Nurse–physician collaboration, autonomy, and decision-making ability among intensive care unit nurses in Tehran, Iran: A cross-sectional study

Among the intensive care unit nurses within this sample, higher perceived professional autonomy and enhanced interprofessional collaboration were independently correlated with improved self-reported clinical decision-making capabilities. Given the cross-sectional nature of the study, causality cannot be established. Longitudinal research employing objective performance metrics is necessary to examine causal relationships and to guide organizational strategies that foster both autonomy and collaborative practice.
