Eligibility
Inclusion criteria
Inclusion criteria: The population included will be hospitalized patients with confirmed COVID-19, = 18 years old with isolated severe hypoxic respiratory failure defined as: SpO2 30/min despite treatment with at least 6 L/min oxygen therapy on nasal cannula. These patients may be included at the pulmonary departments delivering COVID-19 care, intensive care units or directly on the Emergency department. SARS-CoV-2 negative patients (nasopharyngeal PCR) will be excluded for this analysis, retrospectively. Inclusion criteria In order to be eligible to participate in this study, a subject must meet all of the following inclusion criteria: ? Age = 18 years ? Admitted to the hospital ? Suspect of COVID-19 or nasopharyngeal swab PCR confirmed COVID-19 ? SpO2 30/min despite at least 6L O2/min on nasal cannula.
Exclusion criteria
Exclusion criteria: A potential subject who meets any of the following criteria will be excluded from participation in this study: ? Reasons for direct intubation, as per local standard of clinical care. ? Patient does not accept treatment with HFNC ? Anatomic abnormalities (recent surgery of the face, nose, or airway) that preclude an appropriate-fitting nasal cannula
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary study endpoint is HFNC failure. HFNC failure is defined as: ? Patients without a DNI policy: Intubation. or ? Patients with DNI policy: Persistent hypoxemia, defined as SpO2 < 90% despite a maximum FiO2 (>90%) and flow (>50L/min) and/or death because of terminal respiratory failure. | — |
Secondary
| Measure | Time frame |
|---|---|
| Feasibility of HFNC > Proportion of non-ICU admitted HFNC patients requiring ICU admission > Proportion of HFNC patients requiring NIV (CPAP or BiPAP) > Duration of HFNC therapy (ward vs ICU) To identify risk factors associated with treatment failure of HFNC (baseline risk factors or time-dependent/treatment-related risk factors) To determine the long-term consequences of the use of HFNC therapy on physical activity level, persisting symptoms and health-related quality of life in severe COVID-19 patients who were treated with HFNC. Tertiary outcome* To determine the evolution of the ROX index in severe hypoxic COVID-19 patients during HFNC treatment. To compare primary and secondary endpoints between subgroups of patients such as: a. Early HFNC start (defined as: maximum 6L O2/min) vs. late (defined as: more than 6L O2/min). b. Start HFNC with low or high ROX index c. Start HFNC on ward vs. ICU d. Start HFNC with a flow of 40L/min vs. flow > 40L/min e. Centers with HFNC only in ICU vs. Center with HFNC in ward and ICU Longer duration of HFNC therapy is associated with persistent long-term symptoms and poorer long-term outcomes on quality of life and physical performance . | — |
