简要总结
Three out of four Veterans receive a portion of their care from non-VA providers. On April 9, 2009, President Barack Obama directed the Department of Veterans Affairs and the Department of Defense to create the Virtual Lifetime Electronic Record (VLER). On August 2010, Secretary of Veterans Affairs Eric K. Shinseki visited Indianapolis, and after visiting with leaders from the VA Health Services Research & Development (HSR&D) Center of Excellence and the Regenstrief Institute, he made the following public comments regarding the latest partnership between the two institutions: "This new technology allows safer, more secure, and private access to electronic health information which, in turn, enhances our ability to continue providing Veterans with the quality care that they have earned."
This new technology refers to the VLER HEALTH program that the Indianapolis VA is now implementing in partnership with the Regenstrief Institute and Indiana Health Information Exchange (IHIE). This VA-IHIE demonstration project is intended to create the capacity for VA institutions to exchange health information with community partners.
Investigators from the VA HSR&D Center on Implementing Evidence-Based Practice are active collaborators in building and implementing this program. The VA-IHIE program provides the bi-directional exchange of health information between VA and non-VA providers. Based on our pilot study of linked VA-IHIE data, investigators are conducting an evaluation of the impact of the VA-IHIE demonstration project upon health care quality and cost of Veterans by taking advantage of the initiation of the implementation as a natural experiment.
详细描述
This study will perform a pre-post evaluation of the VA-IHIE implementation, with a concurrent control group, among Veterans seen at the Indianapolis VA. Data on care received by Veterans will be obtained for one year before, and one year after, VA-IHIE enrollment. Patients will be recruited into the VA-IHIE program in a rolling manner over the course of a year, and thus will have different calendar intervals of follow-up. For purposes of evaluation, investigators will approach the VA-IHIE implementation as a patient-directed intervention given that additional information available from the exchange is available only on a patient-by-patient basis, i.e., a provider cannot use exchange information available for one patient in the care of another. Although the VA-IHIE program will be implemented at the site level, patients will be enrolled individually.

结局指标
主要结局
Health Care Quality: Affect of HIE on LDL Levels of Participants.
时间窗: 3 years
This study will measure the impact of HIE upon health care quality the underuse of ambulatory care services for diabetics. Measurements of underuse before and after implementation will detect improvements in the quality of care. To measure underuse, the study employs a measurement set that is sensitive to the potential effects and feasible for electronic data capture. In this specific instance, we expect the LDL levels to reflect lower numbers among diabetics due to greater health management via information sharing.
Understanding Utilization of Healthcare Procedures by Veterans According to Source of Data
时间窗: 2 years
Determining rates of usage of healthcare by veterans by source of data. This will clue us into any differences in utilization patterns between groups.
Effect of Health Information Exchange on Cost
时间窗: 2 Years
Before after analysis of the presence of health information exchange on costs within the VA healthcare system; Measure is cost, unadjusted, in dollars for the year post enrollment in the health information exchange
