A pilot study assessing the influences of charge data and group process on diagnostic test ordering by residents.

PURPOSE: Providing charge data to resident physicians has been shown to reduce the amounts spent on diagnostic testing. This pilot study sought to determine the influences of charge data and group decision making on diagnostic test ordering by internal medicine residents. METHOD: In an interactive workshop, 23 internal medicine residents received a hypothetical case. They completed an 18-item questionnaire estimating charges for diagnostic tests and then "ordered" tests. The residents were then randomly divided into groups that either received charge data, received charge data after ordering tests, or received no charge data. The groups ordered tests by consensus. Tests were weighted for appropriateness (+1 to +6) and inappropriateness (-1 to -6). Analyses compared individual and group decisions and effect of availability of charge data. RESULTS: Residents with access to charge data spent less on tests, but also had lower appropriateness scores. The appropriateness of the diagnostic workup was better by groups than by individuals, but cost more. CONCLUSION: Cost-containment interventions targeted towards doctors in training need to address the effect on quality of care and the influence of the group process in clinical decision making. Group diagnostic decisions may be more costly, but more appropriate.

Assessing what child health information systems should be integrated: the Michigan experience.

This project examined which child health data would be appropriate and useful to integrate with an existing real-time Michigan Department of Community Health (MDCH) application, such as the Michigan Childhood Immunization Registry. A consultant was secured to conduct data gathering analysis activities. An advisory committee of MDCH Administrators convened to guide the project. Interviews were conducted with MDCH administrators, program managers and representatives from the public and private health care provider community. These interviews focused on answering three main questions: (1) What MDCH data resources do you currently use? (2) How do you use and access these data? and (3) What is your vision for expanding, enhancing, and linking these data to meet Michigan's future health goals? Acceptance of the Michigan Childhood Immunization Registry by the pediatric and family practice community demonstrates the utility of providing more information electronically to the medical community in Michigan. The MDCH has completed a stakeholders analysis and is moving forward with requirements gathering sessions in order to create an integrated child health data system. The integrated child health data system will include data from immunizations, newborn screening, newborn hearing, lead, the Women, Infants, and Children program, and Medicaid.

Biodiversity informatics.

Biodiversity informatics is an emerging field that applies information management tools to the management and analysis of species-occurrence, taxonomic character, and image data. A wide and growing range of tools is available for both curators and researchers. The development and implementation of formal data exchange standards and query protocols have made it possible to integrate data holdings from collections around the world. The current technological environment is summarized; protocols, standards, and tools for data management, sharing, and integration are reviewed; and methods and tools for analyzing species-occurrence and character data are examined. Direct access to primary data and imagery has the power to transform the means by which taxonomy is practiced and its results disseminated to the general community.

Information technology principles for management, reporting, and research.

Information technology holds the promise to enhance the ability of individuals and organizations to manage emergency departments, improve data sharing and reporting, and facilitate research. The Society for Academic Emergency Medicine (SAEM) Consensus Committee has identified nine principles to outline a path of optimal features and designs for current and future information technology systems. The principles roughly summarized include the following: utilize open database standards with clear data dictionaries, provide administrative access to necessary data, appoint and recognize individuals with emergency department informatics expertise, allow automated alert and proper identification for enrollment of cases into research, provide visual and statistical tools and training to analyze data, embed automated configurable alarm functionality for clinical and nonclinical systems, allow multiexport standard and format configurable reporting, strategically acquire mission-critical equipment that is networked and capable of automated feedback regarding functional status and location, and dedicate resources toward informatics research and development. The SAEM Consensus Committee concludes that the diligent application of these principles will enhance emergency department management, reporting, and research and ultimately improve the quality of delivered health care.

Romanian perspective on health reporting.

Since 1990 the Romanian healthcare system has been crossing a stage of dramatic change. The healthcare reform, which is in progress, has structural, organizational and functional implications at the country level. The Ministry of Health is now preparing for the big IT changes. A Healthcare Management Information System (HMIS) will assure in the very next future automate data collection on health status of the population and on resource allocation and consumption. It is not an easy way towards the use of the Data Warehouse concept and On Line Analytical Processing technology for creating and accessing the data repository. Therefore we decided to integrate existing applications related to health system indicators until the HMIS will assure a high performance analysis and data interpretation.

Pathways to evidence-based reproductive healthcare in developing countries.

