Medication Errors With Pediatric Liquid Acetaminophen After Standardization of Concentration and Packaging Improvements.
OBJECTIVE
To assess the impact of the 2011 changes in pediatric single-ingredient liquid acetaminophen product packaging and standardization of the acetaminophen concentration (160 mg/5 mL) on poison control center exposures due to medication errors.


METHODS
National Poison Data System (NPDS) data from January 1, 2007, through December 31, 2016, were used to identify medication error exposures involving single-ingredient liquid acetaminophen in children younger than 12 years of age. Surveys were conducted through 6 regional poison control centers to obtain additional information on a subset of exposures.


RESULTS
The annual frequency of NPDS exposures due to medication errors with single-ingredient liquid acetaminophen products was 8260 ± 670 exposures/year during 2007-2011. Children <2 years of age accounted for 66% of exposures. The overall rate of exposures fell to 6669 ± 662 during 2012-2016 (19% decrease; P = .005). Four percent of exposures led to health care facility referrals. Caregivers involved with exposures in children <2 years of age cited health professionals as the source of dosing information in only 69% of cases despite the absence of specific dosing directions for these children on product labels.


CONCLUSIONS
Implementation of a single concentration for pediatric liquid acetaminophen products and packaging changes were associated with a decrease in medication errors reported to poison control centers. Medication errors are particularly problematic for children <2 years of age, for whom there are no specific labeled dosing instructions. Improved efforts to provide caregivers with dosing instructions for these children are encouraged.
