ARTICLE HIGHLIGHTS
Research background

There is limited data on the difference in the clinical characteristics and outcomes of patients with severe coronavirus disease 2019 (COVID-19) infection in the summer compared to the fall surge.

Research motivation

Surges in COVID-19 cases are associated with increased hospitalizations including the intensive care units (ICU) placing significant strains on hospital resources. Knowledge about the differences in the clinical characteristics and outcomes between each surge will provide useful information on how to decrease related morbidity and mortality.

Research objectives

To compare the sociodemographic, clinical characteristics, and outcomes among mechanically ventilated patients with severe COVID-19 infection admitted to the (ICU) during the summer and fall surges in the year 2020.

Research methods

The authors included mechanically ventilated COVID-19 patients managed at Grady Memorial Hospital (GMH) from April 1 and December 31, 2020. Patients were categorized into two groups, those admitted in the summer (June 15, 2020 - August 15, 2020) and fall (October 15, 2020 - December 31, 2020). We compared patients' characteristics and outcomes using descriptive and inferential statistics.

Research results

A total of 220 patients were admitted to the GMH ICU and mechanically ventilated for COVID-19 (125 during the summer surge and 95 during the fall surge). Patients admitted in the fall had fewer comorbidities, lower mortality rate, shorter length of stay on the mechanical ventilator and shorter ICU length of stay.

Research conclusions

Patients admitted with severe COVID-19 infection requiring mechanical ventilation had better outcomes in the fall than in summer.

Research perspectives

Further studies are needed to replicate these findings.
