^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.
