Summary Introduction In 2007, the Office of the Assistant Secretary of Defense issued guidance to routinely monitor post concussive symptoms following mild traumatic brain injury (mTBI). Subsequent clinical practice guidelines published as early as 2009 further underscored the importance of routine symptom monitoring following mTBI using standardized assessments such as the Neurobehavioral Symptom Inventory (NSI), though the NSI was not specifically recommended until 2015. The study objective was to describe the frequency of NSI administration, as documented in the Military Health System (MHS) electronic medical record (EMR), within one year after mTBI diagnosis among post-9/11 Active-Duty Service Members. Materials and Methods Data for this effort were extracted from the Military Health System (MHS) Data Repository and used to identify Service Members whose first mTBI (i.e., index) was documented between Fiscal Years 2002 and 2021 (index TBI; n = 150,976). Members were excluded from the cohort for a history of a more severe TBI (n = 128,253) and/or a catastrophic injury (e.g., spinal cord injury; n = 3,805). Members were matched with data from completion of the NSI that was contained within the DoD TBI portal. The cohort was further evaluated to determine the frequency of documented NSI administration within one year of the index mTBI date. Results Among those with an index mTBI meeting inclusion criteria, 3,351 (2.2%) Service Members had an NSI documented within the EMR. When filtered to NSI surveys completed within 1 year of the index mTBI date, 1,182 (0.78%) NSIs were recorded. The prevalence of a matched NSI increased as time went on, with the highest number administered in 2019. Conclusions Findings suggest relatively infrequent administration and documentation of the NSI following mTBI. System- and individual-level barriers may have played a role in this. Increased understanding regarding barriers and facilitators to administering and documenting the NSI within the EMR are needed to inform future implementation efforts to further measurement-based care among Service Members.
