Today medical records are developed for a single encounter (an outpatient visit or hospital stay). The medical records for an encounter are signed off at the end of the encounter and thereafter cannot be changed. An addendum medical record could be added later to correct misinformation in the encounter medical records, but this is seldom done. This process enables medical documents to be legal recordings of what happened during each encounter. But often, proper diagnosis can only be done after multiple encounters, so when a diagnosis is recorded it is often prematurely done. Treatments may thus be tailored for the wrong diagnosis. Additionally, sometimes both diagnoses and procedures are reported for financial rather than clinical reasons, sometimes even upping the recording to get maximum payment from an insurance company or the government rather than reflecting the true diagnosis or treatment.

Combining new information from the patient, the physician could develop a thorough and complete disease history if the physician had all of a patient’s medical records and thoroughly read them all, but this is seldom feasible as medical records are hard to read and most often voluminous and medical records could exist in other medical organizations that are not available to the physician. Therefore, the disease history most often comes from the patient
