There is a worldwide shortage of the specialized intensive care beds needed to meet the demand of eligible patientsand this is one of the principal factors limiting intensive care unit (ICU) admis¬sions. Methodology: To assess the frequency, common causes and risk factors of patients readmitted in ICU within 72 (after transferred of ICU), during the study period, 242 patients were transferred from ICU, 25 (10.3%) patients were readmitted. (patients who were readmitted to the ICU with diagnosis) Renal failure during the initial ICU stay was higher compared with among patients who were readmitted to the ICU. Finding: The reasons for admission to ICU was significant difference with readmission. Time transferred from the ICU was significant difference with readmission. 69% in the evening, 23.6% in the morning, 7.4% in the night. Conclusions: Many risk factors for early ICU readmission were identified in this study including type of disorder at the time of admission to ICU and the time of transfer from the ICU. Studies are required to identify other factors and to determine whether interventions may reduce ICU readmission.
