Welcome to the Omaha System Web site!

The Omaha System is a research-based, comprehensive practice and documentation standardized taxonomy designed to describe client care. The Omaha System is summarized in the Overview, and includes an assessment component (Problem Classification Scheme), a care plan/services component (Intervention Scheme), and an evaluation component (Problem Rating Scale for Outcomes).

Calling all beginners and experts! The Omaha System International Conference is a unique opportunity to learn, network, and expand your use of the Omaha System. Join us April 20-22; see the Conferences page and PDF Flier for speaker list and agenda.

Users: Users represent the continuum of care and are increasingly diverse. More than 22,000 multidisciplinary clinicians use Omaha System point-of-care software in the United States and other countries. The number and type of computer software vendors who offer Omaha System clinical information systems continue to grow.

Recognition/Electronic Health Records: The American Nurses Association recognized the Omaha System as a standardized terminology to support nursing practice in 1992. In 2014, Minnesota became the first state to recommend ANA-recognized point-of-care terminologies be used in all Electronic Health Records (EHRs). The evidence underlying this decision was a survey that showed that the Omaha System was used in 96.5% of Minnesota counties. The Omaha System became a member of the Alliance for Nursing Informatics in 2009. It meets US Department of Health and Human Services interoperability standards for EHRs, having passed the Healthcare Information Technology Standards Panel (HITSP) Tier 2 criteria for Use Cases in 2007. Additionally, it is integrated into the National Library of Medicine’s Metathesaurus; CINAHL; ABC Codes; NIDSEC; Logical Observation Identifiers, Names, and Codes (LOINC®); and SNOMED CT®. It is registered (recognized) by Health Level Seven (HL7®), and is congruent with the reference terminology model for the International Organization for Standardization (ISO).
