a. The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSI) software requires that the pulmonary embolism (PE) or deep vein thrombosis (DVT) be reported as a secondary diagnosis (rather than the principal diagnosis), but unlike the AHRQ PSI software, the secondary diagnosis could be present on admission.� In addition, the interruption of vena cava is not verifiable as following surgery.� Excludes obstetric conditions and admissions in which the interruption of vena cava is the only operating room procedure.
b. Rates are adjusted by age, comorbidities, major diagnostic category (MDC), diagnosis-related group (DRG), and transfers into the hospital.� The AHRQ PSI software was modified to not use the present on admission (POA) indicators (or estimates of the likelihood of POA for secondary diagnosis).
