Patients With Neuropathic Pain Have Poor Sleep Quality

Although sleep disorders have been studied many times in neuropathic pain (NP), the effect of pain level, depression, and quality of life (QOL) on sleep quality in NP has been rarely investigated. In the present study, we aimed to investigate associations between possible quality of sleep (QOS) impairment and pain level, depression, and QOL. Average daily pain intensity, QOL, QOS, and depression status of the patients were evaluated using a 100-mm visual analog scale (VAS), the RAND 36-Item Health Survey 1.0, the Pittsburgh Sleep Quality Index, and Beck Depression Inventory (BDI), respectively. In 83.1% of patients QOS was found to be poor. We found that there was a significant difference between good and poor QOS in BDI, VAS, and RAND 36-Item Health Survey 1.0 scale's parameters, and patients with NP have poor sleep quality. Depression status is the main predictor for QOS, so pain level and QOL affect the QOS in NP. Physicians who aim healthy QOS must evaluate all characteristics of pain, depression status, and QOL in patients with NP.
