INTRODUCTION

 

Health information sharing has been identified as the key goal for the providers involved in the Panhandle Health Information Exchange project. The partners’ vision is a system that:

 

  • Collects data from multiple sources
  • Is used by providers as the primary source of information at the point of care or service
  • Provides evidence-based decision support
  • Is viable and sustainable
  • Operates within the established networks of rural hospitals, clinics, public health providers, behavioral health providers, and others

 

The partners envision a regional electronic health information exchange system that will enable providers, patients, and others to share information, communicate orders and results, support evidence-based decision-making, streamline public health disease surveillance and reporting, and enable data management for non-clinical purposes (e.g., billing, quality management). Information will be patient-centric (i.e., available where the patient and his/her provider needs it regardless of where the information was originally gathered). Transmission and access of information by authorized individuals will be through secure systems. Technologies and connectivity options will continue to evolve. The partners intend to create a technology that will enable all organizations with basic technological infrastructures to participate.

 

IMPLEMENTATION PROCESS

 

Beginning October 2005, the partnering organizations began moving toward implementation of health information exchange. This project will continue to contribute substantially to achieving an improved, sustainable system of collaborative healthcare that respects the autonomy of hospitals and creates a compatible, shared, unified paperless system that has the capability to seamlessly share patient information among hospitals and providers in real time, which will tie into national standards for integration into national networks.

 

The partners' vision for shared electronic health information has a long-term goal of connecting all health and human services providers and ancillary services in the Panhandle, as well as those that connect to others in the multi-state area, to share patient information and provide a high-quality system of care for rural residents.

 

The goal of this regional partnership of hospitals, behavioral health providers, public health, and health and human services providers is to improve quality of care and patient safety by:

 

  • Enabling the exchange of health information between providers;
  • Contributing to the viability of partners by identifying and promoting collaborative wins;
  • Ensuring that all hospitals and providers have the capacity to participate in electronic exchange;
  • Continuing to promote the vision of a system of care for Panhandle residents;
  • Building capacity within the workforce.

 

The intermediate goal is health information interoperability between hospitals, clinics, private physicians' offices, pharmacies, and behavioral health providers.

 

The short-term goals are to establish:

 

  • Electronic medical records that will integrate with other functional systems (decision support systems, CPOE/e-Prescribing, results management, laboratory) in all Critical Access Hospitals and Rural Health Clinics through a common process and shared resources, in order to enhance local and regional capacity development toward health information exchange.
  • A health information exchange system that will provide current information, from all hospitals and rural health clinics, at the point of care.
  • An operational entity and incorporated RHIO that will provide the sustainable infrastructure necessary to support regional health information exchange and common developments in the Electronic Health Records.

 

PLANNING PROCESS

 

The implementation process is proceeding, based on the yearlong work undertaken from October 2004-September 2005. In September 2005, the partners issued The Panhandle Regional Health Information Exchange Plan. The Plan describes how the partners plan to move forward and also describes the planning process. The Plan may be of particular interest to small hospitals across the nation because it describes the wide variability in technological capacity and readiness represented by the partnering organizations. The Plan focuses on:

 

  • Delineating a standards-based, coherent, scalable and achievable technology solution
  • Articulating the value proposition for individual organizational partners, the critical access network and the regional community
  • Including all hospitals within a regional critical access health network and extend to all health clinic and behavioral health providers
  • Including participation from all levels of leadership from participating partners
  • Working within existing collaborative and information channels to ensure scalability and extensibility to other key health care providers, such as bioterrorism, public health and other safety net providers

 


GLOSSARY

 

AHRQ - Agency for Healthcare Research Quality, a part of the U.S. Department of Health and Human Services.

 

Annual Support and Maintenance - Costs that are typically 15-20% of the software license costs. Where the actual license is normally a one- time fee, the support and maintenance costs are renewed on a yearly basis. This yearly fee basically covers two areas: 1) any upgrades or new releases; and 2) customer service and support. It should be noted that both vendor EHR software and third party software will need support, so it is important to determine which components the support costs cover. Also, some vendors might have more than one service level agreement representing different support options at different costs.

 

Application Service Provider (ASP) - an ASP is a company that creates health (and in many other arenas, as well) information technology solutions available on a subscription basis to health care entities and RHIOS. The ASP distributes the solution from its home central location to customers elsewhere. Thus, an ASP is responsible for maintaining, updating, and troubleshooting solutions (making sure it is available 24/7, ensuring redundancy, etc) that health care entities/RHIOs would otherwise be responsible for doing. ASPs can be an inexpensive way to manage information services.

 

Architecture - “a formal description of an IT system, organized in a way that supports reasoning about the structural properties of the system. It defines the components or building blocks that make up the overall information system, and provides a plan from which products can be procured and systems developed, that will work together to implement the overall system” (Tsiknakis et al., 2002, p. 9). There are three general architectural approaches being used in health information exchange:

 

Centralized architecture is “an approach to RHIO data sharing and inter-change of electronic information emphasizing full control over data sharing through a centralized repository. Components in a centralized architecture refer to the Central Data Repository (CDR) and the requestor. The CDR authenticates the requestor through a technological means, authorizes the transaction and records it for audit and reporting purposes” (HIMSS, n.d.).

