Background: Diagnostic uncertainty exists surrounding the identification of radiographic pneumonia in children with wheeze. It is important to determine the prevalence and clinical predictors of pneumonia in this population to limit chest radiography (CXR) and promote judicious antibiotic use.

Objectives: The objectives were to (1) estimate the prevalence of radiographic pneumonia in children with wheeze and (2) systematically review the diagnostic accuracy of clinical findings for the identification of radiographic pneumonia.

Methods: Data sources were MEDLINE, PubMed Central, Cochrane Library, CINAHL, and Web of Science (January 1995 to September 2023). For study selection, two reviewers identified high-quality studies reporting on clinical characteristics associated with radiographic pneumonia in wheezing children (age 0-21 years). Using Covidence software, data regarding study characteristics, methodologic quality, and results were extracted. Data were pooled using random-effects meta-analysis.

Results: A total of 8333 unique titles and abstracts were reviewed. Twelve studies, representing 7398 patients, were included. Fifteen percent of children with wheeze undergoing CXR had pneumonia. Findings associated with radiographic pneumonia included temperature ≥ 38.4°C (positive likelihood ratio [LR+] 2.1, 95% CI 1.2-3.6, specificity 85%), oxygen saturation < 92% (LR+ 3.6, 95% CI 1.4-8.9, specificity 89%), and grunting (LR+ 2.7, 95% CI 1.6-4.4, pooled specificity 91%). Factors associated with the absence of radiographic pneumonia included lack of fever (negative likelihood ratio [LR-] 0.67, 95% CI 0.52-0.85) and oxygen saturation ≥ 95% (LR- 0.64, 95% CI 0.42-0.98). Tachypnea and auscultatory findings were not associated with radiographic pneumonia.

Discussion: Heterogeneity across studies limits generalizability. Additionally, all included studies overestimate the rate of radiographic pneumonia given the fact that all subjects had a CXR performed due to clinical suspicion of pneumonia.

Conclusions: Radiographic pneumonia occurs in 15% of wheezing children undergoing CXR for pneumonia. Auscultatory findings and tachypnea do not differentiate children with and without pneumonia, and the rate of radiographic pneumonia is very low in the absence of fever and hypoxemia.

Objective: The objective was to systematically review all studies focusing on barriers, facilitators, and tools currently available for shared decision making (SDM) in emergency departments (EDs).

Background: Implementing SDM in EDs seems particularly challenging, considering the fast-paced environment and sometimes life-threatening situations. Over 10 years ago, a previous review revealed only a few patient decision aids (PtDAs) available for EDs.

Methods: Literature searches were conducted in MEDLINE, Embase, and Cochrane library, up to November 2023. Observational and interventional studies were included to address barriers or facilitators for SDM or to investigate effects of PtDAs on the level of SDM for patients visiting an ED.

Results: We screened 1946 studies for eligibility, of which 33 were included. PtDAs studied in EDs address chest pain, syncope, analgesics usage, lumbar puncture, ureterolithiasis, vascular access, concussion/brain bleeding, head-CT choice, coaching for elderly people, and activation of patients with appendicitis. Only the primary outcome was meta-analyzed, showing that PtDAs significantly increased the level of SDM (18.8 on the 100-point OPTION scale; 95% CI 12.5-25.0). PtDAs also tended to increase patient knowledge, decrease decisional conflict and decrease health care services usage, with no obvious effect on overall patient satisfaction. Barriers and facilitators were identified on three levels: (1) patient level-emotions, health literacy, and their own proactivity; (2) clinician level-fear of medicolegal consequences, lack of SDM skills or knowledge, and their ideas about treatment superiority; and (3) system level-time constraints, institutional guidelines, and availability of PtDAs.

Conclusions: Circumstances in EDs are generally less favorable for SDM. However, PtDAs for conditions seen in EDs are helpful in overcoming barriers to SDM and are welcomed by patients. Even in EDs, SDM is feasible and supported by an increasing number of tools for patients and physicians.

