PMID 39607164WHAT IT FOUND
Pernambuco's neonatal mortality rate fell between 2000 and 2020, with an average annual reduction of 2.9%, but trends varied by health region.
This is population surveillance, not evidence that any care change worked.
Key findings
01From 2000 to 2020, 34,863 neonatal deaths were recorded in Pernambuco, with an average total neonatal mortality rate of 11.5 per 1,000 live births.
02The total neonatal mortality rate in Pernambuco showed a decreasing trend between 2000 and 2019, with an average annual percent change of -2.9.
03Early neonatal mortality declined with an average annual percent change of -3.2, and late neonatal mortality declined with an average annual percent change of -0.8.

What it does not show
The study used death and birth records, so it can only show what was recorded; missed or incomplete entries could affect the rates. It looks at population rates over time, not individual patients or care processes, so it cannot show what caused the decline or what nursing action helped. Trends differed by health region, so statewide averages may hide local increases or slower declines.
The easy way to misread this
Do not read the falling mortality rate as proof that a specific care programme worked. The study used population records over time, and it reported no change or accentuation in trends after the Mãe Coruja Pernambucana Program was implemented.
