Dr. Herridge is committed to evaluating and improving long-term patient and family caregiver outcomes after critical illness. Since 1997, her group has completed three cohort studies: 5-year outcomes in survivors of ARDS (co-PI Dr. Angela Cheung); 1-year outcomes in survivors of SARS (co-PI Dr. Catherine Tansey); 2-year outcomes in patients after 7 days of mechanical ventilation and their family caregivers (RECOVER Program Phase I co-PI Dr. Jill Cameron). Currently, Dr. Herridge is co-leading (with Dr. Angela Cheung) the CIHR-funded CANCOV Program (Prospective multi-centre 2-year Cohort Study of COVID-19 patients and caregivers).
