Predictors of Non-invasive Respiratory Support Failure in COVID-19 Pneumonia — RUTIROX  

Covid19 Clinical Trial

Official title: Predictors of Non-invasive Respiratory Support Failure in COVID-19 Pneumonia

Status Completed

Clinical Trial Summary

The main objective of the current study is to search predictors of non-invasive respiratory support failure, like high -flow oxygen system (HFO) and pressure systems, Bilevel positive airway pressure (BiPAP) and continuous positive airway pressure (CPAP), in patients with acute hypoxemia produced by COVID-19 pneumonia. In the first phase, we will do a retrospective review of the intermediate respiratory care unit activity from March to May 2020 in the target population. In the second phase development an interventional study. At admission all patients will be treated with HFS monitoring clinical variables like respiratory frequency, oxygen saturation, gasometer results and oxygen inspiration fraction. In case of HFO failure, the patients will be randomized to treatment with CPAP or BIPAP. The same clinical variables will be monitoring to analysis their prediction capacity of failure therapy, defined as mortality or need to intubation. The results will be adjusted comorbidity grade, age and initial severity pneumonia. Secondary objectives of study are 90 days mortality, functional recovery at 90 days and to realise a cost-effectiveness valuation of non-invasive respiratory supports in this disease.

Clinical Trial Description

The purpose of the study Pneumonia caused by the SARS Cov-2 coronavirus is a viral infectious disease that is characterized in some cases by the rapid and progressive respiratory failure of the respiratory system, being the most serious affectation and the one that marks the prognosis. Non-invasive breathing supports are therapies that help you breathe in severe respiratory failure. Therefore, monitoring of respiratory exhaustion should be carried out in all patients with SARS Cov-2 pneumonia. Within this follow-up, prognostic factors could be identified that help to assess with what probability the treatment with these supports may or may not be successful. We will carry out a prospective, descriptive study at this center in order to assess respiratory clinical variables by telemetry recording and blood tests during follow-up. To do this, we will carry out, during the follow-up of patients already diagnosed, or with a new diagnosis of SARS Cov-2 pneumonia and respiratory failure, who require non-invasive support therapy, an analysis on the first day of initiation of therapy, at 48 hours and at the end of this therapy, we will also continuously monitor vital signs while these therapies are used. We will compare the values obtained from patients who only require therapy with high-flow nasal cannulas and from patients who are not sufficient for this treatment and need non-invasive mechanical ventilation. Participants in this study who do not have sufficient respiratory support with high-flow cannula therapy and feel exhausted, will be switched to non-invasive mechanical ventilation. Each patient will be randomly assigned to one of two possible settings: setting A (continuous pressure mechanical ventilation) or setting B (intermittent pressure mechanical ventilation). This decision is made because to date there are no scientifically proven differences in which configuration is best for the treatment of this disease. The data on the success of the therapies will be compared, understanding as failure the need for orotracheal intubation to perform invasive mechanical ventilation or death. This research study has been approved by the Research Ethics Committee of the Germans Trias i Pujol University Hospital. Study Procedures and Possible Risks and Discomforts Vital signs will be recorded during the time that non-invasive respiratory support therapy is performed continuously for the assessment of respiratory status. This does not pose any additional risk, since it is a non-invasive procedure and without exposure to ionizing radiation. Between 3 and 5 tests will be carried out during the study, which are the same as those carried out in the usual clinical practice of this disease. They pose risks of pain due to puncture and extravasation of a blood vessel. Participation in this study would not produce any discomfort except those derived from the non-invasive respiratory support therapies themselves. These are: epistaxis, runny nose, excessive noise in the treatment with high-flow cannulas and skin ulcers in the case of non-invasive mechanical ventilation. It does not imply an added risk to that of normal clinical practice for health since an additional intervention will not be carried out. The information regarding your personal data (initials and medical record number) will be coded, a non-consecutive alphanumeric code will be assigned, which will be called the patient study code. This will only be known to the principal investigators, who will save this data using a password-protected Microsoft Excel file. The clinical information collected for the study associated with your patient code will be stored in a Microsoft Excel type computer file located at the research center. The REDCAP form will be used for data collection. To access it, you will need a second password different from the first one. These data can only be re-identified by the study's principal investigators or by collaborators authorized by them. They will be used exclusively for the purposes specified here. Voluntary participation and withdrawal You can freely decide whether or not you want to take part in this study, participation is completely voluntary. If you decide to participate, you still have the possibility to withdraw at any time, without having to give explanations, and without any penalty or negative consequences for you. If you change your mind regarding your samples or your data, you have the right to request their destruction or destruction. anonymization, through your doctor / researcher. However, you should know that the data obtained in the analyzes carried out up to that moment may be used for the purposes requested and may be kept in compliance with the corresponding legal obligations. Participation in this study is not incompatible with participation in other clinical studies or trials. Possible benefits No direct benefit is expected from your participation in the study. However, the information gained from this research project can contribute to medical advancement and could help other patients in the future. You will not receive any economic benefit for the transfer of the data provided, nor will you have rights over possible commercial benefits of the discoveries that may be achieved as a result of the research carried out. Data protection and confidentiality All information about your results will be treated strictly confidential. Your personal data will be identified by a code, so that it does not include information that can identify you, and only the research team will be able to relate that data to you. These data will be protected by password. These coded clinical data will be the ones that will be statistically analyzed to search for scientific findings that answer the questions proposed in this study. The analysis of this data will be carried out by the external company BUTLER SCIENTIFICS using Auto-discovery technology. This has signed a confidentiality and data treatment contract with the promoting center and the study researchers. This company will receive the data by means of a file with a password via email from the promoter center. BUTLER SCIENTIFCS in no case will know identifying data of the study participants.
