RESUMO
AIMS: To investigate the genetic profile and characterize antimicrobial resistance, including the main ß-lactam antibiotic resistance genes, in Acinetobacterbaumannii isolates from a tertiary hospital in Recife-PE, Brazil, in the post-COVID-19 pandemic period. METHODS AND RESULTS: Acinetobacter baumannii isolates were collected between 2023 and 2024 from diverse clinical samples. Antimicrobial resistance testing followed standardized protocols, with ß-lactamase-encoding genes detected via PCR and sequencing. Investigation into ISAba1 upstream of blaOXA-carbapenemase and blaADC genes was also conducted. Genetic diversity was assessed through ERIC-PCR. Among the 78 A. baumannii, widespread resistance to multiple antimicrobials was evident. Various acquired ß-lactamase-encoding genes (blaOXA-23,-24,-58,-143, blaVIM, and blaNDM) were detected. Furthermore, this is the first report of blaVIM-2 in A. baumannii isolates harboring either the blaOXA-23-like or the blaOXA-143 gene in Brazil. Molecular typing revealed a high genetic heterogeneity among the isolates, and multi-clonal dissemination. CONCLUSION: The accumulation of genetic resistance determinants underscores the necessity for stringent infection control measures and robust antimicrobial stewardship programs to curb multidrug-resistant strains.

BACKGROUND: Hand hygiene (HH) is an important strategy for preventing health-care-associated infections (HAIs). Few programs focus on HH for family members and primary caregivers but fewer for patients. This study aimed to estimate the frequency with which hospitalized pediatric patients have hand contact with hospital surfaces. METHODS: We conducted a cross-sectional descriptive observational study consisting of three phases: the first was the creation of an observation and data collection tool, the second was the training of the monitors, and the third was the observational study of hand contact and HH opportunities in hospitalized pediatric patients. RESULTS: Over 3600 minutes of observation, 2032 HH opportunities were detected, averaging 33.8/h (SD 4.7) as determined by hand contact with hospital surfaces of hospitalized pediatric patients. In our study, infants and preschool children had the highest frequency of hand contact. CONCLUSION: The high frequency of hand contact of hospital surfaces by children suggests that hourly hand disinfection of patients and caregivers, objects and surfaces around the patients may be prevention measures that could be incorporated to reduce HAIs in pediatric hospitals.
INTRODUCCIÓN: La higiene de manos es una estrategia importante para la prevención de infecciones asociadas a la atención sanitaria. Existen pocos programas centrados en la higiene de manos para los familiares y cuidadores primarios, y aún menos para el paciente. El objetivo de este estudio fue cuantificar la frecuencia con la que los pacientes pediátricos hospitalizados tienen contacto manual con superficies hospitalarias. MÉTODOS: Se llevó a cabo un estudio observacional descriptivo transversal que constó de tres fases: la primera fue la creación de una herramienta de observación y registro de datos; la segunda fue la capacitación de los monitores y la tercera fue el estudio observacional del contacto manual y de las oportunidades de higiene de manos en pacientes pediátricos hospitalizados. RESULTADOS: Durante los 3600 minutos de observación, se detectaron 2032 oportunidades, con una media de 33.8 (DE 4.7) por hora de oportunidades de higiene de manos establecidas por contacto manual con superficies de pacientes pediátricos hospitalizados. Los lactantes y los niños en edad preescolar presentaron la mayor frecuencia de contacto manual. CONCLUSIONES: La alta frecuencia de contacto manual por parte del niño indica que medidas como la desinfección de las manos cada hora del paciente y del cuidador, así como de los objetos y superficies alrededor del paciente, podrían ser medidas útiles que deberían incluirse para prevenir las infecciones asociadas a la atención de la salud en los hospitales pediátricos.

