Assessing Neglect in Pediatric Environmental Deaths: A Survey of Manner of Death Determinations

ABSTRACT

There are 4 common types of environmental pediatric deaths that may involve various degrees of neglect: hyperthermia, ingestion, drownings, and unsafe infant sleep practices. Because the circumstances surrounding each are disparate, there is no set of standards by which these factors may be weighed and interpreted. Given the same facts, the manner of death certification may differ depending upon training/experience and/or local practice.To assess certification variations, 147 board-certified forensic pathologists were surveyed for the choice of manner in scenarios with different degrees of negligence intent. In addition to evaluating certification consistency, the survey examined whether certain factors affected the choice. The results demonstrated strong consistency in certain scenarios and widely disparate certifications in others.Medical examiner/coroner certifications are administrative decisions for vital statistical purposes. The manner of death reflects an evidence-based conclusion, but because it is ultimately an opinion, determinations may vary. Based on the survey, some certification criteria were identified (ie, intent, child age, and knowingly placing a child in an environment with a reasonable risk of harm). Using these criteria may improve consistency, but it is unreasonable to expect 100% concordance. Understanding the certificate's role helps to place the manner in the proper legal and public health contexts.

Alcohol Consumption and 15 Causes of Fatal Injuries: A Systematic Review and Meta-Analysis

INTRODUCTION

The proportion of fatal nontraffic injuries that involve high levels of alcohol use or alcohol intoxication was assessed by cause of injury to generate alcohol-attributable fractions. Updated alcohol-attributable fractions can contribute to improved estimates of the public health impact of excessive alcohol use.

METHODS

Peer-reviewed and gray literature for 1995-2019 on 15 causes of fatal nontraffic injuries in the U.S., Canada, or Mexico were systematically reviewed, and state data systems were queried for available estimates of fatalities with recorded blood alcohol concentration levels and proportions of decedents with blood alcohol concentrations ≥0.10 g/dL by cause of injury. For each injury cause, alcohol-attributable fractions across studies were synthesized by meta-analysis of single proportions using generalized linear mixed models.

RESULTS

In total, 60 published studies and 40 additional population-level data points from 6 state data systems were included. The meta-analyzed alcohol-attributable fractions by cause of injury are as follows: air-space transport (0.03), aspiration (0.24), child maltreatment (0.09), drowning (0.31), fall injuries (0.37), fire injuries (0.34), firearm injuries (0.24), homicide (0.29), hypothermia (0.29), motor vehicle nontraffic crashes (0.42), occupational and machine injuries (0.08), other road vehicle crashes (railroad trespasser injuries) (0.63), poisoning (not alcohol) (0.20), suicide (0.21), and water transport (0.27), yielding an overall median alcohol-attributable fraction of 0.27.

DISCUSSION

Excessive alcohol use is associated with substantial proportions of violent and nonviolent injury deaths. These findings can improve the data used for estimating alcohol-attributable injury deaths and inform the planning and implementation of evidence-based strategies (e.g., increasing alcohol taxes, regulating alcohol outlet density) to prevent them.

Race, urban context, and Russian roulette: findings from the National Violent Death Reporting System, 2003-2006

Previous work on Russian roulette has focused on data from large cities. It is unclear if the epidemiological patterns based on large cities will replicate for the nation as a whole, and if the influence of minority status will be moderated by urban context. The present investigation fills these gaps by providing descriptive epidemiological data on Russian roulette for 17 states, and testing a hypothesis on urbanism as a moderator of the race-Russian roulette relationship. Data were taken from the National Violent Death Reporting System (2003-2006). They refer to 71 Russian roulette cases and a matched control group of 284 males who committed suicide by a gunshot wound to the head. Russian roulette suicides were more apt to be of minority status, younger, had a lower incidence of mental health problems, and were more likely to be utilizing alcohol than the controls. Differentiating the sample into larger and smaller urban areas, it was found that the risk of Russian roulette for African Americans was higher in larger urban areas. Epidemiological patterns in previous research on large city samples are largely replicated. The moderating influence of urban context is related to differential opportunity structures for risk-taking behavior.
