Objectif G\u00e9n\u00e9ral <\/strong><\/p>\n

Adapter le logiciel CAD au contexte \u00e9pid\u00e9miologique et op\u00e9rationnel de la Guin\u00e9e pour renforcer le d\u00e9pistage de la tuberculose.<\/p>\n

Objectifs sp\u00e9cifiques <\/strong><\/p>\n

    \n
  • D\u00e9terminer le seuil du score d'anomalie du logiciel CAD qui maximise la sensibilit\u00e9 ou la sp\u00e9cificit\u00e9 du d\u00e9pistage de la tuberculose en Guin\u00e9e.<\/li>\n
  • Comparer le logiciel CAD \u00e0 la lecture humaine des radiographies pulmonaires et aux tests de r\u00e9f\u00e9rence (GeneXpert, cliniciens...) pour le diagnostic de la tuberculose.<\/li>\n
  • Analyser la faisabilit\u00e9, l'acceptabilit\u00e9 et les d\u00e9fis de l'impl\u00e9mentation du logiciel CAD dans le syst\u00e8me de sant\u00e9 guin\u00e9en.<\/li>\n
  • Estimer le co\u00fbt-efficacit\u00e9 du d\u00e9pistage de la tuberculose par le logiciel CAD par rapport aux m\u00e9thodes conventionnelles.<\/li>\n<\/ul>\n

     <\/strong><\/p>

    M\u00e9thode<\/strong><\/p>\n

    Une \u00e9tude mixte est en cours.  <\/p>\n

    Une \u00e9tude transversale est actuellement en cours pour calibrer le DAC (pour l'analyse des images radiographiques pulmonaires), en utilisant des tests bact\u00e9riologiques de r\u00e9f\u00e9rence tels que GeneXpert (et une \u00e9valuation clinique par des experts de la tuberculose) dans les CDTs de Conakry.<\/p>\n

    L'\u00e9tude a port\u00e9 sur des patients \u00e2g\u00e9s de 15 ans et plus pr\u00e9sentant des sympt\u00f4mes respiratoires et pouvant subir des examens radiologiques et bact\u00e9riologiques.<\/p>\n

    Une analyse de l'acceptabilit\u00e9 et de la faisabilit\u00e9 sera ensuite r\u00e9alis\u00e9e. Elle sera suivie d'une analyse co\u00fbt-efficacit\u00e9.<\/p>\n

    Progression :<\/strong><\/p>\n

    La collecte de donn\u00e9es est en cours. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
