Communication and empathy within the patient-physician relationship among patients with and without chronic pain.

Context: Chronic pain may affect the relationship between patients and their treating physicians.

Objectives: This study was designed to compare four aspects of physician communication and physician empathy reported by patients with chronic pain and in chronic pain-free controls.

Methods: A cross-sectional study was conducted within a national pain research registry from July 2020 through January 2024. Patients with chronic low back pain of greater than 3 months duration were matched to chronic pain-free controls utilizing propensity scores derived from a logistic regression model based on 11 variables that included sociodemographic characteristics, cigarette smoking status, history of comorbid medical conditions, and duration of the current patient-physician relationship. Patients reported on the primary outcomes of physician communication utilizing the Communication Behavior Questionnaire (CBQ) and physician empathy utilizing the Consultation and Relational Empathy (CARE) measure. Group means were compared for each aspect of physician communication (patient participation and patient orientation, effective and open communication, emotionally supportive communication, and communication about personal circumstances) and physician empathy, and Cohen's d statistic was utilized to assess the clinical relevance of between-group differences. Secondary exploratory analyses were also performed to compare patients treated by osteopathic physicians vs. allopathic physicians and to determine whether study group X physician type interaction effects were present.

Results: The 387 patients in each study group were matched within a caliper width of 0.001 on the propensity score. Overall, patients ranged from 21 to 79 years of age (mean, 50.7 years; standard deviation [SD], 15.1 years), and 617 (79.7 %) of them were female. Patients in the chronic pain group reported poorer scores for all aspects of physician communication and physician empathy than the chronic pain-free controls. All between-group differences were clinically relevant. There were no differences in physician communication or physician empathy according to physician type in the exploratory analyses, and study group X physician type interaction effects were not observed.

Conclusions: In this cross-sectional study, patients with chronic pain reported having physicians with poorer communication and less empathy than chronic pain-free controls. Longitudinal research is needed to more clearly determine the temporal relationship between patients' chronic pain and physician communication and physician empathy during medical encounters.
