“…Sources of environmental contaminants include the skin, hair, and hands of healthcare professionals or the physical environment, such as operating tables, auxiliary tables, and anesthesia machines. 20 In this study, we observed the growth of the main microorganisms of epidemiological importance at different incubation times and sample collection sites. These results were consistent with the findings of previous studies on the contamination of the inspiratory and expiratory branches 21 that may be associated with processing that proves ineffective in disinfection.…”

The transmission of microorganisms in healthcare settings, including perioperative areas, has become a potential concern in recent studies. The occupancy of spaces by previously colonized or infected patients increases the risk of acquiring multidrug-resistant microorganisms, emphasizing the critical importance of robust cleaning and disinfection procedures. [1][2] The persistence of contamination on environmental surfaces has been linked to insufficient cleaning practices in operating rooms and anesthesia workspaces. This is of particular concern as eliminating multidrug-resistant microorganisms from these surfaces is a key strategy to mitigate the prevalence of healthcare-associated infections (HAIs) that significantly contribute to morbidity, mortality, and extended hospital stays. [2][3][4][5] The existing [3][4][5][6] cleaning practices in operating rooms and anesthesia work areas are inadequate; therefore, environmental surfaces remain contaminated. Removing multidrug-resistant microorganisms from operating room surfaces is essential to minimizing the risk of HAIs.Furthermore, HAIs contribute to major public health problems by increasing morbidity and mortality rates and prolonging the hospitalization time of patients. [1][2][3][4][5] In particular, surgical patients with open wounds are at a higher risk; 6 therefore, the potential for cross-transmission in the intraoperative environment poses a threat to patient safety. 7Contamination in the anesthesia work area, including the anesthesia cart, faucets, laryngeal masks, laryngoscope blades, touchscreens, keyboards, and the hands of professionals, can result in the transmission of infections that promote health risks, highlighting pneumonia associated with mechanical ventilation (PAVM). [1][2][3][4]8 Ventilator-associated pneumonia (VAP) is characterized as an infectious disease with an imprecise diagnosis and multiple causes, which allows divergent recommendations related to preventive measures, diagnosis, and treatment. [9][10][11] Because 24 h of intubation in invasive mechanical ventilation (IMV) favor the colonization of microorganisms in the lower airways, orotracheal

“…De igual manera la contaminación en las áreas de quirófano es una de las áreas más representativa en el estudio, en las que se indican reportes en colonización de estafilococos, especialmente en vías respiratorias (23). Otros estudios muestran que este patógeno persiste incluso luego de una limpieza y desafección de quirófano con muestras positivas tomadas durante el periodo peri operatorio (24). Además, Sánchez, A., Rincón., et al, en el área de pediatría y otras investigaciones previas.…”

Introducción: La resistencia bacteriana hacia antibióticos y desinfectantes es un severo problema sanitario mediado por mecanismos de resistencia, afecta a los sistemas de salud mundial debido a las pocas alternativas de tratamiento y elevados costos. Por otro lado, la sensibilidad a desinfectantes se ha visto disminuida al evaluar su efectividad in vitro según concentraciones recomendadas por entidades sanitarias como la OMS y MSP. Objetivo: Valorar la efectividad in vitro de desinfectantes de uso hospitalario en bacterias aisladas en las áreas de neonatología y quirófano del Hospital Humanitario Fundación Pablo Jaramillo Crespo – Cuenca – Ecuador. Metodología: Se realizó un estudio de campo, de tipo descriptivo de corte transversal. Se obtuvo muestras de las áreas de neonatología y quirófano del hospital Humanitario Fundación Pablo Jaramillo Crespo. Cuenca – Ecuador. Identificación bacteriológica mediante métodos fenotípicos para su posterior evaluación de susceptibilidad y resistencia por medio del método de Kirby – Bauer. Resultados: En el 48% de muestras hubo crecimiento microbiano identificando cepas de S. aureus, Enterococcus spp, Staphylococcus saprophyticus, Streptococcus agalactiae, Pseudomona spp, E. coli, Klebsiella spp. Destacando resistencia hacia β-lactámicos, cefalosporinas. Pseudomona resistente a meropenen y Enterococcus resistente hacia linezolid. La sensibilidad hacia desinfectantes es muy escasa con resistencia total a etanol, hipoclorito, Monopersulfato de potasio, glutaraldehído, sensibilidad de media a elevada con yodopovidona, amonio cuaternario, peróxido de hidrógeno a concentraciones aprobadas por autoridades sanitarias. Conclusión: Se valoró la efectividad in vitro de antibióticos y desinfectantes de uso hospitalario en bacterias aisladas de las áreas: neonatología y quirófano, encontrando un alto porcentaje de muestras resistentes. Área de estudio general: Microbiología. Área de estudio específico: Bacteriología. Tipo de estudio: Articulo original

“…Some have found that cleaning does not accurately predict disinfection, as determined by surface microbial colony counts, even if antimicrobial products are used. 3,29,30 We did not specifically measure disinfection, but over the 10-year period of improving environmental cleaning, we experienced a 75% reduction in overall hospitalacquired infection (HAI) rates, 55% reductions in class I and II surgical site infection (SSI) rates, and a 70% reduction in hospital-onset C. difficile rates. Other studies have also shown a reduction in HAIs with enhanced cleaning and associated disinfection.…”

Objective: Short-term improvements in hospital room cleaning can readily be achieved but are difficult to maintain. This is particularly true for high-risk, “high-touch” surfaces. Therefore, we embarked on a process to sustain improvements in surface cleaning and disinfection to reduce hospital-acquired infection (HAI) rates. Interventions: Our environmental services (EVS) and infection prevention departments incorporated a formal education, monitoring, and feedback process for focused cleaning and disinfection of high-touch surfaces into their routine policies and procedures in 2011. Cleaning validation was performed by infection prevention liaison nurses using a fluorescent targeting method to evaluate the thoroughness of cleaning. Results: Surface cleaning performance on medical-surgical units in 2011 was 74.7%, but this rate incrementally increased in response to the interventions and has been sustained at >90% for the past 6 years. Similar patterns of improvement were observed in the operating room, labor and delivery, endoscopy suite and cardiac catheterization laboratory. Conversely, HAI rates, particularly C. difficile rates, decreased by 75% and surgical site infection rates decreased by 55%. Conclusions: EVS training, monitoring, and feedback interventions, instituted 10 years ago have enhanced our environmental cleaning and disinfection efforts in multiple areas of the hospital and have been sustained to the present. Although other concurrent initiatives to reduce infection rates also existed, the improvements in environmental cleaning were associated with dramatic reductions in HAI rates over the 10-year period.
