Cut It Out! Removing EHR Allergy Warnings to Improve Antimicrobial Stewardship

November 12, 2021

WARNING: Patient has a penicillin allergy! Do you want to continue with this cephalexin order?

Would the removal of EHR warnings about potential penicillin allergies when cephalosporins are ordered be helpful or harmful?
