Each dataset is comprised of two sets of variables: VQI variables and Medicare-derived variables. The VQI variables define patient status at the time of surgery, hospitalization, and one year follow-up, when available. The Medicare variables describe hospitalizations and outpatient procedures that occurred subsequent to the index hospitalization through the analytic end date, Five Medicare-derived outcomes variables were created from the merged data to facilitate evaluation of long term outcomes: 1) death, 2) adverse outcome (such as stroke, aortic rupture or amputation) 3) readmission to the hospital 90 days after discharge from the index procedure 4) repeat procedure/reintervention, and 5) post-procedure surveillance imaging (CT or ultrasound). Payment variables are also derived from Medicare claims for the index procedure and outcomes.
