Assessing head-injury survivors of motor vehicle crashes at discharge from trauma care

Characterization and Treatment of Chronic Pain After Traumatic Brain Injury-Comparison of Characteristics Between Individuals With Current Pain, Past Pain, and No Pain: A NIDILRR and VA TBI Model Systems Collaborative Project

OBJECTIVE

To estimate the prevalence of chronic pain after traumatic brain injury (TBI) and identify characteristics that differ from those without chronic pain.

SETTING

Community.

PARTICIPANTS

A total of 3804 TBI Model Systems (TBIMS) participants who completed the Pain Survey at TBIMS follow-up.

DESIGN

A multisite, cross-sectional observational cohort study.

MAIN OUTCOME MEASURES

Functional outcomes, pain experience, and treatment.

RESULTS

46% reported current chronic pain, 14% reported past (post-injury) chronic pain, and 40% reported no chronic pain. Bivariate differences in sociodemographic and injury characteristics between the 3 pain groups were generally small in effect size, reflecting little clinical difference. However, medium effect sizes were seen for all functional outcomes, such that individuals with current chronic pain had worse functional outcomes compared with individuals in the past pain or no pain groups. Treatment utilization rates were higher for individuals with current chronic pain compared with past pain, with medical treatments being most frequently utilized. Individuals with past pain perceived more improvement with treatment than did those with current chronic pain as represented by a large effect size.

CONCLUSIONS

Chronic pain affects approximately 60% of those living with TBI. The implications of chronic pain for functional outcomes support inclusion of pain metrics in prognostic models and observational studies in this population. Future research is needed to proactively identify those at risk for the development of chronic pain and determine the efficacy and access to pain treatment.

The prevalence and characteristics of shoulder pain after traumatic brain injury

Objective: To determine the prevalence and characteristics of shoulder pain in people with traumatic brain injury participating in inpatient rehabilitation and to compare the clinical presentation with that of people with stroke.

Design: A prospective comparative study.

Setting: Six metropolitan rehabilitation units.

Subjects: Eighty-seven people with traumatic brain injury and 52 people with stroke took part in the study.

Main measures: Assessment of shoulder pain, range of motion, strength and function was conducted on admission and, for the subjects with traumatic brain injury, at discharge if rehabilitation exceeded two weeks.

Results: The prevalence of shoulder pain in people with traumatic brain injury was 62%, which was comparable with the 69% of subjects with stroke that experienced shoulder pain (odds ratio 0.72, 95% confidence interval 0.34 -1.5). Fracture in the shoulder complex and passive shoulder external rotation range of motion were the best predictors for shoulder pain after traumatic brain injury. This was different from the subjects with stroke for which the best predictors were passive shoulder flexion range of motion and length of acute hospital stay.

Conclusion: There is a relatively high prevalence of shoulder pain after traumatic brain injury. Trauma to the shoulder complex contributes to shoulder pain after traumatic brain injury, making clinical presentation different from people with stroke. The findings support the need for greater attention in the management of shoulder pain after traumatic brain injury.

Prevalence and consequences of positive blood alcohol levels among patients injured at work

Aims:

The aim of this study was to characterize positive blood alcohol among patients injured at work, and to compare the severity of injury and outcome of blood alcohol concentration (BAC) positive and negative patients.

Settings and Design:

A retrospective cohort study was performed at a Level 1 academic trauma center. Patients injured at work between 01/01/07 and 01/01/12 and admitted with positive (BAC+) vs negative (BAC−) blood alcohol were compared using bivariate analysis.

Results:

Out of 823, 319 subjects were tested for BAC (38.8%), of whom 37 were BAC+ (mean 0.151 g/dL, range 0.015-0.371 g/dL). Age (41 years), sex (97.2% men), race, intensive care unit (ICU) and hospital length of stay (LOS), and mortality were similar between groups. Nearly half of BAC+ cases were farming injuries (18, 48.6%): Eight involved livestock, five involved all-terrain vehicles (ATVs), three involved heavy equipment, one fell, and one had a firearm injury. Eight (21.6%) were construction site injuries involving falls from a roof or scaffolding, five (13.5%) were semi-truck collisions, four (10.8%) involved falls from a vehicle in various settings, and two (5.4%) were crush injuries at an oilfield. BAC+ subjects were less likely to be injured in construction sites and oilfields, including vehicle-related falls (2.3 vs 33.9%, P < 0.0001). Over half of BAC+ (n = 20, 54%) subjects were alcohol dependent; three (8.1%) also tested positive for cocaine on admission. No BAC+ subjects were admitted to rehabilitation compared to 33 (11.7%) of BAC− subjects. Workers’ compensation covered a significantly smaller proportion of BAC+ patients (16.2 vs 61.0%, P < 0.0001).

Conclusions:

Alcohol use in the workplace is more prevalent than commonly suspected, especially in farming and other less regulated industries. BAC+ is associated with less insurance coverage, which probably affects resources available for post-discharge rehabilitation and hospital reimbursement.

The transition from hospital to home for individuals with acquired brain injury: a literature review and research recommendations

PURPOSE

To review the literature relating to the transition from hospital to home for individuals with acquired brain injury (ABI) and make recommendations concerning the future direction of transition-specific research.

METHOD

Relevant research articles were identified through searching existing database systems and by reviewing the reference lists of identified articles. Only articles in which the results directly related to individuals with ABI from the time of discharge to 1 year post-discharge were included in the review.

RESULTS/DISCUSSION

A total of 50 articles were identified as meeting the criteria for inclusion in the review. The methodological quality of included articles was evaluated using a set of specific criteria. The articles were classified into the following categories: (i) The perspectives of individuals with ABI and their caregivers; (ii) outcomes for individuals with ABI following transition; (iii) post-discharge services; and (iv) transitional living services/programmes. The majority of articles were based on samples of individuals with stroke, typically aged over 65 years. A common theme identified in the review was that the transition from hospital to home is typically perceived as an exciting yet difficult period for individuals and their families and as such, post-discharge support is critical.

CONCLUSION

Further ABI transition-specific research is necessary in order to: (i) Develop a comprehensive theoretical framework of the transition phase; and (ii) facilitate both the validation of current intervention strategies and the development of innovative/tailored intervention approaches.

Pain pathoetiology after TBI: neural and nonneural mechanisms

Individuals recovering from traumatic brain injury (TBI) frequently experience acute and chronic pain. Their pain experience is the net effect of many interacting and very complex physiologic, biochemical, and psychological mechanisms involving both the peripheral and central nervous system. This article reviews the basics of neural mechanisms and pathways of pain after TBI, and discusses clinical implications. Numerous intracranial and extracranial tissues must be considered in the evaluation of pain after TBI, with the specific mechanism of trauma influencing the anatomic distribution of injuries. The differential diagnosis usually falls into one of the following pathoetiologic classifications: primary or secondary musculoskeletal, vascular, visceral, and neural pain syndromes.
