Brief Summary:
This multicentric prospective clinical practice study aims at evaluating clinical factors associated with a prolonged invasive mechanical ventilation and other outcomes such as mortality and ICU length of stay in patients affected from COVID-19 related pneumonia and ARDS.

Condition or disease Intervention/treatment

Study Type : Observational
Estimated Enrollment : 600 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Risk Factors for Prolonged Invasive Mechanical Ventilation in COVID-19 Acute Respiratory Distress Syndrome
Actual Study Start Date : February 1, 2020
Actual Primary Completion Date : June 30, 2020
Estimated Study Completion Date : October 30, 2020

Group/Cohort Intervention/treatment
COVID-19 pneumonia patients
Patients needing intubation and mechanical ventilation for COVID-19 related pneumonia without other primary causes of ICU admission
Other: Invasive mechanical ventilation
Invasive mechanical ventilation for respiratory failure associated to COVID-19 pneumonia

Primary Outcome Measures :
  1. Duration of mechanical ventilation and 28 days ventilator free days [ Time Frame: 28 days ]

    Ventilator free days (VFDs) will be calculated in a time frame of 28 days, the beginning of observation will coincide with the day of intubation and observation will end after successful disconnection from mechanical ventilation.

    For intubated patients, post extubation non invasive ventilation (NIV) will not be accounted as a ventilation period, in case of interval reintubation within 28 days, VFDs will be counted from the last successful extubation.

    For tracheostomized patients, ventilator free days will be counted after successful disconnection from mechanical ventilation and interval reconnections will be considered in the ventilation interval as for intubated patients.

Secondary Outcome Measures :
  1. ICU Mortality [ Time Frame: 60 days ]
  2. 30 days survival after ICU discharge [ Time Frame: 30 days ]
  3. 90 days survival after ICU discharge [ Time Frame: 90 days ]
  4. Quality of life at 90 days after ICU discharge measured with 15D instrument [ Time Frame: 90 days ]

    15D instrument ( will be administered via telephonic interview


  5. Radiologic aspects - structured description of CT and RX data [ Time Frame: 90 days ]

    First available CT, last CT before ICU admission and intubation, last ICU follow-up CT. First available chest X ray, last chest X ray before ICU admission and intubation, last ICU- follow up chest X ray and 30 days follow-up CT (if available) will be evaluated, if available.

    Structured description

    CT scan

    Date: yyyy/mm/dd Parenchymal alterations: ground glass, crazy paving, parenchymal consolidation Extension: monolateral, bilateral Number of lobes involved: (1-5) Percentage of parenchymal involvement: 0-100% Distribution: subpleural, random, diffuse

    X-ray scan

    Date: yyyy/mm/dd Main aspects: normal, focal lesions, monolateral multifocal lesions (right/left), diffuse multifocal lesions Lesion aspects: interstitial, interstitial/alveolar, alveolar, consolidations Pleural effusion presence and entity

    Pulmonary involvement score:

    0 = no involvement

    1. =< 25%
    2. = 25-50% 3= 50-75%

    4 => 75% Total score (0-6): score of the right lung + score of the left lung

Study Population
This study enrolls patients admitted to ICU needing intubation and mechanical ventilation bacause of respiratory failure for COVID-19 pneumonia without other primary causes for ICU admission

Inclusion Criteria:

  • Age ≥ 18 years
  • ICU admission because of the need of mechanical ventilation in the context of COVID-19 related pneumonia (swab proven)

Exclusion Criteria:

  • COVID-19 related pneumonia complicating the clinical course of patients admitted to the ICU for another reason (e.g. trauma, stroke)
