One person was killed, and 29 people were injured. This case report aims to give a detailed description of the response of emergency medical services to evaluate cross-border and inter-authority cooperation as well as adherence to major incident guidelines and established communication pathways.</p><p><strong>Case presentation: </strong>Initial calls indicated several critical patients and numerous school children on the train. Nineteen Danish and German units, including four helicopters, were dispatched to the scene. Access to the site was restricted to a single narrow countryside road, requiring careful organization of staging areas, access/egress routes, and casualty clearing stations. A Joint Incident Command was formed, and patients were triaged, treated, and registered using an electronic prehospital system allowing for continuous coordination with the dispatch center for hospital allocation. Two critically injured patients were transported by helicopter to two trauma centers in Denmark and Germany, and the remaining patients were distributed across three regional hospitals. The response to this incident largely aligned with national guidelines and cross-border cooperation agreements. However, delays in incident management were identified, and responders criticized infrequent training opportunities for major incidents. The rate of unauthorized radio shifts was lower than previously described.</p><p><strong>Conclusions: </strong>This report describes the response to a major incident, characterized by effective inter-authority cooperation and successful cross-border collaboration between Danish and German emergency services. Routine collaboration during everyday responses proved crucial to ensure efficient collaboration during crises. While adherence to major incident protocols was generally high, challenges remained regarding the site organization and timely establishment of command structures. The observed delays may reflect limited experience with major incident management among regular responders, prompting the need for comprehensive incident command training of prehospital physicians. Compared to previous incidents, communication consistency was notably improved, likely due to dedicated training efforts after prior communication failure. The incident underscored the importance of joint inter-authority response concepts and the central coordinating role of the dispatch center. Enhanced training accessibility and continued evaluation of real-life incidents are recommended to further improve preparedness for future incidents.</p>","PeriodicalId":49292,"journal":{"name":"Scandinavian Journal of Trauma Resuscitation & Emergency Medicine","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13555936/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148425700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This narrative review synthesises the available evidence on the mechanisms, health effects, and emergency department management of casualties inflicted by crowd-control weapons.</p><p><strong>Main body: </strong>Emergency department preparedness for civil unrest rests on surge capacity planning across staffing, supplies, space, and systems, with additional demands imposed by chemical decontamination, unpredictable patient volumes, and risks to staff safety. Conducted energy devices cause injury primarily through falls during neuromuscular incapacitation and through probe penetration of sensitive structures; cardiac risk is low but may be amplified by comorbidities and intoxication. Routine cardiac monitoring is not supported for alert, asymptomatic patients after brief exposures. Riot control agents (principally 2-chlorobenzylidene malononitrile [CS], chloroacetophenone [CN], and oleoresin capsicum) activate nociceptive ion channels, producing ocular, respiratory, and dermal injury that is largely self-limiting but can be severe, especially in enclosed spaces or vulnerable populations such as infants, elderly and patients with asthma. Management centres on decontamination and supportive care. Kinetic impact projectiles are responsible for the highest burden of permanent disability, particularly ocular injury; initial presentations may appear deceptively benign, and clinicians must maintain a high index of suspicion for occult internal injury guided by mechanism rather than surface findings.

Linear regression was applied to examine for alignment between trends in urgency level over the years and critically versus non-critically severity in prehospital patients assigned to urgency level A (most urgent, potentially life-threatening) and B (less urgent), respectively.</p><p><strong>Results: </strong>Among 202,746 prehospital patients, the proportion assessed as urgency level A decreased from 62% to 59%, while urgency level B increased from 38% to 41%. While the proportion of patients in acute critical condition was 16% vs. 8% among level of urgency A and B, and stable during the period, the number of patients in acute critical condition increased by 3.6 (95% confidence interval (CI) 0.7-6.6) and 6.1 (95% CI 4.4-7.8) per quarter. Across the total population, patient age increased from 64 to 66 years, and the proportion with severe comorbidity increased from 11% to 14%.</p><p><strong>Conclusion: </strong>From 2017 to 2023, the number of patients assigned with an ambulance through 1-1-2 increased, as did patient age and comorbidity. During the years were similar proportions of acute critical severity, but increasingly more among urgency level B. Thus, the acute severity among prehospital patients has not diminished. The lack of alignment between the level of urgencies and the acuity severity found on scene should be monitored carefully, together with mortality and clinical outcomes.</p>","PeriodicalId":49292,"journal":{"name":"Scandinavian Journal of Trauma Resuscitation & Emergency Medicine","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13508413/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148297158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
