Finding the answers in primary care: information seeking by rural and nonrural clinicians.

BACKGROUND: Information systems for rural practice may assume that rural clinicians have different information seeking, but studies have not directly compared rural and nonrural information needs using common methodology. OBJECTIVE: Compare rural and non-rural: 1) information needs; 2) information seeking; 3) effectiveness of information seeking; and 4) use of information resources. DESIGN: Observation and interviews during one half-day of office practice; telephone follow-up 2-10 days later. PARTICIPANTS & SETTING: Primary care physicians (39), nurse practitioners (42), and physician assistants (22) in ambulatory practices in rural and nonrural Oregon. MEASURES: 1) number of questions asked, 2) number of questions pursued, 3) number of questions answered), and 4) use of knowledge resources. RESULTS: Rural clinicians practiced in smaller groups, but were otherwise similar to nonrural clinicians. During half-day interviews, clinicians cared for an average of 8.2 patients (95% CI 7.5 - 8.8) and asked an average of 0.83 questions per patient seen (95% CI 0.73 - 0.92). At follow up, they had pursued an average of 47% of their questions (95% CI 40 - 53%), and reported being successful in finding an answer to 77% of those they pursued (95% CI 70 - 84%). There were no statistically significant differences between rural and nonrural clinicians for any of these variables. CONCLUSIONS: Rural and nonrural clinicians had similar information needs, information seeking, knowledge resource use, and effectiveness at finding answers to their questions. Human consultants, digital resources, and library-based resources were less available, but these differences in availability had little impact on their use.

Telelearning standards and their application in medical education.

Medial education, both on the graduate and postgraduate levels, has become a real challenge nowadays. The volume of information in medical sciences grows so rapidly that many health professionals experience essential problems in keeping track of the state of the art in this domain. e-learning offers important advantages to medical education continuation due to its universal availability and opportunity for implementation of flexible patterns of training. An important trace of medical education is developing practical skills. Some examples of standardization efforts include: the CEN/ISSS Workshop on Learning Technology (WSLT), the Advanced Learning Infrastructure Consortium (ALIC), Education Network Australia (EdNA) and PROmoting Multimedia access to Education and Training in European Society (PROMETEUS). Sun Microsystems' support (Sun ONE, iPlanetTM ) for many of the above-mentioned standards is described as well. Development of a medical digital video library with recordings of invasive procedures incorporating additional information and commentary may improve the efficiency of the training process in interventional medicine. A digital video library enabling access to videos of interventional procedures performed in the area of thoracic medicine may be a valuable element for developing practical skills. The library has been filled with video resources recorded at the Department of Interventional Pulmonology; it enhances training options for pulmonologists and thoracic surgeons. The main focus was put on demonstration of bronchofiberoscopic and videothoracoscopic procedures. The opportunity to browse video recordings of procedures performed in the specific field also considerably enhances the options for training in other medical specialties. In the era of growing health consumer awareness, patients are also perceived as the target audience for medical digital libraries. As a case study of Computer-Based Training systems, the Medical Digital Video Library is presented.

The dragon on the gold: myths and realities for data mining in biomedicine and biotechnology using digital and molecular libraries.

To develop bioscience and personalized medicine in the post-genomic era, the biggest problem may be how to extract knowledge from the rich libraries of biomedical data. A particular dragon protects the gold therein: the dragon is the "curse of dimensionality" and its formidable fire weapon, which is burning researchers, is the "combinatorial explosion". This arises because many genomic, proteomic, clinical, and lifestyle factors may interact that cannot necessarily be considered on a simple pairwise or additive basis. A suggested theoretical solution--or at least "road map" that ameliorates management of these problems--borrows from several disciplines. It is undertaken also in the hope might also lead to research with broader impact on several unresolved issues in biotechnology: conversely, mathematical understanding of processes involving molecular libraries, such as cDNA libraries and DNA in the living cell itself, may open the opportunities to use biotechnology to construct nanotechnological storage and query systems.

Applying Hybrid-Asbru clinical guidelines using the Spock system.

Clinical Guidelines are a major tool for improving the quality of medical care. Currently, a major research direction is automating the application of guidelines at the point of care. To support that automation, several requirements must be fulfilled, such as specification in a machine-interpretable format, and connection to an electronic patent record. We propose an innovative approach to guideline application, which capitalizes on our Digital electronic Guidelines Library (DeGeL). The DeGeL framework includes a new hybrid model for incremental specification of free-text guidelines, using several intermediate representations. The new approach was implemented, in the case of the Asbru guideline ontology, as the Spock system. Spock's hybrid application engine supports application of guideline represented at an intermediate format. Spock was evaluated in a preliminary fashion by applying several guidelines to sample patient data.

Image acquisition context: procedure description attributes for clinically relevant indexing and selective retrieval of biomedical images.

