Effectiveness of a Universally Offered Chlamydia and Gonorrhea Screening Intervention in the Pediatric Emergency Department

PurposeAdolescents represent more than half of the newly diagnosed sexually transmitted infections in the U.S. annually. Emergency departments (EDs) may serve as an effective, nontraditional setting to screen for chlamydia/gonorrhea (CT/GC). The objective was to evaluate the effectiveness of a universally offered CT/GC screening program in two pediatric ED settings.MethodsThis was a prospective, delayed start pragmatic study conducted over 18 months in two EDs within the same academic institution among ED adolescents aged 14–21 years with any chief complaint. Using a tablet device, adolescents were confidentially informed of CT/GC screening recommendations and were offered screening. If patients agreed to CT/GC testing, a clinical decision support tool was triggered to inform the provider and order testing. The main and key secondary outcomes were the proportion of CT/GC testing and positive CT/GC test results in each respective ED.ResultsBoth EDs experienced modest but statistically significant increases in CT/GC testing post- versus pre-intervention (main: 11.5% vs. 7.9%; confidence interval [CI]: 2.9–4.2; p < .0001 and satellite: 3.8% vs. 2.6%; 95% CI: .7–1.7; p < .0001). Among those tested, the positivity rate at the main ED did not significantly change post- versus pre-intervention (24.1% vs. 23.2%; 95% CI: ?1.9 to 3.8; p = .71) but significantly decreased at the satellite ED (7.6% vs. 14.8%; 95% CI: ?12.2 to ?2.2; p = .01).ConclusionsA universally offered screening intervention increased the proportion of adolescents who were tested at both EDs and the detection rates for CT/GC at the main ED, but patient acceptance of screening was low.

Neighborhood risk: Socioeconomic status and hospital admission for pediatric burn patients

BackgroundBurn injury continues to cause significant morbidity and mortality in the US pediatric population. Many studies using inpatient samples have found a relationship between low socioeconomic status (SES) and burn injury. The purpose of our study was to evaluate the association between SES and the likelihood of admission for Emergency Department (ED) visits for pediatric burn injury.Study designA retrospective database review of pediatric ED visits for burn injury from a statewide hospital system, from January 1, 2005 to December 31, 2014. SES was assigned using an eight factor Neighborhood Risk Index (NRI) created from census block group data, with a higher score indicative of lower SES. The outcome measure was ED visits admitted to inpatient care.ResultsWe analyzed a sample of 1845 pediatric ED visits for burn injuries. Most visits were discharged from the ED (88.4%) while 10.5% were admitted to inpatient care and 1.0% were transferred to another hospital. In a multivariable logistic regression model, patients from high risk areas (>75th percentile NRI) had 1.58 higher odds of inpatient admission compared to patients from low risk areas (<75th percentile NRI; 95% CI: 1.08–2.30), after adjusting for age, gender, ethnicity, distance to the hospital, and previous ED visit for burn injury in the past 30 days. In addition, for every 1-mile increase in distance, a child’s likelihood of admission increased by 6% (95% CI: 4–9%).ConclusionsChildren with a burn injury from the highest risk socioeconomic areas in Rhode Island had a higher likelihood of inpatient admission. Further research is needed to determine what factors associated with socioeconomic status impact this finding.     

Rehabilitación multimodal en cirugía de urgencias: ¿utopía o realidad?

Enhanced Recovery After Surgery (ERAS) constitutes the application of a series of perioperative measures based on the evidence, in order to achieve a better recovery of the patient and a decrease of the complications and the mortality. These ERAS programs initially proved their advantages in the field of colorectal surgery being progressively adopted by other surgical areas within the general surgery and other surgical specialties. The main excluding factor for the application of such programs has been the urgent clinical presentation, which has caused that despite the large volume of existing literature on ERAS in elective surgery, there are few studies that have investigated the effectiveness of these programs in surgical patients in emergencies. The aim of this article is to show ERAS measures currently available according to the existing evidence for emergency surgery.     

急诊内镜诊疗在结直肠癌根治术后吻合口出血中的应用

目的探讨结直肠癌根治术后吻合口出血病人使用急诊内镜检查及止血的安全性和有效性。方法回顾性分析华中科技大学同济医学院附属协和医院2014年1月至2019年11月结直肠癌根治术后吻合口出血行急诊内镜检查以及内镜下治疗的28例病人资料。结果28例病人包括直肠癌术后15例、左半结肠癌术后3例及右半结肠癌术后10例。上述病例均完成急诊内镜检查并接受内镜下止血治疗。仅1例直肠癌术后吻合口出血病人因合并吻合口漏经内镜下止血效果不佳,最终接受外科手术治疗;其余27例吻合口出血病人均经过内镜止血成功。所有病例住院期间无再发出血,内镜诊疗并未导致术后吻合口漏及穿孔。结论结直肠癌根治术后吻合口出血急诊内镜检查及止血的方案,不增加吻合口出血、穿孔及漏等风险。术后急诊内镜下止血是安全有效的治疗手段,能明显提高止血成功率,降低再手术率。在病人出血后8 h内行急诊内镜是非常关键的诊治措施。     

Factors influencing the length of emergency room stay and hospital stay in nonfatal bicycle accidents: A retrospective analysis

Purpose: Lengthy hospitalization places a burden on patients and healthcare resources. However, the factors affecting the length of hospital stay (LHoS) and length of emergency room stay (LERS) in non-fatal bicycle accidents are currently unclear. We investigated these factors to inform efforts to minimize hospitalization. Methods: We performed a retrospective analysis of data from non-fatal injured bicyclists admitted to the Emergency and Critical Care Center at Kyoto Medical Center between January 2012 and December 2016. We measured LHoS, LERS, mechanism of injury, head injury prevalence, polytrauma, operations performed, injury severity score (ISS), abbreviated injury scale (AIS) score, maximum AIS score, and trauma and injury severity score probability of survival. We conducted multiple regression analysis to determine predictors of LHoS and LERS. Results: Within the study period, 82 victims met the inclusion and exclusion criteria and were included. Mean age was (46.0 ± 24.7) years. Overall mean LHoS was (16.8 ± 25.2) days, mean LERS was (10.6 ± 14.7) days, median ISS was 9 (interquartile range (IQR): 3-16), median maximum AIS was 3 (IQR: 1-4), and median trauma and injury severity score probability of survival was 98.0% (IQR: 95.5%-99.6%). Age, maximum AIS, ISS, and prevalence of surgery were significantly greater in long LHoS and LERS group compared with short LHoS and LERS group (p < 0.05). Performance of surgery independently explained LHoS (p = 0.0003) and ISS independently explained LERS (p = 0.0009). Conclusion: Surgery was associated with long hospital stays and ISS was associated with long emergency room stays. To improve the quality life of the bicyclists, preventive measures for reducing injury severity or avoiding injuries needing operation are required.
