ABSTRACT
Objective: analyse non-pharmacological measures of prevention of the Covid-19 adopted by health professionals in the Primary Attention to Health in family coexistence.Methods: transversal and analytical study performed with 229 health professionals of the Primary Attention. Data were collected through a virtual questionnaire in the platform SurveyMonkey. The data analysis was performed by the Chi-Square Test, exact of Fisher and logistic regression.Results: most of the professionals used hygiene measures of hands, environment cleaning, food hygiene, use of tissue masks and physical distancing of relatives. Male single/divorced health professionals have smaller chance to adopt environment cleaning, food hygiene and use of tissue masks.Conclusion: the adoption of non-pharmacological measures against Covid-19 by health professionals in family coexistence is essential for reducing contamination risk among their relatives.
ABSTRACT
OBJECTIVE: to analyze the scientific evidence available on the different reprocessing methods and the necessary conditions for reuse of the N95 face respirator mask or equivalent. METHOD: an integrative literature review. The PICO strategy was used to elaborate the question. The search was conducted in four databases: PubMed, SciVerse Scopus, WebofScience and EMBASE, considering any period of time. RESULTS: a total of 32 studies were included from the 561 studies identified, and they were presented in two categories: "Conditions for reuse" and "Reprocessing the masks". Of the evaluated research studies, seven(21.8%) addressed the reuse of the N95 face respirator mask or equivalent and 25(78.1%) evaluated different reprocessing methods, namely: ultraviolet germicidal irradiation(14);hydrogen peroxide(8);vapor methods(14);using dry heat(5) and chemical methods(sodium hypochlorite[6], ethanol[4] and sodium chloride with sodium bicarbonate and dimethyldioxirane[1]). We emphasize that different methods were used in one same article. CONCLUSION: no evidence was found to support safe reprocessing of face respirator masks. In addition, reuse is contraindicated due to the risk of self-contamination and inadequate sealing.
ABSTRACT
Objective:To culturally adapt the Face Mask Use Scale to Brazilian Portuguese and assess its psychometric properties. Methods: This is a methodological, cross-sectional, quantitative study, which comprised the following steps: translation;Portuguese version consensus;assessment by an expert committee;back-translation and comparison with the original version;pilot test;and psychometric assessment of the Face Mask Use Scale (FMUS). Results: The original version of FMUS was translated into Brazilian Portuguese. Content validity was performed by a panel of five experts.The Content Validity Index for the scale (CVI-S/Ave) was 0.87 and for the items (CVI-I) it ranged from 0.6 to 1.0. The FMUS - Brazilian Portuguese version (FMUS-BP) was applied to 4822 adults with a mean age of 30 years (SD = 11.7).For internal consistency, Cronbach's alpha was 0.86. The original two-factor model of the FMUS was not suitable for the Brazilian population due to the use of Exploratory Factor Analysis and Confirmatory Factor Analysis. Thus, an Exploratory Factor Analysis was carried out to investigate the factor structure of the FMUS-BP again and a new potential model of the FMUS-BP for better explanation. The FMUS-BP presented a factor structure different from the original model. Items were aligned on a single factor, creating a one-dimensional instrument that explained 59.7% of the total variance. Construct validity by known-groups was satisfactory (p <0.001). Conclusion: The FMUS-BP is reliable and valid to measure the practice of using masks among the Brazilian population, especially in the COVID-19 pandemic.
