Follow-up issues in children with mild traumatic brain injuries

Patterns and Predictors of Health Care Utilization After Pediatric Concussion: A Retrospective Cohort Study

OBJECTIVE

To characterize types, duration, and intensity of health care utilization following pediatric concussion and to identify risk factors for increased post-concussion utilization.

METHODS

A retrospective cohort study of children 5 to 17 years old diagnosed with acute concussion at a quaternary center pediatric emergency department or network of associated primary care clinics. Index concussion visits were identified using International Classification of Diseases, Tenth Revision, Clinical Modification codes. We analyzed patterns of health care visits 6 months before and after the index visit using interrupted time-series analyses. The primary outcome was prolonged concussion-related utilization, defined as having ≥1 follow-up visits with a concussion diagnosis more than 28 days after the index visit. We used logistic regressions to identify predictors of prolonged concussion-related utilization.

RESULTS

Eight hundred nineteen index visits (median [interquartile range] age, 14 [11-16] years; 395 [48.2%] female) were included. There was a spike in utilization during the first 28 days after the index visit compared to the pre-injury period. Premorbid headache/migraine disorder (adjusted odds ratio (aOR) 2.05, 95% confidence interval [CI] 1.09-3.89) and top quartile pre-injury utilization (aOR 1.90, 95% CI 1.02-3.52) predicted prolonged concussion-related utilization. Premorbid depression/anxiety (aOR 1.55, 95% CI 1.31-1.83) and top quartile pre-injury utilization (aOR 2.29, 95% CI 1.95-2.69) predicted increased utilization intensity.

CONCLUSIONS

Health care utilization is increased during the first 28 days after pediatric concussion. Children with premorbid headache/migraine disorders, premorbid depression/anxiety, and high baseline utilization are more likely to have increased post-injury health care utilization. This study will inform patient-centered treatment but may be limited by incomplete capture of post-injury utilization and generalizability.

Sleep outcomes in pediatric mild traumatic brain injury: a systematic review and meta-analysis of prevalence and contributing factors

OBJECTIVE

The aim was to determine the prevalence of disturbed sleep in children who sustained mild traumatic brain injury (mTBI).

METHODS

We conducted electronic searches of three databases MEDLINE, PsychINFO and EMBASE against pre-determined inclusion/exclusion criteria. We used the Newcastle-Ottawa Scale to assess the risk of bias.

RESULTS

Forty-four articles met the inclusion criteria. The risk of bias was mainly rated as moderate to high. Meta-analysis revealed that prevalence of sleep disturbances decreased as the time since injury increased: 51%, 40% and 9% within 1 week, between 1 week and 1 month, and between 1 and 3 months, respectively, but increased to 21% after 3 months. The sleep symptom drowsiness followed a similar temporal pattern. Other sleep symptoms of hypersomnia (sleeping more than usual) and insomnia (trouble falling asleep and sleeping less than usual) remained stable over time. The prevalence of sleep disturbances in children with mTBI was higher than in the general population. Pre-injury sleep and older age at injury were related to worse sleep outcomes.

CONCLUSIONS

Sleep disturbances are highly prevalent in the acute phase post-mTBI. Given that disturbed sleep can impact daily functioning and recovery, routine screening and management of sleep disturbances in children who sustain mTBI is important.

Photophobia Associated with Traumatic Brain Injury: A Systematic Review and Meta-analysis

SIGNIFICANCE

This study reports the prevalence and relative risk of photophobia in patients with traumatic brain injury (TBI).

OBJECTIVES

This study aimed to conduct a systematic review and meta-analysis to determine the prevalence and relative risk of photophobia in patients with TBI.

DATA SOURCES

Three databases were used for literature search: PubMed, EMBASE, and Cochrane Library.

STUDY APPRAISAL AND SYNTHESIS METHODS

Publications reporting the prevalence of photophobia after TBI in patients of any age were included. A series of meta-regression analyses based on a generalized linear mixed model was performed to identify potential sources of heterogeneity in the prevalence estimates.

