Systematic Root Cause Analysis in Patient Safety

Conclusion

Modern patient safety incident investigation has evolved far beyond traditional root cause analysis toward sophisticated systems-based approaches that emphasize sustainable corrective actions over analytical completeness. The evidence demonstrates that properly implemented frameworks like RCA2 and HFACS integration can achieve significant improvements in patient safety outcomes, but success depends critically on organizational commitment, specialized training, and systematic implementation support.

Healthcare organizations must recognize that identifying root causes provides value only when coupled with robust implementation of strong system-level interventions. The research clearly shows that facilities investing in comprehensive RCA programs with adequate resources and leadership support achieve measurably better patient safety outcomes. The transformation from blame-focused incident response to learning-oriented systematic improvement represents both the greatest challenge and most significant opportunity for healthcare patient safety advancement in the coming decade.
