Vaccine-preventable disease susceptibility in a British paediatric assessment unit

Area of Science:

• Pediatric secondary care
• Public health
• Immunization practices

Background:

• Under-immunization in children poses risks for vaccine-preventable diseases (VPDs).
• Paediatric secondary care settings present opportunities to identify and address immunization gaps.
• Effective identification strategies are crucial for timely catch-up immunizations.

Purpose of the Study:

• To assess the impact of simple interventions on identifying under-immunized children.
• To evaluate the facilitation of catch-up immunizations in a pediatric secondary care center.
• To measure changes in vaccine-preventable disease susceptibility burdens before and after intervention.

Main Methods:

• Utilized a population-based child health database for two cohorts (200 admissions each).
• Implemented routine printing of immunization histories and staff awareness initiatives.
• Calculated vaccine-preventable disease (VPD) susceptibility burdens and assessed case notes.

Main Results:

• 14% of admitted children were under-immunized; 27% of these were over five years behind schedule.
• Under-immunized children had significant VPD susceptibility burdens, averaging over 1,000 days.
• Positive identification of under-immunized children increased by 40% (p=0.002) post-intervention.

Conclusions:

• Children in British secondary care exhibit substantial burdens of vaccine-preventable disease susceptibility.
• Routine database printouts significantly improved the identification of under-immunized children.
• Despite improved identification, catch-up immunization rates did not show a corresponding increase.
