Background:
FLU/RSV adult hospitalizations are subject to a systematic epidemiological surveillance process performed at CHU UCL Namur (member of the Belgian Sentinel Hospital Network for severe influenza monitoring). A similar protocol has been implemented in the context of the SARS-CoV-2 pandemic outbreak. We aim to compare the epidemiological, clinical and outcome data in our hospitalized population during four FLU/RSV seasons (2015-2019) to those of two consecutive COVID-19 epidemic waves (2020 and early 2021).
Methods:
This study was conducted in a 440-beds tertiary hospital. Surveillance timelines were defined according to epidemiological criteria related to the circulation of FLU/RSV (2015-2019) and SARS-CoV2 (2020-2021) viruses in the population. Adult patients matching with a Severe Acute Respiratory Infection (SARI) case definition at the Emergency Department (ED) were tested by RT-PCR assays targeting FLU/RSV or SARS-CoV-2 viruses. Epidemiological, clinical and outcome data were retrospectively reviewed to assess the specificities of FLU/RSV and COVID-19 infections.
Results:A FLU or RSV virus was documented in 316 SARI patients (2015-2019; 4 consecutive winter seasons) and a SARS-COV-2 virus in 392 (2020-2021 epidemic waves). COVID-19 patients were more likely to need Intensive Care Unit (ICU) admission (24% vs 17%; 96/392 vs 54/316), had a higher ICU length of stay (18 days/median vs 6 for patients alive at discharge), and were younger (61 years/median vs 68 in ICU patients alive at discharge; 66 years/median vs 75 in ICU patients that died). Globally, COVID-19 patients were more likely to die from their infection (21% vs 6%; 83/392 vs 20/316), and death casualties were higher on wards than in ICU (53/82 vs 9/20; 82 years/median vs 78). Despite higher morbidity and mortality, patients hospitalized with a SARS-COV-2 infection were less susceptible than FLU/RSV patients to present comorbidities such as pulmonary disease (23% vs 47%; 92/392 vs 150/316), hematological malignancy (7% vs 19%; 27/392 vs 60/316) and immunosuppression (6% vs 16%; 25/392 vs 52/316).
Conclusions:Adult COVID-19 hospitalization patterns were significantly more severe compared to FLU/RSV in terms of hospital and ICU admissions, ICU length of stay, ICU and ward mortality rates.
