Scope and efficiency of the newborn screening program in identifying hemoglobin S

Area of Science:

• Public Health
• Genetics
• Neonatal Care

Background:

• Brazil's National Neonatal Screening Program added hemoglobinopathies in 2001.
• Periodic assessments are vital for monitoring program implementation and goal achievement.

Purpose of the Study:

• To evaluate the scope and efficiency of Brazil's National Newborn Screening Program.
• Specifically assessing the program's effectiveness in identifying hemoglobin S.

Main Methods:

• Cross-sectional study analyzing heel prick test results (2006-2010) in Mato Grosso do Sul.
• High-performance liquid chromatography (HPLC) used for hemoglobin S identification.
• Key variables: coverage, prevalence, and timeliness of diagnosis and consultation.

Main Results:

• Mean coverage rate of 91.77% over five years.
• Prevalence of hemoglobin FAS at 1.65% and hemoglobin FS at 0.011%.
• 87.80% of diagnoses occurred within 28 days; improvements in consultation timeliness noted by 2010.

Conclusions:

• The National Neonatal Screening Program demonstrates good scope and efficiency in identifying hemoglobinopathies.
• Key recommendations include enhanced training, improved post-diagnosis care assessment, and genetic counseling for mothers.
