Correlates of Length of Hospital Stay Among Emergency Surgery Patients

This report presents a retrospective analysis of emergency general surgery admissions between 2011 and 2017 to identify factors correlated with the length of hospital stay. The study utilized data from 15,297 patients, examining demographic data, comorbidities, surgical interventions, and outcomes. Non-parametric tests, including Wilcoxon and Kruskal-Wallis tests, were employed to determine significant correlates. The findings revealed that age, admission type (transfer), surgical complications, operative cases, and endoscopic procedures were statistically significant factors influencing the length of hospital stay. The study found no significant difference in the length of hospital stay between patients who died and those who survived. The report concludes that these identified factors can be considered potential correlates of length of hospital stay among emergency general surgery patients, providing valuable insights for healthcare professionals to improve patient care and resource allocation. The study also includes the R code used for the analysis, providing a comprehensive overview of the methodology and results.
