A study on doctors says Mississippi remains in last place when it comes to the number of doctors per capita but has seen a sizeable increase in student enrollment. The Clarion-Ledger reported Friday that the Association of American Medical Colleges study shows that medical and osteopathic student enrollment in Mississippi increased 137 percent over the last decade, compared 33 percent nationwide. The state has made a concerted effort in recent years to increase the number of doctors it trains. In 2005 the University of Mississippi's medical school increased enrollment, going from 100 students a year to 145.
