Starting The Conversation About Healthcare Disparities, Melissa D. Mendez, Sandra Lopez, John H. Washington Iv

HCA Healthcare Journal of Medicine

The Accreditation Council for Graduate Medical Education (ACGME) put forth institutional requirements to implement healthcare disparity education in resident and fellow curricula in an effort to decrease these inequities. Healthcare disparities stem from many different factors. These may include access to care, insurance status, socioeconomic status, health literacy, language barriers, and the way healthcare systems function. These factors may have interactions that lead to poor health outcomes. As researchers and educators, we need to find a way to research these issues in more depth as well as teach these concepts to our resident physicians. Here, we discuss El Paso, Texas, …

Identifying, Addressing, And Eliminating Microaggressions In Healthcare, Tracy Macintosh, Michelle Hernandez, Anuja S. Mehta Jun 2022

Identifying, Addressing, And Eliminating Microaggressions In Healthcare, Tracy Macintosh, Michelle Hernandez, Anuja S. Mehta

HCA Healthcare Journal of Medicine

Microaggressions are pervasive throughout society, including in healthcare and academic institutions. They are often unconscious but accumulate over time, and they negatively impact the recipients' productivity and achievement by creating a sense of inadequacy as well as a lack of belonging. We outline several evidence-based strategies and teaching frameworks that institutions and training programs can adopt to reduce the prevalence and impact of microaggressions against trainees from historically marginalized groups, and that can promote psychological safety for everyone.

HCA Healthcare Journal of Medicine

Klippel-Trénaunay syndrome is a rare genetic disorder that typically presents as a triad of symptoms consisting of venous malformations (varicosities), capillary malformations (port-wine stain), and limb overgrowth. We followed a 23-year-old African American male with a past medical history of peripheral vascular disease, who was visiting the dermatology clinic for a persistent skin lesion on his thigh. During physical examinations, we noted a subtle port-wine stain on his right leg, right leg hypertrophy, and peripheral vascular disease. Skin findings were difficult to observe on his darker skin tone, Fitzpatrick skin type VI, which may have led to the delayed diagnosis …

Presentations Of Cutaneous Disease In Various Skin Pigmentations: Cutaneous Abscesses, Christopher M. Wong, Christian J. Scheufele, Sandhya Bodapati, Daniel A. Nguyen, Ashleigh E. Hermann, Jean Elizze M. Charles, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Cutaneous abscesses are collections of pus resulting from skin and soft tissue bacterial infections. They clinically exhibit the four cardinal inflammatory signs of pain, warmth, swelling, and erythema. In patients with darkly pigmented skin, classically-associated erythema may be challenging to appreciate and can lead to missed or delayed diagnosis. We compare abscess presentations in different skin types. Recognition of varying presentations of cutaneous abscesses in diverse skin colors will help clinicians utilize additional clues to identify and diagnose this entity correctly.

Presentations Of Cutaneous Disease In Various Skin Pigmentations: Plaque Psoriasis, Ashleigh E. Hermann, Daniel A. Nguyen, Christopher M. Wong, Christian J. Scheufele, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Recent studies estimate that more than 8 million Americans have psoriasis. The prevalence of psoriasis in African Americans is 1.5% compared to 3.6% of Caucasians. Psoriasis is likely to be underdiagnosed among African Americans and other individuals with darker pigmented skin due to variations in clinical presentation in addition to disease distribution and severity. We present images of psoriasis vulgaris in a variety of Fitzpatrick skin types. Differences in the biology of skin pigmentation may explain the clinical masking of erythema in darker-skinned individuals. Recognition of this important difference will help clinicians utilize additional clues to identify and diagnose this …