OBJECTIVE: Developing country clinicians are aware of the discourse of evidence-based medicine but heavily constrained in their ability to access and apply new knowledge. This study aimed to obtain primary descriptive data about access to and application of reproductive health-related medical knowledge in developing countries. DESIGN: Qualitative study using semi-structured interviews. SETTING: India and Yemen. SAMPLE: Forty-one doctors working in obstetrics, gynaecology, general practice and family planning services. METHODS: Interviews were tape recorded and transcribed verbatim. A theory-driven approach was conducted to carry out thematic analysis. MAIN OUTCOME MEASURES: Descriptions of experiences, attitudes and needs. RESULTS: Doctors felt the need to update their knowledge but this was not always achieved due to time and financial constraints. Alternative knowledge sources were described including the Internet, scientific meetings, medical family networks and speciality medical societies but access to these was limited by the expense of equipment, unfamiliarity with the technology and restricted advertisement of scientific meetings and conferences. Institutional hierarchy and conflict of generations were identified as barriers to change. Demoralisation was a common obstacle. On the positive side, involvement in medical education was a powerful driver for seeking new knowledge and applying research evidence to clinical practice. CONCLUSIONS: Priorities are to identify needs specific to different countries and medical settings in the developing world, access for all to full text journals and educational activities that fully engage practitioners in the early stages of their careers. Clinical teachers are the nodal group with the strongest incentive to obtain and use new knowledge.

An integrated, hospital information system based obstetrical medical record and database.

Described in this paper is the implementation and integration of an obstetrical medical record and database into an existing hospital information system. A unique feature of this system was the integration of existing data captured by the established hospital information systems with the newly implemented obstetrical database to form a complete patient data profile. This complete database integrated data from hospital functions such as demographic data obtained at patient registration, outpatient visits and tests, inpatient admission historical data, tests and procedures, newborn data and miscellaneous data required for birth registration. An important second feature was the utilization of physicians and nurses to enter the obstetrical data. This permitted immediate access to patient data from any hospital information system terminal, immediate retrieval for generating reports, and subsequently, ad hoc queries, statistical analysis and the electronic transfer of birth registration data to the State Vital Statistics Registry.

Integrated functional visualization of eukaryotic genomes.

BACKGROUND: Increasing amounts of data from large scale whole genome analysis efforts demands convenient tools for manipulation, visualization and investigation. Whole genome plots offer an intuitive window to the analysis. We describe two applications that enable users to easily plot and explore whole genome data from their own or other researchers' experiments. RESULTS: STRIPE and GFFtool (General Feature Format Tool) are softwares designed to support integration, visualization and exploration of whole genome data from eukaryotic genomes. STRIPE, in addition to providing a highly customizable and interactive data plot, provides access to numerous well-selected databases with updated information on all genes of a genome. GFFtool provides a user-friendly solution to integrating experimental data with the genomic information available in public databases. They also obviate the need for users to maintain large annotation resources, as they link to well-known resources using standard gene and protein identifiers. CONCLUSION: The programs provide the user with broad genomic overviews of data distribution, fast access to data of interest, and the ability to navigate speedily from one resource to another, and gain a better understanding of result of whole genome analysis experiments.

The coastal component of the U.S. integrated ocean observing system.

The combined effects of human activities and natural variability present significant challenges to the goals of protecting, restoring, and sustaining coastal ecosystems. Meeting these challenges and resolving conflicts in an informed fashion will require: (1) more timely detection and prediction of environmental changes and their consequences; and (2) more timely access to relevant environmental information. The achievement of these goals depends on the development of a sustained and integrated coastal ocean observing system (ICOOS) that insures timely access to the data and information required to improve: (1) climate predictions and the effects of changes in the weather on coastal populations; (2) efforts to sustain and restore healthy coastal marine ecosystems and living marine resources; and (3) compliance monitoring and evaluations of the efficacy of environmental policies. Although the responsible federal and state agencies all require similar environmental information, many separate programs have evolved for collecting, managing, and analyzing data for various purposes. Consequently, there is too much redundancy; access to diverse data from disparate sources is limited and time consuming; and individual programs are inevitably underfunded and too limited in scope. A system is needed that coordinates and integrates many of the elements of these programs to minimize redundancy, be more comprehensive, provide more timely access to data and information, and satisfy the information needs of a greater number of user groups in a more cost-effective fashion. This is the purpose of the ICOOS.

Service-oriented science.

