Serious injuries and deaths of adolescent girls resulting from interpersonal violence: characteristics and trends from the United States, 1989-1998.

BACKGROUND: Little published data are available concerning the death and disability of adolescent girls resulting from interpersonal violence (adolescents are defined as those aged 12-18 years in this study). OBJECTIVES: To determine whether there were sex differences in (a) the characteristics of those who were injured or died, (b) injury severity and outcomes, and (c) injury mechanism; and to describe time trends in these differences. DESIGN: Analysis of data concerning serious injuries due to assaults, recorded in the National Pediatric Trauma Registry (from January 1, 1989, through December 31, 1998), and homicides, recorded in the Web-Based Injury Statistics and Query Reporting System database (from January 1, 1990, through December 31, 1997). SETTING: Patient data from participating pediatric trauma centers (National Pediatric Trauma Registry) in 45 states and national death certificate data (Web-Based Injury Statistics and Query Reporting System). PATIENTS: Six hundred twelve adolescent girls who were seriously injured because of an assault were compared with 2656 adolescent boys who were seriously injured because of an assault. Three thousand four hundred eighty-seven adolescent girls who died due to a homicide were compared with 17 292 adolescent boys who died due to a homicide. RESULTS: Assaulted adolescent girls were more likely to have preexisting cognitive or psychosocial impairments than were adolescent boys (odds ratio, 1.68; 95% confidence interval, 1.12-2.51). Adolescent girls trended toward more injury-related impairments at discharge from the hospital (odds ratio, 1.16; 95% confidence interval, 0.92-1.47). Adolescent girls were more likely to have been stabbed, and less likely to have been shot. Also, adolescent girls were more likely to have been injured at a home or a residence. Compared with all National Pediatric Trauma Registry admissions, assaults declined at the same rate for adolescent girls and boys. The proportion resulting from penetrating trauma declined more slowly for adolescent girls. CONCLUSIONS: Interpersonal violence causes considerable morbidity and mortality for young women. Research and interventions should be developed to respond to adolescent girls who experience interpersonal violence.

Prehospital endotracheal intubation for severe head injury in children: a reappraisal.

Controversy exists regarding the efficacy of prehospital assisted ventilation by endotracheal intubation (ETI) versus bag-valve-mask (BVM) in serious pediatric head injury. The National Pediatric Trauma Registry (NPTR-3) data set was analyzed to examine this question. NPTR-3 (n = 31,464) was queried regarding the demographics, injury mechanism, injury severity, prehospital interventions, transport mode, mortality rate, injury complications, procedure and equipment failure or complications, and functional outcome of seriously head-injured patients (n = 578) with comparable injury mechanisms and injury severity who received endotracheal intubation (ETI) (n = 479; 83%) versus those who received BVM (n = 99; 17%). Mortality rate was virtually identical between the 2 groups (ETI = 48%, BVM = 48%), although children receiving ETI were significantly older (P < .01), more often transported by helicopter (P < .01), and more often received intravenous fluid in the field (P < .05). However, injury complications affecting nearly every body system or organ (except kidney, gut, and skin) occurred less often in children receiving ETI (ETI = 58%, BVM = 71%, P < .05). Procedure and equipment failure or complications, and functional outcome, were similar between the 2 groups. Prehospital endotracheal intubation appears to offer no demonstrable survival or functional advantage when compared with prehospital bag-valve-mask for prehospital assisted ventilation in serious pediatric head injury. Injury complications appear to occur somewhat less often among patients intubated in the field.

Outcomes from television sets toppling onto toddlers.