OBJECTIVE: To support clinically relevant indexing of biomedical images and image-related information based on the attributes of image acquisition procedures and the judgments (observations) expressed by observers in the process of image interpretation. DESIGN: The authors introduce the notion of "image acquisition context," the set of attributes that describe image acquisition procedures, and present a standards-based strategy for utilizing the attributes of image acquisition context as indexing and retrieval keys for digital image libraries. METHODS: The authors' indexing strategy is based on an interdependent message/terminology architecture that combines the Digital Imaging and Communication in Medicine (DICOM) standard, the SNOMED (Systematized Nomenclature of Human and Veterinary Medicine) vocabulary, and the SNOMED DICOM microglossary. The SNOMED DICOM microglossary provides context-dependent mapping of terminology to DICOM data elements. RESULTS: The capability of embedding standard coded descriptors in DICOM image headers and image-interpretation reports improves the potential for selective retrieval of image-related information. This favorably affects information management in digital libraries.

Digital reference service: trends in academic health science libraries.

Two years after the initial 2002 study, a greater number of academic health science libraries are offering digital reference chat services, and this number appears poised to grow in the coming years. This 2004 follow-up study found that 36 (27%) of the academic health science libraries examined provide digital chat reference services; this was an approximately 6% increase over the 25 libraries (21%) located in 2002. Trends in digital reference services in academic health science libraries were derived from the exploration of academic health science library Web sites and from digital correspondence with academic health science library personnel using e-mail and chat. This article presents an overview of the current state of digital reference service in academic health science libraries.

Evaluation of the KA24 (Knowledge Access 24) service for health and social care staff in London and the south-east of England. Part 2: qualitative.

AIM AND OBJECTIVES: The aim of this two-part paper is to identify the main transferable lessons learned from both the quantitative and qualitative evaluations of the KA24 (Knowledge Access 24) service of online databases and selected full-text journals for health and social care staff in London and the south-east of England. The objectives of the qualitative evaluation were to assess the enablers and barriers to usage, and to assess the impact of the service on patient care. METHODS: Telephone interviews (n = 65) and a questionnaire survey (n = 296) were conducted with various types of user, in various Trust settings. Some non-users were also contacted. Selection of interviewees and questionnaire recipients was not random, and aimed to cover all groups of users representatively. RESULTS: Results show that policy goals were being delivered, with indications of changes to clinical practice, and improved clinical governance. Promotion, training and support needs to be extensive, and tailored to needs, but users are not always aware they need training. The sharing of passwords cast doubts on the reliability of some usage data. CONCLUSIONS: Digital health library services, delivered at the point of care, are changing the way some clinicians practise. A combination of qualitative and quantitative evaluation methods are needed to assess digital library services.

Improving usage of pediatric information on the Internet: the Virtual Children's Hospital.

OBJECTIVE: Digital health sciences libraries (DHSLs) bring order to the chaos of the Internet by making authoritative medical information easily and conveniently available to patrons. The goal of this project was to perform a baseline usage analysis of the pediatric-related information in a general DHSL and to determine whether reorganization of the pediatric-related information into its own pediatric DHSL could increase the usage of the pediatric-related information. METHODS: From March through August 1997, a baseline analysis of a general DHSL (Virtual Hospital) was conducted using computer server log file analysis programs. The quantity of pediatric-related information in the general DHSL and its baseline usage were determined. In September 1997, the pediatric-related information was reorganized into its own pediatric DHSL (Virtual Children's Hospital), and server log file analyses were conducted of the pediatric DHSL from September 1997 to August 1998. Statistical analysis was performed by time series autoregression. RESULTS: During the baseline, the general DHSL and the pediatric-related information received a monthly average of 2 320 782 and 141 444 qualified hits, respectively. After the intervention, the general DHSL and the pediatric DHSL received a monthly average of 2 765 454 and 256 998 qualified hits, respectively. This is an increase of 19. 2% for the general DHSL and 81.7% for the pediatric DHSL. These changes were statistically significant at the P >.0001 level. The most requested pediatric-related content in the pediatric DHSL did not change substantively from preintervention to postintervention. DISCUSSION: On the Internet, as in real life, children's services must have their own distinct identity and must be differentiated from adult services. Therefore, pediatric-related information will receive increased usage if it is part of a pediatric DHSL rather than part of a general DHSL. Others can use this process and the lessons learned to develop and enhance their own pediatric-related information on the Internet.

Cognitive engineering of film library transition from film medium to digital environment in a Texas teaching hospital.

Digital imaging technology promises efficient, economical, and fast service for patient care, but the challenges are great in the transition from film to a filmless (digital) environment. This change has a significant impact on the film library's personnel (film librarians) who play a leading roles in storage, classification, and retrieval of images. The objectives of this project were to study film library errors and the usability of a physical computerized system that could not be changed, while developing an intervention to reduce errors and test the usability of the intervention. Cognitive and human factors analysis were used to evaluate human-computer interaction. A workflow analysis was performed to understand the film and digital imaging processes. User and task analyses were applied to account for all behaviors involved in interaction with the system. A heuristic evaluation was used to probe the usability issues in the picture archiving and communication systems (PACS) modules. Simplified paper-based instructions were designed to familiarize the film librarians with the digital system. A usability survey evaluated the effectiveness of the instruction. The user and task analyses indicated that different users faced challenges based on their computer literacy, education, roles, and frequency of use of diagnostic imaging. The workflow analysis showed that the approaches to using the digital library differ among the various departments. The heuristic evaluation of the PACS modules showed the human-computer interface to have usability issues that prevented easy operation. Simplified instructions were designed for operation of the modules. Usability surveys conducted before and after revision of the instructions showed that performance improved. Cognitive and human factor analysis can help film librarians and other users adapt to the filmless system. Use of cognitive science tools will aid in successful transition of the film library from a film environment to a digital environment.

