Objective: To assess the knowledge of dietitians regarding fasting abbreviation and the preoperative fasting time practiced in hospitals in the state of Rio de Janeiro, Brazil. Methods: This is a cross-sectional, descriptive study involving clinical dietitians who work in hospitals in the state of Rio de Janeiro. Data were collected through the application of an online structured questionnaire and analyzed through descriptive statistics and the Chi-Square test to verify associations at a significance level of 5%. Results: Out of the 84 participating dietitians, 85% had heard about fasting abbreviation and supplements for this purpose, but 31.33% did not correctly describe current recommendations. In 48.81% of hospitals, the actual preoperative fasting time exceeds 12 hours, and 51.81% do not have a fasting abbreviation protocol. According to dietitians, fasting abbreviation is a practice that reduces surgical stress (91.57%), recommended for all types of surgeries, regardless of size (65.43%). The resistance of professionals to adopting new practices was identified as the main challenge to implementing the fasting abbreviation protocol (78.79%). There was no association between the overall knowledge level of professionals, the length of education, and specialization (p > 0.05). Conclusion: The high level of knowledge among dietitians about fasting abbreviation contrasts with the maintenance of traditional preoperative fasting techniques. The absence of institutional protocols and ineffective communication among teams strongly contribute to the non-incorporation of new practices into perioperative routines.
