"Characteristics of disciplined physicians and predictors of disciplinary action for all violations and by type of violation were the main outcome descriptors. Years in practice, black physicians, and
osteopathic graduates were positive predictors for disciplinary action. In contrast, female physicians, international medical graduates, and Hispanic and Asian physicians were less likely to receive disciplinary action compared with male, US allopathic, and white physicians, respectively."
