Outline

• Introduction • Study Purpose • Methodology • Results • Implications 1

Introduction

• Newborn deaths account for 40% of under- five mortality (MDG- 4).

• Reducing early neonatal mortality is necessary to achieve MDG- 4.

2

Introduction ctd…

• Two-thirds of child deaths occur in the first month of life. Of these, more than two thirds die in their first week. Among those in the first week, two-thirds die in the first 24 hours of life. • Unless neonatal mortality is greatly reduced it is not possible to achieve millennium development goal 4 .

3

Introduction ctd…

• In Malawi, an increase in perinatal mortality estimated at 40/1000 (MDHS 2010) • Few studies done.

• These data are essential to effectively plan how to reduce perinatal mortality.

4

Objectives

• To establish an estimate of perinatal mortality at Chiradzulu District Hospital.

• To identify associated risk factors, and to determine causes of perinatal deaths. 5

Methodology

Design:

A cross sectional prospective review of records.

Setting:

Chiradzulu district hospital, labor ward and postnatal ward.

Inclusion criteria:

Records of mothers who received antenatal care at any health facility but delivered at the district hospital from 28 weeks to term. 6

Methodology ctd…

Data collection: A data record form:

was used to collect maternal and neonatal information

Data analysis

• Stata version 11.0 was used • Univariate analysis was computed to determine the association between outcome (perinatal death) and independent variables.

7

Methodology ctd… Ethical consideration:

• Study approval - Norway Regional Committee for Medical Research Ethics & College of Medicine Research and Ethics Committee, Malawi. • Written permission from the District Health Officer - Chiradzulu District Hospital 8

Implications

• Reinforce and improve health workers’ abilities to properly monitor women in labor at all levels of care for early identification and management of complications.

• Encourage women to start antenatal care early for them to adhere to the four recommended antenatal visits.

• Improve health workers ability in basic resuscitation, as well as care of low birth weight babies. 22

Implications ctd…

• Referral of women with very preterm labor (28 to 32 weeks) to deliver in a facility with neonatal intensive care. • Pregnant women and communities should have sufficient information on obstetric complications to seek health care in time. 23
