[Outcome parameters for clinical studies: change of paradigm?]. / Klinische Studien, Outcome-Parameter. Ein Paradigma-Wechsel?

In the context of comparative clinical studies in surgery and in orthopedic surgery different therapies, techniques, or implants have been compared. Recent scientific publications mainly mention clinical outcome measurements such as fracture union, ROM, infection rate, as well as patient-related criteria such as pain or return to work (RTW) in order to evaluate the success of the treatment. It becomes obvious that more often than not the term "return to work" is not clearly defined. It is not mentioned who measures which criteria at which point in time, nor are part-time occupation, job change, or training on a new job part of the considerations.
