The increasing number of working-age adults with a long-term disability has created a need for case management focused on quality-of-life issues as well as functionality. An adaptation of the Quality Health Outcomes Model was used to explore relationships between case manager types and services and characteristics of adults with a disability. Outcome measures included social participation, health maintenance behaviors, and economic productivity. Secondary data analysis of the 1994 National Health Interview Survey Disability Supplement provided a purposive sample of 371 working-age adults with a disability (AWDs). Problems with instrumental activities of daily living and activities of daily living were reported by 74.7% of participants, with activity limitations a main predictor of outcome achievement. Although family members or friends were chosen by 78% of the sample to coordinate their medical care, case manager type demonstrated no influence on the outcome measures. Rehabilitation nurses should use their knowing of person to develop, implement, and evaluate interventions and systems focused on the ability of AWDs to achieve quality-of-life outcomes.