OBJECTIVE: To assess outcomes of trauma caused by television sets falling onto children. METHODS: Retrospective review of medical charts of 183 children aged 7 years and younger hospitalized for injuries caused by falling television sets. Descriptive statistics were applied. DATA SOURCES: Phase 2 (1988-1995) and phase 3 (1995-1999) of the National Pediatric Trauma Registry. OUTCOME MEASURES: Demographics, injured body region, injury severity measured by the Injury Severity Score, length of hospital stay, admission to the intensive care unit, surgical intervention, in-hospital death rate, disability resulting from the injury, and disposition at discharge from the hospital. RESULTS: The sample population represented 0.5% of all National Pediatric Trauma Registry admissions in this age group. More than half (57.4%) of the children were boys, and more than three quarters (76.0%) were 1 to 4 years of age. In most cases (95.1%), the injury occurred at home. Most children (68.3%) sustained head injury, and 43.7% sustained injuries to multiple body regions. More than a quarter (28.4%) of the children had injuries of moderate to critical severity (Injury Severity Score, 10-75), about a third (31.1%) required admission to the intensive care unit, and 20.2% needed 1 or more surgical interventions. The average length of hospitalization was 3.3 days. Five children (2.7%) died, and 48 (26.2%) developed functional limitations, which required discharge to a rehabilitation facility in 5 cases. Most (94.0%) of the children returned to their home. The proportion of television set-related injuries increased more than 100% during the study period. CONCLUSIONS: The injuries reported are not trivial. Not only did they require hospitalization, but they also resulted in an in-hospital death rate comparable to the 2.5% rate observed in children of the same age group injured by unintentional blunt trauma, inclusive of motor vehicle traffic-related injuries. Since virtually all American children are at risk for such injury, we suggest that television set designs be modified to reduce the incidence and severity of the problem.

Child abuse and unintentional injuries: a 10-year retrospective.

OBJECTIVE: To identify differences between hospitalized children injured by child abuse and those with unintentional injuries. DESIGN: Comparative analysis of patients injured by child abuse (n = 1997) with patients injured unintentionally (n = 16 831), newborn to 4 years of age. MAIN OUTCOME MEASURES: Patient characteristics, nature and severity of injury, treatment, length of stay, survival, functional limitations, and disposition at discharge from the hospital. DATA SOURCE: Retrospective review of medical records submitted to the National Pediatric Trauma Registry between January 1, 1988, and December 31, 1997. RESULTS: During the 10-year study period, child abuse accounted for 10.6% of all blunt trauma to patients younger than 5 years. Children injured by child abuse were significantly younger (mean, 12.8 vs 25.5 months) and were more likely to have preinjury medical history (53% vs 14.1%) and retinal hemorrhages (27.8% vs 0.06%) than children with unintentional injuries. Abused children were mainly injured by battering (53%) and by shaking (10.3%); unintentionally injured children were hurt mainly by falls (58.4%) and by motor vehicle-related events (37.1%). Abused children were more likely than unintentionally injured children to sustain intracranial injury (42.2% vs 14.1%) and thoracic (12.5% vs 4.5%) and abdominal (11.4% vs 6.8%) injuries; to sustain very severe injuries (22.6% vs 6.3%); to be admitted to the intensive care unit (42.5% vs 26.9%); and to receive Child Protective Services (82.3% vs 8%) and Social Services (72.9% vs 27.6%) intervention. The mean length of stay for children who were abused was significantly longer (9.3 vs 3.8 days) and the survival to discharge from the hospital was significantly worse (87.3% vs 97.4%) than for those unintentionally injured. Among the survivors, children who were abused developed extensive functional limitations more frequently than those unintentionally injured (8.7% vs 2.7%). More than half (56.6%) of the children who were abused were discharged to custodial/foster/Child Protective Services care; most (96.1%) of the children unintentionally injured returned to their homes. CONCLUSIONS: Child abuse continues to be a serious cause of mortality and morbidity to infants and toddlers. On average, among children hospitalized for blunt trauma, those injured by abuse sustain more severe injuries, use more medical services, and have worse survival and functional outcome than children with unintentional injuries.

Functional outcome in children with multiple trauma without significant head injury.

