Safety in the operating room during orthopedic trauma surgery—incidence of adverse events related to technical equipment and logistics

Background Safety in the operating room is widely debated. Adverse events during surgery are potentially dangerous for the patient and staff. The incidence of adverse events during orthopedic trauma surgery is unknown. Therefore, we performed a study to quantify the incidence of these adverse events. Primary objective was to determine the incidence of adverse events related to technical equipment and logistics. The secondary objective was to evaluate the consequences of these adverse events. Methods We completed a cross-sectional observational study to assess the incidence, consequences and preventability of adverse events related to technical equipment and logistics during orthopedic trauma surgery. During a 10 week period, all orthopedic trauma operations were evaluated by an observer. Six types of procedures were differentiated: osteosynthesis; arthroscopy; removal of hardware; joint replacement; bone grafting and other. Adverse events were divided in six categories: staff dependent factors; patient dependent factors; anaesthesia; imaging equipment; operation room equipment and instruments and implants. Adverse events were defined as any factor affecting the surgical procedure in a negative way. Results Hundred-fifty operative procedures were included. In 54% of the procedures, at least one adverse event occurred. In total, 147 adverse events occurred, with a range of 1–5 per procedure. Most adverse events occurred during joint replacement procedures. Thirty-seven percent of the incidents concerned defect, incorrect connected or absent instruments. In 36% of the procedures adverse events resulted in a prolonged operation time with a median prolongation of 10.0 min. Conclusion In more than half of orthopedic trauma surgical procedures adverse events related to technical equipment and logistics occurred, most of them could easily be prevented. These adverse events could endanger the safety of the patient and staff and should therefore be reduced. Level of evidence 4.
