The patient interview is the only conversation that an EMS provider has with all of his or her patients that will remain exactly the same no matter how many calls he or she runs in their career.

Signs and symptoms

Most conditions are described by their signs and symptoms. Signs are things that the EMS crew can see and symptoms are things the patient tells you. Examples of signs are:

• Broken arm
• Blood pressure is 150/100
• Respirations are 28
• The patient is febrile because they are hot to the touch
• The patient’s blood sugar is 500

Examples of symptoms are:

• The patient is experiencing chest pain
• The patient is experiencing shortness of breath
• The patient is experiencing dizziness

Ok, so what is the conversation?

The interview is always the same and follows a set pattern of questions. Questions that occur to the ambulance crew after this conversation would be referred to as a follow up question.

• Subjective – This is the patient’s chief complaint as defined in terms of onset, provocation, quality, radiation, severity, and time. The patient says they have chest pain, then the medics ask about OPQRST (onset, provocation, quality, radiation, severity, and time).
• Allergies – The patient is probably allergic to a medication. Having a drug allergy means that when the patient takes the medication they have an allergic reaction. Many patients will confuse a medications side effect with an allergy. Not a problem for the ambulance crew. Simply write down the allergy and what happens when they take the medication.
• Medications – Patients are prescribed numerous medications. The EMS crew should write down each medication, the dosage for each mediation, and how many times they take the medication per day. Having a good list of medications is important to the rest of the health care team.
• Previous medical history – Inquire about the patient’s medical history. What medical conditions are they being treated for? What surgeries have they had? Is the patient undergoing some sort of holistic health treatment such as exercising, special diet, or fasting?
• Last meal or oral intake – What was the last thing the patient ate. It doesn’t make that big of a deal most of the time, but if the patient needs surgery, the anesthesiologists are definitely going to want to know.
• Events preceding the complaint – What was the patient doing before they started experiencing the pain that led them to call 911?

Any question formulated after having this conversation would be referred to as a follow up question. Examples of follow up questions could be:

• Do you have any plans to kill yourself?
• Did you go back to the same doctor after the incident?
• Have you ever eaten octopus before?
