Trends in adverse effects of medical treatment in Paediatric populations in the United States: A global burden of disease study, 2000-2019.

BACKGROUND: Adverse effects of medical treatment (AEMT) pose significant risks to paediatric patients. However, the mortality trends associated with AEMT in this population have been unclear.

OBJECTIVE: We aimed to clarify the trends in the incidence, disability-adjusted life years (DALYs) and mortality rates of AEMT for children in the US from 2000 to 2019.

METHODS: Data were retrieved from the Global Burden of Disease study 2019. We estimated age-standardized incidence, DALYs and mortality rates of paediatric AEMT per 100,000 children in the US using a Bayesian meta-regression model. We also analysed incidence, DALYs and mortality in different age groups, and employed Joinpoint regression models to assess the age- and sex-specific trends.

RESULTS: The number of deaths due to AEMT in children, the number of cases, and DALYs were 105.1, 551,076 and 145,555 in 2019, decreased by 37.5%, 6% and 28% from those in 2000, respectively. Age-standardized mortality rates decreased across all age groups, while the incidence increased across all age groups with an average annual percentage change (AAPC) of 2.2% in those children <1 year and 4.5% in 5-9 years of age. The increases in DALYs over time was higher in children aged 1-4 years (AAPC: 0.51, 95% CI: 0.47, 0.62) and 5-9 years (AAPC: 0.33, 95% CI: 0.15, 0.50), with the 1-4 year age group being the highest.

CONCLUSION: The study reveals declining AEMT mortality but rising incidence and DALYs, emphasizing a disproportionate burden in <1, 1-4 and 5-9 years. To develop effective mitigation strategies, future research is warranted to identify the causes of increased AEMT in children, especially young males.
