Background:
Penicillin allergy testing (PAT) can decrease the use of unnecessary antibiotics by clarifying who is truly allergic.
Objectives:
This article describes the development and implementation of an oncology outpatient nurse-driven PAT program.
Methods:
A nurse-driven program, initiated with allergy screening at the first encounter, was designed to identify patients with oncologic diagnoses eligible for PAT. Once verified eligible, patients undergo a three-step testing process (scratch test, intradermal injection, and IV challenge dose) administered by the infusion nurse.
Findings:
From November 2018 to December 2019, 82 outpatients with reported penicillin allergies were screened; 90% were eligible for PAT, and 97% of patients tested were negative for penicillin allergy. A significant reduction in aztreonam use among patients admitted for hematopoietic stem cell transplantation was also noted as compared to before PAT was offered.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