OBJECTIVE: To assess functional outcome and describe disability at discharge in children who have had trauma without significant head injury. DESIGN: Retrospective cohort. SETTING: National Pediatric Trauma Registry, 1988-1994. PARTICIPANTS: Patients of ages 7 to 18 years with Glasgow Coma Scale (GCS) 13 to 15 without significant anatomic head inJury. RESULTS: Functional Independence Measure (FIM) at discharge was used to assess patient outcome. There were 13,649 children meeting study criteria who had sustained 34,254 injuries. Fractures constituted 30% of all injuries. As measured by FIM, 1,522 (11.2%) patients had mild disability at discharge; 1,983 (14.5%) had moderate disability. After adjustment for age and injury severity, children with lower extremity fractures were more likely to be discharged with functional limitations than those without (relative risk, 5.43; 95% confidence interval: 5.06, 5.84). Of children with moderate disability at discharge, less than 50% were referred for rehabilitation evaluation and less than 25% for physical therapy. CONCLUSION: Functional dependence is present in a large proportion of injured children, even without significant head injury. Rehabilitation and other services may be underused in this population. Further study is required to fully assess the degree and duration of disability in these patients.

Cardiopulmonary resuscitation in pediatric trauma patients: survival and functional outcome.

BACKGROUND: Although injury is the leading cause of cardiac arrests in children older than 1 year, few studies have examined the survival and functional outcome of cardiopulmonary resuscitation (CPR) in pediatric trauma patients. METHODS: A historical cohort of 957 trauma patients younger than 15 years who received CPR at the scene of injury or at the admitting hospital was constructed on the basis of the National Pediatric Trauma Registry. The rate of survival to discharge and factors related to survival were examined. Functional impairments were documented for surviving patients. RESULTS: The overall survival rate was 23.5%. With adjustment for the Injury Severity Score, the risk of fatality after CPR increased for children with systolic blood pressure below 60 mm Hg at admission (odds ratio [OR] 24.5, 95% confidence interval [CI] 8.6-69.3), for those who were comatose at admission (OR, 4.7; 95% CI, 1.9-11.6), for those with penetrating injury (OR, 4.4; 95% CI, 1.5-13.3), and for those with CPR initiated at the hospital (OR, 2.4; 95% CI, 1.5-3.9). Surviving patients stayed in hospitals for an average of 24.3 days; at discharge, 64% had at least one impairment in the functional activities of daily living. CONCLUSIONS: Survival outcome of CPR in pediatric trauma patients appears to be comparable to that reported in adults of mixed arrest causes. Future research needs to identify factors underlying the excess mortality associated with penetrating trauma.

Alcohol and other psychoactive drugs in trauma patients aged 10-14 years.

OBJECTIVE: To examine the prevalence of alcohol and/or other psychoactive drugs, such as marijuana and cocaine (AODs), involved in preteen trauma patients. METHODS: Toxicological testing results were analyzed for 1356 trauma patients aged 10-14 years recorded in the National Pediatric Trauma Registry for the years 1990-95. RESULTS: Of the 1356 patients who received toxicological screening at the time of admission, 116 (9%) were positive for AODs. AOD involvement increased with age. Patients with pre-existing mental disorders were nearly three times as likely as other patients to be AOD positive (23% v 8%, p < 0.01). AOD involvement was more prevalent in intentional injuries and in injuries that occurred at home. CONCLUSIONS: AODs in preteen trauma are of valid concern, in particular among patients with mental disorders or intentional injuries. The role of AODs in childhood injuries needs to be further examined using standard screening instruments and representative study samples.

Pediatric trauma center criteria: an outcomes analysis.

