Background

Although proper pain treatment may require opioids, discussion continues about possible undertreatment or overtreatment in persons with advanced dementia.

Objective

To investigate the prevalence of pain, frequency of opioid prescription use, and factors associated with strong opioid prescription use in nursing homes.

Design

Cross-sectional study.

Setting and subjects

Eighteen Norwegian nursing homes; 327 persons with advanced dementia and behavioral disturbances participated.

Methods

Potential factors associated with strong opioid prescription use were assessed: demographics (age, gender), medical conditions (comorbidity, number of medications), pain (Mobilization-Observation-Behaviour-Intensity-Dementia-2 Pain Scale ≥ 3, pain-related diagnoses, analgesic prescription use), functioning (activities of daily living, Mini-Mental State Examination) and behavior (Neuropsychiatric Inventory-Nursing Home version, Cohen-Mansfield Agitation Inventory). Factors with P < 0.10, age, and gender were included in multivariate regression analysis.

Results

The prevalence of moderate to severe pain was 62.1%. Of all participants, 19.3% (N = 63) were prescribed opioids, and of these, 79.4% (N = 50) were still in pain; 66.7% of the opioid prescriptions were less than or equal to the lowest dosage of fentanyl patches (12 mcg/h) or buprenorphine (5 or 10 mcg/h). Pain (odds ratio [OR] = 1.26, 95% confidence interval [CI] = 1.12-1.42), total number of pain-related diagnoses (OR = 1.47, 95% CI = 1.14-1.90), and depression and anxiety (OR = 1.05, 95% CI = 1.01-1.11) were positively associated with an opioid prescription. Stroke was negatively associated (OR = 0.43, 95% CI = 0.19-0.99).

Conclusions

Strong opioid prescription use was mainly associated with pain. However, in this population, despite the relatively prevalent use of strong prescription opioids, pain was still prevalent. This emphasizes the challenge of proper pain treatment and need for regular evaluation of pain and pain management.