Background: Drowning is a preventable public health concern that burdens emergency care systems globally. This study comprehensively evaluated fatal drowning patterns across population, time, and geography from 1990 to 2021 to inform effective prevention strategies.

Methods: Using the 2021 Global Burden of Disease Study framework and standardized estimation methods, the study analyzed global and regional drowning burden in terms of mortality, incidence, and disability-adjusted life-years (DALYs), based on population registry data and drowning-related epidemiological covariates.

Results: Global drowning incidents decreased by 33.67% from 1990 to 2021. The drowning incidence rate and mortality rate declined from 24.20 and 9.68 per 100,000 in 1990 to 10.85 and 3.48 per 100,000 in 2021, respectively. Years of life lost and DALYs rates due to drowning also decreased significantly, from 715.80 and 718.69 per 100,000 in 1990 to 197.64 and 198.92 per 100,000 in 2021. Regionally, East Asia had the highest drowning mortality (27.15% of global deaths), while the high-income Asia Pacific region experienced the highest incidence rate (21.38 per 100,000). South Asia had the greatest number of drowning deaths (75,639). Tropical Latin America showed the largest incidence decline, while high-income Asia Pacific exhibited increasing trends. Drowning disproportionately affected children under 5 and the elderly in most regions.

Conclusions: While global drowning rates have declined, progress varies across regions. To improve prevention, focus should target low-income/middle-income countries and vulnerable populations like children and the elderly. Increased investment in safety education and rescue resources is vital to address their disproportionate risks.

Objective: Renal colic (RC) is a common urologic emergency often leading to significant pain and recurrent hospital visits. This study aimed to compare the efficacy and safety of piroxicam versus paracetamol in preventing pain recurrence and hospital readmission in patients treated for RC and discharged from the emergency department (ED).

Methods: A prospective, randomized, single-blind trial was conducted in four EDs. Eligible adults with RC were randomized to receive oral piroxicam, paracetamol, or placebo for 5 days post-ED discharge. Primary outcomes included pain recurrence and ED readmission within 7 days. Secondary outcomes included time to recurrence and treatment-related side effects.

Results: Of 1383 enrolled patients, no significant differences were observed among the groups regarding baseline characteristics. Pain recurrence rates within 7 days were 29% (95% confidence interval [CI] 24.9%-33.2%) for piroxicam, 30.3% (95% CI 26.1%-34.5%) for paracetamol, and 30.8% (95% CI 26.6%-35.0%) for placebo, with no significant between-group differences (p = 0.84). Among patients experiencing recurrence, the majority encounter it within the initial 2 days following their discharge (86% in the piroxicam group, 84.1% in the paracetamol group, and 86% in the placebo group, respectively). ED readmission rates were similar across groups: 20.8% (95% CI 17.1%-24.5%) in the piroxicam group, 23.8% (95% CI 19.9%-27.7%) in the paracetamol group, and 22.9% (95% CI 19.1%-26.8%) in the placebo group (p = 0.52). The piroxicam group reported significantly higher adverse effects compared to others.

Conclusions: Piroxicam and paracetamol did not demonstrate efficacy in preventing pain recurrence or ED readmission within the first week following RC treatment.

Advancing care in Emergency Medicine (EM) requires the development of well-trained researchers, but our specialty has lower amounts of research funding compared to similar medical fields. Increasing the number of pathways available for research training supports the growth of new investigators. To address the need for more EM researchers, the Society of Academic Emergency Medicine and the American College of Emergency Physicians convened a Federal Research Funding Workgroup. Here, we report the workgroup recommendations regarding the creation of Research Training Fellowships using the T32 grant structure sponsored by the National Institutes of Health. After reviewing the history of NIH-grant supported research fellowships in EM, we outline the rationale and describe the core components of T32-supported research fellowships, including program design, fellow evaluation, and recruitment considerations.
