Electronic medical record

An electronic medical record (EMR) is a medical record in digital format.

In health informatics an EMR is considered by some to be one of several types of EHRs (electronic health records), but in general usage EMR and EHR are synonymous.

Definition

The term has sometimes included other (HIT, or Health Information Technology) systems which keep track of medical information, such as the practice management system which supports the electronic medical record.

Issues

As of 2006, adoption of EMRs and other health information technology, such as computer physician order entry (CPOE), has been minimal in the United States. Less than 10% of American hospitals have implemented health information technology, while a mere 16% of primary care physicians use EHRs. The vast majority of healthcare transactions in the United States still take place on paper, a system that has remained unchanged since the 1950s. The healthcare industry spends only 2% of gross revenues on HIT, which is meager compared to other information intensive industries such as finance, which spend upwards of 10%. The following issues are behind the slow rate of adoption:

Interoperability

In healthcare, interoperability is the ability of different information technology systems and software applications to communicate, to exchange data accurately, effectively, and consistently, and to use the information that has been exchanged.

In the United States, the development of standards for EMR interoperability is at the forefront of the national health care agenda. EMRs, while an important factor in interoperability, are not a critical first step to sharing data between practicing physicians, pharmacies and hospitals. Many physicians currently have computerized practice management systems that can be used in conjunction with health information exchange (HIE), allowing for first steps in sharing share patient information(lab results, public health reporting) which are necessary for timely, patient-centered and portable care. There are currently multiple competing vendors of EHR systems, each selling a software suite that in many cases is not compatible with those of their competitors. Only counting the outpatient vendors, there are more than 25 major brands currently on the market. In 2004, President Bush created the Office of the National Coordinator for Health Information Technology (ONC), originally headed by David Brailer, in order to address interoperability issues and to establish a National Health Information Network (NHIN). Under the ONC, Regional Health Information Organizations (RHIOs) have been established in many states in order to promote the sharing of health information. Congress is currently working on legislation to increase funding to these and similar programs.

The Center for Information Technology Leadership described four different categories (“levels”) of data structuring at which health care data exchange can take place. While it can be achieved at any level, each has different technical requirements and offers different potential for benefits realization.

The four levels are:

Level Data Type Example
1 Non-electronic data Paper, mail, and phone call.
2 Machine transportable data Fax, email, and unindexed documents.
3 Machine organizable data (structured messages, unstructured content) HL7 messages and indexed (labeled) documents, images, and objects.
4 Machine interpretable data (structured messages, standardized content) Automated transfer from an external lab of coded results into a provider’s EHR. Data can be transmitted (or accessed without transmission) by HIT systems without need for further semantic interpretation or translation.

Older record incorporation

To attain the wide accessibility, efficiency, patient safety and cost savings promised by EMR, older paper medical records ideally should be incorporated into the patient's record. The digital scanning process involved in conversion of these physical records to EMR is an expensive, time-consuming process, which must be done to exacting standards to ensure exact capture of the content. Because many of these records involve extensive handwritten content, some of which may have been generated by different healthcare professionals over the life span of the patient, some of the content is illegible following conversion. The material may exist in any number of formats, sizes, media types and qualities, which further complicates accurate conversion. In addition, the destruction of original healthcare records must be done in a way that ensures that they are completely and confidentially destroyed. Results of scanned records are not always usable; medical surveys found that 22-25% of physicians are much less satisfied with the use of scanned document images than that of regular electronic data.

Privacy

A major concern is adequate confidentiality of the individual records being managed electronically. According to the LA Times, roughly 150 people (from doctors and nurses to technicians and billing clerks) have access to at least part of a patient's records during a hospitalization, and 600,000 payers, providers and other entities that handle providers' billing data have some access. Multiple access points over an open network like the Internet increases possible patient data interception. In the United States, this class of information is referred to as Protected Health Information (PHI) and its management is addressed under the Health Insurance Portability and Accountability Act (HIPAA) as well as many local laws. In the European Union (EU), several Directives of the European Parliament and of the Council protect the processing and free movement of personal data, including for purposes of health care. The organizations and individuals charged with the management of this information are required to ensure adequate protection is provided and that access to the information is only by authorized parties. The growth of EHR creates new issues, since electronic data may be physically much more difficult to secure, as lapses in data security are increasingly being reported. Information security practices have been established for computer networks, but technologies like wireless computer networks offer new challenges as well.

Social and organizational barriers

According to the Agency for Healthcare Research and Quality's National Resource Center for Health Information Technology, EMR implementations follow the 80/20 rule; that is, 80% of the work of implementation must be spent on issues of change management, while only 20% is spent on technical issues related to the technology itself. Such organizational and social issues include restructuring workflows, dealing with physicians' resistance to change (or, alternatively, software engineers' evolving research in deep modeling of the physician's knowledge and workflow domains), as well as IT personnels' resistance to design and implementation flexibility needed in the complex healthcare environment, and creating a collaborative environment that fosters communication between physicians and information technology project managers. Exemplifying this need are several highly publicized HIT implementation failures, such as one at Cedars Sinai Medical Center in Los Angeles, in which physicians revolted and forced the administration to scrap a $34 million CPOE system as well as others compiled at a collection of cases of health IT difficulties by medical informatics specialists. There are, however, several successful examples of EMR implementations in large hospitals, usually hospital systems that have had years of experience developing custom EMRs, for example the Veterans Administration hospital system, Kaiser Permanente's HealthConnect and the VistA EMR.

