ABSTRACT

A partir de la declaración de la Organización Mundial de la Salud del comienzo de la pandemia COVID-19 causada por el virus SARS-CoV-2 en marzo de 2020, los profesionales de la salud se vieron expuestos a esta enfermedad altamente contagiosa y potencialmente mortal que generó múltiples desafíos a toda la comunidad científica. Provocando cambios de paradigmas en la atención de los pacientes y en el uso de las barreras de protección personal. A nivel mundial se crearon múltiples protocolos para la atención odontológica a medida que se iba desarrollando e investigando el comportamiento del virus. Esta revisión bibliográfica resume las indicaciones y recomendaciones basadas en las evidencias disponibles para disminuir las posibilidades de contaminación ante la exposición a este virus, incluyendo medidas a utilizar desde el ingreso del paciente, los métodos de protección personal, la descontaminación y esterilización del material, así como también la desinfección del área de trabajo. Aunque se ha hecho un gran esfuerzo por mejorar los procesos de bioseguridad a nivel científico tecnológico, hay evidencias de que el factor humano sigue siendo el eslabón más débil de esta cadena.


Since the declaration by the World Health Organization of the beginning of the COVID-19 pandemic caused by the SARS-CoV-2 virus in March 2020, health professionals were exposed to this highly contagious and potentially fatal disease that generated multiple challenges to the entire scientific community. It caused paradigm shifts in patient care and in the use of personal protective barriers. Multiple protocols for dental care were created worldwide as the behavior of the virus was developed and investigated. This bibliographic review summarizes the indications and recommendations based on the available evidence to reduce the possibilities of contamination when exposed to this virus, including measures to be used from patient admission, personal protection methods, decontamination and sterilization of material, as well as disinfection of the work area. Although a great effort has been made to improve biosafety processes at the scientific and technological level, there is evidence that the human factor continues to be the weakest link in this chain.

ABSTRACT

OBJECTIVE@#To study the effectiveness and feasibility of cryogenic disinfectants in different cold scenarios and analyze the key points of on-site cryogenic disinfection.@*METHODS@#Qingdao and Suifenhe were selected as application sites for the manual or mechanical spraying of cryogenic disinfectants. The same amount of disinfectant (3,000 mg/L) was applied on cold chain food packaging, cold chain containers, transport vehicles, alpine environments, and article surfaces. The killing log value of the cryogenic disinfectant against the indicator microorganisms ( Staphylococcus aureus and Escherichia coli) was used to evaluate the on-site disinfection effect.@*RESULTS@#When using 3,000 mg/L with an action time of 10 min on the ground in alpine regions, the surface of frozen items, cold-chain containers, and cold chain food packaging in supermarkets, all external surfaces were successfully disinfected, with a pass rate of 100%. The disinfection pass rates for cold chain food packaging and cold chain transport vehicles of centralized supervised warehouses and food processing enterprises were 12.5% (15/120), 81.67% (49/60), and 93.33% (14/15), respectively; yet, the surfaces were not fully sprayed.@*CONCLUSION@#Cryogenic disinfectants are effective in disinfecting alpine environments and the outer packaging of frozen items. The application of cryogenic disinfectants should be regulated to ensure that they cover all surfaces of the disinfected object, thus ensuring effective cryogenic disinfection.

ABSTRACT

Experimental model of Pseudomonas aeruginosa biofilm was established in vitro by using biofilm reactor. The aim of this study was evaluating the removal effect of two kinds of water flowing through bactericide resin on Pseudomonas aeruginosa biofilm, and exploring the effectiveness of continuous treatment with low concentration disinfection factor on dental unit waterlines. The experimental group selected 1-2 mg/L iodinated resin (IR) filtered water and bromined hydantoin resin (BHR) filtered water with the control group selecting the sterile distilled water. Biofilms were treated by using the immersion method for 3, 7, 10, 20, and 40 days. Total viable count (TVC) and laser confocal microscopy method (CLSM) were selected to evaluate the biofilm removal effect. The result of TVC showed that in group IR, the bacterial clearance after the treatment of 3, 7, 10, and 20 days was lower than 99.9% and unqualified. The bacterial clearance after the treatment of 40 days was 99.9%,which is qualified. In group BHR, it was lower than 99.9% and unqualified after the treatment of 3, 7, and 10 days. It was and 99.99%, 100.00% after the treatment of 20, 40 days, respectively. The result of CLSM showed that before treatment, Pseudomonas aeruginosa biofilm showed a sheet and mass distribution. The bacterial coverage was 19.24%±1.97%. The proportion of viable bacteria was 93.91%±1.39%, and the biofilm matrix coverage was 17.69%±1.11%. After 20 days of treatment, the biofilm was decreased in the IR group, with the biofilm bacterial coverage reducing to 6.77%±1.61%, the proportion of live bacteria reducing to 54.85%±5.65%, and the biofilm matrix coverage reducing to 2.41%±0.85%.There was significant difference from the pre-treatment and the control (F=359.996,P<0.001). No biofilm-like structure was found in the BHR group. After 40 days of treatment, there was still a small amount of biofilm matrix residue in the IR group, with no bacterial coverage observed. The biofilm matrix coverage was 0.67%±0.47% (F=1 021.373,P<0.001). No biofilm-like structure was found in the BHR group. In conclusion, the continuous application of BHR filter water has more advantages in killing microorganisms in biofilms, removing live and dead bacteria and biofilm matrix in biofilms. Treatment water containing corresponding low concentration disinfection factors can play an important role in the field of biofilm control in dental unit waterlines.

