Abstract
Objectives: In 2019 Chinese authorities alerted of the appearance of a cluster of cases of unknown pneumonia related to a new type of coronavirus. Spain is among the most affected countries. Our aim is to describe the cases of COVID-19 at Infanta Sof?a University Hospital (Madrid), a public secondary hospital that increased its hospital beds to provide assistance during the outbreak.
Methods: Retrospective descriptive study of cases that met COVID-19 clinical diagnosis criteria or had a positive PCR test from February 27 to June 29, 2020. A description of demographic variables, hospital stay, mortality and the epidemiological curve was performed.
Results: Of 1612 confirmed cases, 61,8% were hospitalised, 5,0% were admitted to the ICU. 52,2% were male. The median age was 63,2 years. 13,1% were nursing home residents. 19,0% were of Latin American origin of which 6,8% were admitted to the ICU. Overall case fatality was 14,6%. We observed a biphasic epidemiological curve.
Conclusions: 60 to 79 year old males were admitted and deceased more often than women. Mortality reached 14,7%. Latin Americans were admitted more often to the ICU. Further studies about epidemiological characteristics of COVID-19 in hospitals are necessary.
