Patient safety became paramount in medicine as well as in emergency medicine after it was recognized that preventable, adverse events significantly contributed to morbidity and mortality during hospital stay. The underlying errors cannot usually be explained by medical technical inadequacies only but are more due to difficulties in the transition of theoretical knowledge into tasks under the conditions of clinical reality. Crew Resource Management and Human Factors which determine safety and efficiency of humans in complex situations are suitable to control such sources of error. ⋯ Such course formats are not only capable of creating awareness and improvements in safety culture but also improve technical team performance and emphasize team performance as a clinical competence. A few studies even indicated improvement of patient-centered outcome, such as a reduced rate of adverse events but further studies are required in this respect. In summary, simulator-based team training should be accepted as a suitable strategy to improve patient safety.

Clinical Trial
[Anticoagulation medication for proximal femoral fractures : Prospective validation study of new institutional guidelines.]
Under current guidelines surgical care of hip fractures has to be initiated within 48 h which is a challenge for the management of patients on medical anticoagulation. The aim of this study was to evaluate the in-house standard operation procedure (SOP) concerning these patients. ⋯ Under this SOP anticoagulation has no impact on complication rates after hip fracture. The increased transfusion rates under ASS can be attributed to early blood transfusions. Antagonization of coumarin with vitamin K delays surgery but seems adequate. An analysis of more patients over a longer period of time should be conducted.

Patient safety in hospitals is difficult to define and is not measurable by operational safety parameters as in other fields. So-called adverse events (AE) are a collective of complications, failures, mistakes, errors and violations. Estimations of at least 9.2 % AEs in surgery with 0.1 % fatalities are given worldwide but there are no correlations between objective quantification of AEs and subjective or public perception of safety during the perioperative period. ⋯ In spite of these facts, safety parameters for problems in anesthesia, blood transfusion, in retaining surgical instruments and so-called index events, such as patient and side identification errors are much higher. Patient safety is maintained in hospitals by objective means (surgical). Checklists have been proven to improve safety and critical incidence reporting, training and changing of attitudes could have further advantages but they are difficult to measure.

Comparative Study
[Comparison of MRI and CT for assessment of childhood fractures : Studies on a porcine model.]
The purpose of this study was to evaluate the capacity of MRI to achieve a diagnostic accuracy in pediatric fracture diagnosis comparable to CT. ⋯ MRI has a diagnostic accuracy in fracture diagnosis comparable to CT. Therefore, protocols of traumatology in infancy should be revised.

Clinical Trial Observational Study
[Polytrauma with pelvic fractures and severe thoracic trauma : Does the timing of definitive pelvic fracture stabilization affect the clinical course?]
The aim of this study was to investigate the influence of the surgical timing in patients with pelvic fractures and severe chest trauma on the clinical course, especially on postoperative lung function. ⋯ In this study patients with pelvic fractures and thoracic trauma benefited positively from an earlier definitive pelvic fracture stabilization with respect to a shorter time of ventilation and stay in the intensive care unit due to a lower need for red cell concentrates.