BACKGROUND/PURPOSE: Trauma centers (TC) are certified based on widely accepted criteria. These specific criteria rarely are scrutinized individually. The purpose of this study was to analyze the individual components of a pediatric trauma center for their effect on outcome. METHODS: Members of the National Pediatric Trauma Registry were queried about the following: (1) separate pediatric emergency department (ED), (2) pediatric intensive care unit (PICU), (3) pediatric intensivist as PICU director, (4) pediatric surgeon as TC director, (5) in-house attending surgeon, (6) in-house pediatric emergency physician, (7) 24-hour operating room, (8) 24-hour computed tomography (CT) scan. Outcomes analyzed included mortality, length of stay, time in ED, days in PICU, and disability. Victims were stratified based on age (<7 or > or = 7 years) and severity of injury (ISS < or = 16, 17-35, > or = 36). Results were compared using Student's t test and chi2 analysis. RESULTS: A total of 59 of 74 centers responded, 18 were dropped because of low enrollment (mean, 1.6 patients). Questions 3, 4, 6, and 7 were eliminated because of skewed data. An in-house surgeon reduced the amount of time a mildly injured patient (ISS < or = 16) spent in the ED (210 v434 minutes), as did the separate pediatric ED (333 v592 minutes) and pediatric emergency physicians (344 v 507 minutes) in younger patients (> or = 7 years). An in-house surgeon reduced the morality rate in older (> or = 7) severely injured (ISS > or = 36) patients (46.7% v 56.8%; P < .05 for all). No other differences were significant. CONCLUSIONS: In-house personnel improved efficiency for the less severely injured, and an in-house attending surgeon reduced mortality in the severely injured older patient. None of the other variables were found to have a significant impact on outcome.

Injuries to children with attention deficit hyperactivity disorder.

OBJECTIVES: To determine differences between hospital admitted injuries to children with preinjury attention deficit hyperactivity disorder (ADHD) and injuries to those with no preinjury conditions (NO). DESIGN: Comparative analysis, excluding fatalities, of ADHD patients (n = 240) to NO patients (n = 21 902), 5 through 14 years of age. OUTCOME MEASURES: Demographics, injury characteristics, length of stay, admission to the intensive care unit, surgical intervention, disability, and disposition at discharge. DATA SOURCE: Retrospective review of charts submitted by more than 70 hospitals participating in the National Pediatric Trauma Registry between October 1988 and April 1996. RESULTS: Compared with the NO children, the children with ADHD were more likely to be boys (87.9% vs 66.5%), to be injured as pedestrians (27.5% vs 18.3%) or bicyclists (17.1% vs 13.8%), and to inflict injury to themselves (1.3% vs 0.1%). They were more likely to sustain injuries to multiple body regions (57.1% vs 43%), to sustain head injuries (53% vs 41%), and to be severely injured as measured by the Injury Severity Score (12.5% vs 5.4%) and the Glasgow Coma Scale (7.5% vs 3.4%). The ADHD mean length of stay was 6.2 days versus 5.4 in the NO group. In both groups, 40% had surgery, but the ADHD children were admitted more frequently to the intensive care unit (37.1% vs 24.1%). The injury led to disability in 53% of the children with ADHD vs 48% of the NO children. Children with ADHD with any disability were twice as likely to be discharged to rehabilitation/extended care than were the NO children. CONCLUSIONS: Injured children with ADHD are more likely to sustain severe injuries than are children without ADHD. More research is needed to identify prevention efforts specifically targeted at this population.

Relationship of trauma patient volume to outcome experience: can a relationship be defined?

OBJECTIVES: Five years experience recorded in a multi-institutional pediatric trauma registry was analyzed to define the relationship between case volume and outcome as measured by mortality. METHODS: A total of 30,930 records with complete data were categorized by contributing hospital. Patients with fatal injury as indicated by an injury severity score of 75 or any abbreviated injury scale of 6 were excluded. Each center's experience was stratified by injury severity using injury severity score > or = 15 as indicative of severe injury. Centers were then classified as low volume (LV, 100-500 cases), mid volume (MV, 501-1,000 cases), or high volume (HV, > 1,000 cases). Proportion of patients with severe injury (injury severity score > 15) and mortality were compared among groups using the chi(2) test with significance accepted at p < 0.05. Using the Pediatric Risk Indicator to adjust for mortality risk, the combined hospital experience of each volume group was further analyzed to assess performance with specific levels of increasing injury severity. RESULTS: Findings demonstrated a trend of increasing mortality with increasing volume, despite a consistent proportion of severe injury. Risk adjusted mortality for each volume class indicates best outcome in the mid level group. CONCLUSIONS: Regardless of overall volume of patients encountered, there is a consistent proportion of severe injury. The increasing mortality with the most severe injuries seen in the high volume centers may reflect overdemand on resources.

