The role of electronic health record developers in hospital patient sharing.
This study’s objective was to determine whether hospital adoption of a new electronic health record (EHR) developer increases patient sharing with hospitals using the same developer. Data was extracted on patients shared with other hospitals for 2076 US nonfederal acute care hospitals from the 2011 to 2016 CMS Physician Shared Patient Patterns database. The authors calculated the ratio of patients shared with hospitals outside of the focal hospital’s network that use the same EHR developer as the focal hospital. Switching to a new developer increased the ratio of patients shared with other hospitals using the same developer by 4.1-19.3%, depending on model specification. Magnitude of this effect varied by EHR developer and was increasing in developer market share.

Impact of the 2015 Health Information Technology Certification Edition on interoperability among hospitals.
Most nonfederal acute care hospitals use electronic health records (EHRs) certified by the Office of the National Coordinator for Health Information Technology. In 2015, the Office of the National Coordinator for Health Information Technology finalized the 2015 Health IT Certification Edition and adoption by hospitals began in 2016. In this study, the investigators examined the impact of the 2015 Edition on rates of interoperable exchange among nonfederal acute hospitals.

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.

Does participation in health information exchange improve hospital efficiency?.
This study strives to answer the question: does health information exchange (HIE) network participation improve hospital efficiency? The results of the study suggest that hospital investment in HIE participation may be a useful strategy to improve hospital operational performance, and that policy should continue to support increased participation and use of HIE.

An observational study of the relationship between meaningful use-based electronic health information exchange, interoperability, and medication reconciliation capabilities.
Stagnation in hospitals' adoption of data integration functionalities coupled with reduction in the number of operational health information exchanges could become a significant impediment to hospitals' adoption of 3 critical capabilities: electronic health information exchange, interoperability, and medication reconciliation, in which electronic systems are used to assist with resolving medication discrepancies and improving patient safety. This observational study examines the relationship between meaningful use-based electronic health information exchange, interoperability, and medication reconciliation capabilities.
