A ten-year retrospective California Poison Control System experience with water bead exposures: a growing problem

Area of Science:

• Pediatric Toxicology
• Consumer Product Safety

Background:

• Water beads, popular superabsorbent toys, pose an ingestion risk leading to intestinal obstruction.
• Limited data exists on healthcare utilization and management of water bead exposures beyond case reports.

Purpose of the Study:

• To evaluate healthcare utilization and clinical outcomes of water bead exposures reported to a large poison control system.

Main Methods:

• A 10-year retrospective review (2014-2023) of the California Poison Control System database.
• Identification of water bead exposures via product codes and keyword searches.
• Statistical analysis of demographic and clinical data linked to a composite endpoint of medical intervention.

Main Results:

• 2,280 water bead exposures were recorded, with a significant increase from 2014 to 2023.
• 8.1% of patients reached the composite endpoint, with symptoms like abdominal pain significantly associated with increased risk.
• Children with behavioral issues, including autism, showed a significant association with reaching the composite outcome.

Conclusions:

• Water bead exposures have surged despite prevention efforts, straining healthcare resources.
• While procedural interventions are rare, symptomatic cases warrant thorough evaluation.
• Enhanced regulations, public awareness, and education are crucial to mitigate risks associated with water bead ingestion.
