External validation of the "simplified hospital" scale as a predictor of 30-day readmission after hospitalisation in osi araba medical services.

Background: A readmission is defined as a new admission to hospital for at least one night in the 30 days following a discharge. Some are caused by events unrelated to the reason for the initial admission (unavoidable) and others caused by the same pathology (related). Different predictive models allow the identification of patients at higher risk of readmission.
