Emergency department (ED) visits can be divided into urgent and non-urgent. A delay in seeking medical help, especially in urgent cases, can lead to fatal consequences, along with a higher rate of complications and morbidity. Coronavirus disease 2019 (COVID-19) pandemic spread led to restrictions and eventually quarantines. We investigated the impact of the COVID-19 spread and quarantine on ED visits rates comparing to parallel periods in preceding years (2013–2019). In addition, we compared this decrease to holidays and weekends, times in which a decrease in ED visits is seen. This was a descriptive retrospective study. Causes of ED referrals were divided into urgent and non-urgent, then into different subcategories including infectious, cardiac, etc. For the spring COVID-192020 quarantine period, a 56.3% decrease of mean ED visits per day was seen, as compared to preceding years (55.7% and 98.9% respectively). This decrease was also statistically evident when comparing the urgent and non-urgent causes separately and for all sub-categories. This pattern of decrease also showed statistical evidence of fewer ED visits during holidays for most comparisons, in which lower ED visit rates are expected. Significantly lower rates of ED visits were demonstrated during the COVID-19 quarantine period, as compared to preceding years and main holidays and weekends, a decrease that was also demonstrated for urgent life-threatening causes. Our findings can be used to inform a wide range of stakeholders, including regional planners, historians, sociologists, and international healthcare organizations. Healthcare providers should understand the reasons for this ED visit decline pattern, attempt to address patients' concerns, and increase awareness regarding alarming symptoms in urgent medical situations. • We investigated the impact of the COVID-19 spread and quarantine on emergency department (ED) visits rates. • For the COVID-19 quarantine period, a 56.3% decrease of mean ED visits per day was seen, as compared to preceding years. • This decrease was also evident when comparing the urgent and non-urgent causes separately and for all sub-categories. • Our findings can be used to inform a wide range of stakeholders, including international healthcare organizations. • Healthcare providers should understand the reasons for this ED visit decline and attempt to address patients concerns.

Background: Urinary tract infection (UTI) is frequently encountered in the emergency department (ED). We assessed an antibiotic stewardship intervention tailored for the ED. The primary objective was improving overall adherence to agent choice and treatment duration. The secondary objective was a decrease in fluoroquinolone prescription.Methods: This pre-post study included patients discharged from the ED with a UTI diagnosis. The intensive intervention period lasted three months and involved dissemination of guidelines, short lectures, incorporation of order sets into electronic ED charts and weekly personal audit and feedback. The following 11-month phase was a booster period consisting of monthly text messages of the treatment protocol. Assessment of adherence to the protocol was compared between the three-month pre-intervention period and the last two months of the intensive intervention period, as well as with the last two months of the booster period.Results: A total of 177 patients were included in the pre-intervention period, 156 in the intervention period, and 94 in the late follow-up assessing the booster period. Median age was 49 (18-94) years, 78.2% were female, 84.8% had cystitis. During the intervention period, protocol adherence with antibiotic selection and duration increased from 41% to 84% (p < 0.001). Adherence remained high in the late follow-up period (73.4% vs. 41%, p < 0.001). Fluoroquinolone use decreased from 19.1% pre-intervention, to 5% in the intervention and 7.4% in the late follow-up periods (p < 0.001).Conclusions: An antibiotic stewardship intervention in a busy ED resulted in adherence to treatment protocols, including a decrease in fluoroquinolone use. A monthly reminder preserved most of the effect for a year. [ABSTRACT FROM AUTHOR]

Background: Lactate and lactate clearance are being used as biomarkers in several critical conditions. The aim of this study was to examine the value of sixth hour lactate clearance in patients who were hospitalized with chronic obstructive pulmonary disease (COPD) exacerbations.Methods: This single-center, cross-sectional study was conducted in a tertiary emergency department (ED) on patients who presented with acute exacerbation of COPD. Discharge or admission decisions were specified according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria and the clinician's decision. In the study, lactate clearance was defined as the percent decrease in lactate from the time of presentation to the ED to the sixth hour.Results: A total of 495 patients were evaluated and 397 patients were excluded. Among included patients, 53 (54.1%) were admitted to the hospital and 45 (45.9%) were discharged. The median lactate clearance was found to be -11.8% (95% CI: -50.0 to 34.5) in the admitted group and 14.7% (95% CI: -11.3 to 42.3) in the discharged group. Between the two groups, the median difference of lactate clearance was found to be 26.5% (95% CI: 0.6 to 52.4). Multivariate logistic regression analysis revealed that the delta lactate value can determine the hospitalization need of patients (OR: 0.91, 95% CI: 0.85 to 0.97).Conclusion: Lactate clearance can be evaluated as a useful marker in patients with COPD exacerbations. This study suggests that lactate monitoring in the ED has clinical benefits in addition to GOLD guidelines when deciding whether to discharge or hospitalize a patient. [ABSTRACT FROM AUTHOR]
