ABSTRACT Current motor vehicle crash (MVC) surveillance systems, in particular the National Automotive Sampling System (NASS), either do not contain sufficient numbers of children, or do not contain child-specific data needed to support policy and prevention efforts. The objective of this pilot study was to develop and evaluate methods that could be utilized for supplemental child-specific data collection on a sample of cases identified through the NASS-GES program. Procedures were developed to identify a sample of police accident reports (PARs) involving child occupants for supplemental collection of child-specific data via three survey modes: phone, web-based and hard-copy self administered. Contact was initiated with 650 eligible parent drivers and surveys were completed by 156 (24.0%). Response rates were highest for telephone-based surveys (41.0% of those initially contacted by phone). Surveys were completed via the web by only 6.1% of those invited to do so. Overall agreement between survey and PAR data was good to excellent. Results of this pilot study indicate that creating procedures to identify cases for supplemental child-specific data collection based on the NASS-GES system is feasible. In order to sustain a supplemental child-focused data collection system that relies on identification of cases from NASS-GES, efforts must be made to enhance contact procedures in order to optimize response rates.

    ABSTRACT: Police reports were compared to the information provided by a hospital monitoring system for children under 15 years old injured as pedestrians and bicyclists by moving motor vehicles in Orange County, California. The analysis was limited to identifying caveats in the police report database. Underreporting by police was conservatively estimated at 20% for pedestrians and 10% for bicyclists. Comparison of the pedestrian databases suggested underreporting by police of incidents involving 0-4-year-olds, nontraffic incidents, incidents in which the vehicle was backing up, and cases not involving a child crossing a street. Comparison of the bicyclist databases indicated an underreporting by police of nontraffic cases. These caveats, in part, are related to police agency reporting requirements. The police injury severity scale was found to correlate poorly with a scale based on medical diagnoses, and substantial underreporting by police of serious injuries was demonstrated. We suggest that utilization of police injury severity scales be limited to categories of fatal, injured, and not injured (when available).

    ABSTRACT: Posted speed limit and police-reported injury codes are commonly used by researchers to approximate vehicle impact and occupant injury severity. In-depth crash investigations, however, produce more precise measures of crash and injury severity: change in velocity (delta-V) for crash severity and Abbreviated Injury Scale (AIS) scores for injury severity. A comparison of data from police crash reports with that gathered by National Automotive Sampling System (NASS) investigators highlighted the inadequacy of speed limit and police injury codes as proxies for delta-V and AIS injury severity. In general, delta-V increased with speed limit and higher values of AIS were associated with higher police-coded injury severity, but there were a number of anomalies. In particular, 49% of the drivers coded by police as having incapacitating injuries actually had sustained no more than minor injuries. This overstatement of injury severity was less frequent among male (44%) and elderly (37%) drivers than among female (53%) and nonelderly (50%) drivers. Also, 79% of the investigated vehicles that crashed on roads posted at 60 mph (96 km/h) or higher experienced a delta-V less than 25 mph (40 km/h). Safety studies depending on data from only police reports to establish injury or crash severity therefore could produce erroneous results.

    ABSTRACT: Insurance claims data were combined with telephone survey and on-site crash investigation data to create the first large scale, child-focused motor vehicle crash surveillance system in the US. Novel data management and transfer techniques were used to create a nearly real-time data collection system. In the first year of this on-going project, known as Partners for Child Passenger Safety, over 1200 children < or = 15 years of age per week were identified in crashes reported to State Farm Insurance Co. from 15 states and Washington, D.C. Partners for Child Passenger Safety is similar in its design and overall objectives to National Automotive Sampling System (NASS), the only other population-based crash surveillance system currently operating in the US.