Bicycle-related injuries among preschool children.

STUDY OBJECTIVE: To describe the circumstances, severity, and outcome of bicycle-related injuries among hospitalized children younger than 5 years and to compare injuries in young children (< 5 years) and older children (5 to 14 years). METHODS: We studied a case series of children (0 to 14 years) with bicycle-related injuries requiring hospital admission reported to the National Pediatric Trauma Registry (NPTR) between January 1986 and June 1996. RESULTS: Bicycle-related injuries were reported for 4,041 patients; 219 (5%) involved children younger than 5 years. Two young children and 124 older children (3%) wore bicycle helmets. Young children were less likely than older ones to be injured in the street (46% versus 81%, P < .001) and were more likely to be injured at home in the driveway or yard (39% versus 9%, P < .001). Interaction with a motor vehicle contributed to injuries in 31% of young children and 47% of older children (P < .001). Forty-five percent of young children and 56% of older children sustained head injuries (P < .002). The fractions of children in each age group with facial trauma, abdominal or thoracic injury, and fractures were similar. Pediatric Trauma Scores, Glasgow Coma Scale scores, operating room use rates, and median number of hospital days were similar for both age groups. Rehabilitation or extended care was required by 1% of young children and 2% of older children. Two deaths occurred among young children (1%); 2% of older children died. CONCLUSION: Of patients with bicycle-related injuries reported to the NPTR, a minority are young children, but they have injuries similar in severity and outcome to those of older children. Because young children sustain severe injuries, including head trauma, helmets are indicated for them, as well as for older children.

Pediatric risk indicator: an objective measurement of childhood injury severity.

INTRODUCTION: The Pediatric Risk Index (PRI) uses established measures of physiologic derangement (Pediatric Trauma Score and Glasgow Coma Scale) and anatomic severity (Injury Severity Score) to identify those patients at risk of death, impairment, or extensive resource utilization. METHODS: The PRI was evaluated by analysis of 5,345 patients entered into a multi-institutional pediatric trauma registry during 1993. PRI was calculated for each patient, and its distribution for survivors compared with those of fatalities. Analysis of this distribution identified a risk discriminant which was used to compare resulting cohorts by mortality, intensive care unit stay, and discharge impairment as measured by Functional Independence Measure. To evaluate the PRI's ability to identify unexpected outcome the records of 7,319 children injured in 1992 were then compared to the "standards" developed from the 1993 data. RESULTS: Mortality distribution analysis identified a PRI > 1 as an indication of injury related risk. For mortality, intensive care unit stay, and discharge Functional Independence Measurement, there was a statistically significant difference (chi2, p < 0.001) between the at-risk and no-risk populations. Comparison of 1992 experience demonstrated at least one potentially preventable death. CONCLUSIONS: The PRI effectively identifies injured patients at risk for dying, impairment, or extensive intensive care unit care.

Characteristics and outcomes of self inflicted pediatric injuries: the role of method of suicide attempt.

OBJECTIVE: To examine the epidemiologic characteristics and clinical outcomes of self inflicted pediatric injuries in relation to the method of suicide attempt. METHODS: Using data from the National Pediatric Trauma Registry Phase II, a comparative analysis was conducted for children under 15 years of age who were admitted from 1 October 1988 through 30 April 1996 because of self inflicted injury by firearm (n = 28), hanging (n = 38), or jumping from heights (n = 21). RESULTS: Of the 87 cases under study, 90% occurred at home, and 86% occurred between noon and midnight, with a peak in early evening (between 6 pm and 7 pm)-More than one quarter (29%) had preexisting mental disorders, such as disturbance of conduct and depression. Toxicological tests were conducted on admission on 40 (46%) of the patients; 20% tested positive for alcohol or other illicit drugs. The method of suicide attempt was associated with gender and age of the patients: 75% of the firearm cases and 82% of the hanging cases were boys compared with 29% of the jumping cases (p < 0.01); 79% of the hanging cases were aged 13 years or younger compared with 39% of the firearm cases and 48% of the jumping cases (p < 0.01). The mean injury severity score was 18.6 for the firearm cases and 16.3 for the hanging cases, significantly greater than 8.5 for the jumping cases (p < 0.02). Reflecting the differences in injury severity, firearm cases and hanging cases were more likely than jumping cases to be sent to intensive care units or operating rooms from emergency departments, and to develop complications during hospitalization. The case fatality rate was 50% for the firearm cases, 32% for the hanging cases, and 5% for the jumping cases (p < 0.01). On average, these patients stayed in hospitals for 11 days and 52% of those who were alive at discharge had at least one impairment in communication, cognition, or self care functions. CONCLUSION: Boys and older children tend to use more lethal methods in suicide attempts. Even in this age group, suicide attempts often involve psychiatric disorders and acute abuse of alcohol or other illicit drugs. Firearms are associated with significantly increased risk of inhospital fatality. The clinical outcomes of self inflicted injuries appear to be worse than other injuries treated in the same trauma centers.

