National Inpatient Immunization Patterns: Variation in Practice and Policy Between Vaccine Types

Area of Science:

• Pediatric Healthcare
• Public Health
• Vaccinology

Background:

• Many hospitalized children are underimmunized, highlighting gaps in current inpatient vaccination systems.
• Little is known about the national landscape of pediatric inpatient immunization practices.
• Understanding these practices is crucial for improving vaccination rates in hospitalized youth.

Purpose of the Study:

• To describe national pediatric inpatient immunization practices.
• To determine variations in vaccination support for adolescent, childhood, and influenza vaccines.
• To identify factors influencing inpatient vaccination delivery.

Main Methods:

• An electronic survey was distributed to leaders in pediatric hospitals nationwide.
• Hospitals reported on practices supporting vaccination for various vaccine types.
• Statistical analyses (ANOVA, chi-squared) compared practices across vaccine types; qualitative data were content-analyzed.

Main Results:

• Influenza vaccine delivery is supported by more practices (average 5.1) than childhood (1.5) or adolescent vaccines (0.6-0.9).
• Standardized policies and delivery mechanisms were more common for influenza vaccines.
• Barriers included communication issues, system inefficiencies, and discomfort with inpatient immunization.

Conclusions:

• Current hospital infrastructure significantly favors influenza vaccine delivery over other crucial pediatric vaccines.
• This disparity creates missed opportunities for essential inpatient immunizations.
• Improving systems is vital to ensure comprehensive vaccination for hospitalized children.
