Effective Medical History Taking

Introduction to Medical History

  • The American Academy of Physicians recommends establishing rapport in a comfortable environment and systematically gathering information starting with the chief complaint using open-ended questions, followed by structured collection of past medical history, medications, family history, social history, and review of systems—all while maintaining active listening and documenting the patient's narrative in their own words 1

Creating the Right Environment and Establishing Rapport

  • The American Medical Association suggests introducing yourself and explaining the purpose of the history-taking session to set clear expectations with the patient 1
  • Position yourself with appropriate body language by orienting your lower body toward the patient and maintaining eye contact to demonstrate engagement 1
  • Establish confidentiality parameters at the beginning, particularly important for adolescents and when discussing sensitive topics 1

Systematic Approach to History Collection

  • The American College of Physicians recommends starting with open-ended questions allowing the patient to tell their story in their own words without interruption 1, 2
  • Document the patient's narrative in sufficient detail to accurately retell their story, including the patient's own words when describing symptoms 1, 3
  • For every presenting complaint, systematically document: onset and chronology, location, quality, severity, duration, context, and modifying factors 2
  • The American Academy of Ophthalmology suggests asking about time of day when symptoms worsen (morning worsening suggests certain conditions like blepharitis, while evening worsening suggests others like aqueous deficient dry eye) 4

Past Medical History

  • The American Heart Association recommends obtaining a thorough cardiovascular history including myocardial infarction, arrhythmia/atrial fibrillation, coronary procedures (angioplasty, stent, bypass), pacemaker, congestive heart failure, angina, and peripheral artery disease 5
  • Document cerebrovascular disease including stroke (hemorrhagic or ischemic), transient ischemic attack, and endarterectomy 5
  • The Infectious Diseases Society of America suggests asking about chronic conditions: diabetes mellitus, hypertension, hyperlipidemia, renal disease, chronic viral hepatitis, peripheral neuropathy, gastrointestinal disease 6, 5

Medication History

  • The American Medical Association recommends documenting all prescription medications including names, dosages, frequencies, and duration of use 2
  • Include over-the-counter medications, methadone, dietary supplements, and herbal remedies—some interact with prescription drugs 6, 2

Family History

  • The American College of Medical Genetics recommends obtaining a three-generation family history focusing on first-degree relatives with relevant conditions 2
  • Document history of stroke, vascular disease including myocardial infarction, dementia, and other neurological diseases in first-degree relatives 5, 7

Social History

  • The American Academy of Pediatrics suggests documenting substance use including tobacco, alcohol, heroin, marijuana, cocaine, and other recreational drugs 6, 5, 2
  • Record occupational history and environmental exposures (second-hand smoke, pesticides, medications) 5, 2

Review of Systems

  • The American College of Physicians recommends conducting a comprehensive symptom review covering: constitutional, HEENT (head/eyes/ears/nose/throat), cardiovascular, respiratory, gastrointestinal, genitourinary, musculoskeletal, dermatologic, and neurologic symptoms 2
  • Document pertinent negatives to demonstrate thoroughness 2

Special Communication Techniques

  • The American Medical Association suggests practicing active listening by maintaining eye contact, nodding, and providing verbal acknowledgment 1
  • Use motivational interviewing techniques for sensitive topics or when addressing health behavior change 1

Population-Specific Considerations

  • The American Academy of Pediatrics recommends considering seeing adolescents alone for part of the interview and using developmentally appropriate approaches 1
  • The American Geriatrics Society suggests taking extra time and being aware of higher risk for medication errors when interviewing elderly patients 1

Documentation Best Practices

  • The American Health Information Management Association recommends using clear language and documenting the source of information 2
  • Use macros and templates appropriately for standardized sections like review of systems, but avoid "copy/paste" of entire notes without editing as this propagates errors 3
  • Include the patient's own words when documenting symptoms or concerns 1, 3

Medication History Accuracy and Safety

Importance of an Accurate Medication History

  • Obtaining a precise medication history is a critical component of patient safety and helps prevent prescription errors. 8

Comprehensive Documentation of Drug Allergies and Intolerances

  • Detailed recording of drug allergies—including the specific dose, nature of the reaction, temporal relationship to the drug, and any susceptibility factors—is essential for safe prescribing. 8

Role of Pharmacy Professionals in Reducing Medication Errors

  • Pharmacists consistently acquire more complete medication histories than physicians and their involvement during acute admissions reduces both the rate and severity of medication errors; therefore, involving pharmacy staff when available is recommended. 8
