Identifying influential individuals on intensive care units: using cluster analysis to explore culture

AimThe objective of this paper is to identify attribute patterns of influential individuals in intensive care units using unsupervised cluster analysis. BackgroundDespite the acknowledgement that culture of an organisation is critical to improving patient safety, specific methods to shift culture have not been explicitly identified. MethodsA social network analysis survey was conducted and an unsupervised cluster analysis was used. ResultsA total of 100 surveys were gathered. Unsupervised cluster analysis was used to group individuals with similar dimensions highlighting three general genres of influencers: well-rounded, knowledge and relational. ConclusionsCulture is created locally by individual influencers. Cluster analysis is an effective way to identify common characteristics among members of an intensive care unit team that are noted as highly influential by their peers. To change culture, identifying and then integrating the influencers in intervention development and dissemination may create more sustainable and effective culture change. Additional studies are ongoing to test the effectiveness of utilising these influencers to disseminate patient safety interventions. Implications for nursing managementThis study offers an approach that can be helpful in both identifying and understanding influential team members and may be an important aspect of developing methods to change organisational culture.
