Characteristics of patients who died in the Hospital Emergency Service during the SARS-CoV-2 pandemic: a retrospective cohort study in a tertiary hospital in Spain.

Abstract

Abstract Objective: The objective of this study is to analyze the characteristics of patients who died in the Hospital Emergency Department (HED) of a Spanish third-level hospital, with a special focus on those who died due to SARS-CoV-2. Methods: A retrospective cohort study was conducted, including all patients over 18 years old who died in the Hospital Emergency Department (HED) of a Spanish third-level hospital located in Badalona, Spain, from June 2019 to December 2020. Various sociodemographic, clinical, and diagnostic variables of the patients were analyzed to identify potential risk factors associated with mortality. Results: During the first wave of the COVID-19 pandemic, a total of 72 patients died in the HED, representing a 42% increase compared to the pre-pandemic period. Of the deceased patients, 11% were attributed to SARS-CoV-2. Furthermore, it was found that patients who died from SARS-CoV-2 during the first wave were significantly younger than those in the second wave, with an average age of 78.6 ± 3.1 years in the first wave and 91.8 ± 4.8 years in the second wave. No significant differences were found regarding gender or associated comorbidities. Conclusions: Overall, the mortality rate at the HED in relation to COVID-19 was low, and infected patients died at younger ages during the first wave compared to the second wave.
