Objectives: To determine the likelihood of same-day discharge (SDD) among patients with obesity undergoing laparoscopic gynaecologic oncology surgery and identify predictors of SDD.
Methods: We conducted a retrospective cohort study of gynaecologic oncology patients who underwent laparoscopic procedures between January 2012 and June 2016. Patients were categorized as non-obese, obese class I/II and obese class III (BMI <30, 30-39.9, and ≥40 kg/m2, respectively). We used univariate and multivariable logistic regression to identify variables associated with SDD.
Results: Of 496 patients, 288 were non-obese, 161 were obese class I/II, and 47 were obese class III. Overall, 182 patients (36.7%) were discharged same day; 44% of these were non-obese, 30% class I/II and 15% class III. On multivariable analysis, we found negative predictors for SDD to be obesity (OR 0.54; P = 0.03), procedure length (OR 0.51; P < 0.01), and higher American Society of Anesthesiologists (ASA) score (OR 0.63; P < 0.01), while we found being pre-booked for SDD (OR 9.16; P <0.01) was a positive predictor of SDD. Among all patients with obesity, only procedure length (OR 0.47; P < 0.01) and being pre-booked for SDD (OR 9.67; P < 0.01) were associated with SDD when we controlled for BMI, ASA score, intraoperative complications, type of surgery, and surgical start time. Patients discharged same day were less likely to present to the emergency department within 30 days of surgery (OR 0.48; P = 0.01).
Conclusion: Among the study cohort and after controlling for potential confounders, women with class I, II, and III obesity had a much lower likelihood of SDD than non-obese women. The only significant predictors of SDD among patients with obesity were duration of procedure and pre-booking for SDD. Further study is needed to identify strategies to improve SDD rates among patients with obesity.
