Key result
Quality improvement plans increased left ventricular function assessment from 53% to 65% (p<0.01) and appropriate ACE inhibitor use from 54% to 74% (p<0.01).
Why the study?
Do quality improvement interventions improve the assessment of LV function and use of ACE inhibitors in Medicare beneficiaries hospitalized with congestive heart failure?

A quality improvement project utilizing data feedback, education, and care maps significantly improved guideline-directed assessment and medical therapy for hospitalized heart failure patients.
DeLong et al. (1998) conducted an observational in Congestive heart failure (n=1,602). Quality improvement plans (physician education, critical care maps, standing orders) vs. Baseline performance (pre-intervention) was evaluated on Assessment of left ventricular (LV) function (p=< .01). Quality improvement plans increased left ventricular function assessment from 53% to 65% (p<0.01) and appropriate ACE inhibitor use from 54% to 74% (p<0.01).
