BACKGROUND
"Designing systems tailored to Chinese hospital practices, addressing procedural inefficiencies"
China’s reliance on globally dominant devices like Mammotome, designed for Western markets, has resulted in procedural inefficiencies due to misalignment with local practices. This creates a critical opportunity to enhance compatibility, efficiency, and patient outcomes in breast biopsy procedures.
Identifying Workflow and Design Challenges
"Resource Management and Capacity Pressures had driven the procedural changes in preparation and sterilization, leading to inefficiencies"
On-site interviews with medical staff at six hospitals revealed that resource management and capacity pressures had driven the procedural changes in preparation and sterilization, leading to inefficiencies. Changes in management roles have also standardized similar practices across hospitals. Furthermore, designs targeting Western markets fail to align with Asian ergonomics, significantly impacting operational efficiency.
Research Methods:
Observe simulated operations and conducting interviews with product users
Research Goals:
For the team to gain a deep understanding of realistic clinical usage scenarios and user needs. Results served as a critical input for the new product development requirements
Analysis
Setup barriers
Lack of familiarity with the system often delays efficient setup
Duty nurses, who rotate every 8 hours, are primarily responsible for transporting the system and setting up the control module. However, their lack of familiarity with the system often delays efficient setup before the surgeon’s arrival, impacting overall workflow efficiency.
Highlights
The use of Sterilization Bags
Lack of proper tools makes this workaround not as efficient
Sterilization between procedures is a significant challenge, especially for lower-end models with open specimen chambers. Some hospitals attempt to shorten this process by using sterilization bags to cover the holster, but the lack of proper tools makes this workaround inefficient, often requiring two people to complete the task.
Strategies
Streamlining Breast Biopsy Procedures
Prioritizes efficiency and effectiveness
by leveraging tangible and digital solutions
to enhance the experience for surgeons, assistants, and nurses. Hence, minimizing resource waste during breast biopsy procedures, benefiting hospital operations.
Co-Design with Experts
Addressed stakeholder concerns and mitigated risks early.
Co-design sessions integrated into the risk management process addressed stakeholder concerns and mitigated risks early. This sessions also supported the development
and validation of proof-of-concepts before final implementation.
Redesigning for Asian Ergonomics
Align with Asian ergonomics and better suit local breast biopsy procedures. And also benefit to general users.
Co-Design Workshop
Design Concept Evaluations & Co-Design
Six experts from the initial interviews evaluated conceptual designs, interface layouts, and mechanical solutions for the holster. The workshop also involved refining clay models to achieve the most ergonomic design for diverse operational scenarios.
Research Methods:
Prototypes were tested through simulated operations, followed by discussions with participants
Research Goals:
Determine optimal product layouts and mechanisms while ensuring the ergonomic design of the hostler for enhanced comfort and usability.
Design
conclusion
This is a design recreation of a previous project. In this case study, I used new UX+ design methodologies based on insights from online resources to identify experience issues. I used a different design approaches to improve and refine the design concept to directly address those challenges.
