A Battery of Easily Accessible, Simple Tools for the Assessment of Concussion in Children

Study design: In total, 568 clinic outpatients aged 10-18 years were sorted into 3 groups: 316 had never been concussed, 162 had ever been concussed before 8 weeks earlier, and 90 had been recently concussed within 8 weeks. At initial and any subsequent visits, a neurologic examination and 4 procedures were performed: Stick Drop, Wall Ball, Sharpened Modified Romberg (SMR), and Animal Naming. Analysis included inter-group and intra-person performance differences using a series of t tests on the Stick Drop, Wall Ball, SMR, and Animal Naming.

Results: The recently concussed group performed worse (P < .01 for all) on Stick Drop, total Wall Ball bounces and drops, and SMR compared with never-concussed and ever-concussed groups. This effect for Stick Drop, SMR, and Wall Ball but not Animal Naming persisted beyond the 4 weeks commonly stated to define recovery. Of 59 recently concussed subjects who returned for ≥1 visit, there were improvements in Stick Drop average (P = .004) and maxima (P = .02) as well as SMR (P = .01) but not Animal Naming between initial and subsequent visits.

Conclusions: This novel, rapid testing battery distinguished groups of children ages 10-18 years who had and had not experienced a recent concussion. A view that physical concussion symptoms resolve within a month of injury may be incomplete. Deployment of this readily available, inexpensive and non-proprietary battery should be compared with other tools and studied further in serial assessments.

Abstract

Description:

In September 2019, the U.S. Department of Veterans Affairs (VA) and the U.S. Department of Defense (DoD) approved a new joint clinical practice guideline for assessing and managing patients with chronic insomnia disorder and obstructive sleep apnea (OSA). This guideline is intended to give health care teams a framework by which to screen, evaluate, treat, and manage the individual needs and preferences of VA and DoD patients with either of these conditions.

Methods:

In October 2017, the VA/DoD Evidence-Based Practice Work Group initiated a joint VA/DoD guideline development effort that included clinical stakeholders and conformed to the Institute of Medicine's tenets for trustworthy clinical practice guidelines. The guideline panel developed key questions, systematically searched and evaluated the literature, created three 1-page algorithms, and advanced 41 recommendations using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system.

Recommendations:

This synopsis summarizes the key recommendations of the guideline in 3 areas: diagnosis and assessment of OSA and chronic insomnia disorder, treatment and management of OSA, and treatment and management of chronic insomnia disorder. Three clinical practice algorithms are also included.

The National Institutes of Health has estimated that insomnia and obstructive sleep apnea (OSA) are 2 of the most common sleep disorders in the general U.S. population and in the military and veteran populations (1). Insomnia symptoms are the most common sleep symptoms among U.S. adults, occurring in approximately 20% to 30% of adults, and the prevalence of chronic insomnia disorder ranges from 6% to 10% (2–6). The prevalence of OSA ranges from 9% to 38% and is associated with older age, higher body mass index, male sex, and menopause.

Sleep disorders are more prevalent in the populations served by the U.S. Department of Veterans Affairs (VA) and the U.S. Department of Defense (DoD) than in the general civilian population. In the RAND report “Sleep in the Military: Promoting Healthy Sleep Among U.S. Servicemembers,” 48.6% of military personnel surveyed had poor sleep quality (Pittsburgh Sleep Quality Index score >5) (7). The prevalence of insomnia symptoms has been reported to be as high as 41% in service members deployed to combat and 25% in noncombatants (8). In a large cohort of soldiers preparing for deployment, 19.9% met criteria for insomnia according to the Insomnia Severity Index (ISI) (8). A more recent study evaluated the incidence of insomnia and OSA in the entire population of U.S. Army soldiers from 1997 to 2011 (9) and showed unprecedented increases in the incidence of both conditions (652% and 600%, respectively) during this period. In military personnel referred for sleep evaluations, sleep-disordered breathing is the most frequently diagnosed disorder, and some studies have found that military personnel have high rates of comorbid insomnia and OSA (10, 11). Further, military personnel with sleep disorders often also have posttraumatic stress disorder (PTSD), symptoms of anxiety and depression, and traumatic brain injury, which can complicate diagnosis and management (11–13).

Sleep disturbances are also common in veterans (14–16). Similar to findings from active-duty service members, the National Veteran Sleep Disorder Study found that the number of veterans diagnosed with sleep disorders increased nearly 6-fold from 2000 to 2010. In this study, 4.5% of veterans were diagnosed with sleep-disordered breathing, and 2.5% were diagnosed with insomnia. However, the actual prevalence of insomnia disorder among veterans is likely to be considerably higher (17) because it is often not documented in the medical record (18, 19). Comorbid PTSD was associated with a 7.6-fold greater risk for OSA and a 6.3-fold greater risk for insomnia (15). Because veterans have high rates of cardiovascular disease and PTSD, and because OSA is more prevalent in patients with these disorders (20), there is likely a large percentage of veterans who have not yet been diagnosed with OSA (21).
