To optimize health care utilization, health outcomes, and costs, research is needed to improve an understanding of frequent users of emergency health services. Frequent use of emergency services is associated with high costs of health care and may be indicative of challenges accessing, or poor outcomes of, health care. Patient demographics and health factors related to frequent use of the emergency medical services (EMS) system of a midsized city were identified. Study findings will aid in the development of targeted interventions to improve population health. ⋯ The study findings revealed the major role of chronic somatic and behavioral health problems in frequent EMS use and that rates of frequent use were highest among those middle-aged, African American, and male. These results suggest the need for coordination of EMS with community-based, integrated medical and behavioral health services to improve access and use of preventive services, with implications for health outcomes and costs. This study demonstrates the value of EMS patient data in identifying at-risk populations and informing novel, targeted approaches to public health interventions.

Randomized Controlled Trial
Value of Point-of-care Ketones in Assessing Dehydration and Acidosis in Children With Gastroenteritis.
Children with gastroenteritis often develop dehydration with metabolic acidosis. Serum ketones are frequently elevated in this population. The goal was to determine the relationship between initial serum ketone concentration and both the degree of dehydration and the magnitude of acidosis. ⋯ Children with gastroenteritis and dehydration have elevated serum ketone concentrations that correlate with both degree of dehydration and magnitude of metabolic acidosis. Point-of-care serum ketone measurement may be a useful tool to inform management decisions at the point of triage or in the initial evaluation of children with gastroenteritis and dehydration.

Multicenter Study
Generalizability of a Simple Approach for Predicting Hospital Admission From an Emergency Department.
The objective was to test the generalizability, across a range of hospital sizes and demographics, of a previously developed method for predicting and aggregating, in real time, the probabilities that emergency department (ED) patients will be admitted to a hospital inpatient unit. ⋯ The accuracy of regression models to predict ED patient admission likelihood was shown to be generalizable across hospitals of different sizes, populations, and administrative structures. Each hospital used a unique combination of predictive factors that may reflect these differences. This approach performed equally well when hospital staff coded patient data in real time versus the research team retrospectively.

Observational Study
ST2 in Emergency Department Patients With Noncardiac Dyspnea.
Serum levels of soluble ST2, a member of the interleukin-1 receptor family, predict mortality in emergency department (ED) patients with dyspnea secondary to acute heart failure and acute coronary syndrome. Elevated levels of ST2 have also been described in pulmonary disease, but it is unclear if these are associated with adverse outcomes. The hypothesis for this study was that elevated ST2 levels would be associated with 180-day mortality and 180-day return ED visits or hospital readmission in patients presenting to the ED with noncardiac causes of dyspnea. ⋯ Patients with noncardiac dyspnea who died or required readmission to the hospital within 180 days had higher levels of ST2 compared with nonadmitted survivors. Further research into ST2 as a prognostic tool in pathologic processes not involving the heart, such as pulmonary disease, is warranted.

Multicenter Study Comparative Study
A Cost-effectiveness Analysis Comparing a Clinical Decision Rule Versus Usual Care to Risk Stratify Children for Intraabdominal Injury After Blunt Torso Trauma.
Modelling implementation of a clinical decision rule to identify children at very low risk of significant intra-abdominal injury after blunt trauma:
- Saved on average US$55 per child.
- Avoided a CT scan in 1 in 10 children.
- Missed 1 in 2,000 intra-abdominal injuries requiring acute intervention.
