Health information exchange improves identification of frequent emergency department users.
The goal of the project was to measure the incremental increase in the number of frequent ED users who were identified when data
from all EDs participating in an health information exchange were compared with site-specific data. When the researchers analyzed HIE-wide data instead of site-specific data, they identified 20.3 percent more frequent ED users and 16.0 percent more visits by them to the ED.

Form CMS-2728 data versus erythropoietin claims data: implications for quality of care studies.
The purpose of this study was to compare predialysis erythropoietin-simulating agents (ESA) care reported on Form CMS-2728 with Medicare claims for ESA treatment submitted for patients 67 years and older at initiation of dialysis with Medicare as the primary payer. It found that the agreement between Form CMS-2728 and claims data is poor and discordant results are observed when comparing the use of these data sources to predict health outcomes.

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.

An efficient pancreatic cyst identification methodology using natural language processing.
Accurate identification, surveillance and treatment of pancreatic cysts represents an opportunity to prevent pancreatic cancer. Much information about pancreatic cysts can be found in free text format in various narrative medical reports. To capture this information, the researchers modified their cyst identification technique using the Unstructured Information Management Architecture (UIMA) pipeline.
