Intrapartum cardiotocogram monitoring between obstetricians and computer analysis

Abstract Purpose: To investigate the accuracy of computer analysis and its features to be used as a fu fetal heart rate (FHR) interpretation method in clinical settings.Methods: The Trium CTG Online® was used as the computer analysis software. Twenty six cases of intrapartum FHR tracings (total time, 6900 min) were randomly selected from third trimester pregnancies. Three obstetricians blinded to the patients’ clinical information traced the decelerations, variability, and baseline cardiotocogram (CTG) data. Three obstetrician observer individually interpreted the data, and only the waveforms they interpreted were adopted. The agreement between the deceleration and baseline, variability, and level of five-tier system was estimated. Weighted kappa (κ) statistics was used to assess reliability.Results: Based on the observers and Trium’s classification, κ was 0.78 and strength of agreement level was substantial. The obstetricians and Trium mostly agreed on the variability and baseline data. However, κ of eac...
