You will learn about the SAMPLE and OPQRST mnemonics during EMT school, and the significance of obtaining this information during your patient assessment. It may not be an automatic failure during your NREMT practical exam if you do not ask some of these questions, but it may lead you to fail your exam (example: you give a medication the patient is allergic to).
EMT-OPQRST Assessment
During EMT school, you will learn about an assessment
mnemonic tool used called “OPQRST”. This is an assessment tool for a patient that is experiencing pain, and is information you will need to gather from the patient in certain situations. This assessment is especially useful for patients with possible cardiac problems. This is what OPQRST stands for:
- O- Onset
- P- Provokes/Palliates
- Q- Quality
- R- Radiates
- S- Severity
- T- Time
Onset
The “onset” of the pain is what the patient was doing when the pain started. For example, if the patient is experience chest pain, it is important to know if the patient was active (running, mowing the lawn, chopping wood, etc…) or inactive (sitting on the couch) when the chest pain started. Chest pain that is cardiac in nature is more likely to start when a person is active.
This question will also help you figure out if the pain is medical in nature, or if the person may be having pain due to some other reason. An example of this is a person experiencing chest pain that was recently lifting weights (possible muscle pain).
Example “Onset” Questions:
- What were you doing when the pain started?
- Were you active when the pain started?
- Was the pain sudden or was it gradual (chronic)?
Provokes/Palliates
Finding out if anything “Provokes” or “Palliates” the pain, is asking if anything makes it better or worse. A patient that is experiencing chest pain that gets better with rest, and worse with activity may be experiencing a cardiac event (angina, M.I.).
A patient that is experiencing chest pain that hurts more when you palpate their chest (also called reproducible pain, if it is similar to the pain they were feeling before palpation) is likely experiencing muscle pain.
Palpating the patient where they are experiencing pain may help determine if the patient is experiencing pain due to a medical issue, or if the pain is musculoskeletal in nature. There are some instances that you should minimize palpating the area or not palpate at all (i.e. possible Abdominal Aortic Aneurysm, possible DVT, etc…) due to the possibility of exacerbating the patient’s condition.
Example Provokes/Palliates Questions:
- Does anything make the pain better?
- Does anything make the pain worse?
- If they are experiencing chest pain, palpate the area and ask “Does this cause the same type of pain?”
Quality
The “quality” of a patient’s pain is asking them to describe the pain. Examples of this are:
- Dull Pain
- Sharp Pain
- Burning Pain
- Tearing Pain
- Crushing Pain
- Throbbing Pain
Gathering the “quality” of the pain helps determine what may be causing the pain. “Dull” painthat a patient cannot easily locate in their abdominal region may indicate pain from a hollow organ (stomach, bladder, etc…) while “sharp” pain in the same region may indicate pain from a solid organ “liver, kidney, etc…). “Burning” pain may indicate heart burn instead of a cardiac problem.
“Tearing” pain could indicate an aneurysm, and “Crushing” chest pain may indicate a cardiac problem. It is important to remember that people having a heart attack (M.I.) present in different ways. Someone who is not experiencing “crushing chest pain” may still be having an M.I.. Remember, these are just tools to provide clues to what is going on, not tools to “diagnose” in the field.
Example Quality Questions:
- Can You describe the pain for me?
- If they wont describe the pain with open ended questions, ask them closed ended questions
- Is the pain Dull? Sharp? Crushing? Tearing? Burning?
Radiates
Asking the patient if the pain is moving anywhere, or if they are having pain anywhere else is determining if the pain is “Radiating”. Examples of this is a person having a heart attack, with pain in their arm, jaw, or epigastric pain. Patients having pain in other parts of their body may be experiencing “referred pain”.
Example “Radiates” Questions:
- Can you feel the pain moving anywhere?
- Are you having pain anywhere else?
Severity
This is a question to find out the “Severity” of the pain they are having. This question is completely subjective, and you will be asking a patient to rate their pain on a scale of 0-10, with 10 being the most painful (I usually describe 10 as being the worst pain they can possibly imagine).
