At the Patient-Partnered Diagnostic Center of Excellence (the Center), we believe that better diagnosis begins with the people most affected: patients. Our mission is to reduce diagnostic errors and improve diagnostic safety by working with patients—not just for them. We’re a collaborative, international initiative that brings together patients, families, clinicians, and researchers to co-create practical, patient-centered, and equitable solutions. We center lived experience and strive for safer, more inclusive care for everyone.
