Lesson Notes

Read through the key concepts before you try the challenge.

The history is most of the diagnosis

On the job

You room a patient at Lakeside Medical Associates.

You ask 'so it's just the usual back pain?' and the patient agrees, because agreeing is easier than correcting you. The actual complaint was new numbness in one leg. Your question offered an answer, and the patient took it.

Your task: Ask questions that let the patient tell you what is actually happening.

A well-taken history contributes more to diagnosis than any single test. The medical assistant usually takes the first pass at it, which means the quality of your questions shapes what the provider starts from.

Type	Example	Use for
Open-ended	What brings you in today?	Opening a topic; letting the patient lead
Closed	Are you taking any blood thinners?	Confirming specific facts
Clarifying	When you say dizzy, do you mean the room spins, or that you feel faint?	Pinning down vague terms that mean different things
Leading — avoid	The pain isn't radiating down your leg, is it?	Nothing. It suggests the answer you expect

Question types and when to use each

Start open and narrow down. Opening with a closed or leading question constrains what the patient tells you before they have said anything, and patients frequently accept the framing offered rather than correcting a clinician.

Component	Captures
Chief complaint	Why they came, in their own words
History of present illness	Onset, location, duration, character, aggravating and relieving factors, timing, severity
Past medical history	Prior conditions, surgeries, hospitalizations
Medications	Prescription, over-the-counter, supplements — all of them
Allergies	The allergen and the specific reaction
Family history	Conditions in close relatives
Social history	Tobacco, alcohol, substances, occupation, living situation

Components of a medical history

Record the chief complaint in the patient's own words, in quotation marks. 'My chest feels tight when I walk up stairs' is data. 'Angina' is your interpretation, and it is a diagnosis you are not authorized to make — it may also be wrong, and once it is in the record it colors everything that follows.

Allergies need the reaction, not just the substance. 'Penicillin — hives and throat swelling' is clinically different from 'penicillin — upset stomach,' which is an intolerance rather than an allergy. Recording only the drug name can unnecessarily rule out an entire antibiotic class for a patient's whole life.

Check your understanding

A patient says they feel 'dizzy.' What is the most useful next question?

Challenge

Apply what you've learned in this lesson.

Interviewing is a skill you build by doing it badly and noticing.

Rewrite each as an open-ended or clarifying question: 'You're here for your diabetes follow-up, right?' 'The medication is working okay?' 'No new symptoms?'
Research the OLDCARTS or SOCRATES mnemonic for history of present illness. Write out what each letter prompts.
For a patient reporting 'stomach pain,' write eight questions that would characterize it fully, using at least two clarifying questions.
Practice a five-minute intake with someone willing to role-play. Afterwards, count how many of your questions were leading.
