| Internet-based educational approaches can facilitate participation in CME programs |
|---|
|
|
|---|
As Internet use by physicians has increased dramatically, it has been suggested that some of the challenges providers and consumers of CME face could be ameliorated by shifting to web-based educational materials. Meanwhile, there has been explosive growth in both traditional and online CME offerings. According to Bernard Sklar, a physician who has followed online CME trends, there were 150 CME websites offering 3,510 activities for 5,500 credit hours in December 2000. By June 2002, there were 209 sites offering 10,952 activities and 18,263 credit hours (2). Despite this dramatic growth in providers and offerings, however, online CME credits still constitute a small fraction of total CME credits awarded. According to a 2001 survey by the Boston Consulting Group, physicians are changing their online information-seeking practices. Doctors appear to be reducing the number of sites they use for medical information, and professional association sites such as the ACC's Cardiosource (www.cardiosource.com) are showing the greatest gains in use (3).
Online CME use by physicians will continue to grow as concerns and issues raised by CME consumers are addressed:
"Just in time" education to meet the needs of practitioners providing care to patients. It is believed that the most "teachable moment" occurs when a medical student, resident or practicing physician is actively engaged in the care of a specific patient. Information obtained in that setting is more likely to be remembered and to have a lasting impact on practice behavior. As providers gravitate toward electronic medical record (EMR) systems and computers become even more common in the hospital and office settings, the likelihood increases that physicians will have (or will demand) more access to so-called "just-in-time" learning (i.e., CME that occurs in real-time in the context of patient care). Applications that focus on this type of context-based learning are being developed. Meanwhile, evidence-based practice databases are being imbedded in various types of EMR products, such as physician order-entry and standardized order sets.
An example of "contextual" online medical information and CME is the Stanford SKOLAR MD program. Subscribers can access a number of medical reference books, full-text journals, drug databases, practice guidelines, evidence-based medicine resources and patient educational material. They can also receive Category-I credit for conducting a search and answering online questions regarding the material. It seems likely that this type of "granular CME" has the potential to increase the efficiency of obtaining CME credit and to reward physicians for using information resources while taking care of patients.
Meanwhile, trends in consumer education are affecting the content and context of communications between patients and their physicians. Many patients now use the Internet to gain insights into their health problems and treatment alternatives. Already, consumers use the Internet to obtain health information more than for any other reason (4). More people go online daily to look up health care information (6 million) than visit doctors. In 2000, the Pew Internet and American Life Project reported that 52 million Americans relied on the Internet to make crucial health care decisions; in 2002 that number increased to 73 million.
The growth and impact of direct to consumer advertising in recent years has also been dramatic. Despite these trends, many patients still prefer to receive health information directly from their physician or a member of his or her staff. One concern about patients using the Internet to seek health information relates to the reliability of what they find and read. To help physicians direct their patients to reliable health information on the Internet, the National Library of Medicine (NLM) and the American College of Physicians (ACP) are piloting an "information prescription" program. This allows a physician to provide a patient with a pre-designed prescription that takes him or her directly to high-quality health information on Medline Plus. Similar partnerships, designed more specifically for cardiologists and patients with cardiovascular disease, may be possible for the ACC.
Point-of-care education and advice via wireless devices. The growing use of personal digital assistants (PDA) by physicians represents another opportunity for point-of-care education and interactivity. A 2002 ACC survey found that 54% of members reported using a PDA for one or more professional functions. The scope and sophistication of clinical and professional applications designed for PDAs continue to increase dramatically. The case of the free drug database application, ePocrates Rx, is instructive. This application (used by more than 100,000 health professionals) was the subject of a recent survey reported by Bates and colleagues at the Brigham and Women's Hospital in Boston (5). They surveyed a random sample of 3,000 ePocrates Rx users; 32% responded. Users identified several advantages of this program, including saving time during information retrieval, ease of incorporation into patient workflow, and enhanced decision making in drug selection and dosing. Respondents also believed their use of the database reduced preventable adverse drug events. Systems that will document the use of PDA resources as a way to receive CME credit will likely be developed. The convergence of PDAs and bar code technologies in the healthcare industry will provide opportunities to link specific information searches (e.g., guidelines) to specific patient evaluations in a way that can be used to document an individual physician's attempts to provide high-quality care.
| Electronic communication between patients and physicians |

The impact of e-communication will vary depending on the balance between health care practitioners "pushing" information to patients and patients/consumers demanding or "pulling" information from health care providers (6). Kaiser, the large California HMO, has a members-only consumer website designed to give members an alternative to calling or visiting their physician or other health care provider. The service includes health-learning materials, health assessment tools, and links to selected health-related sites. Patients can also communicate with other members, Kaiser staff, and physicians.
