If I understand correctly you have no records older than approx. one year? I would scan the whole thing into AC and shred the paper. I would take the time to pull Labs, Consults, EKGs, and X-rays, scan them separately and get the date right on the import action. Then the progress notes, and any miscellaneous insurance info, authorizations or whatever goes in one spot, "old Records" but be sure to label it with your name so you can easily spot your old chart from records received from another Dr.
