Aim: To compare maternal outcomes in critically ill patients using SOFA, q SOFA and SOS scoring systems. Material and Methods: The present hospital based observational study was conducted at Department of General Medicine and Casualty, Rajmata Vijaya Raje Scindia, Bhilwara, Rajasthan from January 2023 to March 2024. As it is a time bound study, we were able to recruit 81 patients during the study period. A detailed general and obstetric examination was done. Relevant laboratory and imaging tests were undertaken and blood samples drawn for hematological examination. QSOFA, SOFA and SOS was applied prospectively in enrolled patients. Organ failure assessment and monitoring was done at 48hrs and discharge/mortality was recorded. Results: In the present study; mortality rate was (n=18, 22.22%). Serum urea showed a statistically significant difference between survivors and non-survivors (p=0.006).For our study population, a threshold of SOFA ≥ 6 had the best combination of sensitivity (92.5%) and specificity (66.8%) for critical care admission and maternal mortality. For SOS, a cut-off value of ≥ 6 gave best sensitivity (68.2%) and specificity (60.4%) for the same. qSOFA≥1.7 was far more predictive of patient’s critical condition as well as mortality compared to SOS with sensitivity 86.4% and specificity 61.9%. Conclusion: SOFA was best to decide critical care admission and predict mortality in pregnancy-associated sepsis when tested in a severe morbidity and high mortality clinical setting. The q SOFA however is more predictive than SOS for maternal mortality and ICU admission.
