Advanced practice nurse capabilities: A mixed methods systematic review.

Capability is a requirement and a necessity in the performance of advanced practice nurses. Identifying and defining the dimensions of advanced practice nurses' capabilities will lead the way in developing the roles, education, and capability assessments of advanced practice nurses. Identification of advanced practice nurses' capability will facilitate role understanding, visibility, and implementation in health care services. This can improve the quality and accessibility of care and improve the cost-effectiveness of the use of health care professionals.
