Background: Preeclampsia is one of the dreadful complication of pregnancy, a leading cause of maternal morbidity and mortality. To assess organ dysfunction clinically a Sequential Organ Failure Assessment Score (SOFA score) was developed. This study was done with the objective of correlation of maternal mortality and morbidity in pre eclampsia patients using modified SOFA (m SOFA) score. Methods: This was a prospective study which was carried out for a period of 1 year in the Department of obstetrics and gynaecology in a tertiary care Medical college hospital. The study enrolled a total of 100 patients. A structured Proforma was used to collect the relevant data and detailed history was taken. Duration of hospital stay, maternal and perinatal outcomes, maternal complications such as abruption, DIC, HELLP, Sepsis, eclampsia, maternal mortality were observed and assessed. Results: The average age was 30 yrs and most of them were >37 weeks of gestation. Anaemia was the most common comorbidity among them. The mortality rate was 12%. The greater the score the more were the complication and also the need for hospital stay.The study inferred a significant association between the mSOFA score and maternal mortality and complications of preeclampsia like abrubtion, eclampsia. Conclusion: The difference in the mSOFA score in the pre eclampsia patients were assessed in this study. The mortality and the morbidity increases with increase in the SOFA score. So it can be concluded that obstetrically modified SOFA scores has an increased significance and predictability of mortality in pre eclampsia patients.
