Methods: A review of patients previously admitted to STVHCS with self-reported penicillin allergy was initially made to establish accuracy of documentation in the electronic medical record (EMR). Once this was established, a team of clinical pharmacy specialists made calls to patients with newly documented penicillin allergies using a standardized questionnaire to clarify allergy history. This questionnaire included five key elements of accurate allergy history including name of the medication, nature of the reaction, date of the reaction, timing of the reaction in relation to taking the antibiotic, and other related antibiotics received since the allergy occurred (e.g. other beta lactams).
Results: 252 unique patients with a penicillin allergy were admitted to STVHCS between 1/1/14 and 3/31/14. Nature of the reaction was documented 54% of the time. Less than 2% of the other key elements were recorded, resulting in a 33% accuracy rate. Between 10/1/2014 and 1/31/2014, 229 patients had a new penicillin allergy documented in the EMR. Of those, 24% were contacted to complete the questionnaire. Upon intervention, nature of the reaction was documented 93%. Documentation of all other key elements was improved to 66% or better. This resulted in an accuracy rate of 86.2%.
