The Mental Health Outcomes and Cost Estimates of Korean Medicine for Anxiety Disorder Patients.

This study aimed to examine the associations between improved QoL and reduced clinical symptoms and KM in patients with anxiety disorders. The medical records of patients with anxiety who were treated with KM (acupuncture, psychotherapy, Chuna therapy, aromatherapy, or herbal medicine) for at least 4 weeks were retrospectively analyzed.

The total costs for each item were calculated in terms of NHIS-covered costs and patients' out-of-pocket costs from the perspective of the healthcare system. The medical records of 67 patients were evaluated. The KM treatments were found to be associated with decreased anxiety (STAI X-1; STAI X-2; BAI,
