Patient-Physician Race Concordance, Physician Decisions, and Patient Outcomes
利用大型急诊科数据，发现患者与医生种族一致会增加诊疗时间、减少住院和检查，并降低患者再就诊率，效果在轻症和非典型症状患者中更明显。
Abstract Using administrative data from a large and diverse emergency department (ED), we examine the impact of race concordance between patients and physicians on physician decision-making and patient health outcomes. We find that patient-physician race concordance increases consultation time and decreases the probability of inpatient admission and diagnostic testing. Subsequently, race-concordant patients have lower revisit rates after ED discharge. The effect of race concordance is largely driven by patients who had less serious illnesses and whose diseases had nonspecific symptoms or less clear causes. The results are best explained by the informational and communication mechanism.