RESULTS

Seventy-five eligible publications were identified. The prevalence of photophobia was 30.46% (95% confidence interval [CI], 20.05 to 40.88%) at 1 week after the injury. Prevalence decreased to 19.34% (95% CI, 10.40 to 28.27%) between 1 week and 1 month after TBI and to 13.51% (95% CI, 5.77 to 21.24%) between 1 and 3 months after the injury. The rapid decrease in the prevalence of photophobia in the first 3 months after a TBI injury was significant (P < .001). Three months post-TBI, the prevalence of photophobia leveled off to a near plateau with nonsignificant variability, increasing between 3 and 6 months (17.68%; 95% CI, 9.05 to 26.32%) and decreasing between 6 and 12 months since TBI (14.85%; 95% CI, 6.80 to 22.90%). Subgroup analysis of 14 publications that contained control data showed that the estimated risk ratio for photophobia was significantly higher in the TBI than in the control group during the entire 12 months after TBI.

CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

This study demonstrates that photophobia is a frequent complaint after TBI, which largely resolves for many individuals within 3 months after the injury. For some patients, however, photophobia can last up to 12 months and possibly longer. Developing an objective quantitative methodology for measuring photophobia, validating a dedicated photophobia questionnaire, and having a specific photophobia International Classification of Diseases, Tenth Revision code would greatly improve data gathering and analysis.

From the CDC: A qualitative study of middle and high school professionals' experiences and views on concussion: Identifying opportunities to support the return to school process

INTRODUCTION

Current research recommends that students returning to school after a concussion should receive a return to school plan that is tailored to their individual symptoms. School professionals play important roles in designing and implementing the supports outlined in return to school plans.

METHODS

This qualitative study explored middle and high school professionals' experiences with concussion, particularly their knowledge and perceptions of the injury and their experience with supporting students with concussion. Six focus groups were conducted with two to four school professionals per group, including two groups of teachers, two groups of school psychologists and counselors, and two groups of school nurses. Findings were coded into four categories: (a) challenges with identifying a concussion; (b) strategies for communicating with students about concussion; (c) barriers to implementing return to learn plans; and (d) establishing a collaborative school support team.

RESULTS

School professionals who participated in the focus groups were knowledgeable about concussion and the importance of helping their student recover. Participants also understood the importance of recognizing the signs and symptoms of concussion and communicating with students and parents about this injury. However, the study participants reported various challenges related to concussion identification and management, including the perceived validity of concussion symptom reporting by students. A team-based approach was mentioned across all groups as the preferred method for school-based concussion management for students.

CONCLUSION

School professionals in this study were eager to address concussion in their schools, but desire guidance on how to overcome social norms around concussion identification and reporting. In addition, there is a need for consistent use of written instructions from healthcare providers to help guide return to learn (RTL) accommodations. Practical applications: The findings from this study can help inform the integration of concussion, and other health, management plans in schools.

Ten-year trends in traumatic brain injury: a retrospective cohort study of California emergency department and hospital revisits and readmissions

OBJECTIVE

To describe visits and visit rates of adults presenting to emergency departments (EDs) with a diagnosis of traumatic brain injury (TBI). TBI is a major cause of death and disability in the USA; yet, current literature is limited because few studies examine longer-term ED revisits and hospital readmission patterns of TBI patients across a broad spectrum of injury severity, which can help inform potential unmet healthcare needs.

DESIGN

We performed a retrospective cohort study.

SETTING

We analysed non-public patient-level data from California's Office of Statewide Health Planning and Development for years 2005 to 2014.

PARTICIPANTS

We identified 1.2 million adult patients aged ≥18 years presenting to California EDs and hospitals with an index diagnosis of TBI.

PRIMARY AND SECONDARY OUTCOME MEASURES

Our main outcomes included revisits, readmissions and mortality over time. We also examined demographics, mechanism and severity of injury and disposition at discharge.

RESULTS

We found a 57.7% increase in the number of TBI ED visits, representing a 40.5% increase in TBI visit rates over the 10-year period (346-487 per 100 000 residents). During this time, there was also a 33.8% decrease in the proportion of patients admitted to the hospital. Older, publicly insured and black populations had the highest visit rates, and falls were the most common mechanism of injury (45.5% of visits). Of all patients with an index TBI visit, 40.5% of them had a revisit during the first year, with 46.7% of them seeking care at a different hospital from their initial hospital or ED visit. Additionally, of revisits within the first year, 13.4% of them resulted in hospital readmission.

CONCLUSIONS

The large proportion of patients with TBI who are discharged directly from the ED, along with the high rates of revisits and readmissions, suggest a role for an established system for follow-up, treatment and care of TBI.
