CI = confidence interval; LOS = length of stay in hospital; OR = odds ratio.
↵* Admission and initial resuscitation at 1 hospital followed by transfer to another hospital for surgery. Includes cases with transfer between 2 peripheral centres.
↵† Unable to include in logistic regression model owing to collinearity with long total LOS.
