DireCT is a mobile application dedicated to ease the process of finding the perfect clinical trial for patients. In designing the interface, we wanted to make it simple and easy for patients to get clinical trial information without the need to go through cumbersome technical documents. Additionally, we wanted to take it a step further by creating an engaging experience where patients can also interact with the information. The following are key points we wanted to deliver in designing this application:
Engaging Interface – Specifically designed for the iPad along with the simplistic look and feel of the new iOS 7, the application provides an easy-to-use and engaging user interface. Instead of merely providing an informational application, DireCT allows patients to interact with the content through industry standard hand gestures for mobile devices. This not only facilitates easy navigation, but also leads to faster adoption.
Usability – DireCT is designed to help patients easily understand the information presented on the application by putting them into context. The application helps patients digest clinical trial information by dividing contents into easily identifiable sections, which can be used to navigate from one section to the next. Additionally, information icons are available to help patients understand the content of the application.
Personalized Experience – Patients will be able to create a user profile and set preferences, which can be used to filter clinical trials. Additionally, patients can create a watch list of clinical trials that they are interested in.
From this screen patients will be able to enter their personal data, health condition and history, as well as other information that are relevant in selecting a clinical trial to participate in. All the information in this section will be used to filter through clinical trials and create a short list of suggested clinical trials.
- Actionable Information – DireCT incorporates two features that allow users to act on readily available information. First, key metrics are included on the home page to provide patients with an up-to-date list of clinical trials. Second, alerts and notifications are incorporated to help patients keep track of their watched and submitted clinical trials, and new trial updates.
Keeping these elements in mind, we reorganized and divided the clinical trial information into the following elements:
Onboarding Screen – New patients are directed to the Onboarding screen after they launch the application for the first time. Patients can enter their basic information and upload a photo, as well select key words that will help generate a list of recommended clinical trials. Additionally, a quick tutorial is provided to familiarize patients with the hand gestures needed to navigate through the application.
Home Screen – A returning patient is directed to the Home Screen once the application is launched. From this screen, key metrics such as open, closed, and submitted trials are provided for the users to easily track changes to the clinical trial database. Patients can also tap on these metrics to view a filtered list of trials according to their selection. An icon precedes each trial to help patients easily differentiate between new and updated trials. On the right side of the app, a search feature is provided for patients to look for specific trials they may be interested in. The filters include key word(s), location, search radius, and an option to include closed trials. Patients can tap on the search button to display a list of the populated trials on the left side of the screen. From this list, patients are able to tap on any trial to drill down to more details.
The Roadmap – The Roadmap is a set of tabs that organizes and divides the information of a specific clinical trial into the easily accessible sections. This feature allows patients to keep track of where they are in the review process, as well as easily navigation from one section to another with a simple tap. The Roadmap sections are as follows:
a. Overview – From this section, patients can read through a summary of the clinical trial and decide whether they want to submit their profile for consideration. An abridged timeline is included at the bottom to provide patients with an overall picture of the experiment. Patients can click on the expand button to view a pop up of an expanded timeline that displays details including drug dosages, lab tests, etc.
From the expanded timeline view, patients can tap on a point on the timeline to display details corresponding to the event such as duration, time frame, tests, and labs to be performed. As patients scroll up and down to view information about other events, the point corresponding to the information displayed will be highlighted to provide context.
b. Eligibility – This section organizes the eligibility requirements into an easily understandable format. Age, Gender, Ethnicity, Genetic Mutation Type, and Biomarker requirements are displayed on the top to assist patients in quickly determining whether they are eligible for the trial or not. If a patient meets the basic requirements, they can proceed to review the inclusion and exclusion criteria.
The inclusion and exclusion criteria are displayed as interactive checklists to help patients determine their eligibility. For the inclusion criteria, a patient needs to tap each criterion to indicate eligibility, which will be marked with a solid blue circle. The application keeps count of selected criterion to ensure that a patient meets the requirements. On the other hand, a patient needs to tap and deselect each criterion on the list of exclusion criteria, which are selected and marked with a solid red circle by default. Requiring patients to do this ensures that each criterion is reviewed to prevent any adverse outcomes during the clinical trial.
c. Details – The top right of this section displays a set of slide out sliders for the different arms of the trial. Each arm can be tapped to display the corresponding arm type and label. The intervention type and names are displayed right below the arms with its description displayed on the right side as a carousel-cased slider, so patients can also swipe left to view details of the outcome measures such as the primary, secondary, and other pre-specified outcome measures. Scroll bars will appear on sections where there are more content to inform patients that they can swipe up or down to view more information.
d. Site/Contact – Patients can view a list of participating sites that host the selected clinical trial, as well as the names of investigators for the study if information is available. Additionally, a map view that shows the site locations gives patients a better visual presentation of this information. Sponsor information and central contact are also provided for patient reference.
e. Considerations – Patient considerations are organized and separated into three sections on a carousel-based slider. Patients can swipe left or right to view information on Risk of Study Participation, Benefit of Study Participation, Study Logistics, and Post Study Plans. Scroll bars will appear on sections where there are more content to inform patients that they can swipe up or down to view more information.
After patients review the details and requirements for the selected trial, they can tap on the submit button to send their profile for consideration or tap on Watch This Trial to add the selected trial to their watched list. Additionally, sharing capabilities through social media and email are provided so patients can recommend clinical trials to peers who may be eligible.
- Right Side Navigation – From this screen patients will be able to enter their personal data, health condition and history, as well as other information that are relevant in selecting a clinical trial to participate in. All the information in this section will be used to filter through clinical trials and create a short list of suggested clinical trials.
In conclusion, DireCT is a mobile application designed to optimize a patient’s user experience in two ways: First, by simplifying the way a patient views large amounts of clinical trial information, and second, by making both the information and the application interactive. Our goal is not only to provide Eli Lily with a well-designed clinical trial application for patients, but also to provide a foundation to build a future generation of patient-centric applications.
