*Only factors with a significant association at 0.1 in the bivariate model were entered into the multivariate model (n=247). Stepwise variable selection with significance level for entry into the model at 0.2 and with significance level for staying in the model at 0.05 was used. Thus, variables not appearing in the multivariate model do not fulfill these selection criteria.
D30, 30 days post-discharge; ICU, intensive care unit.
