Implementation of evidence-based medicine in dietetic practice: Current status and hurdles in Italy

Background: Health professionals, including dietitians, should adapt their clinical daily practice to evidence-based practice (EBP), but this does not happen often in daily practice. The aim of this study was to investigate the current status and barriers to evidence-based practice among dietitians. Methods: This was a mixed-method, cross-sectional, national study (questionnaire and focus group) performed on working and registered dietitians, both self-employed and employed by public hospitals. The main outcomes were EBP knowledge, frequency of use, and proficiency scores. Barriers to EBP implementation were also collected, as well as qualitative information from the focus group. Results: Forty-three dietitians were enrolled from August to November 2021 in Italy. Overall, EBP knowledge was moderate/good. Younger dietitians (< 50 years old) obtained better results than their older colleagues. A similar trend was observed in terms of seniority. There was a discrepancy between EBP knowledge and perception of EBP implementation: the worst scores were obtained by participants who claimed an already complete integration of EBP. The average frequency of EBP use was moderate, with higher scores in dietitians ≥ 50 years old and with seniority ≥ 20 years. EBP proficiency instead was poor. The focus group revealed a lack of time and resistance to change as the main barriers. Conclusion: The importance of EBP is well-acknowledged, but it is not correctly implemented yet, because of identified barriers that need to be fixed. These barriers include a lack of dedicated time, inadequate EBP training, and resistance to change, especially in hierarchical environments.