 

Federated architecture (decentralized) is an approach to the coordinated sharing and interchange of electronic information emphasizing partial, controlled sharing among autonomous databases within a RHIO. In a federated architecture, independent databases (decentralized) are connected to share and exchange information. Components in a federated architecture represent the various users, applications, workstations, main frames and other stakeholder components in a RHIO. Each component controls its interactions with other components by means of an export schema and an import schema. The export schema specifies the information that a component will share with other components, while the import schema specifies the non-local information that a component wishes to manipulate. The federated architecture provides a means to share data and transactions using messaging services, combine information from several components and coordinate activities among autonomous components. (HIMSS, n.d.)

 

P2P (peer-to-peer): “a network structure in which the computers share processing and storage tasks as equivalent members of the network. Different from a client/server network, in which computers are assigned specific roles…A general term for popular file-sharing systems…in which there is no central repository of files. Instead, files can be stored on—and retrieved from—any user’s computer” (iHealthBeat, n.d.).

 

Audit trail – a chronological record of system activity which enables the reconstruction of information regarding the creation, distribution, modification, and deletion of data.

 

Authentication – a method to verify that the person or entity seeking access to information on a secured Health Information Exchange is the one claimed.

 

Authorization - the role or set of permissions for information system activity assigned to an individual.

 

Best of Breed: The organization buys the best product for a specific function, regardless of how the application interfaces with other applications and systems. This approach often requires expensive integration and support.

 

Best of Fit: Organization limits its selection to products that fit best with existing applications and systems.

 

Best of Suite: A combination of the “Best of Breed” and “Best of Fit.” The organization may use vendor product suites to reduce the number of interfaces needed between numerous systems.

 

Computerized Provider Order Entry (CPOE) - a computer application that allows a physician's orders for diagnostic and treatment services (such as medications, laboratory, and other tests) to be entered electronically instead of being recorded on order sheets or prescription pads.  The computer compares the order against standards for dosing, checks for allergies or interactions with other medications, and warns the physician about potential problems (Office of the National Coordinator for Health Information Technology, n.d.).

 

 

Data Models  - the technical term for the architecture of the data sharing system.

 

Data Ownership – the decisions around who owns shared data and its implications for use.

 

Data Pipes - the actual networks over which data will flow from place to place

 

Data Repository – the database/s that hold patient data

 

Data-Sharing Agreements – executed, formalized documents that define the polices and procedures for data sharing

 

Electronic Health Record – “a subset of each care delivery organization s EMR, presently assumed to be summaries like ASTM s Continuity of Care Record (CCR) or HL7 s Continuity of Care Document (CCD), is owned by the patient and has patient input and access that spans episodes of care across multiple CDOs within a community, region, or state (or in some countries, the entire country). The EHR in the US will ride on the proposed National Health Information Network (NHIN)” (HIMSS Analytics, 2006, pp. 1-2).

 

Electronic Medical Record – “an application environment composed of the clinical data repository, clinical decision support, controlled medical vocabulary, order entry, computerized provider order entry, pharmacy, and clinical documentation applications. This environment supports the patient s electronic medical record across inpatient and outpatient environments, and is used by healthcare practitioners to document, monitor, and manage health care delivery within a care delivery organization (CDO). The data in the EMR is the legal record of what happened to the patient during their encounter at the CDO and is owned by the CDO” (HIMSS Analytics, 2006, p. 1).

 

Electronic Prescribing (e-Prescribing) - provides features to enable secure bidirectional communication of information electronically between practitioners and pharmacies or between practitioner and intended recipient of pharmacy orders. HL7 (2004).

 

Global Patient Index (GPI) - a common medical record number or algorithm that identifies patients across several institutions

 

Health Information Exchange - HIE is “the sharing of clinical and administrative data across the boundaries of health care institutions and other health data repositories” (AHRQ, n.d.)

 

HL7 (http://www.hl7.org) – “an international community of healthcare subject matter experts and information scientists collaborating to create standards for the exchange, management and integration of electronic healthcare information. HL7 promotes the use of such standards within and among healthcare organizations to increase the effectiveness and efficiency of healthcare delivery for the benefit of all” (HL7, n.d.). It is the most widely used messaging standard and includes fields for: diagnostic results, notes, referrals, scheduling information, nursing notes, problems, and clinical trials data.

 

HIPAA - the Health Insurance Portability and Accountability Act of 1996. HIPAA’s Administrative Simplification provisions require the Department of Health and Human Services to establish national standards for electronic health care transactions and national identifiers for providers, health plans, and employers. It also addresses the security and privacy of health data.

 

Information Silos or Stovepipes - proprietary or other disconnected systems that do not exchange information. This often results in multiple entry of information or lack of access to information that others have.

