The early mortality rate of people infected with coronavirus (COVID-2019) in Wuhan, China: Review of three retrospective studies.

Background: The infection with coronavirus and non-survivor cases have been escalated since the first inception between January and March 2020. Therefore, reviewing the collated clinical characteristics of non-survivors might assist in current preventive efforts, triaging, and management of survivors. The aim of this review was to summarize the clinical characteristics of non-survivor cases due to the infection caused by a novel coronavirus and to identify the relevant data that might put the new cases at increased mortality.

Materials And Methods: We have identified three published articles on novel coronavirus reported during December 01, 2020, to March 15, 2020, which have described the mortality rate in Wuhan, Hubei, China.

Results: The mean duration of studies (i.e., the three retrospective studies with 278 cases) was 24.7 days, and the duration of onset to dyspnea was variable between 8 and 5 days. The main reported complications were acute respiratory distress, pneumonia, acute kidney injury, and acute cardiac disease. The overall major comorbidity reported was cardiovascular diseases at 23.7% (66 of 278). The reported overall mortality rate was 8.3% (23 of 278), with the highest mortality rate of 15.0% (6 of 41) reported in Jin Yintan Hospital at Wuhan city.

Conclusions: The clinical characteristics of the non-survivors from the novel coronavirus included adult males, aged older than 50 years, having comorbidities of cardiovascular disease, respiratory distress syndrome, acute kidney injury, and diabetes with higher admission to the intensive care unit. The mortality rate was high in two of the reported studies (15.0% and 11.0%), which was decreased in the later-dated study to 3.4%.
