Are we missing the near misses in the OR?-underreporting of safety incidents in pediatric surgery.

BACKGROUND: Electronic hospital variance reporting systems used to report near misses and adverse events are plagued by underreporting. The purpose of this study is to prospectively evaluate directly observed variances that occur in our pediatric operating room and to correlate these with the two established variance reporting systems in our hospital.
MATERIALS AND METHODS: Trained individuals directly observed pediatric perioperative patient care for 6 wk to identify near misses and adverse events. These direct observations were compared to the established handwritten perioperative variance cards and the electronic hospital variance reporting system. All observations were analyzed and categorized into an additional six safety domains and five variance categories. The chi-square test was used, and P-values < 0.05 were considered statistically significant.
RESULTS: Out of 830 surgical cases, 211 were audited by the safety observers. During this period, 137 (64%) near misses were identified by direct observation, while 57 (7%) handwritten and 8 (1%) electronic variance were reported. Only 1 of 137 observed events was reported in the handwritten variance system. Five directly observed adverse events were not reported in either of the two variance reporting systems. Safety observers were more likely to recognize time-out and equipment variances (P < 0.001). Both variance reporting systems and direct observation identified numerous policy and process issues.
CONCLUSIONS: Despite multiple reporting systems, near misses and adverse events remain underreported. Identifying near misses may help address system and process issues before an adverse event occurs. Efforts need to be made to lessen barriers to reporting in order to improve patient safety.
