Role Delineation of the Code Blue Team: A Quasi-Experimental Study During COVID-19
Introduction:
The purpose of this study was to assess if implementing a code role delineation intervention in an emergency department would improve the times to defibrillation and medication administration and improve the nurse perception of teamwork.
Methods:
A quantitative quasi-experimental study used a retrospective chart review to gather data. A pre- and post-test measured nurse perception of teamwork in a code using the Mayo High Performance Teamwork Scale (MHPTS) after a code role delineation intervention using a paired samples t-test. Pearson r correlations were used to determine relationships between nurse participant (N = 30) demographics and results of the MHPTS scores.
Results:
A significant increase in teamwork was noted in 5 of the 16 items on the MHPTS regarding improved communication and identified roles in a code: the team leader assures maintenance of an appropriate balance between command authority and team member participation (t = -5.607, P < .001), team members demonstrated a clear understanding of roles (t = -5.415, P < .001), team members repeat back instructions and clarifications to indicate that they heard them correctly (t = -2.400, P = .029), all members of the team are appropriately involved and participate in the activity (t = -2.236, P = .041), and conflicts among team members are addressed without a loss of situation awareness (t = -2.704, P = .016). There was significance between total pre- and post-test scores (t = -3.938, P = .001).
Discussion:
Implementation of code role delineation identifiers is an effective method of improving teamwork in a code in an emergency department setting.
