The mediating effect of sleep disturbance on the relationship between non-malignant chronic pain and suicide death.

View Abstract

IMPORTANCE

Few studies have examined the relationship between non-malignant chronic pain (NMCP) and suicide death and even fewer have specifically explored what role sleep disturbance might play in the association between NMCP and suicide death.

OBJECTIVE

To assess whether sleep disturbance mediates the relationship between NMCP and suicide death.

DESIGN

This case-control study included 2,674 individuals who died by suicide between 2000-2013 (cases) and 267,400 matched individuals (controls).

SETTING

Eight Mental Health Research Network (MHRN)-affiliated healthcare systems.

PARTICIPANTS

All cases and matched controls were health plan members for at least 10 months during the year prior to the index date.

MAIN OUTCOMES AND MEASURES

Sociodemographic data and diagnosis codes for NMCP and sleep disorders were extracted from the MHRN's Virtual Data Warehouse. Suicide mortality was identified using ICD-10 codes from official government mortality records matched to health system records.

RESULTS

After accounting for covariates, there was a significant relationship between NMCP and sleep disturbance; those who were diagnosed with NMCP were more likely to develop subsequent sleep disturbance. Similarly, sleep disturbance was significantly associated with suicide death. Finally, a significant indirect effect of NMCP on suicide death, through sleep disturbance, and a non-significant direct effect of NMCP on suicide death provide support for a fully mediated model.

CONCLUSIONS AND RELEVANCE

There is a need for clinicians to screen for both sleep disturbance and suicidal ideation in NMCP patients and for health systems to implement more widespread behavioral treatments that address comorbid sleep problems and NMCP. This article is protected by copyright. All rights reserved.
