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.

A randomized trial to train vulnerable primary care patients to use a patient portal.
This study examined the use of patient care portals in primary care practices with vulnerable patients such as those with lower socioeconomic status or limited health literacy (LHL). A randomized control trial was created with 93 English-speaking patients with 1+ chronic diseases. The patients were provided with either an 1) in-person tutorial with a research assistant, or 2) a link to view the videos on their own. A third arm of the trial were control patients with just normal access to get to the portal. There was a higher rate of access (21%) after the trial was over with the two intervention groups as compared with 9% for the usual care patients.

Health information exchanges (HIEs) are expected to improve poor information coordination in emergency departments (EDs); however, whether and when HIEs are associated with better operational outcomes remains poorly understood. In this paper, the authors study HIE and length of stay (LOS) relationship using a large dataset from the Healthcare Cost and Utilization Project consisting of about 7.4 million treat‐and‐release visits made to 63 EDs in Massachusetts.

Alternative payment models and hospital engagement in health information exchange.
The purpose of this study was to assess whether hospital participation in alternative payment models (APMs) was associated with greater engagement in health information exchange (HIE) along 4 dimensions: volume of patients for whom information is exchanged, diversity of information types, breadth of partner types, and depth of technical approach. Findings suggest that APM participation was associated with greater HIE diversity, breadth, and depth that value-based payment may be spurring improvements in HIE infrastructure; however, the finding that APM participation is associated with lower HIE volume suggests that there may be incentive to focus HIE investments on a limited number of partners.
