Abstract
Study ObjectiveThe aim of this study was to document the change in ovarian conservation rate after ovarian torsion as a result of continuous quality improvement (CQI) measures, and to determine factors that contribute to this outcome. DesignA retrospective, uncontrolled before-and-after study. SettingAn academic children's hospital. ParticipantsFemale adolescents younger than 18 years with surgically confirmed ovarian torsion from April 1, 1988 to October 15, 2013; excluding cases from 2003 (intervention period). InterventionsImplementation of CQI measures including educational programs, collaborative care pathways, and quality review with the goal of improving ovarian conservation. Main Outcome MeasuresDemographic characteristics, details on presentation, investigations, consultation, surgical intervention, surgical findings, pathology, postoperative course, and follow-up imaging. ResultsOne hundred thirty-nine patients met inclusion criteria (42 pre-CQI cohort and 97 post-CQI cohort). Mean ages were 9.96 and 10.33 years, respectively. Ovarian conservation rates were 47.6% compared with 85.6%, respectively (P < .001). The following factors differed between cohorts: fever (P = .003), ultrasound completed (P = .001), time from first health care provider visit to imaging (P = .025), time from specialist consultation to surgery (P = .002), surgical start time within 1 hour of booking (P < .001), and gynecologist present in operating room (P < .001). A log-binomial regression model showed that gynecology presence in the operating room (relative risk [RR], 2.043) was associated with untwisting. Increasing time from specialist consultation to surgery (RR, 0.986 per hour) was inversely associated with untwisting. Fever at presentation was also inversely associated with untwisting (RR, 0.666). ConclusionThe implementation of CQI measures was associated with a significant increase in ovarian conservation rate.
