Résumé
Objective@#Emergency department (ED) overcrowding is a global issue that negatively impacts the clinical outcome. Through the coronavirus disease 2019 (COVID-19) pandemic era, overcrowding of ED isolated territory (isolation bed) was aggravated. This study analyzed overcrowding indices of ED isolation beds during the COVID-19 pandemic. @*Methods@#This study was a single-center, retrospective, observational study. The study analyzed 34,925 patients who visited the ED during the COVID-19 pandemic from April 2021 to August 2022. Patients who were treated in isolation beds and regular beds were compared. Among the patients using isolation beds, patients who stayed longer than 720 minutes were also classified and analyzed. @*Results@#During the analysis period, 4,479 and 34,943 patients were treated in the ED isolation bed and ED regular bed, respectively. The overcrowding indices (general ward admission rate, intensive care unit admission rate, ED-length of stay, transfer rate, mortality rate, prolonged ED stay patient ratio) of the isolation beds were significantly higher than those of the ED regular bed (P<0.05). The prolonged ED stay-patient ratio of isolation beds and regular beds was affected by the number of COVID-19 patients (regular bed, r=0.617 and P=0.01; isolation bed, r=0.525 and P=0.03). The average ED-length of stay of isolation beds was longer than that of the ED regular beds. One hundred and forty-five patients were classified as prolonged ED stay patients. Their time from the decision point to the discharge point comprised a higher rate with an average of 76.52%. @*Conclusion@#ED isolation beds are more vulnerable to infectious disease outbreaks. A proper medical policy and arrangement management system that can flexibly deal with disaster emergencies are required

Objective@#Patients presenting with fingertip skin defect injuries without exposed bone can avail of two treatment options at the emergency department (ED). This study compared outcomes between dressing and composite graft (CG) using skin stump for patients visiting the ED with fingertip skin defect injuries without exposed bone. @*Methods@#This was a single-center, retrospective, observational study. We reviewed 244 patients with fingertip skin defect injuries without exposed bone who visited the ED from September 2018 to February 2021. We compared the outcomes of the patients who were treated by CG using skin stump and those who received a dressing in the ED. @*Results@#In all, 142 patients were treated by CG using skin stump, and 102 patients were given a dressing only. In the CG group, good outcomes were obtained in 140 patients, whereas additional skin graft treatment was required for two patients with bad outcomes. In the dressing group, 81 patients had good outcomes and 21 patients had bad outcomes which required additional skin graft treatment. @*Conclusion@#Results of our study revealed that compared to traditional dressing, ED treatment for fingertip skin defects without exposed bone showed good outcomes when administered CG using skin stump. Hence, we recommend that instead of simple dressing, CG using skin stump is the preferred mode of treatment for patients presenting in the ED with fingertip skin defect injuries without exposed bone.

Objective@#We aimed to compare the multi-marker strategy (copeptin and high-sensitivity cardiac troponin I [hs-cTnI]) with serial hs-cTnI measurements to rule out acute myocardial infarction (AMI) in patients with chest pain. @*Methods@#This prospective observational study was performed in a single emergency department. To test the non-inferiority margin of 4% in terms of negative predictive value (NPV) between the multi-marker strategy (0 hour) and serial hs-cTnI measurements (0 and 2 hours), 262 participants were required. Samples for copeptin and hs-cTnI assays were collected at presentation (0 hour) and after 2 hours. The measured biomarkers were considered abnormal when hs-cTnI was >26.2 ng/L and when copeptin was >10 pmol/L. @*Results@#AMI was diagnosed in 28 patients (10.7%). The NPV of the multi-marker strategy was 100% (160/160; 95% confidence interval [CI], 97.7% to 100%), which was not inferior to that of serial hs-cTnI measurements (201/201; 100%; 95% CI, 98.2% to 100%). The sensitivity, specificity, and positive predictive value of the multi-marker strategy were 100% (95% CI, 87.7% to 100%), 68.1% (95% CI, 61.7% to 74.0%), and 27.2% (95% CI, 18.9% to 36.8%), respectively. The sensitivity, specificity, and positive predictive value of serial hs-cTnI measurements were 100% (95% CI, 87.7% to 100%), 85.5% (95% CI, 80.4% to 89.8%), and 45.2% (95% CI, 32.5% to 58.3%), respectively. @*Conclusion@#The multi-marker strategy (copeptin and hs-cTnI measurement) was not inferior to serial hs-cTnI measurements in terms of NPV for AMI diagnosis, with a sensitivity and NPV of 100%. Copeptin may help in the early rule-out of AMI in patients with chest pain.
Résumé
OBJECTIVE: This study aimed to determine whether simultaneous decreases in the serum levels of cell adhesion molecules (intracellular cell adhesion molecule-1 [ICAM-1], vascular cell adhesion molecule-1 [VCAM-1], and E-selectin) and S100 proteins within the first 24 hours after the return of spontaneous circulation were associated with good neurological outcomes in cardiac arrest survivors. METHODS: This retrospective observational study was based on prospectively collected data from a single emergency intensive care unit (ICU). Twenty-nine out-of-hospital cardiac arrest survivors who were admitted to the ICU for post-resuscitation care were enrolled. Blood samples were collected at 0 and 24 hours after ICU admission. According to the 6-month cerebral performance category (CPC) scale, the patients were divided into good (CPC 1 and 2, n=12) and poor (CPC 3 to 5, n=17) outcome groups. RESULTS: No difference was observed between the two groups in terms of the serum levels of ICAM-1, VCAM-1, E-selectin, and S100 at 0 and 24 hours. A simultaneous decrease in the serum levels of VCAM-1 and S100 as well as E-selectin and S100 was associated with good neurological outcomes. When other variables were adjusted, a simultaneous decrease in the serum levels of VCAM-1 and S100 was independently associated with good neurological outcomes (odds ratio, 9.285; 95% confidence interval, 1.073 to 80.318; P=0.043). CONCLUSION: A simultaneous decrease in the serum levels of soluble VCAM-1 and S100 within the first 24 hours after the return of spontaneous circulation was associated with a good neurological outcome in out-of-hospital cardiac arrest survivors.
