Extraordinary design considerations e bacon 2011 08-05

  1. 1. ExtraordinaryDesign Considerations for Medical DevicesElizabeth Bacon @ebaconAugust 5, 2011 #d3 #edc
  2. 2. My talk today I presume you are an audience of seasoned design practitioners Introduction Regulatory Landscape Key Design Tools Tips & Encouragement Extraordinary Design Considerations for Medical Devices ■ D3 2011
  3. 3. Thesis Typical design tools apply, but they have to play out in a unique regulatory framework Rather text-heavy on purpose to be a helpful artifact for people not here today Extraordinary Design Considerations for Medical Devices ■ D3 2011
  4. 4. Introduction Interaction Designer’s perspective Principal Consultant 1999 - 2002 Cooper Sr. Human Factors Design Engineer 2002 - 2007 St. Jude MedicalLiz Bacon Chief Design Officer 2007 - 2011 Devise Director Emeritus IxDA Extraordinary Design Considerations for Medical Devices ■ D3 2011
  5. 5. Regulatory landscape Regulatory controls depend on class of device ๏ Class 1 ๏ Class 2 ๏ Class 3 Extraordinary Design Considerations for Medical Devices ■ D3 2011
  6. 6. Agencies FDA (U.S.) / TÜV (Europe) ๏ Enlightened, user-centered folks ๏ Based on HFE approaches Extraordinary Design Considerations for Medical Devices ■ D3 2011
  7. 7. HFE origins Extraordinary Design Considerations for Medical Devices ■ D3 2011
  8. 8. Burden is on the process Formalizing product design & development process with “design controls” is critical for regulatory compliance ๏ Regulatory bodies produce guidance documents via ANSI/AAMI, and IEC ๏ Companies have SOPs: standard operating procedures ๏ Departments have DOPs: departmental operating procedures Extraordinary Design Considerations for Medical Devices ■ D3 2011
  9. 9. Key standards HE75: 2009 IEC 60601-1-6, IEC 62366-2007 60601-1-8 Extraordinary Design Considerations for Medical Devices ■ D3 2011
  10. 10. Process diagrams 60601-1-6 Extraordinary Design Considerations for Medical Devices ■ D3 2011
  11. 11. 62366 HE75 Extraordinary Design Considerations for Medical Devices ■ D3 2011
  12. 12. 62366 HE75 Extraordinary Design Considerations for Medical Devices ■ D3 2011
  13. 13. HE75 Extraordinary Design Considerations for Medical Devices ■ D3 2011
  14. 14. Design “inputs” Design inputs are recorded in a “design history file” or “usability engineering file” COMMUNICATION IS KEY Extraordinary Design Considerations for Medical Devices ■ D3 2011
  15. 15. Design “outputs” DOCUMENTATION IS KING Extraordinary Design Considerations for Medical Devices ■ D3 2011
  16. 16. Risk management Analyzing & mitigating systemic risk ISO 14971:2007 Extraordinary Design Considerations for Medical Devices ■ D3 2011
  17. 17. Product requirements Product requirements must be maintained — and they must be testable & traceable The system shall... Extraordinary Design Considerations for Medical Devices ■ D3 2011
  18. 18. V & V phase Verification: that product behavior matches requirements Validation: that requirements meet needs of user Extraordinary Design Considerations for Medical Devices ■ D3 2011
  19. 19. Usability testing Formative studies Summative studies Extraordinary Design Considerations for Medical Devices ■ D3 2011
  20. 20. Collaboration rules Cross-disciplinary collaboration ๏ colleagues are highly technical ๏ too much work for design to handle alone Extraordinary Design Considerations for Medical Devices ■ D3 2011
  21. 21. Key design tools Typical UX methods apply ๏ research in context ๏ conceptual design approaches ๏ detailed design iteration ๏ usability testing Extraordinary Design Considerations for Medical Devices ■ D3 2011
  22. 22. Research in context ๏ Call it “contextual inquiry” ๏ Learn context of use pressures ๏ Identify hazards & systemic riskFollow-up room at Lehigh Valley Cardiology Associates EP Clinic,Bethlehem, PA Extraordinary Design Considerations for Medical Devices ■ D3 2011
  23. 23. User models ๏ Personas work well ๏ So very important to frame that these users are not ourselves ๏ Patients comprise the world Dr. Helena Reardon Interventional Cardiologist Extraordinary Design Considerations for Medical Devices ■ D3 2011
  24. 24. Conceptual design Scenario-based design: ๏ helps us define ideal experiences ๏ helps articulate UX requirements ๏ informs verification & validation activities ๏ even influences user documentation & marketing communications Extraordinary Design Considerations for Medical Devices ■ D3 2011
  25. 25. Detailed design Iterative, naturally ๏ Interactive prototypes for usability testing and communication with development Warning: a prototype speaks a thousand sentences, but can be hard to maintain Extraordinary Design Considerations for Medical Devices ■ D3 2011
  26. 26. Usability testing Classic, moderated, one-on-one usability testing ๏ Small sample sizes are OK per HE75 ๏ Define clear usability objectives up front in the project Extraordinary Design Considerations for Medical Devices ■ D3 2011
  27. 27. Tips & encouragement Consider user research to be an investment ๏ long shelf life for personas ๏ power of roles in medical domain ๏ nobody can own this as well as IxD Extraordinary Design Considerations for Medical Devices ■ D3 2011
  28. 28. Patterns Power of design patterns ๏ Leverage the institutionalization of protocols in clinical contexts Extraordinary Design Considerations for Medical Devices ■ D3 2011
  29. 29. Style guides Power of style guides ๏ Must be testable & low- maintenance ๏ Allows design outputs to be in low-fidelity format Extraordinary Design Considerations for Medical Devices ■ D3 2011
  30. 30. Beyond hazard mitigation Hazards can be avoided with great design Follow principles like: ๏ Make errors impossible ๏ Don’t expect users to be experts Extraordinary Design Considerations for Medical Devices ■ D3 2011
  31. 31. Stages & phases Design controls necessitate phases ๏ Ideation, Modeling, Testing process stages ๏ Conception, Framework, Detailed Design project phases Extraordinary Design Considerations for Medical Devices ■ D3 2011
  32. 32. Systems & QA best friends ๏ Make nice with Systems & QA team members ๏ Train QA folks in usability testing methods for summative usability testing Extraordinary Design Considerations for Medical Devices ■ D3 2011
  33. 33. Closing exhortations ๏ Consulting to medical device firms is going to be challenging ๏ Few design agencies are equipped with regulatory know-how ๏ Documentation is crucially important ๏ Plan for lengthy engagements with long tails Extraordinary Design Considerations for Medical Devices ■ D3 2011
  34. 34. Review draft guidances Organizations like HFES Contains Nonbinding Recommendations Draft - Not for Implementation Draft Guidance for Industry and provide access to draft Food and Drug Administration Staff guidance documents to get Applying Human Factors and Usability Engineering to Optimize member review & comment— Medical Device Design it’s needed!
