Medida de gravedad
Aunque el término medida de gravedad es una forma habitual de referirse a la salida del dispositivo, ten en cuenta que lo que el dispositivo produce son datos cuantitativos sobre la intensidad, cantidad y extensión de signos clínicos como eritema, descamación e induración, entre otros.
En efecto, los profesionales de la salud y las organizaciones pueden utilizar los datos que produce el dispositivo para determinar en qué medida está afectado un paciente, pero lo que el propio dispositivo produce no es la gravedad. Esto se indica de forma apropiada en la salida del dispositivo, que sigue el estándar FHIR al señalar que la salida es un DiagnosticReport, con un estado preliminary.
Ejemplos ilustrativos
Los bloques JSON de esta página son respuestas de ejemplo con carácter ilustrativo, incluidas para mostrar la forma de los datos que devuelve el dispositivo. Los valores que contienen, incluidos los valores del objeto metrics, son ejemplos. No constituyen declaraciones sobre el rendimiento del dispositivo y no deben interpretarse como afirmaciones de rendimiento.

Esta es la descripción de las propiedades relevantes del body de la solicitud:
bodySitees el código de localización corporal que identifica la zona donde se tomó la fotografía. Legit.Health proporciona la lista de códigos admitidos previa solicitud a través de support@legit.health.knownConditionForThisImagese establece con el códigoAtopic dermatitis, de modo que la API ejecutará los algoritmos específicos relacionados con esta patología.previousMediano es obligatorio. Es un array con un conjunto de las imágenes previas de la condición analizada. Los algoritmos de IA utilizan esta información para calcular el informe final.scoringSystemses un array con los sistemas de puntuación que se van a calcular. Para la dermatitis atópica admitimos:ASCORAD_LOCAL, la versión automática del SCORAD. Véase ASCORAD.SCORAD_LOCAL, el sistema de puntuación SCORAD calculado a nivel local.DLQI.
questionnaireResponse. Véase la sección siguiente
Cómo rellenar questionnaireResponse
La propiedad questionnaireResponse debe contener todas las respuestas obligatorias de cada sistema de puntuación especificado en la propiedad scoringSystems.
Por ejemplo, si quieres que la API calcule el DLQI, questionnaireResponse["DLQI"] debe contener los diez valores correspondientes a las diez preguntas que tiene el DLQI.
Cuestionarios de los sistemas de puntuación
El siguiente fragmento contiene los cuestionarios de cada sistema de puntuación disponible para Atopic Dermatitis. Para que el dispositivo calcule uno de ellos, debes obtener del paciente o del profesional las respuestas requeridas.

Versión 2.1
¿Qué ha cambiado?
No ha cambiado nada en lo que respecta a la medida de gravedad. El único cambio es que, para la funcionalidad de soporte diagnóstico, ahora puedes enviar varias imágenes de la misma lesión.

Body de la solicitud
La interacción con la API es la misma que en la versión 2.0.
Respuesta
La respuesta se ha actualizado, aunque principalmente en cuanto a la información proporcionada. En concreto, la versión 2.1 no incluye detalles de soporte diagnóstico en la salida. La respuesta que se muestra a continuación es un ejemplo ilustrativo: los valores que contiene, incluidos los valores del objeto metrics, son ejemplos y no declaraciones sobre el rendimiento del dispositivo.