 

Interface Engines - systems that interpret and transform information into structures and representations that make it usable

 

Interoperability - When two or more systems are able to talk to each other and share data

 

Migration Path - high level document tracking all of major projects that move the organization to its goal. The Path plots the journey toward Health Information Exchange and is complemented by, but distinguished from, Readiness Planning, Implementation, Adoption, Benefits realization.

 

National Health Information Network - The collective array of components that underlie nationwide interoperability, such as interconnection tools (mobile authentication, identification management, common web services architecture and security technologies); defined implementation regimens that are specified at the level of software code; common networking and communication tools to unify access and security; and mechanisms for ensuring the sustainable operation of these components on a widespread and publicly available basis must be defined. On November 10, 2005, HHS Secretary Mike Leavitt announced the award of contracts totaling $18.6 million to four groups of health care and health information technology organizations to develop prototypes for a Nationwide Health Information Network architecture.

 

Nebraska Telehealth Network – the interactive videoconferencing that can be used in responding to an emergency and to allow citizens across the state to access health specialists without having to leave their home towns. The Nebraska Statewide Telehealth Network will directly connect 80 Nebraska hospitals, 20 local public health departments, Nebraska's state and regional public health labs, and key state agencies. The goal is to increase the quality, availability, and accessibility of healthcare throughout the state, particularly in rural areas of Nebraska, and to improve the readiness of the state to respond to terrorism-related or public health emergencies.

 

neHII – Nebraska Health Information Initiative. This is an initiative that is exploring whether a statewide RHIO may be established. Partners include the Nebraska Hospital Association, the Nebraska Medical Association, Nebraska Pharmacists Association, Blue Cross/Blue Shield of Nebraska, and a variety of hospitals. Our Panhandle project sits around this table and is represented by Lisa Bewley, Dan Griess, Nancy Shank, Dr. Todd Sorenson, and Kim Woods.

 

Office of the National Coordinator for Health Information Technology (ONC, formerly referred to as ONCHIT) – (http://www.dhhs.gov/healthit/) provides leadership for the development and nationwide implementation of an interoperable health information technology infrastructure to improve the quality and efficiency of health care and the ability of consumers to manage their care and safety. The National Coordinator for Health Information Technology serves as the Secretary's principal advisor on the development, application, and use of health information technology; coordinates the Department of Health and Human Services' health information technology programs; ensures that health information technology policy and programs are coordinated with those of other relevant executive branch agencies; and to the extent permitted by law, develops, maintains, and directs the implementation of a strategic plan to guide the nationwide implementation of interoperable health information technology in both the public and private health care sectors that will reduce medical errors, improve quality, and produce greater value for health care expenditures, and coordinates outreach and consultation by the relevant executive branch agencies with the public and private sectors. The National Coordinator is David J. Brailer, MD, PhD.

 

Outbreak Surveillance - support clinical health state monitoring of aggregate patient data for use in identifying health risks from the environment and/or population (HL7, 2004).

 

PACS - Picture Archiving and Communication System for radiology images.

 

Partners in Panhandle Project - The Regional Health Records for Nebraska's Panhandle project is the collaborative work of the Rural Healthcare Cooperative Network (including Box Butte General Hospital, Alliance; Chadron Community Hospital, Chadron; Garden County Health Services, Oshkosh; Gordon Memorial Hospital, Gordon; Kimball Health Services, Kimball; Memorial Health Center, Sidney; Morrill County Community Hospital, Bridgeport; Perkins County Health Services, Grant; and Regional West Medical Center, Scottsbluff), Panhandle Public Health District, Region I Behavioral Health, Panhandle Community Services Health Center, and the University of Nebraska Public Policy Center.

 

Process Mapping - a technique for making work visible for improvement. It shows who is doing what, with whom, when and for how long. It shows decisions, sequence of events, and any waits times or delays in the process.

 

Record Locator Service - one technical solution to finding the location of patient information

 

RHIO (Regional Health Information Organization) - is a “multi-stakeholder organization that enables the exchange and use of health information, in a secure manner, for the purpose of promoting the improvement of health quality, safety and efficiency. Officials from the U.S. Department of Health and Human Services see RHIOs as the building blocks for the national health information network (NHIN). When complete the NHIN will provide universal access to electronic health records. Experts maintain that RHIOs will help eliminate some administrative costs associated with paper-based patient records, provide quick access to automated test results and offer a consolidated view of a patient’s history” (HIMSS, n.d.).

 

Semantics - provide a way to code message components so their meaning can be interpreted or understood (e.g., which lab tests were performed and what their values are) when the message is deconstructed

 

Standards - the coding and messaging schemes used to share data. Standards apply both to syntax and semantics.

 

Syntax - provides the grammar rules for a defined "language" so that the electronic messages being exchanged can be properly deconstructed when received (AHRQ, n.d.)

 

Use Case Matrixa matrix that identifies which users will use information for what purpose.

 

Work breakdown structure (WBS) – a detailed listing of all tasks for each activity that needs to occur to accomplish a goal.


