Description
Summary:Objective Chronic overlapping pain conditions (COPCs) represent a co‐aggregation of widespread pain disorders. We characterized differences in physical and psychosocial functioning in patients with chronic migraine (CM) and those with CM and COPCs. Background Patients with CM and COPCs have been identified as a distinct subgroup of patients with CM, and these patients may be vulnerable to greater symptom severity and burden. Methods Data were extracted from Collaborative Health Outcomes Information Registry (an open‐source learning health‐care system), completed at the patients' first visit at a large tertiary care pain management center and electronic medical records. In 1601 patients with CM, the number of non‐cephalic areas of pain endorsed on a body map was used to examine the differences in pain, physical and psychosocial function, adverse life experience, and health‐care utilization. Results Patients endorsing more body map regions reported significantly worse symptoms and function across all domains. Scored on a t‐score metric (mean = 50, SD = 10), endorsement of one additional body map region corresponded with a 0.69‐point increase in pain interference (95% CI = 0.55, 0.82; p