RESUMO
Recognition of risk factors for hospital-acquired infections (HAI) in patients with COVID-19 is warranted. We aimed to describe factors associated with the development of HAI in patients with severe COVID-19. We conducted a retrospective cohort study including all adult patients admitted with severe COVID-19 between March 2020 and November 2020. The primary outcome was HAI development. Bivariate and multiple logistic regression models were constructed. Among 1540 patients, HAI occurred in 221 (14%). A total of 299 episodes of HAI were registered. The most common HAI were hospital-acquired/ventilation-associated pneumonia (173 episodes) and primary bloodstream infection (66 episodes). Death occurred in 387 (35%) patients and was more frequent in patients with HAI (38% vs. 23%, p < 0.01). Early mechanical ventilation (aOR 18.78, 95% CI 12.56-28.07), chronic kidney disease (aOR 3.41, 95% CI 1.4-8.27), use of corticosteroids (aOR 2.95, 95% CI 1.92-4.53) and tocilizumab (aOR 2.68, 95% CI 1.38-5.22), age ≥ 60 years (aOR 1.91, 95% CI 1.27-2.88), male sex (aOR 1.52, 95% CI 1.03-2.24), and obesity (aOR 1.49, 95% CI 1.03-2.15) were associated with HAI. In patients with severe COVID-19, mechanical ventilation within the first 24 h upon admission, chronic kidney disease, use of corticosteroids, use of tocilizumab, age ≥ 60 years, male sex, and obesity were associated with a higher risk of HAI.
RESUMO
Objective: This study aimed to determine the performance of infection prevention and control (IPC) programs in eight core components in level 2 and level 3 hospitals across all provinces in Colombia. Methods: This cross-sectional study used self-assessed IPC performance data voluntarily reported by hospitals to the Ministry of Health and Social Protection during 2021. Each of the eight core components of the World Health Organization's checklist in the Infection Prevention and Control Assessment Framework contributes a maximum score of 100, and the overall IPC performance score is the sum of these component scores. IPC performance is graded according to the overall score as inadequate (0-200), basic (201-400), intermediate (401-600) or advanced (601-800). Results: Of the 441 level 2 and level 3 hospitals, 267 (61%) reported their IPC performance. The median (interquartile range [IQR]) overall IPC score was 672 (IQR: 578-715). Of the 267 hospitals reporting, 187 (70%) achieved an advanced level of IPC. The median overall IPC score was significantly higher in private hospitals (690, IQR: 598-725) than in public hospitals (629, IQR: 538-683) (P < 0.001). Among the core components, scores were highest for the category assessing IPC guidelines (median score: 97.5) and lowest for the category assessing workload, staffing and bed occupancy (median score: 70). Median overall IPC scores varied across the provinces (P < 0.001). Conclusions: This countrywide assessment showed that 70% of surveyed hospitals achieved a self-reported advanced level of IPC performance, which reflects progress in building health system resilience. Since only 61% of eligible hospitals participated, an important next step is to ensure the participation of all hospitals in future assessments.

RESUMEN Objetivo. El objetivo de este estudio es determinar el desempeño de los programas de prevención y control de infecciones (PCI) en relación con ocho componentes básicos en hospitales de nivel 2 y 3 de todas las provincias de Colombia. Métodos. En este estudio transversal se emplearon datos de autoevaluación del desempeño de los programas de PCI informados voluntariamente al Ministerio de Salud y Protección Social por parte de los hospitales durante el 2021. Cada uno de los ocho componentes básicos de la lista de verificación de la Organización Mundial de la Salud incluidos en el Marco de evaluación de prevención y control de infecciones al nivel de establecimientos de atención de salud recibe una puntuación máxima de 100, y la puntuación general del desempeño del programa es la suma de las puntuaciones de estos componentes. Este desempeño se califica según la puntuación general como inadecuado (0-200), básico (201-400), intermedio (401-600) o avanzado (601-800). Resultados. De los 441 hospitales de nivel 2 y nivel 3, 267 (61%) informaron datos sobre su desempeño. La mediana (rango intercuartil [IQR]) de la puntuación general fue de 672 (IQR: 578-715). De los 267 hospitales que proporcionaron información, 187 (70%) alcanzaron el nivel avanzado. La mediana de la puntuación general fue significativamente mayor en los hospitales privados (690, IQR: 598-725) que en los hospitales públicos (629, IQR: 538-683) (p < 0,001). En el caso de los componentes básicos, las puntuaciones más altas fueron para la categoría que evalúa las directrices de PCI (puntuación mediana: 97,5) y más bajas para la categoría que evalúa la carga de trabajo, la dotación de personal y la ocupación de camas (puntuación mediana: 70). La mediana de las puntuaciones generales de PCI varió entre las provincias (p < 0,001). Conclusiones. Esta evaluación a nivel nacional mostró que el 70% de los hospitales encuestados lograron un nivel avanzado autoinformado del desempeño en cuanto a la PCI, lo que refleja el progreso en fortalecimiento de la resiliencia del sistema de salud. Dado que solo participó el 61% de los hospitales que reunían las condiciones, el siguiente paso importante es garantizar la participación de todos los hospitales en futuras evaluaciones.
