*The Problem
*Studies show that side effects of drugs and drug interactions are responsible for 7% of hospital admissions
*When left alone, very serious complications can develop, and adverse drug reactions (ADRs) can account for an unexpectedly large percentage of patient deaths
*Patients need all the tools they can get to help them research their own health problems, as the medical industry isn’t always able to catch problems before serious complications occur
*Existing solutions
*Most common style– enter medications, and look at any problems that interactions between the medications could cause
*This example comes from the AARP website
*Does not allow for user profiles and thus can’t check for personalized symptoms and risks
*Existing Solutions
*Rxplore, created by Dr. Jon Duke, is most similar to our product*Allows doctors to check the probability of a patient’s symptoms being caused by a prescription regimen*We intend to make our product more for the patients, rather than doctors
*Our Solution
*A model to predict how likely it is that a user’s symptoms are caused by medications or drug interactions
*Based on personalized medical history
*Account creation allows users to change their medications without having to re-enter information
*The Product
*Simplicity is key
*Once an account has been established, the only two screens a user interacts with are the log-in page and the dashboard
*Screenshots
First page a user encounters– log in or create an account
Users create an account by entering all required fields
Dashboard
*Includes an option to log out, a table of symptoms, and an easy-to-update list of medications
*Table consists of symptom name, drug that could be causing it, and probability that the symptom and medication are related
*Usability Tests
*Three tasks related to the same fictional person
*Testing the functionality and aesthetic appeal of the product, as well as the ease with which users can complete common tasks
*Tasks included creating an account, adding medications, searching for symptoms, changing medications, and finding probabilities associated with symptoms
*Pre/Post-Test Questionnaire
*Pre-test Questionnaire: General questions about the user’s age, gender, experience with technology/the internet, and whether the user takes medications
*Post-test Questionnaire: Several questions related to the aesthetic appeal and the ease with which the tasks were performed, rated from 1 (high) to 7 (low).
*Would you use this product if it were released to the public?
*Results
*Common suggestions:
*Use brand names for medications
*Redesign product so that less scrolling is required
*Organize symptoms more efficiently/allow the user to personalize symptoms that may be in the list
*Future Plans for Functionality
*This product can be further developed
*Coming back to our original goals, we would like the user to have a very personal experience using this product
*Users should be able to search for symptoms, or at least personalize the order in which symptoms are listed
*Symptoms that are related to drug interactions or allergies and chronic illnesses should also be included, on a personalized level
*Expand database of medications
*Future Plans for Site Design
*Allow users to submit feedback
*Users should be given a point of contact to whom they can submit any complaints, problems, questions, suggestions or positive comments
*Allow users to filter symptoms after adding a medication
*Acknowledgements
*We would like to thank our usability test subjects, Professor Shneiderman and Tak Yeon Lee, and, most of all, our wonderful mentors:
*Dr. Dean Sitting- University of Texas
*Dr. Allison McCoy- University of Texas
*Dr. Adam Wright- Clinical Decision Support Consortium
*Additionally, we would like to thank Dr. Jon Duke of the Regenstrief Institute of Indiana University for providing us with data on drug interactions for our database.
