Research shows these “big three” categories account for about 75 percent of all serious harms from diagnostic errors.
Patients can help prevent a misdiagnosis
Can diagnostic errors be prevented? That’s a goal that many experts are working toward, and believe it or not, you, as a patient can help.
1. Prepare for appointments. Before your appointment, take some time to think through your symptoms and concerns. Write them down and bring these notes with you to the doctor. “This is really about boiling down your symptoms and the timeline of your symptoms into a very simple format [that’s easy for the clinician to digest],” Newman-Toker says. The Society to Improve Diagnosis in Medicine, a physician-led patient safety organization, has a worksheet for patients to help them outline and organize their medical history, symptoms and concerns.
“If the doctor gets kind of a nice, one-page executive summary or whatever you want to call it, then they’re going to spend more time thinking about the problem and less time gathering the information,” Newman-Toker says.
2. Ask questions. It’s important to ask probing questions about the diagnosis you’re given and why other conditions were ruled out. For example, if bad headaches bring you in and your doctor diagnoses you with cluster headaches, ask why that’s the case and why it’s not a migraine.
“What you’re looking for is a reasonable set of answers to those questions,” Newman-Toker says. “You’re looking for a thoughtful explanation, not defensiveness.”
3. Follow-up. Finally, keep track of your progress after a treatment plan is prescribed, and stay in touch with your doctor if things don’t get better. If symptoms persist, it’s common for a patient to assume that the treatment is to blame, not the diagnosis, Newman-Toker says. And if the patient calls the doctor’s office and asks for a medication change or a higher dose, “the doctor won’t rethink the case.” To get a second look, call the doctor and say, “I’m not getting better. Are we sure that I’ve got the right diagnosis?”
“I think people don’t realize how important patients’ voices are in a diagnostic process,” adds Singh, who is also a co-author on the latest JAMA study. “Because it really helps us not only make the original diagnosis … but also to question the diagnosis later if things don’t get better.”
A few other tips: Keep an accurate list of your medications, and bring this with you to all of your appointments. Also, keep your own records of test results, referrals and hospital admissions.
When to get a second opinion
If things don’t get better, or if you are suspicious of a diagnosis and want to confirm it, consider getting a second opinion from another physician, perhaps a specialist. Your doctor may even recommend it.
A study from researchers at Mayo Clinic found that around 20 percent of people who sought a second opinion got a different diagnosis from the first; about 66 percent of patients received a refined or redefined diagnosis when seeking a second opinion.
When asking for a second opinion, be as “direct and unemotional as possible,” the experts at Columbia Surgery in New York City, recommend. Some patients find this part difficult, especially if they have an established relationship with their doctor, Singh acknowledges. “But there are ways that you can express concerns assertively to the clinician, so that they understand what your concerns are,” he says. “And that could be, ‘This is a life-changing diagnosis. I’d like to see a second opinion to make sure we’re on the right track, and I’ll come back to you once I’m able to confirm that.’ ”
When the appointment for your second opinion rolls around, be sure to bring all the details from your previous diagnosis, including test results and recommended treatment plans.
