The evidence was appraised by preferentially looking at higher levels of evidence such as systematic reviews and/or meta-analyses of RCTs and individual RCTs. The immediate assessment of patients having an allergic reaction and prompt administration of epinephrine, if criteria for anaphylaxis are met, promote optimal outcomes. Health Technol Assess. ...
