Validation of predictive factors for hospital admission in elderly patients transported by emergency medical services: a retrospective observational study

This is the first study to identify clinical and situational factors associated with hospital admission among older patients receiving home call medical services at home or in the NH who were transported by EMS. Among these patients, hospital admission was associated with suspected infection; cardiovascular, cerebrovascular, and digestive diseases; oxygen therapy in the ED; and reduced consciousness. These findings may help guide triage and decision-making in emergency care for this vulnerable population.
