Health systems' use of enterprise health information exchange vs single electronic health record vendor environments and unplanned readmissions.
Enterprise health information exchange (HIE) and a single electronic health record (EHR) vendor solution are 2 information exchange approaches to improve performance and increase the quality of care. This study sought to determine the association between adoption of enterprise HIE vs a single vendor environment and changes in unplanned readmissions. The investigators concluded that reductions in the probability of an unplanned readmission after a hospital adopts a single vendor environment suggested that HIE technologies can better support the aim of higher quality care.

The associations between query-based and directed health information exchange with potentially avoidable use of health care services.
This study quantified the impact of directed and query-based approaches to health information exchange (HIE) on potentially avoidable use of health care services. Data from Medicare fee-for-service claims was examined from 2008 to 2014 from providers in the Rochester Regional Health Organization (RHIO). There were very small reductions in the probability of ambulatory care sensitive hospitalization with either approach.

Hospitals' adoption of intra-system information exchange is negatively associated with inter-system information exchange.
This study examined hospitals’ adoption of interoperability of health information technology (HIT). The relationship between hospitals’ intra- (within the same organization) and inter-system information exchange capabilities was explored using data from the 2010-2014 American Hospital Association’s Annual Health Information Technology Survey. As expected, there was more intra-system information exchange than inter-system but as time went on inter-system information exchange has increased. During the study period, hospitals were sharing 4.6 types of information by intra-system exchange, but only 2.7 types of information by inter-system exchange.
