You just reminded me of something. Many doctors I've spoken to don't want to use a mobile device to look up information while in the presence of a patient. It's not good bedside manner and can hurt the doctor's credibility as a medical expert (a patient may think, "Gosh, I could have downloaded that app and looked up that info myself!"). There may be a few exceptions, of course, but that seems to be the more common use case.
What you say may be true for some, but I don't mind looking stuff up in the room with a patient. Most of us try to do what's in the patient's best interests, which definitely includes in my case trying to refresh my highly fallible memory.
However (and I'm waxing philosophical here) people don't come in to hear information from their docs as much as they come in to be heard by another human.
Good docs ain't in that room with you to check off whether you had your oil changed and tires rotated, which tasks do seem like something a pad or laptop can be helpful in noting (paper does it just as well, however, and doesn't end up on the web).
Data capture just isn't the big problem in all this. A major problem is developing novel, innovative and SECURE ways to track and make USE of that data for the benefit of patients.
> innovative and secure ways to track and make use of
This brings up the very real issue that this is not just a fancy secure email app like hushmail where the data is stored and transported encrypted: here the data will live on the server decrypted at least transiently to build those novel ways to "track and make use of".
Having a doctor that reads and post here on HN is like gold for anybody developing medical software. You and the folks behind DrChrono really should touch base.
