Medical Error Disclosure

• Disclose the facts: what happened, what the consequences are, what is being done about it, and what will be done to prevent recurrence. An apology is appropriate; many states have laws that prevent expressions of sympathy from being used as an admission of liability.
• Disclose even errors that caused no harm if they are material to the patient's care or future decisions. Near-misses go to the institutional reporting system.
• Do not blame colleagues or speculate about fault in the disclosure conversation.
• An error made by another physician should first be discussed with that physician, encouraging them to disclose; if they will not and the patient was harmed, escalate through institutional channels.
• Reporting is separate from disclosure: errors go to the institution's patient safety system, which analyses them through root cause analysis in a non-punitive, systems-focused frame. Blaming individuals suppresses reporting and is the wrong answer to "how should the hospital respond?"

Core definitions

• Medical error: a failure of a planned action to be completed as intended, or use of a wrong plan (the To Err Is Human framing from the Institute of Medicine, now the National Academy of Medicine). Error is defined by the process, not by the outcome.
• Adverse event: harm caused by medical care rather than the underlying disease. It may be preventable (error-related) or non-preventable (e.g., a first-time anaphylactic reaction to an appropriately chosen drug).
• Near miss (close call): an error that reached no patient or reached the patient without harm. Reported internally; generally not disclosed unless material to future care.
• Sentinel event (The Joint Commission): a patient safety event resulting in death, permanent harm, or severe temporary harm. It obligates the organization to perform a comprehensive systematic analysis (root cause analysis) and implement an action plan.
• Never event: a serious, largely preventable event from the National Quality Forum's Serious Reportable Events list — wrong-site surgery, retained foreign body, ABO-incompatible transfusion. CMS declines additional payment for several related hospital-acquired conditions.

Why errors happen

• Swiss cheese model (Reason): harm occurs when holes in successive layers of defense align. Active errors are committed at the sharp end by the person touching the patient; latent errors are upstream system flaws — understaffing, look-alike packaging, poor handoffs.
• Slips and lapses are failures of execution or memory in an automatic task; mistakes are failures of planning — the wrong intention correctly carried out.

Analytic tools

• Root cause analysis: retrospective, reactive, asks why did this happen? using repeated "why" questioning to reach system causes.
• Failure mode and effects analysis: prospective, asks what could go wrong? before a process is deployed.
• Just culture: distinguishes human error (console, fix the system), at-risk behavior (coach), and reckless behavior (discipline). Non-punitive does not mean non-accountable.
• Legal scaffolding: the Patient Safety and Quality Improvement Act of 2005 confers privilege on patient safety work product reported to Patient Safety Organizations; state apology laws shield expressions of sympathy, though many do not shield explicit admissions of fault.

• Stabilize first: clinical rescue precedes every ethical step. Give dextrose (IV D50 or glucagon if no access), recheck glucose, monitor. A stem that offers "disclose the error to the patient" while the patient is still hypoglycemic is testing sequencing.
• Then disclose, promptly and personally: the physician responsible for the patient's care explains what happened, what it means clinically, that the team is sorry, and what will be done to prevent recurrence. Per the AMA Code of Medical Ethics, disclosure is owed regardless of whether the patient would ever have discovered the error.
• Do not wait for the patient to ask, route the conversation through risk management alone, or tell the family instead of a decisional patient.
• Then report into the institutional patient safety/incident system. Disclosure and reporting are parallel duties, not substitutes.
• Then analyze: root cause analysis will likely surface latent causes — a "U" misread as a zero, absent dosing alerts, no independent double-check for high-alert medications. The correct institutional response is a system fix (prohibit the "U" abbreviation, hard-stop order limits), not suspending the intern.

Variant stems

• Another physician's error: approach that colleague first and encourage self-disclosure; if they refuse and the patient was harmed, escalate to the supervising physician, chief of service, or patient safety committee. Do not confront them in front of the patient, and do not tell the patient "Dr. X made a mistake."
• Error with no harm and no future relevance (wrong-rate IV fluid caught immediately): still report internally; disclosure is judgment-based and hinges on materiality.
• Patient asks "was this a mistake?": answer truthfully with the known facts and avoid speculating about causation before the analysis is complete.

• The single best next step after a harmful error is prompt, direct disclosure by the responsible physician — after the patient is medically stabilized. Stabilization first, disclosure second, reporting third, analysis fourth.
• Apology is expected, not forbidden. The classic distractor is that saying "I'm sorry" is a legal admission; most states have apology statutes protecting expressions of sympathy, and communication-and-resolution programs such as AHRQ's CANDOR are associated with less litigation, not more.
• Disclosure ≠ reporting. Disclosure goes to the patient; reporting goes to the institutional patient safety system and, when applicable, a Patient Safety Organization with federal privilege under the 2005 Patient Safety and Quality Improvement Act.
• Root cause analysis is retrospective and systems-focused; failure mode and effects analysis is prospective. If the stem says "before implementing the new chemotherapy ordering process," the answer is FMEA.
• "Blame the individual" is always wrong for the institutional response. Punitive culture suppresses reporting. But just culture still disciplines reckless behavior — non-punitive is not the same as consequence-free.
• Sentinel event (Joint Commission) triggers mandatory internal analysis and action plan; never event (National Quality Forum serious reportable events) includes wrong-site surgery, retained foreign object, and ABO-incompatible transfusion, and CMS withholds additional payment for related hospital-acquired conditions.
• A colleague's error: talk to the colleague first and encourage them to disclose; escalate through institutional channels only if they refuse and the patient was harmed. Never disclose on their behalf as your first move, and never disparage them to the patient.
• Active vs latent error is a favorite distinction: the nurse who hangs the wrong bag committed the active error; the pharmacy that stocked two look-alike bags side by side is the latent error — and the latent error is what the corrective action must target.
