Pediatric Providers’ Self-Reported Knowledge, Practices, and Attitudes About Concussion

OBJECTIVE: To determine the self-reported practices and attitudes surrounding concussion diagnosis and management in a single, large pediatric care network. METHODS: A cross-sectional survey was distributed to pediatric primary care and emergency medicine providers in a single, large pediatric care network. For all survey participants, practices and attitudes about concussion diagnosis and treatment were queried. RESULTS: There were 145 responses from 276 eligible providers, resulting in a 53% response rate, of which 91% (95% confidence interval [CI]: 86%–95%) had cared for at least 1 concussion patient in the previous 3 months. A Likert scale from 1 “not a barrier” to 5 “significant barrier” was used to assess providers’ barriers to educating families about the diagnosis of concussion. Providers selected 4 or 5 on the scale for the following barriers and frequencies: inadequate training to educate 16% (95% CI: 11%–23%), inadequate time to educate 15% (95% CI: 12%–24%), and not my role to educate 1% (95% CI: 0.4%–5%). Ninety-six percent (95% CI: 91%–98%) of providers without a provider decision support tool (such as a clinical pathway or protocol) specific to concussion, and 100% (95% CI: 94%–100%) of providers without discharge instructions specific to concussion believed these resources would be helpful. CONCLUSIONS: Although pediatric primary care and emergency medicine providers regularly care for concussion patients, they may not have adequate training or infrastructure to systematically diagnose and manage these patients. Specific provider education, decision support tools, and patient information could help enhance and standardize concussion management.

Characteristics of Prolonged Concussion Recovery in a Pediatric Subspecialty Referral Population

OBJECTIVE To identify pre-existing characteristics associated with prolonged recovery from concussion in a sample of patients referred to a pediatric sports medicine clinic. STUDY DESIGN This was a retrospective, exploratory cohort study of 247 patients age 5-18 years with concussion referred to a tertiary pediatric hospital-affiliated sports medicine clinic from July 1, 2010, through December 31, 2011. A random sample of all eligible patient visits (3740) was chosen for further review and abstraction. Statistical comparisons between subsets of patients were conducted using exact χ(2) tests, logistic regression, quantile regression, and Kaplan-Meier survival curves. RESULTS The median time until returning to school part-time was 12 days (IQR 6-21); until returning to school full-time without accommodations was 35 days (IQR 11-105); until becoming symptom-free was 64 days (IQR 18-119); and until being fully cleared to return to sports was 75 days (IQR 30-153). Furthermore, 73% of all patients were symptomatic for >4 weeks, 73% were prescribed some form of school accommodation, and 61% reported a decline in grades. Characteristics associated with a prolonged recovery included a history of depression or anxiety; an initial complaint of dizziness; abnormal convergence or symptom provocation following oculomotor examination on physical examination; and history of prior concussion. CONCLUSIONS Pediatric and adolescent patients with concussion may experience cognitive and emotional morbidity that can last for several months following injury. Clinicians should consider specific pre-existing characteristics and presenting symptoms that may be associated with a more complicated recovery for concussion patients.

Point of Health Care Entry for Youth With Concussion Within a Large Pediatric Care Network

IMPORTANCE Previous epidemiologic research on concussions has primarily been limited to patient populations presenting to sport concussion clinics or to emergency departments (EDs) and to those high school age or older. By examining concussion visits across an entire pediatric health care network, a better estimate of the scope of the problem can be obtained. OBJECTIVE To comprehensively describe point of entry for children with concussion, overall and by relevant factors including age, sex, race/ethnicity, and payor, to quantify where children initially seek care for this injury. DESIGN, SETTING, AND PARTICIPANTS In this descriptive epidemiologic study, data were collected from primary care, specialty care, ED, urgent care, and inpatient settings. The initial concussion-related visit was selected and variation in the initial health care location (primary care, specialty care, ED, or hospital) was examined in relation to relevant variables. All patients aged 0 to 17 years who received their primary care from The Childrens Hospital of Philadelphias (CHOP) network and had 1 or more in-person clinical visits for concussion in the CHOP unified electronic health record (EHR) system (July 1, 2010, to June 30, 2014) were selected. MAIN OUTCOMES AND MEASURES Frequency of initial concussion visits at each type of health care location. Concussion visits in the EHR were defined based on International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes indicative of concussion. RESULTS A total of 8083 patients were included (median age, 13 years; interquartile range, 10-15 years). Overall, 81.9% (95% CI, 81.1%-82.8%; n = 6624) had their first visit at CHOP within primary care, 5.2% (95% CI, 4.7%-5.7%; n = 418) within specialty care, and 11.7% (95% CI, 11.0%-12.4%; n = 947) within the ED. Health care entry varied by age: 52% (191/368) of children aged 0 to 4 years entered CHOP via the ED, whereas more than three-quarters of those aged 5 to 17 years entered via primary care (5-11 years: 1995/2492; 12-14 years: 2415/2820; and 15-17 years: 2056/2403). Insurance status also influenced the pattern of health care use, with more Medicaid patients using the ED for concussion care (478/1290 Medicaid patients [37%] used the ED vs 435/6652 private patients [7%] and 34/141 self-pay patients [24%]). CONCLUSIONS AND RELEVANCE The findings suggest estimates of concussion incidence based solely on ED visits underestimate the burden of injury, highlight the importance of the primary care setting in concussion care management, and demonstrate the potential for EHR systems to advance research in this area.

