The coming before chapter describes an array of systems-engineering tools and associated techniques for analyzing, designing, controlling, and also improving health care delivery processes and systems. This thing is concentrated on the applications of information and communications modern technologies to the distribution of safe, effective, timely, patient-centered, efficient, and equitable health and wellness care, a review of progression toward the establishment of a National health Information framework (NHII), and a summary of the work that lie ahead. The committee highlights the complementary nature of information/ communications technologies and systems engineering.


Information and information exchange are crucial to the shipment of care on all levels the the health care delivery system—the patient, the care team, the health care organization, and also the encompassing political-economic environment. Come diagnose and also treat individual patient effectively, individual treatment providers and care teams must have accessibility to at the very least three major types of clinical information—the patient"s health and wellness record, the rapidly changing medical-evidence base, and also provider assignment guiding the procedure of patient care. In addition, lock need info on patient preferences and values and also important bureaucratic information, such as the standing and accessibility of supporting resources (personnel, hospital beds, etc.).

To combine these vital information streams, lock will additionally need training/education, decision-support, information-management, and also communications tools. Because that individual patient to get involved as informed, “controlling” partner in the style and management of their very own care, lock must also have access to much the exact same kind of information and also education, decision-support, and communications tools—in a “patient-accessible/usable” form.

At the business level, hospitals and also clinics require clinical, financial, and administrative data/information come measure, assess, control, and also improve the quality and also productivity of your operations. At the eco-friendly level, federal/state funding and regulatory agencies and also research establishments need details on the wellness status the populations and the quality and also productivity/performance of treatment providers and organizations come execute regulation oversight, defend and advance the public wellness (surveillance/monitoring), evaluate brand-new forms that care, accelerate research, and disseminate new medical knowledge/evidence.

As discussed in chapter 3, information and also information exchange space also an important to the tactical and strategic applications that systems-engineering tools at all four levels that the system, especially for strategic applications that enterprise-management tools and also risk analysis and administration tools in ~ the organizational and also environmental levels.

The Information an innovation Deficit and also Its Proximate Causes

Although details gathering, processing, communication, and management are crucial to health care delivery, the health treatment sector together a whole has in the history trailed far behind most other sectors in investments in information/ communications technologies (DOC, 1999). Moreover, most health and wellness care-related information/communications modern technologies investments to date have been concentrated on the governmental side of the business, fairly than on clinical care. As a result of this lengthy underinvestment, tiny overall progress has been made toward meeting the info needs that patients, providers, hospitals, clinics, and also the broad regulatory, financial, and research environment in which lock operate. A variety of localized initiatives have been made to develop and also implement electronic patient records and also other clinical applications that information/communications technologies since the 1960s, but small progress has actually been made in closing the gap.

Many factors have contributed to the information/ communications an innovation deficit: (1) the atomistic framework of the industry (the ubiquity of reasonably undercapitalized tiny businesses/provider groups); (2) payment/reimbursement regimes and the lack of transparency in the sector for health treatment services, both the which have discouraged private-sector investment in information/communications systems; (3) historical weaknesses in the managerial society for wellness care; (4) cultural and organizational barriers related come the ordered nature and also rigid division of labor in health and wellness professions; and also (5) the family member technical/functional immaturity (until very recently) of easily accessible commercial clinical information/communications systems.


The idea that transforming file medical documents into digital medical documents (EMRs) was very first considered in the mid-1960s, when early prototype solution were developed. A number of big integrated health care provider organizations were at an early stage adopters the EMR systems, consisting of Massachusetts general Hospital (COSTAR) in the 1960s, Indiana University clinical School (Regenstrief clinical Record System) in the beforehand 1970s, and also others (Kass-Bartelmes et al., 2002; Lindberg, 1979). However, over there was tiny diffusion that these equipment in the following two decades. In 1991 and 1997, IOM approve reports documenting the magnitude and also implications that the large information-technology gap in U.S. Health and wellness care and called for the fostering of EMRs together a first, critical step in relocating health treatment delivery toward information/communications-technology-supported renovations in high quality performance achieved in other sectors (IOM, 1991, 1997).

