Abstract
BACKGROUND: Army medical treatment facilities (MTFs) use a surgery scheduling system that reviews historical OR times to dictate expected procedural time when posting new cases. At a single military institution there was a noted inflation to umbilical hernia repair (UHR) times that was leading to issues with under-utilized operating rooms. METHODS: This is a retrospective review determining what variables correlate with longer UHR operative time. Umbilical, ventral, epigastric, and incisional hernia repairs (both open and laparoscopic) were pulled from the local OR scheduling system at Dwight D. Eisenhower Army Medical Center from January 2013 to June 2018. RESULTS: A total of 442 patients were included in the study with a mean age of 45.74 years and 54.98% male. Patient ASA level (p 0.045), primary vs. mesh repair (p < 0.001), number of hernias repaired (p 0.05), hernia size (p < 0.001), and absence of student nurse anesthetist (SRNA) (p 0.05) all correlated with longer UHR OR times. For the aggregated open hernia repair data, almost all independent variables of interest were statistically significant including age, PGY level, history of DM, case acuity, presence of SRNA, patient ASA level, patient's BMI, hernia defect size, number of hernias, history of prior repair, and history prior abdominal surgery. Multivariate regression analysis was done on the open hernia repair variables with only age and size of hernia being significant. CONCLUSION: This data were used to create a new case request option (open UHR without mesh and open UHR with mesh) to more effectively utilize available OR time.
