Abstract

Background & Objectives: Many gastrointestinal surgeries are processed every year. To find the risk factors for delaying of the length of stay after surgery of patients undergoing elective gastrointestinal surgery. Materials & Methods: We performed a retrospective clinical study using data from January 2013 to March 2013 in West China hospital, Sichuan University. We selected the patients undergoing elective gastrointestinal surgery, and according the length of stay after surgery we divided them into two groups. Group A included the patients discharged from hospital in average days (≤ 9 days). The patients in Group B stayed in hospital more than average days (> 9 days). For the continuous variables, we used one-sample t test. For binary categorical variables, we used Chi-square test or fisher’s exact test. For ordinal categorical variables, we used Mann-Whitney u test. And logistic regression was used to identify risk factors for delaying the length of stay after surgery. All potential risk factors were analyzed through univariate logistic regression analysis. Results: Among many potential risk factors, we found that unintended weight loss (OR=2.522, CI, 1.222-5.204, p=0.012), prolonged operative time (P=0.003), urine output (P=0.006), fasting time after surgery (Exp (B) =1.628, CI, 1.412-1.879, P=0.000), and postoperative administration of advanced antibiotics (P=0.004) were risk factors which made patients stay longer in hospital after surgery. Conclusion: Length of stay after surgery is a complex outcome influenced by multiple factors. Weight loss, long operative time, less urine output, postoperative infection and fasting after surgery are risk factors for influencing recovery after surgery. Disclosure of Interest: None declared
