Trends in poisoning deaths in England and Wales show shifts in substances used for suicide and drug abuse. Data limitations highlight the need for poison-specific mortality tracking.

Area of Science:

  • Toxicology and Public Health
  • Mortality Statistics Analysis
  • Epidemiology of Substance Abuse

Background:

  • Accurate recording of acute poisoning and substance abuse deaths is challenging using standard International Classification of Diseases (ICD) codes, which focus on underlying causes like suicide or drug dependence.
  • Historical data from England and Wales reveal significant changes in the types of poisons involved in suicides over 35 years, influenced by substance availability.
  • While poisoning suicides have declined, overall suicide rates, particularly in males, remain stable due to increases in non-poisoning related suicides.

Purpose of the Study:

  • To analyze trends in fatal poisoning deaths in England and Wales.
  • To identify changes in substances contributing to suicidal poisoning and drug abuse-related deaths.
  • To evaluate the adequacy of ICD-derived data for tracking poisoning deaths and advocate for a poisons-oriented approach.

Main Methods:

  • Analysis of mortality statistics for England and Wales over several decades.
  • Examination of trends in suicidal poisoning, drug abuse-related deaths, and volatile substance abuse (VSA)-related deaths.
  • Comparison of poisoning data with overall suicide trends and demographic differences.

Main Results:

  • Suicidal poisoning trends show shifts, with notable changes in carbon monoxide and barbiturate use.
  • Drug abuse-related fatal poisonings, primarily heroin and methadone, increased in the 1990s, though methadone deaths are now decreasing.
  • Volatile substance abuse (VSA)-related deaths, mainly from fuel gases, peaked in the early 1990s and are now seen in older age groups, with a male predominance in both drug abuse and VSA deaths.

Conclusions:

  • ICD-derived mortality data are insufficient for adequately capturing poisoning-specific trends, particularly for drug abuse and VSA.
  • A 'poisons-oriented' approach to data collection and analysis is necessary for a comprehensive understanding of fatal poisoning.
  • Understanding these trends is crucial for public health interventions and substance abuse prevention strategies.
