[The German Thorax Registry: Implementation of an Established Tool of Perioperative Health Care Research].

The collection of clinical treatment data in registry databases is an important aspect of health services research. It allows for a critical evaluation of the safety, efficacy and cost-effectiveness of clinical treatment concepts in large patient populations. The findings of registry research represent real-world patients and treatment structures as they are not limited by strict inclusion criteria or unrealistic conditions as applied in prospective clinical trials. The implementation of the German Thorax Registry has enabled the collection and analysis of data on the interdisciplinary care (thoracic surgery, anaesthesiology, intensive care, pain management) of patients undergoing thoracic surgery. Under the auspices of the German Society of Anaesthesiology and Intensive Care Medicine and the German Society of Thoracic Surgery, a registry of the Hospital of the University Witten/Herdecke-Cologne, purely surgical at first, was expanded in close cooperation with the University Hospital of Freiburg. After a comprehensive data protection concept was drafted and a test phase completed, the German Thorax Registry was officially launched in January 2016. Most notably, participating hospitals profit from the registry's "benchmarking" services. "Benchmarking", i.e. the comparison of treatment quality between different hospitals, enables participants to identify individual profiles, strengths and weaknesses on a nation-wide level and follow their own progress over the course of several years. An online database for data entry and benchmarking is always accessible (www.thoraxregister.de). In October 2016, the spectrum of participants was expanded to include all hospitals performing at least 50 thoracic operations a year.
