Automating complex guidelines for chronic disease: lessons learned.

There is scant published experience with implementing complex, multistep computerized practice guidelines for the long-term management of chronic diseases. We have implemented a system for creating, maintaining, and navigating computer-based clinical algorithms integrated with our electronic medical record. This article describes our progress and reports on lessons learned that might guide future work in this field. We discuss issues and obstacles related to choosing and adapting a guideline for electronic implementation, representing and executing the guideline as a computerized algorithm, and integrating it into the clinical workflow of outpatient care. Although obstacles were encountered at each of these steps, the most difficult were related to workflow integration.

Computerized physician order entry systems in hospitals: mandates and incentives.

Concerns with health care quality and medical errors are evident in media reports and research studies. A number of studies have demonstrated that computerized physician order entry (CPOE) can reduce medication error rates. In response, the California government and the Leapfrog Group have called for hospitals to implement CPOE for medications. However, few hospitals now use CPOE. Barriers include the large investment needed and the state of commercial CPOE systems. We argue that government, employers, and insurers should share the costs of CPOE and should fund further research into its benefits and means of implementation.

Overcoming barriers to adopting and implementing computerized physician order entry systems in U.S. hospitals.

Few U.S. hospitals have implemented computerized physician order entry (CPOE) in spite of its effectiveness at preventing serious medication errors. We interviewed senior management at twenty-six hospitals to identify ways to overcome barriers to adopting and implementing CPOE. Within the hospital, strong leadership and high-quality technology were critical. Hospitals that placed a high priority on patient safety could more easily justify the cost of CPOE. Outside the hospital, financial incentives and public pressures encouraged CPOE adoption. Dissemination of data standards would accelerate the maturation of vendors and lower CPOE costs. These findings highlight several policy levers to speed the adoption of this important patient safety technology.

Physicians and ambulatory electronic health records.

Few U.S. physicians use outpatient electronic health records (EHRs), although it appears that most would like to begin. The main barriers are not technical, because adoption rates in other countries are high. The biggest barrier is reimbursement, because physicians must pay for EHRs, but most of the benefits accrue to payers and purchasers. The lack of interoperability is also pivotal. Others include capital and risk tolerance; physicians' resistance related to time concerns, fears about privacy, system maintenance, the number of vendors in the marketplace, and the transience of vendors. The key initial policy changes will be those addressing financial incentives and interoperability.

Functional gaps in attaining a national health information network.

We describe the health information technology (HIT) required for a model of a national health information network (NHIN). Specifically, we define the functional HIT capabilities of an attainable NHIN and determine the gap between the current state of HIT and its likely state in five years, given current trends of adoption. Administrative functionalities will be more prevalent than clinical functionalities in five years. Smaller stakeholders, such as home health care agencies, will lag in adoption. Policy changes, such as financial incentives to HIT end users or regulatory measures, may help accelerate the adoption of HIT for a model NHIN.

The value of health care information exchange and interoperability.

In this paper we assess the value of electronic health care information exchange and interoperability (HIEI) between providers (hospitals and medical group practices) and independent laboratories, radiology centers, pharmacies, payers, public health departments, and other providers. We have created an HIEI taxonomy and combined published evidence with expert opinion in a cost-benefit model. Fully standardized HIEI could yield a net value of dollar 77.8 billion per year once fully implemented. Nonstandardized HIEI offers smaller positive financial returns. The clinical impact of HIEI for which quantitative estimates cannot yet be made would likely add further value. A compelling business case exists for national implementation of fully standardized HIEI.
