A manual is presented to help incorporate team development into training programs for nurse practitioners, physician assistants, and primary care physicians. It is also directed to practitioners who wish to improve teamwork and is designed to improve the utilization of the nurse practitioners and physician assistants. A group of one or more mid-level practitioners and one or more physicians is referred to as a team. Team development includes improving the coordination of team activities, decision-making, utilization of team members' skills, problem solving, and conflict negotiation. The development of a team depends on many factors, including the commitment of the organization or institution to the concept and the commitment and the personalities of the individuals on the team. The process of team development includes knowledge of team concepts and development methods, small group process, problem-solving experience, and joint clinical practice. Five modules are presented: health care team development (concepts, issues, and influences); roles and barriers to team development; team building skills; team practice organization; and health care team maintenance. Each module contains exercises and readings that help team members examine their attitudes about areas of team practice. Bibliographies identify longer resource documents, and the exercises focus on skills to improve team practice and patient care. (SW)
