Defining competencies for nurse anaesthetists: A Delphi study.

The lack of regulation of the competencies of nurse anaesthetists leads to great variability in training and practice. The results can help in their standardization in Spain and in other countries lacking regulation. Our approach can also help policymakers and hospital administrators in health systems that are undergoing the process of regulation. The regulation of the competencies of nurse anaesthetists will allow them to contribute their expertise to the health-illness continuum, increasing safety and improving the quality of care.
