ICD-10-CA = International Statistical Classification of Diseases and Related Health Problems, 10th Revision, enhanced Canadian version; ICISS = ICD-10-CA– derived Injury Severity Score; SD = standard deviation; PYLL = potential years of life lost.
↵* We computed the mean and SD for each domain using the fatality rate, median 1 – ICISS, median cost per hospital stay and median PYLL for each mechanism.
