VisualDx Plus DermExpert is available on both iOS and Android devices. You must have:

  • iOS mobile devices using 11.2 or later

No. The images never get sent back to VisualDx and are not saved on your mobile device. We improve our proprietary machine learning algorithm using the VisualDx image collection, or with publicly available images.

Yes. VisualDx and DermExpert do not collect any information that can be tied back to a specific patient. We also do not transmit or store any images from the mobile device.

DermExpert’s Lesion Model analyzes the image against a set of approximately 80 lesion types and returns a score for each lesion indicating the model’s confidence that the image is a match. The top 3 matches are shown to the user, who must then select a lesion type to continue. The selected lesion is then added to the workup as a finding, and the user continues through the workflow and answers questions about the lesion(s) and/or other symptoms to review results.

After the image is analyzed, it is deleted from the user’s device.

1. Select the camera or icon in the search bar to start. (Apple homepage shown on the left; Android homepage shown on the right.)

5. Answer a few questions.

6. See the results.

The VisualDx image collection has been carefully curated from an international community of medical experts. Notable collections from many individuals and institutions have become part of the broader VisualDx image collection. The majority of images in the collection have been professionally scanned from 35mm color transparencies (slides). Contributors retain their image rights and are given access to a library of their scanned images.

The VisualDx Start Page

The “select a problem area” option is a way for users, particularly users of our previous version, to quickly build a differential from common problem areas. It is not comprehensive of the breadth of VisualDx but instead serves as shortcuts for areas that have been requested by our users.

The search box allows you to access the full set of findings and diagnoses we have available while “select a problem area” represents a subset of commonly searched chief complaints. You can build the same differential through the search box that can be accessed through “select a problem area.”

To get started, type a symptom, medication, country, or diagnosis in the search box.

You can also click “select a problem area” to choose from particular pre-coordinated scenarios to build a differential without typing.



Using the Differential Builder

A required finding has two purposes in VisualDx:

  • It determines the workup questions, and
  • It limits differential results to only the diagnoses that contain the finding.
    • For example, if Fever and Rash are required (green) and Headache is optional (gray), the diagnoses you see in a differential will be required to have Fever and Rash, but may not contain Headache. However, any diagnoses that also have Headache will be ranked higher in the results than diagnoses that do not. Optional findings do not remove diagnoses from your differential.

At least one finding must be designated “required” to build a differential.

DDx Strength accounts for relevance of findings entered with respect to the diagnoses returned.

If you enter findings that were contradictory or unrelated to each other or enter generic findings that apply to many diagnoses, such as malaise, the differential strength will be poor. A high DDx Strength indicates that the findings you entered differentiate a handful of diagnoses from the ~3000 available and the set of findings entered seem highly correlated, such as your top match level is 5 out of 5 versus 3 out of 5 findings.

VisualDx medical staff work across specialties to develop the questions provided in every work-up. That means that depending on the required finding you enter, you may see different questions based on what is relevant for that finding. If you want to enter particular findings, you can use the Additional Findings typeahead.



Differential Results

Para melhorar o desempenho do VisualDx, os resultados são truncados para 150 diagnósticos.

O objetivo do Filtro em VisualDx é filtrar diagnósticos que podem não fazer sentido para o seu paciente. Portanto, o Filtro só aparece quando seus resultados diferenciais contêm diagnósticos que podem ser filtrados. Isso inclui diagnósticos que contêm exposição química / bio / rad / nuclear, viagem, reação a medicamentos, picadas e picadas e exposição marinha.

NOTA:  Se você inserir uma descoberta diretamente que se enquadre em uma dessas categorias, essa categoria não aparecerá nas opções de filtro. Por exemplo, se você inserir “Gana” como uma descoberta, Viagem não será selecionável nas opções de Filtro. Para remover essa descoberta, volte para o construtor diferencial e edite as descobertas.
