235 Late Start Times Do Not Disproportionately Prolong Operating Times in Major Head and Neck Reconstruction

Abstract

Abstract Introduction Operating start time delays are deemed as having a detrimental effect on theatre efficiency, subsequent delays, costs, and potentially outcomes. This study assessed the significance of delayed operating start times on major head and neck reconstruction cases and whether later starts led to disproportionately later finishes. Focus was placed on free osteocutaneous fibula flap reconstruction due to long operating times, difficult anaesthesia, frequently overrun and the perception of increased morning efficiency. Method Single centre identification of 26 patients using coding informatics that were diagnosed with an intra oral malignancy or osteoradionecrosis requiring reconstruction with a free osteocutaneous fibula flap. Data was manually retrieved between 2015 to 2020 from electronic patient records and statistical analysis was completed using Microsoft Excel. Results Total number of patients collated was 27, however 1 was excluded due to insufficient electronic logging of patient data. The total mean age was 64.8 (40-79), 50% were male (13) and 50% were female (13). The mean start time was 9:57, end time was 18:52 and duration was 10:50 (4:46 to 13:42). For surgery start times before 10:00 a.m. the mean start time was 9:31, end time was 20:16 and duration was 10:46 (8:30 to 22:56). For surgery start times after 10:00 a.m. the mean start time was 10:22, end time was 19:25 and duration was 10:54 (10:01 to 00:51). Conclusions Delayed operating start times have minimal significance on theatre efficiency and don’t disproportionally prolong operating times in major head and neck reconstruction cases.
