BackgroundPain and mental health concerns are prevalent among veterans. While the majority of research has focused on chronic pain as an entity, there has been little work directed towards investigating the role of neuropathic pain in relation to psychological comorbidity. As such, we hypothesised that participants with signs of neuropathic pain would report higher levels of psychological distress and diminished self-rated health compared to those without a neuropathic component.MethodsA retrospective review of standardised questionnaires (PainDETECT Questionnaire, Post-traumatic Stress Disorder Checklist-Civilian, the Hospital Anxiety and Depression Scale, and EuroQOL Visual Analogue Scale) administered to injured soldiers. The participants were classified into three groups according to the PainDETECT questionnaire: non-neuropathic pain, possible neuropathic pain and definite neuropathic pain.ResultsFifty-three participants were included. The Post-traumatic Stress Disorder Checklist-Civilian score was in median (interquartile range) 26 (22-31), the Hospital Anxiety and Depression Scale score was 4 (2-6.5) and 2 (1-5) for anxiety and depression respectively. Evidence of neuropathic pain correlated positively with the Post-traumatic Stress Disorder Checklist-Civilian score (rho = 0.469, P < 0.001) and Hospital Anxiety and Depression Scale subscale for anxiety score (rho = 0.357, P = 0.009), and inversely with the EuroQOL Visual Analogue Scale score (rho = -0.361, P = 0.008). In multivariate regression analyses, the associations remained when adjusting for socio-demographics and clinical characteristics.ConclusionsThe results from the present study suggest that neuropathic pain is related to increased psychological distress and deterioration in self-rated health in injured soldiers.© 2015 The Acta Anaesthesiologica Scandinavica Foundation.
