Survey of information exchange and advanced use of other health information technology in primary care settings: capabilities in and outside of the safety net.
This study’s aim was to estimate advanced use of health information technology (health IT) use in safety net versus nonsafety net primary care practices. The authors explored domains of patient engagement, population health management, and electronic information exchange. They examined organizational characteristics that may differently predict advanced use of IT across these settings. A cross-sectional analysis of a national survey of 1776 physician practices was conducted. Health IT use was found to be common across primary care practices, but advanced use of health IT functionalities ranged from only 30% to 50% use. A lag was found for advanced feature use with safety net practices. However, safety net practices who were members of a health system or practice network had comparable health IT capabilities to those in nonsafety net sites.

Growth in health information exchange with ACO market penetration.
This study’s objectives were to assess whether hospitals expand the network breadth of their health information exchange (HIE) partners after joining an accountable care organization (ACO) and to analyze whether this HIE network expansion effect varies across markets with differing levels of ACO penetration. The authors used data from the American Hospital Association Annual Survey and Information Technology Supplement to measure nonfederal acute care hospitals from 2014-2017. There was a 30.7% increase in HIE breadth for 0.35 partner types with ACO participation. This effect was larger for hospitals in high-ACO penetration markets (32% increase) and smaller for hospitals in low-ACO penetration markets (24.8% increase).

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.
