Aetiology and trends of rates of stillbirth in a tertiary care hospital in the north of India over 10 years: a retrospective study.

OBJECTIVE: To analyze the aetiology of stillbirth and their changing trends in a single tertiary care referral institute of northern India over a 10 year period (2007-2016).

DESIGN: Retrospective study.

SETTING: Tertiary care hospital in the north of India.

SAMPLE: Medical records of all mothers who delivered a stillborn at the institute.

METHODS: Data was collected from monthly and annual perinatal audits and causes of stillbirths were classified using Simplified CODAC classification. Annual reduction rate was calculated by linear regression analysis and Cusick test for the changing trends over nine years.

MAIN OUTCOME MEASURES: Out of a total of 54160 births, 3678 babies were stillborn. The annual stillbirth rate has reduced significantly from 73.6 to 62.0 per 1000 total births over nine years with average annual reduction rate of 1%. The most common causes of stillbirths were hypertensive disorders of pregnancy (27.6%), antepartum hemorrhage (19.5%), and congenital anomalies (9.3%).

CONCLUSION: The annual reduction rate (1%) of stillbirth remains low. The aetiology of stillbirths remains unchanged over a 10-year period and hypertensive disorder of pregnancy remains the single most preventable cause of stillbirth. This article is protected by copyright. All rights reserved.
