Following a near-miss incident involving an improperly loaded decentralized automated medication dispensing system on an inpatient ward, a hospital's patient safety committee decides to proactively evaluate the entire medication dispensing workflow. The goal is to systematically identify and mitigate system vulnerabilities before a harmful medication error occurs by conducting a Failure Mode and Effects Analysis (FMEA). Arrange the procedural steps of the FMEA process in the correct chronological sequence from start to finish.
- 1Assemble a multidisciplinary team to define and map the new medication dispensing process.
- 2Identify all potential failure modes for each step in the newly mapped process.
- 3Calculate the risk priority number (RPN) for each potential failure mode.
- 4Develop and implement targeted risk reduction strategies for the highest-scoring vulnerabilities.
- 5Reassess the system post-implementation to verify that the identified risks have been effectively mitigated.
Answer
The correct chronological sequence for a Failure Mode and Effects Analysis (FMEA) is: 1) Assemble the team and map the process, 2) Identify potential failure modes, 3) Calculate risk priority numbers, 4) Implement targeted interventions, and 5) Reassess the system post-implementation.
Failure Mode and Effects Analysis (FMEA) follows a structured, proactive sequence. It begins by assembling a multidisciplinary team to comprehensively map a high-risk process. The team then brainstorms potential failure modes at each step of that mapped process. Next, a risk priority number (RPN) is calculated by multiplying the severity, occurrence, and detectability of each specific failure mode. The highest RPNs guide the development and implementation of targeted, system-level interventions. Finally, the process is reassessed to ensure the interventions successfully reduced the targeted vulnerabilities.
Step-by-Step Solution
Key Concept
Failure Mode and Effects Analysis (FMEA) is a prospective, systematic quality improvement framework used to identify, prioritize, and mitigate process vulnerabilities before an adverse event reaches a patient.
