abstract: BACKGROUND
  The readmission in the early period (RAEP) is defined as the admission of a patient to emergency department (ED) for the second time within 72 hours after discharge from the ED.
  
  
  OBJECTIVE
  The aim of this study was to determine the disease, patient, doctor, and system related causes of RAEP.
  
  
  METHODS

  METHODS
  This study is a two-stage study that was conducted at Department of Emergency, Gazi University Faculty of Medicine. The causes of RAEP were defined as disease, patient, doctor, and system related causes.
  
  
  RESULTS
  A total of 46,800 adult patients admitted to ED during the study period and 779 (1.66%) patients required RAEP. After the exclusion criteria, 429 of these patients were included the study. The most common reasons for RAEP were renal colic in 46 (10.7%) patients. It was detected that 60.4% of the causes of RAEP were related to disease, 20.0% were related to the doctor, 12.1% were related to the patient, and 7.5% were related to the hospital management system.
