The aim of this study was to determine factors that are associated with adherence to the Canadian nutrition support clinical practice guidelines (CPGs).
We conducted a secondary analysis of data from a prospective observational cohort study of nutrition support practices in 58 intensive care units (ICUs) across Canada, grouped into 50 clusters.

We applied hierarchical modeling techniques to examine the impact of various hospital, ICU, and patient factors on EN adequacy.
The overall average EN adequacy was 51.3% (SE, 1.8%). In a multiple regression analysis, after adjusting for varying days of observation, hospital type (academic 54.3% vs community 45.2%, P
