VisualDx Overview

Overview

VisualDx is a diagnostic decision support system designed by clinicians to aid medical professionals in the diagnosis of visually identifiable diseases. It provides instant access to specialist knowledge at the point of care, merging medical images with concise clinical text. As the clinician enters actual patient findings, VisualDx creates a differential diagnosis of visually identifiable diseases, drug reactions, and infections. VisualDx is a multi-use tool designed for day-to-day clinical diagnosis, emergency preparedness, and medical education.

Benefits

What Does It Do?

As a visual clinical decision support tool, VisualDx uses specific patient data to develop a visual differential diagnosis. The clinician enters patient symptoms and other clinical findings, such as lesion type, body location, medical history, medications, etc. With each entry, the system builds and refines the differential, never eliminating a diagnostic possibility but ranking each one by relevance to the patient findings. VisualDx displays images and key clinical information on all relevant diagnoses for a quick side-by-side comparison to the patient.

VisualDx is organized to match the way a doctor thinks about symptoms and diagnoses. The tool presents multiple images of each disease, showing the condition at different stages and in people of different ages and skin types. In addition, VisualDx facilitates rapid access to condition-specific, actionable clinical information and insight from physician experts, including the following:

How It Is Organized

VisualDx is problem oriented and context driven. Rather than being indexed alphabetically or by pathophysiology, diagnoses are viewed in the context of patient particulars, such as by age, immune status, lesion distribution, and so forth.

Users can choose the clinical scenario, or medical context, that best matches the patient's presenting problem. Diagnoses often appear in more than one clinical scenario, a redundancy built into the tool for greater diagnostic efficacy. This overlapping organization provides for accurate differential diagnoses even when your entry point into VisualDx does not entirely match the patient's chief complaint.

How to Use VisualDx

There are two ways to use VisualDx: build a differential diagnosis and search for and view specific diagnoses.

To build a differential diagnosis:

  1. Enter a clinical scenario. You must first choose a clinical scenario. On the VisualDx home page, click the Differential Builder button and click the clinical scenario most appropriate to your presenting patient. If you need assistance selecting a clinical scenario, click the Guide My Selection button (in the upper-right portion of the screen) and follow the steps in the wizard.
  2. Enter findings. After entering the clinical scenario, enter findings in the upper-left portion of the screen. One option is to click the Quick Start button, which takes you through a series of guided steps for entering findings. For alternative methods, see below. Note: The order in which findings are entered does not impact the final match results. All methods are optional.
  3. Matches view, List view and Compare view. Compare and contrast your patient's findings with potential diagnoses using the view modes in VisualDx: Matches view, List view and Compare view. Note: In Matches view, image stacks are displayed for all diagnoses that match an entered finding. In Compare view, only those diagnoses that you specifically select to compare are displayed. In List view, all the diagnoses in a clinical scenario are listed.
  4. View images. Navigate through image stacks and compare images to your patient using the forward and back navigations buttons for each stack.
  5. Read clinical diagnostic text. On an image stack, click the diagnosis name link to read concise, clinically useful diagnostic information about a diagnosis in the Diagnosis Text and Images view. Additionally, you may simply click a diagnosis name in the List view to link to the information on the Diagnosis Text and Images view.
  6. Update and refine. Reset or refine your search findings (if needed) by adding new findings (as discussed in step 2) and/or removing findings by either clicking the Clear All button or by removing them individually.

To search for a specific diagnosis:

  1. VisualDx Search. In the VisualDx Search box, type a diagnosis name, finding, or other related phrase and press Enter. (As you type, a list of diagnoses with similar wording will appear for your convenience. However, you are not required to select one.)
  2. Explore your results. A search yields results sorted by relevance to your search terms. Scroll down the page and view the results.
  3. Make your selection. Choose the result that most closely matches your patient. Note: The search algorithm will select a clinical scenario based on what your search terms are. You can direct your results toward a particular clinical scenario by including words from the scenario name in your search (eg, child, adult, or immunocompromised). Click the diagnosis name you are interested in, and it will take to you the appropriate Diagnosis Text and Images page.

All Images View

The All Images view displays medium-size versions of all of the images within an individual diagnosis at once.

How do I use the All Images view?

