Increasing use of anticoagulants in Germany and its impact on hospitalization rates for genitourinary bleeding

AbstractThe aim of the study was to compare nationwide time trends of prescribed oral anticoagulants (OAC) with the time trend of genitourinary bleedings (GUB) in Germany from 2005 through 2016. The annual numbers of hospitalized patients with GUB coded as “hematuria”, “excessive, frequent and irregular menstruation”, “postmenopausal bleeding” or “abnormal uterine and vaginal bleeding” were extracted from the nationwide hospitalization file by the Federal Bureau of Statistics. Hospitalization rates were age-standardized using the Germa n standard population 2011. Defined daily doses (DDD) of prescribed anticoagulants among outpatients for the same calendar period were extracted from reports of the statutory health insurance drug information system. Based on DDD, drug treatment rates per 100,000 person years (py) were calculated. F rom 2005 to 2016, annual OAC treatment rates per 100,000 py increased by 135.8% (from 901.4 to 2125.9). Until 2011 direct oral anticoagulants (DOAC) represented less than 0.1% of all OAC, but 49.9% in 2016. In the same period age-standardized rates of hospitalizations for hematuria increased continu ously (annual change of 1.03 (95% CI 0.94–1.11) per 100,000 py), that of “postmenopausal” (− 1.93; 95% CI − 2.38 to − 1.49) or “excessive, frequent and irregular menstruation” decreased (− 1.25; 95% CI −1.62 to − 0.87) and that of “abnormal uterine and vaginal haemorrhage” remained almost unchanged. From all case...
