Complexity Assessed by the INTERMED in Patients With Somatic Symptom Disorder Visiting a Specialized Outpatient Mental Health Care Setting: A Cross-sectional Study

This study demonstrates that patients with SSD form a high-complex group, with higher scores compared with literature about multiple sclerosis, rheumatoid arthritis, or patient waiting for a liver transplant. INTERMED outcomes indicate a need for extensive diagnostic procedures and integrated multidisciplinary care for patients with SSD. Attention should especially be paid to mental disorders (depression and anxiety), given their association with high complexity.