There are multiple ways to display the All Images view. When on the Differential Builder page, images stacks have an All Images link. When in an individual diagnosis, click the All Images link in the upper-right corner of the screen.

If there are more images in the stack than fit on a page, use the vertical scroll bar to scroll down through the rest of the images.

To return to Diagnosis Text and Images view, click the Text and Images link or any of the links under the Contents section.

How do I view a large-size version of an image on the All Images view?

Simply click any image to view it at its largest size.

Add Body Location Button / Window

Clicking the Add Body Location button opens the Body Location window, which allows you to select body locations and/or distributions. You can select a general body area or a more specific location within an area. At least two main areas comprise the window: a human figure and a list of body locations. Additionally, there may be a list of distributions that include more than one body location. Rolling over body locations or distributions (where applicable) highlights the associated areas on the human figure. In most clinical scenarios, the gender is set to Male by default. You may toggle between Male and Female options. Clicking the Cancel button will not save your changes, but clicking the OK button will.

How do I add a specific body location as a finding?

You can select a specific body location in one of two ways:

How do I add a distribution as a finding?

Under the Distributions heading, click the appropriate distribution.

Scrolling over each distribution will display highlighted areas on the human figure that visually illustrate the distribution.

Note: This option is not available in all clinical scenarios.

How do I enter the finding(s) and return to the clinical scenario?

Once you have entered the appropriate body locations, click the OK button.

How do I exit without adding any findings?

To exit the Body Location window without adding any findings, click the Cancel button or the Close (X) button in the upper-right portion of the window (not on the browser window or tab itself).

Add Distribution Button / Window

Clicking the Distribution button opens the Distribution window, which allows you to select a particular body distribution. The window displays illustrations of a particular body location with its associated distributions highlighted. Rolling over each will further highlight the areas of the illustrations that visually demonstrate the distribution.

How do I add a distribution as a finding?

Click the distribution you would like to add as a finding, and then the distribution will be added to the Current Findings section.

How do I exit without adding a distribution?

To exit the Distribution window without adding a distribution, click the Close (X) button in the upper-right portion of the window (not on the browser window or tab itself).

Add Key Findings Button / Window

Within a clinical scenario, clicking the Add Key Findings button opens the Key Findings window, which allows you to answer questions relevant to the specific clinical scenario and add findings in a simple manner. Questions may have to do with timing, appearance, presence or lack of fever, the presence or lack of pain or itch, etc. This is an easy way to enter findings in the Current Findings section.

How do I answer Key Findings questions to add findings?

Some key findings are displayed as radio buttons (meaning you can select one option) or check boxes (meaning you can check as many check boxes as are applicable to your patient). Click the OK button to add the key findings to the Current Findings section.

How do I exit without adding any findings?

To exit the Key Findings window without adding any findings, click the Cancel button or the Close (X) button in the upper-right portion of the window (not on the browser window or tab itself).

Add Lesion Type Button / Window

Clicking the Add Lesion Type button opens the Lesion Type window, which allows you to select a lesion type. Some lesion types expand to show more specific types within the larger category. Rolling over certain lesion types may illustrate lesion characteristics (eg, blanching under pressure from a thumb). Once you select the lesion type, it is added to the Current Findings section.

How do I add a lesion type as a finding?

Click one of the general lesion types (ie, Scaly Papule/Plaque, Purpura/Petechiae, Erosion/Ulcer/Atrophy, Smooth Papule/Plaque, Flat/Macular, Erythema/Erythroderma, Vesicular/Pustular), and then click the appropriate specific lesion type.

How do I exit without adding any findings?

To exit the Add Lesion Type window without adding a lesion type, click the Close (X) button in the upper-right portion of the window (not on the browser window or tab itself).

Browse All Findings

The Browse All Findings button is one way to enter patient findings. This tool contains several lists of findings that are pertinent to the current VisualDx clinical scenario. These lists include symptoms, signs, appearance, medical history, medications, occupations, travel, etc. Each list is further broken down as applicable to the clinical scenario.

How do I use the Browse All Findings tool?

Within a clinical scenario, in the left portion of the screen, under the Refine Differential heading, click the Browse All Findings button. A list of findings and/or finding categories appears.

