MSS07: OPERATIVE TIME TRACKING FOR DDEAMC UMBILICAL HERNIA PATIENTS
Elisabeth O Coffin, MD; Dana Poloni, MD, Captain US Army; Pamela Burgess, MD; Dwight D Eisenhower Army Medical Center
Army MTFs use a surgery scheduling system that reviews historical OR times to dictate expected length of times when posting new cases. At Dwight D. Eisenhower Army Medical Center there was a noted inflation to umbilical hernia repair (UHR) times that was leading to issues with scheduling UHRs. This is a retrospective review determining what variables correlate with longer UHR operative time. Age (p <0.0001), BMI (p <0.0001), ASA (p <0.0001), defect size (p <0.0001), and number of hernias (p 0.002) were positively correlated with OR time, indicating that as they increase, OR time increases. PGY level was also found to influence OR time (PGY1 with longer OR times than PGY4, p <0.0001). Emergent procedures (p 0.0002), procedures with SRNA (p 0.0251), mesh repair (p <0.0001), having a history of prior UHR (p <0.0001), and having a history of prior abdominal surgery (p <0.0001) were also found to have increased OR times. Multivariate regression analysis was done between these variables with no significant inter-variable influence. This data was used to create a new case request option (open UHR without mesh and open UHR with mesh) to more effectively utilize available OR time.
