Patient and injury characteristics in abusive abdominal injuries.

OBJECTIVE: To identify patient and injury characteristics associated with suspected child abuse in the setting of blunt abdominal trauma. PATIENTS: We extracted from the National Pediatric Trauma Registry phases 2 and 3 (October 1995 to April 2001; N = 106,135) all cases of blunt abdominal injury, excluding motor vehicle injuries, in patients aged 0 to 4 years. MAIN OUTCOME MEASURES: Independent variables included age, mortality, nutritional status, and injury type. The dependent variable was suspected child abuse. RESULTS: Six hundred sixty-four cases were analyzed. The median age of patients was 2.6 years; 11.4% were undernourished. The 3 most common mechanisms of injury were suspected child abuse (40.5%), fall (36.6%), and struck-not child abuse (9.7%). Hepatic injury (46.1%) was the most common intra-abdominal injury, followed by splenic (26%), hollow viscous (17.9%), and pancreatic (8.6%) injuries. Eighty-four percent of deaths were related to suspected child abuse. There was a greater proportion of children with suspected child abuse in every patient and injury characteristics studied than all other mechanisms combined. In a regression model including age, undernourishment, pancreatic injury, hollow viscous injury, traumatic brain injury, and mortality, all variables were significantly associated with suspected abuse. Hollow viscous injury had the highest odds ratio (OR, 9.5; confidence limits, 5.7, 15.8), whereas traumatic brain injury had the lowest (OR, 3.6; confidence limits, 2.4, 5.6). CONCLUSIONS: Young children with severe pancreatic or hollow viscous injuries or severe abdominal injuries in the context of either brain injury or undernourishment should be evaluated for the possibility that these injuries resulted from abuse. Increasing the awareness of the possibility of child abuse associated with a set of injury characteristics may allow for more consistent and complete medical evaluation.

Management of blunt pediatric hepatic and splenic injury: similar process, different outcome.

Though nonoperative management of stable children with blunt solid organ injury has been shown to be effective, we hypothesize that hepatic injuries represent a higher mortality risk than splenic injuries and that combination hepatosplenic injury is a marker of even greater mortality potential. A multi-institutional pediatric trauma registry was queried for all children with blunt injuries to the liver (H) or spleen (S), excluding those with severe brain injury. Incidence and mortality of H, S, and all combinations of H/S were compared. The mortality rate for patients with H was significantly higher (2.5%) than in patients with S (0.7%), and the overall mortality of H/S (8.6%) was significantly higher than both. Furthermore, the mortality of H/S injuries was associated with increasing severity of either the hepatic or splenic injury. In childhood injury, H and S occur with almost equal frequency but with different mortality, and H/S is less common but associated with increased mortality.

Blunt abdominal injury in the young pediatric patient: child abuse and patient outcomes.

This study sought to evaluate injury causes and patient outcomes in young children with abdominal injuries. Cases of blunt abdominal injury (N = 927) to children ages 0 to 4 years were extracted from the National Pediatric Trauma Registry. Measures included hospital utilization (days hospitalized, intensive care unit use, and surgery) and patient outcome (in-hospital fatality, discharge to rehabilitation facility, home rehabilitation, and home nursing). The three most common mechanisms of abdominal injury were motor vehicles (61.27%), child abuse (15.75%), and falls (13.59%). Hospital utilization was higher in patients with multisystem injuries. Patient outcomes were more severe in abused children or those with concomitant central nervous system (CNS) injury; these were the only variables independently associated with increased mortality in this sample. Pediatric abdominal trauma leads to intense use of hospital resources and a high risk of in-hospital mortality. Child abuse, compared to falls, is independently associated with a 6-fold increase in in-hospital mortality.

Water safety: age-specific changes in knowledge and attitudes following a school-based intervention.

OBJECTIVES: To explore whether an intervention during mandatory schooling can lead to age-specific changes in water safety knowledge and attitudes. METHODS: Age-specific questionnaires were distributed to 202 kindergarten and grade one pupils, 220 elementary school pupils and 337 pupils attending the first three high school grades in Greater Athens. The information was used to design an educational package that was subsequently presented to pupils of the same grades and similar socio-demographic profiles attending different schools in the same area. One month later, a post-exposure evaluation was conducted using the initial questionnaires, in which 115, 205 and 321 pupils from the respective grade categories provided their responses. In order to compare the performance of pupils exposed to the educational intervention with that of pupils who participated only in the initial assessment, mean differences in scores measuring overall knowledge and attitudes were estimated within each of the three grade groups adjusting for age, gender, sibship size, maternal education and swimming knowledge. RESULTS: Among kindergarten and grade one pupils, those who received the intervention scored significantly higher for knowledge (17.40%, 95% CI 6.41% to 28.39%) and attitudes (23.64%, 95% CI 4.48% to 42.79%). Among elementary school pupils the gains in knowledge were less evident (14.58%, 95% CI -3.05% to 32.21%)) and almost null in attitudes (5.64%, 95% CI -11.47% to 22.77%). Further advancement of age showed no improvement in knowledge (-0.15%, 95% CI -5.30% to 4.99%) and a minimal, insignificant increase in attitudes (6.32%, 95% CI -1.87% to 14.52%) among exposed high school pupils. CONCLUSION: The school-based intervention resulted in considerable positive changes in knowledge and attitudes among very young pupils. Elementary schooling seems to provide meagre opportunities to simply improve knowledge. Alternative/complementary approaches should be sought in any attempt to modify behavior.

