Approach to “best-of-breed” safety classification creation. Data points of interest from multiple sources including the ICPS, MERS-TM, AHRQ Common Formats, and standards from regulatory and accrediting agencies such as the FDA, CAP, and AABB were incorporated to create comprehensive transfusion and laboratory safety classifications. Questions for each indicator utilizing internal terminology were developed, while the data points themselves were mapped to appropriate classes within the ICPS framework in the SRS database schema. For example, patient identification related data are classified under “wrong patient”, which facilitates aggregate reporting for this category.
