The Omaha System is a standardized health care terminology consisting of an assessment component (Problem Classification Scheme), an intervention component (Intervention Scheme), and an outcomes component (Problem Rating Scale for Outcomes). Approximately 11,000 interdisciplinary practitioners, educators, and researchers use Omaha System for structured clinical documentation and analysis of secondary data. Omaha System users from Japan, Estonia, Hong Kong, New Zealand, Wales, Canada, The Netherlands, and the United States have presented at international Omaha System conferences.
The Omaha System 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).The Omaha has the ability to code the majority of the problems, interventions, and targets from the hospital record.
The Omaha system is being mapped to the International Classification of Nursing Practice (ICNP). It is a reliable nursing documentation tool for outcome and quality of care measurement for clients with mental illness. The Omaha System is also a tool that can be used as a strategy to introduce and incorporate evidence-based practice in the undergraduate nursing clinical experience. The Omaha system can be used as a strategy to introduce and incorporate evidence-based practice in the undergraduate nursing clinical experience. Tools that can be utilized in the Omaha system include a comprehensive list of client health problems, nursing interventions, and an outcome rating scale assessing client knowledge, behavior, and health status to standardize nursing care and client outcomes.
The Omaha system originated at the Visiting Nurse Association of Omaha (located in Nebraska) as a collaborative effort between researchers and interdisciplinary practitioners. Practitioners developed the Omaha System as part of four federally funded research projects conducted between 1975 and 1993.The Omaha system was constantly refined in its structure and terms during this period to establish reliability, validity, and usability.
Users include nurses, physicians, occupational therapists, physical therapists, registered dieticians, recreational therapists, speech and language pathologists, and social workers.When multidisciplinary health teams use the Omaha System accurately and consistently, they have an effective basis for documentation, communication, coordination of care, and outcome measurement.
