Abstract

Background

Cannabis exposures in children have risen sharply in recent years, resulting in increased hospital visits and admission to pediatric intensive care units (PICUs). The intent of this study was to describe the proportion of pediatric patients admitted to the PICU after unintentional cannabis ingestion that received critical care interventions (CCIs) along with describing trends over time in hospitalization, admission to the PICU, and clinical effects and treatments outside of the PICU.

Methods

This was a retrospective database study utilizing the National Poison Data System (NPDS) from 1/1/2000 to 12/31/2020. Children 6 months to 12 years of age with single substance cannabis exposures were included.

Results

A total of 12,882 cases were included. There was an increase in the proportion of cases seen in a hospital over time from 43.8% in 2000 to 54.6% in 2020 (range 29.1–62.6%). In patients seen in a HCF, the proportion admitted to the PICU was 9.5% in 2000 and 14% in 2020 (range: 5.6–29.0%). The 875 (6.8%) children admitted to the PICU were analyzed for the primary outcome. CCIs were performed in 69/875 (7.9%) cases that were admitted to the PICU. The most common CCIs in the PICU were intubation and sedation, 4.9 and 3.7%, respectively.

Conclusions

Unintentional pediatric cannabis exposures are associated with clinically significant effects, including respiratory depression, hypotension, and bradycardia, but fewer than 5% of exposures were treated with CCIs, like intubation or vasopressors, in patients admitted to the PICU. Further work should assess specific reasons for admission to the PICU.

Acknowledgments

The American Association of Poison Control Centers (AAPCC) maintains the National Poison Data System (NPDS), which houses de-identified case records of self-reported information collected from callers during exposure management and poison information calls managed by the country’s poison control centers (PCCs). NPDS data do not reflect the entire universe of exposures to a particular substance as additional exposures may go unreported to PCCs; accordingly, NPDS data should not be construed to represent the complete incidence of U.S. exposures to any substance(s). Exposures do not necessarily represent a poisoning or overdose and AAPCC is not able to completely verify the accuracy of every report. Findings based on NPDS data do not necessarily reflect the opinions of AAPCC.
