The issue of quality improvement in medical education is a huge and important one. It's becoming a very hot topic in the medical education world right now, which means of course that there are resources (i.e. grant money) becoming available to do this type of work.
There are at least 2 issues here:
1) Using quality improvement tools to improve medical education; and
2) Incorporating the teaching of quality improvement science and tools into medical education.
If anyone is curious how students can contribute directly to improving the quality of health care in America, check the CLARION project that is hosted by the University of Minnesota, the IHI collaborative with medical schools, and a recent article in Safety and Quality in Health Care by a few students at the University of Chicago.