Technology limitations

Limitations in software, hardware and networking technologies has made EMR difficult to affordably implement in small, budget conscious, multiple location healthcare organizations. Until recently most EMR systems were developed using older programming languages such as Visual Basic and C++; however with many systems now being developed using Microsoft .NET Framework and Java technology EMRs can be securely implemented across multiple locations with greater performance and interoperability. Prior to the recent introduction of IEEE 802.11 g and n wireless technology access to large files such as MRI and X-Ray images was slow. With these new wireless technologies data can be securely transferred at speeds of up to 108 Mbit/s, across extended distances and in older buildings built with brick or concrete walls. Tablet PC technology has significantly improved over the recent years, Li-Ion/polymer batteries for battery life of up to 8 hours, biometric security, low-voltage processors and lighter weight solutions. For the new generation of Tablet PC, there are now EMRs that are fully handwriting capable

Preservation

Under data protection legislation and the law generally responsibility for patient records (irrespective of the form they are kept in) is always on the creator and custodian of the record, usually a health care practice or facility. The physical medical records are the property of the medical provider (or facility) that prepares them. This includes films and tracings from diagnostic imaging procedures such as X-ray, CT, PET, MRI, ultrasound, etc. The patient, however, according to HIPAA, owns the information contained within the record and has a right to view the originals, and to obtain copies under law. Additionally, those responsible for the management of the EMR are responsible to see the hardware, software and media used to manage the information remain usable and not degraded. This requires backup of the data and protection being provided to copies. It will also require the planned periodic migration of information to address concerns of media degradation from use.

Legal status

Medical records, such as physician orders, exam and test reports are legal documents, which must be kept in unaltered form and authenticated by the creator.

  • Digital signatures Most national and international standards accept electronic signatures. According to the American Bar Association, "A signature authenticates a writing by identifying the signer with the signed document. When the signer makes a mark in a distinctive manner, the writing becomes attributable to the signer. With proper security software, electronic authentication is more difficult to falsify than the handwritten doctor's signature. However, as the recent rise in identity theft demonstrates, no security method can totally prevent fraud, so auditing information security will continue to be prudent when using EMR.
  • Digital records such as EHR create difficulties ensuring that the content, context and structure are preserved when the records do not have a physical existence. As of 2006, national and state archives authorities are still developing open, non-proprietary technical standards for electronic records management (ERM).

Standards

Though there are few standards for modern day EMR systems as a whole, there are many standards relating to specific aspects of EHRs and EMRs. These include:

  • ASTM International Continuity of Care Record - a patient health summary standard based upon XML, the CCR can be created, read and interpreted by various EHR or EMR systems, allowing easy interoperability between otherwise disparate enities.
  • ANSI X12 (EDI) - A set of transaction protocols used for transmitting virtually any aspect of patient data. Has become popular in the United States for transmitting billing information, because several of the transactions became required by the Health Insurance Portability and Accountability Act (HIPAA) for transmitting data to Medicare.
  • CEN - CONTSYS (EN 13940), a system of concepts to support continuity of care.
  • CEN - EHRcom (EN 13606), the European standard for the communication of information from EHR systems.
  • CEN - HISA (EN 12967), a services standard for inter-system communication in a clinical information environment.
  • DICOM - a heavily used standard for representing and communicating radiology images and reporting
  • HL7 - HL7 messages are used for interchange between hospital and physician record systems and between EMR systems and practice management systems; HL7 Clinical Document Architecture (CDA) documents are used to communicate documents such as physician notes and other material.
  • ISO - ISO TC 215 has defined the EHR, and also produced a technical specification ISO 18308 describing the requirements for EHR Architectures.
  • openEHR - next generation public specifications and implementations for EHR systems and communication, based on a complete separation of software and clinical models.

Various factors involving the timing, the right players, market history, utility, and governance play a key role in the overall enrichment of the standard and certification development. The standardization and certification even though seem to bring uniformity in the EMR development, do not guarantee their acceptability and sustainability in the long run. In 2005 the US Federal Government awarded a contract to CCHIT - Certification Commission for Healthcare Information Technology to develop certification criteria for EMR. Starting in early 2007 vendors began to utilize these certification criteria for their EMR systems.

Customization

Pricing for EMR systems is highly dependent on each practice's unique needs. Because every medical practice has distinct requirements, systems usually need to be custom tailored. This is due to the majority of EMR systems being based on templates that are initially general in scope. In many cases, these templates can then be customized in co-operation with the vendor/developer to better fit data entry based on a medical specialty, environment or other specified needs. There are also EMR systems available that do not use templates for data entry and therefore can be easily personalized by each individual user. Alternative data entry methods include concept processing, voice recognition, and transcription.