New information architectures enable new approaches to publishing and accessing valuable data and programs. So-called service-oriented architectures define standard interfaces and protocols that allow developers to encapsulate information tools as services that clients can access without knowledge of, or control over, their internal workings. Thus, tools formerly accessible only to the specialist can be made available to all; previously manual data-processing and analysis tasks can be automated by having services access services. Such service-oriented approaches to science are already being applied successfully, in some cases at substantial scales, but much more effort is required before these approaches are applied routinely across many disciplines. Grid technologies can accelerate the development and adoption of service-oriented science by enabling a separation of concerns between discipline-specific content and domain-independent software and hardware infrastructure.

The Perinatal Database of the Netherlands.

OBJECTIVE: In the Netherlands, the Perinatal Database of the Netherlands (Landelijke Verloskunderegistratie, LVR) was set up in 1982 for secondary care obstetric departments on a voluntary participation basis, its main goal being quality monitoring. At the outset of the database, 70% of Dutch obstetric departments participated immediately. This percentage has now increased to almost 100%. How the LVR was set up, its aims, participation, general function and some aspects of the reliability are described in this article. RESULTS: Assessment of the reliability of the data on a number of points found that the frequency of various types of nearly all errors has decreased during the existence of the LVR, with the exception of a complete registration of the first-week mortality. CONCLUSIONS: The quality of the data has improved over the years. More reliable figures for the first-week mortality would be available if the LVR data were linked to those of the Neonatal Database of the Netherlands (Landelijk Neonatale Registratie, LNR), so that the condition of each child is known up to and including 28 days after birth. Improvements in the reliability of other items can be attained by implementing more checks during the data input stage and by making the data more accessible to the gynaecologists, in order to further increase motivation to record the data.

ParaDB: a tool for paralogy mapping in vertebrate genomes.

We present ParaDB (http://abi.marseille.inserm.fr/paradb/), a new database for large-scale paralogy studies in vertebrate genomes. We intended to collect all information (sequence, mapping and phylogenetic data) needed to map and detect new paralogous regions, previously defined as Paralogons. The AceDB database software was used to generate graphical objects and to organize data. General data were automatically collated from public sources (Ensembl, GadFly and RefSeq). ParaDB provides access to data derived from whole genome sequences (Homo sapiens, Mus musculus and Drosophila melanogaster): cDNA and protein sequences, positional information, bibliographical links. In addition, we provide BLAST results for each protein sequence, InParanoid orthologs and 'In-Paralogs' data, previously established paralogy data, and, to compare vertebrates and Drosophila, orthology data.

[Fistulae or catheter for elderly who start hemodialysis without permanent vascular access?].

UNLABELLED: Autologous access is the best vascular access for dialysis also in older patients and it should be mature when patient needs hemodialysis. It is not always possible. Surgeon availability and demographic characteristics of patients (age, diabetes, vascular disease...) are factors that determine primary vascular access. AIM: To analyse outcome and vascular access complications in elderly who start hemodialysis without vascular access. PATIENTS AND METHODS: All patients older than 75 years who initiated hemodialysis without vascular access between January 2000 and June 2002 were included, They were divided en two groups depending on primary vascular access. GI: arterio-venous fistulae. GIIl: Tunnelled cuffed catheter. Epidemiological and analytical data, vascular access complications related, as well as patient and first permanent vascular access survival from their inclusion in dialysis up to December 2002 were analysed and compared in both groups. RESULTS: 32 patients were studied. GI: n = 17 (4 men) and GIIl: n =1 5 (8 men), age: 79.9 +/- 3.8 and 81.7 +/- 4 years respectively (ns). There were no differences in sex and comorbidity (diabetes, ischemic heart disease, peripheral vascular disease and hypertension). It took GI 3 months to get a permanent vascular access suitable for using, while it took GIIl 1.3 months (p < 0.005) The number of temporary untunnelled catheters was higher in GI (3.35 vs 1.87 p < 0.05). Vascular access complications: 70.6% of infections occur in GI (incidence (I) = 48 infections/100 patients-year) while only 29.4% were detected in GII (I = 25 infections/100 patients-year). 70% of central venous thrombosis happen in GI (I: 25 CVT/100 patients-year) vs 30% in GIIl (I = 14.4/100 patients-year) (ns). No significant differences neither in bleeding (66.7% vs 33.3%) nor ischemia (75% vs 25%) were found. Dialysis dose (Kt/V) as well as anaemia degree were similar in both groups. Permanent vascular access survival after 2 years was 45.8% in GI and 24% in GII (ns). Patient survival was similar in GI and GII (72% vs 51% ns). CONCLUSIONS: Elderly who start hemodialysis without vascular access took longer to get a suitable permanent vascular access when arterio-venous fistulae is placed than with a tunnelled cuffed hemodialysis catheter. As a consequence, vascular access complications are larger, infection ones are the most common. In these patients a tunnelled catheter should be inserted at the time a peripheral arterio-venous access is created, in order to avoid temporary untunnelled catheters.

