Analysis of perinatal deaths and ascertaining perinatal mortality trend in a hospital

Perinatal mortality rate is very high in developing countries including Nepal. Analyzing perinatal deaths help in identifying preventable factors thus help in reducing it. Analysis of causes of perinatal deaths over a period in a hospital will help to identify the perinatal mortality trend and preventable factors thus help in taking corrective measures to reduce the perinatal mortality rate. The aim of the study is to analyse perinatal deaths and ascertain perinatal mortality trend of Kathmandu Medical College Teaching hospital in the last 8 year period.

Stillbirths and early neonatal deaths from 2002 to 2011 are collected from the register book of the labour room, special care baby unit and operation theatre of the hospital. Perinatal mortality rate and extended perinatal mortality rates are calculated and perinatal deaths were classified according to Wigglesworth's classification. Trend of Perinatal and Extended Perinatal mortality rates, stillbirth rates and early neonatal death rates among 5 perinatal death audits of the hospital were compared.

In the first perinatal death audit (Oct '02-Sept '03) perinatal mortality rate (PMR) was recorded as 30.7 per 1000 births and extended perinatal mortality rate (EPMR) as 47.9 per 1000 births, where as in the fifth perinatal death audit (Apr '10-Mar '11) PMR was recorded as 14.4 per 1000 births and EPMR as 19.6 per 1000 births. In Wigglesworth's classification, in the first perinatal death audit, most of the perinatal deaths were in group IV (41%) reflecting more asphyxial deaths however in fifth audit, group III mortality (41%) was highest indicating death of low birth weight or preterm babies. In the first audit, stillbirth rate (SBR) excluding <1 kg was 18.1 per 1000 births and early neonatal deaths (ENND) excluding <1 kg was 12.9 per 1000 live births. In the fifth audit, SBR (excluding <1 kg) and ENND rate (excluding <1 kg) were 7.1 per 1000 births and 7.2 per 1000 live births respectively reflecting declining trend of both SBR and ENND rate in the hospital.

Distinct declining trend in PMR, EPMR, SBR and ENND rates at KMCTH were noted. As asphyxial deaths have been reduced significantly, more intensive efforts are needed to prevent premature births with care of preterm and very low birth weight babies.
