Interobserver agreement among experienced obstetricians for classifying CTG and making clinical decisions using STAN guidelines is only moderate.
Ojala et al. (2008) conducted an observational in Singleton, vertex, term pregnancies (n=200). Intrapartum automated fetal electrocardiogram ST interval analysis (STAN) was evaluated on Interobserver agreement evaluated by weighted kappa values and proportion of agreement (kappa(w) 0.47-0.60). Interobserver agreement among experienced obstetricians using STAN guidelines for CTG classification and clinical decision-making was moderate (weighted kappa 0.47-0.60, agreement 56-86%).
