Pain Management in Nursing Home Residents: Results from the INCUR Study.

Objectives: Pain is very common among older persons living in nursing home, affecting 45% to 80% of residents, interfering with daily activities and quality of life. Aims of the study are: 1) to measure the analgesics non-prescription in nursing home residents who present pain symptoms; 2) to identify the main determinants of analgesics non-prescription.

Design: Retrospective cross-sectional analysis.

Setting: Data from an observational study ('Incidence of pNeumonia and related ConseqUences in nursing home Residents' [INCUR] study).

Participants: 800 older persons living in 13 French nursing homes. Measurments: Pain symptoms were definied by one of the following criteria: i) Presence of pain affecting the individual's function in the Activities of Daily Living; ii) Presence of daily pain, and/or; iii) Severe pain measured with a visual analogue scale.

Results: Among the patients originally included in the study, 288 (36%) reported pain symptomatology (mean age 86.9 [SD 7.2] years, 220 (76%) participants women). Amongst these, 138 (47.9%) were treated with non-opioid analgesic drugs, 52 (18.1%) with opioids, and 98 (34%) did not receive any analgesic prescription. An adjusted logistic regression analysis found that the strongest determinant of analgesics non-prescription was the number of concomitantly prescribed drugs (p<0.001). Age, education, and frailty were not associated with prescription of analgesic drugs.

Conclusions: Pain undertreatment is very common among older persons living in nursing homes. The number of prescribed medications represents the most relevant risk factor for the analgesics non-prescription. Our findings document the importance of reviewing prescriptions in nursing home residents.
