COVID-19 Respiratory Outcomes Registry

"* EuroQol 5 Dimensional Quality of Life Questionnaire (EQ-5D).~* St. George's Respiratory Questionnaire (SGRQ)~* Impact of Events Scale Revised (IES-R)~* Generalized Anxiety Disorder 7-Item (GAD-7)~* Patient Health Questionnaire (PHQ-9)"

If required by the local site's COVID-19 guidelines, subjects should have the COVID-19 RT-PCR Nasal Swab collected at the beginning of the visit or within 5 days prior to the scheduled visit.

Venous blood will be collected using pre-labeled tubes.

Subjects will have HRCTs at Visits 1, 2, 3, and 4. Inpatient HRCT scans will be collected during the baseline visit (V0 or V1)

"A complete physical exam, including height, weight, general appearance, neck, lungs, cardiovascular system, abdomen, extremities, and skin will be performed at Visit 1.A brief physical exam will be completed at subsequent visits, including weight, general appearance, lungs, cardiovascular symptoms, extremities, and other body systems pertinent to the participants health status, at the discretion of the investigator.~Blood pressure, heart rate, and oxygen saturation will be collected at all visits, prior to blood draws and after subjects have rested."

The Medical Research Council Sum Score (MRC-SS) is used globally to detect peripheral muscle strength and to help diagnose ICU-acquired muscle weakness. The MRC-SS ranging from 0 (complete paralysis) to 60 (normal).

Each subject will have hand grip strength measured at each visit. This is being done in order to assess the maximum isometric strength of hand and forearm muscles.

Spirometry will be assessed at Visits 1, 2, 3 and 4. Each site will use its own spirometry machine. Each subject should use the same machine at each visit and conduct measurements at approximately the same time. Before any testing, the maneuver should be demonstrated to the subject. The spirometry should be reviewed by the investigator.

The site will use its own DLCO equipment for measurements at Visits, 1, 2, 3, and 4. The Single-breath DLCO maneuver will be carried out in accordance with the 2017 American Thoracic Society/European Respiratory Society (ATS/ERS) guidelines. Subjects should use the same device at approximately that same time at each visit. The maneuver should be demonstrated to the subject prior to the test.

"The 6 Minute Walk Test (6MWT) will assess exercise capacity and tolerance. 6MWTs will be conducted at Visits 1, 2, 3, and 4.~The procedure of the 6MWT should be explained and demonstrated to the subject prior to the start of the test."

The STS will be conducted at Visits 1, 2, 3, and 4 to assess the physical functioning of the adult participants.