Although e-mail is now the preferred method of communication among friends, family members, and colleagues, anecdotal information suggests that physicians are reluctant to use e-mail for patient correspondence because they are concerned about the volume of messages they may receive from patients or concerned family members. Moreover, there is no reimbursement for e-mail (or telephone or written) advice. Still, using e-mail to answer patient questions and/or to provide educational materials could reduce the amount of "communication time" with patients, as direct telephone conversation may be lengthy compared with more succinct replies via e-mail. Written messages to patients could enhance the ability of patients to follow instructions.
Tools that provide information that supports self-care and decision making by patients may ultimately reduce demand for unnecessary services (7). For a significant transition from face-to-face visits to online communication between physicians and patients to occur, however, reasonable reimbursement for the services provided electronically must be established. Recently, Blue Shield of California made a decision to reimburse physicians for time spent providing online consultations for patients via e-mail (8).
Another approach used by some medical practices is to establish a Website with a secure connection for health care providers and patients. The VeriSign Secure Site, or similar programs that employ security measures akin to those used by banking and e-commerce sites on the Internet, enhance the privacy of submitted information. The establishment of such a secure site is likely to be cost-effective for many practices that want to communicate with patients in a secure fashion. This may reduce costs and increase convenience because a patient can receive information from his or her physician about test results, treatment options, and prescriptions without actually visiting the doctor's office. In contrast to e-mail, this form of secure e-communications addresses privacy issues that are of such concern in contemporary medical practice. There are many potential uses for and advantages of such a system for patients as well as physicians and members of their staff. These include:
| The electronic medical record (EMR) |

The EMR is considered to be an essential tool to improve health care efficiency and enhance outcomes. Nevertheless, obstacles such as cost and resistance to change have delayed its widespread adoption (12). A recent survey of 1,587 physician organizations showed that clinical use of information technology (IT) systems for electronic data capture was inconsistent (13). When asked if their electronic data system included a standardized problem list, progress notes, medications prescribed, medication decision support, laboratory results, and radiology results, the average physician organization had only 1.4 (23%) of these six capabilities; 49.9% had none and 78.5% had two or less. For the immediate future, partial integration of EMR systems is likely to limit the attainment of potential efficiencies on physician workflow. Utilization of EMRs in health care will be imperative to consolidate patient data efficiently and to optimize the display of relevant clinical information used to make medical management decisions. After a steep learning curve, the EMR should improve overall productivity and practice efficiency.
The ability to enter relevant patient care information at the bedside quickly and accurately should enhance patient care and improve outcomes. Physicians and other providers can become more efficient if they can enter or access data at several convenient locations in the hospital or outpatient setting. Key findings and progress notes can be entered at the point of care and transferred to the hospital record and/or a provider's EMR through a wireless network. Palmtops and PDAs are being used increasingly as a point-of-care tool. Software applications that are particularly useful to physicians include patient tracking, laboratory order entry and results checking, medical calculations, prescription writing, and charge capture (14). Providers can also monitor real-time data via a Web browser or wireless application (15). Potential efficiencies include the avoidance of duplicative efforts, enhanced decision making, and reduction in workload for physicians, non-physician clinicians, and other personnel. Problems with legibility of progress notes would be eliminated, reducing potential errors and saving time for other medical personnel involved in the patient's care.
Point-of-care technology includes the use of palmtops not only to retrieve patient clinical data, but also to retrieve important scientific information useful in patient care and decision making. As mentioned earlier, ePocrates is an example of medication software that provides ready access to information on cost, dosing, drug interactions, and adverse reactions (16). A survey of physicians using ePocrates Rx revealed that this tool facilitated information retrieval, was easily incorporated into the workflow, and improved the quality of decision making (5). Although many physicians use PDAs, only 4% were estimated to use them for writing prescriptions (17). It is likely that electronic prescription "writing" will replace the traditional handwritten prescription because it can facilitate documentation and communication and reduce errors (18). Barriers must be overcome to encourage the widespread utilization of these tools. A 2001 Harris Poll showed that 26% of physicians used PDAs, but this number is expected to double by 2005 (19).
