Section snippets
Foreword
In October 2013, the American College of Emergency Physicians (ACEP) Council adopted Resolution 29(13): Support of Health Information Exchanges:
- •
Resolved: that ACEP investigate and support health information exchanges
- •
Resolved: that ACEP work with appropriate stakeholders to promote the development, implementation, and use of a national health information exchange
- •
Resolved: that ACEP develop an information article exploring a national health information exchange
A workgroup was created to
Definitions
The Department of Health and Human Services current definition states that “Health Information Exchange is the electronic movement of health-related information among organizations according to nationally recognized standards. The goal of health information exchange is to facilitate access to and retrieval of clinical data to provide safer, timelier, efficient, effective, equitable, patient-centered care.”3
The terms regional health information organization and health information exchange are
Background and History
Health information exchange has been a key goal of health care since the advent of the modern computer. Limited, closed exchange networks, primarily for research purposes, emerged in the late 1980s. But it was the propagation of the Internet in the early 1990s that enabled technology to extend exchange beyond institutional walls.
The 1990s saw the emergence of community health management information systems funded by grants from the Hartford Foundation to 7 states and cities to implement large
Patient Crossover
Patients often move among providers and hospitals, with significant patient crossover rates in emergency medicine. One study showed that 25% of patients with more than 1 ED visit during a 1-year study period used more than 1 hospital, and those visits composed 19% of all ED visits.11 A similar, more recent study showed that 40% of patients with ED visits during a 3-year study period had data at multiple institutions.12 Another study of all visit types found that 41% of patients had visits at
Health Information Exchange Marketplace
The current health information exchange market can be divided into 2 distinct sectors, each with its own unique needs and requirements:
- 1.
Public health information exchanges, often funded by federal, state, and local governments, typically provide health information exchange services across a geographic region or state. Many have struggled to define a sustainable business model and wean themselves from diminishing grant-based start-up funds. This has created a “churn and burn” phenomenon among
Different Types of Health Information Exchange
According to the Office of the National Coordinator for Health Information Technology, currently there are 3 key forms of health information exchange.45 Although query-based exchange is the form that is most often used in emergency medicine and is the primary focus of this article, a brief review of each follows:
- 1.
Query-based exchange is used by providers to search for and discover clinical data sources from outside the treating provider’s practice environment for a particular patient. This type
Architectural Overview
Health information exchanges generally fall into one of 3 basic architectures: The centralized model uses a monolithic database that includes data from all stakeholder organizations. The federated model allows each stakeholder organization to maintain either physical or virtual “edge” servers, allowing them to maintain stewardship over the data they contribute. With a federated architecture, each edge server contains a common data structure, and the network of edge servers functions as a
Technical Overview
The elements described below are integral parts of most health information exchange implementations:
Competitive Concerns
Although ownership of health data is often debated,53 many provider organizations consider their stewardship and control of the patient data they generate to be a business asset and may be reluctant to share data with competitors. Provider organizations may be concerned that if data flow freely, patients may have less reason to remain loyal, or that data might be used by competitors to create a strategic market advantage. It has been historically difficult to promote health information exchange
Recommendations
Significant changes in practice and public policies are necessary to support a system of effective national health information exchange that can rapidly and efficiently yield useful health information to clinicians, especially in the emergency care setting. These changes should include support for emergency clinician access to all relevant patient information, in properly summarized understandable form to provide safe, efficient, and effective emergency care. Below we list 5 primary
