This comprehensive review explores integrated crisis response models that combine the expertise of psychologists, nurses, and paramedics in trauma management. Drawing on international research and practice frameworks, the article examines how these three disciplines can effectively collaborate to address the complex physical, psychological, and social dimensions of traumatic events. The integration of psychological services with traditional emergency medical response represents a significant evolution in trauma care, particularly relevant given global demographic shifts toward aging populations with increasing multimorbidity. Various collaborative models are analyzed, including integrated emergency response systems, collaborative care pathways, and community-based services. Evidence suggests that these approaches can improve patient outcomes, enhance system efficiency, and reduce healthcare costs through appropriate triage, early psychological intervention, and coordinated transitions between care settings. Implementation challenges related to professional boundaries, communication barriers, and organizational constraints are discussed, alongside practical strategies for overcoming these obstacles. The article identifies key competencies for effective collaboration, outlines ethical considerations specific to interprofessional trauma response, and presents recommendations for education, policy development, and future research. By breaking down traditional silos between disciplines, integrated crisis response models offer promising approaches for delivering comprehensive, patient-centered care that addresses both immediate needs and long-term recovery following traumatic events.
