Time to reconsider : Have the 2015 FIGO and 2017 Swedish intrapartum cardiotocogram classifications led us from Charybdis to Scylla?
(2021) In Acta Obstetricia et Gynecologica Scandinavica 100(9). p.1549-1556- Abstract
In 2015, FIGO revised the 1987 intrapartum cardiotocography (CTG) classification (FIGO1987). A less radical FIGO2015 version was introduced in Sweden 2017 (SWE2017). Now, post hoc simulation studies show that FIGO2015 and SWE2017 are less reliable than (a modified) FIGO1987. FIGO2015 shows significantly better interobserver agreement for normal CTG traces than FIGO1987, but significantly worse for pathological traces. Agreements between templates are moderate to good, but different classifications of mainly variable decelerations and tachycardia cause significant heterogeneities. FIGO2015 shows insufficient sensitivity to identify fetal acidemia compared with FIGO1987. In connection with fetal electrocardiogram ST analysis, one study... (More)

FIGO2015 shows insufficient sensitivity to identify fetal acidemia compared with FIGO1987. In connection with fetal electrocardiogram ST analysis, one study showed no template was superior in identifying fetal acidemia, but in a series of only academia, FIGO1987 had significantly higher sensitivity than FIGO2015 (73% vs. 43%) and set of an alarm for fetal acidemia considerably earlier. With SWE2017, operative interventions declined significantly in Sweden but several adverse neonatal outcomes increased significantly. It remains to investigate the development with FIGO2015.
