The study will be conducted between 15.12.2020 and 15.03.2021. Patients over the age of 18 who applied to the emergency department with any complaint and whose blood glucose level> 300 mg / dl in the examinations (as the finger tip and / or blood biochemistry examination parameter) performed in case of clinical necessity will be included in the study. Patients or their relatives (for patients who are unable to give consent) will be asked to read and sign the informed consent form if they accept it. Patients' age, gender, history, whether they are diagnosed with diabetes, medications used, vital signs, complaints of admission to the emergency room, hospitalization and definitive diagnosis will be recorded. The study form for the followed-up patients will be added to each patient's file and filled in by the physicians in the patient's follow-up.~The following parameters will be included in the work form;~Age of the patient~Gender~Biography~Presence of diabetes diagnosis, drugs used, if any~Other medications~The complaint of applying to the emergency room~Whether treatment for hyperglycemia is applied in the emergency department, what treatment is applied~How much IV fluid and / or insulin therapy is applied~Duration of stay in the emergency department~Results of routine blood tests~Weight~The trend of blood glucose levels in patients treated for hyperglycemia~Presence of acute complications due to hyperglycemia~Application and discharge BG levels~Whether there are classical symptoms of DM before admission to the emergency department~Whether hypoglycemia develops or not~Was medication prescribed for DM at the time of discharge?~Whether he was hospitalized or not. Patients will be called 30 days after leaving the emergency room (ER). Within this period, whether they applied to the emergency service again, if they did, the application complaint, the diagnosis of ER discharge, and the treatment method used will be questioned.
The main purpose of this study is how to manage hyperglycemic patients in emergency departments, to determine the conditions that require blood glucose regulation and to examine the prognosis of the patients in the next 30 days, depending on the regulation method.
