Objective: Unclear is how robotic-assisted surgery affects perioperative anemia and the need for blood products. Methods: In this case-control study, 15,009 matched patient pairs undergoing urological, visceral, or thoracic surgery were included. Pairwise comparisons between robotic-assisted surgery, laparoscopic surgery, and open surgery were performed with propensity score matching. Results: Robotic-assisted surgery compared to open surgery was associated with a risk reduction of allogeneic red blood cell transfusion by RR: 0.32 (95% CI: 0.27\u20130.37) and a limited reduction of perioperative hemoglobin (perioperative hemoglobin difference of 0.40 g\/dL, 95% CI: 0.31\u20130.49). Robotic-assisted surgery was associated with a shorter length of hospital stay by 4.29 days (95% CI: 3.74\u20134.84). Compared to laparoscopic surgery, robotic-assisted surgery had no significant effect on red blood cell transfusions (RR: 0.94, 95% CI: 0.75\u20131.18), perioperative hemoglobin (0.27 g\/dL, 95% CI: 0.16\u20130.38), or length of hospital stay 0.53 days (95% CI: \u22120.14\u20131.19). Conclusions: Robotic-assisted and laparoscopic procedures are associated with reduced blood transfusions compared to open surgery and, thus the advancement of minimally invasive procedures constitutes an important measure to improve patient outcomes.
