Implementation and analysis of a pilot in-hospital newborn screening program for glucose-6-phosphate dehydrogenase...

Area of Science:

• Neonatal Medicine
• Medical Genetics
• Public Health Screening

Background:

• Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an inherited condition that can lead to hemolytic anemia.
• Hyperbilirubinemia is a common complication in newborns, and G6PD deficiency is a known risk factor.
• Effective screening programs are crucial for early identification and management of at-risk infants.

Purpose of the Study:

• To evaluate the effectiveness of a targeted newborn screening program for G6PD deficiency.
• To compare clinical outcomes, specifically hyperbilirubinemia, between G6PD-deficient and G6PD-normal newborns.
• To assess the feasibility of rapid turnaround times for G6PD screening in a hospital setting.

Main Methods:

• Retrospective chart review of 1578 male newborns.
• Targeted screening for G6PD deficiency in a study group of 1095 newborns.
• Statistical analysis using chi-squared test and unpaired t-test for comparisons.

Main Results:

• 11.1% of screened newborns were diagnosed with G6PD deficiency.
• Screening results were available within 48 hours for 97.8% of infants.
• G6PD-deficient infants had significantly higher total bilirubin levels and were more likely to receive phototherapy.
• 47% of newborns rehospitalized for hyperbilirubinemia were found to have G6PD deficiency.

Conclusions:

• In-hospital newborn screening for G6PD deficiency with rapid results is achievable.
• G6PD deficiency is identified as a significant risk factor for developing hyperbilirubinemia in American newborns.
• US healthcare centers serving populations with a high prevalence of G6PD deficiency can implement similar screening protocols to identify at-risk infants.
