Long-Term Outcomes and Sequelae for 464 COVID-19 Patients Discharged from Leishenshan Hospital in Wuhan, China

Abstract

Background: While coronavirus disease 2019 (COVID-19) has emerged as a global pandemic, millions of COVID-19 patients have recovered and returned to their families and work, although the long-term outcomes remain unknown.Methods: This retrospective–prospective study analysed data for COVID-19 patients discharged from Leishenshan Hospital in Wuhan, China. Long-term outcomes were measured by Activity of Daily Living (ADL) Scale, Modified Medical Research Council (mMRC) Dyspnoea Scale, New York Heart Association (NYHA) classification, Self-rating Depression Scale (SDS), Carcinologic Handicap Index (CHI), and Modified Telephone Interview for Cognitive Status (TICS-M). Multivariable logistic regression was used to examine the risk factors of long-term outcomes.Findings: The follow-up period for the 464 patients was August 10–September 30, 2020. The most common sequelae were psychosocial problems (254 [57·7%]), respiratory function abnormality (149 [32·6%]), and cardiac function abnormality (98 [21·5%]). Rare sequelae were ADL disability (61 [13·3%]); pain (55 [12·5%]); feeding difficulties (54 [12·2%]); dysphonia (46 [10·4%]); and hyposmia (27 [6·1%]), as well as impairment in hearing (40 [9·1%]), vison (37 [8·4%]), swallowing (30 [6·8%]), and gustation (18 [4·1%]). Almost all patients (98·2%) had normal cognitive function. Risk factors associated with ADL disability were advanced age, intensive care unit (ICU) stay, and cancer, which were also associated with respiratory function abnormality. Risk factors associated with cardiac function abnormality were long hospital stay, cancer, and respiratory diseases. Advanced age, ICU stay, and nonischemic heart diseases were associated with psychosocial problems. Compared with female patients, male patients had decreased odds of declined respiratory, cardiac function, depression and anxiety, and pain.Interpretation: Nearly normal ADL, moderate cardiopulmonary function and psychosocial issues, and minor sensory abnormalities were observed in COVID-19 survivors. Advanced age, ICU stay, cancer, and female sex were adverse risk factors in long-term sequelae. These data provide a generalisable estimate of long-term outcomes for COVID-19.Trial Registration: This study was registered in the ClinicalTrial.gov database (NCT04508712).Funding: National Natural Science Foundation of China, Shanghai Shenkang Hospital Development Center, Shanghai municipal Education Commission, State Key Laboratoy of Neuroscience, and Renji Hospital.Declaration of Interests: All authors declare no competing interests.Ethics Approval Statement: This study was approved by the Institutional Research Ethics Committee of Renji Hospital, School of Medicine, Shanghai Jiaotong University (Ethical Committee approval number: KY2020-34).
