Mild Traumatic Brain Injury Clinical Trial

Official title: Symptom-Targeted Approach to Rehabilitation for Concussion: STAR-C

Status Active, not recruiting

Clinical Trial Summary

Throughout the course of the wars in Iraq and Afghanistan, more than 250,000 service members sustained traumatic brain injuries, mostly characterized as mild traumatic brain injuries (mTBI) or concussions. While most with mTBI recover over days to weeks, a significant percentage continue to experience post-concussive symptoms such as headaches, cognitive difficulties, and dizziness for months to years. As a result, treatment of post-concussive symptoms after mTBI is of significant importance in the Department of Defense and Veterans healthcare systems. Several studies have shown that cognitive rehabilitation can be effective for individuals with mTBI, including Service Members and Veterans with post concussive symptoms. Cognitive rehabilitation is a type of treatment in which patients work with a therapist to improve everyday memory and thinking skills and develop strategies to reduce the impact of cognitive difficulties in their everyday lives. While these treatments have great potential benefits, protocols studied to date are time intensive, requiring up to 60 hours of treatment. These time demands are impractical for many Service Members and Veterans, and place a time-burden on clinics providing the treatment. The current study proposes to identify key ingredients of an evidence-based cognitive rehabilitation protocol to develop a streamlined version that is feasible and acceptable to Service Members and Veterans. This briefer protocol will increase the number of Service Members and Veterans who can access treatment. To accomplish this goal the investigators will first spend six months analyzing manualized treatments from a successful cognitive rehabilitation intervention developed for Service Members. The investigators will analyze manuals using a framework developed to identify active ingredients in rehabilitation. Based on those results the investigators will develop a manualized streamlined treatment protocol, which the investigators will deliver to 25 Service Members and 50 Veterans over 18 months in person or via telehealth. The investigators will determine feasibility and acceptability of this intervention, and collect preliminary efficacy data. The project addresses access to therapy services and enhanced treatment compliance, a key barrier to participation in cognitive rehabilitation by Veterans and Service Members with TBI. Additionally, although this study focuses on Service Members and Veterans with mTBI, the investigators expect that this streamlined intervention can also be translated to civilian populations with mTBI.

