*Previous hospital admission: Within 90 days. P value between hospital 1 (public) and 2 (private), Pearson chi-square test was used to compare (2 qualitative variables) and student t-test was used to compare (1 quantitative variable and 1 qualitative variable), Fisher's Exact Test was used when cell counts of less than 5 comprise 25% or more.
SD: Standard Deviation; ICU: Intensive Care Unit; GSC: Glasgow Coma; SOFA: Sequential Organ Failure Assessment; APACHE II: Acute Physiology and Chronic Health Evaluation; COPD: Chronic Obstructive Pulmonary Disease.