Implementing PDA technology in a medical library: experiences in a hospital library and an academic medical center library.

Personal digital assistants (PDAs) have grown from being a novelty in the late 1990s to an essential tool for healthcare professionals in the 2000s. This paper describes the experiences of a librarian who implemented PDA technology first in a hospital library, and then at an academic medical center library. It focuses on the role of the library in supporting PDA technology and resources. Included are programmatic issues such as training for library staff and clinicians, and technical issues such as Palm and Windows operating systems. This model could be used in either a hospital or academic health sciences library.

Medical video server construction.

The paper discusses two implementation options for a Digital Video Library, a repository used for archiving, accessing, and browsing of video medical records. Two crucial issues to be decided on are a video compression format and a video streaming platform. The paper presents numerous decision factors that have to be taken into account. The compression formats being compared are DICOM as a format representative for medical applications, both MPEGs, and several new formats targeted for an IP networking. The comparison includes transmission rates supported, compression rates, and at least options for controlling a compression process. The second part of the paper presents the ISDN technique as a solution for provisioning of tele-consultation services between medical parties that are accessing resources uploaded to a digital video library. There are several backbone techniques (like corporate LANs/WANs, leased lines or even radio/satellite links) available, however, the availability of network resources for hospitals was the prevailing choice criterion pointing to ISDN solutions. Another way to provide access to the Digital Video Library is based on radio frequency domain solutions. The paper describes possibilities of both, wireless and cellular network's data transmission service to be used as a medical video server transport layer. For the cellular net-work based solution two communication techniques are used: Circuit Switched Data and Packet Switched Data.

Integrating digital topology in image-processing libraries.

This paper describes a method to integrate digital topology informations in image-processing libraries. This additional information allows a library user to write algorithms respecting topological constraints, for example, a seed fill or a skeletonization algorithm. As digital topology is absent from most image-processing libraries, such constraints cannot be fulfilled. We describe and give code samples for all the structures necessary for this integration, and show a use case in the form of a homotopic thinning filter inside ITK. The obtained filter can be up to a hundred times as fast as ITK's thinning filter and works for any image dimension. This paper mainly deals of integration within ITK, but can be adapted with only minor modifications to other image-processing libraries.

Computerized case-based instructional system for computed tomography and magnetic resonance imaging of brain tumors.

RATIONALE AND OBJECTIVES: A computerized system that applies the case-based approach to training radiologists to diagnose brain tumors was designed. The authors attempted to provide residents a tool that supports their visual memory and inducts case-based reasoning. METHODS: A relational database with a digital image library was implemented and incorporated into a computer aided instruction environment based on case presentation. An indexing system was structured around case features (case history and radiologic findings). "If-then" type rules were used to control the search direction within the case library and to generate lists of diagnostic hypotheses. The indexing system was evaluated against cases "known" to the system. RESULTS: The current case library consists of 122 cases with 640 digitized images (computed tomography and magnetic resonance imaging). The accuracy of retrieval for "known" to the system cases was 80.7%. CONCLUSIONS: A case library stored on a personal computer can be efficiently searched for a combination of radiologic findings and can offer quality images for comparison to the case in question. A case library is a source of the information that may be used by different teaching applications.

Semi-automatic indexing of full text biomedical articles.

The main application of U.S. National Library of Medicine's Medical Text Indexer (MTI) is to provide indexing recommendations to the Library's indexing staff. The current input to MTI consists of the titles and abstracts of articles to be indexed. This study reports on an extension of MTI to the full text of articles appearing in online medical journals that are indexed for Medline. Using a collection of 17 journal issues containing 500 articles, we report on the effectiveness of the contribution of terms by the whole article and also by each section. We obtain the best results using a model consisting of the sections Results, Results and Discussion, and Conclusions together with the article's title and abstract, the captions of tables and figures, and sections that have no titles. The resulting model provides indexing significantly better (7.4%) than what is currently achieved using only titles and abstracts.

Microscopic photography for the restorative dentist.

UNLABELLED: Obtaining quality 35 mm photographs through an operating microscope challenges even the best of operators, and few clinicians have actually mastered the technique. This article discusses how to easily obtain quality high-resolution digital photographs at various magnifications using an operating microscope by adopting a technique that is easy to master and can be accomplished by any clinician who learns the skills. This review summarizes the advantages and disadvantages of microscopic photography, with a particular emphasis on digital photography. There is a discussion of the required equipment and necessary technique. The value of using digital photographic libraries at chair-side is explored. CLINICAL SIGNIFICANCE: Since the photographic skill with digital photography is easily mastered, clinicians can now more thoroughly document their cases and enhance their case-presentation skills. Teachers and lecturers can also draw upon large photographic relational databases to expand their presentation capabilities.
