Clinic Alert Notification Setup for Cardiac Device 

This is a sponsored course group project. In order to maintain confidentiality, specific details regarding the sponsor's company have been withheld. (The visuals you see on this page are coming from the final usability test report. It is for showcasing my research reporting ability.)

Background and Goal

The sponsor's clinical alert notification setup interface was currently undergoing a redesign to fix user flow issues. The new UI has not yet undergone usability testing and is not available publically.

 

Our usability tests for clinic alert notification setup were conducted from April 8-18 with a total of 9 participants, ranging in age from 20 to 64,  both with and without medical experience. 

​

The goal of the study is to evaluate the design of the clinic alert notification setup for cardiac devices to identify usability issues and provide improvement recommendations.

Usability Issue

  • Confusion with terminology 

  • Navigational challenges within what was perceived to be a very busy interface

  • Struggles in locating task actions due to lack of visual distinction between elements or too-small elements

Top Priority Fixes

  • Create stronger visual distinctions to emphasize important actions across the interface

  • Reconsider naming of Communication Preferences and structure of tabs in the panel

  • Include a link to the CareLink Notification Setup overview on the Manage My Clinic homepage

  • Try to simplify the interface by reducing the number of header menus

  • Consider a more universal search functionality

  • Ensure the UI design meets accessibility standards by increasing font size and creating enough contrast against the background

Limitation & Solution

  • Although the majority of our participants were healthcare workers, none of them had experience with the sponsor's products or other cardiac devices. 

  • Suggest conducting further internal usability testing with cardiac nurses and device technicians who are more familiar with the workflow and terminology, as they may provide more informed feedback.

My Learning

  • Usability tests are effective at uncovering a range of issues, from minor annoyances to major obstacles that could impede user satisfaction and performance.

  • Usability tests can show which parts of the user interface are effective and which are not, including buttons, menus, links, and content layout.

  • Usability tests can help prioritize feature development, bug fixes, and enhancements based on their impact on the user experience.
