Health care costs in the United States and, more specifically, in the Military Health Services System MHSS continue to rise at an unacceptable rate. In an effort to curb rising costs, military treatment facilities MTFs are implementing utilization management UM as part of their managed care programs. UM can be defined as a deliberate action taken by purchasers to manage health care costs and influence the hospitals andor physicians decision-making process in order to increase the efficiency and appropriateness with which health care services are provided. At Keller Army Community Hospital KACH, the UM nurse consultant is expected to be a key component of the UM program. This project develops the role and functions of the UM nurse consultant at KACH. By defining the most appropriate role and functions of the nurse consultant, KACH will move towards ensuring that appropriate, cost effective and high quality care is being rendered to all patients seeking treatment at KACH.
