Systematic Root Cause Analysis in Patient Safety

Healthcare’s approach to patient safety incident investigation has fundamentally transformed over the past five years, moving beyond traditional root cause analysis toward comprehensive systems-based methodologies that emphasize sustainable corrective actions. The most significant finding is that traditional RCA approaches fail to prevent incident recurrence in 93% of cases, primarily due to weak interventions and poor implementation rather than analytical deficiencies. Modern frameworks like RCA2 and HFACS integration demonstrate up to 73% improvement in corrective action effectiveness when properly implemented with strong system-level interventions.

This evolution reflects growing recognition that identifying root causes is only valuable when coupled with robust implementation of sustainable solutions. Leading healthcare organizations have shifted from individual blame-focused investigations to systematic approaches that address organizational vulnerabilities, human factors, and environmental conditions. The research reveals that healthcare facilities conducting comprehensive RCA programs experience significantly lower adverse event rates, but success depends critically on organizational commitment, specialized training, and sustained implementation support.
