Abstract
BACKGROUND Anticoagulation requires urgent reversal in cases of life-threatening bleeding or invasive procedures. STUDY DESIGN AND METHODS Network meta-analysis for comparing the safety and efficacy of warfarin reversal strategies including plasma and prothrombin complex concentrates (PCCs). RESULTS Seven studies including 594 subjects using reversal agents plasma, 3-factor-PCC (Uman Complex and Konyne), and 4-factor-PCC (Beriplex/KCentra, Octaplex, and Cofact) met inclusion criteria. Compared with plasma, patients receiving Cofact probably have a higher rate of international normalized ratio (INR) correction (risk difference [RD] 499 more per 1000 patients, 95% confidence interval [CI], 176-761, low certainty[LC]); higher reversal of bleeding (323 more per 1000 patients, 11-344 more, LC); and fewer transfusion requirements (0.96 fewer units, 1.65-0.27 fewer, LC). Patients receiving Beriplex/KCentra probably have a higher rate of INR correction (476 more per 1000 patients, 332-609 more, LC); higher reversal of bleeding (127 more per 1000 patients, 43 fewer to 236 more); and similar transfusion requirements (0.01 fewer units, 0.31 fewer to 0.28 more, high/moderate certainty). Patients receiving Octaplex probably have a higher rate of INR correction (RD 579 more per 1000 patients, 189-825 more, LC). CONCLUSIONS PCCs probably provide an advantage in INR reversal compared to plasma. There was no added risk of adverse events with PCCs.
PICO Summary
Population
Adult patients in need of urgent warfarin reversal due to either bleeding or an imminent invasive procedure (7 studies, n= 594).
Intervention
3 factor PCC (Uman Complex, Konyne), and 4 factor PCC (Beriplex/KCentra, Octaplex, and Cofact).
Comparison
Plasma.
Outcome
Compared with plasma, patients receiving Cofact probably had a higher rate of international normalized ratio (INR) correction, higher reversal of bleeding, and fewer transfusion requirements (low certainty). Patients receiving Beriplex/KCentra probably had a higher rate of INR correction (low certainty), higher reversal of bleeding; and similar transfusion requirements (high/moderate certainty). Patients receiving Octaplex probably had a higher rate of INR correction (low certainty).
