Abstract
BACKGROUND AND AIMS: Recent guidelines recognize the limitations of standard coagulation tests in predicting bleeding and guiding pre-procedural blood component prophylaxis in cirrhosis. It is unclear whether these recommendations are reflected in clinical practice. We performed a nationwide survey to investigate pre-procedural transfusion practices and opinions of key health care stakeholders involved in managing cirrhosis. METHODS: We designed a 36-item multiple-choice questionnaire to investigate the international normalized ratio and platelet cutoffs utilized to guide pre-procedural transfusion of fresh frozen plasma and platelets in patients with cirrhosis undergoing a range of low and high-risk invasive procedures. Eighty medical colleagues from all mainland States involved in managing patients with cirrhosis were invited by email to participate. RESULTS: Overall, 48 specialists across Australia completed the questionnaire: 21 gastroenterologists, 22 radiologists, and 5 hepatobiliary surgeons. 50% of respondents reported that their main workplace did not have written guidelines relating to pre-procedural blood component prophylaxis in patients with cirrhosis. There was marked variation in routine prophylactic transfusion practices across institutions for the different procedures and international normalized ratio and platelet cutoffs. This variation was present both within and between specialty groups and held for both low and high-risk procedures. For scenarios where the platelet count was ≤ 50 × 109/L, 61% of respondents stated that prophylactic platelet transfusions would be given before low-risk and 62% before high-risk procedures at their center. For scenarios where the international normalized ratio was ≥2, 46% of respondents stated that prophylactic fresh frozen plasma would be routinely given before low-risk procedures and 74% before high-risk procedures. CONCLUSION: Our survey reveals significant heterogeneity of pre-procedural prophylactic transfusion practices in patients with cirrhosis and discrepancies between guidelines and clinical practice.
