Which information is typically included in Past Medical History (PMH) and why is it critical for risk assessment?

• A. Chronic diseases, prior illnesses, surgeries, hospitalizations, chronic medications.
• B. Vaccination status only.
• C. Social habits only.
• D. Family history only.

Answer: (D)

Past Medical History centers on what the patient has already experienced that affects current health risk. It includes chronic diseases, prior illnesses, surgeries, hospitalizations, and chronic medications. This information reveals the patient’s established health burden, how organ systems have been affected, and what therapies the patient is already dependent on, all of which shape current risk. Why this matters for risk assessment: knowing chronic diseases (like diabetes or heart disease) helps predict complications and guide treatment choices; prior surgeries can influence anesthesia planning and potential adhesions or scar tissue; past hospitalizations flag underlying fragility or recurrent problems; and chronic medications alert you to drug interactions, contraindications, or altered organ function. Together, these details establish the patient’s baseline risk and inform prognosis and management. Vaccination status, social habits, and family history are important pieces of the broader history, but they belong to different sections: vaccination status and social habits are preventive and social history, while family history informs inherited risk and is categorized separately from PMH.