Blunt hepatic injury in adolescents: age makes a difference.

This analysis of mortality from blunt hepatic injury was performed to define outcome in the adolescent age group in relation to that recorded for children and adults. Children (age 0-10 years) were selected from a multi-institutional trauma registry, adults (age > or = 21 years) from the registry of a Level I trauma center, and adolescents (age 11-20 years) from both. Groups were compared by injury frequency, proportion of severe hepatic injuries (code 864.03 or 864.04 in the International Classification of Diseases, Adapted for Use in the United States 9-CM), immediate laparotomy, mortality, and cause of death. Children had the lowest proportion of severe injury and overall mortality. Torso trauma was the primary cause of death in only three children. Adolescent injury patterns were similar to those of adults in the proportion of severe visceral disruption and incidence of fatal torso trauma. Immediate laparotomy was employed almost twice as commonly in adults as in adolescents. The 64 per cent of adolescents who did not undergo laparotomy had a lower mortality than those who did. Conversely, the 36 per cent of adults without exploration had a significantly higher mortality, which usually occurred before laparotomy could be initiated. Increasing hepatic injury severity brought increasing mortality; however, the cause of death differed with age. Although the incidence of severe liver injury did not differ between adolescents and adults, management and outcome did. These data indicate that individualized management based on overall patient status remains the best approach to care of these injuries.

Factors associated with the intent of firearm-related injuries in pediatric trauma patients.

OBJECTIVE: To examine the characteristics of unintentional and assaultive firearm-related pediatric injuries treated in trauma centers. DESIGN: Comparative analysis of patients 14 years or younger who were admitted to the trauma centers because of unintentional firearm-related injuries (n = 292) vs assaultive firearm-related injuries (n = 457). SETTING: Sixty-eight trauma centers or children's hospitals in the continental United States and Canada that reported data to the National Pediatric Trauma Registry from January 1, 1990, through December 31, 1994. MAIN OUTCOME MEASURES: Frequency distributions of firearm-related injuries in relation to intent and injury circumstances, odds ratios (ORs) on the intent of injury being assaultive, injury severity scales, and in-hospital fatality rates. RESULTS: The frequency of unintentional firearm-related injuries rose in the afternoons peaking between 4 and 5 PM; they predominantly occurred at home (89%). Assaultive firearm-related injuries peaked sharply between 8 and 9 PM and usually occurred on roads or in other public places (63%). About 3 times as many boys as girls were harmed in firearm-related injuries. Given a firearm-related injury resulting in admission to a trauma center, the adjusted OR of it being assaultive was 2.8 (95% confidence interval [CI], 1.6-4.6) if the victim was a girl, 4.9 (95% CI, 3.1-7.8) if the shooting occurred at night, 2.6 (95% CI, 1.6-4.2) if the shooting occurred on a weekday, and 21.1 (95% CI, 9.1-49.4) if the shooting occurred on a road. Injury patterns and severity were similar between patients with unintentional and assaultive injuries. Overall, 19% of the patients sustained head injuries, which contributed to 90% of the in-hospital deaths. CONCLUSIONS: Marked differences in injury circumstances exist between unintentional and assaultive firearm-related injuries among children. The late afternoon hours when many children have come home from school but their parents may still be working have the highest frequency of unintentional firearm-related injuries. The evening peak of assaultive injuries may be related to drug-related and gang-related violence. While it is important to reduce the access of firearms to children, school-based extracurricular and community-based social services should be considered in developing intervention programs.

