Background: Hysterectomy, the most common gynecological operation, requires surgeons to counsel women about their operative risks. We aimed to develop and validate multivariable logistic regression models to predict major complications of laparoscopic or abdominal hysterectomy for benign conditions.
Methods: We obtained routinely collected health administrative data from the English National Health Service (NHS) from 2011 to 2018. We defined major complications based on core outcomes for postoperative complications including ureteric, gastrointestinal and vascular injury, and wound complications. We specified 11 predictors a priori. We used internal–external cross-validation to evaluate discrimination and calibration across 7 NHS regions in the development cohort. We validated the final models using data from an additional NHS region.
Results: We found that major complications occurred in 4.4% (3037/68 599) of laparoscopic and 4.9% (6201/125 971) of abdominal hysterectomies. Our mo
The new ChessBase Magazine #205 offers a wealth of ideas and recommendations for your repertoire. The topics of the eleven opening articles in the new issue range from the Benko Gambit (4.cxb5 a6 5.b6 e6), the French Tarrasch (8.0-0 g5!), the Ruy Lopez (5.Qe2) to recipes against the King's Indian (after 6.Be2).
