>1. A QR code on the bed would still be a layer of indirection and if it's patient specific, something else to print and get lost. Patients are already given bracelets with bar codes. But there are many reasons why they may not have used bracelets with their system: It may have felt too intrusive a way to greet patients. The backend system already maps patients to rooms and providers are used to thinking this way. Providers are also accustomed to confirming ID verbally with patient and always using the bracelet to be absolutely certain when dispensing meds or starting a procedure. Finally, in an emergent situation the bed can be surrounded by providers, and asking everyone to step back to scan a bracelet just to look something up in Glass would not be okay. Yes, when I thought about it a bit more, I could see advantages to having this indirection. An d if that is how the "system" is already set up, then all the better. I can imagine though that there may be cases of room transfers without a system update which may cause problems at times, but they will do anyway, not just for supporting this technology.
