The Emergency Department (ED) overcrowding is an ongoing problem all over the world. The scoring systems are available for the detection of this problem. This study aims to test the applicability of the National Emergency Department Overcrowding Study (NEDOCS) scoring system, one of the scoring systems that evaluate the ED overcrowding. In this prospective observational study, the survey was applied on on-duty doctors, nurses, paramedics, intern doctors, and ward persons working in a University Adult Emergency Department and agreed to participate in the study, between certain hours during the day and the NEDOCS score was calculated simultaneously. The demographic characteristics of the on-duty staff, overcrowding of ED, and the number of the on-duty staff members were recorded in the questionnaires. During the study, 153 measurements were performed, and 3221 questionnaires were filled. The NEDOCS mean score was determined as 101.59 and the most reached result was “extremely busy but not overcrowded” (32%). The ED was rated mostly as “busy” (33.7%) by the on-duty staff. A significant difference was found between ED overcrowding and NEDOCS score. There is a significant difference between ED overcrowding and on-duty emergency nurse and intern doctor count. The NEDOCS score is not suitable for evaluating ED overcrowding. Accurate determination of the ED overcrowding is very important to avoid the negative consequences of the ED overcrowding. Increasing emergency nurse and intern doctor count will decrease ED overcrowding. Also, there is an urgent need to constitute local hospitals and also public health policies to satisfy the increasingly ED's presentations.

Objectives: Abdominal pain occupies most of the emergency department admissions. This entity leads to research various markers for the early detection of causes in patients presenting with abdominal pain. There is limited data about collaborations between lactate levels and vital signs at admission in abdominal pain. Materials and Methods: Patients aged 18 years and older, who had presented with abdominal pain to the Emergency Department, in total 102 patients, were included to the study. The patients’ demographics, vital signs, abdominal physical examination findings, diagnosis and outcomes of patients were recorded. The 1 ml venous blood samples were collected by blood gase injectors from the patients and lactate levels were analyzed. Results: Female patients’ percentile was 68,6% and mean age was 39 years old. The systolic blood pressure levels were normal in 45 patients, low in 26% patients and high in 29% patients. The seventy-six of the patients had normal pulse rate and 26 of them were tachycardic. Most common diagnosis was non-specific abdominal pain (37,25%) and the least common was ovarian torsion/intracystic hemorrhage (0,98%) and obstruction due to hernia (0,98%). There was no statistically significant relation between lactate level and pulse rate (p=0,637), systolic blood pressure (p=0,052), diastolic blood pressure (p=0,095), respiratory rate (p=0,527), body temperature (p=0,040) and oxygen saturation (p=0,905). Similarly, no significant association occurred between lactate levels and diagnosis and outcomes. Conclusion: Further studies including more patients groups have to be done in order to attain more reliable data about this topic.
