Predictive index for 90-day postoperative outcomes following gynecologic surgery.

Assessment of the potential of LACE+ index scores in patients undergoing gynecologic surgery to predict short-term undesirable outcomes. Retrospective study over a 2-year time period (2016-2018). Coarsened exact matching was used to assess the predictive capacity of the LACE+ index among all gynecologic surgery cases over a 2-year period (2016-2018) at 1 health system (N = 12,225). Study subjects were matched on characteristics not assessed by LACE+, including race and duration of surgery. For comparison of outcomes, LACE+ score was divided into quartiles and otherwise matched populations were compared in reference to LACE+ quartile (Q): Q4 vs Q1, Q4 vs Q2, Q4 vs Q3. A total of 1715 patients were matched for Q1 to Q4, 1951 patients were matched for Q2 to Q4, and 1822 patients were matched for Q3 to Q4. Escalating LACE+ score significantly predicted increased readmission, reoperation, and emergency department (ED) visits from 30 to 90 postoperative days as well as readmission, reoperation, and ED visits from 0 to 90 postoperative days. The results of this study suggest that the LACE+ index is suitable as a prediction model for important patient outcomes in a gynecologic surgery population.
