About this study
The objective of this single-center retrospective observational study is to describe spirometric abnormalities and their impact on 6-minute walk test (6MWT) and the physical component summary (PCS) of the SF-36 quality of life instrument.at least 3 months later discharge hospital.
Read the detailed description
Background: The COVID-19 pandemic has already affected more than 400 million people worldwide and resulted in at least 6 million deaths. The disease has also resulted in a growing population of individuals, with both physical and mental sequelae. Pulmonary sequelae have been the subject of several studies because the lung is the main target organ of the disease. However, there is still unknown data about the pulmonary manifestations and their spirometric patterns after a critical illness and also its consequences in quality of life.
Purpose: Up to 20% of COVID-19 patients develop severe forms of the disease and require ICU admission. Most of these patients at hospital discharge still have several limitations that impact on quality of life. Some studies have analyzed pulmonary functional alterations after a variable period of time and have found results that vary from the absence of functional alterations to restrictive and diffusion impairment. Few studies have analyzed changes in small airways, and those that have evaluated have found no changes. The objective of this single-center retrospective observational study is to describe spirometric abnormalities and their impact on 6-minute walk test (6MWT) and the physical component summary (PCS) of the SF-36 quality of life instrument.at least 3 months later discharge hospital.
Primary outcome: To describe spirometric patterns associated to severe COVID-19 survivors at least 3 months after hospital discharge.
Secondary outcomes: Correlate the results of the spirometric evaluation with the 6-minute walk test (6MWT) and the physical component summary (PCS) of the SF-36 quality of life instrument.
Methods: An observational retrospective study will be conducted, including all 18 years and older patients with severe COVID-19, confirmed by real-time reverse transcriptase-polymerase chain reaction., admitted to a 35- bed intensive care unit of a tertiary hospital from April 2020 to October 2021. Pediatric, pregnant or breastfeeding women and palliative care patients as well as chronic obstructive pulmonary disease and symptomatic asthmatic patients will be excluded. Population is estimated at 60 patients. Data collecting will be finished in February 2022. Patients routinely are assessed after at least 3 months after hospital discharge in our multidisciplinary follow-up clinic. A trained research team will routinely apply the 6 minute walk test (6MWT), a Pulmonary Function Test (PFT) and Short Form Health Survey 36 (SF-36) physical component summary (PCS) of SF-36

| Respiratory function 3 months after hospital discharge in critically ill COVID-19 patients | All critically ill adult patients admitted to the ICU with confirmed diagnosis of COVID-19 were submitted at least 3 months after hospital discharge to spirometry (FVC, FEV1, FEV1 /;FVC and FEF 25-75%), the 6-minute walk test (6MWT) and evaluation of the physical component summary (PCS) of the SF-36 quality of life instrument. Receives: Diagnostic Test: Spirometric evaluation; Diagnostic Test: Physical component summary; Diagnostic Test: 6MWT |
What is being measured
The primary outcome is the main question the study is designed to answer.
Forced vital capacity (FVC)
Forced vital capacity (FVC) is the volume of air that can forcibly be blown out after full inspiration, Measured in liters. Normal value > 80% of predicted for age, sex, heigth and ethnicity
Measured: 3 months after hospital discharge
Forced expiratory volume in 1 second (FEV1)
FEV1 is the volume of air that can forcibly be blown out in first 1 second, after full inspiration. Measured in liters. Normal value > 80%. of predicted for age, heigth and ethnicity.
Measured: 3 months after hospital discharge
FEV1 / FVC Ratio
Represents the proportion of vital capacity that the patients are able to expire in the first second of forced expiration (FEV1) to the full, forced vital capacity (FVC). The result of this ratio is expressed as FEV1%. Normal values are > 75%.of predicted that depend on age, sex, height, and ethnicity
Measured: 3 months after hospital discharge
Forced mid-expiratory flow (FEF25-75%)
Defined as the mean forced expiratory flow during the middle half of the FVC . Normal value > 65% of predictedf for age, sex, heigth and ethnicity
Measured: 3 months after hospital discharge
Secondary outcomes (2)
Physical Component Summary (PCS) of Short Form- 36 (SF-36) Instrument
PCS is composed of four scales assessing physical function, role limitations caused by physical problems, bodly pain and general health. The result scale ranges from 0 to 100, with 0 being the worst result and 100 the best.
Measured: 3 months after hospital discharge
6 Minute Walk Test
The patient is placed on a flat, rigid area 30 meters long and instructed to walk the longest tolerable distance for 6 minutes. Measured in meters. The result is given as a percentage of the normal predicted value for age, sex, height and weight calculated by the Enright and Sherril equation.
Measured: 3 months after hospital discharge

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Forced vital capacity (FVC) (time frame: 3 months after hospital discharge). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05249842, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Aug 2022.
