Body Roundness Index and Mortality in ICU Patients (BRI-ICU)
Body Roundness Index as a Predictor of Mortality in Adult Intensive Care Unit Patients: A Prospective Multicenter Cohort Study (BRI-ICU)
Studie Overzicht
Toestand
Gedetailleerde beschrijving
Body Roundness Index (BRI) is calculated using waist circumference and height, and reflects central adiposity more precisely than BMI. Despite growing evidence supporting BRI as a cardiovascular and metabolic risk predictor in general populations, its prognostic value in critically ill patients remains unexplored.
In this prospective multicenter cohort study, adult patients admitted to participating ICUs will be enrolled. Waist circumference will be measured using a standardized protocol (supine position, iliac crest landmark, end-expiration, inelastic tape, 0.1 cm precision) within 24 hours of ICU admission. BRI will be calculated using the formula: 364.2 - 365.5 × √(1 - ((WC/2π)² / (0.5×height)²)).
The primary outcome is ICU mortality. Secondary outcomes include 28-day mortality, hospital mortality, mechanical ventilation duration, ICU length of stay, and new acute kidney injury (KDIGO stage ≥2). The shape of the BRI-mortality relationship will be assessed using restricted cubic splines. BRI and BMI will be compared head-to-head for discriminative performance. Subgroup analyses will include sepsis patients to evaluate whether BRI resolves the obesity paradox observed with BMI.

Adult ICU Patients
Adult patients (≥18 years) admitted to the intensive care unit with an expected stay of ≥24 hours.
Waist circumference and height are measured within 24 hours of admission to calculate Body Roundness Index (BRI) and BMI.
Patients are followed for ICU mortality, 28-day mortality, hospital mortality, mechanical ventilation duration, ICU length of stay, and acute kidney injury (KDIGO stage ≥2).
No intervention is applied; this is a prospective observational cohort.
