A document processing architecture for electronic medical records.

An Electronic Medical Record System (EMRS) requires a deep analysis of the clinical workplace and of the character and uses of the medical record itself. Charts are a diverse and useful collection of loosely structured specialized documents, each with an orderly outline, but widely divergent and unpredictable contents--the more critical the case, the more unpredictable the details. This can be achieved by adapting an underlying information architecture that is based on document processing (rather than data processing), using the logic and conventions of text tagging, as in Mosaic, the Standard Generalized Markup Language (SGML), and HyTime.

Evidence for handheld electronic medical records in improving care: a systematic review.

BACKGROUND: Handheld electronic medical records are expected to improve physician performance and patient care. To confirm this, we performed a systematic review of the evidence assessing the effects of handheld electronic medical records on clinical care. METHODS: To conduct the systematic review, we searched MEDLINE, EMBASE, CINAHL, and the Cochrane library from 1966 through September 2005. We included randomized controlled trials that evaluated effects on practitioner performance or patient outcomes of handheld electronic medical records compared to either paper medical records or desktop electronic medical records. Two reviewers independently reviewed citations, assessed full text articles and abstracted data from the studies. RESULTS: Two studies met our inclusion criteria. No other randomized controlled studies or non-randomized controlled trials were found that met our inclusion criteria. Both studies were methodologically strong. The studies examined changes in documentation in orthopedic patients with handheld electronic medical records compared to paper charts, and both found an increase in documentation. Other effects noted with handheld electronic medical records were an increase in time to document and an increase in wrong or redundant diagnoses. CONCLUSION: Handheld electronic medical records may improve documentation, but as yet, the number of studies is small and the data is restricted to one group of patients and a small group of practitioners. Further study is required to determine the benefits with handheld electronic medical records especially in assessing clinical outcomes.

Medical electronics in surgery.

I have described the results of a telemetering radio capsule which we used in the clinical assessment of digestive disease. This method has many merits which we have never found with other methods. This is one example of the clinical use of medical electronics. Medical electronics provides surgeons with many useful aids to improve diagnosis and treatment of their patients. Medical electronic technics should be used more often.

Electronic medical records and their impact on resident and medical student education.

OBJECTIVE: Electronic medical records (EMRs) are becoming prevalent and integral tools for residents and medical students. EMRs can integrate point-of-service information delivery within the context of patient care. Though it may be an educational tool, little is known about how EMR technology is currently used for medical learners. METHOD: The authors reviewed the available published literature about the impact of EMRs on learners, including learners' attitudes about EMRs, educational uses of EMRs, and the potential effects of EMRs on learners' daily work. RESULTS: Research on EMRs for education is in its infancy. The authors found fewer than 50 articles with evidence on their use in medical education. The applications to education included point-of-care knowledge delivery, computerized clinical decision support systems, profiling of learner experiences, and daily workflow management. The evidence was mainly derived from single institution studies and occasionally across disciplines. CONCLUSIONS: EMRs have great potential as an educational tool, but thus far, strong data to support their use for this are lacking. As the usage of EMRs rises, educators must continue to study how best to use technology as an educational tool and as a tool to improve the daily work of residents and medical students.

Electronic medical consultation: a New Zealand perspective.

Electronic medical consultation is available worldwide through access to the World Wide Web (WWW). This article outlines a research study on the adoption of electronic medical consultation as a means of health delivery. It focuses on the delivery of healthcare specifically for New Zealanders, by New Zealanders. It is acknowledged that the WWW is a global marketplace and that it is therefore difficult to identify New Zealanders' use of such a global market; nevertheless, we attempt to provide a New Zealand perspective on electronic medical consultation.

The medical records professionals' view of the electronic medical record.

The migration of Kaiser-Permanente (KP), a large managed care organization, to the management of health care information in a paperless environment is presented from the viewpoint of Health Information Management (HIM) professionals. The author conducted an informal survey of these professionals and presents a synopsis of their recommendations in the context of KP's efforts to develop an enterprise Electronic Medical Record. Their consensus is that physicians are primarily information managers and that successful health care organizations will be those who most effectively manage their information.

A high-level object-oriented model for representing relationships in an electronic medical record.

The importance of electronic medical records to improve the quality and cost-effectiveness of medical care continues to be realized. This growing importance has spawned efforts at defining the structure and content of medical data, which is heterogeneous, highly inter-related, and complex. Computer-assisted data modeling tools have greatly facilitated the process of representing medical data, however the complex inter-relationships of medical information can result in data models that are large and cumbersome to manipulate and view. This report presents a high-level object-oriented model for representing the relationships between objects or entities that might exist in an electronic medical record. By defining the relationship between objects at a high level and providing for inheritance, this model enables relating any medical entity to any other medical entity, even though the relationships were not directly specified or known during data model design.

Cost-justifying electronic medical records.

As interest in electronic medical record systems increases, the need to cost-justify these systems is becoming more important. But determining the cost-benefit ratio of such systems is difficult. The cost of implementing a system includes more than the price of hardware and software. It can be difficult to quantify the qualitative benefits associated with computerizing clinical information. Healthcare financial managers should be aware of the uses and limitations of financial tools for assessing electronic medical records technology.

Providers' reactions to an automated health maintenance reminder system incorporated into the patient's electronic medical record.

