“…In the present study, the crude incidence proportion of in-hospital bleeding events for the index admission ranged from 1.0% (95% CI = 0.6–1.3%) among patients undergoing prostate surgery to 3.0% (95% CI = 2.3–3.6%) among patients undergoing low anterior resection; these estimates are generally comparable to those in the existing literature. The rate of bleeding complicating a procedure has been reported to be 2.5% for mastectomy, 23 0.5–2.6% for prostatectomy, 24–26 1.3–1.9% for thoracic surgery, 27 0.4% to 6.4% for hysterectomy, 28–30 and 10.9% for low anterior resection 31 (for low anterior resection, the comparatively higher rate is likely explained by a broader definition of bleeding, which included not only hemorrhage and hematoma complicating a procedure but also seroma and acute post-hemorrhagic anemia). None of the aforementioned studies were based in UK, however, underscoring the unique contribution the present study adds to the literature.…”
