[Patient safety-development and evaluation]

Patient safety (PaSi) is no longer understood as merely the prevention of adverse events, but rather as all activities aimed at ensuring a safe care environment and a culture of patient safety. PaSi is considered one of the most pressing goals in healthcare. Consequently, a large number of stakeholders in joint self-administration in Germany are now working to improve PaSi. The methods used to determine PaSi range from patient surveys and voluntary reports by healthcare providers using critical incident reporting systems (CIRS) to analyses of medical records and routine data, while the search for the prerequisites for safe care makes use of classic quality management methods. Evaluation results from Germany indicate that most PaSi incidents (PSI) remain undetected and that there is still a great need for research to investigate PSI incidences, determinants of PSI, and interventions to prevent PSI as well as to create a PaSi culture.
