Safety Considerations for the Use of Transcranial Magnetic Stimulation as Treatment for Coma Recovery in People With Severe Traumatic Brain Injury.

OBJECTIVE: For persons in states of disordered consciousness (DoC) after severe traumatic brain injury (sTBI), we report cumulative findings from safety examinations, including serious adverse events (AEs) of a repetitive transcranial magnetic stimulation (rTMS) parameter protocol in 2 different studies. PARTICIPANTS: Seven persons in states of DoC after sTBI with widespread neuropathology, but no large lesions in proximity to the site of rTMS. One participant had a ventriculoperitoneal shunt with programmable valve. METHODS: Two clinical trials each providing 30 rTMS sessions to the right or left dorsolateral prefrontal cortex, involving 300 to 600 pulses over 1 or 2 sessions daily. One study provided concomitant amantadine. Safety indicators monitored related to sleep, temperature, blood pressure, skin integrity, sweating, weight loss, infections, and seizure. RESULTS: Average changes for monitored indicators were of mild severity, with 75 nonserious AEs and 1 serious AE (seizure). The participant incurring a seizure resumed rTMS while taking antieplieptics without further seizure activity. CONCLUSIONS: Considering elevated risks for this patient population and conservative patient selection, findings indicate a relatively safe profile for the specified rTMS protocols; however, potential for seizure induction must be monitored. Future research for this population can be broadened to include patients previously excluded on the basis of profiles raising safety concerns.

Clinical information seeking in traumatic brain injury: a survey of Veterans Health Administration polytrauma care team members.

BACKGROUND: The polytraumatic nature of traumatic brain injury (TBI) makes diagnosis and treatment difficult. OBJECTIVES: To (1) characterise information needs among Veterans Health Administration (VHA) polytrauma care team members engaged in the diagnosis and treatment of TBI; (2) identify sources used for TBI related information; and (3) identify barriers to accessing TBI related information. METHODS: Cross-sectional online survey of 236 VHA polytrauma care team members. RESULTS: Most respondents (95.8%) keep at least somewhat current regarding TBI, but 31.5% need more knowledge on diagnosing TBI and 51.3% need more knowledge on treating TBI. Respondents use VHA affiliated sources for information, including local colleagues (81.7%), VHA offsite conferences/meetings (78.3%) and onsite VHA educational offerings (73.6%); however, limited time due to administrative responsibilities (50.9%), limited financial resources (50.4%) and patient care (50.4%) were prominent barriers. DISCUSSION: Medical librarians are in a unique position to develop information services, resources and other electronic tools that reflect the clinical context in which polytrauma care team members practice, and the different tasks they perform. CONCLUSION: Polytrauma care team members could benefit from additional information regarding the diagnosis and treatment of TBI. Addressing their information needs and supporting their information seeking requires a mulit-pronged approach to time and financial constraints.

Burnout and coping strategies of polytrauma team members caring for veterans with traumatic brain injury.

OBJECTIVE: The aims of this national study were to (1) examine the extent of job burnout among VA Polytrauma team members engaged in the diagnosis and treatment of traumatic brain injury (TBI); and (2) identify their coping strategies for dealing with job-related stress. DESIGN: A cross-sectional sample of 233 VA Polytrauma team members completed the Maslach Burnout Inventory (MBI) and identified strategies for coping with work stress as part of an online survey. RESULTS: VA Polytrauma team members experience moderate levels of emotional exhaustion, but low levels of depersonalization and high levels of personal accomplishment. Moreover, 24% of participants reported high levels of emotional exhaustion, which may be a precursor to job burnout. Participants who reported caring for veterans with TBI ≥50% of their time experienced higher levels of emotional exhaustion than those who spent <50% of their time (p ≤ 0.001). Five major thematic categories related to coping strategies emerged from the data: (1) connecting with others, (2) promoting a healthy lifestyle, (3) pursuing outside interests, (4) managing work environment and (5) maintaining positive thinking. CONCLUSION: Polytrauma team members caring for Veterans with TBI may be at risk for job burnout.

Prevalence and treatment of headaches in veterans with mild traumatic brain injury.

