Table 3 Accuracy and inter-rater reliability

From: The design and implementation of an obstetric triage system for unscheduled pregnancy related attendances: a mixed methods evaluation

Measure Percentage of agreement ICC (95% CI) Unweighted IRR (95% CI) c
Green 98.33% a 0.94 (0.93–1.0)
Yellow 68.33% 0.50 (0.15–0.99)b 0.70 (0.67–0.85)
Orange 96.67% a 0.83 (0.82–0.88)
Red 100% a 0.97 (0.96–1.00)
Overall 90.83% 0.961 (0.91–0.99) 0.85 (.85–.89)
  1. aunable to compute ICC due to low variance – scores are to highly consistent
  2. bNumber should be interpreted with caution due to low variance and large CIs
  3. cLight Kappa statistic used to compute unweighted IRR
  4. dBootstrap – t utilised to adjust confidence intervals [1]
