Prevalence and impact of arthritis among nursing home residents.

OBJECTIVE To determine the prevalence, characteristics, and impact of arthritis in the US nursing home population. METHODS A national cross sectional sample of US nursing homes (8138 sampled residents in 1406 nursing homes) from the 1997 National Nursing Home Survey provided demographic and functional characteristics for residents with primary arthritis, any arthritis, or no arthritis diagnosis at admission. RESULTS Of the estimated 1.6 million current nursing home residents in 1997, only 43,000 (3%) had a primary and 300,000 (19%) had any arthritis diagnosis at admission. People with a primary or any arthritis diagnosis received physical/occupational therapy, used wheelchairs and walking aids, and needed assistance with walking and transferring more often than those with no arthritis diagnosis. CONCLUSIONS These national estimates suggest that arthritis is underreported in nursing home residents. Because arthritis contributes to an increased physical burden on staff and decreased functional capability of residents, both staff and residents can benefit from better diagnosis, intervention, and education.
