Comparison of pain assessment instruments in cognitively intact and cognitively impaired nursing home residents.

This study was conducted to determine which pain severity and location instruments were most useful in the nursing home setting. Pain severity and location were assessed monthly for 1 year in 37 participants enrolled in a restorative rehabilitation program. Pain location was determined by the residents' indications on a diagram, a doll, and their body. Pain severity was determined by resident response to verbal, visual analog, faces, and word scales. Cognitively impaired residents had greater difficulty using all instruments. The McGill Word Scale was used most to determine pain severity. Pointing to themselves most frequently determined pain location among residents. New strategies are needed for pain assessment in the elderly, especially the cognitively impaired elderly, and a combination of instruments to assess pain in the latter group may be necessary.
