Welcome to the Omaha System Web site!

The Omaha System is a research-based, comprehensive practice and documentation standardized taxonomy or classification designed to document client care from admission to discharge. The hierarchy and terms of the Omaha System are summarized in the Overview, and include an assessment component (Problem Classification Scheme), an intervention component (Intervention Scheme), and an outcomes component (Problem Rating Scale for Outcomes).

Users: Current users represent the continuum of care; their location, size, organization, type of services, and type of employees are increasingly diverse. More than 9000 multidisciplinary practitioners, educators, and researchers use Omaha System point-of-care software in the United States and other countries. The number of users will be updated during 2013.  The number and type of computer software vendors who offer automated Omaha System clinical information systems continue to grow rapidly.
