The Potential for Remotely Mentored Patient-Performed Home Self-Monitoring for New Onset Alveolar-Interstitial Lung Disease.

ABSTRACT

Purpose: Coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is an acute respiratory illness. Although most infected persons are asymptomatic or have only mild symptoms, some patients progress to devastating disease; such progression is difficult to predict or identify in a timely manner. COVID-19 patients who do not require hospitalization can self-isolate at home. Calls from one disease epicenter identify the need for homebased isolation with telemedicine surveillance to monitor for impending deterioration. Methodology: Although the dominant approach for these asymptomatic/paucisymptomatic patients is to monitor oxygen saturation, we suggest additionally considering the potential merits and utility of home-based imaging. Chest computed tomography is clearly impractical, but ultrasound has shown comparable sensitivity for lung involvement, with major advantages of short and simple procedures, low cost, and excellent repeatability. Thoracic ultrasound may thus allow remotely identifying the development of pneumonitis at an early stage of illness and potentially averting the risk of insidious deterioration to severe pneumonia and critical illness while in home isolation. Conclusions: Lung sonography can be easily performed by motivated nonmedical caregivers when directed and supervised in real time by experts. Remote mentors could thus efficiently monitor, counsel, and triage multiple home-based patients from their "control center." Authors believe that this approach deserves further attention and study to reduce delays and failures in timely hospitalization of home-isolated patients.