Finding categories that contain a group of findings are indicated by a right-pointing arrow on the right edge of the item. Click a category to explore the list of findings that it contains. Findings themselves do not have a right arrow. Click an item to add the finding relevant to your patient. VisualDx will do the following:

To enter more than one finding for your patient, simply repeat the above instructions.

TIP: Start with findings that seem to be most relevant to your patient's condition. Look through the Browse All Findings categories to discover other relevant findings.

Change Clinical Scenario

The Change Clinical Scenario link can be found on the left-hand side of the screen on the Differential Builder page. This pop-up menu allows you to switch directly from one scenario to another, chosen from the list of all possible clinical scenarios.

When on the Differential Builder page, the pop-up menu displays a full but miniature version of the Choose a Clinical Scenario page, listing all of the clinical scenarios in VisualDx.

Switching clinical scenarios preserves any previously entered findings. In the new clinical scenario you select, Matches view is displayed with image stacks sorted by matches to the currently entered findings. Any previously entered findings that do not appear in the new clinical scenario will be disabled and display as grayed-out in the Current Findings section.

Choose a Clinical Scenario

On the VisualDx home page, clicking the Differential Builder button takes you to a screen that displays all of the clinical scenarios, organized by age (neonate, child, adult, and elder) and specialized content. Find the clinical scenario that is most applicable to your patient, and click the link.

Clear All Button

Within a clinical scenario, on the Differential Builder page, in the Current Findings section, there is a Clear All button. To clear all findings from the Current Findings section at one time, click the Clear All button.

Note: If you only want to clear some findings from the Current Findings section, click the to the right of the finding(s) you want to remove.

Clinical Scenarios

The term clinical scenario describes a collection of diagnoses in VisualDx that form the basis of an overarching differential diagnosis, such as Adult - Single Lesion or Growth, Adult - Immunocompromised, Adult - Female Anogenital, Child - Multiple Lesions or Rash, etc. The information presented within a clinical scenario is tailored to the particular area covered by the scenario. For example, in the Adult - Immunocompromised clinical scenario, the text and images provide information that specifically applies to the immunocompromised patient. This design allows VisualDx to initiate a unique differential diagnosis right from the start.

How do I access (get into) a clinical scenario?

There are multiple ways to get into a clinical scenario. There is a wizard available (click the Guide My Selection button) if you are unsure of which clinical scenario to enter, or you can go right into a clinical scenario by clicking the scenario name. Additionally, if you have a diagnosis in mind or associated findings, you can use the search tool (VisualDx Search box), which will yield results that, when clicked, will bring you directly into a Diagnosis Text and Images page within a specific clinical scenario.

How do I enter a clinical scenario via the most direct route?

On the VisualDx home page, clicking the Differential Builder button takes you to a screen that displays all of the clinical scenarios, organized by age (neonate, child, adult, and elder) and specialized content. Find the clinical scenario name that is most applicable to your patient, and click the link.

What if I cannot decide what clinical scenario is best to enter?

To those who are new to VisualDx or may be having a hard time deciding which clinical scenario is most appropriate, on the Choose a Clinical Scenario page, clicking the Guide My Selection button takes you through questions that, when answered specific to your patient, will launch the appropriate clinical scenario based on the selection(s) you made.

Clicking the Guide My Selection button opens the clinical scenario selection wizard. The wizard starts with three questions and, depending on how you answer, the result will be either a Go Into Clinical Scenario button that, when clicked, takes you to the appropriate clinical scenario or a Next button that, when clicked, prompts the wizard to offer more questions.

Compare View

In Compare view, only selected diagnoses are displayed. Therefore, to view diagnoses in Compare view, you must have already selected at least one diagnosis from the Matches view or List view. Compare view displays rows of medium-size image stacks of the selected diagnoses. The total number of selected diagnoses is displayed in parentheses on the Compare view link itself (eg, "Compare (6)"). This is helpful to note because the number of diagnoses selected often exceeds the viewable screen area, so this number is one indication that it may be necessary to scroll down through the remaining diagnoses to view them all (in addition to the enabled scroll bar).

TIP: If you click the Compare view tab and there are no images on the screen, you will need to select at least one diagnosis from the List view.

How do I select (highlight) diagnoses?

