Reward and empathy in the treating clinician: the neural correlates of successful doctor–patient interactions

Abstract

AbstractThe goal of this study was to determine the neural correlates of successful doctor–patient interactions. We performed an experimental neuroimaging study where medical doctors (MDs) performed a treatment task while their brain activation pattern was measured, using functional magnetic resonance imaging (fMRI). MDs (25–37 years old) first performed a standardized clinical exam of a “professional patient”. Unbeknownst to the doctors, the professional patient was a confederate that rated the doctors’ clinical examination using the Consultation And Relational Empathy (CARE) questionnaire, a standardized protocol assessing a clinician’s social interaction during a consultation. After the clinical exam, MDs were placed inside a brain scanner and the patient was placed on a chair next to the MD. MDs performed a treatment task where an analgesic device was used to alleviate the patient’s pain (experimentally induced), while the MD’s brain activity was measured with fMRI. MDs rated their own empathic concern (equivalent of compassion) and personal distress using the Interpersonal Reactivity Index questionnaire. The patient’s rating of CARE was robustly related to the MD’s own ratings of trait empathic concern and to compassion-related and reward-related activation of medial frontal brain regions during treatment. In contrast, there was no relation with MD’s personal distress, nor with activation in regions associated with the aversive component of experiencing empathy. We conclude that a patient’s positive experience of a medical examination is reflected in doctors’ empathic concern and reward-related brain activations during treatment, suggesting that compassion and pleasure are key factors for successful doctor–patient interactions.
