Effet de la familiarisation sur lâĂ©volution des perceptions dâutilitĂ© et dâutilisabilitĂ© dâune plateforme web de dermatologie
Dans cette Ă©tude, nous proposons dâĂ©tudier dans quelle mesure une familiarisation prĂ©alable Ă un usage dâun outil basĂ© sur les Technologies de lâinformation et la communication (TIC) favorise ou non une Ă©volution positive de la qualitĂ© des perceptions (utilitĂ© et utilisabilitĂ©) de lâutilisateur. Ces perceptions dĂ©terminent selon le modĂšle dâacceptation des technologies (TAM) de Davis (1989) les intentions dâusage et lâusage rĂ©el de lâoutil. Cette recherche menĂ©e sur une pĂ©riode de 5 mois auprĂšs de 103 mĂ©decins en formation est basĂ©e sur lâusage de la plateforme on-line en dermatologie pour peaux noires « Black-Skin6 ». Deux groupes ont Ă©tĂ© constituĂ©s. Lors de la premiĂšre phase, le groupe 1 participait Ă des tests en laboratoire dâutilisabilitĂ©. Au cours de la deuxiĂšme phase, les deux groupes avaient Ă se prĂ©parer Ă un test de connaissance en dermatologie sur peaux noires via la plateforme Black-Skin. Enfin, lors de la phase 3, les 2 groupes passaient le test de connaissance. Ă chaque phase a Ă©tĂ© associĂ© un questionnaire mesurant lâutilitĂ© et lâutilisabilitĂ© perçue sur base des items proposĂ©s par Davis (1989). Les rĂ©sultats de cette Ă©tude nous permettent de montrer que la familiarisation avec lâoutil (par le biais des tests dâutilisabilitĂ©) constitue un moteur Ă lâĂ©volution de la facilitĂ© dâutilisation perçue ainsi quâĂ son utilitĂ© perçue et quâelle a un effet significatif sur la performance au test de connaissance. DĂšs lors, une premiĂšre phase de familiarisation contribuerait Ă amĂ©liorer lâintention dâusage et lâusage rĂ©el dâoutils de formation et dâaide au diagnostic dans les milieux mĂ©dicaux ainsi que la qualitĂ© des apprentissages en ligne.info:eu-repo/semantics/publishe
Approche diffĂ©rentielle des performances lors de tests dâutilisabilitĂ© :Ă©tude de lâinfluence de variables culturelles et contextuelles
LâĂ©tude de la variabilitĂ© dans lâanalyse des performances de tests dâutilisabilitĂ© amĂšne Ă prendre en compte lâinfluence de variables culturelles et contextuelles. Lors de lâĂ©tude de lâutilisabilitĂ© dâune plateforme web en dermatologie « peaux noires », cinquante tests ont Ă©tĂ© rĂ©alisĂ©s auprĂšs de 2 groupes "Ă©quivalents" de mĂ©decins en formation provenant de deux universitĂ©s belges. Des analyses de lâefficacitĂ© et de lâefficience globales font apparaĂźtre des diffĂ©rences significatives entre les deux groupes. Cette communication vise Ă apprĂ©hender les facteurs explicatifs de cette variabilitĂ© Ă partir dâune analyse approfondie des donnĂ©es recueillies (donnĂ©es dâobservations et rĂ©ponses Ă un questionnaire post-test).info:eu-repo/semantics/nonPublishe
Black-Skin Online: Library of medicine as operator for an open access atlas
Background: Teledermatology is a developing field which has the potential to provide remote dermatology services. Up to now there is no teledermatology service specifically dedicated to black skins whereas, on the one hand, Africa suffers a substantial lack of skin care and, on the other hand, there is an increasing number of dark-skinned patients in Western European countries. A few years ago this lack was identified by the Library of Medicine (of UniversitĂ© Libre de Bruxelles) and the dermatology service of the academic hospital Erasme; together, they launched the project BlackSkin Dermatology Online with the support of federal grants.Methods: BlackSkin Dermatology Online is a project funded by the Belgian Federal Government that takes place in two phases, each phase lasting two years. During the first phase, images have been collected from Belgium (existing slides collections owned by Belgian university hospitals) and from Senegal (new photographs collected with the help of a local partner). Simultaneously, a web prototype has been built using open source technology. During the second phase, the specific needs of the target users (medical students, dermatologists, medical practitioners) have been studied. Thus, usability tests have been performed within a usability laboratory and further information has been collected by means of specific questionnaires in order to customize the web interfaces.Results: A high quality image bank has been built. Each image is described along specific parameters (morphologic description, ICD10 classification,). This image bank is the core of an open access web prototype which aims to offer retrieval and viewing tools as well as remote services such as image submission or âask for a diagnosisâ. In parallel, users can submit images which go through a peer review process as in any other scientific publication system. Moreover, specific plugins have been developed with an open source content system management. Finally, user testing has lead to the conception of specific validated test protocols. Representative tasks were identified thanks to observations of the usage of the web interface by groups of users and to interviews (search of image, learning, check diagnostic, etc.).Discussion: This teledermatology project could be a very helpful tool in providing skin care in Southern regions where populations suffer from a substantial lack of medical services as well as limited means of transportation. At the same time, dermatology relies on the visual inspection of the skin and teledermatology offers such an opportunity for North and South practitioners. User testing has enabled tasks scenarios to be validated, offering the basic framework for similar projects in telemedicine, as retrieval of relevant visual information is of prime importance in medicine. One limitation in our study is linked to the use of open source technology, as this is time consuming and involves the creation of specific plugins at each step of the process. Nevertheless, the originality of our approach resides in the use of usability methods in order to optimize the user-friendliness of the web interface.info:eu-repo/semantics/nonPublishe

Current and future directions in Belgian medical and health sciences librarianship: a user-tailored approach
This article is part of a new series in this regular feature. The series intend to serve as a road map by sharing expertise and drawing together trends that are relevant to both health science librarians and health informatics professionals. The present article is a collaboration of six medical and health sciences libraries in Belgium and the Flemish library and archive association (VVBAD, n.d., https://www.vvbad.be/). It aims to elucidate the extended, userâtailored approach provided by medical and health sciences libraries in Belgium motivated by the recent changes in user expectations and behaviour
