Contribution of tempo-related and non-tempo-related incidents to the five main classes of adverse events

Nature of adverse events	Series of 249 files of non-tempo-related incidents for GPs	Series of 623 files of tempo-related incidents (at least one tempo concerned with the issue)
Missed or delayed diagnosis	7.2% (18)	25.6% (160)
Adverse drug events	21.7% (54)	24.1% (150)
Poor strategy of care, inadequate treatment, surveillance	20.1% (50)	20.7% (129)
Ethics, conflict management, and miscellaneous	39.8% (99)	17.2% (107)
Falls/device and care-induced traumas	11.2% (28)	12.4% (77)
Total	100% (249)	100% (623)

Percentages are calculated separately for the series of non-tempo-related problems (N=249) and for tempo-related problems (N=623). The total of 1046 files also included 174 claims that had no data or no independent expert review and were excluded from the review (raw data are in brackets).
