At Houston Methodist hospitals, frontline nurses are spearheading a ‘delabeling’ initiative that aims to accurately assess patients’ penicillin allergies. This important measure is set in motion to ensure timely and efficient administration of effective antibiotics, thereby reducing the likelihood of extended hospital stays and potentially curbing mortality rates. The significance of this strategy resides in its unique reliance on nursing staff—a formidable force within the hospital landscape—to actively redesign the process in assessing and managing penicillin allergies.
This initiative, pioneered by M. Yasser Alsafadi, M.D., medical director of the Antimicrobial Stewardship Program at Houston Methodist, endeavors to reassess the penicillin allergies of patients and adjust their medical records appropriately. This allows for the provision of the most optimal antibiotic to each patient. Involving frontline nurses in the reassessment process could potentially alleviate the strain on physicians who struggle to prescribe alternatives to penicillin and its derivatives—alternatives that may not always be as effective.
The initiative utilizes the PEN-FAST clinical tool, a set of questions designed to identify patients who carry a low risk of actual penicillin allergy. Nurses at Houston Methodist have been entrusted with this modified tool, empowering them to conduct these necessary assessments upon patient admission. Despite the prevalence of reported penicillin allergies in the U.S.—nearly 10% of the population—the Centers for Disease Control and Prevention (CDC) indicates that a mere 1% hold a true allergy. Consequently, many individuals incorrectly labelled as allergic could safely tolerate the medication.
Accurate identification of penicillin allergies also enables physicians to utilize more effective antibiotics prior to surgical procedures. For example, cefazolin—a relative of penicillin—is often the antibiotic of choice for prophylaxis in most surgeries. Administering cefazolin prior to undergoing surgery can improve patient outcomes by preemptively fighting infections and reducing complications, thereby speeding recovery time.
Yet, the mislabelling of penicillin allergies often leads prescribers to avoid cefazolin, believing patients would react negatively to the entire family of antibiotics—highlighting the indirect ramifications of such mislabels. This system-wide initiative, spanning two years, involves multiple teams including infectious diseases, nursing, pharmacy, Information Technology (IT), electronic clinical decision support, and data and analytics, and aims to track real-time statistics for sustainable and reproducible results.
