Registry-based cohort design
Analysis of insomnia symptom severity across ICD-11 chronic pain categories
Longitudinal assessment of pain intensity and bothersomeness
Insomnia symptom severity correlates with long-term pain intensity
Symptom impact is substantial across all ICD-11 chronic pain categories
Findings suggest that insomnia is often overlooked in clinical guidelines

Abstract

While the severity of insomnia symptoms appears to be equally distributed across ICD-11 chronic pain categories and has a substantial impact on the long-term intensity and bothersomeness of pain, it is largely ignored in clinical guidelines. Findings suggest that early, targeted interventions for insomnia symptoms may benefit patients.
