Women now represent over half of medical school matriculants, almost half of residents and fellows, and over a third of practicing physicians nationally. Despite considerable representation among the physician workforce, women are paid 75 cents on the dollar compared with their male counterparts after accounting for specialty, geography, time in practice, and average hours per week worked. This pay gap is significantly greater than the one reported for US women workers as a whole and has shown little improvement over time. While much has been written about the problem, a robust discussion about how to rectify the situation has been missing from the conversation. Closing the Gender Pay Gap in Medicine is the first comprehensive assessment of how cultural expectations and compensation methodologies in medicine work together to perpetuate salary disparities between men and women physicians.
