Category: Article Summary

Topic: Clinical Characteristics and Health Care Setting

Keywords (Tags): clinical characteristics, sequelae

• A systematic review of PubMed and Embase to investigate characteristics of lung sequelae in COVID-19 patients found that about half of COVID-19 patients still had residual abnormalities on chest computerized tomography (CT) and pulmonary function tests (PFTs) at about 3 months after hospital discharge. Residual CT abnormalities were present in 55.7% (95% CI 41.2-70.1) of patients. The most frequent chest CT abnormality was ground glass opacity in 44.1% (95% CI 30.5-57.8), followed by parenchymal band or fibrous stripe in 33.9% (95% CI 18.4-49.4).
