RESEARCH says it takes 20-25 minutes to get back into the groove after an interruption. For a 45 minute class that means just one interruption can ruin a day. I’ve talked about interruptions before, including how to cope with your phone, so I’m not going to rehash them here.  It’s interesting that the interruptions didn’t increase the errors while other research with nurses did.
