The median number of days between hospital admission and mortality in those patients who died while not in hospital was 145 (interquartile range 39-215). Hospital-acquired pneumonia was more common in those patients who died after hospital discharge in comparison to patients who survived after 1-year follow-up, indicating a potential marker of poor prognosis. In-hospital mortality rate was 34% ( I n i = 1102); 1% of patients ( I n i = 28) died after hospital discharge (Fig. The main causes of death after hospital discharge were out-of-hospital cardiac arrest (10 patients, 37%); infectious diseases (six patients, 21%); and respiratory failure (six patients, 21%) (eTable3).
