Here are the match results for the four medical schools in the state of Florida. I had some difficulty in making this list because Florida State University and the University of South Florida did not list surgery prelims and medicine prelims as a category separate from categorical general surgery or internal medicine. When I calculated the results for the University of Florida and the University of Miami, I included people who were only entering PGY-1's in surgery under the general surgery category. Therefore, the numbers for internal medicine and surgery will be somewhat inflated. I did not, however, include the internships of people who were pursuing PGY-2's such as dermatology and anesthesiology. (Does any of this explanation make sense?)
Using the absolute numbers from each category is misleading as the University of Miami is the largest medical school the state of Florida and will have more people entering most of the fields listed. A more important indicator would be percentages. Someone who is much better at statistics than I am could conceivably run a series of Chi Square tests to determine if there are any statistically significant differences between the lists. From glancing at the percentages, I would guess that the University of Miami has significantly more people entering anesthesiology, ophthalmology, and internal medicine, and has significantly fewer people entering emergency medicine. My guess for the reasons for these discrepancies are:
Anesthesiology---Jackson Memorial Hospital has the largest residency program in anesthesiology in the country and historically takes many University of Miami students. Further, UM students are also required to rotate through anesthesiology before they can graduate.
Ophthalmology---the University of Miami is home to Bascom Palmer Eye Institute, the #1 eye hospital in the country. The hospital certainly has a significant presence on campus and is a driving force for many students who consider ophthalmology. Further, second-year students are required to take a two-week course and dermatology and ophthalmology.
Internal medicine---five out of our six deans are internists. I would imagine that has something to do with it.
Emergency medicine---Jackson Memorial Hospital does not have a residency program in emergency medicine. There is little push for students to enter this field, and those that do are often on their own to pursue it.
