Define the actual incidence of tracheal stenosis in patients who underwent either prolonged intubation or tracheostomy and to compare incidence, clinical course and outcome between COVID-19 and non-COVID-19 patients.
The TS1 is a national observational, multicentric, case-control clinical aiming at defining the actual incidence of tracheal stenosis in patients with COVID-19 that underwent prolonged intubation or tracheal stenosis. Information regarding anamnestic data, demographics, smoking or alcohol habits, comorbidity, previous history of prolonged ventilation or tracheostomy, and data about intensive care unit stay and treatment will be collected before discharging patients from hospital. All patients enrolled will perform an initial evaluation with a chest CT scan without contrast-enhancing at 2 months from hospital discharge along with pulmonary function test. If tracheal stenosis is detected, treatment according to currently available guidelines will be performed. Patients with no signs of clinical, functional and radiological evidence of tracheal stenosis will perform a 3 and 6 months clinical follow-up from initial evaluation. A chest CT scan with pulmonary function test will be administered if symptoms of tracheal stenosis arise during clinical follow-up. If necessary, treatment according to currently available guidelines will be performed. Patients will be followed-up for 8 months after hospital discharge.

OBSERVATIONAL

Patients will perform an initial evaluation at 2 months from hospital discharge using a chest CT scan without contrast-enhancing along with a pulmonary function test using spirometry. Based on results and according to current guidelines, further follow-up or intervention will be administered.

RECRUITINGIncidence of tracheal stenosis following either prolonged intubation or tracheostomy in COVID-19 patients
Observe how many subject in the population at risk will develop tracheal stenosis during follow-up
Time frame: 8 months
Clinical presentation of tracheal stenosis
Describe symptoms most commonly associated with tracheal stenosis
Time frame: 8 months
Clinical course of tracheal stenosis
Analyse the clinical evolution of tracheal stenosis during follow-up
Time frame: 8 months
Outcome of tracheal stenosis
Collect data on morbidity and mortality of tracheal stenosis
Time frame: 8 months
Identification of demographic factor with a predictive and prognostic value for tracheal stenosis
Patient's characteristic (e.g. sex, age, weight and height) will be collected during follow-up to search for any statistically significant association with risk of developing tracheal stenosis or disease-free survival
Time frame: 8 months
Identification of clinical factor with a predictive and prognostic value for tracheal stenosis
Information regarding hospitalisation (e.g. personal history of diabetes, chronic obstructive pulmonary disease, previous prolonged intubation or tracheostomy) will be collected during follow-up to search for any statistically significant association with risk of developing tracheal stenosis or disease-free survival
Time frame: 8 months
Identification of radiological factor with a predictive and prognostic value for tracheal stenosis

Data collected from CT scan performed during follow-up (e.g. distance of stenosis from vocal chords, length and diameter) will be collected during follow-up to search for any statistically significant association with risk of developing tracheal stenosis or disease-free survival
Time frame: 8 months
Identification of instrumental factor with a predictive and prognostic value for tracheal stenosis
Results obtained from pulmonary function test (e.g. forced expiratory volume at one second, forced vital capacity and peak expiratory flow rate) will be collected during follow-up to search for any statistically significant association with risk of developing tracheal stenosis or disease-free survival
Time frame: 8 months
Compare COVID-19 and non-COVID-19 patients at risk of developing tracheal stenosis
A control-group of patient who underwent either prolonged intubation or tracheostomy without diagnosis of COVID-19 will be used as comparison to search for any difference in primary and secondary outcome
Time frame: 8 months
