Who will be readmitted? Evaluation of the laparoscopic hysterectomy readmission score in a gynecologic oncology population undergoing robotic-assisted hysterectomy

Objectives. The laparoscopic hysterectomy readmission score (LHRS) was created to identify patients for whom same day discharge (SDD) after minimally invasive hysterectomy (MIH) may not be advisable and includes diabetes, chronic obstructive pulmonary disease, disseminated cancer, chronic steroid use, bleeding disorder, length of surgery, and any postoperative complication prior to discharge. We evaluated the performance of the score at predicting readmission in a gynecologic oncology population, and additionally sought to determine if any factors known prior to surgery could replace those that are not known until the time of surgery (operative time and postoperative complication). Methods. This was a single-institution retrospective cohort study of women undergoing robotic hysterectomy by a gynecologic oncologist in 2018. Associations between pre-operative, operative and post-operative factors and 30-day readmission, SDD and postoperative complications were assessed using logistic regression. Results. The 30-day readmission rate among the 423 women in the cohort was 45% and 1.9% in those undergoing SDD. Readmission rates by LHRS were: score 1 (4.9%), score 2 (7.8%), score 3 (13.6%), score 4 (16.7%). Patients with a LHRS of >= 3 had higher odds of readmission compared to those with a lower score (OR 4.20, p = 0.02). Infectious morbidity accounted for the majority of postoperative complications, emergency room visits and readmissions. We did not identify preoperative factors to replace the intra- and post-operative factors used in the score. Conclusions. The readmission rate following MIH is low, and a LHRS of >= 3 is associated with increased risk of readmission. Our findings support the applicability of the LHRS to a gynecologic oncology population; addressing risk factors for postoperative infection or doser follow up for patients with a LHRS >= 3 could reduce postoperative readmissions.
