Newborn Vitamin K Prophylaxis and the Risk of Bleeding – JAMA
JAMA shared a post on LinkedIn about recent articles, adding:
“A study in JAMA of more than 5 million US births indicates that more infants are not receiving intramuscular hashtag VitaminK at birth, despite its routine use to prevent vitamin K deficiency bleeding.
Nonreceipt of intramuscular VitaminK at birth increased from about 3 percent in 2017 to nearly 7 percent in 2025.
The study found higher risks of bleeding, intracranial (within the brain or skull) bleeding, and death with a bleeding diagnosis among infants who did not receive vitamin K, consistent with findings from a separate study in Sweden published in JAMA Pediatrics.
These data support the public health importance of maintaining vitamin K prophylaxis at birth.”
