59. Persistence of Respiratory and Non-respiratory Symptoms Among COVID-19 Patients Seeking Care at an Ambulatory COVID-19 Center

Abstract

BackgroundWhile hospitalized COVID-19 patients are well described in the literature, studies of the natural history and ambulatory cases are limited. We aim to describe the symptoms and clinical course of COVID-19 among ambulatory patients seen at the Emory University multidisciplinary Acute Respiratory Clinic (ARC) developed to care for patients with confirmed or suspected COVID-19.MethodsPCR-confirmed COVID-19 cases seen at ARC from 4/3–5/16/2020 were included in a retrospective chart review. Encounters were classified as acute, subacute, or convalescent depending on the duration since illness onset (< 1, 1–4, or >4 weeks, respectively). Demographic, clinical, physical exam, diagnostic test, and disposition data were abstracted and analyzed with standard descriptive statistics.ResultsAmong 404 visits at ARC, 127 (31.4%) were for confirmed COVID-19 illness (107 unique patients with 1–4 visits). The majority (75.7%) of patients were female, and the median age was 55 years (range 24–89). Patients presented during acute, subacute, and convalescent phases of illness (15.7%, 58.3%, and 26.0%, respectively; Table). Prevalent co-morbidities included hypertension (39.3%), obesity (27.1%), diabetes (20.6%), and asthma (21.5%). While measured or subjective fever was reported in the majority of acute visits (60.0%), it was less common in subacute and convalescent encounters (27.0% and 30.3%). Cough was commonly reported in acute, subacute, and convalescent visits (70.0%, 79.7%, 66.7%), as were dyspnea on exertion (45.0%, 70.3%, 66.7%) and chest tightness (40.0%, 40.5%, 60.6%). Although smell or taste alteration was present in almost half of acute and subacute patients, it was only reported in a quarter of convalescent patients. Among the three stages of illness, transfers from ARC to the ED or direct hospitalizations occurred in 15.0%, 23.0%, and 12.1% of acute, subacute and convalescent visits, respectively. Table Timecourse of Symptoms among COVID-19 Patients in the Ambulatory Context ConclusionFollowing acute illness, COVID-19 patients can experience persistent symptoms, primarily respiratory symptoms, which can be severe enough to warrant hospitalization. Clinics evaluating recovering patients should prepare to manage these symptoms. Further study of the pathophysiology and treatment of persistent pulmonary symptoms in COVID-19 is needed.Disclosures All Authors: No reported disclosures
