Results: The average length of stay from reception to the physician's response was 49.00 minutes, decision for admission was 884.29 minutes, and the average length of stay was 1056.62minutes. According to patients' levels of severity and the types of admission and discharge, the length of stay from physician's response, from decision for admission, and total length of stay were significantly different. Logistic regression showed the length of stay for physician's response, stay for decision of admission were the significant predictors for the delayed stay. As the stay for the physician response were delayed one minute, the possibility of the delayed stay in the emergency medical center is 1.36 times higher. As the stay for decision of admission is delayed one minute, the possibility of the delayed stay in the emergency medical center is 1.16 times higher. The most . frequent reason for the delayed stay was the shortage of hospital rooms (11.8%). Conclusion: The results showed the length of stay from the physician's response, from the decision for admission and total length of stay in a regional emergency medical center were considerably delayed. The predictable factors for the total length of stay were the stay from the physician's response and from the decision for admission.
