[Current developments in the German Perinatal Survey. Modular analysis tools operating on a database platform].

The introduction of the modified data set for quality assurance in obstetrics (formerly perinatal survey) in Lower Saxony and Bavaria as early as 1999 saw the urgent requirement for a corresponding new statistical analysis of the revised data. The general outline of a new data reporting concept was originally presented by the Bavarian Commission for Perinatology and Neonatology at the Munich Perinatal Conference in November 1997. These ideas are germinal to content and layout of the new quality report for obstetrics currently in its nationwide harmonisation phase coordinated by the federal office for quality assurance in hospital care. A flexible and modular database oriented analysis tool developed in Bavaria is now in its second year of successful operation. The functionalities of this system are described in detail.
