Scenario 2: Equipment
Description
Our prototype demonstrates access to patient equipment information. Our approach supports entry of the equipment details along with the addition of notes and attachments and can be applied to any type of medical equipment, implant or device.
Advantages over Current PHR/Patient Portals
We have discovered a few PHR/patient portal systems that support the ability to store equipment information, but most seem focused specifically on implants and/or their purpose is not clear.
Usability Test Scenario Description: Scenario 2a
Background:
Imagine that you have a collection of home health equipment including an electric bed, patient lift, shower chair and a very expensive electric wheelchair that is critical to your mobility and independence. Your wheelchair needs to be serviced and repaired. You know from experience that you need specific information about your wheelchair when contacting the repair facility.
Goal:
Use the system to do the following:
- Locate the model name, model number and all serial numbers for your chair.
- Use the system to make a note of the service request.
Usability Test Scenario Description: Scenario 2b
Background:
Imagine that you had a hip replacement about seven years ago. You read an article about a recall of artificial hips and you are very concerned. The article includes the model numbers and lot numbers of the recalled artificial hip implants. You called the hospital where you had the procedure and they gave you some general information.
Goal:
Use the system to do the following:
- Locate the model name, model number and lot number for your hip implant.
- Use the system to make a note of your call to the hospital.

Participant Comments:
- Could I use this to track things like catheters?
- I would use this to track lots of things including medical supplies.
- You can never have too much information on your equipment.
- I have files and spreadsheets with all of this information.
- The word “equipment” didn't mean anything to me.
- I think I would take the time to enter all my equipment here.
- This would be so helpful to me.
- I don't have any medical equipment, but this would help someone who does.
- Could be better in accessibility. Screen reader navigation was confusing.
- This is not addressing people who are deaf and are not literate in English.
- This needs to be translated to sign language.
Discussion and Recommendations:
Participant #6 self-identified as having a cognitive disability and seemed to have difficulty in understanding and recalling scenario objectives. Participant #7 did not self-identify as having a cognitive impairment, but also had difficulty in understanding and recalling scenario objectives. As a result both of these participants could not complete this task (and almost all others) without assistance.
