Pain in Nursing Home Residents: An Exploration of Prevalence, Staff Perspectives, and Practical Aspects of Measurement

Abstract
To help rectify the underdiagnosis of chronic pain in frail nursing home residents by developing a new feasible pain self-report instrument, the structured pain interview; to use this new tool to estimate pain prevalence and staff's knowledge of residents' pain in two nursing homes; and to compare the performance differences of the structured pain interview and the commonly used 0-10 scale. Cross-sectional survey. One 120-bed VA-affiliated and one 125-bed university-affiliated, community-based nursing home in Durham, North Carolina. One hundred fifty-eight chronic care nursing home residents without aphasia, acute illness, persistent vegetative status, or severe hearing impairment and 31 nursing home nurses. Pain prevalence according to resident self-report and nurse report; stability of response to the structured pain interview and 0-10 scale over 1 month; agreement between residents and nurses on the structured pain interview and 0-10 scale. Fifty-eight percent of the VA and 45% of the community nursing home residents reported pain. Forty-two percent at the VA and 20% at the community home were unable to respond to the 0-10 scale, compared with 7.5% and 14% using the structured pain interview. Stability of response to the structured pain interview at 1 month was 0.56 at the VA (nurse-resident agreement 0.38) and 0.72 in the community (nurse-resident agreement 0.07), which was very comparable to the 0-10 scale. We have developed a highly feasible tool for examining pain prevalence in nursing homes. This tool uncovered considerable miscommunication regarding pain between residents and staff. Improvement in pain communication between nursing home residents and staff is needed, so that more effective pain treatment programs can be developed for this vulnerable population.
