    Polyembolokoilamania in the Emergency Department Polyembolokoilamania is a rare but serious medical condition that involves the presence of multiple foreign bodies in the patient's body [1]. This condition can be challenging to diagnose and manage in the emergency department. In this chapter, we will discuss the presentation, diagnosis, and management of polyembolokoilamania in the emergency department.

    Objective: To assess whether prolonged length of stay in the emergency department was associated with risk of death. Methods: We analysed data from 165,183 arrivals at St. Olav’s University Hospital’s emergency department from 2011 to 2018, using an instrumental variable method. As instruments for prolonged length of emergency department stay, we used indicators measured before arrival of the patient. These indicators were used to study the association between prolonged length of emergency department stay and risk of death, being discharged from the emergency department and length of hospitalisation for those who were hospitalised. Results: Mean length of stay in the emergency department was 2.9 hours, and 30-day risk of death was 3.4%. Per hour prolonged length of stay in the emergency department, the overall change in risk of death was close to zero, with a narrow 95% confidence interval of −0.5 to 0.7 percentage points. Prolonged emergency department stay was associated with a higher probability of being discharged from the emergency department without admission to the hospital. We found no substantial differences in length of hospitalisation for patients who were admitted. Conclusion: In this study, prolonged emergency department stay was not associated with increased risk of death.
    Emergency Department overcrowding with admitted inpatients is a common international occurrence. We undertook a retrospective review to compare patient admission rates from patients presenting to our Emergency Department with the level of overcrowding with admitted inpatients on that particular day in the Emergency Department. Over the 2-year study period there was no change in the rate or absolute number of admissions per day compared with the level of inpatient overcrowding.

    In the Boarders in the Emergency Department (BED) study the impact of overcrowding due to boarders on patients' mortality and the likelihood of being diagnosed with methicillin resistant Staphylococcus aureus (MRSA) during admission was examined. With regard to efficiency, the impact of overcrowding on the time to first medical assessment for admitted patients, the number of patients leaving without being seen, and the rate of admission as a percentage of total emergency department attendances was explored.The retrospective cohort analysis study of all emergency department admissions was performed using information accessed via the Diver Solution. The software integrated information from several databases.The average number of patients awaiting hospital admission in the emergency department at 09:00 was 20.4 (range 0-45). The average duration of stay in the emergency department following the decision to admit was 16.1 h (range 0-161 h). The number who did not wait (DNW) to be seen was strongly correlated with the time waiting for medical assessment, which in turn was correlated with the total number of attendances to the emergency department (p<0.001). The elderly waited longer for admission and had the highest mortality and the highest chance of being diagnosed with MRSA during their overall admission.It is wrong for patients who are sick enough to require admission to hospital to be kept in the emergency department, and the entire health system must respond to their plight.
