Long-term Parental and Family Adaptation Following Pediatric Brain Injury

Predicting family burden following childhood traumatic brain injury: a cumulative risk approach

OBJECTIVE

To examine the utility of a cumulative risk index (CRI) in predicting the family burden of injury (FBI) over time in families of children with traumatic brain injury (TBI).

PARTICIPANTS

One hundred eight children with severe or moderate TBI and their families participated in the study.

MEASURES

The measures used in the study include the Socioeconomic Composite Index, Life Stressors and Social Resources Inventory--Adult Form, Vineland Adaptive Behavior Scales, Child Behavior Checklist, Children's Depression Inventory, McMaster Family Assessment Device, Brief Symptom Inventory, and Family Burden of Injury Interview. In addition, information on injury-related risk was obtained via medical charts.

METHODS

Participants were assessed immediately, 6, and 12 months postinjury and at a 4-year extended follow-up.

RESULTS

Risk variables were dichotomized (ie, high- or low-risk) and summed to create a CRI for each child. The CRI predicted the FBI at all assessments, even after accounting for autocorrelations across repeated assessments. Path coefficients between the outcome measures at each time point were significant, as were all path coefficients from the CRI to family burden at each time point. In addition, all fit indices were above the recommended guidelines, and the chi statistic indicated a good fit to the data.

CONCLUSIONS

The current study provides initial support for the utility of a CRI (ie, an index of accumulated risk factors) in predicting family outcomes over time for children with TBI. The time period immediately after injury best predicts the future levels of FBI; however, cumulative risk continues to influence the change across successive postinjury assessments. These results suggest that clinical interventions could be proactive or preventive by intervening with identified "at-risk" subgroups immediately following injury.

Neural correlates of verbal associative memory and mnemonic strategy use following childhood traumatic brain injury

Children with traumatic brain injury (TBI) often experience memory deficits, although the nature, functional implication, and recovery trajectory of such difficulties are poorly understood. The present fMRI study examined the neural activation patterns in a group of young children who sustained moderate TBI in early childhood (n = 7), and a group of healthy control children (n = 13) during a verbal paired associate learning (PAL) task that promoted the use of two mnemonic strategies differing in efficacy. The children with TBI demonstrated intact memory performance and were able to successfully utilize the mnemonic strategies. However, the TBI group also demonstrated altered brain activation patterns during the task compared to the control children. These findings suggest early childhood TBI may alter activation within the network of brain regions supporting associative memory even in children who show good behavioral performance.

Family burden after traumatic brain injury in children

OBJECTIVE

Traumatic brain injury has a substantial impact on caregivers. This study describes the burden experienced by caregivers of children with traumatic brain injury and examines the relationship between child functioning and family burden during the first year after injury.

PATIENTS AND METHODS

Children aged 5 to 15 years hospitalized for traumatic brain injury at 4 participating trauma centers were eligible. Caregivers completed baseline and 3- and 12-month telephone interviews measuring the child's health-related quality of life using the Pediatric Quality of Life Inventory. The emotional impact scale of the Child Health Questionnaire was used to identify caregivers with substantial distress, including general worry or interference with family routine. Caregiver perceptions of whether health care needs were met or unmet and days missed from work were also measured.

RESULTS

A total of 330 subjects enrolled; follow-up was conducted with 312 at 3 months and 288 at 12 months. Most subjects were white (68%) and male (69%). Abnormal Pediatric Quality of Life Inventory subscores were related to substantial caregiver burden (either general worry or interference in routine). These abnormalities were reported by >75% of patients at 3 months and persisted to 1 year in some patients. Parental perception of unmet health care needs was strongly related to family burden outcomes, with up to 69% of this subset of parents reporting substantial worry, and nearly one quarter reporting interference with daily routine/concentration 1 year after injury. Child dysfunction predicted parental burden at 3 and 12 months. Burden was greater when health care need was unmet. Abnormalities on the Pediatric Quality of Life Inventory predicted the amount of work missed by parents, especially in the presence of unmet needs.

CONCLUSIONS

Caregivers are more likely to report family burden problems when child functioning is poorer and health care needs are unmet. Improved identification and provision of services is a potentially modifiable factor that may decrease family burden after pediatric traumatic brain injury.

Traumatic brain injuries in early childhood: initial impact on the family

OBJECTIVE

The purpose of this study was to examine factors that affect parental burden and distress during the first few months following a traumatic brain injury (TBI) in young children.

