Abstract
OBJECTIVES: to assess the socio-cognitive factors determining adherence to standard precautions by nursing professionals in care practice during the COVID-19 pandemic in Brazil. METHODS: an analytical cross-sectional study, carried out with 9,039 nursing professionals in Brazil, using an electronic form containing participant sociodemographic, training and work variables, and the Brazilian version of the Standard Precautions Questionnaire. Descriptive and inferential statistics were used using the statistical software R. RESULTS: participants recognize standard precautions as effective measures to reduce infections and report intention to perform them. Training regarding standard precautions was evidenced as a facilitator of adherence (4.72; SD: 0.73), and problems related to materials (3.78; SD: 1.45) were a hindrance. CONCLUSIONS: among the determining factors, facilitating organization presented the highest score, followed by intention to perform. Facilitating and hindering factor identification makes it possible to develop intervention strategies to strengthen patient safety and reduce occupational risks among professionals.
