A demographic comparison and characterization of pediatric poisoning before and after the emergence of COVID-19.

BACKGROUND

To compare relative rates of pediatric poisoning before and after COVID-19, including by demographic and urban-rural status, and by agent identified, using data from one university healthcare system and children's hospital.

METHODS

Using retrospective, cross sectional design from deidentified healthcare claims data, we extracted all encounters with the ICD-10-CM for Poisoning by, Adverse effects of, and Underdosing of drugs, medicants and biological substances (T36-T50) and grouped the encounters as those after state mandates regulating activity came into effect (Post-COVID-19 (3/17/2020-3/18/2021)) Pre-COVID-19 (3/18/2019-3/17/2020). We then compared poisoning agent, age at the time of the encounter, recorded sex, race, ethnicity, rural/urban residence, and visit type using Mann-Whitney U test, chi-square test of association, incidence rates and incident rate ratios between the time periods.

FINDINGS: The sample included 1608 unique patients 0-17 years of age and 4216 encounters. We also identified IRRs >1 in nearly every demographic subgroup with the exception of Non-Hispanic Blacks. The comparison of specific drugs or medicants identified a significant decrease in poisoning by Systemic antibiotics (T36); but an increase in Hormones and their synthetic substitutes and antagonists (T38), Non opioid analgesics antipyretic and antirheumatic (T39), Psychotropic Drugs (T39) and Systemic and hematologic agents (T45).

CONCLUSION

This study identifies pediatric subgroups highly affected by pediatric poisoning during the time-period immediately after the identification of COVID-19 and characterizes the drugs commonly associated with poisonings.

APPLICATION TO PRACTICE: With a further understanding nursing has the potential to impact pediatric poisoning in the inpatient, outpatient and public health setting.
