SAMPLE: A simple guide that saves time, protects patients

In a noisy ambulance or a bustling ER hallway, the patient history often isn’t something you have all day to gather. You need a quick, reliable framework that helps you zero in on what matters most for treatment decisions. SAMPLE is that framework. No fluff, just a concise checklist that covers the essentials. And yes, the letters form a memorable rhythm you’ll use again and again.

What SAMPLE stands for—and why each piece matters

Let me explain each component and how it guides your care.

• Signs and Symptoms

Signs are what you can observe—rever, pale skin, sweating, an anxious look. Symptoms are what the patient describes—pain in the chest, dizziness, shortness of breath. This dual view gives you a fuller picture. If the patient can’t tell you what they feel, signs help you infer what’s going on. If they can tell you, symptoms confirm or steer your thinking. In a tight call, recognizing both can change the course of treatment fast.

• Allergies

Allergies, especially to medications, are non-negotiables. You don’t want to administer something only to spark a dangerous reaction. If the patient can’t tell you, look for a medical alert tag or bracelet. A quick “Do you have any allergies?” can prevent a bad outcome and buys you time to choose safe alternatives.

• Medications

What meds is the patient taking now? This includes prescribed drugs, over-the-counter meds, herbal supplements, and vitamins. Some meds can mask symptoms or clash with the treatment you’re about to give. Knowing what they take helps you understand the current condition and anticipate potential interactions.

• Past Medical History

Prior illnesses, surgeries, chronic conditions, and recent hospitalizations shape what you expect to find and what to watch for. A person with diabetes, for example, who presents with fatigue and confusion demands a different approach than someone without diabetes. This history helps you interpret the present episode and anticipate complications.

• Last Oral Intake

When did the patient last eat or drink? This matters for procedures that involve anesthesia or rapid sequence intubation, and it can influence how you manage vomiting risk or aspiration. Even in non-surgical settings, knowing last intake helps you weigh timing for certain meds and tests.

• Events

What happened? When did it start? What were you doing when symptoms appeared? Was there a fall, a crash, or a sudden onset of chest pressure during activity? The sequence of events helps you identify the likely cause and the best next steps. It also helps the receiving team piece together the story more quickly.

How to gather SAMPLE efficiently in the field

• Start with a quick intro and a calm tone. A patient who feels heard tends to share information more clearly.

• Use open-ended prompts, then tighten with targeted questions. For example: “Tell me what you’re feeling.” Then, “Are you experiencing chest pain, shortness of breath, or dizziness?”

• Move in a logical order, but be flexible. If the patient is in shock or unresponsive, you’ll rely more on signs, then fill in the others as the situation allows.

• Watch for nonverbal cues. A patient might struggle to speak clearly, so you’ll lean more on signs and what a caregiver or bystander can add.

• Keep it short and repeat as needed. Revisit SAMPLE as the patient’s condition changes or as new information comes in. A concise history is a living document in the field.

Concrete example: SAMPLE in action with chest pain

Let’s walk through a scenario you might actually face. Paramedics roll up to a middle-aged man who’s clutching his chest, short of breath, sweating, and pale.

• Signs and Symptoms: The patient reports a squeezing chest pain that started 20 minutes ago, radiates to the left arm, with nausea. You note pale skin, diaphoresis, and mild confusion.

• Allergies: No known drug allergies listed on the patient’s ID bracelet. No reactions to latex noted in his records.

• Medications: He’s not carrying meds, but his wife mentions he recently started a new blood pressure pill two weeks ago. You’d want to confirm what exact medication that is when possible.

• Past Medical History: History of hypertension and high cholesterol. No prior surgeries noted in the brief history available.

• Last Oral Intake: He had a light breakfast about three hours ago; no recent heavy meals.

• Events: Pain began during morning activity after climbing stairs. There was no trauma, no fainting, and no drug use reported by bystanders.

With this SAMPLE snapshot, you can prioritize care: aspirin if not contraindicated, oxygen if hypoxic, nitroglycerin if BP allows and there’s no contraindication, and rapid transport with alert to the receiving hospital. The clinician uses SAMPLE not as a checklist in a vacuum, but as a guiding map that will adapt as the patient’s condition evolves.

Putting SAMPLE into the flow of EMS care

• It’s not just a one-and-done moment. SAMPLE should be revisited during transport and when new information comes to light. The patient who was able to tell you their meds at the door may forget to mention something on arrival. That’s ok—update as you learn more.

• It should fit with the ABCs (Airway, Breathing, Circulation). You want a cohesive picture that supports the immediate priorities, then follows with a well-informed plan.

• Documentation matters. A clean, readable SAMPLE note helps the ER team pick up where you left off. Clarity here can shave minutes off treatment and reduce the chance of repeating questions.

Common pitfalls—and how to avoid them

• Assuming a patient’s allergies without confirmation. If there’s any doubt, treat as non-allergic until proven otherwise, but don’t skip asking—an allergy note can be life-saving.

• Too much focus on a single element. It’s easy to fixate on the obvious symptom and miss the bigger picture. Keep all six components in view; the missing piece in one area can explain the rest.

• Not updating SAMPLE as conditions change. A patient’s status can shift rapidly. Reassess and amend each letter as needed so the care plan remains aligned with reality.

• Relying on memory alone. In the heat of the moment, people forget details. When possible, verify with family, bystanders, or medical IDs.

Why SAMPLE matters in EMS operations

• It standardizes information flow. With six key areas, you create a consistent, repeatable approach that teammates recognize instantly.

• It sharpen your clinical reasoning. By systematically collecting data, you’re less likely to miss critical clues and more likely to catch red flags early.

• It supports safe decision-making. Knowing allergies and medications, in particular, reduces risk and guides safe interventions.

• It helps the handoff. The receiving facility benefits from a concise, complete history, which speeds diagnosis and treatment.

A few words on tone and flow

You’re not just filling in a form; you’re setting the stage for the patient’s next steps. The rhythm of SAMPLE mirrors the rhythm of care: quick, clear, and adaptable. Sometimes a single detail—an allergy, a recent medication, or an event that seems minor—will turn out to be the linchpin. That’s not luck; that’s the value of a disciplined approach.

If you’re new to EMS, you’ll notice how this becomes second nature with time. The acronym gives you a mental checklist, but the real skill is listening—actively listening—and then weaving the answers into a coherent clinical picture. And yes, that takes practice, but the payoff is tangible: better decisions, faster actions, safer outcomes for patients.

A closing thought: keep SAMPLE close at hand, but keep it flexible

Think of SAMPLE as your baseline narrative, not a rigid script. It’s a living tool that grows with each call, changes with the patient’s status, and communicates with teammates across the chain of care. Ask the questions, gather the facts, and let the patient’s story guide the next steps. In the end, it’s a simple idea that makes a big difference.

If you’re curious to explore more scenarios, you’ll find that applying SAMPLE across different patient presentations—trauma, respiratory distress, abdominal symptoms, or sudden collapse—helps you stay calm under pressure and ready for what comes next. The goal isn’t to memorize a ritual; it’s to develop a dependable habit that keeps patients safe, from the first greeting to the handoff at the hospital.

Bottom line

SAMPLE isn’t a fancy technique; it’s a practical, reliable way to capture the essential history in the critical minutes after a patient call. Signs and Symptoms, Allergies, Medications, Past Medical History, Last Oral Intake, and Events together form a compact map that supports smart decisions and smooth teamwork. Use it, adapt it, and let it become part of your everyday EMS toolkit. Your patients—and your future self—will thank you for it.
