Objectives: To study clinical profile of obstetric patients admitted to intensive care unit and to analyze the relation of demographic factors like age, parity, literacy level, socio economic status, APACHE 2 score and level of delay with fetomaternal outcome. Design: Prospective Cross sectional Observational Setting and Population: Obstetric Admissions to ICU of tertiary hospital in North India Methods: After admission to ICU a detailed history, analysis of basic demographic variables along with level of delay was done. APACHE II score was calculated. These parameters were correlated with fetomaternal outcome. The Chi-square test was used to compare categorical variables. The one-way analysis of variance was used to compare the continuous variables among the strata with Tukey’s post hoc test. Outcome: Prolonged ICU stay, maternal mortality, perinatal morbidity, perinatal mortality and long hospital stay. Results: Incidence of obstetric ICU admission was 0.77%. Mean age was 26.03years. Most common indication of ICU admission was obstetrical hemorrhage (37.1%) followed by hypertensive disorders of pregnancy (25.8%). Type 1 delay was the most common followed by type 2 delay. Mean APACHE II score was 14.77±6.85. Observed mortality rate (30.6%) was found to be higher than predicted mortality rate (25%). APACHE II score was significantly high in the presence of level 1 (p=0.003) and level 2 delay (p=0.0001). Also, it was significantly increased with the duration of delays. Conclusion: Unbooked and referred cases had high incidence of ICU admission. Presence of delay was associated with poor outcome
