Overview of penicillin de-labelling protocols at various institutions. 1Institutions with inpatient programs: SPH, VGH Internal Medicine, LGH, BCCH. 2Institutions with outpatient programs: SPH, VGH LBMT Program, BCWH (pregnant patients only), LGH. 3LGH’s obstetric de-labelling program does not risk stratify patients, and follows the “high-risk” pathway. 4Only BCCH’s protocol has a “moderate-risk” category; all other institutions have only high and low-risk categories. 5The reagents used for skin testing vary based on the institution. BCCH, BCWH and LGH use Penicillin G. VGH and SPH test both Penicillin G and a minor determinant mixture. 6 “Pass” is defined as having a negative skin test and not reacting to the oral challenge/DOC. In contrast, “fail” is defined as having a positive skin test or having a reaction to the oral challenge/DOC
