Long-term Characterization of Patients With Severe/Critical Infection by COVID-19 Virus

Clinical, Radiological, Lung Function, and Quality of Life Characterization of Patients With Severe/Critical Infection by SARS-COV-2 (COVID-19) Virus, After 6 and 12 Months of Hospital Discharge

A descriptive study to characterize clinical, radiological, lung function and quality of life alterations in patients who survived a severe or critical disease caused by SARS-COV-2 virus, who were treated in the intensive care unit of a high complexity institution in Cali, Colombia.

Cohorts and Interventions

Group / Cohort

Intervention / Treatment

Severe and critical COVID-19 survivors; Radiological alterations assessed by chest radiography and/or thoracic computed tomography Lung function alterations assessed by spirometry, diffusing capacity for carbon monoxide, 6 minute walk. Quality of life alterations: saint george respiratory questionnaire

Radiation: chest radiography; 6 and 12 months after hospital discharge. If the study is normal at 6 months it will not be repeated at 12 months.; Radiation: thoracic computed tomography scan; 6 and 12 months after hospital discharge, if the patient had a CT scan upon admission to the hospital. If the study is normal at 6 months it will not be repeated at 12 months.; Diagnostic test: spirometry; 6 and 12 months after hospital discharge. If the study is normal at 6 months it will not be repeated at 12 months.; Diagnostic test: Diffusing capacity of carbon monoxide; 6 and 12 months after hospital discharge. If the study is normal at 6 months it will not be repeated at 12 months.; Diagnostic test: 6 minute walk test; 6 and 12 months after hospital discharge. If the study is normal at 6 months it will not be repeated at 12 months.; Diagnostic test: saint george respiratory questionnaire; 6 and 12 months after hospital discharge.
