Interoperability of health-related social needs data at US hospitals.
The objective of this study was to measure hospital engagement in interoperable exchange of health-related social needs (HRSN) data. Hospitals that participated in accountable care organizations or patient-centered medical homes and hospitals were more likely to receive external HRSN data. For-profit hospitals and public hospitals were less likely to participate in HRSN data exchange.

A unified approach to health data exchange: a report from the US DHHS.
To improve the accessibility and interoperability of electronic health information, the U.S. Department of Health and Human Services proposed a national strategy built around three key components: the United States Core Data for Interoperability, FHIR (Fast Healthcare Interoperability Resources), and the Trusted Exchange Framework and Common Agreement. This report outlines how these components provide the foundation for seamless, standardized, and secure health data exchange across systems and care settings. By enabling real-time access to data, the strategy supports improved patient care, health system efficiency, and research capabilities. The authors emphasize that full realization of these goals depends on continued public-private collaboration.

Assessing progress toward the vision of a comprehensive, shared electronic care plan: scoping review.
People with multiple chronic conditions often receive care from a broad array of clinicians across multiple health care settings, making it difficult to share care plans between those facilities and providers. One method for possibly improving care for those individuals is through the development and use of comprehensive, shared, electronic care (e-care) plans. The purpose of the study was to review existing e-care plans and related initiatives that could be utilized to develop a comprehensive, shared e-care plan, and facilitate the National Institutes of Health and 大象视频 joint initiative鈥檚 creation of e-care planning tools for people with multiple chronic conditions. The researchers conducted a review of literature from 2015-2020, as well as interviews of expert informants to identify information missing from the literature search. The study identified 7 different interventions for e-care plans and 3 different projects for health care data standards, all of which included elements which could be utilized to further the goals of developing a comprehensive, shared e-care plan. The study concluded that while none of the existing interventions met all the optimal e-care plan criteria for people with multiple chronic conditions, each plan included the infrastructure necessary to progress toward that goal. The researchers reported that gaps must first be addressed, but that a comprehensive, shared e-care plan can improve care coordination across multiple care settings and clinicians.

Growth in health information exchange with ACO market penetration.
This study鈥檚 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).

Strategic use of health information exchange and market share, payer mix, and operating margins.
The purpose of this study was to identify the impact of hospitals' use of Health information exchange (HIE) capabilities on outcomes that may be sensitive to changes in different contracting arrangements and referral patterns occurring as a result of improved connectivity. The researchers utilized a panel of community hospitals in nine states and explored the relationship between the number of different data types the hospital could exchange via HIE and changes in market share, payer mix, and operating margin. The study found that an increase in HIE capability was related with a 13% increase in a hospital's discharges that were covered by commercial insurers or Medicare. Increasing intraorganizational sharing of information was related with a 9.6% decrease in the percentage of discharges covered by commercial insurers or Medicare. There was no relationship between increasing HIE capability or intraorganizational information sharing and increased market share or operating margin. CONCLUSIONS: Improving information sharing with external organizations may be an approach to support strategic business goals. PRACTICE IMPLICATIONS: Organizations may be served by identifying ways to leverage HIE instead of focusing on intraorganizational exchange capabilities.

The role of electronic health record developers in hospital patient sharing.
This study鈥檚 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鈥檚 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.

Information blocking remains prevalent at the start of 21st Century Cures Act: results from a survey of health information exchange organizations.
This study鈥檚 objective was to assess the prevalence of information blocking of patient data by health systems, electronic health record (EHR) vendors, and others prior to enforcement of new rules to prevent this practice. A national survey of health information exchange organizations (HIEs) was conducted. Eighty-four percent of 106 HIEs who met the inclusion criteria responded. The majority (55%) of HIEs reported that EHR vendors routinely engage in information blocking at least some of the time. The most common blocking behavior of EHR vendors was setting unreasonably high prices which was reported by 42% of HIEs. Behavior health systems most common information blocking behavior was refusing to share information, which was routinely observed by 14% of HIEs. Reported levels of vendor information blocking was related to regional competition among vendors and information blocking was more highly concentrated in some geographic regions than others.

Trends in user-initiated health information exchange in the inpatient, outpatient, and emergency settings.
Prior research on health information exchange (HIE) typically measured provider usage through surveys or they summarized the availability of HIE services in a healthcare organization. Few studies utilized user log files. Using HIE access log files, the investigators measured HIE use in real-world clinical settings over a 7-year period (2011-2017). They found that use of HIE increased in inpatient, outpatient, and emergency department (ED) settings.

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.

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.

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.

Notifiable condition reporting practices: implications for public health agency participation in a health information exchange.
The researchers sought to better understand the barriers to and burden of notifiable condition reporting from the perspectives of clinic physicians, interviews with clinic reporters, and interviews with public health workers involved in reporting workflow. A strong recommendation generated by their findings is that, given their central role in reporting, clinic reporters are a significant target audience for public health outreach and education that aims to alleviate perceived reporting burden and improve reporting knowledge.

Comparison of consumers' views on electronic data sharing for healthcare and research.
The researchers surveyed California consumers to learn their views of privacy, security, and consent in electronic data sharing for healthcare and research together. They found considerable concern that health information exchanges will worsen privacy (40.3 percent) and security (42.5 percent). Consumers are in favor of electronic data sharing but elements of transparency are important: individual control, who has access, and the purpose for use of data.

Assessing the adequacy of the HL7/LOINC Document Ontology Role axis.
This study assessed the adequacy of the Role axis for representing the type of author documenting care. Experts used a master list of 220 values created from seven resources and established mapping guidelines. Baseline certification, licensure, and didactic training were identified as key parameters that define roles and hence often need to be pre-coordinated. Document Ontology (DO) was inadequate in representing 82 percent of roles, and this gap was primarily due to lack of granularity in DO.

Despite substantial progress in EHR adoption, health information exchange and patient engagement remain low in office settings.
The authors investigated the growth of EHR adoption. They found gaps in EHR adoption, with physicians in solo practices and non-primary care specialties lagging behind others; exchange with other providers was limited, with only 14 percent sharing data with providers outside their organization; and 24 percent routinely provided patients with the ability to view online, download, or transmit their health record.
