However, I am focused on the precautions side of the room identifications. In many hospitals there are still signage and documents that notify nurses and doctors of precautions to take when entering a patient's room
Ok, just saw this part. We too have the contact/droplet/airborne signs on the doors. I don't need reminders for MY assigned pts. However we enter other nurses' pts when they are tied up or on break -- you can bet I look at them, because I don't know their history. If they're not assigned to me, I haven't taken report. Plus, the signs are for the benefit of visitors, for non-clinical staff (e.g. dietary or housekeeping staff), for consulting physicians who are typically not located on our unit.
The signs work fine. I don't see the need to improve on them because they are not a problem. They convey the necessary information to EVERYONE entering the room -- not simply those who have been in the chart to see the "Contact precautions: MDRO"... or those who know, say, a color code used by a hospital in lieu of the actual information. The directions, such as "gown and gloves, wash hands with soap and water" for C. diff, also spare the nurses from having to intercept Every. Single. Person approaching the room to TELL them what they need to don.
I honestly don't see a problem to be solved.
