简要总结
The CANCOV study will be the first Canadian study to provide a comprehensive evaluation of early, and 1-year, outcomes of outpatient and hospitalized COVID-19 survivors and their family caregivers, their varied trajectories and associated clinical risk factors. The overall objectives are to determine short- (in hospital) and longer-term (1, 3, 6 and 12 months post-acute hospital discharge) outcomes COVID-19+ patients across the spectrum of symptom severity, including outpatients and inpatients from GIM and ICU wards and their caregivers, and the clinical, sociodemographic, multi-omic predictors of these outcomes. By leveraging expertise from investigators across disciplines and divisions, this study presents a suite of complementary projects that explore the genetic, transcriptomic, epigenomic and immunologic evaluation of COVID-19 infection across the illness and recovery trajectory during the acute illness and in the context of multidimensional long-term outcomes. As there continues to be need for longer term follow up and research on Long-COVID, this study has added an optional extension to include 2-year, 3-year, 4-year and 5 year outcomes.
详细描述
In December 2019, a novel coronavirus (COVID-19)-infected pneumonia was identified in Wuhan, China, and is a current global pandemic. Early studies are emerging, but it is still unclear what may determine better or worse outcomes for these patients and their caregivers, and the detailed nature of long-term consequences from this infection. Current data suggest that 80-85% of patients infected with COVID-19 have mild symptoms and are not hospitalized. Of those who are hospitalized, 60-80% will be discharged from hospital after a few days, and 20-40% may require treatment in an intensive care unit (ICU) and/or mechanical ventilation (approximately 4-6% of all COVID-19 positive patients). The determining factors of these varied clinical paths are urgently needed and unknown.
The CANCOV investigator group is conducting a national Canadian COVID-19 Prospective Cohort Study (CANCOV). This will be a multi-centre, one-year follow-up of 1000 COVID-19 patients who are hospitalized in acute care hospitals (those admitted to general internal medicine (GIM) wards, and/or ICUs) and their caregivers, and 1000 non-hospitalized patients (those who were tested positive and asked to isolate at home) in participating centres across Canada. In addition, a cohort of 500-1000 patients who do not have a COVID-19 positive test but who present with a clinical diagnosis of COVID-19 will be included for investigation and comparison. The overall objectives are to determine short- (in hospital, and 2-week outcome for non-hospitalized patients) and longer-term (1, 3, 6 and 12 months post-acute hospital discharge or post diagnosis for outpatients) outcomes in patients and their caregivers, and the clinical, sociodemographic, genetic/ transcriptomic/epigenomic/immunological predictors of these outcomes. Due to patients with 'long-COVID' syndrome, the investigators have added an optional study extension for an additional 48 months, up to 5 years follow up.
By leveraging expertise from investigators across disciplines and divisions, this study presents a suite of complementary projects that explore the genetic, transcriptomic, epigenomic and immunological evaluation of COVID-19 infection across the illness and recovery trajectory in mild as well as acute illness and in the context of multidimensional long-term outcomes. The investigators will access electronic data through the GEMINI network, and explore Artificial Intelligence (AI) analyses and linkages through Institute of Clinical and Evaluative Sciences (ICES) data. This project will contribute new knowledge to outcomes in patients with COVID-19 infections and will inform large-scale public health planning, clinical care, and ongoing resource needs.

- •Physician refusal (only for hospitalized patients).
- •Patient or SDM (substitute decision maker) refuses consent.
- •No next of kin or SDM available (if patient unable to provide consent).
结局指标
主要结局
Functional Independence Measure (FIM) or acute FIM
时间窗: 1 year post diagnosis/admission
FIM is a measure of self-care, sphincter control, mobility, locomotion, communication, social and cognitive skills that has been validated and standardized in spinal cord and stroke populations. The acuteFIM is a subscale of the FIM and adapted to patients in hospital.
