evaluation of military service and family members for post concussive and posttraumatic stress symptoms

Conditions: TBI (Traumatic Brain Injury)

Summary: this protocol is designed to facilitate the recruitment, screening and registry of military service members (sms) and individuals eligible for care in the department of defense (dod) healthcare system. this protocol will serve as an entry point for sms, retirees and other beneficiaries, to facilitate their participation in center for neuroscience and regenerative medicine (cnrm)-sponsored clinical research studies at participating cnrm sites. specifically, this protocol will be comprised of an initial evaluation of participants, to include questionnaires, a blood draw, and neuroimaging. this evaluation will enable investigators to direct participants to cnrm-sponsored natural history, observational, or interventional protocols that are most relevant to the individual interests and needs of each participant. other approved cnrm protocols may continue to recruit participants directly into their respective studies, and may refer participants to this study. the objective of this protocol is to develop a broad-spectrum military subject recruitment database that will collect and store preliminary data on research participants who are interested in and potentially eligible for current and future cnrm sponsored studies. the effectiveness of the recruitment methods utilized in this protocol will be evaluated to determine the most successful outreach approaches and recruitment tools for the enrollment of participants, including both active and reserve component sms along with others who are eligible for care in the dod healthcare system, who have experienced traumatic brain injury (tbi), psychological health (ph) concerns, or are interested in participating in studies as controls. control participants may include (i) those with exposure to primary blast without the development of tbi, (ii) those with physical injuries without experiencing head injury, and (iii) healthy participants (non-injured, non-tbi, non-ph).

uniformed services university of the health science (usuhs), including the clinical research unit, (cru) clinical psychophysiology and psychopharmacology laboratory (cppl); and walter reed national military medical center (wrnmmc), including defense and veterans brain injury center (dvbic) and barl. participants may also be enrolled in the abbreviated pathway from the cnrm site at twinbrook, although other study procedures will not occur there. the study will be composed of two research pathways: (i) a standard pathway and (ii) an abbreviated pathway. prior to enrollment, both pathways will pre-screen potential participants to assess eligibility for the current study and for the protocol wrnmmc 353853. information on the prescreen form is collected to assist with scheduling study assessments such as patient interviews and placing orders for imaging and blood collection. participants eligible for the wrnmmc 353853 will have the option to dual enroll into that study. parenthetically, it should be noted that wrnmmc 353853 recruits inpatients from the neurology and neurosurgery service, as well as the neurology clinic at wrnmmc; while the current study encompasses many of the same procedures as wrnmmc 353853, the intent of the current study is to recruit a much broader population, including healthy controls, those with primary psychological health concerns, and those with blast exposure who do not necessarily meet criteria for tbi. to facilitate accrual of our cohort, we will actively recruit from a much broader range of settings, including primary care, behavioral health, and orthopedics and rehabilitation clinics at wrnmmc, and a wide array of clinics and services at fbch, in addition to using cnrm's social media and other web-based efforts. applicable study procedures will depend on the pathway for enrollment, diagnostic certainty, and logistic considerations such as distance from participating sites, availability of scanners, and feasibility of transport. standard pathway: visit procedures for this pathway will be conducted at the participating sites (fbch, usuhs, wrnmmc) and will consist of informed consent, collection of pii/phi, generation of a global unique identifier (guid) as detailed below in section 6.3.4., structured data collection of medical history, combat-related as well as any civilian injury details, symptom inventory, blood collection and validated questionnaires to assess symptoms. scale cards containing the potential responses for each of the questionnaires will be provided to participants for in-person interviews. the scales correlate to specific study data collection measures (questionnaires). the scale cards will allow the participant to view the answer choices for each measure while the study team member administers the questionnaires. the scale cards will ensure greater participant understanding during administration of the questionnaires. additionally, this pathway will include collection of venous blood and a mri of the brain for participants who consent to these elements. visit procedures will also include a physical exam, neurocognitive assessments, and exit consultation. see section 6.3 study design for further detail. abbreviated pathway: visit procedures for this pathway will consist of informed consent, collection of pii/phi, generation of a guid as detailed below in section 6.3.4., an abbreviated questionnaire for structured collection of a medical history, injury details, and validated questionnaires assessing symptoms. scale cards containing the potential responses for each of the questionnaires will be mailed to participants for telephonic interviews. the scales correlate to specific study data collection measures (questionnaires). the scale cards will allow the participant to view the answer choices for each measure while the study team member administers the questionnaires. the scale cards will ensure greater participant understanding during administration of the questionnaires. potential research participants will be enrolled in this abbreviated pathway by participating in a (i) telephonic interview or (ii) an in-person interview at twinbrook, participating sites, or at recruitment events, or through some combination of these approaches. see section 6.3 study design for further detail. objectives: the primary objective of this protocol is to facilitate recruitment of sms and those eligible for care in the dod healthcare system to cnrm sponsored clinical research at participating cnrm sites. additional aims of the study are to: * use data collected through this protocol to improve recruitment methods * coordinate the enrollment of participants in cnrm studies with the greatest relevance and interest to them, maintain longitudinal contact, and offer those who are interested the opportunity to participate in subsequent cnrm studies after enrollment in this study * use data collected through the neurocognitive assessment (nih toolbox) to better direct referral to appropriate cnrm studies * establish and maintain study specific recruitment databases containing (i) identifiable data (pii and phi) and (ii) coded research data * collect and provide blood and de-identified data to irb-approved cnrm biospecimen and informatics repositories for use in future research studies (storage procedures covered by usuhs irb protocol "biorepository and informatics warehousing", cnrm 004) * assessment of tbi and psychological stress impact on the brain via structural and functional imaging as well as diffusion tensor imaging * assess imaging and neurocognitive data for patterns that could distinguish those with ongoing symptoms vs. those who are more resilient after trauma
