DVT, Deep venous thrombosis; NC, not captured; NSQIP, National Surgical Quality Improvement Program; PE, pulmonary embolism; PSI, Patient Safety Indicator; VQI, Vascular Quality Initiative.
P values reflect proportion testing against the PSI system. P values derived by comparing NSQIP with VQI were insignificant with the exception of “any complication” and “renal” (both P < .001). Boldface P values represent statistical significance. Spearman ρ values reflect rank correlation testing against the PSI system.
