Lost in communication

Despite all the talk about how important is communication in healthcare, there are still gaps that can be easily prevented.
All the hospitals I visited  as a patient or as a companion, even to those which are top-notch in terms of quality and technology, show signs of communication gaps between nurses and doctors, especially in the outpatient setting. This may not be a big issue for some, but that what makes it hard to justify not being fixed.
When you visit a clinic for the first time,the nurse may ask for some info about you chief complaint, and your past history. You would expect that such information will be relayed some how in writing or through those sophisticated HIS applications many hospitals use nowadays, or at least, through verbal communication. Few minutes later, you step inside and meet the doctor, and he usually repeats the same questions of the nurse, not because he wants to verify something, but clearly because he doesn't know about your conversation.
Why ? why such repetition of information which wastes everyone's time? why can't nurses and doctors share information together and save the patient repeating the same story, as if he/she is treated by two different care providers ? Aren't physicians, nurses, and other providers part of  one team? What is the ROI of expensive information systems if it can't make communication smoother with less redundancies ?
Obviously, working in silos is still a big problem in healthcare, even within a close outpatient environment, and that would definitely hinder information flow.
The impression on the customer-the patient in this case-may be bigger than the problem itself. The first impression one would get is that there is not any team but several individual providers attending to you, and this would greatly impact the level of trust in the care.This may also be the first sign of many small communication gaps down the care stream that could jeopardize patient safety at any stage.
To close this gap and prevent the wasted time and efforts, one could think of many countermeasures that can be chosen according to the setting. One could be verbal communication which strengthens the bond between the care providers, or filling in  electronic forms that appear in front of the physician's screen and his job would be to go over them in details.
Let's imagine the ideal scenario, you visit a doctor for the first time, the nurse would take a brief history and your vital signs, then she would put that in your records, then you see the doctor, he would tell you that you had such and such, and ask you to elaborate more. Now that is a good first impression about a collaborative care team.
