CIS 665 WEEK 8
Page 1: Introduction to HIE
Health Information Exchange (HIE): A critical concept in health informatics that facilitates the exchange of health-related information across organizations.
Presented by Suhila Sawesi, Ph.D., MPharm, Bpharm, from the Health Informatics and Bioinformatics Program, College of Computing, GVSU, with modifications from William Hersh.
Page 2: Definitions and Challenges in HIE
HIE Definitions: A structured sharing of health information among medical entities, which involves various applications and frameworks.
Major components include implementations, system security, and medical records management.
Discusses challenges faced in the execution of HIE systems and the principles required for effective implementation.
Page 3: Limitations of Individual EHRs
A single organization's Electronic Health Record (EHR) is often insufficient due to patient mobility.
Statistics: In Massachusetts, 31% of patients visited multiple facilities; in Indiana, 40% had records spread across EDs.
Highlights the necessity for robust HIE, especially in public health contexts amid emerging diseases and bioterrorism threats.
Page 4: Definition of Health Information Exchange
HIE enables "anytime, anywhere access to clinical information for patient care."
Quotes from health informatics leaders emphasize the concept of "data following the patient" and electronic sharing among various healthcare entities.
Investments under HITECH reflect the growing recognition of HIE's importance, amounting to $564 million in grants.
Page 5: Historical Context of Information Sharing
Information sharing via HIE is not novel; established systems such as ATMs, airline reservations, and wireless networking serve as precedents.
Page 6: Types of HIE
Directed HIE: Information is directly sent and received to support planned care (e.g., referrals).
Query-based HIE: Information is retrieved to support unplanned care (e.g., emergency interventions).
Consumer-mediated HIE: Allows consumers to aggregate and manage their own health information.
Page 7: Implementations of HIE
Highlights successful implementations of HIE in the Indiana Health Information Exchange (IHIE) and other U.S. and international examples, along with noted failures.
Page 8: Overview of Indiana Health Information Exchange (IHIE)
Launched in the mid-1990s, previously known as the Indiana Network for Patient Care (INPC).
It features a centralized clinical repository, a secure network for clinical data messaging, and formal agreements among participants emphasizing HIPAA compliance.
Page 9: Participants in INPC
Includes major hospitals, national and regional laboratories, public health departments, and community healthcare facilities in Indiana.
Represents nearly 99% of non-office care in the state.
Page 10: Data Collected by INPC
Data includes various healthcare events such as:
ED and outpatient visits
Hospital discharges and diagnoses
Laboratory results and imaging reports
Immunizations, operative notes, and medications.
Page 11: Data Organization in INPC
Emphasizes a centralized approach with resources like a global patient index and standardized data structure.
Details about community repositories and separate medical records vaults for participating institutions.
Page 12: Patient Linkage Challenges
The importance of effective patient linkage using various algorithms to minimize false positives while ensuring accurate matching based on identifiable data (name, DOB, SSN).
Page 13: Accomplishing INPC Goals
Emphasizes the community vision, initial grant funding and the importance of legal agreements for operational sustainability.
Page 14: HIE Beyond the U.S.
Discusses HIE implementations in other nations with data showing the impact of access to patients' past medical histories on care quality and efficiency.
Highlights common challenges in accessing health information across borders.
Page 15: Overview of Singapore's National EHR
Describes Singapore's National Electronic Health Record (NEHR) system, which is accessible by healthcare providers and covers longitudinal patient records across institutions.
Page 16: Privacy Concerns with NEHR
Discussion on the ongoing debates surrounding the NEHR's privacy and security measures, especially following breaches.
Page 17: Principles for Implementing HIE
A summary of governance and technical requirements essential to establish a successful HIE framework.
Page 18: Governance Agreements for HIE
Details on tools like Data Use and Reciprocal Support Agreement (DURSA) and Trusted Exchange Framework and Common Agreement (TEFCA) that guide trusted exchanges among health information networks.
Page 19: Technical Requirements for HIE
Overview of the technological infrastructure needed for HIE, including record locator services and federal health architecture tools.
Page 20: Federal Health Architecture Tools
Discusses the role of CONNECT and Direct tools, which are open-source software promoting health information exchange.
Page 21: Commercial HIE Solutions
Highlights tools provided by various vendors, including Epic's Care Everywhere, Carequality, and CommonWell Health Alliance, focusing on interoperability and patient consent management.
Page 22: Additional Commercial Tools
Presentation of services from other vendors like Optum Data Exchange, Surescripts, and the Strategic Health Information Exchange Collaborative (SHIEC).
Page 23: Future of HIE
Poses questions for the future of HIE regarding interoperability from legislative changes, financial sustainability, and data ownership.
