In nine pediatric dosing trials, more than 80% of parents made more than one medication dosing error, according to a study by H. Shonna Yin, MD, and associates. Misunderstandings about how to accurately choose the right dosing tools as well as confusion related to units of measure contribute to most errors. Matching dosing tools more closely with prescribed dose volumes, as well as using pictograms, can greatly reduce the number of pediatric medication errors, the researchers noted.
The study shows that 83.5% of parents made at least one dosing error (overdosing was present in 12.1% of errors), and 29.3% of parents made at least one large error in administering their children’s medicine. Parents who received text-only instructions or milliliter/teaspoon labels made more large errors. The biggest influence on errors resulted from providing tools more closely matched to the recommended dose measurements.
The researchers conducted a randomized controlled experiment in three pediatric clinics. Each site’s institutional review board approved the study. An average of 491 parents of children older than 8 years were randomly assigned to one of four groups, and given labels and dosing tools that varied in label instruction format and units. Each parent measured nine doses of liquid medicine in a random order, using three different tools.
Parents in group 1 received text and pictogram dosing instructions with milliliter-only labels and tools. They had decreased odds of making a dosing error compared with parents who received milliliter/teaspoon labels and tools without pictographic instructions in groups 2 and 4, and had lower odds of making large dosing errors compared with group 3, whose participants received text-only instructions (Pediatrics. 2017 June 27. doi: 10.1542/peds.2016-3237).
“Our findings support the use of a specific algorithm to help health care providers and pharmacists determine which dosing tool is most optimal to provide to parents,” said Dr. Yin. “We found that pictograms were associated with statistically significant reductions in large overdosing errors, with a trend for reduction in any error.”
