Initiation and Assessment of Timekeeping Roles During In-Hospital Cardiac Arrests to Track Rhythm Checks and Epinephrine Dosing.

OBJECTIVES

Compliance to advanced cardiac life support algorithm is low and associated with worse outcomes from in-hospital cardiac arrests. This study aims to improve algorithm compliance by delegation of two separate code team members for timing rhythm check and epinephrine administration in accordance to the advanced cardiac life support algorithm.

DESIGN

Prospective intervention with historical controls.

SETTING

Single academic medical center.

PATIENTS

Patients who suffered in-hospital cardiac arrest during study period were considered for inclusion. Patients in which the advanced cardiac life support algorithm or new timekeeper roles were not used were excluded.

INTERVENTIONS

Two existing code team members were delegated to time epinephrine and rhythm checks.

MEASUREMENTS AND MAIN RESULTS

Primary endpoint was deviations from the 2-minute rhythm check or 3- to 5-minute epinephrine administration. Each deviation outside allotted time intervals was counted as one deviation. However, instances in which multiple intervals passed were counted as multiple deviations. Algorithm adherence was analyzed before and after intervention. Secondary endpoints included return of spontaneous circulation rate, time until first dose of epinephrine, and anonymous survey data. Thirteen pre intervention in-hospital cardiac arrests were compared with 13 in-hospital cardiac arrests post. Prior to intervention, the median deviation per in-hospital cardiac arrest was 5 (interquartile range, 3-7) versus 1 post (interquartile range 0-1; = 0.0003). The median time until first dose of epinephrine was administered pre intervention was 5 minutes (interquartile range, 0-4) versus post intervention median of 0 (interquartile range, 0-0; = 0.02). Pre-intervention return of spontaneous circulation rate was 46.1% versus 69.2% post. Surveys demonstrated advanced cardiac life support providers felt time keeping roles made it easier to track epinephrine administration and rhythm checks and improved team communication.

CONCLUSIONS

Two separate timekeeper roles during in-hospital cardiac arrests improved algorithm compliance, code team function, and was favored by code team members. Timekeeper roles may be associated with improved rates of return of spontaneous circulation and less time until the first dose of epinephrine was administered. This study is limited by small sample size and single-center design.
