway patent. Breathing 22, slightly labored, lungs clear bilaterally. Radial pulses present, regular, strong. Skin pale, cool, diaphoretic. No external hemorrhage. Pupils equal and reactive."

4. Vital Signs (serial, with times):

   • Blood pressure, heart rate, respiratory rate, SpO2, and where appropriate temperature, blood glucose, and pain score.
   • Document a baseline set and reassess at intervals appropriate to acuity.
   • Example: "0912: BP 156/94, HR 92, RR 22, SpO2 95% room air, pain 8/10, BG 110 mg/dL. 0925: BP 148/90, HR 88, RR 18, SpO2 99% on 4 L/min NC, pain 4/10."

5. Secondary Survey / Focused Exam:

   • Head-to-toe inspection and palpation by region for trauma; focused exam for medical complaints.
   • Pertinent positives and negatives.
   • Neurovascular status distal to any injury (pulse, motor, sensory).
   • Example: "Chest: no deformity, equal expansion, non-tender. Abdomen soft, non-tender. Extremities: no deformity, distal PMS intact x4."

6. Diagnostic Findings Within Scope:

   • BLS-level findings such as blood glucose, pulse oximetry, and where carried, automated blood pressure.
   • Note when an ALS provider obtained advanced findings (for example a 12-lead ECG by the responding paramedic) and reference the ALS record rather than restating data outside your scope.
   • Example: "Blood glucose 110 mg/dL. 12-lead obtained by ALS intercept; interpretation documented in the ALS report."

7. Time Stamps:

   • Dispatch, en route, on scene, at patient, transport, and at destination times; intervention times.
   • Example: "Dispatched 0908, on scene 0911, at patient 0912, transport 0928, at destination 0941."

Tips:

• Record measured values, never estimates presented as measurements; if a value was not obtained, state why (for example "unable to obtain BP due to patient combativeness").
• Document at least two complete sets of vital signs whenever patient contact time allows; trends matter.
• Describe mechanism of injury objectively and concretely; it justifies your index of suspicion.
• Keep within your certification: attribute advanced findings to the ALS provider rather than restating them as your own.

Example of an Objective Section for EMS

Assessment Section (A)

The Assessment section is the EMS provider's field impression, the working clinical judgment that justifies the interventions performed and the transport decision. EMTs do not render definitive diagnoses; they document a reasoned impression supported by the subjective and objective findings.

Assessment Section (A) Components

1. Field Impression (Primary):

   • The most likely working problem based on the assessment.
   • Example: "Field impression: acute coronary syndrome, suspected cardiac chest pain."

2. Clinical Rationale:

   • The findings that support the impression.
   • Example: "Substernal pressure with radiation to the left arm and jaw, diaphoresis, history of prior MI, and risk factors support a cardiac etiology."

3. Differential Considerations:

   • Alternative explanations considered and why they are more or less likely.
   • Example: "Differential includes anginal equivalent, aortic dissection, and GI etiology; presentation most consistent with cardiac chest pain."

4. Acuity / Severity:

   • Stability of the patient and whether the condition is improving, stable, or deteriorating.
   • Trauma triage criteria or stroke/STEMI alert criteria when applicable.
   • Example: "Patient hemodynamically stable, symptoms improving after oxygen and aspirin; remains time-critical for cardiac evaluation."

5. Transport Decision and Medical Necessity:

   • Why transport (or non-transport) is appropriate, and to which destination per protocol.
   • The rationale that substantiates medical necessity for the level of service billed.
   • Example: "Patient meets criteria for emergency transport to the nearest PCI-capable facility; condition such that transport by other means would risk deterioration."

Tips:

• Frame the impression as a field judgment, not a definitive diagnosis ("suspected" or "consistent with").
• Connect each finding to your impression so the reasoning is transparent to the receiving clinician and a future reviewer.
• State the destination decision and the protocol or alert criteria that drove it.
• Make the medical-necessity rationale explicit; the narrative is what defends the A-code billed.

Example of an Assessment Section for EMS

Plan Section (P)

The Plan section documents what the EMS crew did, how the patient responded, and how care was handed off. In EMS this section is largely retrospective (interventions already performed in the field) and must pair every intervention with a reassessment. It also closes the record with transfer of care.

Plan Section (P) Components

1. BLS Interventions Performed (with times and response):

   • Oxygen (device and flow rate), airway maneuvers and adjuncts (OPA, NPA, suction), assisted ventilation with BVM.
   • Hemorrhage control (direct pressure, tourniquet with application time, wound packing).
   • Splinting, spinal motion restriction, positioning, warming/cooling.
   • CPR and AED use (compressions, shocks delivered with times, ROSC if achieved).
   • Example: "0914 oxygen at 4 L/min via nasal cannula; SpO2 improved from 95% to 99%."

