Inter‐observer variation in assessment of 845 labour admission tests: comparison between midwives and obstetricians in the clinical setting and two experts
Objective To assess the inter‐observer agreement in assessment of the labour admission test between midwives and obstetricians in the clinical setting and two experts in the non‐clinical setting, the inter‐observer agreement between two experts in the non‐clinical setting and to what degree fetal di...

The traces were assessed as normal, equivocal or ominous. Weighted kappa (κw), proportion of agreement (Pa) and predictive values were calculated. Main outcome measures Weighted kappa, proportion of agreement, sensitivity, positive predictive value and likelihood ratios. Results Inter‐observer agreement between Expert 1 and Expert 2: κw 0.38 (CI 0.31–0.46), Pa for reactive labour admission test 0.86 (CI 0.83–0.88) and Pa for equivocal/ominous test 0.33 (CI 0.26–0.40). Agreement between Expert 1 and midwives/obstetricians: κw 0.25 (CI 0.15–0.36), Pa for reactive labour admission test 0.89 (CI 0.87–0.91) and Pa for equivocal/ominous labour admission test 0.18 (CI 0.11–0.25). Agreement between Expert 2 and midwives/obstetricians: κw 0.28 (CI 0.20–0.37), Pa for reactive labour admission test 0.85 (CI 0.82–0.88) and Pa for equivocal/ominous test 0.20 (CI 0.14–0.26). Totally 5.9% of the newborns had fetal distress. At cutoff equivocal test, sensitivity was 0.22 and 0.31 in the two observers. Positive predictive values were 0.13 and 0.11.
