Comparison of Sequential Organ Failure Assessment (SOFA) and Sepsis in Obstetrics Score (SOS) in Women with Pregnancy-Associated Sepsis with Respect to Critical Care Admission and Mortality: A Prospective Observational Study.

OBJECTIVE: We aimed to determine performance of sequential organ failure assessment (SOFA) and Sepsis in Obstetrics Score (SOS), in women with pregnancy-associated sepsis (PAS) with respect to critical care admission and mortality.
METHODS: Obstetric patients with PAS fulfilling any 2 of the quick SOFA (qSOFA) criteria were enrolled as cases. The various parameters of SOFA and SOS were recorded at admission and compared for outcomes.
RESULTS: Critical care was required in 32 (50.7%) patients and associated mortality was high (31.7%). For our study population, a threshold of SOFA ≥ 6 had the best combination of sensitivity (84.4%) and specificity (61.3%) for critical care admission. For SOS, a cut-off value of ≥ 6 gave best sensitivity (64%) and specificity (40%) for the same.
CONCLUSIONS: SOFA was far more predictive of patient's critical condition as well as mortality compared to SOS. SOFA was superior to SOS in determining critical care admission and mortality for PAS. © Federation of Obstetric & Gynecological Societies of India 2020.
