Patient journey before and after a formal post-traumatic stress disorder diagnosis in adults in the United States - a retrospective claims study.

The PTSD diagnosis was associated with increased rates of symptoms and frequent psychiatric comorbidities, psychotherapy and pharmacological treatments received, HRU, and healthcare costs, pointing to increased patient monitoring. Within 6 to 12 months after the PTSD diagnosis, these outcomes tended to reduce, perhaps as patients were obtaining targeted and effective care.
