Organ dysfunction score for pregnant and early postpartum patients
Official title: Development and Validation of an Obstetric Organ Dysfunction Score to Predict Mortality in Intensive Care Unit: A Multicenter, Prospective, Cohort Study
Run by Argentinian Intensive Care Society · NCT07068022 · Data updated 2026-11-12
This project will test a pregnancy‑adjusted SOFA score (SOFA-OBS) and whether pulse oximeter oxygenation can replace arterial measures to predict mortality in pregnant or up to 3-day postpartum adults admitted to the ICU.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18 years) who are pregnant at any gestational age or ≤3 days postpartum, require ICU admission for ≥24 hours, and consent to participate are the intended candidates.
✕Probably not a fit
Non-pregnant patients, those >3 days postpartum, patients with ICU length of stay under 24 hours, pediatric patients, or those in whom pulse oximetry is unreliable are unlikely to benefit from this protocol.

What this trial studies
This is an observational cohort of adult pregnant or ≤3-day postpartum patients admitted to the ICU, aiming to enroll about 130 participants. Investigators will collect routine clinical data and laboratory results already obtained by ICU teams and will not perform additional interventions. They will develop a modified SOFA score (SOFA-OBS) calibrated for obstetric physiology and compare its ability to predict ICU mortality against the standard SOFA. The study will also compare non-invasive pulse oximeter-based oxygenation measures with arterial oxygenation measures to see if the non-invasive approach performs similarly.
Why it matters
Potential benefit: If successful, a validated pregnancy-adjusted organ dysfunction score and reliable pulse oximetry approach could help clinicians recognize high-risk obstetric ICU patients earlier and reduce the need for arterial blood gases.
How similar studies have gone: The standard SOFA score is well validated for mortality prediction in general adult ICU populations, but adapting and validating it specifically for pregnant and early postpartum patients is relatively novel with limited prior validation.
