An intranet-based system for quality assurance in surgery.

Quality assurance in surgery relies on precise medical records about surgical procedures and outcomes. Data quality is crucial for statistical evaluation; missing values cannot be avoided but must be minimized. The quality assurance system must be accessible from many locations within the clinic; given the complex and heterogeneous computing infrastructure this is a technological challenge. Intranet-technology--the application of internet-tools in local networks--can help to solve the technical problems. We designed, implemented and evaluated a generic Intranet-based quality assurance system in surgery. The basic concept is multi-purpose data entry with predefined textblocks, i.e. the same data is used for clinical reports as well as scientific evaluations. Our first instance were reports on laparoscopic cholecystectomies consisting of 41 Items and 132 textelements. Because of the good clinical acceptance of the system it will be expanded to other surgical procedures.
