Summary
Maintaining consistent care with a child's initial healthcare provider significantly boosts immunization rates. Early and continuous engagement with a medical home is crucial for ensuring children stay up-to-date on vaccinations.
Area of Science:
- Pediatrics
- Public Health
- Health Services Research
Background:
- Continuity of care is vital for consistent health management.
- Understanding its impact on childhood immunization is essential for public health initiatives.
Purpose of the Study:
- To investigate the association between continuity of care at the initial source and immunization coverage in young children.
- To determine if exclusive use of the initial provider impacts immunization rates.
Main Methods:
- A cohort study design was employed with 641 children under 3 months old.
- Data were collected from medical records and the New York City Department of Health Citywide Immunization Registry.
- Immunization status was assessed as cumulative, age-appropriate, and up-to-date at 18 months (UTD18).
Main Results:
- Less than half (46%) of children maintained continuity of care at their initial provider by 18 months.
- Children using other providers alongside their initial source had higher immunization rates.
- Continuity of care showed a threshold effect starting at 12 months, significantly increasing the likelihood of being up-to-date on immunizations.
Conclusions:
- Continuity of care at the initial source positively impacts immunization coverage, even with supplementary care elsewhere.
- Interventions encouraging sustained use of a medical home for the first two years are recommended to improve vaccination rates.
