In a 2008 study about the adoption of technology in the United States, Furukawa and colleagues classified applications for prescribing to include
electronic medical records (EMR),
clinical decision support (CDS), and
computerized physician order entry (CPOE). They further defined applications for dispensing to include bar-coding at medication dispensing (BarD), robot for medication dispensing (ROBOT), and
automated dispensing machines (ADM). They defined applications for administration to include electronic
medication administration records (eMAR) and
bar-coding at medication administration (BarA or BCMA). Other types include
Health information exchange.
Electronic health record (EHR) Although the electronic health record (EHR), previously known as the electronic medical record (EMR), is frequently cited in the literature, there is no consensus about the definition. However, there is consensus that EMRs can reduce several types of errors, including those related to prescription drugs, to preventive care, and to tests and procedures. Recurring alerts remind clinicians of intervals for preventive care and track referrals and test results. Clinical guidelines for disease management have a demonstrated benefit when accessible within the electronic record during the process of treating the patient. Advances in
health informatics and widespread adoption of interoperable electronic health records promise access to a patient's records at any health care site. A 2005 report noted that medical practices in the United States are encountering barriers to adopting an EHR system, such as training, costs and complexity, but the adoption rate continues to rise (see chart to right). Since 2002, the
National Health Service of the United Kingdom has placed emphasis on introducing computers into healthcare. As of 2005, one of the largest projects for a national EHR 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 health record by 2010. The plan involves a gradual roll-out commencing May 2006, providing
general practices in England access to the
National Programme for IT (NPfIT), the NHS component of which is known as the "Connecting for Health Programme". However, recent surveys have shown physicians' deficiencies in understanding the patient safety features of the NPfIT-approved software. A main problem in HIT adoption is mainly seen by physicians, an important stakeholder to the process of EHR. The Thorn et al. article, elicited that emergency physicians noticed that
health information exchange disrupted workflow and was less desirable to use, even though the main goal of EHR is improving coordination of care. The problem was seen that exchanges did not address the needs of end users, e.g., simplicity, user-friendly interface, and speed of systems. The same finding was seen in an earlier article with the focus on
CPOE and physician resistance to its use, Bhattacherjee et al. One opportunity for EHRs is to utilize
natural language processing for searches. One systematic review of the literature found that searching and analyzing notes and text that would otherwise be inaccessible for review could be accessed through increasing collaboration between software developers and end-users of natural language processing tools within EHRs.
Clinical point of care technology Computerized provider (physician) order entry Prescribing errors are the largest identified source of preventable errors in hospitals. A 2006 report by the Institute of Medicine estimated that a hospitalized patient is exposed to a medication error each day of his or her stay. Computerized provider order entry (CPOE), also called computerized physician order entry, can reduce total medication error rates by 80%, and adverse (serious with harm to patient) errors by 55%. A 2004 survey by found that 16% of US clinics, hospitals and medical practices are expected to be utilizing CPOE within 2 years. In addition to electronic prescribing, a standardized
bar code system for dispensing drugs could prevent a quarter of drug errors. Such concerns are not inconsequential; standards for
electronic prescribing for
Medicare Part D conflict with regulations in many US states. ==Technological innovations, opportunities, and challenges==
