Introduction and Aim: Critically ill obstetric women in the obstetrics high dependency unit are a challenging situation to the obstetricians.
The frequency of obstetric admissions that require admissions for critical care in the ICU and HDU is on the rise. Overall the obstetric admission in ICU in our institute varies from 4-6% of the deliveries. This study
attempts to evaluate the occurrence, indications, progression, interventions and outcomes of these obstetric patients admitted in the obstetric HDU.

Materials and Methods: This is prospective observational study of obstetric patients admitted in the obstetric HDU in one year from January 2019 to December 2019 at Bharati Hospital and Research
centre attached to Bharati Vidyapeeth Medical college Pune, Maharashtra. All the admissions in a dedicated 6 bed HDU were included in the study. The course of events and outcomes were documented and tabulated. The data will be analysed against the total
no of deliveries for the study period. Incidence and prevalence of various obstetric conditions requiring HDU support was studied.

Results: In total 414 patients required HDU care during the study duration. 19.11% of all the births during the year required HDU care indicating a high number of high risk pregnancy case load. Maximum
admissions to HDU were in second half of gestation or postpartum. Most common indication for admission to HDU was preeclampsia 185 patients (44.68%). Maximum patients (55.31%) were referred from other
nursing homes. 35 patients had associated heart disease, 27 had diabetes, 26 patients had associated other endocrine disease.

Conclusions: A high incidence of Obstetric HDU admissions was observed in the study as it was conducted in a tertiary care referral teaching hospital with dedicated Obstetric HDU and ICU. nAn increasing trend of Obstetric admissions is seen due to an increased incidence of high risk pregnancy with maternal age, assisted conception, obesity and
underlying medical conditions acting as a major confounding factors.Obstetric HDU will go a long way in prevention of maternal morbidity and mortality.
