Immunization status of chronically ill children
1University of Houston, TX 77204-3251.
Insights
Chronically ill children in specialty clinics had lower immunization rates (72%) compared to healthy children (85%). Targeted interventions are crucial to improve vaccination compliance in vulnerable pediatric populations.
Area of Science:
- Pediatrics
- Public Health
- Immunology
Background:
- Vaccination is critical for preventing childhood diseases.
- Chronically ill children may face barriers to maintaining up-to-date immunization schedules.
- Assessing immunization status in specialty clinics is essential for public health.
Purpose of the Study:
- To compare immunization rates between chronically ill children in specialty clinics and healthy children in an acute care setting.
- To identify factors associated with immunization compliance in pediatric patients.
Main Methods:
- Parent-administered questionnaires were used to collect immunization data from 103 chronically ill children and 52 healthy children.
- Immunization rates were compared between specialty clinics and an acute care clinic.
- Statistical analysis was performed to assess associations between clinic type, patient age, and immunization compliance.
Main Results:
- The overall immunization rate was 72% in specialty clinics versus 85% in the acute care clinic (P = 0.118).
- The neurology clinic showed a significantly lower immunization rate (55%) compared to the control group (P = 0.014).
- Older children (≥48 months) in specialty clinics demonstrated better overall compliance (79%) than younger children (60%) (P = 0.057).
Conclusions:
- Chronically ill children in specialty clinics, particularly those in neurology, may have suboptimal immunization coverage.
- Age appears to be a factor in immunization compliance among specialty clinic patients.
- Enhanced efforts are required to ensure chronically ill children receive recommended vaccinations.
Abstract:
The immunization status of 103 chronically ill children attending five specialty clinics, and 52 otherwise healthy children attending an acute care clinic, was determined using a questionnaire self-administered by parents. The immunization rate in specialty clinics was 72%, compared with 85% in the acute care clinic (P = 0.118). Only the neurology clinic rate (55%) differed significantly from the control (P = 0.014). In patients age 48 months or older, there was a significant association between clinics and overall compliance (P = 0.003). Older specialty clinic patients (79%) tended to be more compliant compared to their younger counterparts (60%) (P = 0.057). No significant association was noted between immunization compliance and source of primary care services or intensity of use of services. Greater efforts are needed to identify underimmunized chronically ill children and to provide the means to bring them into compliance.
