Root Cause Analysis of ICU Adverse Events in the Veterans Health Administration.

BACKGROUND: ICUs' provision of complex care for critically ill patients results in an environment with a high potential for adverse events. A study was conducted to characterize adverse events in Veterans Health Administration (VHA) ICUs that underwent root cause analysis (RCA) and to identify the root causes and their recommended actions.

METHODS: This retrospective observational study of RCA reports concerned events that occurred in VHA ICUs or as a result of ICU processes from January 1, 2013, through December 31, 2014. The type of event, root causes, and recommended actions were measured.

RESULTS: Some 70 eligible RCAs were identified in 47 of the 120 facilities with an ICU in the VHA system. Delays in care (30.0%) and medication errors (28.6%) were the most common types of events. There were 152 root causes and 277 recommended actions. Root causes often involved rules, policies, and procedure processes (28.3%), equipment/supply issues (15.8%), and knowledge deficits/education (15.1%). Common actions recommended were policy, procedure, and process actions (34.4%) and training/education actions (31.4%). Of the actions implemented, 84.4% had a reported effectiveness of "much better" or "better."

CONCLUSION: ICU adverse events often had several root causes, with protocols and process-of-care issues as root causes regardless of event type. Actions often included standardization of processes and training/education. Several recommendations can be made that may improve patient safety in the ICU, such as standardization of care process, implementation of team training programs, and simulation-based training.
