The standardization of procedural flow and medical documentation increasingly allows further possibilities. The best-known example of process standardization is the centralized treatment of complex clinical pictures, while patient-reported outcome measurements (PROMs) enable standardized documentation. Using the example of prostate cancer, existing literature on the topic of quality optimization in medicine is discussed. The following key points are addressed: (1) Increasing use of standardized PROMs for outcome documentation. (2) The transfer of complex clinical pictures to dedicated specialized centers has been shown to increase the quality of patient care as long as standardized PROMs are used. (3) Healthcare policymakers benefit from the use of PROMs and increasingly pursue a "value-based healthcare" approach.