RESUMO Objetivo. Este estudo teve o objetivo de determinar o desempenho de programas de prevenção e controle de infecções (PCI) quanto a oito componentes centrais em hospitais secundários e terciários de todas as províncias da Colômbia. Métodos. Este estudo transversal utilizou dados de desempenho autoavaliado de PCI enviados voluntariamente pelos hospitais ao Ministério da Saúde e Proteção Social em 2021. Cada um dos oito componentes centrais da lista de verificação na Estrutura de Avaliação de Prevenção e Controle de Infecções da Organização Mundial da Saúde contribui com uma pontuação máxima de 100. A pontuação total de desempenho de PCI é a soma das pontuações nesses componentes. De acordo com a pontuação total, o desempenho de PCI é classificado nas seguintes categorias: inadequado (0-200), básico (201-400), intermediário (401-600) ou avançado (601-800). Resultados. Dos 441 hospitais secundários e terciários, 267 (61%) informaram o desempenho de PCI. A mediana (intervalo interquartil [IIQ]) da pontuação total de PCI foi 672 (IIQ: 578-715). Dos 267 hospitais que disponibilizaram informações, 187 (70%) alcançaram um nível de PCI avançado. A mediana da pontuação total de PCI foi significativamente maior nos hospitais privados (690, IIQ: 598-725) do que nos públicos (629, IIQ: 538-683) (p < 0,001). Entre os componentes centrais, as pontuações mais altas foram observadas na categoria de avaliação das diretrizes de PCI (pontuação mediana: 97,5), ao passo que as mais baixas ocorreram na categoria de avaliação da carga de trabalho, dotação de pessoal e taxa de ocupação de leitos (pontuação mediana: 70). As medianas das pontuações totais de PCI variaram entre províncias (p < 0,001). Conclusões. Esta avaliação nacional mostrou que 70% dos hospitais pesquisados alcançaram um nível avançado de desempenho autorrelatado de PCI, o que demonstra progresso no desenvolvimento de resiliência no sistema de saúde. Como apenas 61% dos hospitais elegíveis participaram, um próximo passo importante é assegurar a participação de todos os hospitais em futuras avaliações.
RESUMO
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a public health emergency, as it is a highly contagious disease, health services had to adapt to the high demand for hospitalizations in order to contain hospital outbreaks. We aimed to identify the impact of nosocomial transmission of severe acute respiratory coronavirus virus 2 among inpatients at a university hospital in São Paulo, Brazil. Among 455 inpatients diagnosed with coronavirus disease 2019 in March-May, 2020, nosocomial infection was implicated in 42 (9.2%), of whom 23 (54.7%) died. becoming routine, especially when community transmission occur with high levels of incidence. It was possible to observe with this study that the nosocomial transmission by SARS-CoV-2 was present even with these measures instituted, and some of the damages caused by these infections are intangible.

