“…For example, between 2006 and 2015 only 25% of the over 20,000 MHS beneficiaries requiring colorectal surgery had their operation within the direct care network at an MTF. 85 Furthermore, between 2005 and 2019, only 10% of 292,411 patients requiring pancreatectomies, hepatectomies, esophagectomies, coronary artery bypass grafts, abdominal aortic aneurysm repairs and carotid endarterectomies eligible for MTF care, actually received their care within the MTF. 86 Many of these subspecialists, particularly cardiothoracic surgery, are working at civilian institutions through partnerships or off-duty employment because few MTFs have the appropriate case volume to maintain their skillset.…”
