Weekly oral vitamin K prophylaxis in Denmark

Area of Science:

• Neonatal Health
• Pediatric Pharmacology
• Public Health Interventions

Background:

• Vitamin K deficiency bleeding (VKDB) is a serious risk for newborns.
• Traditional intramuscular vitamin K prophylaxis has been standard, but oral routes are explored for ease of administration.
• Understanding the efficacy and compliance of oral vitamin K is crucial for neonatal care guidelines.

Purpose of the Study:

• To evaluate the effectiveness of oral vitamin K prophylaxis in preventing VKDB.
• To assess parental compliance with a weekly oral vitamin K regimen for infants up to 3 months of age.

Main Methods:

• A large cohort study in Denmark involving over 500,000 live births.
• Implementation of a 2 mg oral phytomenadione dose at birth, followed by weekly 1 mg doses administered by parents until 3 months for breastfed infants.
• Surveillance for VKDB cases through pediatric department questionnaires and national patient register checks.

Main Results:

• No cases of VKDB were identified, indicating an incidence of 0-0.9 per 100,000 live births.
• Parental compliance was high, with 94% of infants completing the recommended prophylaxis course.
• The study involved approximately 396,000 neonates receiving oral prophylaxis at birth.

Conclusions:

• Weekly oral vitamin K supplementation is an effective prophylactic measure against VKDB in the first three months of life.
• The oral route demonstrated good parental compliance, suggesting feasibility for widespread adoption.
• This approach offers a viable alternative for VKDB prevention in newborns.
