A Doctor's Empathy Will Decrease a Patient's Pain More Than Medication Itself


Doctors are often not the most empathetic people due the amount of recurring patterns of complaints they receive on a daily basis. A doctor-patient relationship built on trust and empathy doesn't just put patients at ease -- it actually changes the brain's response to stress and increases pain tolerance, perhaps even more than the medication itself.

Medical researchers have shown in recent studies that doctors who listen carefully have happier patients with better health outcomes, but the underlying mechanism was unknown, said Issidoros Sarinopoulos, professor of radiology at Michigan State University (MSU).

"This is the first study that has looked at the patient-centered relationship from a neurobiological point of view," said Sarinopoulos, the lead researcher. "It's important for doctors and others who advocate this type of relationship with the patient to show that there is a biological basis."

"The relevance and statistical correlations of patient-centered relationships and health outcomes is now part of medical curriculum in many institutions", said Psychologist, Dr. Sophia Tranter. "What we are finding is that a doctor's relationship and orientation towards a patient and their well being correlates to a more signficant degree than even the medication itself."

The study involved randomly assigning patients to one of two types of interview with a doctor before undergoing an MRI scan. In the patient-centered approach, doctors addressed any concerns participants had about the procedure and asked open-ended questions allowing them to talk freely about their jobs, home life and other psychological and social factors affecting health. The other patients were asked only specific questions about clinical information such as their medical history and what drugs they were taking.

As expected, those who had the patient-focused interview reported greater satisfaction and confidence in their doctor in a post interview questionnaire.

The participants then were placed in the MRI scanner and given a series of mild electric shocks, similar to the discomfort of having an IV needle inserted, while looking at a photo of a doctor who they were told was supervising the procedure. The scans measured activity in the anterior insula -- the part of the brain that makes people aware of pain -- in anticipation of the shocks and when they actually occurred.

The brain scans revealed those who had the patient-centered interview showed less activity in the anterior insula when they were looking at a photo of the interviewing doctor than when the doctor in the photo was unknown. Those participants also self-reported less pain when the photos showed the known doctor.

Sarinopoulos said the study had a small sample of just nine women and will need to be replicated on a larger scale.

Dr. Tranter said that larger sample sizes would likely reproduce the results and support smaller studies. "Pilot research projects of this kind involving smaller sample sizes are typicallyy validated on larger scales when large amounts of empirical data support the current evidence," she stated.

"We need to do more research to understand this mechanism," he said, "but this is a good first step that puts some scientific weight behind the case for empathizing with patients, getting to know them and building trust."

Published in the journal Patient Education and Counseling, the study was part of a broader effort at MSU, led by professor of medicine Robert Smith, to establish standards for patient-centered health care and measure its effectiveness.

"Medicine has for too long focused just on the physical dimensions of the patient," said Smith, who co-authored the paper. "Those clinical questions are important and necessary, but we're trying to demonstrate that when you let patients tell their story in an unfettered way, you get more satisfied patients who end up healthier."
