  1. aTotal sample n = 238, n = 6 patients were lost (no contact information or consult), n = 45 did not complete 1-month follow-up. bTotal poor outcome sample n = 78, poor outcome refers to mortality or institutionalization after discharge (permanent care units), with no significant difference between these. cNo significant difference in mortality between while in EDICUM or after discharge. Charlson score Charlson comorbidity index combined condition score; CI confidence interval (95% confidence interval for the odds ratio); Coeff.coefficient expressed in logits; IQR interquartile range; LOS length of stay; SE standard error; SIRS systemic inflammatory response syndrome criteria.
