RATIONALE: The label “penicillin allergic” has a strong influence on the antibiotic selection strategy, which leads to economic and epidemiologic consequences. The lack of knowledge and guidelines among our providers intensify this problem. As healthcare providers, it is our duty to continue to inform and educate our colleagues about the importance of correctly identifying the patients not truly allergic to penicillin, as this label influences the treatment selection, and in consequence, their care.

METHODS: A pre- and post-intervention survey was applied to internal medicine residents at the University of Iowa Hospitals and Clinics. The intervention consisted of a 10 minute educational video about penicillin allergy, which was designed by the investigators. Statistical analysis involved calculating matched-pairs odds ratios and confidence intervals, with p-values obtained from McNemar’s test. Statistical significance was defined as p-value <0.05.

RESULTS: More than 50% of the participants had not received prior formal education about penicillin allergy at baseline. The educational video was effective in improving the preparedness in diagnosing a real penicillin allergy (p=0.0002), determining severity (p<0.0001), and prescribing antibiotics to patients with this label (p=0.03). There was also improvement in general knowledge about penicillin allergy including natural history (p=0.006) and diagnostic testing (p=0.01). Further educational initiatives need to be developed to improve knowledge about specific cases that represent an absolute contraindication for penicillin use.

CONCLUSIONS: This educational video was effective in improving penicillin allergy knowledge amongst our internal medicine residents. Distribution of this video can potentially lead to better management of patient’s that have the “penicillin allergic” label.
