Peer review is a major component of a professional practice and shared governance model in which professional staff nurses are given responsibility for practice and patient outcomes. Careful planning is necessary for the development of a peer-review program. Components include definition of roles, responsibilities, and performance standards, as well as the development of an evaluation tool and process. Peer review affords nurses many opportunities for growth and development and allows them to develop communication, evaluation, and presentation skills. The concept of peer review may expand to meet the needs of changing health-care delivery models.
