Conventional and computerized antepartum telecardiotocography. Experienced and inexperienced observers versus computerized analysis.
The study assessed the agreement in cardiotocogram interpretation between the 2CTG computerized system and experienced and inexperienced observers involved in a telecardiotocography project called 'TOCOMAT'. Both observers and computer analyzed FHR baseline, FHR variability, and number of large accelerations and of decelerations. The k coefficient was calculated for the statistical analysis. The interobserver agreement about the evaluation of the FHR baseline and of the large accelerations was good; it was poor about the assessment of the FHR variability and the decelerations. Similar results were obtained for the agreement among observers and computer. The use of a computerized system provides exact values for most CTG parameters; the experts, however, should rely both on clinical features and on the computerized interpretation, to make decisions about management.
