The relationship between organizational culture and implementation of clinical practice guidelines: a narrative review

The context in which critical care providers work has been shown to be associated with adherence to recommendations of clinical practice guidelines (CPGs). Consideration of contextual factors such as organizational culture may therefore be important when implementing guidelines. Organizational culture has been defined simply as "how things are around here" and encompasses leadership, communication, teamwork, conflict resolution, and other domains. This narrative review highlights the results of recent quantitative and qualitative studies, including studies on adherence to nutrition guidelines in the critical care setting, which demonstrate that elements of organizational culture, such as leadership support, interprofessional collaboration, and shared beliefs about the utility of guidelines, influence adherence to guideline recommendations. Outside nutrition therapy, there is emerging evidence that strategies focusing on organizational change (eg, revision of professional roles, interdisciplinary teams, integrated care delivery, computer systems, and continuous quality improvement) can favorably influence professional performance and patient outcomes. Consequently, future interventions aimed at implementing nutrition guidelines should aim to measure and take into account organizational culture, in addition to considering the characteristics of the patient, provider, and guideline. Further high quality, multimethod studies are required to improve our understanding of how culture influences guideline implementation, and which organizational change strategies might be most effective in optimizing nutrition therapy.
