This document defines and outlines utilization management (UM). UM is the process of assessing healthcare services to determine if care is medically necessary, appropriate, efficient, and meets quality standards. The purposes of UM include ensuring effective and efficient use of resources, continually assessing access and quality of care, and complying with regulations. Goals are promoting high quality, cost-effective care and making decisions based on medical necessity. Types of UM include prospective review before care, concurrent review during care, and retrospective review after care. The structure involves UM committees and councils. Nurses' duties in UM include concurrent review, precertification, monitoring staff, discharge planning, and maintaining accurate records.
