Hospital-acquired COVID-19 affects patients and workers, study finds

While the absolute risk of contracting COVID-19 in hospital was low – up to a 0.75% risk per day of exposure to the pre-Delta variant (B1617.2) – patients or workers at health (HS) affected by COVID-19 may nonetheless be factors in the spread of COVID-19, a study published yesterday in PLOS A said.

Researchers looked at four UK university hospitals, where 66,184 patients were hospitalized and 5,569 healthcare workers were on duty from January 12 to October 2, 2020. Of the patients, 1.4% tested positive within the same period, and 10.5% of them. (97) had their first positive test after hospitalization at least 7 days after admission, where they were considered a nosocomial case. Patients who likely contracted COVID-19 infections during their hospital stay were older, had longer lengths of stay and had more readmissions, the researchers note.

Among healthcare workers, 11.0% tested positive during the study period.

For susceptible patients, 1 day in the same ward with a patient with nosocomial COVID-19 infection was associated with 7.5 additional infections per 1,000 susceptible patients per day (95% credibility interval [CrI], 5.5 to 9.5). Exposure to an infectious patient with community-acquired COVID-19 or an infectious healthcare worker, on the other hand, was associated with 2.0 additional infections per 1,000 susceptible patients per day (95% CrI, 1.6 to 2.2).

Healthcare worker infections acquired from patients or another healthcare worker were both associated with 0.8 additional infections per 1,000 susceptible healthcare workers per day (95% ICr, 0.3 to 1.6 and 0.6 to 1.0, respectively). Exposure to an infectious patient with community-acquired COVID-19 infection was associated with an additional infection of 0.2 per 1,000 susceptible TS per day (95% ICr, 0.2 to 0, 2).

“In this study, we observed that the exposure of patients with nosocomial SARS-CoV-2 is associated with a substantial risk of infection for healthcare workers and other hospitalized patients. Infection control measures to limit nosocomial transmission must be optimized to protect both staff and patients infected with SARS-CoV-2, ”the researchers write, noting that increased mitigation measures from April 25 2020 were associated with a 75% reduction in the risk of infection in susceptible patients.

About 3 in 20 Midwestern healthcare workers are hesitant about COVID vaccine

In a survey of 1,971 people from March to May, about 3 in 20 Midwestern healthcare workers were hesitant about the COVID-19 vaccine, according to a study published yesterday in the American Journal of Infection Control.

Respondents were from a 465-bed University of Illinois hospital in Chicago, a 664-bed Rush University Medical Center hospital, and a system of 26 hospitals in Wisconsin and Illinois led by lawyer Aurora. The survey, which was based on the Health Belief Model framework, showed that 15% of healthcare workers had not received or were not planning to receive a COVID-19 vaccine. .

Overall, vaccinated HCWs were more likely than unvaccinated HCWs to be influenced by having close contacts who wanted them vaccinated (odds ratio [OR], 5.52 to 18.83, depending on the relationship). They were also more likely to believe that vaccination would reduce the spread of COVID-19 (OR, 51,49) and reduce the likelihood that they, their patients and their families would be infected (OR, 28,22, 22, 45 and 27.19, respectively).

Unvaccinated people, in comparison, were 93% more likely to believe the vaccine did not have enough evidence. They were also more likely to be black (OR, 0.34), Republicans (OR, 0.54), allergic to any component of the vaccine (OR, 0.27), or to think it would negatively affect pregnancy or pregnancy planning (OR, 0.09), based on multivariate logistic regression that led to a vaccine reluctance model that is 95% accurate.

Researchers noted that vaccinated people were more likely to be persuaded to be accepted by external stimuli (p.

“Rather than focusing on pervasive, impersonal awareness-raising advertisements from a hospital administration or mainstream media,” they conclude, “hospitals should work internally to foster relationships and build trust among patients. employees in all departments and positions, especially among nurses and physicians who remain highly trusted in their communities.
