Insights
A simple reminder system and education improved vaccination rates for preterm infants, a high-risk group. This audit successfully closed the loop on previous suboptimal immunisation status.
Area of Science:
- Pediatrics
- Immunology
- Public Health
Background:
- Preterm infants face higher risks of vaccine-preventable diseases.
- A previous audit in 2007 revealed suboptimal immunisation coverage in this vulnerable population.
- Addressing these gaps is crucial for protecting infant health.
Purpose of the Study:
- To re-audit the immunisation status of preterm infants.
- To evaluate the effectiveness of interventions aimed at improving vaccine uptake.
- To complete the 'audit loop' by assessing changes since the 2007 audit.
Main Methods:
- A retrospective follow-up audit was conducted at a tertiary pediatric hospital.
- Interventions included a reminder sticker system and feedback to healthcare professionals.
- Immunisation records were obtained from the Australian Childhood Immunisation Register for infants born <32 weeks gestation.
Main Results:
- The majority of preterm infants (96%) were up-to-date with routine immunisations by 12 months.
- Receipt of the hepatitis B vaccine at 12 months increased 2.4-fold compared to the previous audit.
- Influenza vaccine uptake also improved in preterm infants with chronic lung disease.
Conclusions:
- A straightforward reminder system coupled with educational strategies significantly enhances vaccine delivery for high-risk groups like preterm infants.
- These interventions are effective in improving immunisation coverage in special populations.
- Closing the audit loop demonstrates the success of targeted quality improvement initiatives.
Aim:
Preterm infants are at increased risk of vaccine preventable diseases. An audit in 2007 identified suboptimal immunisation status of preterm infants. The aim of this study was to complete the 'audit loop', reviewing preterm infants' immunisation status at a single tertiary paediatric hospital.
Methods:
A retrospective follow-up immunisation audit was conducted at The Royal Children's Hospital, Melbourne, neonatal unit. The 'audit loop' included a preterm infants' reminder sticker and feedback of the original audit findings to Royal Children's Hospital health-care professionals. Immunisation status was determined using the Australian Childhood Immunisation Register record for all admitted preterm infants born <32 weeks gestation (July 2008-June 2009).
Results:
Conducted in March 2011, the median age of participants (n = 57) was 2.5 years (range 1.7-3.1 years). Forty-four per cent (25/57) had a history of chronic lung disease, 86% (49/57) were <1500 g and 42% (24/57) <28 weeks gestation. The majority (96% (55/57)) were up to date with routine immunisations at 12 months of age. There was a 2.4-fold increase, compared with the original audit, for receipt of the additional recommended hepatitis B vaccine at 12 months of age, as well as influenza vaccine in infants with chronic lung disease.
Conclusion:
This study showed that a simple reminder combined with education strategies can improve vaccine delivery in special risk groups such as preterm infants.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