Functional status after childhood traumatic brain injury.

BACKGROUND: Identification of children after traumatic brain injury (TBI) likely to have functional deficits at trauma center discharge will facilitate care. METHODS: Two logistic regression models were derived from data on 4,439 children after TBI 7 to 14 years old enrolled in the National Pediatric Trauma Registry between 1994 and 2001 to predict physical and cognitive disabilities. RESULTS: Children with open or multiple fractures or closed fractures or injured by motor vehicles were 8.2, 3.5, or 2.5 times more likely, respectively, than those without those circumstances to have discharge physical disabilities. Likelihood of cognitive impairment was increased by factors of 3.2 and 5.8 in children obtunded or comatose on arrival. Preexisting cognitive deficits, injury severity, and intubation predicted physical and cognitive disabilities. The C statistic was 0.862 for the motor model and 0.860 for the cognitive model. CONCLUSION: Predicting the likelihood of morbidity after acute management of childhood TBI can provide information pertinent to providing effective care.

Outcomes in children and young adults who are hospitalized for firearms-related injuries.

OBJECTIVES: To compare outcomes by intent of nonfatal firearms-related injuries in a hospitalized population, newborn to 19 years of age, and estimate the national incidence of ensuing disability. METHODS: Descriptive statistics and comparative analysis using chi(2), odds ratio, and t test were applied to data from the National Pediatric Trauma Registry (NPTR) and the National Electronic Injury Surveillance System of the US Consumer Product Safety Commission. Demographics, preinjury medical history, scene of injury, primary body part injured, severity of injury, utilization of resources, short-term and long-term disability, medical cause of disability, and disposition at discharge were studied. RESULTS: NPTR unintentional (n = 268) and assault-related firearms-related injuries (n = 506) were compared. In both groups, the majority of patients were male (80%). Compared with the unintentionally injured, the assaulted children were older and more frequently black (59.3% vs 32.5%). Approximately 17% in both groups had a preinjury history of medical/psychosocial problems. Unintentional injuries occurred mainly in private dwellings (75.7%), and assaults occurred in public places/street (53.8%). In both groups, injuries to multiple body regions were prevalent, and a substantial proportion sustained injuries of serious to critical level. Most children were transported by ambulance, but a significant proportion in the unintentional group were transported by helicopter. The rate of admission to the intensive care unit was approximately 40% for both groups. The unintentionally injured had a higher rate of surgical intervention (66.8% vs 50.8%) and stayed in the hospital longer than the assaulted ones (median: 5 days vs 3 days). Almost half of the children in both groups were discharged with disability, and approximately 87% returned to their home. Applying the NPTR disability rate to National Electronic Injury Surveillance System estimates of hospitalization suggests that approximately 3200 children nationwide develop disability from firearms-related injuries annually. CONCLUSIONS: Nonfatal firearms-related injuries in a pediatric population are associated with a high use of medical resources and lasting disability. Public policies should be developed and implemented to reduce the occurrence of these catastrophic events.

The incidence of recreational genitourinary and abdominal injuries in the Western New York pediatric population.

PURPOSE: We estimate the incidence of recreation related pediatric abdominal, testis and kidney injuries. MATERIALS AND METHODS: Trauma registry data at the regional pediatric trauma center for 1993 to 2000 were analyzed for recreational injuries. The data were divided into the 3 age groups of 5 to 11, 12 to 14 and 15 to 18 years. The recreation, and site and severity of injury were cross referenced. Injury incidence was calculated using United States census data. RESULTS: Of 4,921 children 34 boys and 2 girls (0.73%) had a genitourinary or abdominal injury due to recreation. Kidney injuries were the most common (44.4%), followed by spleen (36.1%) and liver (19.5%). No testicle injuries were reported. Skiing was the most common cause of injury (22.2%). Hockey, football, snowboarding, sledding and bicycling accounted for 83% of all injuries. There were no injuries related to basketball and soccer. The 12 to 14-year-old group had 50% of the injuries. Records were available for 15 kidney injuries, of which 11 were on the left side, 1 was bilateral, 3 required transfusion and 1 required nephrectomy. Injury grades were I in 2 cases, II in 5, III in 4, IV in 3 and V in 1. Kidney and spleen injury incidence due to recreation per year per million children was 6.9 and 5.6, respectively. CONCLUSIONS: Kidney injuries were more common than spleen injuries. Skiing, sledding and snowboarding accounted for more injuries than team sports. Testicle injuries were not seen and are rare. Basketball and soccer caused no injuries. Middle school-age children appear to be at greatest risk.

Kidney and testicle injuries in team and individual sports: data from the national pediatric trauma registry.

