Abstract

Purpose
: Many inborn errors of metabolism can be completely cured with early detection and early treatment. This is why neonatal screening on inborn errors of metabolism is implemented worldwide. In this study, a cost-benefit analysis was performed on the neonatal screening of phenylketonuria and congenital hypothyroidism in Korea.
Methods
: This study included 2,908,231 neonates who took the neonatal screening on phenylketonuria and congenital hypothyroidism in Korea from January 1991 to December 2003. From those neonates, the incidence rates of phenylketonuria and congenital hypothyroidism were measured. Furthermore, based on 495,000 babies born in 2002, were calculated and compared the total costs in case when neonatal screening on phenylketonuria and congenital hypothyroidism is implemented, and when not.
Results
: If the neonatal screening on phenylketonuria and congenital hypothyroidism is implemented, benefits far exceed costs at a ratio of 1.77 : 1 in phenylketonuria, and 11.11 : 1 in congenital hypothyroidism. In terms of wons, the present neonatal screening on phenylketonuria and congenital hypothyroidism will gain us more than 29 billion wons every year.
Conclusion
: This study only concerns the monetary aspects of the neonatal screening. Therefore, the benefits of the neonatal screening is underestimated by ignoring precious but not measurable values such as quality of life. However, the present neonatal screening on phenylketonuria and congenital hypothyroidism is found to be beneficial and should continue for the good of the nation as well as that of the patients.
