Alan,
Roy is correct there was a ghost situation awhile back with the 10PM to midnight thing. It didn't affect me (I am immune to ghosts), but I think it is fixed now.
Brian is definitely onto it. It most likely boils down to one of three things:
1. Someone is forwarding charts to the wrong user. It can happen easily, but it wouldn't explain your situation from YOUR end. I am sure you don't screw up your forward 20% of the time.
2. Part of the crossing in mail would possibly be pulling from the scheduler. Brian and others can help better there.
3. The key is to see how many of the same name charts are in your inbox. If there are two, then possibly your nurse pulls a chart and does the subjective on the left and forwards it to you with nothing on it -- as he/she should. Then you open the chart from the patient list (something that should never happen unless you are working by yourself). You then fill out the entire chart including the physical and forward it to yourself. If you then opened the nurses' chart, it would appear as if nothing were in there.
Now, I realize this doesn't all make sense, because you would probably try both charts. For lack of a better phrase, this sounds like the charts are crossing in the mail. If you were to open a chart (from the patient list), type in it, then forward it, when you open it; it should all be there.
Hopefully, you can become confident in it so you don't have to print out a sheet of paper each time.
I just have to put a shout out for the following method, although Brian and others will kill me, althogh Adam won't. The sooner you can get to where you finish the chart AND sign it off in the room the better. Just my two cents. Good luck.
PS: There is almost always user error involved. There is probably something which would explain it. You have to remember if you are using the scheduler and you have MAs forwarding charts to you AND you are pulling some from the patient list, you have a chance and probably will have two to three different versions. After thinking about this, my suggestion (especially given my bias where I am not used to the scheduler), why not:
For one day, do not have the nurses do any charting or forwarding. ONLY pull charts from the patient list. After you are done with them, forward them to yourself. Stay away from charts on the scheduler. I am willing to bet if you do this that all charts at the end of the day end up having everything you wrote in them.
