BACKGROUND
Social Determinants of Health (SDoH) have been described by the World Health Organization as the conditions in which individuals are born, live, work, and age. These conditions can be grouped into three interrelated levels, macro-, meso-, and micro-level determinants.
OBJECTIVE
Providing a computable artifact that can link health data t...
Background
The utilization of dermoscopic analysis is becoming increasingly critical for diagnosing skin diseases by physicians and even artificial intelligence. With the expansion of dermoscopy, its vocabulary has proliferated, but the rapid evolution of the vocabulary of dermoscopy without standardized control is counterproductive. We aimed to de...
BACKGROUND
Dermoscopy is a growing field using microscopy to identify skin lesions by dermatologists and primary care physicians. For a given skin lesion, a wide variety of differential diagnoses exist, which may be challenging for inexperienced users to name and understand.
OBJECTIVE
In this study, we describe the creation of the Dermoscopy Diffe...
