Effect of newborn screening for critical CHD on healthcare utilisation

New born pulse oximetry screening: A global perspective

The possibility of pulse oximetry screening (POS) for congenital heart defects was first described over 20 years ago. Since then, an accumulation of research evidence and clinical practice experience has established POS as an important test to detect critical congenital heart defects (CCHDs). POS meets the criteria for universal screening and professional bodies around the globe have recommended universal POS. Many countries have already adopted POS while several others are working towards its implementation. In low and low-middle-income countries (LLMIC), POS has the additional potential for reducing morbidity and mortality from neonatal sepsis. This review summarises the evidence for POS and looks at current global uptake and different approaches to the implementation of POS.
