Abstract: Objective: The purpose of this study was to assess the rates of chronic, noncancer pain conditions in patients with schizophrenia or bipolar disorder within the Veterans Health Administration (VHA) System.Method: This cross-sectional study used administrative data extracted from VHA treatment records of all individuals receiving VHA services in fiscal year 2008 (N=5, 195,551). The associations between severe psychiatric disorders (schizophrenia and bipolar disorder) and chronic pain (arthritis, back pain, chronic pain, migraine, headache, psychogenic and neuropathic) were evaluated using a series of logistic regression analyses.Results: Veterans with schizophrenia [odds ratio (OR)=1.21] and bipolar disorder (OR=2.17) were significantly more likely to have chronic pain overall relative to veterans without these psychiatric conditions.
