Pulse ox screening helps detect duct-dependent circulation

Investigators compared the overall rate of detection of duct-dependent circulation in one region of Sweden that screened with pulse ox with other regions that used physical examination alone. The total number of infants with duct-dependent circulation was 60 in the screening region, and 100 in all the other regions combined.

The combination of neonatal physical examination plus pulse ox screening for duct-dependent heart disease had a detection rate of 82.8%, with a low false positive rate of 0.17% for pulse ox. This compares with a 62.5% detection rate for physical examination alone. Whereas undiagnosed critical heart disease was not associated with a single infant death in the region using pulse ox screening, it was responsible for five deaths in the region not using the screening. Furthermore, 92% of all babies with duct-dependent circulation were diagnosed before leaving the hospital in the screening region, a significantly higher proportion than among babies from other regions of Sweden (de-Wahl Granelli A, et al: BMJ 2009;338:3031).

Commentary

This study is similar to a Norwegian report of last year, with one important difference. In the earlier study, pulse ox was done on admission to the nursery, while here it was on the day of discharge (see #5 on the accompanying Top 10 for citation). The delay may explain why the false positive rate was lower in the current study-0.17% instead of 0.6%. This lower rate, when applied to large groups of newborns, results in many fewer echocardiograms, lower screening cost, and increased likelihood that pulse ox screening will be adopted. The authors found that referral of all cases with positive oximetry results for echos resulted in only 2.3 echos with normal cardiac findings for every true case of duct-dependent circulation.
