A safety information system (SIS) has been used at all Hirslanden hospitals since 2008, offering employees in all occupational groups the chance to file anonymous reports about mistakes that might have led to harmful incidents, and thus establishing a constructive error culture.

Reported cases are recorded and categorised in the Critical Incident Reporting System (CIRS), before being analysed and processed by an interdisciplinary committee.

Particularly complex CIRS cases that also have a high learning potential are analysed in more detail. A cause­-and­-effect diagram (also known as the Ishikawa method) is used here for systematic incident analysis. The goal is also to learn as much as possible from potential incidents.