OBJECTIVES: To report the prevalence and characteristics of headaches in veterans with mild traumatic brain injury (TBI) and to describe most common treatment strategies after neurological evaluation. METHODS: We conducted a retrospective cohort study. The setting was a United States Veterans Healthcare Administration Polytrauma Network Site. The study participants consisted of 246 veterans with confirmed diagnosis of mild TBI. The main outcome measures were: Self-reported head pain occurring 30 days prior to initial mild TBI screening; headache severity measured by the Neurobehavioral Symptom Inventory; headache characteristics; and treatment prescribed by neurologists. RESULTS: The majority (74%) of veterans with a confirmed diagnosis of mild TBI (N=246), due largely to blast exposure, reported headaches in the 30 days preceding the initial mild TBI evaluation. Thirty-three percent of these veterans (N=81) were referred to neurology for persistent headaches. Of the 56 veterans attending the neurology evaluation, 45% were diagnosed with migraine headaches and 20% with chronic daily headaches. The most commonly used abortive agents were triptans (68%) and the most common preventive medications were anticonvulsants (55%) and tricyclics (40%). CONCLUSION: There was an increased prevalence of headaches in veterans with mild TBI. Most of the TBI veterans in our study group were exposed to blast injury and findings indicate that the nature of head trauma may be contributing to headaches. Findings highlight the need for developing effective headache prevention and treatment strategies for all persons with mild TBI and in particular for veterans with blast-related mild TBI.

Placebo-Controlled Trial of Familiar Auditory Sensory Training for Acute Severe Traumatic Brain Injury: A Preliminary Report.

BACKGROUND: Sensory stimulation is often provided to persons incurring severe traumatic brain injury (TBI), but therapeutic effects are unclear. OBJECTIVE: This preliminary study investigated neurobehavioral and neurophysiological effects related to sensory stimulation on global neurobehavioral functioning, arousal, and awareness. METHODS: A double-blind randomized placebo-controlled trial where 15 participants in states of disordered consciousness (DOC), an average of 70 days after TBI, were provided either the Familiar Auditory Sensory Training (FAST) or Placebo of silence. Global neurobehavioral functioning was measured with the Disorders of Consciousness Scale (DOCS). Arousal and awareness were measured with the Coma-Near-Coma (CNC) scale. Neurophysiological effect was measured using functional magnetic resonance imaging (fMRI). RESULTS: FAST (n = 8) and Placebo (n = 7) groups each showed neurobehavioral improvement. Mean DOCS change (FAST = 13.5, SD = 8.2; Placebo = 18.9, SD = 15.6) was not different, but FAST patients had significantly (P = .049; 95% confidence interval [CI] = -1.51, -.005) more CNC gains (FAST = 1.01, SD = 0.60; Placebo = 0.25, SD = 0.70). Mixed-effects models confirm CNC findings (P = .002). Treatment effect, based on CNC, is large (d = 1.88, 95% CI = 0.77, 3.00). Number needed to treat is 2. FAST patients had more fMRI activation in language regions and whole brain (P values <.05) resembling healthy controls' activation. CONCLUSIONS: For persons with DOC 29 to 170 days after TBI, FAST resulted in CNC gains and increased neural responsivity to vocal stimuli in language regions. Clinicians should consider providing the FAST to support patient engagement in neurorehabilitation.

Healthcare utilization and costs of Veterans screened and assessed for traumatic brain injury.

Approximately 15% of casualties in the Afghanistan (Operation Enduring Freedom [OEF]) and Iraq (Operation Iraqi Freedom [OIF]) conflicts received mild traumatic brain injury (TBI). To identify Veterans who may benefit from treatment, the Department of Veterans Affairs (VA) implemented a national clinical reminder in 2007 to screen for TBI. Veterans who screen positive are referred for a comprehensive TBI evaluation. We conducted a national retrospective study of OIF/OEF Veterans receiving care at VA facilities between 2007 and 2008. We examined the association of the TBI screen with healthcare costs over a 12 mo period following the initial evaluation. Of the Veterans, 164,438 met inclusion criteria: 31,627 screened positive, 118,545 screened negative, and 14,266 received no TBI screening. Total healthcare costs of Veterans who screened positive, screened negative, or had no TBI screening were $9,610, $5,184, and $3,399, respectively (p < 0.001). Understanding these healthcare utilization and cost patterns will assist policymakers to address the ongoing and future healthcare needs of these returning Veterans.

