Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Background: To investigate the prevalence of SARS-CoV-2 infection in hospitalized patients with vascular disorders after implementing institutional and governmental safety measures.

Materials and Methods: Vascular patients (VPs) admitted to our tertiary care hospital were routinely tested for SARS-CoV-2 infection on a two days basis between March and December, 2020. The prevalence of SARS-CoV-2 was compared between VPs and two independent Austrian populations (April and November 2020) tested by the Austrian Ministry of Science. The results were also compared to a cohort of health care personnel (HCP) working in close proximity to the study patients, tested weekly, between March and December, 2020. RT-PCR and antigen test were used to detect SARS-CoV-2.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patient cohort:

all patients with vascular disorders consecutively admitted at our tertiary care hospital from March 16 to December 07, 2020

PCR

Intervention Type DIAGNOSTIC_TEST

Nasal or pharyngeal respiratory swabs were routinely taken of each patient admitted at our departments and repeated regularly at 48 h intervals during the inpatient stay.

In the HCP cohort testing for SARS-CoV-2 RNA was performed, on a weekly basis, at the Department of Laboratory Medicine, Medical University of Vienna, Austria, using real-time polymerase chain reaction (RT-PCR). Comparability of the results of all test methods used was confirmed by participation in international quality control ring trials.

Control cohort:

data of two nationwide PCR-based studies conducted in a representative random sample, from April 1-6, and November 12-14, 2020, collected by the Austrian Ministry of Science and the Austrian Red Cross to estimate the spread of SARS-CoV-2 infection among the non-hospitalized Austrian population.

HCP cohort:

HCP worker data, including nurses, nurse technicians, physicians, surgical personal, physical therapists, nurse practitioners, environmental service workers, administrative staff, and dietitians, working in close proximity to admitted patients at our tertiary care hospital from March 16 to December 07, 2020.
