Understanding the impact of a collective leadership intervention on team working and safety culture in healthcare teams: a realist evaluation protocol [version 2; peer review: 2 approved]

Abstract

There is accumulating evidence for the value of collective and shared approaches to leadership across sectors and settings. However, relatively little research has explored collective leadership in healthcare and thus, there is little understanding of what works for healthcare teams, why, how and to what extent. This study describes the approach that will be adopted to the realist evaluation of a collective leadership intervention with four heterogenous healthcare teams in four different settings. A realist evaluation will be conducted. Realist evaluation is a theory-based approach to evaluation. It enables the use of mixed-methods to explore the research question of interest. Development of an initial programme theory (IPT) constitutes the first phase of the approach. This IPT will be informed by interviews with members of teams identified as working collectively, an examination of extant literature using realist synthesis, and will be refined through consultation with an expert panel. A multiple case study design will be adopted to explore the impact of the intervention, including quantitative scales on teamworking, leadership and safety culture, realist interviews with key informants and observations of teams during intervention sessions. Analysis of data will be guided by the IPT to refine the theory and context-mechanism-outcome configurations. Findings from the cases will be compared to identify patterns or demi-regularities and to explore if the intervention operates differently in different contexts. This analysis and synthesis of findings across the teams will inform the development of a middle range theory that will not only add to our understanding of how collective leadership influences teamwork and patient safety, but also provide guidance for future collective leadership interventions. Favourable ethical opinion has been received from the University College Dublin Ethics Committee. Results will be disseminated via publication in peer-review journals, national and international conferences and to stakeholders/interest groups.
