Evaluating the potential for opportunistic vaccination in a Northern Territory hospital

Area of Science:

• Pediatric Public Health
• Infectious Disease Prevention
• Healthcare Quality Improvement

Background:

• Hospitals present opportunities for childhood vaccination, yet coverage remains suboptimal.
• Missed vaccination opportunities are common, particularly in pediatric wards and emergency departments.
• Effective interventions are needed to improve vaccination coverage in inpatient settings.

Purpose of the Study:

• To assess the effectiveness of a simple intervention in improving opportunistic vaccination for children in hospitals.
• To evaluate changes in vaccination status documentation following staff education and prompt implementation.
• To identify barriers and facilitators for opportunistic vaccination in pediatric inpatient and emergency settings.

Main Methods:

• A pre- and post-intervention study design was employed, reviewing hospital records of children under 7 years.
• The intervention involved staff education and the introduction of prompts to record vaccination status.
• Data were collected from pediatric wards (PW) and the emergency department (ED) over 4 weeks before and after the intervention.

Main Results:

• Documentation of vaccination status significantly improved in both PW (63% to 90%) and ED (24% to 46%).
• Adequacy of recorded vaccination details also increased, particularly in PW (51% to 77%).
• Opportunistic vaccination rates showed a marginal increase (0% to 6%), with most occurring in PW; no significant improvement was observed in the ED.

Conclusions:

• While simple interventions can enhance vaccination status documentation, they are insufficient to improve opportunistic vaccination rates alone, especially in the ED.
• Numerous missed opportunities for vaccination exist in hospital settings, highlighting the need for multifaceted strategies.
• Improving documentation is a necessary but not sufficient step towards increasing childhood vaccination coverage in hospitals.
