Commentary: Digital cross-sectoral training with dynamic patient and situation simulation in the context of mass casualty incidents—insights from the research projects D2PuLs and D2PuLs PRO

A commentary on Konrad R, Pfadenhauer T, Eckenweber L, Banahovschi A, Braun C, Reuter T, Popp S, Engelen C, Baierl L, Soy M and Bauer C (2026) Digital cross-sectoral training with dynamic patient and situation simulation in the context of mass casualty incidents-insights from the research projects D2PuLs and D2PuLs PRO. Front. Disaster Emerg. Med. 4:1756349. doi: 10.3389/femer.2026.1756349. Konrad et al. describe a modular digital simulation environment that combines dynamic patient physiology, configurable clinical and prehospital scenarios, hybrid use with manikins, and data-supported debriefing for mass-casualty incident training (1). This is a valuable advance because it makes deterioration, competing demands, and resource allocation more visible than static patient cards. The evidence is nevertheless preliminary: the reported field tests primarily addressed feasibility, usability, technical implementation, organizational process, and self-assessed learning rather than observed clinical performance or patient-safety outcomes (1). A nursing-focused extension should therefore build on the platform's demonstrated feasibility while avoiding claims of established effectiveness.The clinical field trial included 13 participants, of whom seven had nursing qualifications: six with specialist training in emergency, anesthesia, or intensive care and one with general nursing preparation (1). However, evaluation results were presented for the clinical group as a whole. This aggregation limits interpretation because nursing and medical participants may have different responsibilities, learning needs, interface risks, and performance expectations. Future D2PuLs evaluations should define professionspecific learning objectives before each scenario and report outcomes by role, while preserving interprofessional team measures. examine what happened, why it happened, and which system conditions shaped performance. Evidence-77 based debriefing standards emphasize planned reflection and a safe learning environment (8,9). 78In conclusion, D2PuLs offers a promising and adaptable foundation, but its nursing value will depend 79 on making nursing roles, objectives, and outcomes explicit. The appropriate next claim is not that patient 80 safety has already improved, but that platform provides preliminary feasibility evidence and a testable 81 opportunity to strengthen nursing and interprofessional performance across the mass-casualty care 82 pathway. 83
