Up to one-third of patients are readmitted to a different hospital although it is unclear whether the readmission site affects subsequent outcomes. For example, although most patients are readmitted to the original hospital, a substantial proportion of patients are readmitted to a different hospital (16.7–29.3%) [1–3]. Readmission to different hospitals can contribute to care fragmentation, which is concerning because the original hospital is more likely to understand the patient's needs and develop a care plan.
