Multi-institution Evaluation of Adherence to Comprehensive Postoperative VTE Chemoprophylaxis.

Objectives: The aims of this study were to: (1) measure the rate of failure to provide defect-free postoperative venous thromboembolism (VTE) chemoprophylaxis, (2) identify reasons for failure to provide defect-free VTE chemoprophylaxis, and (3) examine patient- and hospital-level factors associated with failure.

Summary Background Data: Current VTE quality measures are inadequate. VTE outcome measures are invalidated for interhospital comparison by surveillance bias.
