Insights
Many parents refuse vitamin K prophylaxis for newborns due to concerns about ingredients and dosage, often influenced by internet information. Prenatal education addressing these specific parental concerns is crucial for improving vitamin K uptake.
Area of Science:
- Pediatrics
- Neonatal Health
- Public Health
Background:
- The American Academy of Pediatrics strongly recommends intramuscular (IM) vitamin K prophylaxis for all newborns.
- Vitamin K deficiency bleeding (VKDB) in newborns, especially late-onset VKDB, can have severe consequences.
- Understanding parental refusal of this vital prophylaxis is essential for improving infant health outcomes.
Purpose of the Study:
- To investigate the factors influencing parents' decisions to refuse IM vitamin K prophylaxis for their newborns.
- To identify the primary concerns and information sources utilized by parents who decline this intervention.
Main Methods:
- A survey was administered to parents intending to refuse IM vitamin K prophylaxis at delivery across various birth settings in a Southeastern state.
- The survey collected data on demographics, parenting choices, and specific concerns regarding vitamin K, including information sources and perceived risks.
Main Results:
- The incidence of refusal was highest in birthing centers.
- Parents refusing vitamin K often also refused other standard newborn interventions like the hepatitis B vaccine and erythromycin eye ointment.
- Common concerns cited were synthetic ingredients, excessive dosage, and potential side effects, with the Internet being the primary information source (70%).
Conclusions:
- Parents refusing IM vitamin K prophylaxis often base their decisions on information found online, focusing on perceived risks related to ingredients and dosage.
- Prenatal education is critical and must proactively address parental concerns identified through online resources to improve acceptance rates of vitamin K prophylaxis.
Objective:
The American Academy of Pediatrics recommends intramuscular (IM) vitamin K prophylaxis for all newborns to prevent vitamin K deficiency bleeding. Given the serious implications of late-onset vitamin K deficiency bleeding, our objective was to examine factors influencing parents' decisions to refuse IM vitamin K prophylaxis.
Methods:
Parents intending to refuse IM vitamin K prophylaxis at delivery were recruited from 5 community hospitals, 1 academic medical center, and 2 birthing centers in a single Southeastern state. Participants completed a written survey including demographics, birth and parenting decisions (eg, breastfeeding), and open-ended questions about their vitamin K information sources, concerns, and knowledge of risks.
Results:
The incidence of refusal was highest at the birthing centers. Fifty-four parents intending to refuse IM vitamin K completed the survey. Most were white (78%), over age 30 (57%), and college graduates (65%). All reported intention to exclusively breastfeed. Most refused hepatitis B vaccine (90%) and erythromycin eye ointment (77%). The most common source of information was the Internet (70%). Concerns included synthetic or toxic ingredients (37%), excessive dose (28%), and side effects (24%). Eighty-three percent of parents reported awareness of risks associated with vitamin K refusal. However, only 6 parents (11%) decided to accept IM prophylaxis.
Conclusions:
This study provides an understanding of the concerns, mindset, and information sources used by parents refusing IM vitamin K. Educating parents about the importance of IM prophylaxis should begin in the prenatal period and must address concerns parents identify on the Internet.
