Rationale: Medical nutritional therapy (MNT) is a key component of patient care in hospital settings. Over the past two decades, patterns of nutritional support, including oral nutritional supplements (ONS), enteral nutrition (EN), and parenteral nutrition (PN), may have evolved across hospital wards and world regions reflecting greater DRM awareness, changes in clinical practices and guideline adherence.

Methods: We analyzed data from 12295 hospital wards worldwide (grouped as internal medicine (n = 6229), surgery (n = 2977), and other specialty units (n = 3089) participating in nutritionDay from 2006 to 2024. The use of ONS, EN, and PN was analyzed over time, with comparisons across geographic regions (Europe, Asia, America A and America B) and ward types. Annual linear slopes were calculated for each region and specialty. Trends were tested using t-Test, with p<0.001 considered significant. All analyses were performed using R (v4.5.1).

Results: Overtime ONS use increased significantly in all regions, while EN decreased in all regions, and PN increased only in AMR B, as shown in the figure. By specialty, ONS increased significantly in Europe (internal medicine +1.30, surgery +0.65, others +1.10), AMR A (internal medicine +0.95, surgery +1.30), AMR B (surgery +0.53, others +0.46), and Asia (internal medicine +1.15, others +1.15. EN declined in Europe (internal medicine −0.43, surgery −0.43, others −0.74), AMR A (surgery −0.22), AMR B (others −0.46), and Asia (internal medicine −0.55). PN decreased in Europe (surgery −0.26, others −0.21) and Asia (internal medicine −0.44, surgery −0.70).

Conclusion: Overall, MNT trends show increased ONS use and reduced EN/PN across world regions and specialties. The underlying factors driving these trends are still unclear and need further investigation, such as analyses of guideline adoption, patient characteristics, or resource availability.
