Background: Acute coronary syndrome (ACS) is a common diagnosis in the emergency department (ED). Missing this diagnosis may lead to increased morbidity or mortality. With improved cardiac biomarkers tests, it is unknown if that has decreased the prevalence of ACS diagnoses in ED patients who were recently evaluated in the ED. Methods: This is a retrospective review of ED patients who were diagnosed with ACS and seen in the ED 7 and 30 days before that visit in North Texas between 2009 and 2015. The demographics and temporal trends of missed ACS rates are described. Logistic regression was used to evaluate if any factors (ie, age, ethnicity, sex, insurance status) were significant. Results: Between December 26, 2008 and June 29, 2015, there were 24,914 diagnoses of ACS in the ED. The overall prevalence of patients diagnosed with ACS 7 days after their ED visit was 3.2% and 8.8% at 30 days. For patients diagnosed with ACS 7 days and 30 days after an ED visit, the most common initial ED diagnoses were nonspecific chest pain (57.7%), atherosclerotic disease (19.5%), and heart failure (12.8%). Between 2009 and 2015, there was no overall change in the rate of ACS diagnoses in patients seen 7 or 30 days before an ED visit. Conclusions: The prevalence of missed ACS in the North Texas region at 7 and 30 days after the initial ED visit is low and has not changed over the past several years.

Neonatal mortality in Africa is among the highest in the world. In Liberia, providers face significant challenges due to lack of resources, and providers in referral centers need to be prepared to appropriately provide neonatal resuscitation. A team of American Heart Association health care providers taught a two-day neonatal resuscitation curriculum designed for low-resource settings at a regional hospital in Liberia. The goal of this study was to evaluate if the curriculum improved knowledge and comfort in participation. The curriculum included simulations and was based on the Neonatal Resuscitation Protocol (NRP). Students learned newborn airway management, quality chest compression skills, and resuscitation interventions through lectures and manikin-based simulation sessions. Seventy-five participants were trained. There was a 63% increase in knowledge scores post training (p < 0.00001). Prior cardiopulmonary resuscitation (CPR) training, age, occupation, and pre-intervention test score did not have a significant effect on post-intervention knowledge test scores. The median provider comfort score improved from a 4 to 5 (p < 0.00001). Factors such as age, sex, prior NRP education, occupation, and post-intervention test scores did not have a significant effect on the post-intervention comfort level score. A modified NRP and manikin simulation-based curriculum may be an effective way of teaching health care providers in resource-limited settings. Training of providers in limited-resource settings could potentially help decrease neonatal mortality in Liberia. Modification of protocols is sometimes necessary and an important part of providing context-specific training. The results of this study have no direct relation to decreasing neonatal mortality until proven. A general resuscitation curriculum with modified NRP training may be effective, and further work should focus on the effect of such interventions on neonatal mortality rates in the region.

Liberia is a low‐income country in West Africa that has faced significant challenges, including a civil war and the recent Ebola epidemic. Little data exists on the more current post‐war and pre‐Ebola trends of child health in Liberia in the rural setting. This study is a retrospective chart review of pediatric mortality in 2013 at a rural tertiary care center in Liberia, 10 years post‐war. From January 2013 to December 2013, there were 50 pediatric deaths, or 5.4% of the 920 total pediatric admissions. The most common cause of neonatal death was sepsis, and the most common cause of death under five years of age was malaria. The majority (82.0%) of the deaths were in children under five. Pediatric mortality at this hospital was similar to other reported mortality six years post‐war, and lower than that reported immediately post‐war. Neonatal sepsis and malaria are two significant causes of pediatric mortality in this community and, therefore, further efforts to decrease childhood mortality should focus on these causes.

The purpose of this cross-sectional survey study is to quantitatively examine the differences in patient trust towards physicians between four different clinical departments in a Chinese hospital. Using a validated modified Chinese version of the Wake Forest Physician Trust Scale, we measured patient trust in each department, and also collected data on patient demographics. A total of 436 patients or family members were surveyed in the departments of emergency medicine, pediatrics, cardiology, and orthopedic surgery. Significant differences were found between the departments, especially between pediatrics (trust score 43.23, range 11–50) and emergency medicine and cardiology (trust scores 45.29 and 45.79, respectively with range of 11–50). The average total score across all four departments was 44.72. There are indications that specifically comparing departments, such as patient demographics or department structure, could be helpful in tailoring patient care to improve physician-patient relationships.
