Patient safety and quality care require learning organizations. For organizations to pivot and progress they need a workforce skilled and confident in voicing ideas and errors. Expressing issues related to patient safety and quality improvement can be defined as voice behavior.This scoping review aimed to answer two questions: 1) What is the scope of the study of voice behavior in healthcare? 2) How do new graduates in allied health use their voice? The Joanna Briggs guidelines were used to identify 76 articles that were explored using a descriptive and evaluative approach to map the depth and breadth of this topic and identify research gaps.The review revealed that nursing and medicine feature in voice behavior studies, but few studies focus on allied health. An exploration of the concepts emerging from these studies revealed eight topics: power, risk, tenure, leadership, intervention, self, climate, and strategies.Synthesis of the reviewed studies highlights that we know little about allied health new graduates' voice behavior in healthcare. Exploration of voice behaviors with this group will inform education and workplace settings about ways to grow professionals who are confident and competent in speaking up for patient safety and quality improvement.
