title: Hysterectomy in Germany: a DRG-based nationwide analysis, 2005-2006.
abstract: BACKGROUND
  Hysterectomy is among the more common surgical procedures in gynecology. The aim of this study was to calculate population-wide rates of hysterectomy across Germany and to obtain information on the different modalities of hysterectomy currently performed in German hospitals. This was done on the basis of nationwide DRG statistics (DRG = diagnosis-related groups) covering the years 2005-2006.
  
  
  METHODS
  We analyzed the nationwide DRG statistics for 2005 and 2006, in which we found 305 015 hysterectomies. Based on these data we calculated hysterectomy rates for the female population. We determined the indications for each hysterectomy with an algorithm based on the ICD-10 codes, and we categorized the operations on the basis of their OPS codes (OPS = Operationen- und Prozedurenschlüssel [Classification of Operations and Procedures]).
  
  
  RESULTS
  The overall rate of hysterectomy in Germany was 362 per 100 000 person-years. 55% of hysterectomies for benign diseases of the female genital tract were performed transvaginally. Bilateral ovariectomy was performed concomitantly in 23% of all hysterectomies, while 4% of all hysterectomies were subtotal. Hysterectomy rates varied considerably across federal states: the rate for benign disease was lowest in Hamburg (213.8 per 100 000 women per year) and highest in Mecklenburg-West Pomerania (361.9 per 100 000 women per year).
  
  
  CONCLUSIONS
  Hysterectomy rates vary markedly from one region to another. Moreover, even though recent studies have shown that bilateral ovariectomy is harmful to women under 50 who undergo hysterectomy for benign disease, it is still performed in 4% of all hysterectomies for benign indications in Germany.
