Abstract

BACKGROUND:

National guidelines recommend heart failure (HF) disease management programs to facilitate adherence to evidence-based practices. This study examined the influence of dedicated HF clinics on delivery of guideline-recommended therapies for cardiology practice outpatients with HF and reduced left ventricular ejection fraction.

METHODS:

IMPROVE HF, a prospective cohort study, enrolled 167 cardiology practices to characterize outpatient management of 15,381 patients with chronic systolic HF. Adherence to guideline-recommended HF therapies was recorded, and the presence of a dedicated HF clinic was assessed by survey. Multivariate models identified contributions to delivery of guideline-recommended HF therapies.

RESULTS:

Of practices, 41.3% had a dedicated HF clinic. Practices with a dedicated HF clinic had greater adherence to 3 of 7 guideline-recommended HF therapy measures: angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (P = .02), beta-blocker (P = .025), and HF education (P = .009). After adjustment, use of a dedicated HF clinic was associated with greater conformity in 2 of 7 measures: cardiac resynchronization therapy (P = .036) and HF education (P = .005) but not angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, beta-blocker, aldosterone antagonist, implantable cardioverter-defibrillator therapy, and anticoagulation for atrial fibrillation.

CONCLUSIONS:

Use of dedicated HF clinics varied in cardiology outpatient practices and was associated with greater use of cardiac resynchronization therapy and HF education but not other guideline-recommended therapies.
