We did another trial in the hospital yesterday, using just 1/2 of the MICU. Set-up in the hospital took approximately an hour and 15 minutes.
The biggest time consumer was the pucks. Using the velcro took a long time, but to prepare for that for the full test, we can set out the pucks the day before, or do half of the velcroing in the lab. We only put the pucks on the brackets outside the patient rooms or on the desks, we skipped any bottles inside patient rooms.
Putting the motes in the patient rooms went smoothly. They were plugged in to the panels, so we didn’t have to worry about battery life. Pyramids were placed at the nurse’s station and in the doctor’s work room. They were plugged in to the computers, and we had no problem with that.
We waited until the night nurses left to hand out pagers to the day nursing staff. Most of the doctors came to round at about 8:30, so we handed out pagers as they came in.
All in all, the parts did well in the hospital. We had some glitches with the pucks, but everything stayed in place, and nobody messed with anything. We left one bed mote in a patient room, and three pagers are missing.
The data didn’t look the way we expected it to look. The pagers heard from the pyramids, but not from the bed motes. There are very few bed mote records in the data sets, though we saw nurses walking around. We see times where a puck was hit, but then the nurse disappears until the puck is pressed again. Possible software bug?
