To the Editor: In their article on the effect of physician-owned cardiac hospitals on rates of cardiac surgery, Dr Nallamothu and colleagues1 stated their results “differ somewhat” from the results reported in the Medicare Payment Advisory Commission (MedPAC) 2005 congressionally mandated study on specialty hospitals.2,3 The MedPAC 2005 study looked at data through 2002, while Nallamothu et al analyzed data through 2003. In 2006, MedPAC issued a refined version of its analysis that examined changes in volume through 2004.4
