Trial summary

Hospital mortality attributed to SARS-CoV-2 in France increased daily by 28% in the week before confinement. The week following this decision, the daily increase was 30%. During the week of the second week of confinement, it started a decline of 19% estimated over the last 5 days, reaching the cumulative number of… Read more about this study

About this study

Hospital mortality attributed to SARS-CoV-2 in France increased daily by 28% in the week before confinement. The week following this decision, the daily increase was 30%. During the week of the second week of confinement, it started a decline of 19% estimated over the last 5 days, reaching the cumulative number of 2606 deaths on 29/3 (site https://www.eficiens.com/coronavirus- personal statistics / and calculation).

The diagnosis of viral carriage by RT-PCR is reserved for symptomatic cases among caregivers, due to the shortage of available tests and the cumbersome implementation. The carrier diagnosis is the benchmark, on which are implemented the therapeutic strategies and established the national statistics. It can present false negatives, linked to a research too early or too late in relation to the infection, or to a technical defect of the nasal swab sample. Caregivers on the front line in patient care, in hospitals or in the city, have only partial access to this diagnostic test, depending on the existence of symptoms. The implementation of a systematic serological screening, planned by the government and which cannot be based only on the search for the virus, will make it possible to inform the caregivers presenting symptoms or not, of their serological status, and therefore of their degree immunity or, on the contrary, susceptibility to infectious contacts. It should therefore be very voluntarily requested. On the occasion of this screening, the constitution of the COVID-3S cohort will make it possible to verify the degree of contamination in an asymptomatic population, information which is sorely lacking for the estimation of the immune coverage of the population. The implementation of the Covid-3S study will be based on the work of the National Reference Center of Pr B Lina, from the COVID-SER cohort, for the selection of the most efficient test (s). It seems useful to initiate the constitution of this cohort as soon as possible in relation to the evolution of the epidemic. Pending receipt of official recommendations, the lack of knowledge of the performance of serological tests means that it should be applied first to health professionals, better able to appreciate its limits, for the initial period before determining a validated serological screening strategy. Once the strategy has been specified, the gradual expansion of screening to the patient population will provide a more representative basis for the construction of epidemiological models for evaluating strategies.

Questions about this trial

What is this clinical trial studying?

An observational study of COVID, run by Hospices Civils de Lyon at 4 sites in France.

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 2 inclusion and 2 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 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in France. 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.

Are results available for this study?

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?

Establishment of a reliable prediction model for the effectiveness of virus control (time frame: 18 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 Feb 2023.
