Higher performing hospitals were also found to have higher rates of prescribing for each of the 4 guideline-recommended discharge medications: aspirin (2a), clopidogrel (2b), lipid-lowering agent (2c), and ACE inhibitor (2d). For most therapies (2a, 2b, 2c), an eGFR effect was present in the leading but not the lagging hospital rank groups. An eGFR effect was present in the lagging but not the leading hospital rank groups for ACE inhibitor use (Fig 2d), a pattern consistent with the initial study hypothesis that higher performing hospitals would have higher rates of prescribing at all levels of eGFR, mitigating the pattern of underuse commonly found as eGFR declines.