Computerized physician order entry (CPOE) has also been demonstrated to improve quality and reduce resource utilization; but many studies suggest it takes longer to enter orders (20). One study showed that physicians in training spent 9% of their time on CPOE functions compared with 2% with paper order entry. Some of the increased time spent on CPOE can be counterbalanced by decreased time used by other personnel such as pharmacists and nurses.
Rapid electronic retrieval of laboratory, pathology, and radiology reports. The ability to retrieve clinical information promptly plays an integral role in optimizing decision making and providing quality care. The near instantaneous electronic acquisition and/or display of data at the physician's fingertips can substantially reduce the time of an office visit. Commercially available computer systems make it possible to view pathology specimens, radiology films, and other imaging studies from any computer workstation in a hospital or other integrated practice location. This eliminates the need to visit the laboratory or X-ray department to view studies, which, in turn, should increase the likelihood that the ordering physician will review the actual images rather than rely entirely on written or verbal reports.
In a study of so-called picture archiving and communication systems (PACS), referring physicians unanimously preferred PACS over film, and 91% of users believed they increased their productivity (21). Integration of a PACS into an EMR maximizes efficiencies in the system (22). Extending the ability to view imaging tests electronically to a physician's office can further enhance efficiency and productivity. Remote viewing of imaging studies also makes it possible to show patients and family members the actual echocardiogram or angiogram images used to make treatment decisions.
| Electronically provided "disease management" guidelines |

A recent physician survey showed that 68% had received guidelines from health plans and 57% had access to disease management (DM) programs (26). Eighty-five percent of generalists and 71% of specialists found clinical guidelines useful; 83% of generalists and 74% of specialists found DM programs useful. By enhancing quality of care through better adherence to guideline recommendations, it is also possible that reductions in health care utilization might occur, thereby reducing unnecessary scheduled patient visits, phone calls, and hospitalizations.
| Telemedicine potential |
|---|
|
|

In the "store-and-forward" approach, clinical images (e.g., information derived from an examination or a procedure) are sent to another site for display, interpretation, and permanent storage. The advantage of the store-and-forward technology is that it obviates the need for simultaneous availability of the consulting parties. The low bandwidth requirements for this technique also make it less expensive. The store-and-forward format is appropriate when a formal report is not required for immediate decision making. A much more demanding telemedicine approach is the "real-time" transfer of an examination record so that two (or more) caregivers (and a patient) in different locations can simultaneously assess the results provided by the imaging examination. Logistical issues such as scheduling all the parties at the same time and accessing bandwidth on demand have limited the use of real-time telemedicine.
Meanwhile, development of the Digital Imaging and Communication in Medicine (DICOM) led to the acceptance of a standardized format and media (CD-ROM) for archiving, exchanging, and transferring images. The acceptance of the DICOM standard means that coronary angiograms can be viewed in different institutions and over time (facilitating comparison with prior studies). With the availability of the standardized DICOM format, in addition to the image acquired at the site of procedure (e.g., a community hospital) the images can be displayed at a remote site (e.g., a tertiary referral center). In interventional cardiology, for example, this approach is an excellent tool for education and practice.
In contemporary cardiology practice the most common application of telemedicine is the transmission of electrocardiograms. It has been shown to be especially effective in pediatric cardiology, where the prompt and accurate diagnosis of congenital heart disease in the neonate may be crucial to the outcome of the patient (27,28). One benefit of the telemedicine link is to be able to provide a remote diagnosis from transmitted images to help decide whether and when patient transfer is indicated. Telemedicine can enhance patient care and inform decisions with respect to the need to transfer patients from community hospitals to referral centers.
The use of telemedicine in the catheterization laboratory is still in its infancy. There are four important areas of potential application for real-time catheterization procedure data transfer: 1) physician training, 2) clinical conferencing, 3) support for clinical trials, and 4) support for clinical procedures. Except for clinical conferencing, the other applications require accurate replication of angiographic, echocardiographic, and intravascular sound data. This would require high-fidelity, and higher bandwidth telecommunications systems. The cost of such systems may preclude the routine use of telemedicine in cardiology at the present time. Telemedicine holds much promise for cardiology practice, but some important issues need to be resolved (e.g., reimbursement, licensure, and HIPPA) before it can achieve its full potential.
