 This study found that post-COVID-19 breathlessness was common among patients who had been hospitalized for COVID-19. It also identified several risk factors for developing post-COVID-19 breathlessness, including socioeconomic deprivation, pre-existing depression or anxiety, being female, longer hospital stay, and black ethnicity. Additionally, the study found that post-COVID-19 breathlessness was associated with worse performance on the shuttle walk test and forced vital capacity, but not with obstructive airflow limitation. Finally, the study developed a prediction model which had fair discrimination and good calibration. This article was offered by Luke Danes, Banksheng, Omar El-Nima, and others.
