Description of intervention(s) / exposure
Appropriate use of antibiotics is paramount in the era of multidrug resistant organisms and a dwindling new antibiotic pipeline. Data to guide the development of a safe, cost-effective and scalable antibiotic de-labelling strategy will improve health outcomes such as hospital length of stay, and reduce complications and costs associated with broad-spectrum antibiotics. We need to understand current practice, including variations in protocol, adherence to guidelines and resource requirements as a first step, then look to standardise prospective testing and de-labelling strategies.
This observational, prospective study will be conducted in two phases. Phase 1 (months 1-5) will describe current antibiotic de-labelling practice at participating sites and the outcomes. Phase 2 (months 7-11) will compare the same endpoints as phase 1 after the implementation of an evidence-based, standardised antibiotic de-labelling protocol.
It is anticipated that the standardised de-labelling protocol to be used in phase 2 of the study will be implemented following completion of this study.

Outcomes
Primary outcome [1] 306377 0
Proportion of patients assessed for penicillin allergy that are de-labelled.
Patients undergoing penicillin allergy testing and/or challenge at a hospital specialist service will be consented to the study to allow for collection of information about the processes and outcomes of their penicillin allergy testing . This will be collected prospectively in the patients medical record (or a pre-printed data collection form) to be then entered into a Research electronic data capture system called REDCap.

Primary outcome [2] 306378 0
Proportion of patients de-labelled who consider themselves (or their child) non-allergic to penicillin at follow up contact in 8 weeks.

8 week follow up
Secondary outcome [1] 348287 0
Adherence of testing to local (hospital) protocols in Phase 1.
This will be assessed by comparing data entered into REDCap versus data collection requirements of each hospitals standard of care testing protocol.

Month 5
Secondary outcome [2] 348288 0
Adherence of testing to standardised protocol in Phase 2.
This will be assessed by comparing data entered into REDCap versus data collection requirements of the phase 2 standardised protocol.

Month 11
Secondary outcome [3] 348292 0
Proportion of patients who received penicillin or alternate antibiotic between assessment and follow-up at 8 weeks.
This data will be collected by contacting the patient by telephone or email.

Summary
Brief summary
AIMS: This research project aims to collect information about the processes and outcomes of antibiotic allergy testing in a standardised way in order to improve future quality of care and outcomes for people with antibiotic allergies. The focus of this project will be on individuals with penicillin allergy labels.
PARTICIPANTS: Patients who present to a hospital specialist service for assessment of penicillin allergy will be asked if they would like to participate.
METHODS: Collection of information that will be routinely collected at the patient's routine penicillin allergy assessment visit and a follow up telephone call or email 8 weeks after the visit. An optional blood sample may be collected on the day to store for future research related to drug allergy.
EXPECTED OUTCOMES: Improve access to antibiotic allergy delabelling
services, improve the way in which appropriate advice after delabelling
is provided to patients, and develop education resources for teaching and
implementation of best practice into other nonhospital settings. This will provide safer and more cost effective care for all.
