Trends in hospital admission related to poisoning by, narcotics and psychodysleptics and poisoning by antiepileptic, sedative-hypnotic, and antiparkinsonism drugs in England and Wales between April 1999 and April 2020: An ecological study

Abstract

BackgroundThis study aimed to investigate the trend of hospital admissions related to poisoning by narcotics and psychodysleptics and poisoning by antiepileptic, sedative-hypnotic, and antiparkinsonism drugs in England and Wales between April 1999 and April 2020. MethodsAn observational ecological study were conducted using data from the Hospital Episode Statistics database in England and the Patient Episode Database for Wales. The rate of hospital admissions with 95% confidence intervals (CIs) was calculated by dividing the number of episodes of poisoning by narcotics and psychodysleptics related admission and poisoning by antiepileptic, sedative-hypnotic, and antiparkinsonism drugs-related admission by the mid-year population from the Office for National Statistics. All analyses were conducted using SPSS version 27. ResultsThe total annual number of hospital admissions for narcotics and psychodysfunctionals poisonings increased by 1.40-fold [from 15.70 (95% CI 15.36–16.04) in 1999 to 37.64 (95% CI 37.15–38.13) in 2020 per 100,000 people, p < 0.01]. However, the overall annual number of poisonings by antiepileptic, sedative-hypnotic and antiparkinsonism drugs hospital admissions for various reasons decreased by 12.8% [from 33.55 (95% CI 33.05–34.04) in 1999 to 29.26 (95% CI 28.82–29.69) in 2020 per 100,000 persons, p < 0.05]. Poisoning by other opioids (53.2%), heroin (15.1%), and other synthetic narcotics (13.3%) were the most common reasons for narcotic and psychodysfunctional poisoning. While poisoning by benzodiazepines (54.2%) and poisoning: other antiepileptic and sedative-hypnotic drugs (30.7%) were the most common hospital admission reasons for poisoning by antiepileptic, sedative-hypnotic, and antiparkinsonism. ConclusionPoisoning by narcotics have increased in England and Wales over the study period, however, poisoning by antiepileptic, sedative-hypnotic, and antiparkinsonism drugs in England and Wales were relatively stable during the same period. Future initiatives and awareness programs to prevent harmful use and drug poisoning by narcotics, sedative-hypnotic and other medications are needed.
