There were 277 patients who had not been admitted to an ICU; at 6 months, 268 (97%) had died, 8 (3%) were dependent (GOSE 2\u20134), and 1 (0.4%) was functionally independent (GOSE 5\u20138). There were 263 patients who had been admitted to an ICU; at 6 months, 188 (73%) had died, 39 (15%) were dependent, and 32 (12%) were functionally independent. These proportions did not change over longer follow-up.
