Popis: Introduction Studies suggest that patients with cancer are more likely to experience severe outcomes from COVID-19. Therefore, cancer centers have undertaken efforts to care for patients with cancer in COVID-free units. Nevertheless, the frequency and relevance of nosocomial transmission of COVID-19 in patients with cancer remain unknown. The goal of this study was to determine the incidence and impact of hospital-acquired COVID-19 in this population and identify predictive factors for COVID-19 severity in patients with cancer. Methods Patients with cancer and a laboratory-confirmed diagnosis of COVID-19 were prospectively identified using provincial registries and hospital databases between March 3rd and May 23rd, 2020 in the provinces of Quebec and British Columbia in Canada. Patient’s baseline characteristics including age, sex, comorbidities, cancer type, and type of anti-cancer treatment were collected. The exposure of interest was incidence of hospital-acquired infection defined by diagnosis of SARS-CoV-2 ≥ 5 days after hospital admission for COVID-unrelated cause. Co-primary outcomes were death or composite outcomes of severe illness from COVID-19 such as hospitalization, supplemental oxygen, intensive-care unit (ICU) admission and/or mechanical ventilation. Results A total of 252 patients (N=249 adult, and N=3 pediatric) with COVID-19 and cancer were identified, and the majority were residents of Quebec (N=233). One-hundred-and-six patients (42.1%) received active anti-cancer treatment in the last 3 months prior to COVID-19 diagnosis. During a median follow-up of 25 days, 33 (13.1%) required admission to the ICU, and 71 (28.2%) died. Forty-seven (19.1%) had a diagnosis of hospital-acquired COVID-19. Median overall survival was shorter in those with hospital-acquired infection, compared to a contemporary community-acquired population (27 days vs unreached, HR 2.3, 95% CI 1.2-4.4, p=0.0006). Multivariate analysis demonstrated that hospital-acquired COVID-19, age, ECOG status, and advanced stage of cancer were independently associated with death. Interpretation Our study demonstrates a high rate of nosocomial transmission of COVID-19, associated with increased mortality in both univariate and multivariate analysis in the cancer population, reinforcing the importance of treating patients with cancer in COVID-free units. We also validated that age and advanced cancer were negative predictive factors for COVID-19 severity in patients with cancer.
Highlights • We found a high rate of nosocomial transmission of COVID-19 in patients with cancer. • Nosocomial COVID-19 increased mortality compared to community-acquired infection. • Nosocomial COVID-19, age, ECOG, and stage were independently associated with death. • COVID-free units and infection control procedures are required to protect patients.