AGENCY FOR HEALTHCARE RESEARCH AND QUALITY

(http://www.ahrq.gov/)

 

The Agency For Healthcare Research And Quality (AHRQ) is a part of the United States Department of Health and Human Services. AHRQ’s mission is to:

 

improve the quality, safety, efficiency, and effectiveness of health care for all Americans. Information from AHRQ's research helps people make more informed decisions and improve the quality of health care services.

 

AHRQ awarded the Panhandle Regional Health Records project two grants to further our work:

  • Transforming Healthcare Quality Through Health Information Technology Implementation Grant 1 UC1 HS016143-01, $1,498,623, (10/01/05-9/30/08)
  • Transforming Healthcare Quality Through Health Information Technology Planning Grant 1 UC1 HS016143, $198,772, (10/01/04-9/30/05).

 

The AHRQ health information technology portion of the website (http://healthit.ahrq.gov/portal/server.pt?open=512&objID=650&PageID=0&parentname=ObjMgr&parentid=106&mode=2&dummy=/index.html) has lots and lots of information about health information exchange and about other grantees across the United States.


 

 

ARCHITECTURE

 

“Architecture” is defined as the “formal description of an IT system, organized in a way that supports reasoning about the structural properties of the system. It defines the components or building blocks that make up the overall information system, and provides a plan from which products can be procured and systems developed, that will work together to implement the overall system” (Tsiknakis et al., 2002, p. 9).  A “health information exchange architecture” describes the framework for data sharing between healthcare data partners.

 

The architecture should reflect what information which stakeholders want to share. For example, Figure 1 provides an example of a information sharing architecture. This example comes from the Markle Foundation and helps to identify stakeholders and possible information flows between stakeholders, but it does not mandate the technical underpinnings of the system. That is, the information flows in Figure 1 could be implemented through myriad architectural designs.

 

Figure 1. Find, get, send information sharing model from the Markle Foundation (Markle Foundation, 2004, p. 77).

 

 

The components of an HIE architecture include:

Network Connectivity -  The low-level physical connections over which data will flow.

Messaging Standards - Specifications defining consistent message formats and response protocols that ensure accurate data exchange.

Vocabulary Standards – An agreed upon set of unifying codes that uniquely map the same concepts among separate systems into a single code.

Interface Engines - systems that can interpret and translate incoming messages

Record Locator Service - An emerging technology designed to aggregate patient data across large geographical distances or from multiple RHIO’s

Global Patient Index (GPI) – A mechanism for accurately managing patient identities among multiple data sources

Data Sources - the database/s that holds patient data

 

Our project will likely use existing T-1 lines that currently connect the hospitals. Where technically feasible, practical, and applicable we will leverage existing and emerging vocabulary standards, including LOINC® and SNOMED where applicable. Similarly, we will implement clinical messaging standards that are compatible with existing technology, and are flexible enough to accommodate future data sharing needs.

 

There are three general types of HIE architectures:

  • Centralized
  • Federated
  • Peer-to-Peer

 

Most operational HIE’s are not pure representations of a single architecture. Rather, most exchanges blend components of multiple architectures, with one architecture dominating. Because most HIE’s implement a multiple architectures, it is helpful to understand the similarities and differences between the three types.

 

The distinguishing features of these three architectures are characterized by how and where Interface Engines, the Record Locator Service, the Global Patient Index, and the Data Repositories are used.

 

ISSUES TO CONSIDER

 

The architectural model should reflect the needs of the collaboration. Considerations include:

  • Ability to maintain control and ownership of data at each entity
  • Ability to implement its own security policies
  • Ability to observe standards and create local protocols
  • Concern about the security and patient privacy vulnerability in a centralized model

 

CENTRALIZED

Centralized architecture is “an approach to RHIO data sharing and inter-change of electronic information emphasizing full control over data sharing through a centralized repository. Components in a centralized architecture refer to the Central Data Repository (CDR) and the requestor. The CDR authenticates the requestor through a technological means, authorizes the transaction and records it for audit and reporting purposes” (HIMSS, n.d.).

 

The key feature of a centralized system is that all shared patient data from all participating partners is maintained in a single, unified data repository.

 

Interface Engines – either doesn’t exist (in the case where everyone is using the exact same system for electronic health records) or simultaneously interfaces between partners’ systems before transmitting information into the central data repository (and happens prior to any request for patient data).

 

The Record Locator Service and Global Patient Index (GPI) – are essentially the same function. The centralized data repository assigns a patient number that is used when information is matched to patients.

 

Data Repository – a centralized data repository contains all the information that is shared.

 

Examples of Centralized approaches:

Inland Northwest Health Services (www.inhs.org) – partnership of 34 hospitals with over 3000 beds in Washington, Idaho, Montana, Oregon, and Canada that participate in a centralized, integrated information system that shares a single client identifier.

