Abstract

Long-term anticoagulation is used worldwide to prevent or treat thrombotic events. Anticoagulant therapy using vitamin K antagonists (VKAs) is well established; however, anticoagulants carry an increased risk of potentially life-threatening bleeding. In cases of bleeding or need for surgery, patients require careful management, balancing the need for rapid anticoagulant reversal with risk of thromboembolic events. Prothrombin complex concentrates (PCCs) replenish clotting factors and reverse VKA-associated coagulopathy. Two forms of PCC, 3-factor (3F-PCC) and 4-factor (4F-PCC), are available. Using PRISMA methodology, we systematically reviewed whether 4F-PCC is superior to 3F-PCC for the reversal of VKA-associated coagulopathy. Of the 392 articles identified, 48 full texts were reviewed, with 11 articles identified using criteria based on the PICOS format. Data were captured from 1,155 patients: 3F-PCC, n = 651; 4F-PCC, n = 504. ROBINS-I was used to assess bias. Nine studies showed international normalized ratio (INR) normalization to a predefined goal, ranging from ≤1.5 to ≤1.3, following PCC treatment. Meta-analysis of the data showed that 4F-PCC was favorable compared with 3F-PCC overall (odds ratio [OR]: 3.50; 95% confidence interval [CI]: 1.88–6.52, p < 0.0001) and for patients with a goal INR of ≤1.5 or ≤1.3 (OR: 3.45; 95% CI: 1.42–8.39, p = 0.006; OR: 3.25; 95% CI: 1.30–8.13, p = 0.01, respectively). However, heterogeneity was substantial (I 2 = 62%, I 2 = 70%, I 2 = 64%). Neither a significant difference in mortality (OR: 0.72; 95% CI: 0.42–1.24, p = 0.23) nor in thromboembolisms was reported. These data suggest that 4F-PCC is better suited than 3F-PCC for the treatment of patients with VKA-associated coagulopathy, but further work is required for a definitive recommendation.
