[Need for innovation in working with adverse events].

Patient safety has been in focus in the Danish health care for the past five years, with a mandatory reporting system for adverse events/incidents at hospitals. The incidents have been analysed with the Root Cause Analysis. This analysis is a relatively simple linear cause effect analysis, however, not suitable for the use in a complex sociotechnic health-care system. There is a need for other methods and approaches, which can reflect this complexity and focus on the future prospective prevention.
