Abstract
PURPOSE: To mitigate intraoperative adverse events, it is important to understand the context in which these errors occur. The purpose of this study is to characterize the IAEs and potential distractions that occur in minimally invasive urologic procedures. METHODS: We conducted a prospective cohort study in patients undergoing laparoscopic urologic surgery at an academic health center. The OR Black Box, a unique technology system which captures video and audio recordings of the operating room as well as the operative field, was used to collect data regarding procedure type, critical step, IAEs, and distractions. RESULTS: Of a total of 80 cases analyzed, the majority of these cases were partial nephrectomy (n = 36; 45%), radical nephrectomy (n = 20; 25%), and adrenalectomy (n = 4; 5%). Across all cases, there were a total of 138 clinically significant IAEs, 10 of which (14%) were of the highest severity (five on the SEVerity of intraoperative Events and Rectification Tool (SEVERE) matrix). Of these, 70 (51%) occurred during an a priori defined critical step of the operation. Distractions were common across all cases. The median rate of external communication per case was 16 events (IQR 11-22); and per critical step was 4 (IQR 2.75-8), while median room traffic per case was 65 entries/exits (IQR 42-76); and per critical step was 17 (IQR 10-65). CONCLUSION: Our data demonstrate that IAEs occur frequently during all phases of the operation at hand. Future study will be required to examine the role of distractions and IAE as well as IAE and their relationship to post-operative clinical outcomes.
