| VIADSa facilitates the visualization of data sets to enhance understanding. |
“Pictorial and easy to read and understand huge data sets.” “VIADS presents a large data set containing diagnoses codes in an organized, intuitive graphical output with simple summary statistics that can be interpreted quickly and at a summary level, allowing for better understanding of the data set and how it can be analyzed.” “I think that VIADS would help with methodology, analysis, descriptive statistics, and presentation of results as well.”
|
| VIADS provides a comparison function that compares similar data sets and highlights the results. |
“Comparison of complex data sets would be easy with this type of visualization.” “It is nice to have comparison of data sets, but that also goes back to understanding what the data set consists of.” “By comparing different sets of data, it would help clarify if it is an important/relevant area to study.”
|
| The filtering function is a helpful means of reducing the size of data sets easily and effectively. |
“By being able to utilize large sets of data and recognize top percentages or number of certain topics, it helps you focus on an area to potentially study.“ “I think the VIADS system is really cool, and it’s fascinating how it operates. I would say that it’s a great tool with algorithms in place but can also be overwhelming sometimes if there is overabundance of data. What’s great is that we can reduce the amount of data displayed. I think the fine tuning of threshold can be tricky though and difficult if we don’t understand what CCb or NCc or CC + ratio means.”

| VIADS facilitates thought processes and hypothesis generation. |
“The many results and branches definitely help generate hypotheses. In the beginning, it is a little difficult since I would be focused on how to sort the data or minimize how many nodes/results are displayed, but after a while, with the key terms and diagnoses, it triggers my thought process so I think it could help with generating new ideas.” “VIADS answered many of the questions I had about the data set before using the tool. After using VIADS, I felt that some of my hypotheses would be valuable to pursue and some would not be as much. It also helped me build on some initial hypotheses to generate more specific and advanced questions.” “At least this session, the amount of diagnoses present and how it branches from one another helps not only stir up thoughts of known studies or information but helped me think of new ones or new questions that may not be answered yet.”

| Other useful features of VIADS |
“I think that VIADS is very useful because it is simple and has a specific purpose that it serves well. I have used ICD codes frequently in my work so far, and I think this type of specific tool would be helpful for many applications.” “I think the training session helps a lot, because if I were to navigate it on my own, I probably wouldn’t know what the branching from each category means and the nodes when I did a preview, but it helps to click around.” “The graphical output and ability to export the diagram would be very useful in presenting diagnosis data.”

| Suggestions |
“Not confident enough to base my hypothesis on numbers only.” “I think it could but then I would need training on how to create a data set to meet the VIADS system or how to set up complex data on a spreadsheet so when it’s uploaded to VIADS, it can help sort.” “Just that the buttons need to be adjusted...they don’t always ‘click’ unless you put your mouse on a very specific spot.”
