Key result
Concordance between administrative and clinical data sources for postoperative complications was poor to moderate (e.g., sepsis K=0.054-0.16, DVT K=0.51-0.60), driven by differing definitions.

May limit reliability of administrative data for surgical outcome monitoring; leaves open need for validated hybrid sources in research.
Observational
There is considerable discordance between administrative and clinical data sources in measuring postoperative complications, primarily due to differing definitions.
Koch et al. (2012) conducted an observational in Postoperative complications. Administrative data (AHRQ PSIs) vs. Clinical registries (NSQIP, CVIR) was evaluated on Concordance of postoperative complications (hemorrhage, respiratory failure, DVT, sepsis) between data sources. Concordance between administrative and clinical data sources for postoperative complications was poor to moderate (e.g., sepsis K=0.054-0.16, DVT K=0.51-0.60), driven by differing definitions.