ABSTRACT

Objetivo: Os ortodontistas usam alicates ortodônticos continuamente, e essas ferramentas têm um forte potencial para infecções nosocomiais. Este estudo teve como objetivo comparar a eficiência de três métodos de desinfecção de alicates ortodônticos. Material e Métodos: As pontas ativas de 26 alicates ortodônticos (cortadores distais e alicates Weingart) foram contaminadas com microrganismos, vírus e esporos S. aureus, E. coli e C. albicans. Os métodos de controle microbiano foram desinfecção com álcool 70%, esterilização com esferas de vidro (250 °C calor seco) e irradiação com luz ultravioleta (250 nm UV-C) por 30 e 60 segundos. O número de unidades formadoras de colônias (UFC) e unidades formadoras de placas (UFP) foi quantificado e comparado para cada microrganismo após incubação em placas de cultura. Resultados: Todas as pontas do alicate dos grupos que receberam luz ultravioleta ou foram submetidos à esterilização com esferas de vidro apresentaram número significativamente menor de esporos, bactérias e fungos do que suas respectivas amostras controle (p<0,001). A desinfecção física com luz UV-C pode representar uma alternativa confiável em comparação com outros métodos químicos e físicos devido ao aumento de microrganismos resistentes a produtos químicos e à emissão de subprodutos nocivos após o tratamento químico. Conclusão: Os métodos de controle microbiano testados foram eficazes na desinfecção de alicates ortodônticos, tornando a luz ultravioleta-C uma alternativa promissora para eliminar os microrganismos dos alicates (AU)


Objective: Orthodontists use orthodontic pliers continuously, and these tools have a strong potential for nosocomial infections. This study aimed to compare the efficiency of three methods for disinfecting orthodontic pliers. Material and Methods: The active tips of 26 orthodontic pliers (distal end cutters and Weingart pliers) were contaminated with S. aureus, E. coli, and C. albicans microorganisms, viruses, and spores. The microbial control methods were 70% alcohol disinfection, glass bead sterilization (250 °C dry heat), and ultraviolet light irradiation (250 nm UV-C) for 30 and 60 seconds. The number of colony-forming units (CFU) and plaque-forming units (PFU) was quantified and compared for each microorganism after incubation in culture plates. Results: All tips of the pliers in the groups that received ultraviolet light or were subjected to glass bead sterilization showed a significantly lower number of spores, bacteria, and fungi than their respective control samples (p<0.001). Physical disinfection with UV-C light may represent a reliable alternative compared to other chemical and physical methods due to the increase in microorganisms resistant to chemical products and the emission of harmful by-products after chemical treatment. Conclusion: The tested microbial control methods were effective in the disinfection of orthodontic pliers, making ultraviolet-C light a promising alternative to eliminate microorganisms from pliers (AU)

ABSTRACT

Abstract The purpose of this study was to compare the effect of different disinfection protocols of dentin on bond strength of an MDP-containing universal adhesive. Twelve extracted mandibular third molars were separated horizontally at the mid-coronal of crown to get smooth and sound dentin surfaces using low-speed diamond saw. The teeth were randomly fallen into four groups: chlorhexidine (CHX), ozone, Er,Cr:YSGG laser irradiation (LASER) and no treatment (control). After cavity disinfection application, a universal adhesive (G-Premio Bond) was applied to the surface of dentin according to self-etch mode as instructed by the manufacturer. After incremental built-up of composite resin (Charisma Smart), the specimens were immersed in distilled water at 37°C for 24h. Dentin/composite beams with 1 mm² cross sectional area were produced and micro-tensile bond strength (µTBS) was applied on these beams (n=20). Failure mods were determined under a stereomicroscope at ×40. The resin penetration of samples stained with Rhodamine B fluorochrome dye was examined with a confocal laser scanning microscope. Statistical analysis was performed with SPSS-22. Test results were analyzed using One-way Anova and Tukey HSD Post-Hoc tests (p0.5). All applications of cavity disinfection procedures decreased the µTBS of the resin-dentin interface.


