Association between hospital admission either directly or via the emergency department, and readmission rates at 30 days in older adults in two rural hospitals: a retrospective cohort study.

Introduction: Older patients are frequently re-admitted to the hospital after attending the emergency department (ED). We investigated whether direct admission to the hospital was associated with a lower risk of readmission at 30 days compared to admission via the ED, in patients aged ≥ 75 years.

Methods: Retrospective multicenter cohort study from 01/01/2018 to 31/12/2019, including patients aged ≥ 75 years from two hospitals.
