Overview

My areas of research interest lies within the area of pediatric drug allergy. Many patients labelled as allergic to medications are not actually allergic – this has significant impact on medication selection for subsequent illnesses, and leads to less optimal medication being prescribed to the patient at increased costs to the health care system. This is of particular concern in patients with complex medical needs who often require admission to hospital or treatment with medications. I hope that by developing a program aimed at clarifying the nature of reactions and de-labeling allergy, we can optimize medication selection and patient care, both in hospital and in the community.

I am also involved in projects involving a variety of aspects of food allergy, including optimizing management of allergic reactions by patients/families and describing unusual cases of food allergy in pediatrics.

Research

Epinephrine Autoinjector Study
Families in Pediatric Allergy Clinic often report that they are fearful of using an epinephrine autoinjector despite receiving education on indications for use and technique. It is very important that patients and caregivers have the skills, knowledge and confidence to administer the epinephrine autoinjector when indicated. The goal of this study is to assess the impact of self or caregiver-administrated epinephrine in a medically supervised setting on the confidence of patient and/or caregivers for future use of epinephrine autoinjector.

Penicillin de-labelling Study:
Penicillin allergy is a common drug allergy diagnosis. However, upon assessment by Allergists, many people are not actually allergic. Patients can be erroneously labelled as allergic due to misclassification of a suspected reaction. As a result, many patients will receive alternative antibiotics that are more expensive, potentially less effective, more toxic, and may increase risk of antibiotic resistance. The goal of this study is to develop assessment tools and a program to help pediatric health care providers identify those who are at low risk of penicillin allergy and de-label them.
