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).
Omaha System Overview
Consists of three relational, reliable, and valid components designed to be used together:
Problem Classification Scheme (client assessment)
Intervention Scheme (care plans and services)
Problem Rating Scale for Outcomes (client change/evaluation)
Has terms that are arranged in a hierarchy (i.e. from general to specific), and are intended to be easily understood by health care professionals and the general public. It provides a structure to document client needs and strengths, describe multidisciplinary practitioner interventions, and measure client outcomes in a simple and user-friendly, yet comprehensive, manner.
Problem Classification Scheme
The Problem Classification Scheme provides a structure, terms, and system of cues and clues for a standardized assessment of individuals, families, and communities. It helps practitioners collect, sort, document, classify, analyze, retrieve, and communicate health-related needs and strengths. It is a comprehensive, orderly, non-exhaustive, mutually exclusive taxonomy or hierarchy. The Problem Classification Scheme consists of four levels of abstraction. Four domains appear at the first or most general level. Forty-two client problems or areas of concern are at the second level; by definition, problems are neutral, not negative. The third level consists of two sets of problem modifiers: health promotion, potential, and actual as well as individual, family, and community. Clusters of signs and symptoms that describe actual problems are at the fourth or most specific level. Using the Problem Classification Scheme with the Intervention Scheme and Problem Rating Scale for Outcomes creates a comprehensive problem-solving model for practice, education, and research.
Environmental Domain: Material resources and physical surroundings both inside and outside the living area, neighborhood, and broader community.
Psychosocial Domain: Patterns of behavior, emotion, communication, relationships, and development.
Physiological Domain: Functions and processes that maintain life.
Health-related Behaviors Domain: Patterns of activity that maintain or promote wellness, promote recovery, and decrease the risk of disease.
