- W4240914102 abstract "Abstract Background: Hospital length of stay (LOS) remains an important metric in analysis of surgical services. Modifiable factors to reduce LOS are few in number and the ability to practically take action is limited. Surgical scheduling of elective cases remains an important task in optimizing workflow and may impact the post-surgical LOS. Methods: Retrospective data from a single tertiary care academic institution were analyzed for quality improvement of elective adult surgical cases performed from 2017 through 2019. Variables included primary procedure, age, diabetes status, ASA class, and surgical start time. Analysis of the median LOS following surgery was performed using Mann-Whitney tests and Cox hazards model. Matched-cohort analysis of mean total hospitalization costs was performed using the Student’s T-test. Results: 9258 patients were analyzed across five surgical service lines, of which 777 patients had surgical start time after 3PM. The median LOS for the after 3PM group was 1 day longer than the before 3PM start time cohort (3.0 vs 2.1, p<0.001). Service line analysis revealed increased LOS for Orthopedics and Neurosurgery (3.0 vs 1.9, p<0.001; 3.0 vs 2.0, p<0.05). Multivariate-analysis confirmed that start time before 3PM predicted shorter LOS (HR=1.214, 1.126-1.309; p<0.001). Case-matched cost analysis for frequently performed orthopedic and neurosurgical cases with an after 3PM start time failed to demonstrate a significant difference in total hospital charges. Conclusion: Optimization of surgical services scheduling to increase the proportion of elective surgical cases started before 3PM has the potential to decrease post-surgical LOS for adult patients undergoing Orthopedic or Neurosurgical procedures." @default.
