Real\u2010time risk stratification for VTE is important to guide measures for thromboprophylaxis.

The primary outcome was 90\u2010day postoperative VTE (including deep venous thrombosis and pulmonary embolism [PE]). We used the 2001\u20132010 dataset to create a new VTE predictive model using multivariable logistic regression. We then compared the discrimination of the Caprini score (adapted for claims data), the Elixhauser comorbidity score, and the new predictive model using the 2011\u20132015 dataset.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Our sample included 15\u2009479 patients (12\u2009005 pancreas and 3474 liver surgery). Median age was 74 years (interquartile range: 69\u201378) and 7619 were female (49%). The overall incidence of 90\u2010day VTE was 10.0% (90\u2010day PE: 4.5%). The new VTE model included age, race, history of VTE, cancer stage, preoperative chemotherapy, and Elixhauser score.
