SARS CoV 2 Infection
Conditions
Brief summary
The rate of nosocomial SARS-CoV2 infections found in the different studies since the beginning of the pandemic is very variable (\<1% in hospitals in the USA to about 20% in a British hospital). Mortality related to these nosocomial SARS-CoV2 infections is higher than in the general population. The risk factors identified for this nosocomial acquisition are multiple. We were confronted with nosocomial acquisitions and cluster situations in the services, without exhaustive data to measure these phenomena, and we lacked data to consider areas for improvement. The objectives of this study are to determine the proportion of nosocomial SARS COV 2 infections in the total number of patients hospitalized with a Covid-19 infection at the CHR Metz-Thionville in 2021, and to describe the characteristics of this population.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of hospital-acquired infections in patients hospitalised with a covid-19 infection | up to 8 months after the third COVID-19 wave | Several elements are taken into account: a) the time between entry into the establishment and the first positive SARS COV 2 PCR, b) the time between entry into the establishment and the appearance of the most frequent symptoms (fever, cough), if present in the patient, in the seven days preceding the first positive SARS COV 2 PCR, c) the existence of an epidemiological link with other infected patients, via contact in a double room with another case, and/or via hospitalisation in a department concerned by a cluster situation according to the Santé Publique France definition of May 2020 (identified on the basis of monitoring and surveillance data from the hygiene department). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Description of the nosocomial infected population | up to 8 months after the third COVID-19 wave | age, sex, hospital unit care, outcomes of stay, vaccination status, associated conditions (comorbidities according to Charlson score, obesity, pregnancy), existence of screening on admission, time to acquisition of nosocomial infection, number of negative SARS-COV 2 PCRs in the institution before the first positive PCR, type of variant, presence of symptoms (cough, fever), stay in a double room in the 14 days prior to infection, cluster status in the ward, length of stay after infection. |
