Background:
COVID-19 nosocomial transmission puts patients with different medical conditions at risk for severe illness and death. The general purpose of this study is to estimate the prevalence of nosocomial COVID-19 cases among hospitalized patients with COVID-19 disease.
Methods:Cross-sectional study of 4.293 COVID-19 hospitalized patients in Hospital Universitario Virgen de la Victoria of Málaga, between 01/08/2020 and 31/01/2021.
The following variables were described: date of admission, PCR performed, presence and type of symptomatology and IgG result.
Nosocomial case was defined as being diagnosed after at 48 hours since date of admission, not manifesting COVID-19 compatible symptoms within this period, as well as not having positive IgG within 7 days since date of admission. Definitions from Andalusian Society of Preventive Medicine were used.
COVID-19 disease was established when a positive result of antigen/PCR was obtained.
Information was taken from Hospital Databases, and was studied using an Open Source Office Spreadsheet and RStudio software 3.6.3.
Results:Among the 4.293 hospitalized patients with COVID-19 disease, 85 were diagnosed of COVID-19 disease after admission. Only 25 met nosocomial case criteria, representing a prevalence of 0,58%. 7 (28%) were classified as indeterminate; 7 (28%) as probable cases; and 11 (44%) as definitive cases.
24 cases (96%) had at least one previous negative PCR during the hospitalization before the diagnosis of COVID-19 disease. Only 3 (12%) remained asymptomatic during the whole hospitalization. No secondary cases were observed.
Time from date admission to COVID-19 diagnosis had a median of 11.11 days.
Traceability was performed in order to investigate the infection origin. Only in 3 cases (12%) the origin was determined and associated to family visitors.
Conclusions:Epidemiological and microbiological surveillance is substantial to prevent SARS-CoV-2 spread in hospitals. Although present, the nosocomial cases of COVID-19 didn’t represent substantial percentage of COVID-19 cases. Nonetheless, it is necessary to establish means to prevent their appearance and detect them early as they may generate outbreaks with fatal consequences. Antigen/PCR screening on admission, restriction of visits and the generalised use of face masks by the patients and their family was introduced in our centre during the study period.
