Nosocomial COVID-19 Infections in Patients Hospitalized at the Metz-Thionville Regional Hospital in 2021

Proportion of Nosocomial COVID-19 Infections in Patients Hospitalized at the Metz-Thionville Regional Hospital in 2021

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.

Inclusion Criteria:

• Patients hospitalised at the CHR Metz-Thionville in medicine, surgery and obstetrics (MCO) or geriatric follow-up and rehabilitation care (SSR) units, in 2021 for a Covid-19 infection defined by the existence of a positive PCR result for SARS-CoV2 during the stay, or by the existence of an ICD10 code for COVID in the PMSI data of the health care establishment

Exclusion Criteria:

• Opposition to participate in the study after reading the patient information note.
