Electronic Alerts Improve Immunization Rates in Two-month-old Premature Infants Hospitalized in the Neonatal...

Area of Science:

• Neonatal care
• Pediatric immunization
• Health informatics

Background:

• Infants in neonatal intensive care units (NICUs) often face delayed immunizations.
• Ensuring timely vaccination is crucial for protecting vulnerable infants from preventable diseases.

Purpose of the Study:

• To evaluate the effectiveness of an electronic medical record alert in improving 2-month immunization rates for hospitalized NICU infants.
• To assess the impact of the alert on vaccine ordering and administration timeliness.

Main Methods:

• Retrospective chart review of 261 infants hospitalized in the NICU with birth weights <2 kg and continued hospitalization beyond 58 days.
• Analysis of immunization data before and after the implementation of an electronic alert (instituted in 2011) between days 56-67 of hospitalization.
• Tracking of order and administration dates for 2-month vaccine components.

Main Results:

• The electronic alert significantly decreased the timing of vaccine orders (day 67 to 61) and administration (day 71 to 64).
• Missing vaccine orders and administrations decreased substantially post-alert (orders: 14% to 3%; administrations: 21% to 4%).
• Rates of fully immunized infants by 90 days or discharge increased dramatically from 71% to 94%.

Conclusions:

• Implementing an electronic medical record alert is an effective strategy to improve infant immunization rates in the NICU.
• The alert system enhanced timely vaccine delivery and increased the proportion of infants meeting immunization milestones.
• This intervention demonstrates a significant positive impact on public health goals within a critical care setting.
