Medical Equipment Library Design: Revealing Issues and Best Practice Using DiCoT
- 1. Medical Equipment Library Design: Revealing Issues and Best Practice Using DiCoT Julia Werth & Dominic Furniss
- 2. Clinical practice often evolves in response to local issues and opportunities, hence it is diverse. Can we recognise, describe and compare this diversity to reveal issues and best practice across similar clinical settings?
- 3. Content • What is DiCoT? • What is a Medical Equipment Library? • What design opportunities did we recognise?
- 4. DiCoT: Distributed Cognition for Teamwork • Where did DiCoT come from? Open Clip Art from papapishu 2007
- 6. • Distributed Cognition • Focuses on socio-technical systems • Focuses on the propagation and transformation of information • Uses information processing concepts • E.g. How a cockpit remembers is speed
- 7. • Contextual Design • Advice on doing observational studies • Focuses on developing models and representations of work practice • Models used for reflection, assessment and design
- 8. DiCoT’s Five Models • Information Flow Model • Physical Model • Artefact Model • Social Model • Evolutionary Model Open Clip Art from Geralg_G 2010
- 9. DiCoT Principles (an example) Information Flow Model’s Principles • Information movement • Information transformation • Information hubs • Information buffers • Communication bandwidth • Informal and formal communication • Behavioural trigger factors
- 12. MEL1 Physical
- 13. MEL2 Artefact
- 14. MEL Social
- 15. MEL Evolutionary
- 16. Design Opportunities and Requirements
- 17. Process • Focus (on Medical Equipment Libraries) • Data gathering * • Develop 5 models • Comparisons between contexts • Issues & Best practice • Design opportunities & Requirements *
- 18. Data Gathering • 6 visits in total (4xMEL1, 1xMEL2 & 1xMEL3) Visits lasted between 1-4hrs • 3 interviews with management at MELs • 5 interviews with experts across UK • Feedback and validation on results
- 19. Design Opportunity 1 Identification and Tracking of Equipment • Medical devices go missing – £££ • T-card system was good [Situation Awareness] • Out-of-hours is a particular problem • RFID?
- 20. Design Opportunity 2 Better Administrative Systems • MEL2 uses codes for devices e.g. D01, D04 • MEL2 and MEL3 use T-card system • MEL1 non-streamlined (notes-forms-database) • Usage reports were recognised as good practice but MEL1, 2 and 3 did not do them • Barcodes? QRcodes?
- 21. Design Opportunity 3 Solutions for Out-of-hours Working • MEL1 has a skeleton service at weekends • MEL1 has a smaller room for devices that are frequently used • ID card entry to gather ‘who’ and ‘when’ • CCTV for tracking people • Regular libraries have self checkout?
- 22. Design Opportunity 4 Better Knowledge Sharing and Support Between Practitioners • Currently some meetings and word-of-mouth • EBME discussion forum • NAMDET • Developed online community support tools? • Our small scale study reveals best practice
- 23. Design Opportunity 5 Usage of Physical Space and Dedicated Areas • Space is often limited (MEL1 is bigger) • Need separation between dirty and clean areas • Clear barriers? Disinfectant sprayed? • Equipment that knows it is dirty? Violation alerts?
- 24. Content • What is DiCoT? • What is a Medical Equipment Library? • What design opportunities did we recognise?

Editor's Notes
- Say a bit about Me, Julia and CHI+MED.
- This provides the broader backdrop to this paper and a wider research agenda that we’d like to push forward.So we need a METHOD to be able to do this recognising, describing and comparing. [DiCoT]And we need an interesting case study to act as a test case [Medical Equipment Libraries]
- DiCot is interested in understanding socio-technical systems as systems full of information processing.If we imagine DiCoT as a baby…
- … then it was born out of a loving relationship of its parents: “Cognition in the Wild” and “Contextual Design”But what did DiCoT inherit from each side?The latter is big on the theory.The former on methodology and practical guidance of doing field studies of socio-technical systems.
- Stronger on theory
- Stronger on method
- All of these models help to paint a picture of the socio-technical system.The models are overlapping, interdependent and complementary.
- This is an example of DiCoT principles for the information flow model. These help the analyst colour the picture, and guide their observations.
- What interested us about Medical Equipment Libraries?Important role to play in medical device managementNew – some hospitals use them and some don’tNewish – potential for supportWe did not know how they worked
- This is a high level information flow diagram.The information flow will also include the different tasks that comprise the system.
- This is a physical model of MEL1.C = cleanD = dirtyR = repairO = office/admin
- This is a T-card system used by MEL2 and MEL3.It provides a way of tracking devices, and supports situation awareness.
- This is a social model which looks at how roles and goals are distributed.I won’t explain this but have included it for completeness – there are more details of this in Julia’s original MSc thesis.
- The first MEL were established about 15 years ago.As the evolutionary model shows that have been various developments and documents that have impacted on the way that things are today.Now there is quite clear guidance to set up a hospital function to centrally manage and maintain a lot of medical equipment.However, some hospitals do this, others don’t and some are thinking doing it.
- This is the rough process we took through the project.We have covered the focus, and referred to the 5 models above.*for the sake of brevity I will jump to these two
- D01 – specific model of feeding pumpD04 – is a suction pump
- This is what we’ve covered.
- This is a nice message Julia received from someone with a lot of experience in the NHS.Her full thesis can be accessed fro the SIGHIT Thesis repository.
