Good to hear that you perceive a real time savings for the patient. Interesting, because usually the discussion is whether it makes doctors more productive (generally, they say documenting notes electronically is more time consuming), but everyone says the end goal should be a payoff for the patient. If your doctors having EHR gets you in and out of the office quicker, that's a payoff that shouldn't be discounted.
Presumably, you would see even more benefit with good health information exchange between providers and between hospitals and practices. If everyone you are seeing is on the same EHR system, great, but often that's not true.
