Understanding and meeting information needs for patients with posttraumatic stress disorder.

BACKGROUND: Posttraumatic Stress Disorder (PTSD) is a commonly occurring mental illness. There are multiple treatments for PTSD that have similar effectiveness, but these treatments differ substantially in other ways. It is desirable to have well-informed patients involved in treatment choices. A patient decision aid (PtDA) is one method to achieve this goal. This manuscript describes the rationale and development of a patient decision aid (PtDA) designed for patients with PTSD. METHODS: We conducted an informational needs assessment of veterans (n = 19) to obtain their baseline information needs prior to the development of the PtDA. We also conducted a literature review of effective PTSD treatments, and we calculated respective effective sizes. A PtDA prototype was developed according to the guidelines from the International Patient Decision Aid Standards. These standards guided our development of both content and format for the PtDA. In accordance with the standards, we gathered feedback from patients (n = 20) and providers (n = 7) to further refine the PtDA. The information obtained from patients and the literature review was used to develop a decision aid for patients with PTSD. RESULTS: Patients with PTSD reported a strong preference to receive information about treatment options. They expressed interest in also learning about PTSD symptoms. The patients preferred information presented in a booklet format. From our literature review several treatments emerged as effective for PTSD: Cognitive Therapy, Exposure Therapy, Eye Movement Desensitization Therapy, Selective Serotonin Reuptake Inhibitors, venlafaxine, and risperidone. CONCLUSION: It appears that the criteria set forth to develop decision aids can effectively be applied to PTSD. The resultant PTSD patient decision aid is a booklet that describes the causes, symptoms, and treatments for PTSD. Future work will examine the effects of use of the PTSD decision aid in clinical practice. TRIAL REGISTRATION: Clinicaltrials.gov identifier NCT00908440. Registered May 20, 2009.

A randomized controlled clinical trial of a patient decision aid for posttraumatic stress disorder.

OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Measuring use of evidence based psychotherapy for posttraumatic stress disorder.

To improve methods of estimating use of evidence-based psychotherapy for posttraumatic stress disorder in the Veteran's health administration, we evaluated administrative data and note text for patients newly enrolling in six VHA outpatient PTSD clinics in New England during the 2010 fiscal year (n = 1,924). Using natural language processing, we developed machine learning algorithms that mimic human raters in classifying note text. We met our targets for algorithm performance as measured by precision, recall, and F-measure. We found that 6.3 % of our study population received at least one session of evidence-based psychotherapy during the initial 6 months of treatment. Evidence-based psychotherapies appear to be infrequently utilized in VHA outpatient PTSD clinics in New England. Our method could support efforts to improve use of these treatments.

Comparing the stability of diagnosis in full vs. partial posttraumatic stress disorder.

We studied differences in diagnostic stability between patients with full and patients with partial posttraumatic stress disorder (PTSD). We collected self-reported symptoms of PTSD, anxiety, depression, and functioning at a Veterans Affairs mental health clinic (n = 1962). We classified patients as meeting full or partial PTSD based upon their initial assessment. We performed Kaplan-Meier survival analysis to compare stability of diagnosis over time and Cox proportional hazards models to understand how comorbid symptoms and level of functioning confounded the relationship. We performed a chart review to examine differences in treatment received by the two groups. Patients in the partial PTSD group lost their diagnosis significantly faster and at significantly higher rates than did patients with full PTSD. Comorbid symptoms contributed significantly to this difference. Mental health treatments delivered to the two groups were similar. These diagnoses appear to be different, suggesting that people with partial PTSD may benefit from a different clinical approach.
