Background Since the COVID-19 pandemic began, there have been concerns related to the preparedness of healthcare workers (HCWs). This study aimed to describe the level of awareness and preparedness of hospital HCWs at the time of the first wave. Methods This multinational, multicenter, cross-sectional survey was conducted among hospital HCWs from February to May 2020. We used a hierarchical logistic regression multivariate analysis to adjust the influence of variables based on awareness and preparedness. We then used association rule mining to identify relationships between HCW confidence in handling suspected COVID-19 patients and prior COVID-19 case-management training. Results We surveyed 24,653 HCWs from 371 hospitals across 57 countries and received 17,302 responses from 70.2% HCWs overall. The median COVID-19 preparedness score was 11.0 (interquartile range [IQR] = 6.0–14.0) and the median awareness score was 29.6 (IQR = 26.6–32.6). HCWs at COVID-19 designated facilities with previous outbreak experience, or HCWs who were trained for dealing with the SARS-CoV-2 outbreak, had significantly higher levels of preparedness and awareness (p<0.001). Association rule mining suggests that nurses and doctors who had a ’great-extent-of-confidence’ in handling suspected COVID-19 patients had participated in COVID-19 training courses. Male participants (mean difference = 0.34; 95% CI = 0.22, 0.46; p<0.001) and nurses (mean difference = 0.67; 95% CI = 0.53, 0.81; p<0.001) had higher preparedness scores compared to women participants and doctors. Interpretation There was an unsurprising high level of awareness and preparedness among HCWs who participated in COVID-19 training courses. However, disparity existed along the lines of gender and type of HCW. It is unknown whether the difference in COVID-19 preparedness that we detected early in the pandemic may have translated into disproportionate SARS-CoV-2 burden of disease by gender or HCW type.

Summary SARS Coronavirus‐2 is one of the most widespread viruses globally during the 21st century, whose severity and ability to cause severe pneumonia and death vary. We performed a comprehensive systematic review of all studies that met our standardised criteria and then extracted data on the age, symptoms, and different treatments of Covid‐19 patients and the prognosis of this disease during follow‐up. Cases in this study were divided according to severity and death status and meta‐analysed separately using raw mean and single proportion methods. We included 171 complete studies including 62,909 confirmed cases of Covid‐19, of which 148 studies were meta‐analysed. Symptoms clearly emerged in an escalating manner from mild‐moderate symptoms, pneumonia, severe‐critical to the group of non‐survivors. Hypertension (Pooled proportion (PP): 0.48 [95% Confident interval (CI): 0.35–0.61]), diabetes (PP: 0.23 [95% CI: 0.16–0.33]) and smoking (PP: 0.12 [95% CI: 0.03–0.38]) were highest regarding pre‐infection comorbidities in the non‐survivor group. While acute respiratory distress syndrome (PP: 0.49 [95% CI: 0.29–0.78]), (PP: 0.63 [95% CI: 0.34–0.97]) remained one of the most common complications in the severe and death group respectively. Bilateral ground‐glass opacification (PP: 0.68 [95% CI: 0.59–0.75]) was the most visible radiological image. The mortality rates estimated (PP: 0.11 [95% CI: 0.06–0.19]), (PP: 0.03 [95% CI: 0.01–0.05]), and (PP: 0.01 [95% CI: 0–0.3]) in severe‐critical, pneumonia and mild‐moderate groups respectively. This study can serve as a high evidence guideline for different clinical presentations of Covid‐19, graded from mild to severe, and for special forms like pneumonia and death groups.

Background: The outbreak of Coronavirus disease (COVID-19) caused by a novel coronavirus (named SARS-CoV-2) has gained attention globally and has been recognized as a Public Health Emergency of International Concern (PHEIC) by the World Health Organization (WHO) due to the rapidly increasing number of deaths and confirmed cases. Health care workers (HCWs) are vulnerable to this crisis as they are the first frontline to receive and manage COVID-19 patients. In this multicenter multinational survey, we aim to assess the level of awareness and preparedness of hospital staff regarding COVID-19 all over the world.Methods: From February to March 2020, the web-based or paper-based survey to gather information about the hospital staff's awareness and preparedness in the participants' countries will be carried out using a structured questionnaire based on the United States Centers for Disease Control and Prevention (CDC) checklist and delivered to participants by the local collaborators for each hospital. As of March 2020, we recruited 374 hospitals from 58 countries that could adhere to this protocol as approved by their Institutional Review Boards (IRB) or Ethics Committees (EC).Discussion: The awareness and preparedness of HCWs against COVID-19 are of utmost importance not only to protect themselves from infection, but also to control the virus transmission in healthcare facilities and to manage the disease, especially in the context of manpower lacking and hospital overload during the pandemic. The results of this survey can be used to inform hospitals about the awareness and preparedness of their health staff regarding COVID-19, so appropriate policies and practice guidelines can be implemented to improve their capabilities of facing this crisis and other future pandemic-prone diseases.
