Point-of-care-based protocol with first-line therapy with coagulation factor concentrates is associated with decrease allogenic blood transfusion and costs in cardiovascular surgery: an Italian single-center experience.

BACKGROUND: Transfusion in patients having cardiac surgery has been associated with increased morbidity, mortality, and costs. This analysis assessed the impact of a rotational thromboelastometry (ROTEM®)- and functional platelet assessment (Multiplate®)-based protocol for bleeding management on perioperative outcomes and costs in patients undergoing cardiac surgery. METHODS: This retrospective analysis of the records of all patients who underwent cardiac surgery at the Hesperia Hospital, Modena, Italy, from December 2012 to December 2013 compared outcomes and costs of bleeding management for the two 6-month periods before/after introduction of the ROTEM- and Multiplate-based protocol. Descriptive and correlation analysis were performed as appropriate. Propensity score matching and its correlation analysis were performed. RESULTS: Data from 768 consecutive patients (mean age ~69 years, ~66% male) were included; 50.7% and 49.3% of patients had surgery before and after protocol introduction, respectively. Significantly fewer patients required transfusions of packed red blood cells after the protocol introduction over the 24 hours postsurgery (100 vs. 197 patients; P<0.001) and during ICU stay (134 vs. 221 patients; P<0.001). A significantly greater proportion of patients treated after protocol introduction received prothrombin complex concentrate (31 vs. 16; P<0.05) and fibrinogen concentrate (36 vs. 13; P<0.001). A significantly greater proportion of patients treated after protocol introduction had an ICU stay duration <48 hours (81.5% vs. 71.5%; P<0.001). ROTEM-based bleeding management was associated with a saving of €128,676.23 for the 379 patients undergoing surgery post-protocol introduction (€339.52 per patient). CONCLUSIONS: ROTEM-guided bleeding management in patients undergoing cardiac surgery was cost-effective and associated with an increase of administration of coagulation factor concentrates and a decrease of ICU length of stay.
