ABSTRACT
BackgroundThe Coronavirus disease 2019 (COVID-19) pandemic has had significant global impact. While public health interventions and universal health insurance has been credited with minimizing transmission rates in Canada relative to neighboring countries, significant morbidity and mortality have occurred nationwide. We sought to determine factors associated with differences in gastrointestinal outcomes in COVID-19 patients at a Canadian hospital. MethodsWe collected data from 192 hospital records of COVID-19 patients across seven Hamilton Health Sciences hospitals, a network of academic health centres serving one of the largest metropolitan areas in Canada. Statistical and correlative analysis of symptoms, comorbidities, and mortality were performed. ResultsThere were 192 patients. The mean age was 57.6 years (SD=21.0). For patients who died (n=27, 14%), mean age was 79.2 years old (SD=10.6) versus 54 years for survivors (SD=20.1). There was a higher mortality among patients with older age (p=0.000), long hospital stay (p=0.004), male patients (p=0.032), and patients in nursing homes (p=0.000). Patients with dyspnea (p=0.028) and hypertension (p=0.004) were more likely to have a poor outcome. Laboratory test values that were significant in determining outcomes were an elevated INR (p=0.007) and elevated creatinine (p=0.000). Cough and hypertension were the most common symptom and comorbidity, respectively. Diarrhea was the most prevalent (14.5%) gastrointestinal symptom. Impaired liver function was related to negative outcome (LR 5.6; p=0.018). ConclusionsIn a Canadian cohort, elevated liver enzymes, prolonged INR and elevated creatinine were associated with poor prognosis. Hypertension was also linked to a higher likelihood of negative outcome. SUMMARY BOXO_ST_ABSWhat is already known about this subject?C_ST_ABSO_LIThe prevalence of gastrointestinal symptoms in COVID-19 patients across Canada is lacking C_LIO_LIGastrointestinal manifestations of COVID-19 are well described, and longterm sequelae of gastrointestinal tract involvement are an ongoing concern C_LI What are the new findings?O_LIThere was a significant prevalence of gastrointestinal symptoms in patients with a confirmed diagnosis of COVID-19 at one of the largest metropolitan regions across Canada C_LIO_LILiver enzyme abnormalities were common in patients at diagnosis C_LIO_LIThis report, over an 8-month period, represents the largest cohort of COVID-19 patients reported in Canada C_LI How might these results impact on clinical practice in the foreseeable future?O_LIBaseline gastrointestinal symptoms and laboratory abnormalities correlate with patient outcome in Canadian COVID-19 patients C_LIO_LIThese results enhance our knowledge of the prevalence of gastrointestinal symptoms and laboratory abnormalities in Canadian patients and offer important baseline data for longitudinal studies in these patients C_LIO_LIOur findings increase our knowledge of the epidemiology of COVID-19 in Canada and allow future comparison with international data C_LI
