FMEA: A Step-by-Step Guide for CPHQ Candidates

Failure Mode and Effects Analysis (FMEA) is a proactive risk assessment tool that the CPHQ exam tests frequently. Unlike root cause analysis, which is reactive, FMEA identifies potential failures before they occur.

When to Use FMEA

Use FMEA when designing a new process, modifying an existing process, or when you want to proactively identify and mitigate risks. The Joint Commission requires a proactive risk assessment annually, and FMEA is the most common method used.

The FMEA Process

Step 1: Select a high-risk process. Use data to identify processes with the highest potential for patient harm.

Step 2: Assemble a multidisciplinary team that includes people who work in the process daily.

Step 3: Map the process steps. Create a detailed flowchart of every step in the process.

Step 4: Identify failure modes for each step. Ask "what could go wrong?" at every point.

Step 5: Rate each failure mode on three scales: Severity (impact if it occurs), Occurrence (likelihood of happening), and Detection (likelihood of catching it before reaching the patient).

Step 6: Calculate the Risk Priority Number (RPN) by multiplying Severity x Occurrence x Detection. Higher RPNs indicate higher priority for action.

Step 7: Develop action plans for the highest-priority failure modes. Implement changes and remeasure.

Key Exam Points

Remember: FMEA is proactive (before events happen), RCA is reactive (after events happen). The three rating dimensions (Severity, Occurrence, Detection) are commonly tested. High severity with low detectability is particularly dangerous.
