INJURIES TO A SAMPLE OF SEATBELTED CHILDREN EVALUATED AND TREATED IN A HOSPITAL EMERGENCY ROOM

This study provides descriptions of the types of injuries sustained by a sample of children (0-14 years of age) who were using a vehicle seatbelt at the time of a motor vehicle accident and who were subsequently evaluated and treated in a hospital emergency room. Data were obtained from a hospital monitoring system established in nine emergency room facilities in a single county in California. The analysis indicates that in some cases injured seatbelted children were injured in circumstances in which the seatbelt could not have been protective, e.g., vehicle deformation into the child, flying glass, etc. The analysis of the remaining cases of seatbelted children suggests that there are significant variations in mechanisms of injury as well as injury patterns for different aged children. In many of the cases of injury observed in this sample, even though the child had been restrained in the adult seatbelt, the anatomic characteristics of the child prevented optional protection. The research provides further evidence for the necessity for utilizing specially designed restraints for children at least up to the age of 10 years.

Family, social, and cultural factors in pedestrian injuries among Hispanic children

Objectives—In an earlier population based surveillance study of pediatric injuries, the rate of Hispanic children injured as pedestrians was 63/100 000 compared with 17/100 000 for non-Hispanic white children. The present study was designed to examine the effect of family, social, and cultural factors on the rate of pedestrian injury in a population of Hispanic children in the southwestern US. Methods—A case-control study of pedestrian injuries among Hispanic children. The sample consisted of 98 children 0–14 years of age hospitalized as a result of a pedestrian injury and 144 randomly selected neighborhood controls matched to the case by city, age, gender, and ethnicity. Cases were compared with controls using conditional logistic regression; in the study design the odds ratio (OR) estimates the incidence rate ratio. Results—The following family and cultural variables were associated with an increased risk of injury: household crowding (OR=2.8, 95% confidence interval (CI) 1.1 to 7.1 for 1.01–1.5 persons per room, compared with ≤ 1.0 persons per room), one or more family moves within the past year (OR 2.2, 95% CI 1.2 to 4.1), poverty (OR 1.9, 95% CI 1.1 to 3.3), and inability of mother (OR 3.6, 95% CI 1.3 to 10) or father (OR 5.6, 95% CI 1.5 to 20) to read well. However, children in single parent households and children whose parents did not drive a car, had less education, or were of rural origin, did not have an increased rate of injury. Conclusions—These results have implications for childhood pedestrian prevention efforts for low income, non-English speaking Hispanic populations, and perhaps for other immigrant and high risk groups. Prevention programs and materials need to be not only culturally sensitive but also designed for those with limited reading skills. In addition, environmental interventions that provide more pedestrian friendly neighborhoods must be considered.

Fetal death in motor vehicle accidents

This study represents a series of cases of fetal death secondary to maternal involvement in a motor vehicle accident. During the period 1982 to 1985, nine cases were reported to the county coroners office. In approximately 50% of the cases, other injuries to the victim, excluding injuries related to the pregnancy, were minor. Evidence of fetal distress was not always apparent at the time of initial evaluation. In all cases, placental abruption was documented. The injury mechanism was generally impact with the steering wheel. At the time of the accident, none of the patients were using seat belts. These cases demonstrate that minor maternal trauma without apparent maternal distress may result in fetal demise. The data indicate the need for prolonged continuous fetal monitoring for all pregnant women involved in motor vehicle accidents.

