Objective Acute vestibular syndrome (AVS) is a common symptom experienced by emergency department (ED) patients. Differentiating a peripheral from central etiology poses a challenge, and clinical practice lacks a uniform diagnostic approach. This study aims to provide insight on incidence and diagnostics in ED patients presenting with AVS in the Netherlands.
Methods This was a multicenter retrospective cohort study of ED patients presenting with AVS in one of two hospitals during a 3-year period. The primary endpoints were incidence, diagnostics, and diagnosis at ED presentation versus follow-up. The secondary endpoint was type of therapy.
Results Among the 500 AVS cases included, the annual incidence was 0.1%. Eighty-five ED patients (17.0%) were diagnosed with stroke, 285 (57.0%) did not experience stroke, and 130 (26.0%) exhibited an unsure etiology. At follow-up, diagnosis was revised in 145 patients (29.0%), with stroke missed in 29 (5.8%). A triad of clinical tests (head impulse test, observation of nystagmus, test of skew; HINTS) was completed for 106 patients (21.2%), computed tomography (CT) scans were collected in 342 patients (68.4%), and magnetic resonance imaging scans were collected for 153 patients (30.6%). Antiplatelet therapy was prescribed in 135 cases. In 69% of these, the initial diagnosis was revised to no stroke. Among eight patients who received thrombolysis, the initial diagnosis was revised for three. Of those patients in whom stroke was initially not identified, 23 (79%) received suboptimal treatment in lieu of antiplatelet therapy.
Conclusion The annual incidence of AVS in this Dutch ED cohort is 0.1%. ED diagnosis is often uncertain, with one-third of diagnoses later revised. This study substantiates that clinical practice lacks a uniform diagnostic pathway, with an overuse of CT imaging and underuse of HINTS. Further research on an optimal diagnostic approach is warranted to improve treatment of AVS.

Objective A common emergency department (ED) patient care outcome metric is 72-hour ED return visits (EDRVs). Risks predictive of EDRV vary in different studies. However, risk differences associated with related versus unrelated EDRV and subsequent EDRV disposition deviations (EDRVDD) are rarely addressed. We aim to compare the potential risk patterns predictive of related and unrelated EDRV and further determine those potential risks predictive of EDRVDD.
Methods We conducted a large retrospective observational study from September 1, 2015 through June 30, 2016. ED Patient demographic characteristics and clinical metrics were compared among patients of 1) related; 2) unrelated; and 3) no EDRVs. EDRVDD was defined as obvious disposition differences between initial ED visit and return visits. A multivariate multinomial logistic regression was performed to determine the independent risks predictive of EDRV and EDRVDD after adjusting for all confounders.
Results A total of 63,990 patients were enrolled; 4.65% were considered related EDRV, and 1.80% were unrelated. The top risks predictive of EDRV were homeless, patient left without being seen, eloped, or left against medical advice. The top risks predictive of EDRVDD were geriatric and whether patients had primary care physicians regardless as to whether patient returns were related or unrelated to their initial ED visits.
Conclusion Over 6% of patients experienced ED return visits within 72 hours. Though risks predicting such revisits were multifactorial, similar risks were identified not only for ED return visits, but also for return ED visit disposition deviations.

Objective To analyze the trends in demographics and outcomes of patients presenting with traumatic brain injury by performing a retrospective database review of the Illinois Department of Public Health (IDPH) Trauma Registry.
Methods We utilized the IDPH Trauma Registry to retrieve data on patients treated for traumatic brain injuries at our large, tertiary care hospital from 2004 to 2012, inclusive. From this data, logistic regression models were used to analyze and compare basic demographics such as age, sex, and clinical outcome.
Results Three thousand and thirty-nine patients were analyzed with a mean age of 43 (standard deviation, 24) and a median age of 41 (interquartile range, 23 to 60). Over the study period, patients’ age increased steadily from 32 to 49 years. The percentage of female patients increased, from 16.4% to 27.5% over the last 4 years. Overall mortality was greater for males than females (22.1% vs. 17.3%; odds ratio [OR], 1.36; 95% confidence interval [CI], 1.10 to 1.68). Mortality decreased over the period (OR, 0.88; 95% CI, 0.85 to 0.91), with a greater decrease in females (OR, 0.84; 95% CI, 0.78 to 0.90) than in males (OR, 0.90; 95% CI, 0.86 to 0.94).
Conclusion Although the age of patients presenting with traumatic brain injury is increasing substantially, the data suggests that overall mortality appears to be decreasing, and this decrease appears to be greater in females than in males. These changes in trends found in the IDPH Trauma Registry supports the importance for further analysis of other reliable public datasets to identify areas of future study.

Objective We aimed to determine the incidence, processes of care, and outcomes in out-of-hospital cardiac arrests (OHCA) in Ansan, South Korea. Methods From the Ansan Fire Department’s (1-1-9 emergency call number) Emergency Medical Services (EMS) database, we obtained a list of adult cardiac arrest cases occurring between January 2008 and December 2011. We excluded cases with obvious non-cardiac causes, such as trauma, drowning, hanging, and asphyxia. We matched the EMS data with in-hospital care and outcome data. We analyzed basic demographic variables (age and gender), the time and place of incidence, witnesses, bystander cardiopulmonary resuscitation (CPR), major time variables, CPR instructions during transport, initial cardiac rhythm at the scene, and automated defibrillator use.
Results The overall incidence of OHCA in Ansan was 33.1/100,000 persons per year. Out of 778 adult OHCAs in our study population, bystander CPR was provided in 103 cases (13.2%). Of the 517 OHCAs whose initial rhythms were confirmed, 85 (16.4%) showed shockable rhythms, but only 23 (27.1%) received defibrillation at the scene or during transportation. Of the 106 patients whose spontaneous circulation returned at the hospital, only 6 (5.7%) received mild therapeutic hypothermia. During the study period, 31 patients (4%) survived to discharge from hospitals, and 6 of these discharged patients (19.4%) showed favorable neurologic outcomes. Conclusion While the survival rate from OHCA in Ansan is very low, this study provides basic information needed to create improvements. Our analysis suggests that multiple variables contribute to the low OHCA survival rate. Several of these variables are modifiable; addressing them is a clear first step toward strengthening the chain of survival from OCHA in Ansan.
