Background and study aims
Posttraumatic stress disorder (PTSD) is extremely prevalent (24.5%) in the US Department of Veterans Affairs (VA). PTSD is a major risk factor for engaging in unhealthy behaviors such as tobacco use, drug use, and alcohol misuse, and is associated with high rates of morbidity, disability and mortality (including suicide).

Based on various research, trauma-focused psychotherapy is considered the first treatment for PTSD. The US Department of VA has trained thousands of its providers to deliver trauma-focused psychotherapies for PTSD in specialty mental health and telemental health clinics. These therapies have included prolonged exposure (PE), during which trauma-related memories, feelings, and situations that have been avoided since the initial trauma can be approached in a safe environment, and cognitive processing therapy (CPT), a type of cognitive behavioural therapy which helps an individual evaluate and change upsetting thoughts that have occurred since the trauma. However, only a minority of patients with PTSD treated in VA specialty mental health settings receive trauma-focused psychotherapy. Moreover, treatment drop-out from trauma-focused psychotherapies delivered in specialty mental health care settings is high both in clinical studies (13%-39%) and routine care (36%-65%).

Written exposure therapy (WET) is a relatively new brief trauma-focused therapy developed at the VA National Center for PTSD. Patients write about their traumatic experiences following a script structured by a therapist. The protocol for WET involves one 60-minute session, followed by four 40-minute sessions. The first session includes psychoeducation, provides a treatment rationale for approaching the trauma memory, and discusses the use of writing as a means of doing so. During sessions, patients hand write about the memory of their worst traumatic event for 30 minutes, with a focus on details of the event and thoughts and feelings that occurred during the event. Feedback about the narrative is provided to the patient at the beginning of sessions 2-5. In contrast to the high drop-out rates for PE and CPT, drop-out rates for WET have ranged from 6.4%-14%. In a superiority trial conducted in a civilian population, WET was significantly more effective than not having the therapy. In a comparison of 5 sessions of WET to 12 sessions of CPT, WET was more effective than CPT. WET is considered a first treatment in the US VA/Department of Defense PTSD Clinical Practice Guidelines.

However, WET has not been delivered by tele-therapists at VA Clinical Resource Hubs (CRHs), regional telehealth hubs designed to support underperforming satellite outpatient clinics with inadequate staffing. Mental health services are delivered to Veterans via interactive video and to Veterans in their homes.

Who can participate?
Veterans enrolled in the United States Department of Veterans Affairs with a primary diagnosis of PTSD

What does the study involve?
Tele-therapists volunteer to participate in the project and their patients are sampled for six months for the evaluation. Multiple cohorts of tele-therapists will participate and the project is expected to last for two and half years. Therapists are randomized to one of two implementation strategies (WET training alone or WET training plus external facilitation) and complete a very brief survey monthly to assess their beliefs about delivering WET. Patients are sent opt-out emails and those not opting out are asked to complete two brief telephone surveys and permission to review their medical records.

What are the possible benefits and risks of participating?
Patients whose therapist was randomized to WET training plus external facilitation may be more likely to receive trauma-focused psychotherapy, which is recommended as the first line of treatment by the VA/DOD PTSD Clinical Practice Guidelines. However, there are no guarantees that patients participating in the evaluation will experience a clinical benefit. The risk to both therapists and patients is the potential loss of privacy of sensitive information.

Where is the study run from?
The VA Virtual Care QUERI Program (United States of America)

Scientific titleImplementation of written exposure therapy for PTSD in Veterans Affairs telehealth clinical resource hubs
Study acronymWETT
Study objectivesAim 1 – Compare adoption of Written Exposure Therapy (WET) by Department of Veterans Affairs Clinical Resource Hub (CRH) tele-therapists randomized to standard WET training or WET training plus external facilitation.
Hypothesis 1 (Adoption). CRH tele-therapists randomized to WET training plus external facilitation will be more likely to adopt WET than tele-therapists randomized to WET training only.
Aim 2 – Compare reach and effectiveness outcomes among patients diagnosed with PTSD treated by CRH tele-therapists randomized to standard WET training or WET training plus external facilitation.
Hypothesis 2 (Reach). Patients diagnosed with PTSD will be more likely to initiate WET if their tele-therapist was randomized to WET training plus external facilitation than if their tele-therapist was randomized to WET training only.
Hypothesis 3 (Effectiveness). Patients diagnosed with PTSD will have greater improvements in PTSD severity if their tele-therapist was randomized to WET training plus external facilitation than if their tele-therapist was randomized to WET training only.
Aim 3 – Compare implementation mechanisms of action among CRH tele-therapists randomized to standard WET training or WET training plus external facilitation, and test for mediation.
Hypothesis 4 (Mechanisms). Tele-therapists randomized to WET training plus external facilitation will be more likely to report greater increases in attitudes, self-efficacy, usability and social norms over time than tele-therapists randomized to WET training only.
Hypothesis 5 (Reach Mediation). The greater likelihood of initiating WET among patients treated by tele-therapists randomized to WET training plus external facilitation will be partially mediated by better attitudes, greater self-efficacy, usability and social norms.
Ethics approval(s)The study activities described are not being conducted as part of a research project but as part of a non-research evaluation conducted under the authority of The Department of Veteran Affairs Office of Rural Health (confirmed 28/12/2020), which does not require ethics approval as per VHA Handbook 1200.21 (Veterans Health Administration 2019) under the United States of America's law.
Health condition(s) or problem(s) studiedPosttraumatic Stress Disorder
InterventionThe interventions are not clinical interventions, they are implementation strategies designed to promote the adoption of evidence-based practice into routine care.

Implementation Strategy 1 - Therapist training in Written exposure therapy (WET) with clinical supervision of two patients.
Implementation Strategy 2 - Therapist training in WET with clinical supervision of two patients, plus a WET shared decision-making aid, a manual for remote sharing of written trauma narratives, and a virtual community of practice for six months.

Arms – The Standard WET training arm involves 6 hours of didactics and weekly clinical supervision until two patients have completed WET. The Standard WET training plus external facilitation involves 6 hours of didactics and weekly clinical supervision until two patients have completed WET and 6 months of external facilitation. External facilitation will have three main components: 1) WET shared decision-making aid, 2) manual for remote sharing of written trauma narratives, and 3) virtual community of practice. The community of practice calls will last for six months, and will be hosted by trained facilitator and a veteran with lived experience.

Randomization – The randomization of therapists will be conducted using an online list randomization app (https://www.random.org/lists/) after completion of Standard WET training.
Intervention typeOther
Primary outcome measureReach at the patient level, defined as whether the patient received the WET intervention, measured using chart reviews during the time period between the intake visit and 4 months later
Secondary outcome measures1. Clinical effectiveness at the patient level measured using the PTSD Check List for DSM-V (PCL-5) survey to assess PTSD symptom severity and the Brief Inventory of Psychosocial Functioning (B-IPF) to assess relationship functioning at baseline and 4 months
2. Adoption at the therapist level measured using chart reviews to measure what proportion of each therapist’s patients with PTSD received WET versus some other type of counseling during the six months of external facilitation
3. Mechanisms of action measured using provider surveys at 1, 2, 3, 4, 5, and 6 months after external facilitation began, including:
3.1. Self-efficacy for PTSD treatment planning
3.2. Attitude about WET
3.3. Self-efficacy for delivering WET
3.4. Usability for sharing trauma narratives
3.5. Clinical Resource Hub (CRH) therapist support for delivering WET