Resumen El propósito de este estudio fue comparar el efecto de diferentes protocolos de desinfección de la dentina sobre la fuerza de unión de un adhesivo universal que contiene MDP. Doce terceros molares mandibulares extraídos se quebraron horizontalmente en la mitad de la corona para obtener superficies de dentina lisas y sólidas utilizando una sierra de diamante de baja velocidad. Los dientes se dividieron aleatoriamente en cuatro grupos: clorhexidina (CHX), ozono, irradiación con láser Er,Cr:YSGG (LASER) y ningún tratamiento (control). Después de la aplicación de la desinfección de la cavidad, se aplicó un adhesivo universal (G-Premio Bond) a la superficie de la dentina según el modo de autograbado indicado por el fabricante. Después de la obturación con resina compuesta (Charisma Smart), las muestras se sumergieron en agua destilada a 37°C durante 24h. Se produjeron porciones de dentina/resina con un área de sección transversal de 1 mm² y se aplicó una fuerza de adhesión microtensile (µTBS) (n=20). Los modos de falla se determinaron bajo un microscopio estereoscópico a ×40. La penetración de la resina de las muestras teñidas con colorante fluorocromo rodamina B se examinó con un microscopio de barrido láser confocal. El análisis estadístico se realizó con SPSS-22. Los resultados de las pruebas se analizaron utilizando las pruebas post-hoc Anova unidireccional y Tukey HSD (p0.5). Todas las aplicaciones de procedimientos de desinfección de cavidades redujeron el µTBS de la interfaz resina-dentina.

ABSTRACT

Introduction: Chlorine, ethyl alcohol, and quaternary ammonium are disinfectants with antiviral activity against SARS-Cov2. However, there are no previous reports of their use and handling for cleaning and disinfection in dental offices. Objetive: To determine the use and management of disinfectants in critical and non-critical areas used by dentists in San Luis Potosí, Mexico, during the COVID-19 pandemic. Material and Methods: A validated cross-sectional survey was applied online to 100 dentists in San Luis Potosí between February and June 2021. Participants were informed about the handling of personal data according to the standard DOF regulations (DOF 07-05-2010). Results: A total of 100 dentists were included in the study, 63% female and 37% male, with a mean age of 26 years. The most widely used disinfectants during the pandemic in critical areas were Lysol® and 0.1% sodium hypochlorite in non-critical areas. Eighty-five percent of dentists know the adverse effects of inappropriate use of disinfectants, 72% did not have any sign or symptom associated with the use of disinfectants. The most used protection barrier was gloves (97%). Sixty-seven per cent of dentists disposed of disinfectant waste down the drain. Conclusion: Sodium hypochlorite and quaternary ammonium compounds and/or ethanol are used to clean non-critical and critical areas in dental offices. However, appropriate measures for their management are not adopted. It is necessary to implement educational strategies to improve the use and management of disinfectants in dental practice.


Introducción: Cloro, alcohol etílico y amonio cuaternario son desinfectantes que muestran actividad antiviral contra el SARS-Cov2, sin embargo, no existen reportes previos de su uso y manejo para la limpieza y desinfección en clínicas dentales. Objetivo: Determinar el uso y manejo de los desinfectantes en áreas críticas y no críticas empleados por los odontólogos en San Luis Potosí durante la COVID-19. Material y Métodos: Encuesta transversal validada y aplicada on-line a 100 odontólogos de San Luis Potosí durante febrero-junio 2021. Se informó a los participantes sobre el manejo de datos personales de acuerdo a la norma (DOF 05-07-2010). Resultados: Se incluyeron un total de 100 odontólogos, 63% del sexo femenino y 37% del sexo masculino, con una edad promedio de 26 años. Los desinfectantes más utilizados durante la pandemia en las áreas críticas fueron el Lysol® y el hipoclorito de sodio al 0.1% en áreas no críticas. El 85% de los odontólogos conocen los efectos adversos del uso inadecuado de los desinfectantes, 72% no tuvieron algún signo o síntoma asociado al uso de desinfectantes. La barrera de protección más utilizada fueron los guantes (97%). El 67% de los odontólogos eliminó los desechos de desinfectantes por la coladera. Conclusión: Para la limpieza de las áreas no críticas y críticas en las clínicas dentales se utilizan el hipoclorito de Sodio y compuestos de amonio cuaternario y/o etanol, sin embargo, no se utilizan las medidas adecuadas para su manejo. Es necesario implementar estrategias educativas para mejorar el uso y manejo de desinfectantes en la práctica dental.

