Definition and timing of neonatal deaths<br />

The neonatal period refers to the first 28 days of life (Figure 2.1). The early neonatal period<br />

is the first 7 days after birth, and the late neonatal period extends from 7 days to 28 completed<br />

days. The first day of life, the 24 hours following the birth, is typically called “day 1”<br />

in clinical practice, or “day 0” in surveys and vital registration. In this guide we refer to<br />

the first day of life as “day 1”, and we refer to days 1–7 as the “early neonatal period”,<br />

days 8–28 as the “late neonatal period”, and days 1–28 as the “full neonatal period” (26).<br />

Deaths on the day of birth (day 1) and in the first week of life are particularly important<br />

because they account for a large number of deaths that can be targeted by interventions<br />

around the time of birth. Around three quarters of neonatal deaths are estimated to occur<br />

during the first week of life (26). Many late neonatal deaths occur at home and may not<br />

be captured in facility-level records, though they may be captured by CRVS systems with<br />

variable information on cause of death and relevant details. When deaths do occur in<br />

health-care facilities, whether in the neonatal unit, postnatal ward or paediatric ward, they<br />

should be documented and included in the audit process. Deaths that occur in the community<br />

after discharge from a health-care facility may also be considered for inclusion in<br />

the death review process if enough information is available. The neonatal mortality rate is<br />

expressed at the population level as a rate per 1000 live births (Table 2.1).<br />
