Two established frameworks for debriefing medical teams after simulated cardiac arrests provide comparable experiences for physicians, according to a randomized cross-over simulation study published in Advances in Simulation. The research found no statistically significant difference in overall debriefing quality between the DISCERN and Post-Code Pause (PCP) methods, suggesting that either approach can be implemented in clinical practice without compromising perceived debriefing effectiveness. This finding addresses a gap in the literature where the optimal framework for post-resuscitation debriefing (PRD) had remained undefined despite recommendations from major medical bodies such as the European Resuscitation Council and the American Heart Association.
The study, conducted at the University Hospitals Leuven in Belgium, aimed to explore whether two debriefing frameworks with different inherent intentions are associated with differences in the perceived debriefing experience. DISCERN, which stands for Debriefing In Situ Conversation after Emergent Resuscitation Now, focuses primarily on performance review and team learning. In contrast, PCP emphasizes emotional reflection and addressing the psychological needs of staff following a cardiac arrest. Although both frameworks incorporate elements of clinical learning and psychological support, their structural differences prompted the researchers to investigate how these distinct emphases influence the subjective experience of the team members involved.
To facilitate a direct comparison, the researchers embedded a cross-over design within a larger randomized controlled trial investigating the impact of an extracorporeal cardiopulmonary resuscitation protocol. Forty medical doctors participated in the study, all of whom were either pursuing or had completed a specialization in emergency medicine, anesthesiology, or internal medicine. Participants were required to have completed an Advanced Life Support course within the five years preceding the study. The sample size was determined by practical constraints and feasibility within the parent study, resulting in a convenience sample rather than a power-based calculation.
The simulation scenarios were designed to closely replicate pre-hospital cardiac arrest situations, incorporating spatial and organizational challenges such as evacuation constraints. The scenarios also included emotionally charged components, such as distressed bystanders and cases with significant psychosocial context. In 75% of the scenarios, the patient remained in cardiac arrest, while in 25%, return of spontaneous circulation was achieved. These outcomes were predefined in the scripts and occurred independently of the participants’ clinical performance. Each simulation lasted precisely 15 minutes and was conducted in a dedicated skills lab that mimicked real-world pre-hospital conditions, including suboptimal working space.
During the simulations, the resuscitation team consisted of one physician, one nurse-paramedic, and two ambulance operators. The physician role was consistently performed by the study participant, reflecting their routine clinical function. The other team members were played by medical students who performed standardized roles and followed role-specific scripts. This standardization ensured consistency across simulations but inevitably reduced the authenticity of team dynamics, a limitation acknowledged by the researchers. The debriefings were led by six study investigators, all physicians with experience in simulation and advanced life support, who followed scripted guides specific to the assigned framework to reduce variability in delivery.
Each participant experienced two debriefings using the DISCERN framework and two using the PCP framework, with the order randomized. The primary outcome of the study was the total score on the Debriefing Experience Scale (DES), a 20-item instrument designed to evaluate participants’ experience of debriefing following simulation training. The DES covers four core domains: reflection on thoughts and feelings, learning and making connections, facilitator skill, and facilitator guidance. A total of 158 DES questionnaires were analyzed, with each participant contributing four observations corresponding to their four simulations.
The results showed that the mean total DES scores were nearly identical for both frameworks. The mean score for PCP was 4.15, with a 95% confidence interval of 4.02 to 4.28, while the mean score for DISCERN was 4.16, with a 95% confidence interval of 4.02 to 4.29. The p-value for the comparison was 0.93, indicating no statistically significant difference between the two methods. These scores indicate a favorable debriefing experience for both frameworks, as participants generally agreed that the debriefing helped them analyze their thoughts, connect their learning, and reflect on their actions during the simulation.
At the item level, the majority of DES items showed no statistically significant differences between the frameworks. However, one item regarding the physical comfort of the debriefing environment yielded a significant difference. Participants rated the physical comfort significantly higher under the DISCERN framework, with a mean score of 4.44, compared to 4.13 under PCP (p < 0.0001). Specifically, 47.4% of evaluations under DISCERN selected “completely agree” for this item, compared to 23.8% under PCP. The researchers noted that while the debriefings occurred in the same physical space, the difference might reflect broader aspects of the learning climate, such as psychological safety, or be influenced by the 10-second silent pause characteristic of the PCP framework.
