Evaluation of consumer medical information and oral liquid measuring devices accompanying pediatric prescriptions.
OBJECTIVE
The aim of this study was to assess supplementary materials accompanying 2 commonly prescribed pediatric medications, including the following: 1) readability and layout characteristics of pharmacy-generated consumer medical information(CMI); and 2) types and features of oral liquid measuring devices(OLMDs) provided.


METHODS
We filled the same two prescriptions (prednisolone and amoxicillin) at 20 pharmacies (national grocery store chain [n = 1], regional grocery store chains [n = 4], national pharmacy chains [n = 3], national superstore chains [n = 3], and independently owned [n = 9]) across three states (Colorado,Georgia, and Tennessee). We evaluated readability, using both the Flesch-Kincaid (FK) formula and McLaughlin's Simplified Measure of Gobbledygook (SMOG), and text point size of pharmacy-generated CMI. We also assessed whether an OLMD(oral syringe, dropper, or cylindrical spoon) was included with each prescription and recorded the largest marked dose (in mL).


RESULTS
Three pharmacies did not provide any type of CMI for either medication. Therefore, CMI was reviewed for 34 prescriptions. Reading grade levels of CMI averaged 9.6 1.9 (range, 5.3-11.7) using the FK and 11.2 2.6 (range, 6-14) based on the SMOG. Average text font size of CMI was 9.8 1.9 (range, 6-12). Although 32 (80%) prescriptions included an OLMD (oral syringe [n = 20], cylindrical spoon [n = 7], and dropper [n = 5]), close to one third (31.3%) would require multiple measurements to attain prescribed dosages.


CONCLUSIONS
Many of the supplemental materials accompanying the prescriptions filled in this study were suboptimal;CMI was written at reading levels exceeding that of many parents,and the largest marked dose on each OLMD varied substantially. Physicians should be cognizant of the shortcomings of supplemental materials included with many medications, whereas pharmacies should strive to provide understandable CMI (ie, written at or below sixth-grade reading level) and suitable OLMDs (ie,requiring only one measurement of medication) to promote proper medication use.
