Obstetric patients requiring high-dependency unit admission in a tertiary referral centre.

Aim: To analyze the HDU requirement in an obstetric population in terms of utilization rate, indications for admission, interventions required and gestational outcome. Setting and Design: A retrospective observational study was carried out from May 2007 to May 2011 in the Dept. of Obstetrics and Gynecology and HDU of IPGME and R, Kolkata. Materials and Methods: Data related to obstetric history, pre-existing medical problems, indications for HDU admission, interventions required, length of stay and outcome were collected and results were analyzed. Results: Our obstetric HDU utilization rate was 11.2 per 1000 deliveries. Out of total 57 subjects 48 had no prior antenatal care. Majority (68.42%) admitted in HDU with only obstetric reasons, while 31.57% required HDU for pre-existing medical diseases. The major obstetric indications were septicemia (35.08%), PPH (29.08%) and hypertension was observed in 21.05% of women. Other less common causes included post surgical acute kidney injury, APH, chrioamnionitis and pyelonephritis. Half of the women with pre-existing medical disease had cardiovascular problems. Patients with medical diseases had more pre-term labor (10 vs 5; P ≤ 0.05), respiratory failure (9 vs 2; P ≤ 0.05), cardiac failure (7 vs 1; P ≤ 0.05), duration of stay more than 10 days (15 vs 6; P ≤ 0.05), fetal growth restriction (6vs 3; P ≤ 0.05) and prolonged recovery time. Maternal mortality was 12.28% and fetal mortality was 17.54%. Conclusion: Early screening of high risk mothers, vigilant antenatal care and proper maintenance of asepsis during delivery and postpartum period can reduce HDU utilization rate and can result in healthier outcome.