Caveats and concerns

There are issues surrounding the generation and management of electronic medical records (EMRs), sometimes known as electronic health records (EHRs).

There are a two primary categories of the EMR; the "born digital" record and the scanned/imaged record.

The "born digital" record, which is information captured in a native electronic format originally is information that may be entered into a database, transcribed from an electronic tablet or notebook PC, or in some other manner captured from its inception electronically. The information is then transferred to a server or other host environment, where it is stored electronically.

The second category are records originally produced in a paper or other hardcopy form (X-ray film, photographs, etc.) that have been scanned or imaged and converted to a digital form. These records are best described as "digital format records", as their content is not able to be modified or altered (with the exception of the use of a third party software to make "overlay notations") as electronic records are. Most medical records generated preceding the year 2000 are of this category.

The process involved in conversion of these physical records to EMR is an expensive, time-consuming process, which must be done to exacting standards to ensure exact and accurate capture of the content. Because many of these records involve extensive handwritten content, some of which may have been generated by any number of healthcare professionals over the life span of the patient, there exists a high probability of some of the content being illegible following conversion. In addition, the material may exist in any number of formats, sizes, media types and qualities, which further complicates accurate conversion. Consideration should be given to developing a procedure to sample and verify images at a high ratio to determine the accuracy and usability of the scanned images prior to disposal of the physical records, if they are disposed of at all.

Further, all electronic repositories of information are subject to the need for periodic conversion and migration to ensure the formats they were captured in remain accessible over the life of the patient, and in some cases beyond, to the expected life of their heirs. Additionally, those responsible for the management of the EMR are responsible to see the hardware, software (applications) and media used to manage the information remain viable and are not subject to obsolescence or degradation. This will require generation of backup copies of the data and protection being provided to these copies in the event of damage to the primary repository. It will also require the planned periodic migration of information to address concerns of media degradation from use. These are all costly, time consuming processes that must be planned and budgeted for when making decisions to convert physical medical records to digital formats.

Another major concern is adequate protection of privacy of the individuals whose records are being managed electronically. This class of information (in the US) is referred to as Protected Healthcare Information (PHI) and its management is addressed under the Healthcare Insurance Portability and Accountability Act (HIPAA) as well as many State-specific privacy laws. The organization/individuals charged with the management of this information are required to ensure adequate protection is provided and that access to the information is only by authorized parties. Few EMR companies are truly secure and this remains a serious concern. Patientprivacyrights.org is a patient 'privacy' advocacy group that audits EMR companies and rates them for security policies and how well they safeguard patient information. Microsoft Healthvault is one of the first applications to be certified.

Lastly, EMR technology is a new frontier. It has attracted some notoriously unsavory individuals. Some of these companies have been shut down or 'disappeared', but not before extracting a high price from trusting physicians. DrNotes is an infamous example of the worst kind with a very colorful history. Doctorsinperil.org is an organization that helps doctors avoid unscrupulous companies. This organization aggregates complaints against EMR companies, verifies the authenticity and posts the results. Companies with brilliant marketing and polished demos don't necessarily fare well here where endusers speak up and the 'rubber meets the road', so to speak.

Public implementations

As of 2005, one of the largest projects for a national EMR is by the National Health Service (NHS) in the United Kingdom. The goal of the NHS is to have 60,000,000 patients with a centralized electronic medical record by 2010.

The Canadian province of Alberta's Alberta Netcare project is a large-scale operational Electronic Health Record (EHR) system.

Adoption of electronic medical records by US doctors is increasing slowly. The latest data from the National Ambulatory Medical Care Survey (NAMCS) indicate that one-quarter of office-based physicians report using fully or partially electronic medical record systems (EMR) in 2005, a 31% increase from the 18.2 percent reported in the 2001 survey. However, the survey also states that just 9.3% of these physicians actually have a "complete EMR system", with all four basic functions deemed minimally necessary for a full EMR: computerized orders for prescriptions, computerized orders for tests, reporting of test results, and physician notes. Barriers to adopting an EMR system include training, costs and complexity, as well as the lack of a national standard for interoperability among competing software options. Advocates of electronic health records hope that product certification will provide US physicians and hospitals with the assurance they need to justify significant investments in new systems. The Certification Commission for Healthcare Information Technology (CCHIT), a private nonprofit group, was funded in 2005 by the U.S. Department of Health and Human Services to develop a set of standards and certify vendors who meet them. On July 18 2006, CCHIT released its first list of 20 certified ambulatory EMR and EHR products. and then on July 31 2006, additionally announced that two further EMR and EHR products had achieved certification.

In the United States, the Department of Veterans Affairs (VA) has the largest enterprise-wide health information system that includes an electronic medical record, known as the Veterans Health Information Systems and Technology Architecture or VistA. A graphical user interface known as the Computerized Patient Record System (CPRS) allows health care providers to review and update a patient’s electronic medical record at any of the VA's over 1,000 healthcare facilities. CPRS includes the ability to place orders, including medications, special procedures, X-rays, patient care nursing orders, diets, and laboratory tests.
