Impact of Physician Race on Patient Decision-Making and Ratings of Physicians: a Randomized Experiment Using Video Vignettes.

ABSTRACT:

Background

Studies suggest that black patients have better interactions, on average, with physicians of their own race. Whether this reflects greater "cultural competence" in race-concordant relationships, or other effects of race unrelated to physician behavior, is unclear. It is also unclear if physician race influences patient decision-making.

Objective

To determine whether physician race affects patients' ratings of physicians and decision-making, independent of physician behavior.

Design

Randomized study using standardized video vignettes.

Participants

Primary care patients with coronary risk factors or disease.

Interventions

Each participant viewed one of 16 vignettes depicting a physician reviewing cardiac catheterization results and recommending coronary artery bypass graft (CABG) surgery. Vignettes varied only in terms of physicians' race, gender, age, and communication style (high vs. low patient-centeredness).

Main measures

Participants rated the video physician's communication, interpersonal style, competence, trustworthiness, likability, and overall performance (0-4 Likert scales). They also rated the necessity of CABG (0-5 scale) and whether they would undergo CABG or obtain a second opinion if they were the video patient (0-3 scales).

Key results

Participants included 107 black and 131 white patients (72% participation rate). Black participants viewing a black (vs. white) video physician gave higher ratings on all physician attributes (e.g., overall rating 3.22 vs. 2.34, p < 0.001) and were more likely to perceive CABG as necessary (4.05 vs. 3.72, p = 0.03) and say they would undergo CABG if they were the video patient (2.43 vs. 2.09, p = 0.004). Patient-centered communication style reduced, but did not eliminate, the impact of race concordance. Physician race was not associated with any outcomes among white patients.

Conclusions

Black patients viewed the doctor in a scripted vignette more positively, and were more receptive to the same recommendation, communicated in the same way, with a black vs. white physician. Patient-centered communication reduced but did not eliminate the effect of physician race.

Project description:Importance:Women and black physicians encounter workplace challenges because of their gender and race. It is unclear whether these individuals are assessed with lower patient satisfaction or confidence ratings compared with white male physicians. Objective:To examine whether physician gender and race affect participant ratings in scenarios in which physician competence is challenged. Design, Setting, and Participants:This randomized trial enrolled a geographically diverse sample of 3592 online respondents in the United States who were recruited from 2 crowdsourcing platforms: Amazon Mechanical Turk (n?=?1741) and Lucid (n?=?1851). A 2?×?2 factorial design for the gender and race of simulated physicians was conducted between March 9 and July 25, 2018. Participants were excluded before intervention if they were younger than 18 years, were pregnant, or had a history of cancer or abdominal surgical procedures. Interventions:A clinical vignette was presented to the participant with a picture of the emergency department physician. Participants were randomly assigned to physicians with different gender and race, with 823 assigned to black women, 791 to black men, 828 to white women, and 835 to white men. A contradictory diagnosis from an online symptom checker introduced doubt about the clinical diagnosis. Main Outcomes and Measures:A composite outcome (range, 0-100, with 0 representing low patient confidence and satisfaction and 100 representing the maximum on the composite scale) measured participant (1) confidence in the physician, (2) satisfaction with care, (3) likelihood to recommend the physician, (4) trust in the physician's diagnosis, and (5) likelihood to request additional tests. Results:Among 3277 adult participants, complete data were available for 3215 (median age, 49 years [range, 18-89 years]; 1667 [52%] female; 2433 [76%] white). No significant differences were observed in participant satisfaction and physician confidence for the white male physician control physicians (mean composite score, 66.13 [95% CI, 64.76-67.51]) compared with white female (mean composite score, 66.50 [95% CI, 65.19-67.82]), black female (mean composite score, 67.36 [95% CI, 66.03-68.69]), and black male (mean composite score, 66.96 [95% CI, 65.55-68.36]) physicians. Machine learning with bayesian additive regression trees revealed no evidence of treatment effect heterogeneity as a function of participants' race, gender, racial prejudice, or sexism. Conclusions and Relevance:No significant differences were observed for simulated patients' evaluations of female or black physicians, suggesting that bias in favor of white male physicians is negligible in survey-based measures of patient satisfaction.
