Enabling health information exchange at a US poison control center.
This paper discusses the development and implementation of a poison control center (PCC) to participate in a standards-based health information exchange (HIE). This was previously not possible due to software noncompliance with HIE standards, lack of informatics infrastructure, and the need to integrate HIE processes into workflow. The investigators adapted the Health Level Seven Consolidated Clinical Document Architecture (C-CDA) consultation note for the PCC use case. They developed software called SNOWHITE that enables PCC HIE in tandem with a poisoning information center. It was successfully implemented at the Utah PCC starting in February 2017 through October 218.

Improving notifiable disease case reporting through electronic information exchange-facilitated decision support: a controlled before-and-after trial.
This study examined the results of implementing an electronic, prepopulated notifiable disease report form on case reporting rates by ambulatory care clinics to public health authorities. They conducted a 2-year controlled before-and-after trial of a health information exchange (HIE) in Indiana. Data was analyzed from electronic prepopulated reports and paper and fax reports submitted to a local health department for 7 conditions by using a difference-in-differences model. Provider reporting rates for chlamydia and gonorrhea increased significantly during the baseline period. During the intervention period they decreased significantly in control clinics. Completion and timeliness improved for both intervention and control clinics.

Hospital adoption of multiple health information exchange approaches and information accessibility.
The aim of this study was to determine the change in adoption of 3 types of electronic health information exchange (HIE) in hospitals for 3 types of information exchange: secure messaging, provider portals, and use of an HIE; and to assess if growth in each approach corresponded to an increased ability to access and integrate patient information from outside providers. A sample of 1917 hospitals that responded to the American Hospital Association Information Technology Supplement every year from 2014 to 2016 was used for the analysis. Adoption of each approach increased by 9-15 percentage points over that time. The average number of HIE approaches increased from 1.0 to 1.4. The likelihood of having outside information increased by 10.3 percentage points with adoption of 1 approach, and by 9.5 percentage points with adoption of a second approach.

Sharing information electronically with other hospitals is associated with increased sharing of patients.
This study examined whether patient sharing between hospitals increased when they participated in a health information organization (HIO). The researchers used national data on hospital participation in HIOs from the American Hospital Association Information Technology Supplement and data on the volume of Medicare patients shared between pairs of hospitals from 2010 to 2016. They found that there an increase in patient sharing in competitive markets and with larger hospitals. Participation by only one hospital had no impact on patient sharing.

The complementary nature of query-based and directed health information exchange in primary care practice.
Many policymakers and advocates assume that directed and query-based health information exchange (HIE) work together to meet organizations' interoperability needs, but this is not grounded in a substantial evidence base. This study sought to clarify the relationship between the usage of these 2 approaches to HIE. The investigators concluded that quantitative and qualitative findings suggested that directed and query-based HIE existed in a complementary manner in ambulatory care settings.
