Are other medical schools doing this?

Yes! There are approximately thirty (30) medical schools doing this, along with the University of Arizona Colleges of Medicine in Phoenix and Tucson, and several have had successful 3-year programs in Primary Care and other specialties for many years. The national support organization/network for the 3-year medical school curriculum is the Colleges of Accelerated Medical Pathway Programs (CAMPP). The University of Arizona College of Medicine-Phoenix is part of this collaborative. See link to the bibliography/research this group has published to date.
