Abstract

Abstract: Introduction: Depression and anxiety is known to associated with insomnia. Chronic pain is also well known to be associated with insomnia. However, relationship among insomnia and anxiety and depression is not well understood. Here We conducted a retrospective cohort study whether improvement insomnia could affect chronic pain release. Methods: Patients with chronic pain suffering for more than three months, who first visited in our pain management clinic in Shiga University of Medical Science, Otsu, Japan during 09/25/2013-01/26/2017, were included in this study. Patients were asked to complete the same questionnaire at their first visit and six-month later.We designate pain release as 30% and over improvement in numerical rating scale (NRS) for pain release.We define improvement insomnia as subjects with Athene insomnia scale (AIS) ≥6 at the first visit became AIS <6 six-month later.We also evaluated patients' psychotic conditions by Questionnaires for anxiety and depression: HADS (Anxiety and depression) and PCS (Pain Catastrophizing score) for negative cognition, respectively. We conducted logistic regression analysis as for dependent variable was pain release. Results: Characteristics data: n=47, mean age: 53.53±15.45, male rate: 45%, BMI: 22.81±3.49, NRS: 5.45±1.85, AIS: 8.94±2.73, HADSA: 6.04±2.57, HADSD: 6.06±2.64, PCS: 30.70±8.70, housemate rate: 81%, more than junior college graduated level: 53%, employment rate: 62%, annual income over 4oo million yen /year: 62%, antidepressant use; 26%, benzodiazepine use:11%.Logistic Regression odds ratio (OR) with 95% confidence intervals (95%CI) for relationship of improvement insomnia and not with chronic pain were unadjusted OR: 3.600 (95%CI: 1.007-12.865) and adjusted OR: 3.078 (95%CI 0.779-12.161) (adjust for PCS.) Conclusion: We showed improvement in insomnia can affect pain release in the pain therapy, and PCS improvement may be also association with chronic pain release. Support:
