HUMA: A Patient-Facing Digital App for At-Home Infusion Care

Project Overview

As UX lead, my objective was to design a patient-facing digital application to support at-home infusion care for patients with immunodeficiency. The project involved reviewing the design from other designers and working on complex features such as voice integration, infusion log, and inventory management. My main responsibilities were to prepare interview and usability test protocols, run the usability interviews, analyze the data, prioritize it, and work with product designers to reiterate on the initial design.

Research Analysis

  • Collected 2 years of research from different companies like TribeOne, IDEO, MadPow, and Langland. The research consists of low-fi screens that were tested and validated and came with recommendations.
  • Structured the research and prepared Personas, Summary of research and key insights, Customer Journey Map, Assumptions, Validations, Recommendations, Research Gap, Product strategy, and Low fi screens/images feedback (not clickable).
  • Defined the problem, problem statement, goal statement, and value proposition.

  • Prototyping

  • Prepared the first prototype with design guidelines and system from HUMA.
  • Conducted feedback sessions with healthcare professionals from different countries and prepared qualitative analysis based on the insights.
  • Established feedback analysis principle and set the main objectives for the study.
  • Set outcome measures/endpoint such as completion rate of each prompt, time taken to complete each prompt, number of errors or difficulties encountered, satisfaction level with each module, proportion of participants who would recommend the app to others, System Usability Scale (SUS) assessment and Qualitative data.
  • Testing and feedback analysis

  • Designed the first testing version of a hi-fi prototype to test with patients and tested it with the 20 patients.
  • Conducted interviews and analyzed the feedback of the patients for the main features of the app.
  • Interviewed each patient for 1 hour and 30 minutes to get feedback on the main features of the app.
  • Created a table to record observations, evidence, recommendations, type, module, rating, design change, priority, rationale, raise it as a task, and opportunity.
  • Held feedback review discussions with designers to prioritize design changes based on impact and effort.
  • Created tasks for designers based on their module specialization.

  • Results & Summary

    The following results were achieved:

  • Released the application on app store and play store.
  • Increased patients' ability to successfully infuse at home.
  • Increased patient and caregiver confidence and competence with treatment management.
  • Reduced/minimized treatment attrition.
  • Improved patients' quality of life/reduced burden.
  • Ensured desirability for health care providers.

  • These results were achieved through the design and validation of the My IG App using the Huma platform, which includes recommended features based on extensive research and testing with clinicians, nurses, and PID patients. The app went through seven iterations and was continually reviewed by internal teams at Huma, including clinical, regulatory, and technical experts. The development of the app was based on a solid foundation of rationale provided by Takeda's wealth of research and partnerships with external partners over two years.

    The design process included stakeholder feedback, user testing, and open feedback sessions with Takeda and external healthcare professionals, resulting in a balanced set of features that are valuable to both clinicians and patients. The app includes low-risk-of-change modules such as onboarding, profiles, caregivers, journal, and medication, as well as other features that were frozen based on research to date to hit regulatory deadlines.

    Overall, the My IG App has achieved significant results in improving the management and quality of life of PID patients and their caregivers, reducing treatment attrition, and ensuring desirability for healthcare providers.
