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

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.

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.

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."

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.
