Review the following events and system vulnerabilities related to hospital safety. Align each specific clinical or administrative scenario with its most accurate patient safety classification.
- Latent error (System vulnerability)An institutional policy mandates the use of lower-cost surgical marking pens that easily wash off during standard skin prep, predisposing teams to wrong-site surgery.
- Sentinel eventA hospitalized patient dies unexpectedly from asphyxiation after becoming wedged between the mattress and a defective bed side rail.
- Active error (Sharp-end failure)A hurried cross-covering intern manually calculates a medication dosage using pounds instead of kilograms, entering a supratherapeutic dose into the chart.
- Near miss (Close call)A nurse prepares to administer a contraindicated medication but recognizes the error during bedside barcode scanning and discards the syringe before patient contact.
Cevap
Latent error matches with the procurement of flawed surgical pens; Sentinel event matches with the unexpected bed rail asphyxiation; Active error matches with the intern's weight-based calculation mistake; Near miss matches with the intercepted contraindicated medication.
Each scenario maps to a distinct concept in the Swiss Cheese Model of accident causation and standard patient safety terminology. Latent conditions are organizational or structural defects at the blunt end. Active failures are point-of-care errors at the sharp end. A near miss is an intercepted error that did not reach the patient, while a sentinel event is a severe, unexpected outcome involving death or serious physical or psychological injury.
Adım Adım Çözüm
Anahtar Kavram
Classification of medical errors and safety events (e.g., latent vs. active errors, near misses, sentinel events) is foundational for root cause analysis and systems improvement.
