A Randomized Controlled Clinical Trial of a Patient Decision Aid for Posttraumatic Stress Disorder

Patient decision aids have been used in many clinical situations to improve the patient centeredness of care. A patient decision aid for patients with posttraumatic stress disorder (PTSD) has not been developed or tested. The authors evaluated the effects of a patient decision aid on the patient centeredness of PTSD treatment.

The study was a randomized trial of a patient decision aid for PTSD versus treatment as usual (control group). The participants were 132 male and female veterans who presented to a single U.S. Department of Veterans Affairs hospital with a new diagnosis of PTSD. Patient centeredness was assessed by knowledge of PTSD and its treatment, level of decisional uncertainty, and ability to state a preferred treatment option. Secondary outcomes included treatments received and PTSD symptoms in the six months after study entry.

Compared with the control group (N=65), participants who reviewed the patient decision aid (N=63) had higher scores for PTSD knowledge (p=.002) and less conflict about their choice of treatment (p=.003). In addition, participants who reviewed the patient decision aid were more likely to select and receive an evidence-based treatment for PTSD (p=.04) and had superior PTSD outcomes (p=.004) compared with the control group.

Use of a patient decision aid was associated with improvements in patient-centered PTSD treatment. The patient decision aid was also associated with greater use of evidence-based treatments and improvement of PTSD symptoms. This study suggests that clinics should consider using a patient decision aid for patients with PTSD.