The use of simulation as a methodological platform allowed for a controlled approximation of the clinical experience of team-based resuscitation. This approach enabled multiple debriefings to be conducted within a relatively short time frame while ensuring a high degree of standardization across scenarios and debriefings. However, the researchers emphasized that simulation cannot fully replicate the complexity, unpredictability, and emotional intensity of authentic clinical encounters. In real-life resuscitations, healthcare professionals face genuine patient outcomes and exposure to human suffering, which may elicit stronger emotional responses. Consequently, the dynamics of post-event debriefings in clinical practice may differ from those observed in this simulation-based study.
Several limitations were identified in the study. No a priori sample size calculation was performed, although post-hoc analysis suggested sufficient power to detect a difference of 0.2 points in the total DES score. The unequal distribution of debriefings across the six facilitators, combined with the fact that their allocation did not account for the framework type, represents a potential source of bias. Additionally, the DES has not been specifically validated for physicians, and its focus on simulation training may underrepresent nuanced emotional reflection relevant to real clinical debriefings. Only physicians were enrolled as formal participants, limiting the generalizability of the findings to other team members such as paramedics or ambulance operators.
The findings align with previous research, including a systematic review by Phillips et al., which found that although several clinical debriefing tools exist, the available evidence does not clearly support one framework as superior. A prior mixed-methods study by Kam et al. compared DISCERN and PCP in in situ debriefings following pediatric critical events and found both frameworks effective, with PCP preferred for emotional support. The discrepancy in findings may be attributed to the differing clinical contexts; real pediatric critical events are highly emotionally charged, potentially allowing the strengths of PCP in addressing emotional needs to become more evident than in the simulation-based setting of the current study.
The study suggests that the selection of a debriefing approach may be guided by the intended focus of specific debriefing sessions rather than a universal preference for one framework over the other. Both DISCERN and PCP yielded equally favorable debriefing experiences, reinforcing their suitability as structured approaches in daily practice. The results provide practical reassurance to educators and clinical leaders that either framework can be safely integrated without compromising the quality of the debriefing. Future research should include more professionally diverse participant samples and assess long-term debriefing outcomes to better understand the broader impact of these frameworks on learning and psychological well-being.
The DISCERN framework, developed as a standardized tool for post-resuscitation debriefings, utilizes the plus-delta method to structure verbal discussions. In this approach, participants first identify positive aspects of their performance, referred to as the “plus,” before discussing areas for improvement, known as the “delta.” This structured sequence promotes balanced reflection and targeted feedback, serving as a foundation for the development of other debriefing frameworks. Conversely, the Post-Code Pause process begins with a brief moment of silence, typically lasting 10 to 15 seconds, intended to honor the patient and recognize the team’s efforts. This initial pause facilitates immediate emotional processing, a mechanism that prior research by Copeland et al. reported reduced lingering emotional responses within 24 hours of the event. Both frameworks were applied to identical simulation scenarios to enable a direct comparison of their distinct structural emphases on clinical learning versus emotional reflection.
The Debriefing Experience Scale used to measure participant responses was originally developed through literature review, expert input, and psychometric testing. It consists of 20 items rated on a Likert scale, where one indicates strong disagreement and five indicates strong agreement. The instrument encompasses four core domains: reflection on thoughts and feelings, learning and making connections, facilitator skill, and facilitator guidance. Although the scale was initially validated in nursing students and subsequently in various healthcare student groups, it has not been specifically validated for physicians. The researchers considered it suitable for this study because it evaluates fundamental, profession-independent dimensions of reflection and perceived facilitator support that represent core components of debriefing processes across different healthcare professions.
Statistical analysis accounted for the repeated measures design by using linear models with generalized estimating equations. This method handled the potential correlation between the four observations contributed by each participant. The models corrected for the participants’ specialty, which included emergency medicine, anesthesiology, or internal medicine, as well as the specific scenario used. Because the debriefing framework was a within-subject factor, there was no imbalance in the distribution of scenarios or specialties between the two tools. Adding these terms to the model aimed to decrease residual variance and increase the precision of the estimate for the difference between the frameworks, rather than to remove bias. All analyses were performed using SAS software, version 9.4, ensuring a rigorous approach to comparing the mean scores between the DISCERN and PCP methods.
