Implementation of the failure modes and effects analysis in a Hospital Radiopharmacy Unit.

Area of Science:

• Nuclear Medicine
• Radiopharmacy Practice
• Healthcare Risk Management

Background:

• Hospital radiopharmacies manage complex processes for radiopharmaceutical preparation and administration.
• Proactive risk identification is crucial for ensuring patient safety and optimizing radiopharmaceutical workflows.

Purpose of the Study:

• To implement a risk analysis methodology, specifically failure modes and effects analysis (FMEA), within a hospital radiopharmacy unit.
• To proactively identify potential failure modes in radiopharmaceutical processes and prioritize corrective actions.

Main Methods:

• Failure Modes and Effects Analysis (FMEA) was applied to prescription, preparation, and administration stages of diagnostic and therapeutic radiopharmaceuticals.
• Risk Priority Number (RPN) was calculated based on severity, probability, and detectability to quantify risks.
• Improvement measures were proposed, and their potential impact on RPN was evaluated.

Main Results:

• 96 failure modes were identified, with patient-radiopharmaceutical identification having the highest RPN (60) and radiolabeling cell sub-process the highest risk (RPN 286).
• Implemented measures reduced overall RPN by 22% for diagnostic and 20% for therapy radiopharmaceuticals.
• Potential implementation of radiopharmacy software and barcode technology could further reduce RPN by 46% and 31%, respectively.

Conclusions:

• FMEA is an effective tool for identifying critical control points in radiopharmaceutical processes.
• Risk analysis and prioritization of corrective measures are essential for enhancing safety in radiopharmacy operations.
