-
Reviewers could select more than one prevention strategy per AE. The number of preventable AEs with technical causes was too small to calculate percentages for the prevention strategy categories.
-
↵* Percentages were weighted for oversampling of deceased patients and of patients admitted to a university hospital.
-
↵† Within subgroups of AEs that have human, organisational, patient-related or other causes, respectively.