Introducción. Las infecciones asociadas a la atención en salud son un efecto adverso frecuente. Los neonatos son un grupo poblacional afectado debido a su inmadurez inmunitaria. La Organización Mundial de la Salud estima que estas infecciones varían entre 5% a 25% en función del nivel de ingresos de cada país. En Colombia se evidencia un subregistro para estas infecciones, particularmente en los neonatos. Este estudio buscó identificar los factores de riesgo, microorganismos más comunes, y las vías de transmisión y colonización relacionadas a las infecciones asociadas a la atención en salud en neonatos, según lo reportado en la literatura mundial. Metodología. Se realizó una búsqueda sistemática por duplicado, que incluyó pesquisa de artículos, primera lectura y exclusión de duplicados, conciliación entre autores y evaluación de la calidad, en la base de datos PubMed, con artículos publicados entre los años 2014 a 2019. Resultados. El nivel de evidencia y el grado de recomendación fue bueno en general (niveles 1 y 2, recomendación A y B). Los factores de riesgo más comunes fueron la prematuridad y el bajo peso al nacer, el uso de catéter venoso central, ventilación mecánica, estancia hospitalaria prolongada y el uso de antibióticos por largo tiempo. Se reportaron microorganismos de importancia como Staphylococcus coagulasa negativos y Serratia marcenscens, y vías de transmisión y colonización comunes como el torrente sanguíneo, la vía respiratoria, la gastrointestinal y la piel. Conclusión. Las infecciones asociadas a la atención en salud son más frecuentes de lo estimado y se pueden prevenir con la adopción de políticas sanitarias, como son un correcto lavado de manos, la desinfección del ambiente y equipos médicos, un adecuado cuidado de la piel del neonato y protocolos de aislamiento para pacientes con estas infecciones
Introduction. Health care-associated infections are a frequent adverse effect. Neonates are an affected population group due to their immune immaturity. The World Health Organization estimates that these infections vary between 5% to 25% depending on the income level of each country. In Colombia these infections are underreported, particularly in neonates. The aim of this review was to identify the risk factors, the most common microorganisms, and the routes of transmission for these type of infections in neonates, as reported in the world literature. Methodology. A systematic duplicate search was carried out in PubMed, with articles published between 2014 to 2019, which included a search for articles, reading and exclusion of duplicates, reconciliation between authors, and quality assessment. Results. The level of evidence and the grade of recommendation was optimal in general (levels 1 and 2, recommendation A and B). The most common risk factors were prematurity and low birth weight, the use of central venous catheter, mechanical ventilation, prolonged hospital stay, and long-term use of antibiotics. Microorganisms such as coagulase negative Staphylococcus and Serratia marcenscens were reported, and common routes of transmission such as the bloodstream, respiratory tract, gastrointestinal tract, and skin were described. Conclusion. Health care-associated infections are more frequent than estimated, and can be prevented with the adoption of health policies, such as proper hand washing, disinfection of environmental surfaces and medical equipment, an adequate skin care of the neonate, and isolation protocols for patients with these infections

BACKGROUND: Nosocomial infections are a leading cause of morbidity, costs, and mortality in preterm newborns. Most reports regarding nosocomial infections in neonatal intensive care units (NICU) are focused on bacterial infections and there is limited information regarding the impact of nosocomial viruses. The objective of this study was to assess the impact of nosocomial respiratory syncytial virus (RSV) infections in a NICU. METHODS: This was a retrospective cohort design from a NICU in a general hospital in Mexico. We included 24 newborn infants with nosocomial RSV infection and 24 infants without RSV matched by gestational age, birth weight, and the period of time of hospitalization. RESULTS: Infants with nosocomial RSV infection had longer hospitalization duration (median 24 days vs. 13 days; Pâ¯=â¯.05), increased antibiotic use (45.8% vs. 8.3%; Pâ¯=â¯.003), more mechanical ventilation requirement (54.2% vs. 0.4%; P <.001), more frequent nosocomial infections (45.8% vs. 0%; P <.001), and higher hospitalization direct costs (median 3,587.20 USD vs. 1,123.60 USD; Pâ¯=â¯.001) after nosocomial RSV detection. CONCLUSIONS: Nosocomial RSV infections are associated to a significant increase of costs in infants hospitalized in the NICU. Evaluation of interventions that may reduce the incidence of nosocomial RSV infections in this setting is warranted.

BACKGROUND: Urinary tract infections account for 8%-21% of health care-associated infections; of these, 80% are associated with the use of a urinary catheter. METHODS: A quasi-experimental study was conducted in 2 medical-surgical intensive care units (ICUs) with 48 beds and 3 step-down units (SDUs) with 95 beds in a private tertiary care hospital in Sao Paulo, Brazil. The study had 3 phases over a 9-year period to determine the sustainability of a program for continuous reduction of catheter-associated urinary tract infection (CAUTI). RESULTS: Over the 3 phases of the study, rates of CAUTI in the ICUs fell from 7.0 to 3.5 to 0.9 infections per 1,000 catheter days. In the SDUs, CAUTI rates decreased from 14.9 to 6.6 to 1.0 per 1,000 catheter days. Comparisons of CAUTI rates in the 3 study phases, both in the ICUs and SDUs, showed significant reductions both between the 3 periods and in all possible combinations of analysis phases (all P < .001). CONCLUSIONS: These results suggest that it is possible to reduce CAUTI rates to near zero and sustain these rates, but it requires a multidisciplinary team with different strategies that require continuous monitoring.
