The purpose of this study was to describe the associations between individual health insurance and ambulance utilization using a national sample of patients who receive emergency department (ED) care. ⋯ Ambulance use varies by health insurance status. Medicaid coverage and lack of insurance are each independently associated with increased odds of ambulance use, suggesting a disproportionate role for emergency medical services (EMS) in the care of patients with limited financial resources.

Adolescents with a history of peer assault are known to report high rates of other risky behaviors. The characteristics of adolescents seeking care in the ED for acute assault-related injury are less well established. This knowledge deficit is particularly noticeable for adolescent female victims of peer assault. This study's objectives were: 1) to characterize the demographics and risk behaviors of youths presenting to the emergency department (ED) with acute assault-related injury and 2) to compare assaulted youths' demographic characteristics, past experiences with violence, and other risk behaviors by sex. ⋯ Male and female adolescents with acute assault-related injuries were very similar. Both reported extremely high rates of past year peer violence, assault-related injury, and substance use. The greater prevalence of some risk factors among adolescent females, such as depressive symptoms, dating aggression, and independent living status, should be further investigated.

Coronary angiography calcium score (CACS) is included for patients who receive coronary computed tomography angiography (CTA) as part of diagnostic testing for low-risk chest pain. Both tests add radiation exposure, and it is unclear whether the combination provides more information than either test alone. The objective was to asses if CACS = 0 determines freedom from coronary artery disease (CAD) and whether the addition of CACS to coronary CT angiography provides additional risk stratification information or helps predict 30-day cardiovascular outcomes. ⋯ In the study sample, elevated CACS was associated with a higher likelihood of underlying CAD on coronary CTA, but the addition of CACS to coronary CTA did not help predict 30-day cardiovascular events.

Diagnosing diabetic ketoacidosis (DKA) has traditionally required a venous blood gas (VBG) to obtain serum pH and a serum chemistry panel to obtain electrolyte values. Because newer blood gas analyzers have the ability to report electrolyte values and glucose in addition to pH, this diagnostic process could theoretically be condensed. However, neither the diagnostic accuracy of the VBG for DKA nor the agreement between the VBG electrolytes and the serum chemistry electrolytes, including sodium, chloride, and bicarbonate, has been evaluated in the context of acute hyperglycemia. The purpose of this study was to assess the accuracy of VBG electrolytes for diagnosing DKA using serum chemistry electrolytes measures as the criterion standard and to describe the correlation between VBG and serum chemistry electrolytes in a sample of hyperglycemic patients seen in the emergency department (ED). ⋯ The VBG electrolytes were 97.8% sensitive and 100% specific for the diagnosis of DKA in hyperglycemic patients. These preliminary findings support the use of VBG electrolytes in lieu of VBG along with serum chemistry analysis to rule in or rule out DKA.

In this hypothesis-generating study, we observe, identify, and analyze how emergency clinicians seek to manage work pressure to maximize patient flow in an environment characterized by delayed patient admissions (access block) and emergency department (ED) crowding. ⋯ To redress the linearity of most literature on patient flow, this study adopts a systems perspective and ethnographic methods to bring to light the dynamic role that individuals play, interacting with their work contexts, to maintain patient flow. The study provides an empirical foundation, uniquely discernible through qualitative research, about aspects of ED work that previously have been the subject only of discussion or commentary articles. This study provides empirical documentation of the moment-to-moment responses of emergency clinicians to work pressure brought about by factors outside much of their control, establishing the relationship between patient flow and work pressure. We conceptualize the ED as a dynamic system, combining socioprofessional influences to reduce and control work pressure in the ED. Interventions in education, practice, policy, and organizational performance evaluations will be supported by this systematic documentation of the complexity of emergency clinical work. Future research involves testing the five findings using systems dynamic modeling techniques.
