Parents decline vitamin K shots for newborns due to beliefs, child welfare concerns, and external influences. This hesitancy mirrors broader concerns about medical interventions for children.
Area of Science:
- Pediatrics
- Public Health
- Qualitative Research
Background:
- Newborns are at risk for vitamin K deficiency bleeding (VKDB).
- Intramuscular (IM) vitamin K prophylaxis is a standard preventative measure.
- Parental decisions to opt out of IM vitamin K impact public health strategies.
Purpose of the Study:
- To investigate the reasons behind parents opting out of IM vitamin K prophylaxis for their newborns.
- To understand the influencing factors in parental decision-making regarding newborn vitamin K administration.
Main Methods:
- Qualitative study employing semistructured interviews with 15 families.
- Thematic analysis was used to identify key themes in parental decision-making.
- Study conducted in the Otago/Southland region of New Zealand.
Main Results:
- Parental decisions were influenced by beliefs and values (philosophy, spirituality).
- Concerns about child welfare, including pain and potential side effects, were significant.
- External factors such as family, friends, media, and healthcare professionals played a role.
- Many parents expressed broader hesitancy towards medical interventions.
Conclusions:
- Parental decisions to opt out of IM vitamin K are multifactorial.
- Findings highlight parallels with decisions regarding other childhood interventions.
- Understanding these factors is crucial for addressing vaccine hesitancy and improving informed consent processes for newborn care.