An evaluation of the Veterans Affairs traumatic brain injury screening process among Operation Enduring Freedom and/or Operation Iraqi Freedom veterans.

OBJECTIVE: To describe the early results of the U.S. Department of Veterans Affairs (VA) screening program for traumatic brain injury (TBI) and to identify patient and facility characteristics associated with receiving a TBI screen and results of the screening. DESIGN: National retrospective cohort study. SETTING: VA Medical facilities. PATIENTS: A total of 170,681 Operation Enduring Freedom and/or Operation Iraqi Freedom (OEF/OIF) Veterans who sought care at VA medical facilities from April 2007 to September 30, 2008. METHODS: Data were abstracted from VA administrative and operational databases, including patient demographics, facility characteristics, and outcomes. MAIN OUTCOME MEASUREMENTS: The main outcomes were receipt of and results of the TBI screen. RESULTS: The majority of veterans eligible received the TBI screen (91.6%). Screening rates varied by patient and facility characteristics. In all, 25% of screened veterans had probable TBI exposure, in which the majority of the exposures were blasts (85.0%). The rate of a positive TBI screen was 20.5% for the screened cohort. Male gender, service in the army, multiple deployments, and mental health diagnoses in the previous year were associated with a positive screen. CONCLUSIONS: TBI screening rates are high in VA; concomitant mental health diagnoses were highly prevalent in individuals with positive TBI screens. These data indicate that there will be a significant need for long-term health care services for veterans with TBI symptomatology.

Audiological issues and hearing loss among Veterans with mild traumatic brain injury.

We examined the prevalence, severity, etiology, and treatment of audiology problems among Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) Veterans with mild traumatic brain injury (TBI). A retrospective chart review was performed of 250 Veterans with mild TBI. Results of a comprehensive second-level mild TBI evaluation and subsequent visits to audiology were evaluated. We found the vast majority (87%) of Veterans reported some level of hearing disturbance and those involved in blast injuries reported a higher incidence of hearing disturbance than those with other injury etiologies. Audiology referrals were given to 75 Veterans and 37 attended. At this visit, Veterans reported tinnitus (75.7%) and hearing loss (59.8%). Nearly half (48.6%) of Veterans were diagnosed with conductive hearing loss, sensorineural hearing loss, or central auditory dysfunction. An additional 24.3% of Veterans had subclinical levels of auditory dysfunction. Our study has highlighted the increased prevalence of hearing loss among OIF/OEF Veterans and, thus, the need for appropriate referrals and treatment. Strategies to address perceived stigma associated with hearing loss may increase attendance at follow-up visits. Additionally, while only a third of audiograms were found to be abnormal, advanced testing resulted in a significant percentage of our population being diagnosed with auditory dysfunction.

Reliability of the physical medicine and rehabilitation resident observation and competency assessment tool: a multi-institution study.

OBJECTIVES: To assess the psychometric qualities of a method of resident physician evaluation by faculty. DESIGN: Multicenter study by seven Physical Medicine and Rehabilitation training programs. Faculty physicians observed residents in brief patient encounters or teaching sessions, rated specific competencies, and provided residents with immediate feedback. The resident observation and competency assessment form included competencies in patient care, professionalism, interpersonal and communication skills, systems-based practice, and practice-based learning and improvement. Residents and faculty rated satisfaction with the process. RESULTS: Three hundred sixty-two ratings were completed on 88 different residents. Each resident received an average of 3.8 ratings across two academic years. Overall internal consistency reliability was high (0.98); reliability of the individual competencies ranged from 0.74 to 0.76. Item means were correlated with year of training for two skill sets, with higher means for more experienced residents. The majority of participants gave high ratings of satisfaction; correlation between satisfaction ratings of attending and resident physicians was 0.63 (P < 0.01). CONCLUSIONS: The resident observation and competency assessment is a reliable method to assess resident skills in five of six general competencies. Construct validity of the tool is supported by the fact that faculty rated two skill sets higher for senior residents.