Clinical Trial Description

Background The proposed work addresses the FY17/18 PH/TBIRP CTRR-CTA Focus Area of Cognitive Rehabilitation. The study will generate new knowledge about optimal cognitive rehabilitation prescription patterns, specifically frequency (number of days), intensity (number of hours per day), and type (active ingredients). The study outcome will be a treatment protocol (STAR-C) that can be delivered efficiently and effectively in person or via telehealth, to minimize functional limitations after mTBI and maximize treatment accessibility. The STAR-C study has features of a pragmatic trial: all individuals with mTBI are invited to enroll, regardless of co-morbidities; the primary outcome is clinically meaningful and does not require special equipment or tests; aspects of the intervention will be flexible so clinicians can tailor intervention to their clients; and there are no formal strategies to ensure compliance. Also consistent with pragmatic trial methods, the investigators will include individuals from heterogeneous practice settings (DoD and VA), and use standard-of-care outcome measures. Mild traumatic brain injury (mTBI) is a widely acknowledged cause of morbidity among Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) warfighters. Several recent studies provide incidence estimates for mTBI among combat deployed troops serving in support of OEF/OIF. In a recent population cohort study, 4.9% of over 2,500 Army infantry soldiers reported mTBI with loss of consciousness, and another 10.3% reported mTBI with altered mental status. In one cross-sectional prevalence study of OEF/OIF Service Members, 12% of the sample of over 2,200 respondents to a mail survey reported a history consistent with mTBI during deployment. Recent surveillance data obtained by the Defense and Veterans Brain Injury Center (DVBIC) from electronic medical records indicate that over the past 10 years, more than 250,000 active duty Service Members have reported sustaining a TBI, with the majority of these being mild in severity. As Service Members separate from active duty or reserve duty status, their treatment can transition to the Veterans Health Administration (VHA), which also tracks epidemiologic data. In Fiscal Year (FY) 2014, 7% of Iraq and Afghanistan War Veterans seen in the VHA system carried a diagnosis of TBI. According to Taylor et al, the prevalence of TBI diagnosis in the VA healthcare System has remained consistent since tracking began around 2009, despite changes in incidence in the DoD following the reduction of combat operations in Iraq and Afghanistan. While mTBI is generally associated with a good prognosis for recovery, a percentage of individuals experience persistent symptoms following mTBI such as headache, dizziness and/or cognitive difficulties. The frequency of functional cognitive complaints and protracted course of symptoms are especially common in individuals with mTBI and mental health comorbidities. Regardless of the exact etiology of the symptoms, long-term cognitive complaints can impact Service Members' ability to carry out their military duties and negatively impact military readiness. Given that the central tenet of military medicine is to maintain force readiness, symptoms that affect a Service Member's ability to carry out their duties without restriction remain an important focus of treatment within the DoD Healthcare System. For those individuals transitioning to the VA Healthcare system, effective treatment of post-concussive symptoms remains a priority. Taylor and colleagues demonstrated that VA healthcare utilization and associated costs were higher in individuals with a diagnosis of TBI compared to those without such a diagnosis (Cohen's d = .40), and although the prevalence of TBI diagnosis has remained constant, the number of individuals transitioning to the VA continues to rise. The US Department of Defense (DoD) and Veterans Health Administration (VHA) have invested significant resources in clinical treatment and treatment research for mTBI to address this important need. There is strong evidence that cognitive rehabilitation can help reduce functional limitations for individuals with persistent cognitive symptoms after mTBI. This includes evidence from the recent DVBIC-funded Study of Cognitive Rehabilitation Effectiveness (SCORE). SCORE was a randomized controlled trial with four treatment arms: psychoeducational intervention, computer-based cognitive rehabilitation, therapist-directed cognitive rehabilitation, and a combination of therapist-directed cognitive rehabilitation plus psychotherapeutic intervention. The largest gains in functional gains were in the last two groups - i.e., when cognitive rehabilitation was delivered by a clinician, with or without psychotherapy - and benefits were maintained 3 months after treatment. SCORE was an important advance in cognitive rehabilitation for mTBI, but it had one significant limitation: the study protocol required 10 hours of individual and group therapy per week for 6 weeks. Such an extended time commitment limits the number of Service Member s and Veterans who could access treatment and increases the likelihood of patient dropout before treatment completion. As such, a shorter version of SCORE would be more practical, but until recently the investigators did not have a systematic method of identifying elements to retain or omit. A new system for classifying rehabilitation treatments, the Rehabilitation Treatment Specification System, offers a mechanism for streamlining SCORE based on treatment principles, treatment theory, and empirical evidence. The RTSS was developed by a multidisciplinary group of rehabilitation specialists, to provide a clear and rigorous system for defining, classifying, and measuring rehabilitation treatments. The RTSS project was motivated by the lack of information about rehabilitation treatment methods, not only in research studies but also in clinical practice. While there are several systems for describing patient and study characteristics, and systems for classifying goals of treatment, these systems describe the who and what of rehabilitation. The treatments themselves, however, often are described only in terms of duration of a particular service (e.g., hours of speech therapy), or by the problems they are intended to treat (e.g., cognitive rehabilitation). What these systems do not tell us is the how of rehabilitation: what the clinician does or provides to a patient in a therapy session. The RTSS is intended to organize treatments according to these clinician actions, specifically clinician actions that are known or hypothesized to account for changes in patient functioning. Application of the RTSS to SCORE will improve efficiency and effectiveness in three ways: 1. Ensuring a match between ingredients and targets. 2. Identifying themes across treatment activities. 3. Adding volitional ingredients. Objectives/Specific Aims/Hypotheses: The project aim is to use the RTSS to develop a streamlined version of the SCORE protocol (STAR-C), and then administer the STAR-C protocol to Service Members and Veterans with mTBI in person and via telehealth. The long-term goal is to improve access to cognitive rehabilitation services for Service Members, Veterans, and civilians with mTBI, to maximize return to activities and participation in meaningful life roles. Specific objectives are: - Objective #1: To identify core ingredients and targets in SCORE and use these to develop a Core-SCORE protocol that can be delivered 3 hours per week X 3 weeks. - Objective #2: To complete an implementation study of STAR-C. - Objective #3: To collect preliminary effectiveness data for a future clinical trial comparing in-person STAR-C treatment to telehealth delivery. Because access to services can be a major barrier for Service Members and Veterans, the investigators see this as a critical next step to increase access to care to Service Members and Veterans, as well as potential translation to civilian populations. Study Design The investigators propose an implementation study, as recommended when a previous intervention (i.e. SCORE cognitive rehabilitation trial) was successful but in a different setting than the one of interest. The SCORE results serve as pilot data for this study. The proposed study has three phases: - Phase I (6 months): Analyze SCORE protocol using the RTSS manual to identify active ingredients and targets; and develop and manualize STAR-C protocol. Concurrently with protocol development and manualization, The investigators will complete all regulatory and Human Subjects procedures required for Phase II. - Phase II (18 months): Implement STAR-C. Once patients are referred and pass the screening, they will be invited to participate in the study and consented using standard, approved procedures. - Phase III (6 months): Complete collection of post-intervention implementation outcome and effectiveness data. Prepare application for a clinical trial comparing in-person to telehealth delivery of STAR-C Target Population The target population will be 75 adults with mTBI: 25 active duty Service Members (SMs) from the Brain Injury Rehabilitation Service at Brooke Army Medical Center (BAMC), and 50 Veterans from the San Antonio Polytrauma Rehabilitation Center at the South Texas Veterans Health Care System. mTBI will be defined according to criteria in the VA/DoD Clinical Practice Guideline for the Management of Concussion-Mild Traumatic Brain Injury and the Ohio State University TBI Identification Method (OSU TBI-ID). The treatment sample will consist of consecutive referrals to the clinic who meet inclusion criteria and consent to participate. Although our target enrollment is 75 individuals, the investigators anticipate that there will be some expected attrition. To address this issue, the investigators will recruit up to 34 SMs and 68 Veterans to ensure recruitment of the target population. ;
