Health service quality in Germany can be shown by the data from the external quality assurance program (BQS) but as these records are limited to the period of in-hospital stay no information about outcome after discharge from hospital can be obtained. Secondary routine administrative data contain information about long-term outcome, such as mortality, subsequent revision and the need for care following surgical treatment due to a hip fracture. Experiences in the use of secondary data dealing with treatment of hip fractures from the BQS are available in our department. ⋯ These routine data clearly show a bias because of poor quality in coding as well as broad interpretation possibilities of some of the ICD-10 codes used. Consequently quality assurance using routine data is less valid than register-based conclusions. Nevertheless medical expertise is necessary to avoid misinterpretation of routine administrative data.

Patients under long-term administration of vitamin K antagonists may require temporary interruption of anticoagulation therapy for invasive procedures or trauma surgery. Due to the long half-life of these substances bridging therapy with anticoagulants having a shorter half-life may become necessary. In this situation the risk of bleeding due to the intervention and the risk of thromboembolism due the underlying disease must be assessed. ⋯ New oral anticoagulants will soon become available for stroke prevention in patients with atrial fibrillation and for treatment of venous thromboembolism. Due to the shorter half-lives these compounds will no longer require bridging anticoagulation. However, the trauma surgeon should be familiar with the dosing regimens for different indications in order to adequately decide about the preoperative cessation and the perioperative pause of these anticoagulants.
