Importance of Estimated Blood Loss in Resource Utilization and Complications of Hysterectomy for Benign Indications.

Objective: To identify the variation in estimated blood loss at the time of hysterectomy for benign indications and to analyze how blood loss is associated with measures of resource utilization and complications.

Methods: We conducted a retrospective cohort study and analyzed hysterectomy for benign indications at hospitals in the Michigan Surgical Quality Collaborative between January 1, 2013, and May 30, 2015. A sensitivity analysis was performed to identify how estimated blood loss was associated with measures of utilization (transfusion, readmission, reoperation, and length of stay) and postoperative complications.
