The psychiatric clinical specialist's impact on psychiatric emergency services.

Psychiatric emergency services have evolved into more comprehensive programs during the past two decades. With this evolution other disciplines have gained access to the services and integrated their expertise and philosophy into the daily care of patients. Nursing has been an integral part of this process and contributed its perspective in nursing care. This paper outlines the development of psychiatric emergency services with a special emphasis on the contribution of nursing specialists who have developed their role within the psychiatric emergency service. What has been unique about the nursing contribution is the attention to individualizing patient care and modifying treatment approaches to meet the patients' needs and interests in psychiatric treatment. Additionally, nursing has complemented the physician's role by developing expertise in assessment that is both psychologically and biologically oriented. Nursing's future contribution to psychiatric emergency services should address mechanisms for tracking patients who enter the psychiatric emergency service system with an emphasis on linkage with other programs or resolution of the crisis episode.
