"touro middleton is taking over an abandon hospital (I think), so they are starting over from scratch"
Most do schools are not tied to academic hospitals or any hospital at all, while all md schools are (I cannot even think of a single md school that is not tied to at least a community hospital)
OK bro, you need to start actually looking into things before you run your mouth and then make sweeping statements based on things that you yourself admit to not being sure of.
To start, there are a good chunk (not a majority mind you, but not 1/10) DO schools (at least 1/6) that are actually tied (i.e. they own) an "academic" hospital. To be clear, an academic hospital is one tied (let's use your original terminology) to a medical school and/or university system that has with it graduate medical education programs and trains medical students through clinical rotations. Many of the public DO schools have such an affiliation and some of the private schools do as well (mine included). These tend to be osteopathic hospitals, because surprise, they train osteopathic medical students.
To the next subject: All DO schools are
required to be affiliated with osteopathic teaching hospitals. It is part of the requirement for COCA accreditation. This is accomplished via OPTIs. An OPTI is a consortium of osteopathic training institutions/programs, and these include hospitals that host OGME as well as clinical rotations for the affiliated COM's students. So while most schools don't own a teaching hospital, all have affiliations with teaching hospitals, most of which are actually not new, and have been around for a decently long time.
So while, yes it would be nice for every DO school to own its own teaching hospital, if they want, students can and do primarily rotate in established hospitals with GMEs (now some might not want to, and from a historical standpoint there is actual a reason that DOs tend to prefer preceptors in rural areas, but that's a different issue).
Also, don't get me wrong, there are definitely flaws in many aspects of OGME and COM clinical rotations, but after talking to a decent number of new/low-tier MD students, many of them had the same complaints we have about rotations.
