Chart biopsy
Formal Definition
A colloquial expression describing the focused, fast review of a patient's medical record — typically before a new consultation, before an unfamiliar admission, or for an emergency patient — to extract only the immediately relevant facts such as active problem list, recent hospitalizations, current medications, allergies, code status, social history, and pertinent prior workup; analogous to a pathologic biopsy in that it samples only what's needed rather than reading the chart in full, useful when time is constrained and the comprehensive chart review can come later.
How It's Used on the Ward
"Doing a chart biopsy" or "I'll chart-biopsy this patient" — when a consultant has 8 patients to see in 2 hours and a brand-new consult just hit the list, the consultant opens the chart, scans the recent notes, the problem list, the allergies, the recent admissions, and gets the headline picture in 5 minutes; full review comes later if needed for the consult question.
Example
""Cardiology fellow receives a new consult at 10 AM for an EKG abnormality on a patient they have never met. Fellow: 'I'll chart-biopsy her before going to the bedside.' Opens the chart: 78-year-old female, problem list includes HTN, CKD stage 3, paroxysmal afib (on apixaban), HFrEF (EF 35% from 2 months ago). Allergies: lisinopril (cough). Meds: metoprolol succinate 50 mg, furosemide 40, apixaban 5 BID, spironolactone 25. Last admission: 3 months ago for CHF exacerbation. New EKG today: 'Atrial fibrillation with slow ventricular response, rate 48, no acute ST changes' (compared to prior with RVR). Patient on metoprolol monotherapy. Consult question: rate-control strategy — likely metoprolol dose adjustment vs addition of diltiazem, hold apixaban dose-check given rate.""
Clinical Context
Useful when: (1) New consult, unfamiliar patient, time pressure. (2) ED admission with unknown history. (3) Cross-cover on a patient you've never met. (4) Pre-rounds in the morning when the team has 20 patients. What to extract: name, MRN, age, code status, allergies (allergen + reaction type), active problem list, current meds, recent vitals and labs, most recent discharge summary, most recent relevant note (cardiology if CHF, nephrology if CKD, etc.), recent imaging relevant to current question. What NOT to do with a chart biopsy: skip the full review when there is time and complexity warrants it. A chart biopsy is fast scanning to function clinically; the comprehensive chart review catches subtleties (e.g., a previous allergic reaction that doesn't appear in current allergies list, a remote surgical history that affects differential, a family history that changes the picture). Related phrases: "chart pre-round," "needs chart review," "I'll get to know this patient."
