How does Failure Modes and Effects Analysis (FMEA) differ from RCA, and when is it used in medication safety?

• A. FMEA is post-event analysis; RCA proactive; used to reduce costs.
• B. FMEA focuses only on labeling; RCA only on dosing.
• C. FMEA is proactive to identify potential failures before they occur; RCA is reactive after an event; used to prevent harm in high-risk processes.
• D. FMEA replaces human oversight; RCA does not.

Answer: (C)

FMEA is a proactive risk assessment used to identify potential failure points in a medication-use process before any error occurs and to put safeguards in place to prevent harm. In medication safety, this means examining steps from prescribing to administration, pinpointing where things could go wrong (such as incorrect dosing, look-alike/sound-alike drugs, or labeling errors), and designing controls—like barcoding, double checks, standardized protocols, or automation—to stop problems before they happen. RCA, on the other hand, is a reactive investigation conducted after an adverse event or near-miss to uncover root causes and contributing factors and to prevent recurrence. The combination is powerful in high-risk processes: use FMEA to prevent harm ahead of time, and use RCA to learn from incidents and strengthen the system when something goes wrong. The statement that best reflects this distinction is that FMEA is proactive to identify potential failures before they occur, while RCA is reactive after an event and used to prevent harm in high-risk processes.
