    Episode 5: The Numbers Game: CPR Quality & Data-Driven Medicine


    Nicole Kupchik, MN, RN, interviews Dr. Dana Edelson who works with the University of Chicago as a hospitalist and is the founder and CEO of Quant HC.

    Dr. Edelson discusses the importance of patient-driven and data-driven medicine and her work regarding CPR quality – including how her team addressed the “pause problem” and lowered their median CPR pause to less than 2 seconds.

    The Longest Pause - Clinical Summary

    Brouwer T, Walker R, Chapman F, Koster, R. Association Between Chest Compression Interruptions and Clinical Outcomes of Ventricular Fibrillation Out-of-Hospital Cardiac Arrest. Circulation. 2015;132:1030-1037.

    Notably, this study finds that:

    • In 36% of patients, the longest pause was a non-shock chest compression pause. Survival was significantly lower in this group than in the patients whose longest pause was during defibrillation.
    • Fewer long pauses may be more harmful than multiple short pauses, even if overall chest compression fraction is similar.