 

FEDERATED

Federated architecture (decentralized) is:

 

an approach to the coordinated sharing and interchange of electronic information emphasizing partial, controlled sharing among autonomous databases within a RHIO. In a federated architecture, independent databases (decentralized) are connected to share and exchange information. Components in a federated architecture represent the various users, applications, workstations, main frames and other stakeholder components in a RHIO. Each component controls its interactions with other components by means of an export schema and an import schema. The export schema specifies the information that a component will share with other components, while the import schema specifies the non-local information that a component wishes to manipulate. The federated architecture provides a means to share data and transactions using messaging services, combine information from several components and coordinate activities among autonomous components (HIMSS, n.d.).

 

Federated systems rely on a decentralized approach to record management, where information is only accessed when needed and clinical data is stored only in the site where created. A distinguishing feature of a federated system is that important technologies, like the Global Patient Index, are centralized, but each institution keeps its own Master Patient Index.

 

Interface Engines – information is translated at the time of it being requested and is aggregated (from a single point that serves all entities) and sent to the inquirer.

 

Record Locator Service – a single Record Locator Service sits at the center of all partners. It uses a type of Global Patient Index (GPI) to match patients.

 

Data Repository – each partner holds its database of patient information.

 

 

Examples of Federated approaches:

HealthBridge (www.healthbridge.org) – provides clinical data exchange among 17 hospitals (in a 14-county tri-state area) and has created a community-wide message platform so physicians and their staff can use one electronic in-box to view radiology, lab, and transcription data, regardless of the organization it originated in. HealthBridge provides a variety of other products and solutions that users may participate in, including electronic chart completion, insurance eligibility checking, on-line referrals, outsourced faxing for physicians who do not wish to use electronic tools, outsourced community printing to share the cost of printing across all hospitals, hospital electronic medical records and administrative tools for hospital and physician offices throughout the Cincinnati area.

 

Indianapolis Network for Patient Care (http://www.inpc.org/) - is a regional computerized patient record system being developed by the Regenstrief Institute, Inc. through a contract with the National Library of Medicine. The INPC was created in 1994 as a a group of federated databases storing emergency room encounter records, hospital abstracts, clinical laboratory data, and other data as available for use by emergency department phycicians. Today it serves 17 hospitals and contains over 900 million discrete records for 2.5 million patients. Some have described the INPC architecture as centralized, but it is actually a federated design. Although all servers are housed and managed at Regenstrief (the partnering hospitals have chosen to use INPC to manage the data), the edge proxies could be housed at each of the partnering hospitals. The data for each institution is physically separate. So if a hospital decided it no longer wished to participate, they could be unplugged from the INPC with no loss of other systems data.

 

 

MAShare (Simplifying Healthcare Among Regional Entities) (www.mahealthdata.org/ma-share/) – established in 2003, to advance the introduction and deployment of clinical data exchange in Massachusetts. The MedsInfo-ED Project is the most complex of MA-SHARE’s initial projects. In 2004, the MedsInfo-ED implemented one of the nation’s first live clinical data exchange initiatives. MedsInfo-ED delivers prescription medication history from disparate data sources to emergency departments MA-SHARE, using the information gleaned from the MedsInfo-ED Project, was able to identify a long-term strategy of creating a Community Utility that offers a portfolio of clinical data exchange services across Massachusetts. These services include: contracting for data access and distribution rights; obtaining consensus regarding privacy and security standards; and developing the clinical data exchange technical infrastructure (MA-SHARE, 2005).

 

Mendocino SHARE (www.ruralcommunityhealth.org/projects/msp.html) - is an alliance of 12 rural partners implementing Health Records Exchange (HRE) using a secure Master Patient Index and Record Locator Service to clinical data available through a secure thin client to diabetes care providers to improve the quality of care for our diabetic patient population. Eventually additional data sources, functionality and user capabilities will be added. Mendocino SHARE's open source solution is being built to developing open standards and the National Health Information Network (NHIN) as described in the new Health IT Strategic Framework from the Office of the National Coordinator for Health Information Technology (ONCHIT). The capabilities underlying the SHARE solution will be available to other communities beyond Mendocino County as free/open source software through OpenHRE.org. Mendocino SHARE is managed by the Alliance for Rural Community Health, and is funded by the Healthy Communities Access Program (HCAP) sponsored by the Bureau of Primary Health Care at the U.S. Department of Health and Human Services.

 

 

PEER-TO-PEER

P2P (peer-to-peer): “A network structure in which the computers share processing and storage tasks as equivalent members of the network. Different from a client/server network, in which computers are assigned specific roles” (iHealthBeat, n.d.).

 

Peer-to-peer is a system in which there is no central repository, instead, files are stored on—and retrieved from—any entities’ systems. The key feature of a peer-to-peer system is that all shared patient data is maintained by partners on their own systems. There is very little of an overarching infrastructure.

Interface Engines – each entity has its own interface engine. The aggregation happens after the appropriate information sources are identified.

 

Record Locator Service – A type of RLS exists between all the peers to assist users to identify the patients and information they want to see aggregated.

 

Global Patient Index (GPI) – may or may not exist in a peer-to-peer system.

 

Data Repository – patient data is held by each partnering organization.

