Scale of Adherence to Good Hospital Practices for COVID-19: Psychometric Properties.

To avoid hospital transmission, all COVID-19 prevention measures should be followed. This study aimed to evaluate the psychometric properties of a novel scale developed to assess adherence to good practices for COVID-19 in the hospital setting. A methodological cross-sectional study was conducted at a public hospital in the state of São Paulo, Brazil, with 307 healthcare providers. Data were collected using a questionnaire addressing sociodemographic/occupational data and the Adherence to Standard Precautions for COVID-19 scale. Cronbach's alpha coefficients and the intraclass correlation coefficients were used to measure internal consistency and temporal stability (test-retest analysis), respectively. Concurrent validity was evaluated using Spearman's correlation coefficients between the scores of the overall scale and its domains. Factorial structure was evaluated using exploratory factor analysis and goodness-of-fit of the model was tested using confirmatory factor analysis. Cronbach's alpha coefficients for the scale and its domains were higher than 0.7, except the psychosocial domain (0.61). All intraclass correlation coefficients were higher than 0.7. Strong correlations were found between the total score and the personal (0.84) and organizational (0.90) domains of the scale and a good correlation was found with the psychosocial domain (0.66). The fit of the multidimensional model was satisfactory for all parameters and the three-dimensional structure of the scale was confirmed by the fit of the factor loadings. The novel scale is a valid and reliable instrument for assessing adherence to good hospital practices for COVID-19.

Decontamination of stainless-steel bowls with 80% (w/v) alcohol for 30 s and 60 s: randomized experimental study.

OBJECTIVE: to compare the efficacy of 80% (w/v) alcohol, rubbed for 30 and 60 seconds, in the manual processing of stainless-steel wash bowls, after cleaning with running water and neutral detergent. METHOD: experimental study conducted in a hospital in the state of São Paulo, Brazil, on 50 bowls randomly divided into two groups of 25 bowls each for interventions of 30 and 60 seconds of rubbing with 80% (w/v) alcohol. RESULTS: based on the microbiological analyses collected, before and after the interventions for both groups, partial efficacy of the disinfectant was observed even when extending rubbing time. In both groups, there was a higher prevalence of survival of Pseudomonas aeruginosa, with 14 strains that were resistant to carbapenems, being, specifically, 11 to imipenem and three to meropenem. CONCLUSION: stainless-steel bed wash bowls decontaminated for reuse by 80% (w/v) alcohol, after cleaning with running water and neutral detergent, showed to be reservoirs of hospital pathogens. The use of bed wash bowls for patients with intact skin would not have worrying consequences, but considering those with non-intact skin and the contamination of professionals' hands, the results in this study justify the search for other decontamination methods or the adoption of disposable bed baths.

Objetivo: comparar a eficácia do álcool 80% (p/v), friccionado por 30 e 60 segundos, no processamento manual de bacias de banho em aço inoxidável, após limpeza com água corrente e detergente neutro. Método: estudo experimental realizado em hospital do estado de São Paulo, Brasil, com 50 bacias randomicamente distribuídas em dois grupos de 25, para as intervenções de 30 e 60 segundos de fricção com álcool 80% (p/v). Resultados: das análises microbiológicas coletadas, antes e após as intervenções para os dois grupos, verificou-se eficácia parcial do desinfetante, mesmo ampliando o tempo de fricção. Em ambos os grupos, observou-se maior prevalência de sobrevida de Pseudomonas aeruginosa, 14 cepas resistentes a carbapenens, especificamente, 11 ao imipenen e três ao meropenen. Conclusão: bacias de banho no leito em aço inoxidável, descontaminadas para reuso com álcool 80% (p/v), após limpeza com água corrente e detergente neutro, apresentam-se como reservatórios de patógenos hospitalares. O uso das bacias de banho no leito para pacientes com pele íntegra não teria consequências preocupantes, mas para aqueles com pele não íntegra e pensando na contaminação das mãos dos profissionais, os resultados dessa pesquisa justificam a busca de outros métodos de descontaminação ou a adoção de banho de leito descartável.

Objetivo: comparar la eficacia del alcohol al 80% (p/v), frotado durante 30 y 60 segundos, en el proceso de descontaminación manual de palanganas de baño de acero inoxidable, después de lavarlas con agua corriente y detergente neutro. Método: estudio experimental realizado en un hospital del estado de São Paulo, Brasil, con 50 palanganas divididas aleatoriamente en dos grupos de 25, para intervenciones de 30 y 60 segundos de frotamiento con alcohol al 80% (p/v). Resultados: los análisis microbiológicos recolectados, antes y después de las intervenciones para ambos grupos, demostraron efectividad parcial del desinfectante, incluso cuando se extendió el tiempo de fricción. En ambos grupos, se observó una mayor prevalencia de supervivencia de Pseudomonas aeruginosa, 14 cepas resistentes a carbapenemas, específicamente 11 a imipenem y tres a meropenem. Conclusión: las palanganas de baño de cama de acero inoxidable, descontaminadas para su reutilización con alcohol al 80% (p/v), después del lavado con agua corriente y detergente neutro, actúan como reservorios de patógenos hospitalarios. El uso de las palanganas de baño de cama no tendría consecuencias preocupantes para pacientes con la piel íntegra, pero para aquellos cuya piel no conserva su integridad y pensando en la contaminación de las manos de los profesionales, los resultados de esta investigación justifican la búsqueda de otros métodos de descontaminación o la adopción del baño de cama desechable.
