Comparative study of ED mortality risk of US trauma patients treated at level I and level II vs nontrauma centers.
The researchers used National Emergency Department Sample (NEDS) data to explore the hypothesis that severely injured trauma victims properly triaged to a level I or level II trauma center have significantly lower odds of death than those undertriaged to a non-trauma center. They found that trauma patients with Injury Severity Score of greater than 25 received most benefit from proper triage. Efforts to reduce undertriage should focus on this population.

Enhancing clinical content and race/ethnicity data in statewide hospital administrative databases: obstacles encountered, strategies adopted, and lessons learned.
Eight grant teams used Agency for Healthcare Research and Quality infrastructure development research grants to enhance the clinical content of and improve race/ethnicity identifiers in statewide all-payer hospital administrative databases. The authors concluded that creation of enhanced administrative databases to support comparative effectiveness research is difficult, particularly in the face of numerous challenges with recruiting data partners such as competing demands on information technology resources.

Medicaid dental coverage alone may not lower rates of dental emergency department visits.
This study examined county-level rates of ED visits for nontraumatic dental conditions in twenty-nine States in 2010 in relation to dental provider density and Medicaid coverage of nonemergency dental services. It found that county-level Medicaid-funded dental ED visit rates were lower in states where Medicaid covered nonemergency dental services than in other states, although this difference was not significant after other factors were adjusted for.

Explaining the paradoxical age-based racial disparities in survival after trauma: The role of the treating facility.
This study sought to determine if differences in outcomes at treating facilities can help explain age-based racial disparities in survival after trauma. For example, among patients older than 65 years, blacks had decreased odds of mortality compared with whites. It found that facility-based differences do not seem to explain this paradoxical age-based racial disparity after trauma observed in the older population.

Nationwide comparative impact of thoracic endovascular aortic repair of acute uncomplicated type B aortic dissections.
The objective of this study was to evaluate the impact of thoracic endovascular aortic repair (TEVAR) on mortality, morbidity, length of stay (LOS), and discharge status on patients with acute uncomplicated Type B aortic dissections (TBAD). It found that TEVAR for acute uncomplicated TBAD was associated with similar in-hospital mortality and renal failure as compared to medical management.

The value of linking hospital discharge and mortality data for comparative effectiveness research.
The purpose of this paper was to demonstrate the value of linking state community hospital discharge data to vital statistics death files for research by conducting a comparative effectiveness analysis. The analysis revealed that in the matched cohort, in-hospital and 30-day postdischarge mortality rates were significantly lower following endovascular aneurysm repair than open aneurysm repair, but differences in the 1- and 5-year rates were not statistically significant.
