The German statutory accident insurance organization is supporting a research project to evaluate the outcome quality of medical treatment procedures associated with this insurance, with the aim of setting examples of particular kinds of injuries and injury patterns as the basis for a results-oriented evaluation of medical treatment measures. A first step was to select injury patterns that should be included. A two-step Delphi survey was carried out. A total number of 160 respondents could choose from a list of injury patterns, both suitable and unsuitable, to include. They could also suggest and evaluate further injury patterns. In both surveys, the number of participants was 60%. Injury patterns rated as particularly suitable included fractures of the distal radius (75.9%), ankle joint fractures (61.1%), and anterior cruciate ligament rupture (43.3%), whereas vertebral body fractures (9.3%), hand injuries (3.7%), and pelvic fractures (1.9%) were rated as less suitable. The Delphi survey proved to be a suitable instrument for the selection of injury patterns.