 

 

Examples of Peer-to-Peer approaches:

Santa Barbara County Care Data Exchange (http://www.sbccde.org/) – operates as a public utility and allows patient-specific clinical information to be securely and readily accessible to any authorized person, including the patient.  It serves the County of Santa Barbara using peer-to-peer technology with a central, "smart index" (and a federated data model to access clinical results) from multiple data providers and IT systems within participating healthcare organizations across Santa Barbara County. The system provides secure data access without using a central data repository. Using the system, authorized users within the network can access a "patient-centric" view of clinical and administrative results, including patient demographics, laboratory, pharmacy data, radiology, medical records and transcription, as well as eligibility and referral information.

 

 

 

 

 


HEALTH INFORMATION EXCHANGE

 

The partners have envisioned a system for health information exchange (HIE).  A good definition of HIE is “the sharing of clinical and administrative data across the boundaries of health care institutions and other health data repositories” (AHRQ website, 2006).

 

There are lots of challenges to achieving HIE. Some important issues include:

 

·         Technical - is it possible for the information to be shared (the connectivity, fidelity, and the message structure (the syntax of the information)? When systems are interoperable, it means that they are able to share electronic information in structures that are understandable to other systems.

 

·         Semantic - does the information “make sense” and mean the same thing to the sender as the receiver?

 

·         Social process - have the needed collaborative structures been created so that there is understanding and agreement? Do partners have consensus around issues of data ownership and use, and security practices? How do legal and regulatory issues privacy create barriers?

 

·         Financial – the creation and maintenance of secure systems of exchange require investments that compete with other priorities within organizations, and the financial benefits (reduction in duplicative tests, etc.) often do not accrue to those making the investment.

 

There are many kinds of Health Information Exchange “products.” That is, the kind of information and how the information is used meet different needs. Samarth (2006, pp. 8-17) has provided the following description of Health Information Exchange types:

 

DIFFERENT HIE TYPES TO CONSIDER:

 

1.   Medication History

2.   Web-based Disease Registry

3.   Claims and Eligibility

4.   Referrals Database

5.   Results Repository (lab, rad, etc)

6.   Encounter/Visit History

7.   Patient Health Record

8.   Reporting (Measures, Public Health, etc)

9.   Connecting CHC Data

10. Integration with other RHIOs

 

Need to identify your HIE and then map to feasibility.

 

 

 

1.   Medication History


Description – Provide access to medication history for a patient across provider and care settings.

 

Benefits 

·         Comprehensive view of patient information

·         Prevention of ADEs or complications

·         Better patient education

 

Sources of Data

·         Prescription data from e-Prescribing systems or EMRs


·         Dispensing data from pharmacy records

·         Dispensing data from claims records

·         Dispensing data from PBM pooled data (RxHub)


 

Existing Initiatives

·         Mass Medsinfo-ED Project

o       http://www.mahealthdata.org/ma-share/projects/medsinfo.html

o       Set up 3 or 4 ERs with access to medication records for 4 sites (RxHub, Medicaid Claims, Prescription dispensing) – this information was placed on the internet as a secure stand-alone query application.

o       Lessons learned: need to integrate into clinician workflow, highly regulated meds.

·         Indianapolis – INPC, other repositories

PATIENT MATCHING ACROSS PARTNERING INSTITUTIONS

 

The tools used to match patient data in a health information exchange have a number of names that are used interchangeably such as Global Patient Index, Community Patient Index, Globally Unique Identifier, and Master Patient Index. In our project, we use the term Global Patient Index to differentiate it from an individual partner’s Master Patient Index used by their facility.

 

A Global Patient Index matches information from disparate data sources that relate to an individual patient and creates links between each of these pieces of information to create a set of information for that patient. It does so by collecting patient demographics from all partners and linking them (and their associated Master Patient Index numbers) through a list of lists. The link established by the Global Patient Index between records does use an alphanumeric code, but it is essentially invisible to all users and in no way supersedes or replaces the Master Patient Index number established by any partner.

 

Some implementations of Global Patient Indexes allow some users to create permanent links between information sources when it has been verified that the information represents just one patient. Other Global Patient Index approaches do not make permanent links between organizations’ patient data and instead rely on the user to confirm with the patient.

 

In most cases, users access patient information from the partnering institutions through inputting some or all of patient identifiers such as social security number, patient name, birth date and gender. The Global Patient Index (using algorithms and phonetic transformations) create a possible patient group of those individuals who match or are near matches).

 

There are three general approaches to patient matching (Grannis, n.d.):

           

 

1.      Deterministic – this is the simplest because in order for a provider to get a patient match, all the information must be exactly as the provider inputted it.

a.       All or none

b.      Rules based on exact agreement or disagreement

 

2.      Probablistic – this approach creates customized weights for each of the demographic identifiers.  Instead of requiring an exact match, slight variations are allowed for (and highlighted). For example, information for a patient who has a close, but not exact, date of birth (but, say, not exact because of a number transposition) may also be offered to the provider. The results are often given back to the provider via a scoring system, so that the provider can see how similar or different the patient’s demographic information is. This probabilistic approach is supported by sophisticated algorithms and statistical methods that require fairly high-powered and sophisticated computing systems.

