Overview

Nationwide cohort study evaluates vitamin K administration and its impact on bleeding in newborns, indicating the need for continued education.

Key Points

  • To analyze trends in newborn vitamin K prophylaxis and its correlation with bleeding events during infancy.
  • Nationwide cohort study of 2,020,302 live births from January 1, 2003, to December 31, 2021.
  • Linked data from the Swedish Medical Birth Register and national registers.
  • Utilized logistic regression to calculate adjusted odds ratios (aORs) for bleeding risk.
  • Infants without vitamin K received at birth had 1.52-fold higher odds of bleeding (aOR, 1.52; 95% CI, 1.27-1.81).
  • Infants without vitamin K had 2.91-fold higher odds of intracranial bleeding (aOR, 2.91; 95% CI, 2.13-3.96).
  • Rate of nonreceipt of vitamin K increased from 0.66% in 2006 to 1.50% in 2021.
