Aim: Effective management of unstable patients in the emergency department during the golden hours significantly reduces mortality and morbidity. The world population is getting older and emergency room crowding is increasing. The aim of the study was to analyze the demographic characteristics, initial laboratory values and results of the patients through a retrospective analysis of non-traumatic patients who were admitted to the intensive care unit from the emergency department.

Materials and Methods: In the study, 1067 patients were included. Blood glucose, phosphorus, platelet, MPW, PDW values and demographic data were taken during the first examinations upon admission to the emergency department. Diagnoses were divided into six groups: pulmonary, internal diseases, cardiac, neurological, poisonings and infections. Outcomes were analyzed.

Results: The mean age of 1067 patients who met the criteria in the study was 69.16±15.61 years and 51.2% were male. Considering the reasons for hospitalization from the emergency service to the Intensive Care; the most frequent hospitalizations were pulmonary with 31.0% (n=337), neurological with 22.1% (n=240) and cardiac with 20.9%. Cut-off point for blood phosphorus levels ≥ 4.15 mg/dL, sensitivity 47.0% specificity 73.0% area under the ROC curve ± standard error (AUC ± SE) = 0.62 ± in patients hospitalized from the Emergency Department to the Intensive Care Unit and nonsurvivor 0.020 (p < 0.001).

Conclusion: Although the study has limitations, it was assumed that the phosphorus level pathologies of critically ill patients at the time of their first admission to the emergency department would negatively affect mortality. To clarify this issue, a large retrospective observational study is needed to determine whether patients with episodes of hypo-hyperphosphatemia have increased morbidity or mortality compared to patients with normal phosphate values. It can be predicted that phosphorus may be an important parameter in mortality scoring in emergency departments in the future.
