Primary | To Evaluate Over the Aggregate IMPROVE-HF Practice Sites the Relative Changes in 7 Performance Measures at 24 Months Compared With Baseline and Determine the Number of Performance Measures That Achieved a Relative 20% or Greater Positive Change. | 7 performance measures: angiotensin converting enzyme inhibitor and/or angiotensin II receptor blockers (ACEI/ARB), beta-blokers, aldosterone receptor antagonists, anticoagulation for atrial fibrillation (AF), cardiac resynchronization therapy (CRT-P/CRT-D), cardioverter-defibrillator (ICD/CRT-D), heart failure (HF) education. We first calcuated % of patients who were eligible for a performance measure that were treated by it at baseline and 24 months. We then calculated the relative change as (% treated at 24 months - % treated at baseline)/% treated at baseline. The 95% confidence interval (CI) was calculated and the relative change of each performance measure was evaluated using a z-test for one-sample proportion. The number of performance measures with >= 20% relative improvement was determined. The intervention was considered successful if a relative 20% or greater improvement in at least 2 of the 7 performance measures at 24 months compared with baseline was achieved. |
24 Month | |
Secondary | Observe the Number of Sites That Demonstrate a Relative 20% or Greater Improvement in 2 or More of the 7 Performance Measures at 24 Months as Compared to Baseline in Cohort A. | The number of practices that achieved greater than or equal to 20% improvement in two or more of the 7 performance measures at 24 months as compared to baseline of cohort A is presented. | 24 months | |
Secondary | Observe the Change From Baseline to 24 Months in Each Performance Measure and Composite Score for the Aggregate Practices. | performance measure improvement for each performance measure was analyzed at a practice level from baseline to 24 months. Performance measure adherence was calculated at the individual practice level and then combined and summarized. Mean, standard deviation, and 95% confidence intervals for performance measure adherence, composite score and relative change (24 months compared with baseline) are reported. The Composite Score is based on the ratio of the sum of the numerators of all individual performance measures to the sum of the denominators of all individual performances measures. The numerator of a performance measure is the number of patients treated with that measure. The denomiator of a performance measure is the number of patients eligible for being treated with that measure. |
24 months | |
Secondary | Observe the Relative Change Between Baseline of Cohort A and 6 Months of Cohort B in Performance Measures and Composite Score for the Aggregate Practices. | The relative changes between baseline of cohort A and 6 months of cohort B in performance measures and composite score for the aggregate practices were calculated using mean, standard deviation and 95% CI. | Baseline and 6 Months | |
Secondary | Observe the Relative Change Between Baseline of Cohort A and 18 Months of Cohort C in Performance Measures and Composite Score for the Aggregate Practices. | The relative changes between baseline of cohort A and 18 months of cohort C in performance measures and composite score for the aggregate practices were calculated using mean, standard deviation and 95% CI. | baseline and 18 Months |
