TL;DR: The National Library of Medicine's Visible Human Male data set consists of digital magnetic resonance (MR), computed tomography (CT), and anatomic images derived from a single male cadaver.

TL;DR: Evidence from randomized controlled studies supports the effectiveness of data-driven computer-based reminder systems to improve prevention services in the ambulatory care setting.

TL;DR: A synthesis of research carried out at Stanford University to model the therapy-planning task and to demonstrate a component-based architecture for building protocol-based decision-support systems is presented.

TL;DR: The authors review the conflicting goals of accessibility and security for electronic medical records and discuss nontechnical and technical aspects that constitute a reasonable security solution.

TL;DR: In this paper, the authors evaluate user satisfaction, correlates of satisfaction, and self-reported usage patterns regarding physician order entry (POE) in one hospital and find that POE features directed at improving the quality of care were less strongly correlated with satisfaction.

TL;DR: In this paper, the authors evaluated major clinical classifications for their content coverage and found that ICD-9-CM and CPT failed to capture substantial clinical content, while SNOMED performed the best.

TL;DR: The most effective extension to the EMR studied would be to expand its scope to include all clinicians who can potentially change medications, and the provision of a free-text “comments” field increased the accuracy of medication lists for clinician users at the expense of accuracy for a MDSS.

TL;DR: A preliminary EMRS architecture (W3-EMRS) is designed that exploits the multiplatform, multiprotocol, client-server technology of the World Wide Web to enable implementation of programs that provide uniform access to multiple, heterogeneous legacy EMRSs.

TL;DR: The Internet and hypertext origins of the WWW are summarized, WWW-specific technologies are reviewed, and current and future applications of this technology in medicine and medical informatics are described.

TL;DR: Conventional approaches to data modeling can be used to develop rich, complex models of clinical data that are useful for understanding and managing the process of patient care but are not flexible enough to meet the needs of an operational clinical information system.

TL;DR: CliniWeb is an index to clinical information on the World Wide Web, providing a browsing and searching interface to clinical content at the level of the health care student or provider, and limitations of the processes used to build the database are discussed.

TL;DR: The ability to identify a small number of expert-like strategies within a large body of student performances may provide an opportunity to study the dynamics of complex learning at both individual and population levels as well as the emergence of medical diagnostic expertise.

TL;DR: The pen-based progress-note-writing system PEN-Ivory as discussed by the authors allows physicians to write patient progress notes using simple penbased gestures such as circle, line-out, and scratch-out.

TL;DR: The intervention physicians did not use the Physician Workstation frequently enough to influence information-seeking behavior, health outcomes, or cost, and the study design did not determine whether the poor usage resulted from satisfaction with the control system, problems using the PWS intervention, or the functions provided.

TL;DR: Investigating a new approach for query expansion based on retrieval feedback indicated that retrieval-feedback-based expansion yields significant performance improvements independent of the availability of relevant documents for feedback information.

TL;DR: Physicians can now pose a limited, predefined set of clinically relevant questions to the system without having to be at the patient's bedside, and the system creates and continuously updates a database of all monitored parameters in data formats that can readily be used for further clinical studies.

TL;DR: AIM must move forward with the insights that it has gained and focus on finding solutions for problems at the heart of medical practice, and the growing emphasis within medicine on evidence-based practice should provide the right environment for that change.

TL;DR: This paper describes a pilot project in which a database of computational models of neuronal function is constructed, which allows models to be created and run and their results reviewed through a World Wide Web interface.

TL;DR: System evaluation in biomedical informatics should take place as an ongoing, strategically planned process, not as a single event or a small number of episodes, so evaluators and readers of evaluations face moving targets.

TL;DR: Query by Review, with its more constrained user interface, performed somewhat better than AccessMed, a more general tool, which points to the difficulty of formulating a query for a clinical database and the need for further work.

TL;DR: In this paper, the authors assess the effects of incomplete data upon the output of a computerized diagnostic decision support system (DSS), and explore if these effects vary as a function of clinical experience.

TL;DR: The production of a correct diagnosis for a given case is not related to the number of diagnoses suggested by the DDSS and is not consistently related to other measures of performance, indicating that multiple measures are needed to fully describe the performance of a D DSS.

TL;DR: The mapping of an institutional vocabulary to a structured controlled vocabulary requires that the mapping be performed at the level of terms, relationships, and attributes, and revealed the importance of standardization of local vocabulary subsets, standardized of attribute representation, and term granularity.

TL;DR: The Implementation phase asks one question: How does an organization create an environment that redirects and coordinates a variety of individual activities so that they come together to provide an IAIMS?

TL;DR: Metrics collected during the routine use of the GermWatcher expert system can be used to monitor the performance of the expert system and can be followed using continuous user feedback without requiring extensive formal evaluations after each modification.

TL;DR: A set of statistical process control tools that can be used to monitor the performance of a number of deployed medical expert systems are described.

TL;DR: The National Library of Medicine (NLM) and the Agency for Health Care Policy and Research (AHCPR) are sponsoring a test to determine the extent to which a combination of existing health-related terminologies covers vocabulary needed in health information systems.

TL;DR: The results of this study indicate that diagnostic images such as x-rays and magnetic resonance images could be routinely encrypted in PACS, however, applying encryption in teleradiology and PACS is a tradeoff between communications performance and security measures.

TL;DR: The QFES provides a flexible tool for the implementation of clinical practice guidelines in diverse and changing clinical areas without the need for special program development and preliminary studies indicate utility in the analysis ofclinical practice variation and deviations.
