3110 — A Randomized Controlled Clinical Trial of a Patient Decision Aid for Posttraumatic Stress Disorder

Watts BV, White River Junction VA; Schnurr PP, National Center for PTSD;

Patient decision aids have been used in many clinical situations to improve the patient-centeredness of care. No patient decision aid has been developed or tested in patients with posttraumatic stress disorder (PTSD). Our objective is to evaluate 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 individuals with PTSD versus treatment as usual among patients newly diagnosed with PTSD. The participants were 132 male and female veterans presenting to a single VA hospital with a new diagnosis of PTSD. Patient-centeredness was assessed in terms of participant knowledge about PTSD and its treatment, level of decisional uncertainty, and ability to state a preferred treatment option. Secondary outcomes include treatments actually received in the six months after study entry and PTSD symptom outcomes.

Compared to controls, participants who reviewed the patient decision aid had higher PTSD knowledge (p = 0.002) and less conflict about their choice of treatment (p < = 0.003). In addition, those who reviewed the patient decision aid were more likely to select and receive an evidence-based treatment for PTSD (p = 0.04), and had superior PTSD outcomes (p = 0.004).

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 improved PTSD symptom outcomes. This study suggests that use of the patient decision aid for PTSD should be considered in clinics seeing patients with PTSD.

Increased used of patient decision aids should be considered in Veterans with PTSD to improve the overall quality of care they receive.