ABSTRACT

Background: Beef slaughterhouses must use a carcass decontamination procedure to control pathogens and thus prevent foodborne diseases transmitted by meat. Objectives: This study aimed to characterize beef carcass decontamination procedures at slaughterhouses located in the province of Antioquia (Colombia). All the slaughterhouses were in service, registered, and approved by Invima (Instituto Nacional de Vigilancia de Medicamentos y Alimentos in Spanish) at the time of the study. Methods: This descriptive study collected information from 23 beef slaughterhouses between July 2019 and April 2021 through documentary reviews and visits to slaughterhouses, using forms and questionnaires. Results: The study allowed the characterization of the procedures used to decontaminate beef carcasses, showing that the chemical disinfection of the carcasses is used to control microorganisms in at least 73.9% of the slaughterhouses analyzed. According to secondary sources, it was found that most of the slaughterhouses are small (slaughter volume <50,000 heads per year); 10 of them use citric acid, lactic acid, peracetic acid, and a mixture of organic acids in concentrations between 900 and 1,200 ppm, 1.5 and 1.7%, 180 and 190 ppm, and 900 and 1,200 ppm, respectively, as carcass disinfectants and according to the technical data sheet of the product. During the visits and through the application of the questionnaire, it was found that the 12 slaughterhouses had implemented chemical disinfection which is not scientifically based, using manual devices as an intervention method to control pathogenic microorganisms. It was found that the type of company, slaughter volume, and the lack of financial resources are the determining factors in the selection of decontamination procedures. The validation of the beef carcass decontamination procedures in the different slaughterhouses in the study was demonstrated. Conclusions:Although it was established that at least one decontamination procedure, such as chemical disinfection, is used in the slaughterhouses of study, this option is not supported by scientific or technical evidence. The findings support the need for improvements in the slaughterhouses of the province of Antioquia, including the improvement of surveillance programs to reduce pathogens in the meat chain effectively.


Antecedentes: Las plantas de beneficio animal deben utilizar un procedimiento de descontaminación de canales para el control de patógenos y con ello, prevenir la aparición de enfermedades transmitidas por el consumo de carne. Objetivos: El objetivo de este estudio fue caracterizar el procedimiento de descontaminación de canales bovinas en las plantas de beneficio animal del Departamento de Antioquia, Colombia, que se encontraban en servicio, inscritas y autorizadas por el Invima al momento del estudio. Métodos: Este estudio descriptivo recolectó información de 23 plantas de beneficio animal de la especie bovina, a partir de revisiones documentales y visitas a las plantas, usando formatos y cuestionarios entre julio de 2019 y abril de 2021. Resultados: El estudio permitió caracterizar los procedimientos y técnicas de descontaminación de canales bovinas, revelando que en al menos el 73,9% de las plantas de beneficio estudiadas se realiza la desinfección química de las canales para el control de microorganismos. A partir de fuentes secundarias, se encontró que la mayoría de las plantas de beneficio animal en el Departamento de Antioquia son muy pequeñas, 10 de ellas utilizan productos de desinfección de canales, tales como el ácido cítrico, ácido láctico, ácido peracético y mezcla de ácidos orgánicos en concentraciones entre 900 y 1200 ppm, 1,5 y 1,7%, 180 y 190 ppm y 900 y 1200 ppm, respectivamente; y estos son utilizados de acuerdo con las recomendaciones de la respectiva ficha técnica del producto. Por otro lado, durante la visita a las plantas de beneficio y mediante la aplicación del cuestionario, se constató que las 12 plantas visitadas han implementado la desinfección química como método de intervención para el control de microorganismos patógenos, realizando su aplicación mediante dispositivos manuales, no obstante, estas prácticas no están fundamentadas científicamente. Por otro lado, se estableció que aparentemente el tipo de empresa, volumen de sacrificio y falta de recursos financieros son los factores que determinan la elección del procedimiento de descontaminación de canales. De igual manera, se evidenció la necesidad de realizar estudios para validar la efectividad del procedimiento de descontaminación en las diferentes plantas de beneficio. Conclusiones: Aunque se estableció que en las plantas de beneficio animal visitadas se implementa al menos una técnica de intervención como la desinfección química, esta elección no tiene un sustento con base a fundamentos científicos y técnicos. Estos hallazgos respaldan la necesidad de mejoras en las plantas de beneficio animal del Departamento, incluyendo mejoras al programa de vigilancia de la reducción efectiva de patógenos en la cadena cárnica.