Building on this studies, a collection of reports by IOM, the national Committee on crucial and health and wellness Statistics (NCVHS), and also other organizations in the past 5 years have recorded the profound an adverse impact of the information/ communications modern technology deficit on patient safety, the variety of medical errors, and also the quality and cost of care; every among these reports calls for the advance of a substantial health care information framework (e.g., NHII) to help close the gap (IOM, 2000, 2001, 2003, 2004; NCHVS, 2001; NRC, 2000).

In information for Health: A Strategy for structure the National health and wellness Information Infrastructure, NCVHS described the NHII as both infrastructure and a defined collection of components linked explicitly come health care delivery procedures (NCVHS, 2001). IOM (2004) summarized the NCVHS meaning as follows:

The NHII is identified as “a set of technologies, standards, applications, systems, values, and also laws that assistance all facets of separation, personal, instance health, health care, and also public health”… It includes an information network based on Internet protocols, typical standards, timely knowledge transfer, and transparent government processes through the ability for details flows across three dimensions: (1) personal health, to support people in their own wellness and also health treatment decision making; (2) health care providers, come ensure access to complete and also accurate patient data around the clock and also to clinical decision support systems; and also (3) public health, to deal with and monitor public health concerns and also health education campaigns.

This present of reports native IOM, NCVHS, and others catalyzed a variety of actions in the private and also public sectors intended come lay the groundwork for and build momentum toward realization that the NHII (IOM, 2004; PITAC, 2004; Thompson and also Brailer, 2004; Yasnoff et al., 2004). Influenced by the 1999 IOM report, come Err Is Human, the Leapfrog group for patient Safety, a coalition of big companies developed expressly for the purpose of using their sector power as significant purchasers that health treatment to encourage treatment providers to improve the safety, quality, and efficiency of health care. The Leapfrog Group called on all health care provider institutions serving Leapfrog members" employees to use information/communications equipment (EMRs and also computerized doctor order entry equipment in particular) (see document by Milstein in this volume).

In April 2004, progress toward an NHII was given new impetus once President shrub called for national implementation of EMRs and also announced the creation of the Office the the national Coordinator for health Information an innovation (ONCHIT) in the U.S. Department of Health and also Human services (DHHS); Dr. David Brailer to be appointed the an initial national coordinator. In July, DHHS exit a report outlining a 10-year arrangement to build an NHII, consisting of the production of electronic health records (EHRs), for every Americans (Thompson and also Brailer, 2004). In November 2004, ONCHIT approve a inquiry for info (RFI) because that a National health and wellness Information Network (NHIN), soliciting suggest for methods to development interoperability and standards. Together of early on 2005, ONCHIT had actually received much more than 500 responses indigenous a wide variety of organizations and also collaboratives.

One of the respondent to the RFI, the Interoperability Consortium, an alliance of eight information-technology systems merchants (Accenture, Cisco, CSC, Hewlett-Packard, IBM, Intel, Microsoft, and Oracle), explains the current difficulties to interoperability:

Dozens of communities and also innovative networks throughout America have started implementing details exchange solutions—yet castle are following no usual pathway, no uniform standards, and have established no basis for eventual information exchange amongst them or with the crucial national information networks currently in existence. A typical framework is needed to guide and also maximize the value of the enthusiastic efforts currently in the field.

In that is preliminary blueprint for NHIN, the Interoperability Consortium (2005) stresses the the NHIN must be component of one agenda for the comprehensive change of health care delivery:

The NHIN should be approached together an IT-enabled clinical change initiative the fuses modern technology and procedure reengineering in bespeak to attain its proclaimed objectives of boosting quality and decreasing costs. Performance metrics need to be developed to screen progress, and also incentives must be to adjust (and regularly adjusted) come reward actual benefit realization. Whereas the expenses attached to supporting and also monitoring the efficiency of this transformation agenda need to be had in the NHIN"s full cost that ownership.

To accomplish these requirements, the NHII/NHIN need to be a secure, reliable, and adaptable nationwide infrastructure qualified of connecting and also supporting very distributed, varied, separately managed, multi-tiered, intra-institutional, clinical information/communications modern technology systems and also applications. This framework would vastly increase the info gathering, exchange, processing, and also application capability of stakeholders in ~ all 4 levels the the health treatment system.
