Combined Proactive Risk Assessment: Unifying Proactive and Reactive Risk Assessment Techniques In Health Care

Abstract

Background: Reactive risk assessments (RRAs) such as incident reporting and root cause analysis (RCA), as well as proactive risk assessments (PRAs) such as failure mode and effects analysis, are generally conducted independently in health care. Literature promotes combining risk assessment techniques. This concept builds on previous methodologies and presents an innovative, scalable, and generalizable risk assessment methodology.

Methods: A Combined Proactive Risk Assessment (CPRA) technique entails combining incident reports (RRAs), combining proactive risk assessments (PRAs), and merging components of PRA and RRA. Using specific keywords, this technique aligns patient safety reporting data with process steps and failure modes to assess risk within any of the process steps. This technique was tested by using PRAs from several Veterans Health Administration (VHA) facilities and national patient safety data from the VHA National Center for Patient Safety's database. Reported events and RCAs related to the outpatient blood draw process were used for this illustration. Repeatability was determined by independently applying the technique to two years of data and auditing results.

Results: Aggregating PRAs from multiple facilities identified 220% more failure modes; and integrating incident reports into PRA identified 310% more failure modes than the single facility average. Overlaying safety reports onto a comprehensive process flow diagram revealed that 85.8% of events occurred in three of seven process steps. Accuracy of this technique was generally above 85%.

Conclusion: This technique is promising for identifying vulnerable points in health care processes or to compliment a traditional PRA. Single PRAs are less likely to identify all potential failures or focus on the most hazardous process steps. This technique may aid in assessing key health care processes at an enterprise level.
