Background and objective:
The large-scale introduction of anti-COVID vaccination has been shown to reduce the probability of contracting and spreading the infection by the vaccinated person. The diagnostic capacity of the nasopharyngeal swab for COVID+ is limited at the time of its execution, failing to identify subjects who are in the incubation period and therefore with limited efficacy in preventive identification at the time of hospitalization. To limit the development of intra-hospital clusters of COVID+, a bed management model was structured based on the vaccination status recorded in the electronic medical record and on the length of hospitalization.

Starting from April 2021, the vaccination status for all hospitalizations, recorded on electronic health records, was extracted in daily reports provided to bed management. The bed management model used provided for the prohibition of sharing the hospital room between unvaccinated subjects or the possible association of long-term patients.

The incidence of clusters (more than two cases in 7 days per unit of stay) in the hospital in the quarter following the implementation of this model showed a percentage reduction of 72.5%.

optimal management of patient placement in small cohorts according to public health criteria can help reduce the occurrence of infectious complications
