[German S3 practice guidelines on prevention of venous thromboembolism--New and established evidence]

Any recommendations of the previous practice guidelines on prevention of venous thromboembolism have been put to the test and have been revised in the latest edition in case new evidence had become available. Recommendations which have proven themselves in clinical practice have remained unchanged such as algorithms for risk assessment, however there are now updates on the recommendations of novel oral anticoagulants for prevention of venous thromboembolism, on the use of mechanical prophylaxis, on heparin-induced thrombocytopenia and on prophylaxis in outpatients after surgical procedures.
