Transfusion-associated circulatory overload: A survey among Dutch intensive care fellows.

Objectives Transfusion-associated circulatory overload (TACO) is a severe pulmonary transfusion reaction and leading cause of transfusion-related morbidity and mortality in Europe. TACO is of particular importance in critically ill patients, since they often receive blood transfusions and have multiple risk factors for TACO. This study investigates transfusion practices in patients at risk of developing TACO, and furthermore knowledge concerning risk factors, diagnoses and treatment strategies among Dutch intensive care unit (ICU) fellows. Material and methods An unannounced paper-based survey was conducted among Dutch ICU fellows during an educational conference. The survey consisted of 16 multiple and open choice questions. Results Of all 65 Dutch ICU fellows 56.8% completed the survey; of respondents 88.9% identified the correct constellation of symptoms for TACO. In total, 29.7% of the respondents are aware they are obligated to report TACO cases to the blood bank. Major risk factors for TACO that respondents identified were reduced left ventricular function, infusion volume and infusion rate. In a non-emergency setting, 45.9% of fellows start red blood cell transfusion with 2 units or more. Transfusion rates exceeded national guidelines in 15.4% of fictitious cases. TACO is treated with furosemide by 94.5% of the fellows, however goals of the therapy varied greatly. Conclusion Dutch ICU fellows are knowledgeable of TACO symptoms, risk factors and treatment, however knowledge on reporting and transfusion practice in the setting of at risk patients for TACO should be improved.
