One in five patients who read their own doctor’s notes online say they found a mistake, and nearly half called it serious.
Story Snapshot
- A JAMA Network Open study of 136,815 patients across three U.S. health systems found 21.1% of note-readers spotted a perceived error.
- Of those, 42.3% described the mistake as somewhat or very serious, often involving diagnoses, medications, or test results.
- Federal rules now require most health providers to share visit notes electronically with patients right away.
- Smaller pilot programs let patients flag errors directly, and clinicians confirmed enough reports to change records or care plans.
The Numbers Behind the One-in-Five Finding
Researchers invited 136,815 patients across three health systems to answer questions about their visit notes. Nearly 30,000 responded, and 22,889 of them had actually read a note in the past year. Among those readers, 4,830 people, or 21.1%, said they spotted at least one mistake. That is not a fringe complaint. It is roughly one in five people looking at their own paperwork.
What Counts as a Serious Mistake
Finding a typo is one thing. Finding the wrong diagnosis is another. Of the patients who flagged an error, 2,043 called it somewhat or very serious. The most alarming reports involved incorrect diagnoses, wrong medical history, medication errors, physical exam mistakes, mixed-up test results, and even notes written for the wrong patient or the wrong side of the body. Those are not clerical slips. Those are the kind of errors that can steer a treatment plan off course.
A separate pilot study backs up the pattern. Among 8,648 participants who read a note, 1,434, or 17%, perceived a mistake. Of those, 44% called it serious, and more than half of that group, 342 people, contacted their provider directly to sort it out. Patients are not just noticing problems. Many are acting on what they find.
How the Open Notes Movement Changed the Rules
These findings did not happen in a vacuum. A federal Information Blocking rule took effect on April 5, 2021, requiring most health providers to give patients electronic access to their records, including visit notes, as soon as they are ready. The policy grew out of the OpenNotes movement, which pushed the idea that patients read their own charts more carefully than anyone gives them credit for.
Before that rule, sharing notes was mostly voluntary, and many systems held back. Once access became standard, the volume of patient eyes on medical documentation jumped, and so did the number of reported discrepancies. Visibility did not create new mistakes. It simply gave patients a chance to catch ones that were already there, sitting quietly in a file nobody outside the clinic ever opened.
Why Patient Feedback Tools Matter
Some health systems built formal ways for patients to report what they found. In one pilot, 6,225 patients were invited to submit note feedback, and 2,736, or 44%, actually read their notes. About one in twelve of those readers used the feedback tool, filing 260 reports. Nearly a quarter of those reports were flagged as documenting a genuine safety concern, not just confusion over wording.
Another study found that 331 patients, about 7% of those surveyed, went further and called their doctor’s office directly about something in their note. Of those calls, 29% turned out to involve a real perceived error, and 85% of patients were satisfied once the office resolved it. That is a workable feedback loop, not a bureaucratic dead end.
What This Means for Patients Reading Their Own Charts
The consistent thread across every one of these studies is simple. When patients get a real look at what their doctor wrote down, a meaningful share of them find something worth flagging. Most of those reports are minor. A good chunk are not. For anyone with online access to their chart, checking the notes after an appointment is turning into basic self-defense, not paranoia.