METHODS

Participants were consecutively enrolled children ages 3 through 6 years with either a TBI (n = 89; 21 severe, 22 moderate, and 45 complicated mild) or orthopedic injury (OI; n = 119) requiring hospitalization. During the post-acute period, parents provided information regarding the preinjury family environment and current caregiver functioning and injury-related burden.

RESULTS

Compared with parents of young children with OI, parents of children with TBI reported greater overall caregiver burden and greater burden related to the injury. Parents of children with severe TBI also reported more stress with spouses and siblings and higher levels of parental depression and global distress relative to the OI comparison group. Parents of 5- to 6-year-old children reported significantly higher levels of both injury-related burden and distress than parents of 3- to 4-year-old children. Parents of children with mild TBI based on the Glasgow Coma Scale (GCS) who also had positive neuroimaging findings reported greater injury-related burden than parents of children with moderate TBI. Parents reported using a variety of coping strategies, with higher levels of denial and disengagement corresponding with greater injury-related burden and distress.

CONCLUSIONS

Consistent with previous research on family adaptation to TBI in school-age children, chronic life stresses and interpersonal resources accounted for significant variance in measures of acute injury-related burden and parental distress in parents of younger children, although differences were small. TBI severity defined by GCS scores alone may not be sufficient to identify families at risk of increased burden. Findings suggest that services aimed at facilitating family adjustment following TBI in young children may need to consider a broader definition of risk factors when identifying families who would benefit from interventions.

Lessons learned: the effect of prior technology use on Web-based interventions

This study examined the role of regular prior technology use in treatment response to an online family problem-solving (OFPS) intervention and an Internet resource intervention (IRI) for pediatric traumatic brain injury (TBI). Participants were 150 individuals in 40 families of children with TBI randomly assigned to OFPS intervention or an IRI. All families received free computers and Internet access to TBI resources. OFPS families received Web-based sessions and therapist-guided synchronous videoconferences focusing on problem solving, communication skills, and behavior management. All participants completed measures of depression, anxiety, and computer usage. OFPS participants rated treatment satisfaction, therapeutic alliance, and Web site and technology comfort. With the OFPS intervention, depression and anxiety improved significantly more among technology using parents (n = 14) than nontechnology users (n = 6). Technology users reported increasing comfort with technology over time, and this change was predictive of depression at followup. Satisfaction and ease-of-use ratings did not differ by technology usage. Lack of regular prior home computer usage and nonadherence were predictive of anxiety at followup. The IRI was not globally effective. However, controlling for prior depression, age, and technology at work, there was a significant effect of technology at home for depression. Families with technology experience at home (n = 11) reported significantly greater improvements in depression than families without prior technology experience at home (n = 8). Although Web-based OFPS was effective in improving caregiver functioning, individuals with limited computer experience may benefit less from an online intervention due to increased nonadherence.

Neighborhood characteristics and outcomes after traumatic brain injury

OBJECTIVE

To determine the extent to which characteristics of a person's neighborhood contribute to outcomes after traumatic brain injury (TBI).

DESIGN

Prospective cohort.

SETTING

A specialized brain injury unit providing acute rehabilitation care.

PARTICIPANTS

A consecutive sample of participants (N=200) in the Traumatic Brain Injury Model Systems (TBIMS) longitudinal study: 100 participants were 2 years postinjury, and 100 participants were 5 years postinjury.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

U.S. Census Bureau block group descriptors of economic and social characteristics and initial and follow-up data from the TBIMS national dataset including the Glasgow Outcome Scale-Extended (GOS-E) and Satisfaction With Life Scale (SWLS).

RESULTS

Economic and social characteristics of a person's neighborhood accounted for additional variance in outcomes beyond what could be accounted for by individual characteristics, including demographic, premorbid, and injury-related measures; concurrent measures of functioning; and the persons's perception of environmental influences. Individual characteristics predicted a substantial proportion of the variance in the GOS-E (69%); neighborhood characteristics contributed an additional 1.5%. Individual characteristics predicted 33.3% of the variance in SWLS, with neighborhood characteristics accounting for an additional 6.9%.

CONCLUSIONS

For both outcomes, a small but important proportion of the variance accounted for by neighborhood indices was unique to these environmental influences and was not accounted for by individual indices, including concurrent measures of functioning and the individual's perception of environmental influences. Further investigations of how neighborhood factors affect outcomes after TBI are warranted.

