Automated surveillance of healthcare-associated infections using an artificial intelligence algorithm.
Healthcare-associated infections (HAIs) are among hospitals' most common adverse events. In a cohort study, we used artificial intelligence (AI) algorithms for infection surveillance. The model correctly detected 67 out of 73 patients with IAHs. The final model reached an area under the receiver operation curve (ROC-AUC) of 90.27%; specificity of 78.86%; sensitivity of 88.57%. Respiratory infections had the best results (ROC-AUC ≥93.47%).

Coronavirus Disease 2019 (Covid-19): Transmission events in school professionals: a Brazilian prospective cohort.
From October to December 2020, we followed a prospective cohort of 315 professionals and 768 students from three schools in Porto Alegre and the metropolitan region regarding the transmission of Sars-Cov-2. In the period, schools were in hybrid mode (with students in person and at a distance). The schools have gone through a process of reviewing their protocols. Through the robot-ISA application, professionals and students were monitored for the presence of symptoms. Professionals who had symptoms were evaluated on the same day by an infectious diseases physician. There were 3,229 responses from professionals to the ISA robot. Fifty-five professionals reported symptoms. Of these, seven professionals (2.2% of the total) were positive. The presence of fever, tiredness and more than five symptoms correlated with positivity for Sars-cov-2. There was no work-related transmission event among school professionals.

Management of antimicrobials by telemedicine in a community hospital in southern Brazil
The tele-stewardship program was implemented in a 50-bed community hospital 575 km away. The intervention began in May 2011. During the four months, 81 prescription evaluations were carried out. The rate of the adequacy of prescriptions rose from 36% to 60% in the fourth month of work. Adherence to the recommendations of specialists by remote medical professionals was 100%. The study showed that telemedicine tools could be applied over long distances, with excellent adherence, in community hospitals in Brazil, where access to specialists is more complicated.

Intervention study before and after Qualis services at the Alto Vale Regional Hospital
From May 2014 to April 2016, a quasi-experimental study in a 220-bed hospital showed that a tele-stewardship intervention reduced the consumption of antimicrobials such as quinolones, first-generation cephalosporins, vancomycin, and polymyxins. On the other hand, it increased the consumption of amoxicillin+clavulanate and cefuroxime. The adequacy of choices for antimicrobials rose from 51% to 84%, which significantly impacted the reduction of bacterial resistance, especially Carbapenem-resistant Acinetobacter spp.. In addition, there was a reduction in antimicrobial spending in the order of R$109,730.00 (monthly average) before to R$ 89,723.00 (savings of 20 thousand reais monthly).
