A MEDLINE categorization algorithm

BackgroundCategorization is designed to enhance resource description by organizing content description so as to enable the reader to grasp quickly and easily what are the main topics discussed in it. The objective of this work is to propose a categorization algorithm to classify a set of scientific articles indexed with the MeSH thesaurus, and in particular those of the MEDLINE bibliographic database. In a large bibliographic database such as MEDLINE, finding materials of particular interest to a specialty group, or relevant to a particular audience, can be difficult. The categorization refines the retrieval of indexed material. In the CISMeF terminology, metaterms can be considered as super-concepts. They were primarily conceived to improve recall in the CISMeF quality-controlled health gateway.MethodsThe MEDLINE categorization algorithm (MCA) is based on semantic links existing between MeSH terms and metaterms on the one hand and between MeSH subheadings and metaterms on the other hand. These links are used to automatically infer a list of metaterms from any MeSH term/subheading indexing. Medical librarians manually select the semantic links.ResultsThe MEDLINE categorization algorithm lists the medical specialties relevant to a MEDLINE file by decreasing order of their importance. The MEDLINE categorization algorithm is available on a Web site. It can run on any MEDLINE file in a batch mode. As an example, the top 3 medical specialties for the set of 60 articles published in BioMed Central Medical Informatics & Decision Making, which are currently indexed in MEDLINE are: information science, organization and administration and medical informatics.ConclusionWe have presented a MEDLINE categorization algorithm in order to classify the medical specialties addressed in any MEDLINE file in the form of a ranked list of relevant specialties. The categorization method introduced in this paper is based on the manual indexing of resources with MeSH (terms/subheadings) pairs by NLM indexers. This algorithm may be used as a new bibliometric tool.

An open repositories network development for medical teaching resources

The lack of interoperability between repositories of heterogeneous and geographically widespread data is an obstacle to the diffusion, sharing and reutilization of those data. We present the development of an open repositories network taking into account both the syntactic and semantic interoperability of the different repositories and based on international standards in this field. The network is used by the medical community in France for the diffusion and sharing of digital teaching resources. The syntactic interoperability of the repositories is managed using the OAI-PMH protocol for the exchange of metadata describing the resources. Semantic interoperability is based, on one hand, on the LOM standard for the description of resources and on MESH for the indexing of the latter and, on the other hand, on semantic interoperability management designed to optimize compliance with standards and the quality of the metadata.

Intermediation: a new concept for medical data exchanges

With the development of the Information and Communication Technologies, the exchanges of data between Healthcare Professionals are modified. Hospitals and Private Clinics are installing their Hospital Information Systems, while the General Practitioners are computing their patients records. Therefore the environment is suitable for the installation and diffusion of telematics services allowing better exchanges of information between the physicians of a geographical sector. The Intermediation platform was developed to provide an asynchronous n to n communication. It ensures several functions such as: movements of the patients (in/out/inside) the hospital, management and mailing of letters and reports, specific information about the treatments or data concerning the hospital structure. On the other hand, the G.P.s can send medical records to their hospital correspondents. This platform has been used in the town of Armentieres in the city of Lille (North of France). It is currently routinely used to accelerate and secure data exchanges between all the physicians working in this area.

Activity analysis for designing an anesthesia record system

In a context of increasing development of Information Systems and computers in the hospitals, the departments of anesthesiology display an important demand for sessions. Software applications able to support the medical activity all along the anesthetic process. The authors focus here on the preoperative phase. Some medical departments of anesthesiology have developed software applications supporting data gathering during the anesthetic consultation. But the daily use of these computerized medical files is usually limited to some medical units and to a limited number of physicians in the units. The usual explanations given for this lack of dissemination stress resistance to changes or insufficient training. The authors assume that most of the actual software applications do not properly handle medical cognitive activity, thus creating cognitive conflicts during physician-machine interaction. An experimental and functional assessment of such an anesthetic software application clearly demonstrates the incompatibility between the structure of the interface and the usual expert strategies and procedures implemented by the anesthetists when performing the preoperative consultation.

Health Logistics: Toward Collaborative Approaches and Tools

Abstract: In the field of health we traditionally speak of health logistics, which is split into two sections: hotel services (meals, laundry, etc.) and medicotechnical services (which strictly refer to medical activities).

Mapping patient flow in the Jeanne de Flandres Hospital's operating rooms

The purpose of this paper is twofold: to depict the patients journey in operating block of the hospital and to provide a flexible model that matches the reality. In operating block of Jeanne de Flandres Hospital, a daily meeting is held in order to establish the operations that will occur the next day. Organizing a schedule in these circumstances leads to a loss of time and can often lead to conflictual situations. The overall study objective is therefore to provide an interactive schedule. Hence, we will need to consider parameters such as the type of surgery, patients age, and their past history. From model analysis, some operations duration will be estimated.

La e-Santé

Apres avoir lu ce chapitre, vous devriez : pouvoir definir la e-Sante ; connaitre les grandes etapes du developpement de la e-Sante depuis les annees 1960 ; pouvoir expliquer quels sont les impacts attendus de la e-Sante ; savoir definir ce qu’est le travail cooperatif ; savoir definir ce qu’est la telesante et ses differentes composantes (telesurveillance, teleconsultation…) ; pouvoir expliquer l’impact des nouvelles technologies de l’information et de la communication sur le maintien de l’autonomie.

Carnet de l'interne augmenté pour l'apprentissage pervasif pendant l'activité de soins

Peu de documents pedagogiques sont consultes pendant l’activite de soins. Or de nos jours, de nombreux outils mobiles pourraient s’integrer dans l’activite. Nous presentons nos recherches autour de la production de documents pedagogiques, accessibles de facon pervasive. Tout d’abord, nous presentons le contexte des enseignements en sante, rarement concus pour etre consultes pendant l’activite de soins et celui de l’utilisation d’outils mobiles. Et nous introduisons notre objectif d’apprentissage pervasif. Dans une seconde partie, nous presentons les analyses que nous avons menees dans les services hospitaliers, d’une part, pour comprendre ou et quand se deroulent les echanges pedagogiques, d’autre part, pour analyser le type de documents echanges. Le carnet de l’interne retient notre attention. La section 3 decrit un modele de carnet augmente ainsi que l’implementation qui en est proposee, avant d’aborder les sections de discussion et de conclusion.

Placoweb: intranet technologies and cooperative work

Cooperation between health care professionals is essential for the quality of care. Workflow systems could improve the transfer of information and responsibilities between health care actors. To manage the whole cooperation system-connection of the actors, security, coordination-a modular system is required. New Internet technologies could anchor information exchange through distributed applications, easy to use with well-known interfaces.