Pediatric traumatic brain injury: an update of research to understand and improve outcomes

PURPOSE OF REVIEW

Traumatic brain injury is the leading cause of death in the pediatric population. The purpose of this review is to highlight recent contributions in evaluation, management, and predictors of outcome in pediatric traumatic brain injury.

RECENT FINDINGS

Advances have been made in defining the critical Glasgow Coma Score for predicting poor outcome and in developing the Relative Head Injury Severity Score, which can assess severity of traumatic brain injury from administrative datasets. More information regarding the radiation risks of head computed tomography imaging and guidelines for the appropriate use of imaging have recently been evaluated. Important steps have also been taken to reduce secondary brain injury through the use of hypertonic saline and induced hypothermia. There continues to be long-term neurodevelopmental deficits among survivors and new tools to assess these deficits have been developed and tested. Finally, increased investigation into understanding the impact of minority race and socioeconomic status has on outcome following traumatic brain injury has determined the existence of disturbing disparities.

SUMMARY

Traumatic brain injury is the leading cause of mortality and is a major public health issue in the pediatric population. There have been many recent contributions in the diagnosis, treatment, and long-term morbidity of traumatic brain injury. Ongoing work is needed to improve outcomes of traumatic brain injury equitably for all patients.

Executive functioning in the first year after pediatric traumatic brain injury

BACKGROUND AND OBJECTIVE

Children with traumatic brain injuries often show impaired executive function (the ability to carry out goal-directed behavior). The Behavior Rating Inventory of Executive Function, a caregiver-report questionnaire, measures executive function in everyday activities. In this study, our goal was to use the Behavior Rating Inventory of Executive Function to document changes in children's executive function in the first year after traumatic brain injury and identify child, family, and injury variables associated with greater dysfunction. We predicted that children with traumatic brain injury would have more executive dysfunction than children hospitalized for orthopedic fractures and that more severe traumatic brain injury would predict greater dysfunction. Children's premorbid functioning and family characteristics were expected to moderate their executive function.

PATIENTS AND METHODS

Caregivers of children aged 5 to 15 years (330 mild-to-severe traumatic brain injury, 103 control orthopedic fractures) enrolled onto a longitudinal study of executive function. Caregivers completed the Behavior Rating Inventory of Executive Function by telephone at baseline (obtained retrospectively) and 3 months and 1 year after the injury.

RESULTS

Traumatic brain injury groups and controls showed no baseline differences in Behavior Rating Inventory of Executive Function scores. Three months after the injury, children with traumatic brain injury had more dysfunction than controls on the Global Executive Composite. One year after injury, all traumatic brain injury groups differed from the controls on the Behavioral Regulation Index, Metacognition Index, and Global Executive Composite. The working memory scale was the only scale to discriminate between the control group and all 3 traumatic brain injury severity groups at both 3 and 12 months after injury. Executive-function ratings remained stable from 3 to 12 months after injury. Across time points, preexisting learning/behavior problems, lower respondent education, and poor family functioning predicted greater Global Executive Composite dysfunction.

CONCLUSIONS

Between 18% and 38% of the children with traumatic brain injury had significant executive dysfunction in the first year after injury, with greater dysfunction reported for children with more severe traumatic brain injury. Our findings support previous reports that preinjury learning and behavior problems, limited family resources, and poor family functioning adversely affect executive function. These results suggest a need for more systematic screening for executive dysfunction after traumatic brain injury to increase recognition of cognitive disability and improve access to appropriate services.

Measuring children's health-related quality of life after trauma

Consideration of children's health-related quality of life (HRQOL) after injury is a critical aspect of outcome in assessing the effectiveness of trauma care. Numerous instruments are available today for measuring the HRQOL of injured children. HRQOL instruments reflect the subjective perspective of the impact an injury or disease has on a child's physical, emotional, and social well being. Most studies to date have examined children's HRQOL during the first year postinjury, relatively little is known about children's long-term HRQOL after trauma. Most trauma outcome studies have included children with heterogeneous injuries so the impact of specific injuries on HRQOL outcomes has not been well established. The majority of outcome studies have focused on injured children who have been hospitalized, however the research should be extended to the emergency department because a large proportion of injured children are treated and released from there. In addition to documenting recovery, investigators should use HRQOL instruments to evaluate the quality of care we offer injured children and their families. Rigorously conducted HRQOL assessment will provide valuable information that we can use to successfully optimize children's recovery after trauma.
