Fixed- versus variable-dose prothrombin complex concentrate protocol for vitamin K antagonist reversal.

Fixed-dose prothrombin complex concentrates (PCCs) for the reversal of vitamin K antagonists may decrease the incidence of thromboembolic events, treatment costs, and treatment delays. However, the ideal fixed dose is unknown, with some studies showing inadequate reversal with suboptimal dosing or in patients with a higher international normalized ratio (INR) or weight. This indicates a need for a modified fixed-dose strategy that considers weight and INR.

Comparison of Rates of Nephrotoxicity Associated with Vancomycin in Combination with Piperacillin-Tazobactam Administered as an Extended versus Standard Infusion.

Study Objective: Despite recent reports of relatively high rates (16-37%) of acute kidney injury (AKI) in patients receiving the combination of intravenous piperacillin-tazobactam (PTZ) and vancomycin, data are limited evaluating the impact of PTZ infusion strategy on the occurrence of nephrotoxicity. The objective of this study was to compare the rates of nephrotoxicity in patients receiving vancomycin in combination with PTZ administered as an extended infusion (EI) versus a standard infusion (SI).

Design: Single-center, retrospective, matched-cohort study.
