Patients fewer symptoms after these words from doctors

A few encouraging words about recovery time from a health care provider after an allergic reaction significantly reduces symptoms, according to a new study.

“For many conditions, the simple act of being reassured by a medical professional can aid in the healing process, and we needn’t always rely on medication and procedures to make us feel better,” says Alia Crum, an assistant professor of psychology at Stanford University’s School of Humanities and Sciences whose research explores how patient mindsets can affect health outcomes and healing.

“My hope is that findings like this one inspire additional research on the physiological mechanisms of assurance as well as promote training and compensation for physicians to more effectively leverage psychological forces in their practice,” Crum says.

TESTING PHYSICIAN ASSURANCE

Lead author Kari Leibowitz, a graduate student, says the findings on doctor reassurance are in line with what people had known about the placebo effect.

“Research on the placebo effect has long shown the importance and power of a physician’s words: When a physician gives people an inert treatment, such as a sugar pill, and tells them it will help them feel better, that pill is often effective,” she says.

The question, Leibowitz says, is whether a doctor’s reassurance is enough.

“Our experiences talking to both patients and physicians suggest that we know that physician assurance, by itself, is powerful and can make people feel better, but there is surprisingly little empirical work to back that up,” she says.

To test the effects of a physician’s words on patient symptoms, the researchers set up a simple experiment with 76 study participants.

They began their experiment by inducing a harmless, allergic reaction in study participants. A healthcare provider administered a histamine skin prick, a test traditionally used as a baseline to diagnose allergies. Histamine causes reactions like swelling, rashes, and itching.

Following the skin prick, participants rated how itchy they were on a scale of zero to 100 at 3, 9, 12, 15, and 18 minutes after the skin prick.

Six minutes in, the healthcare provider came back in to check on the participants.

With approximately half of the participants, the provider assured them that “from this point forward your allergic reaction will start to diminish, and your rash and irritation will go away.”

But with the other half of participants (the control group), the provider offered no remarks about their reaction.

The researchers found that when the health care provider offered a few assuring words, the feeling of itchiness declined significantly faster than in participants who were given no explanation about their reaction or recovery.

The biggest difference was 3 minutes after the brief intervention, at 9 minutes in. Assured participants reported their itchiness at an average of 20.19, compared to the control group who rated their irritation at almost 29, on average. The researchers saw that the difference between the two conditions lasted somewhat over time, but shrank as the overall reaction got less itchy.

GETTING WELL SOONER

The authors note in the paper that the study highlights the critical yet rarely quantified healing effect of a physician encouraging patients that they will soon feel better.

“Going to the doctor is largely a psychological experience,” says Crum. “Often we simply want to be reassured that what we are experiencing is ‘normal’ and will go away. And yet, the response we often get is complicated diagnoses, expensive medications, and added uncertainty, all of which may not only fail to harness psychological aspects in healing but may actually generate mindsets that could make us feel worse.”

For Leibowitz, interpersonal interactions are central to what it means to practice medicine, not tangential to it.

Her advice to health care providers is that instead of saying something like “I can’t see anything wrong with you,” physicians could say something like “I think your issue is likely to resolve on its own, and I believe you’ll feel better in a few days,” says Leibowitz.

“There is a growing recognition of the power and importance of these psychological and social forces in health care, and so I hope the system will change to reflect and value things like providing reassurance and setting positive expectations as part of good medicine,” says Leibowitz.

The findings appear in the Journal of General Internal Medicine.
