Root Cause Analysis of Na¹³¹I Contamination

Area of Science:

• Nuclear Medicine
• Radiopharmaceutical Safety
• Adverse Event Analysis

Background:

• Establishing causality for adverse events is crucial for prevention and requires thorough root cause analysis (RCA).
• Nuclear medicine therapeutic procedures utilize unsealed radioactive sources, introducing unique safety considerations.
• Sodium iodide (Na¹³¹I) is used for hyperthyroidism and thyroid cancer, available in capsule or liquid forms, each with distinct handling risks.

Purpose of the Study:

• To describe a root cause analysis conducted in a nuclear medicine department following a Na¹³¹I contamination event.
• To detail the events, immediate remedial actions, and subsequent corrective measures implemented.
• To evaluate the effectiveness of the implemented corrective actions in preventing recurrence.

Main Methods:

• Conducted a detailed root cause analysis following a specific incident of Na¹³¹I contamination.
• Documented the sequence of events leading to the incident.
• Identified immediate remedial steps and implemented corrective actions based on RCA findings.

Main Results:

• The RCA successfully identified the underlying causes of the Na¹³¹I contamination event.
• Specific corrective actions were implemented based on the RCA findings.
• The effectiveness of these corrective actions in preventing similar future events was assessed.

Conclusions:

• Identifying the root cause of adverse events is essential for effective prevention strategies.
• RCA in nuclear medicine must account for the specific risks associated with unsealed radioactive sources.
• Systematic implementation and evaluation of corrective actions are key to enhancing patient safety and minimizing contamination risks.