To select diagnoses for viewing in Compare view, either:

How do I deselect diagnoses?

To remove (deselect) diagnoses from Compare view, either:

How do I change the sort order of the diagnoses in Compare view?

To change the sort order of the diagnoses to display emergencies, click and check the Show [E] Emergencies First checkbox. Any selected emergency diagnoses will move to the top of the Compare view. To return to the default order of viewing click and uncheck the Show [E] Emergencies First checkbox.

How do I know if I am in Compare view?

When you are in Compare view, VisualDx displays rows of medium-size image stacks and only those diagnoses you have selected. Additionally, when in Compare view, the Compare view link will be bold and black and lose its underline indicating that the view is already active and Matches and List view links will be underlined.

How do I switch back to Matches view?

To return to Matches view or List view, click the Matches view or List view links in the upper-right corner of the Differential Builder page.

Current Findings Section

The Current Findings section lists all of the findings that have been selected with any of the findings entry tools. The Current Findings section is only visible when at least one finding has been entered.

When you delete a finding, the List view and the display of matching diagnosis image stacks are updated accordingly.

How do I remove all findings from the Current Findings section?

To remove all items from the Current Findings section at once, click the Clear All button.

How do I clear just some of the findings I have entered?

To clear only some of the findings you have entered, in the Current Findings section, click the to the right of the finding you want to remove.

Diagnosis Alerts and Notices Quick Links

In the Diagnosis Text and Images view, in the left column of the screen, VisualDx has provided the option to include customized report and alert quick links. This feature can promote increased awareness about notifiable diseases or specific instructions for processing conditions as applicable to that diagnosis. The Alerts and Notices quick links are visible to users at all times, regardless of where they have scrolled within the page. Clicking these links will open informative content in a new browser window. Content may consist of documents, PDFs, Web pages, and other multi-media formats.

Diagnosis Contents Links

Each Diagnosis Text and Images view contains textual information on a diagnosis, organized into the following categories:

The sections are displayed in the above order. To quickly skip to one particular section, you may click the corresponding link in the Contents.

On the menu bar of every screen of VisualDx, clicking the VisualDx logo takes you back to the VisualDx home page.

Note: If you go to the VisualDx home page in error and/or want to return to a previous clinical scenario and its corresponding entered findings, click the browser's Back button.

Image Navigation Buttons

In any image stack, you are able to navigate through all images corresponding to a diagnosis by using the navigation buttons, Forward and Back.

How do I navigate through the small image stacks?

Within any clinical scenario, there are image stacks displayed that are small-size versions of the top image in the image stack for each diagnosis. The navigation buttons are on each side of the lower portion of the image stack. Click the Forward button (right-pointing arrow) to navigate forward through the stack. Click the Back button (left-pointing arrow) to navigate backward through the stack.

How do I scroll through images on the Large Image screen?

While still in Large Image view, click either of the navigation buttons, which are on each side of the lower portion of the image stack. Click the Forward button (right-pointing arrow) to navigate forward through the stack. Click the Back button (left-pointing arrow) to navigate backward through the stack. In addition, on the Large Imagepage there is a slider bar that will change the image as you slide it right and left.

Image Stacks

Images for each diagnosis are arranged in stacks, with the image of highest relevance (matches to current findings) displayed at the "top" of the stack, which means it is displayed first in the stack and is visible without needing to click to navigate through images. At the top of the image stack is the diagnosis name (which is a link that, when clicked, takes you to the Diagnosis Text and Images view). The bottom of the image stack has a link to the All Images view that also includes the number of images available for the current diagnosis. Image stacks have three sizes: small, medium, and large.

Where are image stacks used?

Small-size image stacks are found on the Differential Builder page, in the Matches view.

Medium-size image stacks are found on the Differential Builder page, in the Compare view .

The large image stack is found on the Large Image page. To view this page, click the Large Image button (magnifying glass in upper-right corner) in any image, or click the image itself.

How can I see other images in the stack, one at a time?

All image stacks have navigation buttons, which can be found on each side of the lower portion of the stack, to navigate forward and backward through the image stack. If you go forward beyond the last image in the stack, you cycle back to the beginning of the stack. If you go back before the first image, you cycle to the end of the stack.

