Mesure de gravité
Bien que la mesure de gravité soit une façon courante de désigner les résultats générés par le dispositif, gardez à l'esprit que ce que le dispositif produit, ce sont des données quantifiables sur l'intensité, le nombre et l'étendue des signes cliniques tels que l'érythème, la desquamation et l'induration, entre autres.
En effet, les professionnels de la santé et les organisations peuvent utiliser les données générées par le dispositif pour déterminer dans quelle mesure un patient est affecté, mais ce que le dispositif lui-même génère n'est pas la gravité. Ceci est signalé de manière appropriée dans les résultats que génère le dispositif, ce qui est conforme à la norme FHIR lorsqu'on remarque que les résultats générés constituent un DiagnosticReport, avec le statut preliminary.
Exemples illustratifs
Les blocs JSON de cette page sont des exemples de réponses, fournis pour montrer la structure des données que le dispositif renvoie. Les valeurs qu'ils contiennent, y compris celles de l'objet metrics, sont des exemples. Elles ne constituent pas des déclarations de performance du dispositif et ne doivent pas être interprétées comme des revendications de performance.

Demande du corps
Si vous devez analyser une image dont l'affection connue est la dermatite atopique, vous pouvez envoyer une demande de suivi à l'API.
Un exemple du corps de la demande peut être le suivant :

Voici la description des propriétés pertinentes de la demande du corps :
bodySiteest le code de la zone du corps qui identifie la zone où l'image a été prise. La liste des codes admis est fournie par Legit.Health sur demande à l'adresse support@legit.health.knownConditionForThisImageest défini sur le codeAtopic dermatitis, de sorte que l'API exécutera les algorithmes spécifiques liés à cette pathologie.previousMedian'est pas obligatoire. Il s'agit d'un tableau présentant un ensemble des images antérieures de l'affection analysée. Les algorithmes dotés de l'IA utilisent ces informations pour calculer le rapport final.scoringSystemsest un tableau présentant les systèmes de notation à calculer. Pour la dermatite atopique, nous prenons en charge :ASCORAD_LOCAL, la version automatique du SCORAD. Voir ASCORAD.SCORAD_LOCAL, le système de notation SCORAD calculé au niveau local.DLQI.
questionnaireResponse. Voir section suivante
Comment remplir questionnaireResponse
La propriété questionnaireResponse doit contenir toutes les réponses obligatoires à chaque système de notation spécifié dans la propriété scoringSystems.
Par exemple, si vous souhaitez que l'API calcule le DLQI, les réponses au questionnaire [« DLQI »] doivent contenir les dix valeurs correspondant aux dix questions du DLQI.
Questionnaires pour les systèmes de notation
L'extrait suivant contient les questionnaires de chaque système de notation disponible pour Atopic Dermatitis. Pour que le dispositif calcule l'un d'entre eux, vous devez obtenir les réponses requises auprès du patient ou du praticien.

Version 2.1
Qu'est-ce qui a changé ?
Rien n'a changé en ce qui concerne la mesure de gravité. Le seul changement est que, pour la fonction d'aide au diagnostic, vous pouvez désormais envoyer plusieurs images de la même lésion.
