It is complicated. I was working in a state psychiatric ward during university, and the ward psychiatrist had noted in the patient's chart that after meeting the patient's mother, he suspected a genetic etiology of the patient's condition. In other words, the patient's mother was also crazy. The patient's mother, having received legal access to the chart, read that, and was now suing the state. The earlier comments in the thread about the target audience was spot on. Radical record transparency may perhaps not always benefit health professionals, unless of course, some things are just not recorded - and that may not benefit the patient.
