Abstract 248: Initiation and Assessment of Timekeeping Roles During In-Hospital Cardiac Arrests to Track Rhythm Checks and Epinephrine Dosing

Abstract

Introduction: Compliance to ACLS cardiac arrest algorithm is low and associated with worse outcomes from in-hospital cardiac arrests (IHCA). Reasons for non-compliance include reduced communication due to chaotic nature of IHCAs and difficulty timing epinephrine administration and rhythm check intervals. Hypothesis: Delegating two separate code team members for rhythm and epinephrine timing will increase adherence to ACLS algorithm during IHCAs. Methods: This is a pre-post interventional study of IHCAs at a single academic medical center. Two stopwatches were placed on all code carts and two new timekeeping roles were created. Education was provided to staff regarding the alteration of existing code team member roles for the use of stopwatches. Algorithm adherence was analyzed pre and post implementation of timekeeper roles. Deviation from the 2-minute rhythm check or 3-5-minute epinephrine administration was counted as one deviation. Anonymous surveys were delivered to evaluate providers perceived benefits of timekeeper roles for IHCAs. Results: Data from 13 pre intervention IHCAs were compared to 12 IHCAs post intervention. The initial rhythm was PEA/asystole in 69% pre-intervention vs 83% post intervention. Prior to implementation 82 deviations vs. 11 deviations post implementation occurred (p=0.006). The mean time until first dose of epinephrine was administered pre intervention was 2.3 ± 3.3 minutes vs 0.4 ±1 minute post. Pre-implementation ROSC rate was 53.8% vs. 66.7% post intervention. Surveys were delivered to 100% of code team members post intervention, with a 79% response rate. Surveys demonstrate providers felt time keeping roles made it easier to track epinephrine administration and rhythm checks. On a Likert scale, 78% of providers “strongly agree” that the use of timekeeping roles and devices improved code team communication. Conclusion: Two separate timekeeper roles during IHCAs improved algorithm compliance, code team function and communication, and was favored by code team members. Timekeeper roles may be associated with improved rates of ROSC and less time until the first dose of epinephrine is administered. This study is limited by its small sample size, single center and requires validation.