2. Assisted / Administered Medications Within Scope:

   • Assistance with the patient's own prescribed medications or BLS-protocol medications (for example aspirin for suspected cardiac chest pain, oral glucose, the patient's MDI, or epinephrine auto-injector), with dose, route, time, and response.
   • Note medications outside BLS scope as administered by the ALS provider and documented in the ALS record.
   • Example: "0916 aspirin 324 mg (four 81 mg chewable tablets) administered per chest pain protocol; patient tolerated without difficulty."

3. Reassessment:

   • Repeat vital signs and focused findings after interventions and at intervals appropriate to acuity.
   • Trend the response to treatment.
   • Example: "Reassessment at 0925 showed pain reduced from 8/10 to 4/10 and SpO2 99% on oxygen."

4. ALS Coordination / Intercept:

   • Whether ALS was requested, rendezvoused, or assumed care, and at what point.
   • Example: "ALS intercept assumed patient care en route at 0932 for advanced cardiac monitoring."

5. Transport:

   • Mode (emergency vs. non-emergency), destination and rationale, patient position, and monitoring en route.
   • Example: "Emergency transport to County PCI Center, patient in position of comfort, continuous reassessment en route."

6. Transfer of Care:

   • Receiving clinician (name or role), time, location, verbal report given, and patient condition at handoff.
   • Example: "Care transferred to ED triage RN at 0943; full verbal report provided; patient stable, pain 3/10."

7. Patient Refusal / AMA (when applicable):

   • Capacity assessment, risks of refusal explained, alternatives offered, witnesses, advice to call back, and signature obtained.
   • Example: "Patient with intact capacity declined transport after risks including death were explained; refusal witnessed and signed; advised to call 911 if symptoms recur."

Tips:

• Pair every intervention with a reassessment; an intervention with no documented response reads as if it was never evaluated.
• Document medication assistance precisely: drug, dose, route, time, and response, and keep it within BLS scope.
• For refusals, document capacity, informed risks, alternatives, and a witnessed signature; this is the single most protective narrative an EMT writes.
• Always document transfer of care to close the chain of custody and demonstrate care was not abandoned.

Example of a Plan Section for EMS

EMS Patient Refusal / AMA Documentation

Patient refusals carry the highest medical-legal exposure in EMS. The narrative must demonstrate that the patient had decision-making capacity, was informed of the specific risks, refused voluntarily, and was offered alternatives. The example below shows a defensible refusal narrative for a patient who declined transport.

AI-Assisted Documentation for EMS

As of 2025, 66% of healthcare providers use AI tools in their practice. For EMS, AI scribes can dramatically reduce the after-call documentation burden that contributes to crew fatigue and delayed unit availability, while preserving the structure a defensible PCR requires.

How AI Can Help with EMS Documentation

• Narrative drafting between calls: Dictate the run on a phone or tablet after clearing the hospital and let AI structure the SOAP/CHART narrative for review.
• Framework completeness: AI prompts for SAMPLE, OPQRST, primary survey, serial vitals, and transfer of care so nothing is omitted under time pressure.
• Faster unit turnaround: Reducing documentation time helps units return to service sooner.
• Consistency: Standardized terminology across crews and shifts.

EMS-Specific AI Considerations

What AI captures well:

• Chief complaint, history (SAMPLE/OPQRST), and events leading to the call
• Scene size-up and mechanism of injury narrative
• BLS interventions, patient response, and transfer-of-care handoff
• Patient education and refusal narratives

What requires careful review:

• Measured values: vital signs, blood glucose, SpO2, and times (verify exact numbers)
• Medication assistance: drug, dose, route, and time
• Scope of practice: ensure advanced findings are attributed to the ALS provider, not restated as BLS care
• Times: dispatch, on scene, transport, and at destination must match the CAD/ePCR record

Tips for Using AI with EMS Documentation

1. State measured values explicitly: "Blood pressure one fifty-six over ninety-four at zero nine twelve" rather than "blood pressure was elevated."
2. Verbalize interventions with response: "Oxygen at four liters per minute by nasal cannula, oxygen saturation improved from ninety-five to ninety-nine percent."
3. Dictate medication assistance precisely: "Assisted patient with three twenty-four milligrams of chewable aspirin at zero nine sixteen per chest pain protocol."
4. Verify times against the CAD/ePCR record before signing the generated narrative.
5. Review every AI-generated PCR narrative carefully before it enters the ePCR; the signature attests to its accuracy.
