The Effectiveness of Root Cause Analysis: What Does the Literature Tell Us?

Overall, the limited literature on RCA effectiveness provides anecdotal evidence that RCA improves safety. At the same time, it highlights the numerous theoretical problems with the analytical framework. Formal studies at the system level and cost-benefit analysis are needed to determine the effectiveness of RCA. Structured publication of case studies will support shared knowledge and will provide benchmarks for improvement. Enrichment of the RCA literature body will enable reproducibility of improvement work, optimization of analysis, and validation of the framework itself.