Six-month follow-up of computerized alcohol screening, brief intervention, and referral to treatment in the emergency department

The goal of this observational study was to measure change in alcohol consumption at 6 months following emergency department computerized alcohol screening brief intervention (CASI) and referral to treatment (ED-SBIRT) with integrated brief negotiated interview (BNI) and computer-generated personal alcohol reduction plans. At-risk patients received a BNI by CASI, including personalized feedback, assessment of readiness to change, reasons for cutting down, goal setting, and a printed personal alcohol reduction plan. Alcohol use was assessed by telephone interview 6 months after CASI. Factors associated with lower alcohol consumption were examined. Of the 385 participants who completed the BNI, were consented, and enrolled, 221 subjects completed the 6-month follow-up interview. Forty-seven percent of the study sample of at-risk patients were no longer drinking over the National Institute on Alcohol Abuse and Alcoholism (NIAAA)-recommended limits. Reductions were greater for patients with Alcohol Use Disorders Identification Test (AUDIT) scores of 1 to 7. Readiness to change was a good predictor of drinking below the recommended limits. The use of computerized ED-SBIRT with integrated personalized messaging and BNI holds promise as a viable screening and intervention modality for a wide range of emergency department patients.

Comparison of motor vehicle occupant injuries in restrained and unrestrained 4- to 14-year-olds☆

This study compares injuries of restrained and unrestrained 4- to 14-year-olds in nine emergency rooms and the Coroners office in Orange County, California from 1983 to 1989. Analyses were performed separately for 4- to 9- and 10- to 14-year-olds because of differences related to the fit of the seat belt. Significantly fewer intracranial injuries and a significantly lower mean Injury Severity Score (ISS) were seen between the restrained and unrestrained for 10- to 14-year-olds in the front passenger and back seats; but for 4- to 9-year-olds in the back seat only. These same differences were noted between restrained 4- to 9-year-olds in the back compared with those in the front passenger seat. Except for 4- to 9-year-olds in the front passenger seat, our findings are consistent with similar studies of occupants of all ages. Our results suggest that lap-shoulder belts (primary restraint in front seat) may provide less protection for 4- to 9-year-olds than for 10- to 14-year-olds and adults.

Injury in children of low-income Mexican, Mexican American, and non-Hispanic white mothers in the USA : a focused ethnography

Several studies indicate that rates of serious pediatric injury are higher among Hispanics than among non-Hispanic whites in the USA. To investigate possible contributory factors, we interviewed 50 Mexican, 30 Mexican American, and 30 non-Hispanic white mothers in their own homes in the same low-income neighborhoods of Southern California. Mothers were identified via door-to-door canvassing in areas with high rates of pediatric injury. We observed household conditions and behaviors and obtained a detailed family history, including accounts of any occurrence of serious injury in a child under 5 years old, the highest-risk age group for pediatric injury. Results show that Mexican families were poorer, less educated, and lived in more hazardous and crowded conditions than did families in the other two groups. Nevertheless, they benefited from strong family bonds and a cultural tradition in which responsible older children typically supervise younger siblings. In contrast, a number of Mexican American and white mothers had been abused as children and were estranged from their own mothers; hence they lacked support and models of good parenting. There was much less self-reported smoking, drug use, and mental dysfunction among the Mexican mothers and their male partners as well as much less excessively active and/or aggressive behavior among their children. The nature of the injuries reported by the various groups seemed to reflect these differences. Appropriate interventions for each group are discussed. The study illustrates the importance of using ethnographic methods to examine the context of pediatric injury at the household level.

Cultural differences in young children's vulnerability to injuries: a risk and protection perspective.

Interview data from 100 lower income Hispanic and 50 White mothers from a nutritional service clinic extended prior research on cultural differences in the risk for unintentional pediatric injuries. Group differences were expected in reported injury incidence and in the prevalence and impact of contributing factors. As predicted, White mothers reported more injuries for a young child, and among Hispanic mothers, English language preference and use were associated with more reported injuries. Hierarchical regression analysis revealed that risky behaviors, mothers judgment about child compliance, and stressful life events were better predictors of injuries than housing quality, but among Hispanics, the impact of certain factors (e.g. child temperament) was qualified by mothers acculturation level. Stress and child temperament explained injury differences between more- and less-acculturated Hispanic families but only partially accounted for differences between White mothers and less-acculturated Hispanics. Pediatric injury risk and protective factors seemed to operate in concert with cultural processes.

