Clinical profile and outcome of obstetric ICU patients. APACHE II, SOFA, SAPS II and MPM scoring systems for prediction of prognosis

Objectives: To evaluate the various scoring systems, APACHE II, SOFA, SAPS II and MPM for the prediction of prognosis of the obstetric critically ill patients admitted in a well supported ICU unit. Material and methods: A prospective, observational study was conducted among all the obstetric patients admitted to the ICU between October 2011 and December 2012, during a period of 15 months. The data collected were of three categories: demographic, obstetric and ICU related. Results and Analysis: The patients admitted in the postpartum period (n = 28, 53.84%) were more than the antenatal admissions (n = 24, 46.16%). 32.69% of admissions were in the third trimester. The most common mode of delivery was emergency caesarean section (n = 27/40, 67.5%). Total caesarean deliveries were 35/40 = 87.5% in ICU patients. The mortality prediction scores were calculated for 41 patients only as acid blood gas analysis was not available for the rest. Patients required ventilation—51.92%, hemodialysis—19.23%, inotropic support—38.46%, blood transfusion—50%. Analysis of the statistical data for ICU parameters has shown that hospital stay (p = 0.011) and ventilation days (p = 0.014) are significant predictors of maternal outcome. Age (p = 0.789), ICU stay (p = 0.701) and RRT (p = 0.632) are not significant. Among the obstetric ICU admissions, hypertensive disorders of pregnancy (30.76%) was the predominant cause followed by obstetric haemorrhage (23.07%). Discussion: HELLP syndrome and eclampsia (n = 4, 57%) were the major causes of maternal deaths with anaesthetic mishaps accounting for 29% (n = 2). One (14%) death was due to Eisenmenger’s syndrome. In one case of H1N1 admitted with ARDS, caesarean section was done in MICU for worsening respiratory distress. The maternal mortality in this series of cases was 7/52 = 13.46%, excluding the unavoidable cases of maternal death (3 cases brain dead at admission and one cardiac arrest in emergency room), our maternal mortality rate is 3/48 = 6.25%. The predicted mortality as measured by all scoring systems (for 41 patients) was between 17% and 30%. The observed mortality was around 17%. Hence a reduction in mortality of 40% has been achieved due to intensive care. Conclusions: Leading cause of maternal mortality was HELLP syndrome. Hypertensive disorders of pregnancy were the most common cause of admission to ICU. In this study, all the scores were equally significant in predicting maternal mortality. Amongst the interventions done for these patients mechanical ventilation seems to have an influence on the overall outcome.