 

3.      Fuzzy Matching – this is a “middle ground,” that uses a combination of deterministic and probabilistic methods. It requires less computing power, since the probabilistic approach does not apply to all patient demographic information.


PROTECTED/SENSITIVE INFORMATION

 

 

Federal and state law protect certain kinds of health information from being shared. The project has received an opinion from Davis Wright Tremaine that responds specifically to related HIPAA and state law barriers regarding general information sharing, alcohol and drug abuse patient information, HIV testing, genetic testing, mental health information, and substance abuse treatment programs/treatment information. Generally, depending on the type of provider and the type of information, there are barriers to sharing these types of protected/sensitive information.

 

Of course, there is concern that not sharing this type of protected/sensitive information compromises providers’ ability to provide quality care. For example, if a patient is on medication for a know protected disease (eg., HIV), this generally would not be shared with other providers. However, if a provider was not aware of the HIV-related medicines, an adverse drug event may result. Most experts seem to agree that a health information exchange cannot imply the existence of missing information without implicitly then disclosing that some protected/sensitive treatments have been received.

 

What are other health information exchanges across the country doing? Everyone is taking a different approach to this.

 

In Tennessee, a disclaimer on their logon screen will remind clinicians that the patient records may not be complete. The disclaimer will be there to remind clinicians that the health information exchange is not their hospital information system, but rather is supplementary data to their hospital’s medical records.

 

Elsewhere, health information exchanges are reminding providers that they have an obligation to confirm with patients the medicine list and query for additional medications. They are educating providers that they must not assume that patient data is the whole picture and must not blindly trust the computer screen, because the health information exchange simply cannot disclose certain types of information (different in each state).

 

Recommended continuing approaches to this are to remind providers that this is improved (but not perfect) information sharing, set reasonable expectations, and provide clear standards and process for patients to consent and opt out of the health information exchange.

 

 

 

 

 

 

 

 

 


STANDARDS

 

Standards are those agreed upon means of structuring and naming information bits. Standards are typically set by industry groups and associations and then adopted by vendors and users.

 

The section below is excerpted from the AHRQ Health Information Technology Portal (http://healthit.ahrq.gov/portal/server.pt?open=514&objID=5554&mode=2&holderDisplayURL=http://prodportallb.ahrq.gov:7087/publishedcontent/publish/communities/k_o/knowledge_library/key_topics/health_briefing_01232006100413/standards.html)

 

 

 

Background

The process of transmitting health information between systems is often referred to as clinical messaging or health data exchange. When multiple information systems can seamlessly exchange messages, they are said to be interoperable.

Standards enable interoperability by encoding health information using a common (generally agreed upon) "language" that multiple systems can read. As an analogy, think about constructing a railway from Boston to Indianapolis. The construction crews in Indiana, Ohio, Pennsylvania, and Massachusetts must lay tracks using the same standard so that the train is not derailed during its journey because the tracks in Ohio are narrower than those in Pennsylvania. Standards in health IT work much the same way - they ensure that test results stored in the lab information system can be safely transmitted from the lab to the patient's electronic health record (EHR) at the hospital or physician office.

There are two broad concepts when talking of standards: syntax and semantics. Syntax provides the grammar rules for a defined "language" so that the electronic messages being exchanged can be properly deconstructed when received. Semantics provide a way to code message components so their meaning can be interpreted or understood (e.g., which lab tests were performed and what their values are) when the message is deconstructed.

Widely Adopted Syntaxes

Widely Adopted Semantics

More on standards, excerpted from Office of the National Coordinator for Health Information Technology (ONC) (http://www.hhs.gov/healthit/standards.html):

 

Standards

Achieving the vision of a national health information infrastructure first requires interoperability to link previously disparate health care information systems. People often confuse interoperability with standards, even though they are different. Standards are much narrower and specify technical details. Interoperability, on the other hand, is a much broader concept that involves both a technical and business context. In the effort to establish this national health information infrastructure, precise interoperability standards for practice must be specified. Below are some efforts across the federal enterprise relating to the issue of standards:

Medical Language - The Department of Health & Human Services (HHS) signed an agreement in 2003 to license a standardized medical vocabulary developed by the College of American Pathologists available for free use in the United States. The College's SNOMED (Systematized Nomenclature of Medicine) Clinical Terms creates a common clinical language that is a necessary element of a health care information infrastructure. Click here to access SNOMED CT online.

Electronic Medical Records - At the request of HHS, the international standards-setting organization known as Health Level 7 (HL-7) has established a tentative standard that defines the set of functions needed in an electronic medical record. HHS continues to work with HL-7 as well as others to define standards for transmitting complete electronic health records.

Consolidated Health Informatics - Along with the Department of Defense and the Department of Veterans Affairs, HHS has worked aggressively to adopt health information standards for use by all federal health agencies. As part of the Consolidated Health Informatics initiative, the agencies have agreed to endorse 20 sets of standards that enable information to be shared across agencies and serve as a model for the private sector.

