The purpose of this literature review is to find out how incidents related to unintended consequences in caring processes are reported by patients or their families, and the status of patient reporting systems globally. The focus of the study is on patient self-reporting systems, and patient centrism. For that purpose, this scoping review examines studies that summarize the current position of patient self-reporting in health care. Scopus, PubMed including MEDLINE, and Cochrane retrievals, and hand search revealed in 50 articles for further analysis. The results showed that patient-reported incidents are still ifrequently researched. Patient reporting systems were implemented to some extent, but not worldwide in spite of the existence of several report systems. More research is obviously needed, especially within organizations where patient self-reporting systems are in use.
