A healthcare network's Quality and Patient Safety Committee is conducting a retrospective analysis of several recent clinical incidents to identify systemic vulnerabilities and human factors. To properly direct their Root Cause Analysis (RCA) and continuous quality improvement efforts, the committee must correctly categorize the nature of each event. Match each of the following specific clinical scenarios to the most accurate patient safety taxonomy classification.
- A procurement decision replaces the hospital's standard intravenous pumps with a new model that features a non-intuitive decimal placement on its programming interface.Latent error
- An experienced intensive care nurse intends to administer 1 mg of epinephrine but inadvertently draws up 10 mg from an adjacent, visually identical vial due to end-of-shift fatigue.Active error (Skill-based slip)
- An intern encounters a rare metabolic disorder for the first time and formulates an incorrect treatment plan based on generalized, inapplicable physiological principles rather than consulting a specialist.Active error (Knowledge-based mistake)
- An unanticipated catastrophic intra-abdominal hemorrhage results in the unexpected death of an otherwise healthy 30-year-old patient twelve hours after an uncomplicated elective appendectomy.Sentinel event
- A lethal concentration of intravenous potassium is dispensed by the pharmacy, but the bedside nurse identifies the error during routine barcode scanning and halts the process before patient connection.Near miss
Answer
The correct matches differentiate between blunt-end systemic vulnerabilities (Latent error), sharp-end execution failures (Skill-based slips), sharp-end planning failures (Knowledge-based mistakes), catastrophic outcomes requiring immediate investigation (Sentinel events), and intercepted errors (Near misses).
The matching structure relies on understanding James Reason's Swiss Cheese model of accident causation. Latent conditions exist at the organizational level (procurement). Active errors occur at the sharp end by frontline staff and are subdivided by cognitive mechanism: slips (attention failures) vs. mistakes (knowledge/rule failures). Outcomes determine the remaining classifications: intercepted errors are near misses, and catastrophic patient harms are sentinel events.
