In the context of root cause analysis and quality improvement, hospital safety committees must appropriately classify adverse events to identify systems-level vulnerabilities and implement effectively tiered corrective actions. Match each of the following patient safety events or interventions with its correct classification.
- A resident accidentally orders 50 mg of intravenous metoprolol instead of 5 mg for a patient with rapid atrial fibrillation due to fatigue.Active error (Sharp-end failure)
- The hospital's computerized physician order entry interface groups sound-alike medications closely together without the use of tall-man lettering.Latent error (Blunt-end failure)
- The electronic prescribing system is redesigned so that it is impossible to sign an order for methotrexate without first selecting an appropriate indication.Forcing function (Strong system-level control)
- Following a near-miss medication event, the department sends an email memo to all clinical staff reminding them to double-check patient identification.Administrative rule (Weak system-level control)
Answer
Match the fatigue-induced dosing error to 'Active error', the poor medication layout to 'Latent error', the hard stop for prescribing to 'Forcing function', and the email memo to 'Administrative rule'.
Patient safety frameworks distinguish between sharp-end active errors made by frontline staff and blunt-end latent errors rooted in system design. Furthermore, corrective actions derived from Root Cause Analyses are tiered by effectiveness; forcing functions are strong controls that prevent errors by design, whereas administrative rules are weak controls relying on human vigilance.