Demographic risk factors for injury among Hispanic and non-Hispanic white children: an ecologic analysis

Objectives—To determine the effects of neighborhood levels of poverty, household crowding, and acculturation on the rate of injury to Hispanic and non-Hispanic white children. Setting—Orange County, California. Methods—An ecologic study design was used with census block groups as the unit of analysis. Measures of neighborhood poverty, household crowding, and acculturation were specific to each ethnic group. Poisson regression was used to calculate mutually adjusted incidence rate ratios (IRRs) corresponding to a 20% difference in census variables. Results—Among non-Hispanic white children, injury rates were more closely associated with neighborhood levels of household crowding (adjusted IRR 2.36, 95% confidence interval (CI) 1.22 to 4.57) than with neighborhood poverty (adjusted IRR 1.06, 95% CI 0.89 to 1.26). For Hispanic children, the strongest risk factors were the proportion of Hispanic adults who spoke only some English (compared with the proportion who spoke little or no English, adjusted IRR 1.26, 95% CI 1.04 to 1.53) and the proportion who were US residents for <5 years (adjusted IRR 1.20, 95% CI 1.001 to 1.43). Neighborhood levels of household crowding were not related to injury among Hispanic children (adjusted IRR 0.98, 95% CI 0.89 to 1.08), but surprisingly, neighborhood poverty was associated with lower injury rates (adjusted IRR 0.89, 95% CI 0.81 to 0.97). Conclusions—Cultural and geographic transitions, as well as socioeconomic differences, appear to contribute to differences in childhood injury rates between ethnic groups.

Feasibility of Emergency Department Bilingual Computerized Alcohol Screening, Brief Intervention, and Referral to Treatment

The purpose of this study was to assess the feasibility of utilizing a computerized alcohol screening and intervention (CASI) kiosk in an emergency department (ED). An interactive English and Spanish audiographical computer program, developed for used on a mobile computer cart, was administered to 5103 patients. Patients who screened at risk (19%) also received a fully computer-guided brief negotiated interview (BNI) and a printed personal alcohol reduction plan. A higher percentage of younger patients, and males (31% versus 16% females), screened at risk or dependent. Patient surveys indicated CASI was easy to use and over 75% did not prefer a medical professional over the computer. The ED-based bilingual computerized alcohol screening, brief intervention, and referral to treatment required little time to administer, was acceptable to patients, identified at-risk and dependent drinkers, and was able to provide personalized feedback and brief intervention.

FATALITIES TO OCCUPANTS OF CARGO AREAS OF PICKUP TRUCKS

We sought to describe the fatalities to occupants of pickup truck cargo areas and to compare the mortality of cargo area occupants to passengers in the cab. From the Fatality Analysis Reporting System (FARS) files for 1987-1996, we identified occupants of pickup trucks with at least one fatality and at least one passenger in the cargo area. Outcomes of cargo area occupants and passengers in the cab were compared using estimating equations conditional on the crash and vehicle. Thirty-four percent of deaths to cargo occupants were in noncrash events without vehicle deformation. Fifty-five percent of those who died were age 15-29 years and 79% were male. The fatality risk ratio (FRR) comparing cargo area occupants to front seat occupants was 3.0 (95% Confidence Interval [CI] = 2.7-3.4). The risk was 7.9 (95% CI = 6.2-10.1) times that of restrained front seat occupants. The FRR ranged from 92 (95% CI = 47-179) in noncrash events to 1.7 (95% CI = 1.5-1.9) in crashes with severe vehicle deformation. The FRR was 1.8 (95% CI = 1.4-2.3) for occupants of enclosed cargo areas and 3.5 (95% CI = 3.1-4.0) for occupants of open cargo areas. We conclude that passengers in cargo areas of pickup trucks have a higher risk of death than front seat occupants, especially in noncrash events, and that camper shells offer only limited protection for cargo area occupants.
