In the nurses' review, only 78 (87.6%) of the 89 AE patient charts were identified as having one or more triggers (table 3).
The sensitivity of the Canadian Association of Paediatric Health Centres Trigger Tool was 0.88 (95% CI 0.79 to 0.94) and the specificity 0.44 (95% CI 0.39 to 0.48).
Further review of the 11 (12.4%) AE charts designated by the nurses as trigger-negative revealed that the trigger: ‘Other: Any other undesirable outcomes not covered above’ could have been applied to nine charts.
