Table 2 Association between allogeneic blood transfusion and type of infection during hospitalisation for coronary artery bypass graft surgery

From: Hospital variation in transfusion and infection after cardiac surgery: a cohort study

Outcome: Number (%) with infection during hospitalisation Odds ratio for allogeneic transfusion* (95% CI) P value
Genitourinary system infection 1,567 (6.3%) 1.27 (1.03, 1.55) 0.023
Respiratory tract infection 1,247 (5.0%) 2.45 (1.88, 3.21) < 0.001
Septicaemia or sepsis 506 (2.0%) 3.65 (2.22, 6.00) < 0.001
Infection of skin or subcutaneous tissue 392 (1.6%) 2.27 (1.48, 3.48) < 0.001
Postoperative infection (site undefined) 382 (1.5%) 2.02 (1.31, 3.11) 0.002
Infection with C. difficile 127 (0.5%) 3.16 (1.36, 7.35) 0.008
Circulatory system infection 130 (0.5%) 1.65 (0.92, 2.95) 0.093
Digestive tract infection 118 (0.5%) 2.11 (1.01, 4.44) 0.048
  1. Note: some patients had more than one type of infection.
  2. *Adjusted for propensity score, surgeon volume and hospital volume.
