Reducing Prescribing Errors Through Creatinine Clearance Alert Redesign

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