It wont take you long to discover how many people they will tell you that they are experiencing “10 out of 10” or “12 out of 10” pain, while they are looking at you straight faced, not grimacing at all in pain (not to sound mean, but I’ve been doing this long enough to know what “10 out of 10 pain” really looks like.
In much rarer occasions, you will get someone that looks like they are about to pass out from pain tell you that they are having “5 out of 10” pain.
Just keep in mind that this is only a tool to help you figure out what is going on, and a tool to help you figure out if their pain is getting better or worse with treatment. I have had some protocols of when to give a medication for certain pain severity (example: giving nitro for a certain “chest pain” severity).
Example “Severity” Questions:
- Can you rate your pain for me on a scale of 0-10, with 10 be the worst possible pain that you could imagine?
Time
You want to know how long the pain has been going on. Ask the patient when the pain started, and find out if the pain has been “constant” or “intermittent”. Sometimes a patient will call 911 for pain that has been going on intermittently for several weeks, that may have recently gotten worse. If a patient has been experiencing pain for a long period of time, you may need to ask more questions to find out if the patient’s pain may be caused by an injury.
“Intermittent” chest pain that gets worse during physical activity may indicate problems with the heart. Intermittent Abdominal pain that gets worse after eating a fatty meal may indicate a gallbladder issue.
Example “Time” Questions:
- How Long Has the pain been going on?
- Has the pain been constant or intermittent?
- Has the pain been the same severity for the entire time?
EMT-SAMPLE Assessment
A “SAMPLE” history is a mnemonic used in the medical field, and is a useful tool that is easy to remember for EMTs. The SAMPLE history is usually gathered during the secondary assessment during EMT school, after you have managed the patient’s ABCs (Airway, Breathing, Circulation), after you have managed any immediate life-threats during your primary assessment. Here is what SAMPLE stands for:
- S- Signs/Symptoms
- A- Allergies
- M- Medications
- P- Pertinent Medical History
- L- Last Oral Intake
- E- Events Leading up to Illness/Injury
Signs/Symptoms
Signs are what you can see (objective), and symptoms are what the patient is feeling (subjective). An Example of Signs are: Sweating, visible blood, vomit on the floor, etc… An Example of Symptoms are: Nausea, Headache, abdominal Pain, etc…
Even though the SAMPLE history is gathered during the secondary assessment during EMT school, you will obviously gather some of the Signs/Symptoms when you first arrive on scene.
Example “Signs/Symptoms” Questions:
- What is Bothering you today?
- What made you call 911 today?
- What Symptoms are you feeling? You may need to ask close ended questions
Allergies
Asking a patient if they have any allergies is very important during the patient assessment. The patient may need medication(s) during their treatment, and they may not be able to answer this question for long if they lose consciousness. The hospital you bring the patient to may not have any medical records for the patient, and will not know what the patient is allergic to if the patient can no longer answer this question when they arrive.
This question may also help indicate what is going on with the patient during a respiratory emergency (possible severe allergic reaction).
Example “Allergies” Questions:
- Do you have any allergies to Medications
- Are you allergic to anything else? (Bees, Food, etc…)
Medications
Ask the patient if they currently take any medications (prescription and OTC). During EMT school, your patient will likely be taking only a few medications.
When you are working on an Ambulance, many patients have a long list of medications that they are taking. If you are lucky, they will have a list of their medications written out for you that you can bring with you to the hospital. It may be best to put all of their medications into a bag and bring them with you to the hospital to save time.
If you are conducting a patient assessment, pay attention to what medications they tell you that they take. If they are having chest pain and currently take Nitroglycerin, ask them if they had taken any prior to your arrival (they may have already taken their maximum dose). Do this for any medication you are going to administer to make sure they have not reached their maximum dosage.
Pay attention to what medications you are going to give a patient and what their allergies are.Ask them what their allergies are before you ask for their medications.
