Prospective multicenter study to validate the gastrointestinal dysfunction score (GIDS) in intensive care patients: Study protocol for Part A of the international GUTPHOS study

The present study aims to validate the recently developed Gastrointestinal Dysfunction Score (GIDS) in a multicenter, prospective cohort of consecutive adult patients admitted to intensive care units (ICU).
