Doctors often say that one of the key reasons they order medical tests or treatments they know are unnecessary or ineffective is because patients insist that they do so.
Well, those doctors may be misreading their patients, at least when it comes to many older patients. According to a new national poll, one in four Americans aged 50 and older (the age group that uses the most healthcare services) say their doctors frequently order tests or prescribe drugs that the patients don’t think they really need.
One in six of those patients said it happened within the past year.
“Conventional wisdom suggests that patients drive overuse of low-value health care services because of their health care preferences,” the report says. “Results of this poll suggest this may not be the case.”
The findings also underscore the need for “patients and providers … to work together more to prevent overuse of health care services that provide the least value to patients,” said the study’s lead author, Dr. Jeffrey Kullgren, a research scientist at the University of Michigan’s Institute for Healthcare Policy and Innovation, in a released statement.
Indeed, the poll makes clear that patients and doctors are not doing a good job of communicating with each other.
Unnecessary medical care is one of the most serious issues facing the U.S. healthcare system. Not only can it cause harm to individual patients, it’s also a major financial burden. As Dr. Atul Gawande reported in a 2015 article for the New Yorker, unnecessary medical care accounts for about a third of healthcare spending in the U.S. — or $750 billion each year.
That’s “more than our nation’s entire budget for K-12 education,” Gawande pointed out.
Some surprising findings
For their report, Kullgren and his colleagues surveyed a nationally representative sample of 2,007 Americans aged 50 to 80. The researchers focused on patients because most past surveys on the topic of unnecessary medical care have tended to seek the opinions only of doctors and other healthcare providers.
The current survey revealed some unexpected responses, said Kullgren.
“We were surprised to find that only 14 percent agreed that more medical care is usually better,” he explained in a video that accompanied the release of the report.
The survey also revealed that many older adults (54 percent of those polled) believe that doctors too often recommend “low-value” health services — ones that, in Kullgren’s words, “aren’t going to improve most patients’ health outcomes and could lead to unnecessary harms and costs.”
A quarter of the surveyed patients — 25 percent — acknowledged that their own doctor made such recommendations. And 17 percent said their doctor had done so within the past year. The most common types of services that the patients thought had been unnecessarily recommended to them were tests (such as an x-ray or a blood test) and medications.
“Yet about half of those patients ended up getting the service anyways, which suggested to us that patients have a lot of trust in their healthcare provider if they’re often willing to go ahead and get a service even if they feel like they don’t really need it,” said Kullgren.
On the other hand
The survey also found that sometimes it was the patient, not the provider, who insisted on receiving a low-value medical service. This situation, however, was not as common. Only about 1 in 10 of the surveyed patients (9 percent) said they had disagreed with a doctor who had told them within the past year that they didn’t need a particular medication, test or procedure.
When this happened, most of the patients (79 percent) received an explanation from their doctor about why the service wasn’t necessary, but only 60 percent said they had completely understood the explanation.
“Patients don’t always expect more health care,” said Kullgren. “What they do expect is a conversation with their provider about what kind of health care is going to help them most to improve their health and that is unlikely to lead to unnecessary harms and costs.”
“There certainly are things on the provider side of the equation or on the patient side of the equation that can lead us down the path of patients getting too many low-value services,” he added. “So it’s important to identify what some of those drivers might be and then develop solutions to those problems.”
Five important questions
1. Do I really need this test or procedure?
2. What are the risks and side effects?
3. Are there simpler, safer options?
4. What happens if I don’t do anything?
5. How much does it cost, and will my insurance pay for it?
