The authors define moral climate in the context of health care as the implicit and explicit values that drive health-care delivery and shape the workplaces in which care is delivered. Over the past six years, their research has focused on describing the moral climates of nurses' workplaces and improving them. In this article, the authors argue that nurses in direct care delivery roles have the insights, expertise and interpersonal skills required to create a much safer moral climate for practice. To make this happen, nurses require opportunities for self-reflection and for true collaboration with their colleagues in management and administration and other health-care disciplines.
