ABSTRACT BACKGROUND: The speed of the spread of coronavirus disease 2019 (COVID-19) has put enormous pressure on hospitals and other healthcare facilities. This, together with blockages in several countries, has hindered the availability and accessibility of the necessary personal protective equipment (PPE). OBJECTIVE: To identify, systematically evaluate and summarize the available scientific evidence on the efficacy, safety, safe use and reuse of PPE for healthcare professionals, for preventing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. DESIGN AND SETTING: Systematic review of studies analyzing products for disinfecting and enabling reuse of PPE for coronavirus within the evidence-based health program of a federal university in São Paulo (SP), Brazil. METHODS: A systematic search of the relevant literature was conducted in the PubMed, EMBASE, Cochrane Library, CINAHL, SCOPUS, Web of Science and LILACS databases, for articles published up to November 30, 2020. RESULTS: Ten studies were selected. These analyzed the use of N95, surgical and cotton masks, face shields, flexible enclosures with plastic covers or polycarbonate intubation boxes and plastic curtains; and also PPE disinfection using several substances. CONCLUSION: Combined use of a face shield with a N95 mask proved to be superior to other associations for protecting healthcare workers. Some products are useful for disinfecting PPE, such as 70% ethanol, 0.1% sodium hypochlorite and a mixture of quaternary ammonium and H2O2, and hydrogen peroxide. Ultraviolet light and dry heat at 70 °C can be used to decontaminate N95 masks. REGISTRATION NUMBER: DOI: 10.17605/OSF.IO/4V5FD at the OPENSCIENCE Framework.

OBJETIVO: pesquisar, entre um grupo de fonoaudiólogos, o grau de conhecimento e utilização das normas de biossegurança na rotina clínica. MÉTODO: foi realizada pesquisa por meio de um questionário respondido por cem profissionais de diferentes áreas de atuação (Audiologia Clínica, Audiologia Ocupacional, Voz, Neonatologia, Linguagem, Motricidade Orofacial e que atuam em mais de uma área). Cada item, respondido de forma positiva, correspondia a 1 ou 2 pontos, sendo a máxima pontuação (100%) correspondendo a 80 pontos. As respostas obtidas foram analisadas e as pontuações encontradas, padronizadas, ou seja, transformadas em índices percentuais indicando seu desempenho. O valor da percentagem de cada questionário poderia variar de 0 a 100%, sendo que quanto maior a percentagem obtida, maior o conhecimento e aplicabilidade das normas de biossegurança pelo profissional na rotina clínica. Foram adotadas as faixas de (0-25%), (26-50%), (51-75%) e (76-100%) para distinguir o nível de conhecimento e aplicação das medidas de precaução pelos participantes. RESULTADOS: dos cem fonoaudiólogos avaliados por meio dos questionários (100%), 1% obteve a percentagem na faixa de (0 a 25%), 45% em (26 a 50%), 50% entre (51 a 75%) e 4% (76 a 100%). CONCLUSÃO: a maioria dos profissionais que participaram conhece e aplica as medidas de biossegurança.

PURPOSE: research, among a group of speech pathologists, the degree of knowledge and use of standards of biosafety in clinical routine. METHOD: a survey was conducted through a questionnaire answered by one hundred professionals from different areas (Clinical Audiology, Occupational Audiology, Voice, Neonatology, Language, Orofacial Motricity and more than one performing area). Each item, responded in a positive way, corresponding to 1 or 2 points and the maximum score (100%) corresponding to 80 points. The responses were analyzed and the found scores were standardized, or converted into percentage index indicating its performance. The percentage value of each questionnaire could vary from 0 to 100%, and the greater the percentage obtained, the more knowledge and applicability of standards of biosafety professionals in the clinical routine. Tracks were taken (0-25%), (26-50%), (51-75%) and (76-100%) to distinguish the level of knowledge and application of precautionary measures by the participants. RESULTS: of one hundred speech therapists assessed by the questionnaires (100%), 1% obtained the percentage in the range (0 to 25%), 45% (26 to 50%), between 50% (51 to 75%) and 4% (76 to 100%). CONCLUSION: the most of the professionals who participated knows and applies biosafety measures.