Cognitive Rest and School-Based Recommendations Following Pediatric Concussion The Need for Primary Care Support Tools

Objectives. (1) Assess pediatric primary care providers’ understanding of cognitive rest for concussion and (2) describe their concussion management practices. Methods. This study included (1) a survey of general pediatric providers and (2) an electronic medical record (EMR) review of children 5 to 18 years old treated for concussion from September 1, 2010, to May 31, 2011. The survey asked about treatment recommendations for concussion, and results were coded to identify cognitive rest recommendations. The EMR review included the following: injury details, medical evaluation, and recommendations for resuming school and sports/recreation. Results. In all, 89 of 201 providers responded to the survey, and 52 of the 84 clinicians who included comments about concussion management mentioned cognitive rest (62%, 95% confidence interval [CI] = 51%-72%). Of the 91 EMRs reviewed for patients’ first visits following the concussion, only 10 (11%, 95% CI = 6%-19%) included written cognitive rest recommendations. Conclusions. Although the majority of pediatric providers identified cognitive rest as important in pediatric concussion management, few provided written recommendations in the EMR.

Vestibular Deficits following Youth Concussion.

OBJECTIVE To characterize the prevalence and recovery of pediatric patients with concussion who manifest clinical vestibular deficits and to describe the correlation of these deficits with neurocognitive function, based on computerized neurocognitive testing, in a sample of pediatric patients with concussion. METHODS This was a retrospective cohort study of patients ages 5-18 years with concussion referred to a tertiary pediatric hospital-affiliated sports medicine clinic from July 1, 2010 to December 31, 2011. A random sample of all eligible patient visits was obtained, and all related visits for those patients were reviewed. RESULTS A total of 247 patients were chosen from 3740 eligible visits for detailed review and abstraction; 81% showed a vestibular abnormality on initial clinical examination. Those patients with vestibular signs on the initial examination took a significantly longer time to return to school (median 59 days vs 6 days, P=.001) or to be fully cleared (median 106 days vs 29 days, P=.001). They additionally scored more poorly on initial computerized neurocognitive testing, and it took longer for them to recover from neurocognitive deficits. Those patients with 3 or more previous concussions had a greater prevalence of vestibular deficits, and it took longer for those deficits to resolve. CONCLUSION Vestibular deficits in children and adolescents with a history of concussion are highly prevalent. These deficits appear to be associated with extended recovery times and poorer performance on neurocognitive testing. Further studies evaluating the effectiveness of vestibular therapy on improving such deficits are warranted.

The Association of Overweight and Ankle Injuries in Children

OBJECTIVES Overweight children are at increased risk for many medical problems. Trauma is the leading etiology of childhood morbidity and mortality. No previous study has evaluated the association between overweight and acute ankle injuries in children. We hypothesized that being overweight is associated with an increased risk of ankle injury in children. METHODS We conducted a case-control study in an urban pediatric emergency department. Subjects aged 5 to 19 years were recruited from June 2005 through July 2006. Children with acute ankle trauma were enrolled as cases. A convenience sample of children with a chief complaint of fever, headache, or sore throat was enrolled as controls. Demographic information and anthropometric measurements were obtained. Age- and gender-specific body mass index percentiles (BMI-Ps) were calculated using pediatric norms. Multivariate unconditional logistic regression was used to assess the relationship between overweight and ankle injury, adjusting for demographic variables. Through medical records, we obtained demographic information and weight, but not height, of all cases that were not enrolled. This allowed us to conduct a sensitivity analysis in which we combined the enrolled and nonenrolled cases into a single case group and made increasingly more unlikely assumptions about the height percentiles of the nonenrolled cases. RESULTS One hundred eighty cases and 180 controls were enrolled in the study. We observed a significant association between overweight and ankle injury (multivariate-adjusted odds ratio 3.26, 95% confidence interval, 1.86-5.72; P value for trend <.0001). Although this result may be an overestimate of the magnitude of the association due to a possible bias in the selection of cases, sensitivity analysis demonstrated the robustness of the statistical significance of the finding. CONCLUSIONS Overweight children may be at increased risk of ankle injury.

