AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults admitted to an intensive care unit (ICU) who are expected to stay at least 24 hours. Waist size and height must be measurable.
- Age
- 18 years or older
- Sex
- All sexes can join.
- Disease stage
- Adults admitted to an ICU with an expected stay of 24 hours or more.
- Biomarker or test result
- Waist circumference and height must be measurable within 24 hours of admission.
Main reasons for not taking part
- Under 18 years old
- ICU stay shorter than 24 hours
- Waist or height cannot be measured (for example severe edema, abdominal wound, or morbid obesity that prevents measuring)
- Pregnancy
- Readmission to the ICU (only the first admission counts)

- Original description
This study investigates whether Body Roundness Index (BRI), an anthropometric measure derived from waist circumference and height, can predict mortality in adult intensive care unit (ICU) patients. BRI captures central adiposity and body fat distribution more accurately than Body Mass Index (BMI). In this prospective multicenter cohort study, BRI will be measured at ICU admission and its association with ICU mortality, 28-day mortality, hospital mortality, mechanical ventilation duration, ICU length of stay, and acute kidney injury will be evaluated. The predictive performance of BRI will also be compared with BMI.Read full original descriptionShow less
Body Roundness Index as a Predictor of Mortality in Adult Intensive Care Unit Patients: A Prospective Multicenter Cohort Study (BRI-ICU)
This study investigates whether Body Roundness Index (BRI), an anthropometric measure derived from waist circumference and height, can predict mortality in adult intensive care unit (ICU) patients. BRI captures central adiposity and body fat distribution more accurately than Body Mass Index (BMI). In this prospective multicenter cohort study, BRI will be measured at ICU admission and its association with ICU mortality, 28-day mortality, hospital mortality, mechanical ventilation duration, ICU length of stay, and acute kidney injury will be evaluated. The predictive performance of BRI will also be compared with BMI.
Inclusion: Age ≥18 years; ICU admission with expected stay ≥24 hours; Waist circumference and height measurable within 24 hours of admission.
Exclusion: Age <18 years; ICU stay <24 hours; Missing or unmeasurable anthropometric data (e.g., severe edema, abdominal wound, morbid obesity precluding measurement); Pregnancy; Readmission (only first ICU admission included).
