The Effect of Imputation of Pao2/Fio2 From Spo2/Fio2 on the Performance of the Pediatric Index of Mortality 3*

Conclusions: Imputation of the Pao2/Fio2 ratio in cases where arterial sampling was not performed resulted in a large reduction in the rate of missing data if all values of Spo2 were included. The imputation technique improved the discrimination of Pediatric Index of Mortality 3; however, the magnitude of the increment in overall model performance was small. A possible benefit of the approach is reducing the potential for bias resulting from variation in practice for invasive monitoring of oxygenation.
