Regarding “NQF to study socio-demographic factors in 30-day readmissions,” I find it ironic and more than a little telling that the motivation behind this study is not to actually improve quality of care. It's to prove to the CMS that safety net hospitals are “disadvantaged” if held to the same readmissions standards used for everyone else, and deserve an adjustment that ensures that they don't lose revenue in the larger effort to improve the quality of care. Interestingly, that's pretty much the same argument made by many inter-city school districts, and largely for the same reason.
It's also reinforcement for the power of money to shape behavior. Spend federal funds to pay for services without any real quality contingency, and you get provision of services that are not tailored to the marketplace. Mediocre results follow.