How can I view all images within a stack at once rather than scroll through one at a time?

The All Images view displays medium-size versions of all of the images within an individual diagnosis at once. The All Images (#) link is located in the upper-right corner of the page when you are in an individual diagnosis.

When on the Differential Builder page, to view all the images in a stack at once, click the All Images (#) link at the bottom of the stack.

Large Image View

The Large Image view contains a stack of the largest images in VisualDx. The page is labeled with the diagnosis name and contains some image navigation controls at the bottom.

How do I view an image at its largest size?

On the Differential Builder page, the Diagnosis Text and Images view, or the All Images view, click the Large Image button (magnifying glass in upper-right corner), or click the image itself.

How can I view other images in the stack at their largest size, one at a time?

To view the other images in the stack, while still in the Large Image view, click either of the navigation buttons, Forward or Back or use the slider at the bottom of the screen.

The Forward button will navigate you forward through the stack, and the Back button will navigate you backward through the stack.

How do I print a large image?

To print a single large image, when on the Large Image view, click Print on the menu bar.

How do I view all parts of an image if the image itself is too large for my screen?

When a large version of an image is larger than your available screen area (ie, your screen resolution is smaller than the size of the image) or your browser window has been scaled down by choice, the cursor changes, and clicking and dragging the image will move it. While you will not be able to see the full image on the screen all at once, you will be able to click and drag to see all parts as necessary.

Note: Increasing your screen resolution to greater than 1024x768 will allow you to view the full large screen image without needing to click and drag.

List View

The List view lists all the diagnoses within a VisualDx clinical scenario and the number and type of currently selected findings that match each diagnosis.

As you select findings relevant to your patient the List view is updated and resorted.

Note: Emergency and potentially life-threatening diagnoses requiring immediate attention are preceded by [E].

Diagnoses are sorted in the list box in one of two ways:

How do I change the sort in the List view?

See Show [E] Emergencies First Sort

How do I select diagnoses from the List view to compare?

Click the check box corresponding to the diagnoses you would like to select. Click the Compare view link to visually compare those hand-selected diagnoses side by side.

How do I deselect diagnoses from the Diagnoses list box to compare?

Click the individual check boxes corresponding to the diagnosis names to deselect the selected diagnoses.

VisualDx Search

How do I use the tool to search for a specific diagnosis?

Click in the VisualDx Search box and type a term. As you type, a list box displays diagnosis names that match what is being typed. If you see the diagnosis name you are searching for, you may click it to complete a search on that exact term. You may also type a term and either press Enter or click the Search button to execute your search.

Note: If no names display in the list box as you type, it does not necessarily mean you will not get search results; it simply means the term typed does not match a diagnosis name exactly. Results that do not match an exact diagnosis name may still match a finding name or a term within a diagnosis text.

How do I use the tool to search for a finding or term within a diagnosis write-up?

Like entering a diagnosis name in the VisualDx Search box, you may search for a finding or term associated with any diagnoses in VisualDx. Click in the VisualDx Search box and begin typing a finding or other term. As you type, a list box displays diagnosis names that match what is being typed. Because you are not looking for a diagnosis name but rather a finding or other applicable term, type the text in full and then either click the Search button or press Enter.

What do search results yield?

On the search results page, you will see each diagnosis that returned a result, whether the search term matched a diagnosis name, finding, or content from a diagnosis text. Entering a common diagnosis name, finding, or other term will yield many results, and it will be necessary to scroll down the page to view them all.

How do I get to the Differential Builder page so I can see the rest of the diagnoses in the clinical scenario?

On the Diagnosis Text and Images view, click the Differential Builder button in the menu bar to go to the clinical scenario containing your chosen diagnosis.

Matching Findings Sort

On each Differential Builder page within a clinical scenario, diagnoses are sorted by the number of matching findings, then by clinical importance and commonality in North America (very common and/or clinically important, common, uncommon, or extremely rare), as assessed by VisualDx senior-level editors, and finally by alphabetical ordering.*

* Note: If the matching findings include a medication, diagnoses in the result set may also be sorted according to the number of literature citations documenting the disease-drug association. Specifically:

How do I switch the Sort to view all emergency diagnoses within a clinical scenario rather than by Matching Findings?

