Evaluation of a Newly Implemented Critical Thromboelastography (TEG) Value Callback System: A Single Center Experience

Pdf Summary

This report evaluates the impact of implementing a Critical Thromboelastography (TEG) Value Callback System in a single-center setting to improve patient management and blood product utilization. The study compared trauma and critical care patients before (n=20) and after (n=100) implementation of the callback system, analyzing provider responses and changes in TEG parameters. Findings revealed that following callbacks, appropriate management improved significantly, with 42% providing appropriate management and 42% ordering repeat TEG tests. Results also showed that TEG parameters improved in 90% of cases post-callback compared to 57% in the control group. Providers increasingly administered Tranexamic acid (TXA) post-implementation. The study highlights the efficacy of the TEG callback system in guiding clinical decision-making and improving patient outcomes. Challenges included the need for effective communication protocols and potential variations in critical value definitions. Further research is needed to assess the system's impact on patient outcomes. The study underscores the importance of timely and accurate communication of critical values in patient care, aligning with international quality indicators in laboratory medicine. Additional studies could explore new technologies to enhance critical value notifications and their impact on clinical outcomes in patients with excessive bleeding.