ABSTRACT

Introducción: Se está viviendo en un contexto de pandemia por COVID-19, en donde se evidencia la escasez de equipos de protección personal en salud y se prevé que continuará en el corto y mediano plazo. Por lo que considerar la reutilización o el uso prolongado de algunos equipos de protección personal, en especial de los respiradores, podría ser una alternativa a considerar. Objetivo: Revisar y dar a conocer, en base a evidencia científica, distintas formas de desinfección para poder reutilizar de manera segura y asequible los respiradores N95. Comentarios principales: Los respiradores N95 o sus equivalentes son de uso exclusivo del personal de salud para la atención de pacientes con sospecha o confirmación de COVID-19 y en procedimientos con generación de aerosoles. Su eficacia depende en gran medida del estado del respirador, de la capacidad de filtración, del sellado y de su uso adecuado. Son diversos los métodos para desinfectar, como la luz ultravioleta tipo C, el peróxido de hidrógeno, calor seco y húmedo, ozono, irradiación por microondas, etc. Si estos procedimientos no son realizados adecuadamente, podrían no ser efectivos. Comentarios globales: En escenarios de escasez de equipos de protección personal la reutilización es un procedimiento viable, económico, seguro, potencialmente escalable y fácil de realizar. Los respiradores N95 requieren un procedimiento especial de desinfección para preservar su capacidad de filtración y sellado. Existe un limitado número de ciclos de desinfección y reutilización. La estufa en calor seco podría ser el método más asequible en entornos privados(AU)


Introduction: We are living in a context of COVID-19 pandemic, where the shortage of personal protective equipment in health is evident and it is expected that it will continue in the short and medium term. So, considering the reuse or prolonged use of some personal protective equipment, especially respirators, could be an alternative to consider. Objective: To review and disseminate, based on scientific evidence, different forms of disinfection in order to safely and affordably reuse N95 respirators. Main comments: N95 respirators or their equivalents are for the exclusive use of health personnel for the care of patients with suspected or confirmed COVID-19 and in aerosol generation procedures. Its effectiveness depends to a large extent on the condition of the respirator, the filtration capacity, the sealing and its proper use. There are several methods to disinfect, such as ultraviolet light type C, hydrogen peroxide, dry and humid heat, ozone, microwave irradiation, etc. If these procedures are not performed properly, they may not be effective. Global feedback: In personal protective equipment shortage scenarios, reuse is a viable, economical, safe, potentially scalable and easy-to-perform procedure. N95 respirators require a special disinfection procedure to preserve their filtration and sealing capacity. There are a limited number of disinfection and reuse cycles. Dry heat stove might be the most affordable method in private settings(AU)

ABSTRACT

This study aimed to evaluate if 2.5% sodium hypochlorite compromises the adhesion of bonding materials. The factors in the study were the irrigation solutions in two levels: 2.5% sodium hypochlorite and saline solution; and the adhesive systems used in three levels: three-step adhesive, universal adhesive, and two-step self-etch adhesive systems. The answer variable used was the microshear bond strength obtained through a universal testing machine and fracture mode. Six groups were obtained (n=10) : Etch-and-rinse/Saline (saline solution + 3-step adhesive system - Scotchbond Multipurpose, 3M ESPE); Universal/saline (saline solution + universal adhesive system ­ Prime&Bond,); Self-etch/saline (saline solution + 2-step self-etch adhesive systems - Clearfil SE Bond); Etch-and-rinse/Hypo (sodium hypochlorite 2,5% + 3-step adhesive system - Scotchbond Multiuso); Universal/Hypo (sodium hypochlorite 2,5% + universal adhesive system ­ Prime&Bond); Self-etch/Hypo (sodium hypochlorite 2,5% + 2-step self-etch adhesive system - Clearfil Se Bond). The specimens were obtained from 60 healthy bovine incisors. The crowns were separated from the roots, and the regularization of the buccal surface was performed. The groups received saline solution and 2.5% sodium hypochlorite for 30 minutes, respectively. A matrix of 1mm and 3mm oh height was stabilized by Scotch tape to obtain the resin sticks. Afterward, the bond strength test was performed in a universal testing machine at 1mm/min speed. The data were analyzed with normality Shapiro-Wilk, two-way ANOVA, and Tukey's tests (p<0.001). Etch-and-rinse and Self-etch adhesives presented the highest bond strength values after irrigation with saline solution and 2.5% sodium hypochlorite, respectively (P < 0.01). The irrigation with 2.5% sodium hypochlorite decreased the bond strength values of Etch-and-rinse and Universal (P < 0.01). On the other hand, 2.5% sodium hypochlorite improved the bond strength values of Self-etch (P < 0.01). In conclusion, 2.5% sodium hypochlorite negatively impacted the bond strength of Etch-and-rinse and Universal but improved the adhesion of Self-etch.

