BACKGROUND: Literature has shown that computerized @entity1011 clearance alerts reduce errors during prescribing, and applying @entity1 factors principles may further reduce errors. Our objective was to apply @entity1 factors principles to @entity1011 clearance alert design and assess whether the redesigned alerts increase usability and reduce prescribing errors compared with the original alerts. METHODS: Twenty Veterans Affairs (VA) outpatient providers (14 physicians, 2 nurse practitioners, and 4 clinical pharmacists) completed 2 usability sessions in a counterbalanced study to evaluate original and redesigned alerts. Each session consisted of fictional @entity1 scenarios with 3 medications that warranted prescribing changes because of @entity8 , each associated with @entity1011 clearance alerts. Quantitative and qualitative data were collected to assess alert usability and the occurrence of prescribing errors. RESULTS: There were 43% fewer prescribing errors with the redesigned alerts compared with the original alerts (P  = .001). Compared with the original alerts, redesigned alerts significantly reduced prescribing errors for @entity208 and @entity5018 (85% vs 40% and 65% vs 25%, P  = .012 and P  = .008, respectively), but not for @entity1482 (85% vs 65%). Nine providers (45%) voiced @entity911 about why the alert was appearing when they encountered the original alert design. When laboratory links were presented on the redesigned alert, laboratory information was accessed 3.5 times more frequently. CONCLUSIONS: Although prescribing errors were high with both alert designs, the redesigned alerts significantly improved prescribing outcomes. This investigation provides some of the first evidence on how alerts may be designed to support safer prescribing for @entity1 with @entity8 .
