Evaluation of a Direct Oral Penicillin Challenge in a Rural Community

• Status: Recruiting
• Trial end date: 2024-12-15
• Target enrollment: 0
• Participant gender: All

Summary

This study aims to evaluate the outcomes of a rural-DOC Pilot clinic which will be established in the Huntsville site of Muskoka Algonquin Healthcare. Patients from the Muskoka region who are confirmed to have a low-risk penicillin allergy are eligible for participation in the DOC clinic. Following their experience with the DOC, participation in this study will be voluntary and feedback will be requested from each participant, and local primary care providers. The feedback will be used to assess the impact of the DOC clinic on participants and the medical community over the 2 - year study. Feedback will also be collected to investigate ongoing antimicrobial use for those participants who were successfully delabeled. This will be accomplished by surveying participants at six and twelve months after their DOC.
