I try to deal with one patient at a time, but frequently the first patient forgets something after she is done, then I have to close the second patients chart, go back to the first patients chart, address the issue, then close the first patients chart, then open the second patients chart again.
I agree with your basic point that 8 seconds is too long when we need to open and close charts so often. Not to get off track on the "open two charts at once" debate, but remember that while one spouse's chart is open, you can e-prescribe, open and use the Letter Writer, or write orders on the other one.
