I read an article about an incident at a hospital where it said: ‘ through inattentiveness by nurses …’ they were able to connect the wrong valve. Even thought there were ‘clear identifiable differences’. They made the valves ‘nurseproof’ (Imming, 2014).
I sometimes hear the term nurseproof used in the same way as foolproof, because nurses are able to break anything, push the wrong buttons, connect plugs the wrong way or even break them. Maybe the results are the same, but I think there is an important difference between nurseproof and foolproof.
So what is nurseproof? In a book by Higgs it says: “Nothing is nurse-proof, and if it can be broken, it will be.” Another explanation is in a book on integral product development (Buijs, 2005): “Medical personnel are generally careless with equipment, because the patient comes first.”. And some designers forget that the focus of the nurse is not on their product, but the patient attached to it.
Yes designer, you! I’m talking about you, watching that beautiful 3D-drawing on the screen and enjoying the geometric shapes of the design. Are you getting highly enthusiastic of your round 4-pins plug that goes in the machine? Feeling aroused by the perfect proportions of the embossed arrow on it, that points to the dot on the machine, so it’s clear for everyone how to use it? Shall I tell you why it sucks?
Because at night, when most technical personnel is gone, the battery starts protesting. And a nurse is wondering why that specific medical product isn’t charging even though it’s still plugged in. Checking the line, with a patient in bed watching, wondering what the problem is. And after searching and pulling, while her patient is getting annoyed so late at night, she finds the beautifully designed arrow and dot not being aligned. Another health care worker has rotated the plug 90 degrees. Just because it can be done. Just maybe because the lights were dim and arrows and dots are not visible then?
Interesting is also the information on the screen of this product. When it is not plugged in, it doesn’t specifically show that, until the battery is empty. When the product is plugged in and charging, it’s showing with an icon. So to know it isn’t charging, you need to see it charging? The solution is not RTFM, this is designing for nurses.
So when nurses aren’t paying attention to your product, it’s not because they don’t bother. It’s just because they care!
