Europe’s and the world’s security has worsened in the last couple years, and with that the possibility of war became a reality. Because of that Sweden’s civil defence system is going through a revival for the first time since the end of the Cold War. The civil defence system is tasked with making sure that societally important functions keep operating even in disasters and war. One of these is the healthcare system, which includes care in hospitals, at primary care facilities, and ambulances. The Swedish Emergency Medical Services are included in the civil defence system and thus their organisations need to work on contingency planning and preparedness efforts. In order to get an understanding of where this process is at the moment, a case study is conducted by interviewing personnel working within the EMS in Sweden. Themes are identified to showcase the level of preparedness and competency the Swedish EMS has now. The study is grounded in previous research and has identified significant topics like the low level of disaster preparedness among nurses, the long- and short-term consequences of working in dangerous conditions, and that training is possibly the most important when it comes to preparations. The interview materials are analysed by abductive thematic analysis and the results show that the Swedish EMS is not prepared to deal with war, and more resources and training is needed in order to achieve a desired level of preparedness.
