The authors studied a tool called PULSE designed to help teachers run better debriefing sessions after simulation exercises in nursing education. They compared regular debriefings with ones using PULSE and found that PULSE improved the quality and organization of discussions and helped students stay more engaged. Teachers also noticed the tool encouraged more interactive conversations. The authors suggest PULSE could be helpful but say that bigger studies are needed to confirm these early results and improve the tool.

Abstract
Debriefing is central to effective simulation-based education. However, effective debriefing is challenged by high instructor workloads and limited engagement of observing students. A real-time annotation tool to support debriefing, called PULSE, was co-designed with nursing educators. A field study comparing three standard simulation debriefings with three debriefings using PULSE was conducted as a preliminary evaluation. Outcomes were assessed using the Debriefing Assessment for Simulation in Healthcare (DASH) student survey and a follow-up instructor interview. PULSE significantly improved overall DASH scores (t(4) = 4.03, p = 0.027, Cohen's d = 2.05). Survey findings suggested improvements in debriefing organization and depth of reflection. Interview data indicated that the student-generated annotations enhanced engagement and stimulated more interactive discussions. PULSE shows promise as a support tool for debriefing, particularly by facilitating reflection of observing students. However, larger and more diverse studies are needed to confirm effectiveness and refine the system for broader implementation.
