Product-specific Incidence Rates of Perioperative Transfusion-associated Circulatory Overload Overall and by Index Year

	Overall No./Total (%)	2004 No./Total (%)	2011 No./Total (%)
Erythrocytes only	90/3,322 (2.7)	74/1,853 (4.0)	16/1,469 (1.1)
FFP only	11/93 (11.8)	7/34 (20.6)	4/59 (6.8)
Platelets only	2/89 (2.2)	0/32 (0.0)	2/57 (3.5)
Mixed products	73/564 (12.9)	38/243 (15.6)	35/321 (10.9)

Multivariable logistic regression analyses demonstrated that the frequency of transfusion-associated circulatory overload was related to both blood product group (P < 0.001) and calendar year (P < 0.001). Two patients were excluded from this secondary analysis (one received only fresh whole blood and one received only cryoprecipitate; neither experienced transfusion-associated circulatory overload).

FFP = fresh-frozen plasma.
