Failure mode and effects analysis: too little for too much?

Area of Science:

• Healthcare Risk Management
• Patient Safety
• Quality Improvement

Background:

• Failure Mode and Effects Analysis (FMEA) is a widely adopted prospective risk assessment method in healthcare.
• FMEA utilizes multidisciplinary teams to identify potential process failures, their likelihood, severity, and detectability.
• The goal is to calculate a Risk Priority Number (RPN) to guide interventions.

Purpose of the Study:

• To evaluate the evidence base for the reliability and validity of FMEA outputs in healthcare.
• To examine the mathematical principles underlying FMEA's Risk Priority Number (RPN) calculation.
• To assess the practical application and time investment of FMEA in clinical settings.

Main Methods:

• Systematic review of existing literature on FMEA in healthcare.
• Analysis of the methodologies and reported outcomes of FMEA studies.
• Critical appraisal of the quantitative aspects and practical utility of FMEA.

Main Results:

• Despite widespread use, there is limited empirical evidence supporting FMEA's reliability and validity for quantitative risk prioritization.
• The mathematical basis for RPN calculation is questionable, and its application varies significantly in practice.
• FMEA is resource-intensive, requiring substantial healthcare professional time.

Conclusions:

• FMEA is not recommended as a quantitative tool for prioritizing patient safety interventions due to lack of evidence.
• The process mapping and multidisciplinary team engagement stages of FMEA are valuable.
• Further research is needed to develop effective methods for translating FMEA's process mapping into actionable patient safety plans.
