Great idea! There are institutions that do not participate in the cloud-based sharing and that would suggest that one needs to use a more direct approach at records transfer.
Your idea of a one page "resume" if you will, facilitates sharing with the providers. Keep in mind that they are bombarded with information from all sides and directions. Actively participating in your care is important.

The Electronic Health Record and Patient Portal are constantly evolving (maybe too fast) but that would be what you will see improve over time.
Best!
