Entwicklung der operativen Uroonkologie in Deutschland – vergleichende Analysen aus populationsbasierten Daten

Although urologic cancer represents a relevant health economic burden with about 100,000 new cases per year, hardly any knowledge exists about the structure and development of the corresponding uro-oncological interventions at the more than 400 urological surgical hospitals in Germany. Thus, we identified all cases of 5 major tumor surgery procedures in Germany from the DRG (diagnosis-related group) database of the Federal Statistical Office (prostatectomy, cystectomy, renal tumor surgery, retroperitoneal lymphadenectomy, penis surgery) from 2006–2013 (or 2016) by database query and investigated the influences of technical innovations, as well as guideline changes on the developments of case numbers. In addition, we analyzed the correlations between annual case numbers and perioperative outcomes. The results showed a clear correlation between case volume (and thus expertise) of a hospital and an improved perioperative outcome. Nevertheless, there is hardly any tendency towards centralization in these uro-oncological interventions. The development in the number of cases seems to depend more on the effect of advertising by means of technical innovations or the regional relation of the patients to a certain clinic. In the past, centrally controlled attempts to introduce minimum case numbers or voluntary certification of centers had little influence on the distribution of case numbers.
