Kevin Barry [patient partner]

I have been an active volunteer in the Patient Voices Network for a few years now. Working in the Nursing profession for forty years in Canada and England I have always been conscious of providing safe, ethical care to patients and their families. The ActionADE project when successfully concluded will provide BC citizens with a greater level of confidence in the drug prescribing methods of BC’s healthcare providers and improved communication between patients and their healthcare team members. I am excited to be providing a contribution on behalf of BC patients to the important work of this research team.