PURPOSE: We define the risk of kidney or testicle injury in children who play contact sports. MATERIALS AND METHODS: National Pediatric Trauma Registry data from 50 United States pediatric trauma centers for 1990 to 1999 were analyzed. The data were from age groups 5 to 11, 12 to 14 and 15 to 18 years. Major abdominal injuries, injuries due to team and individual contact sports, and the site of injury were examined. RESULTS: Of the 81,923 cases 5,439 were sports related. Abdominal injuries occurred in 459 patients (0.56%), and were due to contact sports in 191. Team sports were involved in 184 cases, including football in 44%, hockey in 19%, baseball in 15%, soccer in 12% and basketball in 6%. Abdominal injury rate by age was 16% for 5 to 11-year olds, 42% for 12 to 14-year-olds and 42% for 15 to 18-year-olds. Most common was splenic injury at 50% of cases, kidney injuries occurred in 22% and no testicle injuries were reported. Football accounted for the most kidney injuries (62%). Kidney injuries were more common among older teenagers. No injuries led to nephrectomy. CONCLUSIONS: Abdominal injuries are rare in children who play team and individual contact sports. No testicular injuries were reported. Kidneys are most at risk in football. Splenic injuries are most common overall, although the risk to kidney and spleen is equal in basketball. No kidneys were reported as lost. These data should help families and schools when assessing risk to genitourinary organs during these activities.

Pediatric trauma caused by personal watercraft: a ten-year retrospective.

BACKGROUND/PURPOSE: Evidence indicates that young adults are at significant risk for powered personal watercraft (PWC)-related injuries. This article examines the nature of PWC injuries sustained in the pediatric population over a 10-year period. METHODS: Retrospective analysis was conducted of trauma registry charts on 66 pediatric patients, aged 5 to 19 years, hospitalized for PWC-related injuries between 1990 and 1999. The keywords PWC and Jet Ski were used to extract anonymous data from the National Pediatric Trauma Registry, which then were analyzed using descriptive statistics. RESULTS: The most common mechanism of injury was a collision with another PWC, a boat, or a fixed object (70%). A total of 55.1% of all the injury diagnoses involved the head, face, and/or neck, and 72.7% of the injuries occurred to the operator of the PWC. A total of 83.3% of the patients required at least 1 surgical procedure, and 42.2% required admission to the intensive care unit. Four children (6.1%) died, and 28 (42.4%) of the children had disabilities as a consequence of the injury. CONCLUSIONS: Operation of PWCs can result in severe injures, death, and long-term disability in the pediatric population. Possible safety recommendations include minimum age regulations, operator training, operating regulations, design improvements, and required helmet use.

Pediatric trauma is very much a surgical disease.

OBJECTIVE: The evolution of nonoperative management of certain solid visceral injuries has stimulated speculation that management of the severely injured child is no longer a surgical exercise. The authors hypothesized that the incidence of injuries that require surgical evaluation is disproportionately high in children at risk of death or disability from significant injury. METHODS: National Pediatric Trauma Registry data were queried for all patients with ICDA-9-CM diagnoses requiring at least surgical evaluation. Selected diagnoses included CNS: 800 to 804, 850 to 854; thoracoabdominal: 860 to 870; pelvic fracture: 808; and acute vascular disruption: 900 to 904. Operative intervention was identified by ICDA-9-CM operative codes less than 60 and selected operative orthopedic codes between 79.8 and 84.4. At-risk patients were identified as those with at least one of the following: Glasgow Coma Scale score less than 15, Glasgow Coma Scale motor score less than 6, initial systolic blood pressure less than 90, or Injury Severity Scale score more than 10. The incidence of a surgical diagnosis in at-risk children was compared to the incidence in the population with no identifiable risk. Within the population undergoing surgical evaluation, resource utilization, as reflected by operative intervention and ICU days, and outcome, as reflected by mortality, were compared between the at-risk group and the group with no identifiable risk. RESULTS: From 1987 to 2000, 87,424 records were complete enough for analysis. Of those, 48,687 (55.6%) patients sustained at least one injury requiring a surgical evaluation and 28,645 (32.7%) children were determined to be at risk. Mortality for at-risk children was 5.8% versus 0.02% for those with no identifiable risk. Of the children at risk, 24,706 (86.2%) had at least one injury requiring a surgical evaluation. Of the 58,779 children with no risk, 23,981 (40.8%) also had at least one injury requiring a surgical evaluation. Operative intervention for surgical injuries was required in 20.5% of cases (n = 10,015). Of these, 5,562 (56%) were at-risk children, and they had a mortality rate of 11.5%. Of the children not at risk, 4,453 required operative care, and they had a mortality of 0.1%. At-risk children undergoing surgery required an average of 5.02 days of ICU care compared to 1.2 for cases performed on children without risk. CONCLUSIONS: These data clearly demonstrate the primacy of surgical pathology as the major determinant of outcome in pediatric injury. Operative intervention and the option of timely operative care remain major components of clinical management of children with injuries that pose a significant risk of morbidity or mortality.
