Objectives: This study aimed to identify the outcomes currently measured by Swiss dietitians in MNTs for IBS and assess their documentation using the Academy of Nutrition and Dietetics Health Informatics Infrastructure (ANDHII) database, which is based on NCPT.
Methods: Six Swiss dietitians documented their IBS patient consultations in ANDHII for eight weeks. Descriptive analyses were performed to evaluate the documented outcomes.
Results: Documented outcomes primarily related to gastrointestinal symptoms, nutrient and food group intake, weight changes, and nutrition-related quality of life. Patient-reported outcomes (PROs) accounted for 62%, while no patient-reported experiences (PREs) were recorded. Compared to 83 outcomes used in IBS research, only 11 were documented in practice. Many research outcomes that were not recorded in ANDHII were not part of the NCPT.
Conclusion: Outcome measurement in IBS relies heavily on PROs due to the lack of objective markers. However, the NCPT does not fully accommodate PROs, limiting its suitability for IBS documentation. To improve MNT effectiveness assessment, the NCPT should be expanded to include PROs and PREs. Additionally, a consensus on key outcomes and a standardized documentation system for all dietitians are essential to enable data aggregation and evaluation [ Introduction: Dietitians increasingly need to demonstrate the effectiveness of their medical nutrition therapies (MNTs). This requires outcome management based on standardized terminology, such as the Nutrition Care Process Terminology (NCPT), and a consensus on relevant outcomes. However, for irritable bowel syndrome (IBS), no such consensus exists. A standardized outcome was developed based on IBS studies, but it remains unclear which outcomes are measured in daily dietetic practice and whether the NCPT is suitable for documentation.