XEMBL: distributing EMBL data in XML format.

UNLABELLED: Data in the EMBL Nucleotide Sequence Database is traditionally available in a flat file format that has a number of known shortcomings. With XML rapidly emerging as a standard data exchange format that can address some problems of flat file formats by defining data structure and syntax, there is now a demand to distribute EMBL data in an XML format. XEMBL is a service tool that employs CORBA servers to access EMBL data, and distributes the data in XML format via a number of mechanisms. AVAILABILITY: Use of the XEMBL service is free of charge at http://www.ebi.ac.uk/xembl/, and can be accessed via web forms, CGI, and a SOAP-enabled service. SUPPLEMENTARY INFORMATION: Information on the EMBL Nucleotide Sequence Database is available at http://www.ebi.ac.uk/embl/. The EMBL Object Model is available at http://corba.ebi.ac.uk/models/. Information on the EMBL CORBA servers is at http://corba.ebi.ac.uk/

Mouse Tumor Biology Database (MTB): status update and future directions.

The Mouse Tumor Biology (MTB) database provides access to data about endogenously arising tumors (both spontaneous and induced) in genetically defined mice (inbred, hybrid, mutant and genetically engineered mice). Data include information on the frequency and latency of mouse tumors, pathology reports and images, genomic changes occurring in the tumors, genetic (strain) background and literature or contributor citations. Data are curated from the primary literature or submitted directly from researchers. MTB is accessed via the Mouse Genome Informatics web site (http://www.informatics.jax.org). Integrated searches of MTB are enabled through use of multiple controlled vocabularies and by adherence to standardized nomenclature, when available. Recently MTB has been redesigned and its database infrastructure replaced with a robust relational database management system (RDMS). Web interface improvements include a new advanced query form and enhancements to already existing search capabilities. The Tumor Frequency Grid has been revised to enhance interactivity, providing an overview of reported tumor incidence across mouse strains and an entrée into the database. A new pathology data submission tool allows users to submit, edit and release data to the MTB system.

Current status of Image Save and Carry (IS&C) standardization.

Image Save And Carry (IS&C) was planned to be an off-line information system for transmission and exchange of medical images and information between a medical facility's different divisions as well as between other hospitals. The IS&C committee defines file format for magneto-optical disk, the data format and representation, media compatibility and data security and technological assessment. A 'zone management method' which contributes to a rapid access of data in the recording media is used for IS&C file management. The IS&C standard holds as much conformation as possible in order to coordinate with ACR-NEMA (American College of Radiology-National Electrical Manufacturers' Association) and MIPS (Medical Information Processing Systems) standards. The IS&C data format is based upon the ACR-NEMA/MIPS standard. A major difference between the ACR-NEMA/MIPS standard and IS&C standard is that the IS&C standard is expected to serve for recording all kinds of medical information (e.g., diagnostic reports, endoscopic images and electrocardiograms), including X-ray images. Applications to PACS, teaching files, personal electronic health and medical records are promising. The booklet of IS&C standard will be published in the spring of 1992 by the IS&C committee.

Integrating plant phenotypic and genotypic data in the AGENT project: a BrAPI service implementation.

MOTIVATION: The AGENT project established a network of actively cooperating European genebanks, integrating genomic and phenotypic data from accessions of wheat and barley. Due to specific storage demands for phenotypic and genotypic data, the project used separate database instances and backend technologies to manage integrated phenotypic and genotypic data. RESULTS: We discuss the challenges encountered when integrating dispersed data to serve through a single interface such as the Plant Breeding Application Programming Interface, BrAPI. We examine how the consistent mappability of genebank data to the BrAPI model can enable the implementation of effective services. The advantages of BrAPI in transparently linking distributed data entities through embedded, unique identifiers are highlighted. We present a technical solution involving a BrAPI proxy, which combines and merges separate BrAPI endpoints. Finally, we demonstrate the AGENT BrAPI implementation with an illustrative example that validates a suggested SNP for a trait from the literature by linking phenotypic, genotypic and passport data. AVAILABILITY AND IMPLEMENTATION: The BrAPI proxy implementation and documentation is available at the Python Package Index (https://pypi.org/project/brapi-proxy) and archived in Zenodo (doi: 10.5281/zenodo.19436445). SUPPLEMENTARY INFORMATION: A Jupyter Notebook file for the validation example using a marker-trait relationship found in the literature.