BACKGROUND: Automated health maintenance reminder (HMR) systems embedded in electronic medical records systems have been found to improve utilization of preventive services, but underuse persists. Our goal was to learn how to make HMRs more effective by measuring clinicians' self-reported use of HMRs and attitudes toward an HMR system embedded in an electronic medical record. METHODS: We surveyed 43 clinicians using an electronic medical record with an automated HMR system that prompted the provision of preventive or screening interventions. We measured general attitudes toward computers and the HMR, attitudes toward health maintenance, reactions to key features of the HMR system, and use of information provided by the HMR system; and we asked open-ended responses on how to improve the system. RESULTS: Seventy-five percent of clinicians reported not observing or paying attention to the HMR flashing reminder icon when reviewing a chart, and 62.8% reported they either ignored or forgot to address an alert when it appeared. Only 20% reported regularly reviewing health maintenance needs of the patient before the clinical encounter, and 56% reported seldom or never acting on HMR information during an encounter that was not health maintenance. CONCLUSIONS: This HMR system embedded in an electronic medical record was underused by clinicians, causing lost opportunities for provision of preventive care. As electronic medical records become more common, we need to find practical ways that are acceptable to clinicians to use the new capabilities the systems provide.

Electronic medical records in the outpatient setting (Part 2).

Electronic medical records are on the verge of becoming the standard within ambulatory practice. Some of the savings available to medical groups are summarized, including labor savings in clerical, front-desk, transcription, nurse and medical assistant, and physician personnel, as well as malpractice premiums, and storage and supplies. In addition to savings, an expanded revenue base may be available as electronic medical records allow personnel to see more patients. The article gives some examples of how medical practices have used electronic medical records to obtain increased revenues.

A practical procedure to prevent electromagnetic interference with electronic medical equipment.

Problems involving electromagnetic interference (EMI) with electronic medical equipment are well-documented. However, no systematic investigation of EMI has been done. We have systematically investigated the causes of EMI. The factors involved in EMI were determined as follows: 1) Electric-field intensity induced by invasive radio waves from outside a hospital. 2) Residual magnetic-flux density at welding points in a building. 3) Electric-field intensity induced by conveyance systems with a linear motor. 4) The shielding capacity of hospital walls. 5) The shielding capacity of commercial shields against a wide range frequency radio waves. 6) The immunity of electronic medical equipment. 7) EMI by cellular telephone and personal handy-phone system handsets. From the results of our investigation, we developed a following practical procedure to prevent EMI. 1) Measurement of electric-field intensity induced by invasive radio waves from outside the hospital and industrial systems in the hospital. 2) Measurement of residual magnetic-flux density at electric welding points of hospital buildings with steel frame structures. 3) Control of the electromagnetic environment by utilizing the shielding capacity of walls. 4) Measurement of the immunity of electronic medical equipment. And 5) Installation of electronic gate equipment at the building entrance to screen for handsets.

Electromagnetic interference with electronic medical equipment induced by automatic conveyance systems.

Electromagnetic interference (EMI) with electronic medical equipment induced by automatic conveyance systems is estimated. We measured the electric intensities of electromagnetic waves transmitted by three self-controlled electric truck systems. We also observed EMI with an infusion pump and a syringe pump set 1 m from the rail. The maximum electric field intensity was observed at the supplied current frequency in two systems with non-contact power supply mechanisms. The highest value, 137.0 dB microV/m, was measured just beside the rail. This is higher than the international electromagnetic immunity standard limit for electronic medical equipment. EMI may occur if electronic medical equipment is used within 2 m of the rail when the system contains an inductive power supply mechanism. With a contact power supply mechanism, the electric field intensity was much lower than that of the immunity standard. EMI should not occur even when electronic medical equipment is used just beside the rail.

Towards improvement of the accuracy and completeness of medication registration with the use of an electronic medical record (EMR).

BACKGROUND: Approximately 80% of GPs use a GP information system (GIS) and an electronic medical record (EMR) in their daily practice. To reap the full benefits of an EMR for patient care, post-graduate education and research, the data input must be well structured and accurately coded. OBJECTIVES: The quality and user-friendliness of the software positively influence the completeness and reliability of the data recorded in the GIS. To assess this in actual practice, this study examined whether or not an increase occurred in the accuracy and completeness of indication-related medication registration after the GIS's software package was upgraded. METHOD: GPs recorded data for the Registration Network Groningen (RNG) concerning four medication groups: insulin, trimethoprim, the contraceptive pill and beta-blocking agents. The completeness and accuracy of the registered data were assessed both before and after the change to the new software package. The completeness is evaluated on the basis of the indications missing for the prescribed medications. To assess accuracy, a check was made to determine whether the indications corresponded to those deemed relevant for that particular medication according to National Pharmaceutical Guidelines. RESULTS: The percentage of missing indications decreased notably, especially in the chronically prescribed medication groups. For insulin, the percentage decreased from 40.5 to 3% and for the contraceptive pill from 34.5 to 1%. For trimethoprim, the percentage decreased from 10 to 1%, and for beta-blocking agents from 22 to 1.5%. Of the indications present, the percentage of relevant indications showed a slight increase, with the largest increase observed for the contraceptive pill where the percentage rose from 86 to 96%. CONCLUSIONS: The completeness of recorded indications improved considerably after the change of software. This is due mostly to the efforts of the GPs, their practice assistants and the support of the RNG organization involved in the conversion procedure. Accuracy improved slightly, especially due to the software modifications which ensured that non-existent codes could not be entered. To summarize, with increased user-friendliness of the software, combined with the training of motivated GPs, the quality of recorded data improved.

Closing the loop of the medication use process using electronic medication administration registration.

Recent reports and studies of errors in the medication process have raised the awareness of the threat to public health. An essential step in this multi-stage process is the actual administration of a medicine to the patient. The closed loop system is thought to be a way of preventing medication errors. Current information technology can facilitate this process. This article describes the way barcode technology is being used to facilitate medication administration registration on several wards in our hospital and nursing home.
