Effects of Text Enhancement on Reduction of Look-Alike Drug Name Confusion: A Systematic Review and Meta-analysis

This study aimed to explore the effects of text enhancement on reduction of confusion caused by look-alike drug names through systematic review and meta-analysis. Methods: We searched 5 databases (from database inception to January 2020) for empirical studies that examined the effects of text enhancement on reduction of look-alike drug name–induced drug name confusion. The pooled outcome data were analyzed using either meta-analysis or a narrative synthesis approach. Results: From the 351 identified articles, 11 articles representing 20 individual trials were included. Five basic text enhancement methods were revealed, including Tall Man, red, boldface, contrast, and size enhancement, from which 4 Tall Man variants and 6 text enhancement combinations were derived. The meta-analysis results showed significant reduction in omission errors when using Tall Man (standardized mean difference [SMD] = −0.628, 95% confidence interval [CI]: −1.018 to −0.238, P = .002), red (SMD = −0.516, 95% CI: −1.002 to −0.030, P = .038), boldface (SMD = −1.027, 95% CI: −1.240 to −0.814, P
