Dermatology is at a trisection of science, art and policy that warrants further study
The medical world is changing; this is fact. Exactly how these changes will translate into practice and affect dermatology is unclear. So unclear, in fact, that many are scrambling to address issues that may or may not be relevant as the model for healthcare delivery is debated on national, state and local levels. This leaves dermatology at the apex of a trisection between science, art and policy that warrants further inquiry.
