We read with interest the article by Buchberg et al1 on venous thromboembolic events in patients undergoing colorectal surgery. Venous thromboembolic events are not only a significant cause of morbidity and mortality in surgical patients but also a commonly monitored and publicly reported quality-of-care measure.2 Therefore, it is vital that we effectively and reliably determine whether differential rates of venous thromboembolism and other postoperative complications can be used to inform surgical decision making.
