This study aimed to assess the knowledge and behavior of professionals working in Intensive Care Units (ICU) related to the adoption of contact precautions for the control of hospital infections (HI). This cross-sectional study used a semi-structured questionnaire to collect data. Descriptive and multivariate analyses were carried out, including logistic regression and decision tree using CHAID algorithm. A total of 102 professionals participated in the study, of whom 36.3% presented appropriate knowledge and 51% appropriate behavior in relation to HI control measures. Nursing professionals had almost four times more chance (OR = 3.58, CI 1.48-8.68) of presenting appropriate behavior than the remaining professionals. The multivariate analysis did not reveal variables associated with knowledge. No statistically significant association was found between knowledge and behavior (p = 0.196). These results suggest the need to implement educational activities so as to permit a balance between theory and professionals' practice concerning HI preventive measures, aiming to improve knowledge and behavior.
