PP122 The Feasibility Assessment For Domestic Introduction Of Newborn Pulse Oximetry Screening For Critical Congenital Heart Disease

Introduction

Critical congenital heart disease (CCHD) refers to a group of heart defects that cause serious, life-threatening symptoms in the neonatal period and requires timely surgical or catheter interventions. We reviewed evidence for incorporating a mandatory neonatal CCHD screening test as a national public health project for all neonates born in Korea by analyzing the validity and cost-effectiveness of neonatal CCHD screening using pulse oximetry in Korea.

Methods

We performed a rapid literature review to establish models for the diagnostic accuracy and economic evaluation of pulse oximetry. Also, we analyzed the prevalence, mortality, and medical expenditure for different types of CCHD using the national health insurance (NHI) data. We analyzed the cost-effectiveness of pulse oximetry by comparing the group of neonates who received a combination of a physical examination and pulse oximetry, and group of neonates who only received a physical examination. For the cost-effectiveness analysis for the CCHD screening test in this study, we used a duration of one year, diagnostic accuracy as the clinical endpoint, and Life Year Gain (LYG) as the effectiveness indicator.

Results

We used recent systematic review he pooled sensitivity can be enhanced from 76.5 percent (pulse oximetry alone) to 92 percent (combined with physical examination). We used a total of 2,334 neonates with CCHD data for the economic model. Our analysis revealed that adding pulse oximetry to the routine neonatal physical examination leads to 2.34 of LYG and a cost difference of USD1,080,602, showing a ICER of KRW610,063,240 (USD461,857)/LYG.

Conclusions

Considering the benefit of LYG and cost of reducing the complications and after effects of newborns with CCHD who survived early diagnosis, it is considered to be worthwhile in Korea for a mandatory screening test.