 
STARK/ANTI-TRUST

 

Quite a number of experts have cited concern about Stark (Fraud & Abuse) and Anti-Kickback laws presenting barriers to health information exchange. An attorney from a large and well-respected law firm (along the lines of Davis, Wright, Tremaine), Pepper Hamilton LLP, provided an excellent overview of what the *proposed* safe harbors proposed by CMS and the Office of the Inspector General (US HHS). The emphasis is on "proposed," because they are not yet law and have no timeframe for becoming law in whatever form they may end up. Thus, it will be difficult for us to plan on relying on them.

 

Currently, Stark II and Federal Anti-Kickback law keep hospitals from providing free/reduced costs hardware and software and other benefits (like training) to doctors. (Some states also have additional self-referral and anti-kickback laws, as well. I've not heard whether Nebraska does or not). So, that's the barrier. What's been done to mitigate the problem? I'll give you an overview and point out where there are still MAJOR, serious problems.

 

1. Medicare Prescription Drug Act of 2003 (also known as the Medicare Modernization Act) had a variety of exceptions to Stark and Anti-Kickback, but they are complex and ambiguous. Plus, many of the monetary value limits are so low ($300!), as to be unusable. No one has been actually attempting to use them.

 

2. In March 2004 CMS issued an interim final rule (effective July 2004) with exceptions under Stark. The "Community-wide health information systems" rule was supposed to have addressed some of the barriers. The problems with this one include:

  • equipment (etc) must be used principally for health exchange (and rarely, in the case of a PC, for example, would this be, or would you want it to be, workflow-wise, the case).
  • the items of value must be available to "all providers, practitioners, and community residents who desire to participate" (!). No one knows what this even means!

The bottom line is this law is also really too ambiguous and no one has attempted to use this exception either. In fact, it was an "interim" rule (suggesting that there was to be a final) but nothing beyond has happened and the new CMS regs aren't really intended to have built upon this one.

 

3. Both the CMS and OIG published proposals on 10/11/05. They are substantially the same and both proposed rules are open for public comment for 60 days.The new rules both address e-Prescribing and EHR separately.

  • e-Prescribing - "Donors" are limited to specific groups (hospitals, PDPs, MA plans, and medical groups). Recipients are limited to physicians and their staffs (Stark) or hospital medical staff, prescribers & pharmacies, and medical group members (Anti-Kickback). Technology may ONLY be used for e-Prescribing (again, not what we would want workflow-wise) and must not be something (or even an upgrade) to something the physician already has.
  • EHR - Stark *prohibits* donation of hardware or equipment. Stark (as it does for e-Prescribing) limits items (other than hardware and equipment, which are already prohibited) to those that are "necessary" and used "solely" for EHR. Anti-Kickback only really outlines issues, but provides very little in the way of substance. The attorney who presented believes that the Anti-Kickback people are leaning toward allowing hardware/equipment, but are considering an extremely low cap on these.

 

In sum, these still fall pretty short from where we want them to be. None of changes permit costs of implementation, support, or maintenance. No post-acute providers are included, either. However, the attorney *believed* (and it would be worth getting another opinion on this, obviously) that a RHIO, or similar 501(c)3 may be in a position to serve as an intermediary donor organization. However, any monetary donations to support this would have to be unrestricted and untargeted. At this point, the law is apparently still murky enough that no hospitals are taking the chance on making donations of any kind. Incidentally, Davis Wright Tremaine also have a nice briefing paper on this at: http://www.dwt.com/practc/healthcr/bulletins/10-05_EPrescribing.htm

 

On a related point, the attorney recommended that RHIOs should err on the side of being very inclusive. Otherwise, there is concern that a RHIO, itself, may violate federal antitrust laws. Evidently, if the benefits of a RHIO are shown to outweigh anticompetitive impact, it would be unlikely that a RHIO would violate federal antitrust laws, but there is some lingering uncertainty.

FREQUENTLY ASKED QUESTIONS

 

1.       Do we all need to use the same EMR product?

 

No! Because we are using standardized information, as long as your EMR product is able to create data according to those standards, it doesn’t matter what EMR you use.

 

Additionally, we will be sharing information beyond what may be in an EMR, so it is possible that even if we were all using the same EMR, there would still be other electronic products (radiology, labs, e-Prescribing, ADT) that will need to tie into our Health Information Exchange.

 

That said, for economies (in technical support and interfaces), we are suggesting that hospital partners choose one of the existing EMRs already in use in the Panhandle.

 

 

 

2.      Would it be better if we all used the same EMR product?

 

Probably not, for several reasons.

 

Different partners have different EMR needs. For example, a hospital will have different EMR needs than a small physician practice.

 

We also intend to build our system so that information may be exchanged (securely, and with proper confidentiality processes) with partners beyond the Panhandle. These partners will, inevitably, be using other products.

 

It may even be a strength that we are using different products. That way we do not become over-reliant (held hostage?) on any single vendor. We will create an environment that allows for market competition.
