When tracings were stratified by pH, inter-observer category agreement was moderate for pH > 7.1 but poor for more acidemic groups. Conclusion Pattern recognition was insufficient for reliable application of the NICHD three-tier system among naive reviewers. While agreement was generally fair to ...
Interobserver agreement was assessed using the free-marginal kappa coefficient.Results Reviewers demonstrated substantial to excellent agreement on baseline rate (k = 0.97), moderate variability (k = 0.80), accelerations (k = 0.62), decelerations (k = 0.63), category (k = 0.68), and the ...
Older obstetricians (residency prior to 2004) were more likely to choose Category 3 than were newer clinicians (33% vs 21%, p=0.03). There were no differences in agreement based on other demographics including provider type (CNM vs OB) or formal FHT training. Conclusions Inter-observer ...
The intra-observer agreement ranged from substantial to perfect for the 3 examiners (kappa 0.74-1.0). There were no cases where a FHR tracing was classified as Category I by one examiner but Category III by another. Moderate inter-observer agreement was present for individual FHR parameters: ...
