Reoccurring barriers and facilitators to sepsis recognition and management were commonly identified across the TDF domains of Knowledge, Skills, Environmental Context and Resources, and Social Influences, including competency deficit (with facilitators including support from colleagues), workload or staffing, and equipment or resource availability.</p><p><strong>Conclusion and relevance: </strong>ICU nursing sepsis recognition and management is impacted by numerous individual, environmental, and organizational factors. Recommendations include enhanced competency development or support, utilization of structured reinforcement measures (involving the interdisciplinary team and imploring the use of integrative technologies), and addressing equipment/resource-related gaps. Future research and improvement initiatives should use a theory-informed approach to overcome the pervasive, complex challenges impeding timely sepsis recognition and management.</p>","PeriodicalId":93957,"journal":{"name":"Critical care explorations","volume":"7 1","pages":"e1200"},"PeriodicalIF":0.0,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11732647/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142973730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
