Variation of drugs involved in acute drug toxicity presentations based on age and sex an epidemiological approach based on European emergency departments.
To analyse the relative percentage of acute recreational drug toxicity emergency department (ED) presentations involving the main drug groups according to age and sex and investigate different patterns based on sex and age strata. We analysed all patients with acute recreational drug toxicity included by the Euro-DEN Plus dataset (22 EDs in 14 European countries) between October 2013 and December 2016 (39 months). Drugs were grouped as opioids, cocaine, cannabis, amphetamines, gamma-hydroxybutyrate (GHB), hallucinogens, new psychoactive substances (NPS), benzodiazepines and ketamine. Descriptive data by age and sex are presented and compared among agesex categories and among drug families. Of 17,371 patients were included during the 39-month period, 17,198 (99.0%) had taken at least one of the investigated drugs (median age 31 years 23.9% female ethanol co-ingestion recorded in 41.5%, unknown in 31.2% multiple drug use in 37.9%). Opioids (in 31.4% of patients) and amphetamines (23.3%) were the most frequently involved and hallucinogens (1.9%) and ketamine (1.7%) the least. Overall, female patients were younger than males, both in the whole cohort (median age 29 vs. 32 years Differences in the drugs involved in acute drug toxicity presentations according to age and sex may be relevant for developing drug-prevention and education programs for some particular subgroups of the population based on the increased risk of adverse events in specific sex andor age strata.
