Robinson et al36 (2008)UCTGilmore Oral Reading TestCClasses and campAsthmatic children attended 2-h literacy and asthma education classes on Saturdays for 6 mo and a 5-d campED asthma-related visits dropped from 63% 6 mo before study to 33% 6 mo after study; improved self-efficacy decreased ED visits (OR: 0.27; P < .01) and hospitalizations (OR: 0.33; P < .001); improved reading level not directly associated with hospitalizationsF
Yin et al37 (2008)RCTTOFHLAPPictogram-based instructions and counselingParents of children taking daily and as-needed liquid medications were randomly assigned to receive pictogram-based medication instruction sheets with teach-back counseling or standard careIntervention caregivers significantly less likely to make errors in dosing frequency (P = .0007 daily), less likely to report incorrect medication preparation (P = .04 daily; P = .0006 as needed), and more likely to report using a standardized dosing instrument (P = .008 daily; P = .002 as needed)G