Usefulness of computerized pediatric motor vehicle safety discharge instructions

OBJECTIVES To determine whether providing child motor vehicle safety recommendations on computerized discharge instructions (CDIs) were useful to parents and modified their use of child-restraint devices (CRDs). METHODS The subjects were guardians of children seen in an urban pediatric emergency department (ED). An intervention group was given computerized ED discharge instructions that included the National Highway Traffic Safety Administration recommendations for motor vehicle CRDs. A control group was given CDIs without the recommendations. All subjects were subsequently called within four days of the ED visit and asked questions about their knowledge and use of CRDs. They also were queried if the recommendations affected their knowledge or changed their behavior. RESULTS There were 52 subjects in the control group and 58 in the intervention group. Fifty-seven percent of the intervention group remembered reading a safety tip (p < 0.001, 95% confidence interval [CI] = 0.32 to 0.62), and 82% of that subset correctly identified it pertaining to motor vehicle safety. Forty-five percent (n = 33) of those who remembered the safety recommendation in the intervention group supported it being educational (p = 0.067, 95% CI = 0.28 to 0.64). Ten percent of the subjects in the intervention group said the CDIs changed their behavior regarding buckling-up their child, compared with 0% of the control group (p = 0.473, 95% CI = 0.05 to 0.32). CONCLUSIONS Including CRD information on CDIs is a convenient method of educating guardians of patients about motor vehicle safety in a pediatric ED setting. The data suggest that parents find it educational and a smaller subgroup change their behaviors after receiving them.

Emergency department evaluation and management of blunt abdominal trauma in children

Purpose of review To discuss the emergency department evaluation and management of children with blunt abdominal trauma. The review will focus on both the clinical data that can help reduce the use of computed tomography in the evaluation of patients with blunt abdominal trauma and the evidence for the increased use of nonoperative management of patients with blunt abdominal trauma. Recent findings We will examine the recent literature focusing on the utility of physical examination, laboratory data and imaging (both ultrasonography and computed tomography) in detecting intraabdominal injury. Summary Recent research suggests that physical examination in combination with bedside ultrasonography may identify children at risk for intraabdominal injury. Screening laboratory data appears to be less sensitive to detect these injuries, but is useful in selected patients. Nonoperative management is appropriate in a majority of cases. Further research is needed to determine which low-risk patients with abdominal trauma can be managed with minimal or no exposure to radiation in the computed tomography scanner.

Physical Disability After Injury-Related Inpatient Rehabilitation in Children

OBJECTIVE: To determine the residual physical disability after inpatient rehabilitation for children 7 to 18 years old with traumatic injuries. METHODS: This was a retrospective cohort study of patients aged 7 to 18 years who underwent inpatient rehabilitation for traumatic injuries from 2002 to 2011. Patients were identified from the Uniform Data System for Medical Rehabilitation. Injuries were captured by using standardized Medicare Inpatient Rehabilitation Facility Patient Assessment Instrument codes. Functional outcome was measured with the Functional Independence Measure (FIM) instrument. A validated, categorical grading system of the FIM motor items was used, consisting of clinically relevant levels of physical achievement from grade 1 (need for total assistance) to grade 7 (completely independent for self-care and mobility). RESULTS: A total of 13 798 injured children underwent inpatient rehabilitation across 523 facilities during the 10-year period. After a mean 3-week length of stay, functional limitations were reduced, but children still tended to have residual physical disabilities (median admission grade: 1; median discharge grade: 4). Children with spinal cord injuries, either alone or in combination with other injuries, had lower functional grade at discharge, longer lengths of stay, and more comorbidities at discharge than those with traumatic brain injuries, burns, and multiple injuries (P < .0001 for all comparisons). CONCLUSIONS: Children had very severe physical disability on admission to inpatient rehabilitation for traumatic injuries, and those with spinal cord injuries had persistent disability at discharge. These traumatic events during critical stages of development may result in a substantial care burden over the child’s lifespan.

Protection of children restrained in child safety seats in side impact crashes.

BACKGROUND The performance of child restraint systems (CRS) in side impact motor vehicle crashes has been under study due to the injury and fatality burden of these events. Although previous research has quantified injury risk or described injured body regions, safety advances require an understanding of injury causation. Therefore, the objective was to delineate injury causation scenarios for CRS-restrained children in side impacts and document probable contact points in the vehicle interior. METHODS Two in-depth crash investigation databases, the Crash Injury Research and Engineering Network and the Partners for Child Passenger Safety Study, were queried for rear-seated, CRS-restrained children in side impact crashes who sustained Abbreviated Injury Scale 2+ injury. These cases were reviewed by a multidisciplinary team of physicians and engineers to describe injury patterns, injury causation, and vehicle components that contributed to the injuries. RESULTS Forty-one occupants (average age, 2.6 years) met the inclusion criteria. Twenty-four were near side to the crash, 7 were far side, and 10 were center seated. The most common injuries were to the skull and brain with an increasing proportion of skull fracture as age increased. Head and spine injuries without evidence of head contact were rare but present. All thoracic injuries were lung contusions and no rib fractures occurred. Near-side head and face contacts points were along the rear vertical plane of the window and the horizontal plane of the window sill. Head and face contact points for center- and far-side occupants were along the edges of the front seat back and front seat head restraint. CONCLUSIONS Head injuries are the target for injury prevention for children in CRS in side impact crashes. Most of these injuries are due to the contact; for near-side occupants, contact with the CRS structure and the door interior, for far- or center-seated occupants, contact with the front seat back. These data are useful in developing both educational and technological interventions to reduce the burden of injury to these children.