ABSTRACT

This study proposes a methodology to disinfect anesthetic cartridges used in the dental clinics of the Federal University of Amazonas. The research used 50 glass and 50 plastic cartridges. The anesthetic cartridges were disinfected through two different methods: immersion and friction. The experiments were carried out in two distinct sets: microbio-logical test and experimental validation, using 70% Alcohol, Polyvinylpyrrolidone, 2% Chlorhexidine, and 0.5% Chlorhexidine with Alcohol. The analysis of the results was based on mean and standard deviation statistical estimators obtained by the MATLAB software. Experiments conducted on plastic cartridges employing immersion in disinfec-tants elucidated that 2% Chlorhexidine and 0.5% Chlorhexidine produced better results than 70% Alcohol and Polyvinylpyrrolidone. For the experiments with glass material, 70% Alcohol and 2% Chlorhexidine presented the best results. In the experiments with different types of friction disinfections on the plastic material, the disinfectants 70% Alcohol and Polyvinylpyrrolidone presented similar performances. The disinfectants 2% Chlorhexidine and 0.5% Chlorhexidine obtained the best results compared to disinfec-tants 70% Alcohol and Polyvinylpyrrolidone. The analysis of experiments carried out with friction disinfection on glass found that the disinfectants 2% Chlorhexidine and 0.5% Chlorhexidine were similar. Moreover, the 2% Chlorhexidine and 0.5% Chlorhexidine disinfectants outperformed 70% Alcohol and 2% Chlorhexidine. Considering the efficacy of disinfection by disinfectant solutions evaluated in this study, the friction method with 2% Chlorhexidine proved to be more effective with the different disinfection methods.

ABSTRACT

Este estudo teve o objetivo de indicar estratégias de melhoria contínua dos processos de higienização de superfícies hospitalares de uma unidade de terapia intensiva através de abordagem Lean Healthcare. É um estudo de caráter exploratório, descritivo, observacional, em que a coleta de dados ocorreu no período de julho de 2021 a janeiro de 2022 por observações in loco e entrevistas com cinco profissionais do serviço de higienização. Utilizaram-se as ferramentas: Gemba, mapeamento de fluxo de valor e diagrama do espaguete adaptado, árvore da realidade atual (ARA), Matriz GUT, Matriz de esforço impacto e 5W2H, para levantar, analisar problemas e propor intervenções para futuras melhorias. Como indicador de qualidade do processo optou-se pelo uso de marcadores fluorescentes com análise de 10 higienizações terminais. Para tratamento dos dados utilizou-se o software Miro®, o Excel® e uma planta física projetada da área. Atendeu parcialmente às diretrizes SQUIRE 2.0 através do uso de ferramentas Lean com foco na melhoria da qualidade, segurança e cuidados em saúde. Identificou-se o uso inadequado de desinfetante e de equipamento de proteção individual, manejo incorreto de perfurocortante, além da ordem, técnica e movimentos incorretos. O percentual do indicador completo/correto do processo de higienização terminal foi de 70%. Além disso, o teste do marcador fluorescente demonstrou apenas 33% de conformidade da limpeza, concluindo que não houve padrão em nenhuma higienização terminal observada. Além disso, identificou-se inadequações que comprometeram a qualidade do processo de limpeza e desinfecção de leitos, o que é uma premissa básica para otimização do trabalho e sustentabilidade institucional. Nesse contexto, os resultados sumarizados neste estudo demonstraram que a utilização das ferramentas Lean contribuiu para a proposição de intervenções objetivas baseadas nos reais problemas identificados e analisados.
