Characteristics of Critically Ill Patients With Severe Acute Respiratory Syndrome Coronavirus 2 Infection (COVID-19)

Study Overview
=================
Brief Summary
-----------------
A multicenter observational, prospective cohort study that consisted of a large-scale data source of hospital ICU admissions and patient-level clinical data in Spain. The main objective is to develop a national database belonging to SEMICYUC (Spanish Society of Critical Care) to describe epidemiological and clinical characteristics and risk factors related to ICU mortality in critically ill patients admitted to ICU due to severe COVID-19 in Spain.

Detailed Description
-----------------
Design: A multicenter observational, prospective cohort study Setting: Intensive Care Units Subjects: Adult Critical patients admitted to ICU with severe community-acquired pneumonia due to confirmed SARS CoV-2 infection (COVID-19). Data Collection and Validation Data was obtained from a voluntary registry created by Spanish Society of Intensive Care Medicine-SEMICYUC. All consecutive cases admitted to the ICU were collected. There were no patients excluded from the analysis that was enrolled to participating ICU and met criteria. Data were collected using a paper CRF (case Report Form). CRF collect and record all protocol-required information, which is transcribed from patient source documents, such as hospital records and laboratory reports during the patient's participation in the study. Before being sent to the National Study Coordinator (AR) this data was de-identified (not traceable to the patient) by removing the patient's name, medical record number, etc., and giving the patient a unique study number. We implemented a double data entry model for potential errors in real-time. Data was entered twice by two different Data Entry personnel based on the same set of data collected in the paper CRFs. All data were reviewed, and values that appeared incongruent or out of range were manually validated by confirming the accuracy of the data with the Study Coordinator (AR). The database was validated and cleaned before the statistical analysis and the study database was locked to prevent any further changes, and to ensure data consistency and integrity for the statistical reporting and analysis. Sample size calculation: No statistical sample size calculation was performed a priori, and sample size was equal to the number of patients admitted to the participant's ICUs with confirmed COVID-19 during the study period.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Consecutive critically ill patients admitted to ICU with severe SARS-CoV-2 infection<br>Consecutive adult patients (> 16 years) with laboratory confirmed SARS-CoV-2 infection, detected by RT-PCR positive test of nasopharyngeal, oropharyngeal , swab or invasive respiratory samples according to the WHO recommendations. The follow-up of patients was to ICU discharge or death whichever occurred first. No interventions will be made. Only anonymized demographic data, clinical data, laboratory data and ventilatory support data will be collected. There is no standardized pharmacological treatment protocol. Only basic data are collected about the different treatments administered by the attending physician. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Epidemiologic and Clinical Characteristics and risk factors for ICU mortality in critically ill patients with COVID-19 in Spain | To determine demographics and clinical factors associated with ICU mortality at days-28 and ICU discharge | Observational period from ICU admission to data of discharge alive or date of death from any cause at days 28 of ICU length of stay and ICU discharge | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Support respiratory type and prognosis | Association between respiratory support used at ICU admission and ICU mortality | Observational period from ICU admission to data of discharge alive or date of death from any cause at days 28 of ICU length of stay and ICU discharge | 
| Comorbidities and prognosis | Association between different comorbidities (diabetes, obesity, hypertension, etc) and ICU mortality | Observational period from ICU admission to data of discharge alive or date of death from any cause at days 28 of ICU length of stay and ICU discharge |
