Key result
Computerized fetal heart rate analysis with interactive advice improved cardiotocogram record quality (up to 28% without signal loss) and potentially reduced recording time.

Does computerized fetal heart rate analysis improve cardiotocogram quality and interpretation in pregnant women?
Computerized fetal heart rate analysis improves cardiotocogram record quality and saves time compared to visual analysis, which was found to be unreliable.
Dawes et al. (1992) conducted an RCT in Pregnancy (n=2,869). Computerized fetal heart rate (FHR) analysis vs. Concealed computerized analysis was evaluated on Quality and duration of the cardiotocogram; quantitative measurement of FHR variation; number of stillbirths. Computerized fetal heart rate analysis with interactive advice improved cardiotocogram record quality (up to 28% without signal loss) and potentially reduced recording time.
