"A systematic review of the available literature on prehospital nursing stressors and how they affect the work of nurses working in the ambulance service was carried out following the PRISMA methodology. A pre-established search and review protocol minimised the risk of selection and publication bias. This protocol was registered in PROSPERO with code CRD42023446080. First, the PECO question was formulated for an adequate literature review (). For this, the following research question was developed: What factors affect the stress levels of prehospital emergency nurses? Methods: Systematic review in PubMed, WOS, Enfispo, Cochrane, and LILACS databases following the PRISMA methodology (last search 08/Aug/2023). Following the PECO framework, studies on occupational stress factors in ambulance emergency nurses were investigated. Studies in English or Spanish, from 2013 to 2023, and only research articles were admitted, thus excluding reviews, dissertations, and grey literature. Possible bias and level evidence were assessed using critical appraisal tools and GRADE. This protocol was registered in PROSPERO with code CRD42023446080."