See Show [E] Emergencies First Sort.

Matches view

Matches view is a way of viewing the differential diagnosis for the findings you have entered. Diagnoses matching the current findings are displayed as image stacks. Image stacks with a greater number of matches are displayed at the top of the page. Horizontal banners indicate the difference in number of matches.

Note: Diagnoses matching current findings means that diagnoses that match one or more findings you enter by clicking the Add Lesion Type, Add Body Location, or Add Key Findings buttons; by choosing findings from the Browse All Findings tool; or by using the Type to Add Findings box.

TIP: If there are no diagnoses displayed on the Matches view, you will need to enter findings.

How do I clear all the matching diagnoses?

To clear all the findings and, thus, matching diagnoses, in the Current Findings section, click the Clear All button.

How do I clear just some of the findings I have entered?

To clear only some of the findings you have entered, in the Current Findings section, click the to the right of the finding you want to remove.

How do I change the sort order of the diagnoses in Matches view?

See Show [E] Emergencies First.

How do I know if I am in Matches view?

When you are in Matches view, VisualDx displays rows of small-size image stacks, separated into groups of diagnoses with the same number of matching findings. There will be a banner for each group inidcating how many diagnoses are in the group and the number of matching findings for the group (eg, 17 diagnosis match 3 of 4 current findings). Additionally, when in Matches view, the Matches view link will be bold and black and lose its underline indicating that the view is already active and Compare and List view links will be underlined.

How do I switch to List view?

To switch to List view, click the List view link in the upper-right corner of the page.

How do I switch to Compare view?

To switch to Compare view, click the Compare view link in the upper-right corner of the page.

Print Button

In the VisualDx menu bar, on certain pages, clicking Print opens a print dialog box that allows you to print a copy of the information you are currently viewing. Clicking the Print button in the print dialog box prints the page according to the options selected.

Note: It is recommended that you use the VisualDx Print button rather than your browser's Print button.

Quick Start Button

On the Differential Builder page in the Matches view, the Quick Start button takes you through a series of steps for entering findings, starting with Add Lesion Type, Add Body Location (body location and/or distribution) or Add Distribution, and, when applicable, Add Key Findings.

Clicking the Quick Start button opens the Add Lesion Type window. Once a lesion type is selected, other questions appropriate for the clinical scenario will automatically be presented. After each step, click the OK button to add all applicable findings. Additionally, the image stacks on the Matches view and diagnoses in the List view are sorted accordingly.

Search Button

If you have a diagnosis name or finding in mind that you specifically want to search for, you can use the VisualDx Search. The Search button is the button to the right of the VisualDx Search box, and clicking it is one way to initiate a search.

Share Button

You may share a page in VisualDx, including a differential you have built, with anyone with a valid e-mail address. In the menu bar of every screen of VisualDx, clicking Share will display a Share This Page dialog box. Enter the recipient's name, recipient's e-mail, your name, and your e-mail. Click the Send button to send the link.

Show [E] Emergencies First Sort

When building a differential diagnosis, VisualDx normally shows the diagnoses with the most matches to the entered findings at the top of the display. Sometimes it is important to rule out emergency and life-threatening conditions as quickly as possible. VisualDx supports this need by allowing you to sort the diagnoses in the differential into Emergency and Non-Emergency diagnoses so that you may consider diagnoses requiring immediate attention first.

How can I best view all emergency diagnoses within a clinical scenario in one place?

To view diagnoses requiring immediate attention (e.g., potentially life-threatening) at the top of the Matches or List views, click and check the Show [E] Emergencies First checkbox. To return to the normal sorting, uncheck the checkbox.

Spread View

See the All Images view topic.

Type to Add Findings Box

The Type to Add Findings box is used to manually enter patient findings. Any type of findings may be entered, including those that may be entered with the other findings entry methods.

How do I use the Type to Add Findings box to enter findings?

Begin typing a finding in the Type to Add Findings box. Findings that begin with the letter or string of letters you type will be displayed. Use the Tab key, the Up or Down arrow keys, or your mouse to highlight the finding you would like to enter. Press the Enter key or click the finding to select it.

VisualDx will do the following:

Repeat the above instructions for as many findings as you would like to add to the Current Findings section.
