    Background: National data from diverse institutions across the United States are critical for guiding policymakers as well as clinical and public health leaders. This study characterized a large national cohort of patients diagnosed with COVID-19 in the U.S., compared to patients diagnosed with viral pneumonia MESHD pneumonia HP and influenza. Methods and Findings: We captured cross-sectional information from 36 large healthcare systems in 29 U.S. states, participating in PCORnet, the National Patient-Centered Clinical Research Network. Patients included were those diagnosed with COVID-19, viral pneumonia MESHD pneumonia HP and influenza in any care setting, starting from January 1, 2020. Using distributed queries executed at each participating institution, we acquired information for patients on care setting (any, ambulatory, inpatient or emergency department, mechanical ventilator), age TRANS, sex, race, state, comorbidities (assessed with diagnostic codes), and medications used for treatment of COVID-19 (hydroxychloroquine with or without azithromycin; corticosteroids, anti-interleukin-6 agents). During this time period, 24,516 patients were diagnosed with COVID-19, with 42% in an emergency department or inpatient hospital setting; 79,639 were diagnosed with viral pneumonia MESHD pneumonia HP (53% inpatient/ED) and 163,984 with influenza (41% inpatient/ED). Among COVID-19 patients, 68% were 20 to <65 years of age TRANS, with more of the hospitalized/ED patients in older age TRANS ranges (23% 65+ years vs. 12% for COVID-19 patients in the ambulatory setting). Patients with viral pneumonia MESHD pneumonia HP were of a similar age TRANS, and patients with influenza were much younger. Comorbidities were common, especially for patients with COVID-19 and viral pneumonia MESHD pneumonia HP, with hypertension HP hypertension MESHD (32% for COVID-19 and 46% for viral pneumonia HP pneumonia MESHD), arrhythmias HP arrhythmias MESHD (20% and 35%), and pulmonary disease MESHD (19% and 40%) the most common. Hydroxychloroquine was used in treatment for 33% and tocilizumab for 11% of COVID-19 patients on mechanical ventilators (25% received azithromycin as well). Conclusion and Relevance: PCORnet leverages existing data to capture information on one of the largest U.S. cohorts to date of patients diagnosed with COVID-19 compared to patients diagnosed with viral pneumonia MESHD pneumonia HP and influenza.

    Background: Hydroxychloroquine and Azithromycin use is associated with QT interval prolongation MESHD and arrhythmias HP arrhythmias MESHD. Despite ongoing multiple clinical trials for treatment of COVID19 infection MESHD, no definite cardiac safety protocols were proposed. The aim of our study was to assess cardiac safety in COVID-19 patients treated with the combination of Hydroxychloroquine and Azithromycin using close monitoring and arrhythmia HP arrhythmia MESHD risk management plan.Methods and results: We retrospectively examined arrhythmia HP arrhythmia MESHD safety of treatment with Hydroxychloroquine and Azithromycin in the setting of pre-defined cardiac arrhythmia MESHD arrhythmia HP risk management plan. 81 patients were included from March 23rd to May 10th 2020. The median age TRANS was 59 years, 58.0% were female TRANS. The majority of the study population (82.7%) had comorbidities, 98.8% had radiological signs of pneumonia HP pneumonia MESHD. 7 patients (8.6%) had QTc prolongation MESHD of ≥500 ms. The treatment was discontinued in 4 patients (4.9%). 14 patients (17.3%) experienced QTc≥480 ms and 16 patients (19.8%) had an increase of QTc≥60 ms. None of the patients developed ventricular tachycardia HP ventricular tachycardia MESHD. The risk factors significantly associated with QTc≥500 ms were hypokalemia HP hypokalemia MESHD (p = 0.032) and use of diuretics during the treatment (p = 0.020). Three patients had a lethal outcome; none of them associated with ventricular arrhythmias HP ventricular arrhythmias MESHD.Conclusion: We recorded a low incidence of QTc prolongation MESHD ≥500 ms and no ventricular tachycardia HP ventricular tachycardia MESHD events in COVID-19 patients treated with Hydroxychloroquine and Azithromycin using cardiac arrhythmia MESHD arrhythmia HP risk management plan.

    On December 31st, 2019 the China National Health Commission (NHC) reported that an unknown cause of pneumonia HP pneumonia MESHD had been detected in Wuhan in Hubei province. On February 12th, the disease caused by novel coronavirus (2019-nCoV) has a formal name, COVID-19. On January 20th, 2020, the first case of COVID-19 was confirmed in Korea. Among the deaths, age TRANS-specific death rate was the highest among cases over 70’s, with underlying diseases in their circulatory system, such as myocardial infraction, cerebral infraction, arrythmia MESHD, and hypertension HP hypertension MESHD. Patients with underlying disease who are 70 years of age TRANS or older should recognize that there is a high possibility of developing a serious disease in case of viral infection MESHD and follow strict precautions.
