Pharmacological treatment of pain in Swedish nursing homes: Prevalence and associations with cognitive impairment and depressive mood.

Objectives: Chronic pain is highly prevalent in nursing home residents and often occurs with depression as well as cognitive impairment, which can severely influence and limit the expression of pain.

Methods: The present cross-sectional study aimed to estimate the prevalence of pain, depressive mood, and cognitive impairment in association with pharmacological treatment against pain and depressive symptoms among Swedish nursing home residents.

Results: We found an overall pain prevalence of 52.8%, a prevalence of 63.1% for being in a depressive mood, and a prevalence of cognitive impairment of 68.3%. Among individuals assessed to have depressive mood, 60.5% were also assessed to have pain. The prevalence of pharmacological treatment for pain was 77.5 and 54.1% for antidepressants. Prescription of pharmacological treatment against pain was associated with reports of currently having pain, and paracetamol was the most prescribed drug. A higher cognitive function was associated with more filled prescriptions of drugs for neuropathic pain, paracetamol, and nonsteroidal anti-inflammatory drugs (NSAIDs), which could indicate an undertreatment of pain in those cognitively impaired.

Conclusion: It is important to further explore the relationship between pain, depressive mood, and cognitive impairment in regard to pain management in nursing home residents.