Also if you are going to give Nitro, ask specifically if they have taken any Erectile Dysfunction Medications in the last 3 days (some of the medications last up to 3 days). I do this even if they don’t mention this while you are asking for their medications. Many patients do not want to tell you that they are taking E.D. medications; if you ask them this question directly, they are more likely to answer honestly because they realize you are asking it for a reason (emphasize its importance).
Example “Medications” Questions:
- Are you taking any prescription medications?
- Are you taking any over-the-counter (otc) medications?
- Have you taken any Erectile Dysfunction Medications in the last 3 days? (chest pain patients)
Pertinent Medical History
Try to gather the best medical history from the patient that you can. You are looking for a Significant medical history here (not if they sprained their ankle 20 years ago). “Pertinent” means relevant to their current condition, but I recommend you try to gather their “significant” medical history (it is possible that you will not know what is pertinent). Don’t expect the patient to know what is significant or not, and be ready to ask closed ended questions.
For example, I recently hooked up a patient with a heart rate of 140 up to my cardiac monitor, and the patient was in A-fib (atrial Fibrillation); I asked the patient if he “had a history of A-Fib”, and he said “No”. I then asked him if he had “any heart problems”, and he said “no”. I then asked him if he had any “history of an irregular heartbeat”, and he said “yes”. The point of this is that many patients don’t know what their condition is called, or are very knowledgeable about it.
If you ask a question if they have any “significant” medical history, or “pertinent” medical history, many times they will tell you no. Be Prepared to ask “close ended” questions to gather their pertinent history. During your EMT exam, when you ask for the “pertinent history”, the person testing you will tell you their whole medical history when you ask, but this is not what happens in the real world. Many times, a patient’s medications will provide better clues to the patient’s medical history than the patient can tell you.
Example “Pertinent Medical History” Questions:
- Can you tell me your medical history?
- Do you have any serious medical problems?
- Do you have any problems with your heart?
- Do you have any problems with your lungs?
- Do you have any history of an “irregular” heartbeat?
- Do you have Diabetes?
- Do you have a history of Hypertension?
- Do you have a history of COPD?
- Do you have a history of CHF?
- Have you ever had a Stroke? TIA?
- Have you ever had a Heart Attack?
- Surgical History?
- Have you been hospitalized recently?
Last Oral Intake
Ask the patient the last thing they ate/drank. This may provide clues to their illness. For example, someone with chest pain that just ate some spicy food may be experiencing heartburn. Someone with abdominal pain that just ate a fatty meal may be having gallbladder issues.
The Last Oral intake can also provide you clues for patients who have food poisoning, an allergic reaction, or that are hypotensive (inadequate hydration can lead to hypotension).
If the patient has not been eating or drinking much because they are nauseated, this can lead to further problems. Also ask the patient about their urinating/bowel movements.Nausea/Vomiting/Diarrhea can lead to dehydration. If the person has not been urinating, that can indicate dehydration as well.
Example “Last Oral Intake” Questions:
- What was the Last thing you ate?
- What was the Last thing you drank?
- Have you been eating and/or drinking adequately the last few days?
Events Leading up to Illness/Injury
It is important to know what the patient was doing leading up to their illness or injury.
When a patient is having chest pain, you should ask them what they were doing when the pain started; if they were active at this time (example: running), it is more likely to be cardiac related then if they were inactive (watching t.v.).
If they are having pain anywhere, (example: pain in their right leg” it will help you provide clues to why the pain started. If they are having pain after doing a leg work-out, it is probably muscle pain or an injury. If they were just sitting on the couch, and had not had an injury, you may suspect a medical reason for the pain (possible DVT, etc…).
Example “Events Leading to Illness/Injury” Questions:
- What were you doing when the Pain/Symptoms Started?
- When did the Illness/Injury Start?
Conclusion
Try to gather a SAMPLE history for every patient that you assess (unless you cannot move past the ABCs because they are not intact), and an OPQRST assessment for any patient experiencing pain. As a first responder to the patient, you may be the only person that has the opportunity to ask the patient these questions (if they lose consciousness).This information can be very valuable to an ALS intercept, or the receiving hospital.
