Health Tech Presentation

  1. 1. HEALTH DASHBOARD Dale Chesney Andrea DwyerProject Sponsor: Rebecca GulottaMelanie TurieoCambridge Leslie JohnstonConsultants Emily MaretskyFinal PresentationApril 29, 2010 ENP 120 Tufts University
  2. 2. Introduction Requirements Gathering Design Concepts Prototyping Usability Testing Guidelines for Future WorkIntroduction
  3. 3. What is a Health Dashboard? Enables tracking and monitoring of health information for elderly patients. Allows professional caregivers to remotely monitor a patient’s baseline health condition. Allows lay caregivers to understand the patient’s day-to-day health concerns and receive alerts about potentially dangerous medical situations. Gives elderly patients a better understanding of their own health and wellness.
  4. 4. Goals Create a health monitoring product that is attractive to elderly patients. Design a system that is useful for professional and lay care providers. Manage health information collected from external sensors in a way that is easier and more efficient than existing methods. Allow for 2-way communication between this system and electronic medical records systems.

  7. 7. User Group: Patients This group is comprised of older adults who are receiving medical care. Important Issues:  Individualhealth concerns  Health monitoring needs  Privacy and security of information  Access to health resources
  8. 8. User Group: InformalCaregivers This group is comprised of the family and friends of people who are receiving medical care. Important Issues:  Access to patient information  Level of medical knowledge  Relationship to patient
  9. 9. User Group: Formal Caregivers This group is comprised of the health care professionals who provide medical care to the patients. This group includes doctors and nurses. Important Issues:  Informationsharing between formal caregivers  Remote monitoring  Adding and removing information from the system
  10. 10. Focus Groups Talked with ten Brookhaven residents Talked with Nurse Practitioner Key Takeaways:  Resident and caregiver health concerns  Current medical information tracking  Comfort with technology  Relationships with caregivers/patients  Device expectations and implementation methods  Security and privacy issues
  11. 11. Requirements GatheringSummary Users  Use of electronic devices in public considered “rude”  Accommodation of different stages of life Environment  Privacy of information in the home  Flexibility to complement users’ routines Functional  Reference for health concerns but not diagnostic  Interaction with wired and wireless sensors Performance  Short term and long term storage capacity  Locator for misplaced handhelds
  12. 12. Design Concepts
  13. 13. Design Concept: Kiosk
  14. 14. Design Concept: Dock withHandheld
  15. 15. Design Concept: Dial
  16. 16. Design Concept: Folio
  17. 17. Narrowing Design Ideas Considered feedback from focus groups and initial design presentation. Rated and discussed how well each concept met the defined requirements:  User needs  Functional requirements  Performance requirements  Environment requirements Selected combination of most appropriate concepts.

  27. 27. Usability Testing
  28. 28. Usability Test Design Assess preliminary design and gather information for further improvements. Main Goals:  Ensure that users can easily navigate through the interface  Ensure that users are satisfied with the dashboard’s features  Identify potential feature changes and additions  Understand how users interact with the device and dial/dock  Is information presented in an easy to interpret manner?  Evaluate usefulness and acceptability of proposed health measurements and data.
  29. 29. Usability Testing Usability tests conducted with five sample users from Brookhaven consisted of:  Pre-test questionnaires  Two example use scenarios each for dial and dock  Follow-up survey about experiences with sample tasks, overall experience, and opinions
  30. 30. Usability Testing  Looked for  Objective results regarding the users performance on accomplishing tasks  Subjective feedback concerning how user felt about the system
  31. 31. Usability Test Results Key Takeaways:  Menu labels were ambiguous but menu mode clearly communicated  Interest in more information for medications and recording options for exercise  Some options seemed directly “clickable” when they were not  Interest in a physical arrow on the rotary dial  Some users found the exercise log feature confusing  Interest in a power button for the dock  Tabs in Weight confused for action buttons  Users emphasized customization for Current Health feature
  32. 32. Redesign Recommendations  Re-label design menus  Add screens for individual medication information  Make more options “clickable”  Add a physical arrow on the rotary dial  Reorganize the exercise log feature  Include a power button for the dock  Change the tabs in Weight to a visual progression
  33. 33. Guidelines for Future Work
  34. 34. Guidelines for Future Work on Health Dashboard Concept1. Allow for customization • Both caregivers and residents stressed the importance of being able to customize the content available in the system and its interface to reflect individual physical limitations and health concerns.2. Avoid ambiguity • The residents were uncomfortable using interface elements that did not have a clear outcome. Menu items and icons should convey information about what lies beneath.3. Adapt to existing lifestyles • The system should reflect the habits and routines that play a pivotal role in the care of adults with health issues or who are living in senior communities.4. Track appropriate metrics • Health conditions can vary greatly from person to person and it is important to provide both patients and caregivers with the appropriate information and tools to collect that information.5. Encourage continued use • In order for the system to have value to both caregivers and patients, it is important that