Death from pelvic fracture: children are different.

This study compares outcome from pelvic fractures in children with that of adults. Data for 23,700 children registered in the National Pediatric Trauma Registry (NPTR) were compared with those of 10,720 adults recorded over 5 years in the registry of our level I trauma center. Patients were categorized by open versus closed fracture and by fracture type as defined by a modification of the Key and Conwell system. Outcome was evaluated by mortality rate and incidence of fracture-induced fatal exsanguination. The 722 pelvic fractures recorded in the NPTR represent 3% of the population and is half the frequency represented by the 532 adults evaluated (P < .001). The overall mortality rate was 5% for children and 17% for adults. Two children died of fracture-related exsanguination; there were 18 such deaths among the adults. Pelvic ring disruption was encountered more commonly among adults, and was associated with a significantly higher mortality rate. Patients with initial hemodynamic instability were more likely to die, although children less so than adults. The authors conclude that children do not die of pelvic fracture-associated hemorrhage as often as adults. Massive blood loss in the child occurs most commonly from solid visceral injury rather than from pelvic vascular disruption.

Children who are shot: a 30-year experience.

Three data sets describe the pattern of gunshot injuries to children from 1960 to 1993: The Harlem Hospital pediatric trauma registry (HHPTR), the northern Manhattan injury surveillance system (NMISS) a population-based study, and the National Pediatric Trauma Registry (NPTR). A small case-control study compares the characteristics of injured children with a control group. Before 1970 gunshot injuries to Harlem children were rare. In 1971 an initial rise in pediatric gunshot admissions occurred, and by 1988 pediatric gunshot injuries at Harlem Hospital had peaked at 33. Population-based data through NMISS showed that the gunshot rate for Central Harlem children 10 to 16 years of age rose from 64.6 per 100,000 in 1986 to 267.6 per 100,000 in 1987, a 400% increase. The case fatality for children admitted to Harlem Hospital (1960 to 1993) was 3%, usually because of brain injury, but the majority of deaths occurred before hospitalization. During the same period, felony drug arrests in Harlem increased by 163%. The neighboring South Bronx experienced the same increase in gunshot wound admissions and felony arrests from 1986 to 1993. The NPTR showed a similar injury pattern for other communities in the United States. In a case-control analysis. Harlem adolescents who had sustained gunshot wounds were more likely to have dropped out of school, to have lived in a household without a biological parent, to have experienced parental death, and to have known of a relative or friend who had been shot than community adolescents treated for other medical or surgical problems.(ABSTRACT TRUNCATED AT 250 WORDS)

Factors related to the presence of head injury in bicycle-related pediatric trauma patients.

Using data from the National Pediatric Trauma Registry, this study examined the characteristics of bicycle-related head injury, factors related to the presence of head injury, and different outcomes of head injury up to the time of discharge. Of the 2,333 patients ages 0 to 14 years who were admitted to trauma centers because of bicycle-related injury during 1989 through 1992, more than one-half (54%) sustained head injury, predominantly concussions and skull fractures. With adjustment for age, sex, and motor vehicle involvement, children who had pre-existing mental disorders, who did not wear a helmet at the time of injury, or who were injured on roads had a significantly increased likelihood of sustaining head injuries. Patients with a head injury were four times as likely as patients with no head injury to be treated in intensive care units, and were almost twice as likely to develop complications. Head injury was associated with an increased risk of inhospital fatality and high prevalence rates of communication and behavior impairments at discharge. Although it is urgent to increase helmet use substantially by child bicyclists, special attention should be paid to high-risk groups, such as children with mental disorders and children who are likely to ride in traffic.
