Healthcare is now the largest industry in our economy, with more than 14 million medical professionals. From surgeons, dentists, and physicians to certified nurse practitioners and psychopharmacologists, healthcare comprises myriad professions—each with its own sea of confusing abbreviations and subtle, but important, distinctions in levels of training and capabilities.
