Variation in nutritional therapy practices: results of a survey on nutritional management of severe inflammatory bowel disease.

Objectives: The optimal nutritional management during a severe flare of inflammatory bowel disease is uncertain. The goal of this study was to describe variations in nutritional practices between different countries, professions and types of hospitals, as well as between ulcerative colitis (UC) and Crohn's disease (CD).

Methods: In this cross-sectional study, a novel questionnaire was distributed in the ECCO Congress 2022 and via ECCO country representatives.

Results: The survey was completed by 313 participants. In total, 68% of the respondents were physicians. No specific nutritional screening tool was used by 45% of respondents. Almost a quarter of respondents reported less than 25% of patients being assessed by a dietitian in the first 3 days of a flare. The most common form of nutritional therapy was oral nutritional supplements (ONS) with easy-to-digest food. Total parenteral nutrition (TPN) was used by 10% of respondents for UC patients and 7% for CD. Energy intake, stool frequency and inflammatory biomarkers were the most common factors in determining when to change nutritional therapy. There were significant differences between different countries and health care professions for all the outcomes (P < 0.05). Nutritional management did not generally vary according to hospital type (university vs. general). During the first 3 days of a flare, a diet consisting exclusively of ONS was significantly more frequently used for CD than UC (P = 0.018). Otherwise, similar nutritional therapy strategies were reported for CD and UC, including using TPN to a similar extent.

Conclusion: There is significant variation in nutritional management practices. Country is the main determinant of differences in practice.
