Dismantling structural racism as a root cause of racial disparities in COVID-19 and transplantation.
As the United States faces unparalleled challenges due to COVID-19, racial disparities in health and healthcare have once again taken center stage. If effective interventions to address racial disparities in transplantation, including those magnified by COVID-19, are to be designed and implemented at the national level, it is first critical to understand the complex mechanisms by which structural, institutional, interpersonal, and internalized racism influence the presence of racial disparities in healthcare and transplantation. IN this article the authors discuss their viewpoint.

Mechanisms of age and race differences in receiving minimally invasive inguinal hernia repair.
Black patients and older adults are less likely to receive minimally invasive hernia repair. In this study, the investigators explored the association between race, age, and surgeon utilization of minimally invasive surgery (MIS) with the likelihood of receiving MIS inguinal hernia repair. The investigators concluded that race differences were explained by surgeon MIS utilization, implicating access to MIS-performing surgeon as a mediator. Conversely, age disparity was independent of MIS utilization, even after adjusting for comorbidities, indicating some degree of provider bias against performing MIS repair in older patients.

Racial and ethnic disparities in utilization rate, hospital volume, and perioperative outcomes after total knee arthroplasty.
The researchers sought to study racial disparities in the utilization of total knee arthroplasty (TKA), the use of high-volume hospitals, and TKA outcomes, including mortality and complications, using all-payer databases. They found that minorities had lower rates of TKA utilization but higher rates of adverse health outcomes associated with the procedure, even after adjusting for patient-related and health-care system-related characteristics.
