- Retained foreign bodies (RFBs) are a serious complication in surgeries, and this study examines both near-miss and actual RFB cases to identify effective prevention strategies.
- A review of incident reports over a decade revealed 106 near-miss events and 24 actual RFB events among nearly 50,000 surgeries, highlighting the need for improved preventive measures.
- Key findings stress that standardized counting, better staff communication, and the use of X-rays during and after surgery can help reduce the incidence of RFBs.
