To classify infant deaths, the investigators included only ICD-10 diagnoses classified as P-codes to capture deaths occurring in the first 28 days after birth, but excluding congenital problems that are incompatible with life or that usually cause early death.
The researchers reported that they had no conflicts of interest; the study was funded by a research enhancement program award from the Texas Women’s University Office of Research and Sponsored Programs.
