Restrictive transfusion strategies and antifibrinolytic therapy as part of patient blood management contributed to the recent transfusion practice changes.[5] Therefore, performing a subgroup analysis with year as a covariate would be insightful in future studies.

For example, colectomy patients represented the majority of their general surgery codes, but transfusion rates substantially varied between laparoscopic and open colectomies for partial (4.1% vs. 9.4%) and total resection (15.2% vs. 29.6%) (Table 1).
