Influencing factors of nurses’ disaster preparedness: a systematic review and meta-analysis

Abstract

Background: The growing frequency and severity of natural disasters threaten global health and socioeconomic stability. As frontline responders, nurses play a critical role in disaster preparedness and response. Taking into account the lack of research on the various influence factors associated with nurses’ disaster preparedness, This research aimed to systematically summarize the influencing factors and quantitative data, and conduct a meta-analysis. It provides a reference for related nursing research and the formulation of management policies. Design: Systematic review and meta-analysis. Data sources: Systematic search of PubMed, Web of Science, EMbase, Cochrane Library,EBSCO,China Biomedical Literature Database (Sinomed), China Knowledge Network Journal Database (CNKI), Wanfang Database,and Chinese Science and Technology Journal Database (Weipu) from the time of database construction to February 2025. Methods: The researcher completed literature selection,quality assessment,data extraction, and analysis of all included literature.Mean scores on the Nurse Disaster Preparedness Rating Scale and their effect sizes were summarised using Meta-analysis in the Stata 18.0 software package.Finally,subgroup analyses were performed to explore sources of heterogeneity between studies. Results: A total of 2455 documents were retrieved,47 papers were included,and 15 influences were extracted;Meta-analysis revealed that the main influences on nurses' disaster preparedness included whether they had participated in a disaster relief event,whether they had participated in disaster relief training,age,and gender,education background,professional title,hospital grade,years of experience,and department of work. Conclusion: The study showed that nurses' disaster preparedness is influenced by a combination of factors.Hospital administrators can develop appropriate interventions based on different influencing factors to enhance nurses' disaster readiness and reserve disaster relief nursing talent.
