Objectives: To evaluate an intervention to improve the quality of care of patients with heart failure in managed Medicare and Medicaid plans in North Carolina., Background: Utilization of angiotensin-converting enzyme inhibitors (ACE-I) and beta-adrenergic receptor blockers (BB) in heart failure (HF) patients remains suboptimal despite evidence-based guidelines supporting their use., Methods: Managed care plans identified adult patients with HF during 2000 (preintervention) and from July 1, 2001, through June 30, 2002 (postintervention). Outpatient medical records were reviewed to obtain data regarding type of heart failure, demographics, comorbidities, and therapies. The intervention consisted of guideline summary dissemination, performance audit with feedback, patient-specific chart reminders, and patient activation mailings., Results: We sampled 1613 patients from 5 plans during the preintervention period and 1528 patients during the postintervention period. Assessment of left ventricular function (LVF) increased from 88.2% to 92.5% of patients (P < .0001). Among patients with moderate to severe left ventricular systolic dysfunction, there was no substantive change in treatment with ACE-I or vasodilators, whereas, appropriate treatment with BB increased from 48.3% (with another 11.9% with documented contraindications) to 67.9% (with another 7.5% with documented contraindications). The quality gap decreased from 39.8% to 24.6% (P < .0001)., Conclusion: LVF assessment improved despite high preintervention rates. Treatment rates with ACE-I and vasodilators remained high, but did not improve. Treatment rates with BB improved substantially translating into a significant public health benefit. Health-care payers should consider development of financial incentives to encourage collaborative quality improvement programs.

Background: Heart failure (HF) is a common clinical syndrome resulting in high morbidity and mortality. We examined the spectrum of ventricular dysfunction, and investigated the predictors of angiotensin-converting enzyme (ACE) inhibitor, beta-blocker, and spironolactone prescription in 1613 managed care patients with HF., Methods and Results: The diagnosis of HF was made by a HF discharge diagnosis or at least 3 physician encounters with a HF diagnosis during 2000. Logistic regression was used to identify predictors of medication prescription. Preserved systolic function was documented in 37%, moderate-severe systolic dysfunction in 31%, mild systolic in 14%, and 18% had inadequate documentation. The mean age was 69 years, 58% were women, 24% African American, and 60% were Medicare patients. Patients without HF type documented were the least aggressively treated. Coronary artery disease, hypertension, and diabetes predicted increased utilization of ACE inhibitor and beta-blocker therapies. History of nephropathy was associated with less ACE inhibitor prescription. Advancing age predicted less utilization of beta-blockers and spironolactone. Neither ethnicity nor gender influenced medication prescription., Conclusion: Preserved left ventricular function was common. Documentation of significant systolic dysfunction was associated with improved quality of care. Interventions to encourage documentation of HF type and further study of HF with preserved systolic function are warranted.

Use of angiotensin-converting enzyme (ACE) inhibitors and beta-adrenergic receptor blockers in patients with heart failure (HF) remains low despite the results of clinical trials and evidence-based guidelines that support their use. The quality of HF care in managed Medicare and Medicaid programs in North Carolina participating in a HF quality improvement program was assessed. Managed care plans identified adult patients with 1 inpatient or 3 outpatient claims for HF during 2000. A stratified random sample of 971 Medicare and 642 Medicaid patients' outpatient medical records from 5 plans were reviewed by trained nurse abstractors to obtain data regarding type of HF, demographics, comorbidities, and therapies. Left ventricular function assessment was performed in 88% of patients. Among 494 patients with systolic dysfunction, 86% were appropriately treated with respect to ACE inhibitors (73% prescribed, 13% had a documented contraindication). In contrast, beta-blocker therapy was appropriate in 61% (49% prescribed, 12% contraindication). There were no significant differences in drug use by insurance, gender, race, or age. Ventricular function assessment and ACE inhibitor prescription rates are higher than beta-blocker prescription rates among Medicare and Medicaid managed care patients in North Carolina. Opportunities for improvement remain, particularly for beta-blocker use.
