Workshop 11 (Afternoon 2:00 - 5:00) Title: INCORPORATING THE NEEDS OF USERS INTO POINT-OF-CARE DIAGNOSTICS Presenters: Jacqueline Linnes, Purdue University, USA Elizabeth Johansen, Spark Health Design, USA Ashok A. Kumar, Jana Care, USA Workshop Description: Human Centered Design provides set of methods to engage with users before and during the development of a diagnostic device in order to improve clinical diagnoses, regulatory approval, and commercialization outcomes. No matter how accurate a point-of-care diagnostic may be, if users are frustrated by the device (e.g. the results of a colorimetric test are too subtle to interpret) or the device is difficult to fit into the clinical workflow (e.g., the time for the test is significantly longer than the average provider visit), it will have trouble achieving widespread use and competing devices with poorer technical performance but better user-design may be adopted instead. The goal of this workshop is to provide both an overview and practical experience using the HCD framework so that participants can design translational devices that ultimately meet the needs of the patients and caregivers who will actually use these diagnostic technologies. Outline: Workshop attendees will create a mock point-of-care diagnostic device prototype, and develop a product hypothesis by defining potential users, their needs, and the critical assumptions that they have made about the context of device operation. They will then prepare for, and take part in role playing to engage with each other as potential users of the device and finally synthesize this information into a new hypothesize with changes to the device design and use. An example challenge and device include: Assume that you are working in a company that assists small shareholder farmers (1 acre or less for their home and farm) to enable them to gain market share when selling their fruits locally, and potentially internationally. If they can prove that their fruits are higher quality than competitors, people will purchase from them instead of others. Your team has designed a colorimetric paper-fluidic pH detection bandage to determine acidity of fruit skins because the surface of fruits changes pH when they are damaged by insects/environment. Working in a group of four, you will design a simple fluidic delivery system, write out interview questions for a farmer/field hand, and find out how this potential user would actually interact with the device. |
