Correlation between medication regimen complexity and quality of life in patients with heart failure.

PURPOSE: To determine if a correlation exists between the medication regimen complexity index (MRCI) and quality of life (QoL) in patients with heart failure (HF) assessed using the Minnesota Living with Heart Failure Questionnaire (MLHFQ). METHODS: Retrospective chart review from July 2012 through June 2018 identified patients for inclusion who completed an MLHFQ. Baseline and, if available, follow-up MLHFQ scores were collected. The medication list documented on the date of the MLHFQ was used to calculate the MRCI. RESULTS: Patients with a documented MLHFQ score were included (n = 72) in the primary analysis. No correlation existed between baseline MRCI and MLHFQ (r = 0.07; p = 0.55). A secondary analysis of correlation between change in MRCI and MLHFQ was conducted for patients (n = 30) with a follow-up MLHFQ score. A moderate, negative correlation (r = -0.47; p = 0.009) existed between change in MRCI and MLHFQ from baseline to follow-up. CONCLUSION: No significant correlation between MRCI and MLHFQ scores were found at baseline. Patients with follow-up MLHFQ scores demonstrated improvements in QoL, despite increasingly complex medication regimens. Medication regimen complexity alone is likely an insufficient marker for predicting QoL in patients with HF.

Impact of Enhanced External Counterpulsation on Heart Failure Rehospitalization in Patients With Ischemic Cardiomyopathy.

Heart failure (HF) affects millions of Americans and causes financial burdens because of the need for rehospitalization. For this reason, health care systems and patients alike are seeking methods to decrease readmissions. We assessed the potential for reducing readmissions of patients with postacute care HF through an educational program combined with enhanced external counterpulsation (EECP). We examined 99 patients with HF who were referred to EECP centers and received heart failure education and EECP treatment within 90 days of hospital discharge from March 2013 to January 2015. We compared observed and predicted 90-day readmission rates and examined results of 6-minute walk tests, Duke Activity Status Index, New York Heart Association classification, and Canadian Cardiovascular Society classification before and after EECP. Patients were treated with EECP at a median augmentation pressure of 280 mm Hg (quartile 1 = 240, quartile 3 = 280), achieved as early as the first treatment. Augmentation ratios varied from 0.4 to 1.9, with a median of 1.0 (quartile 1 = 0.8, quartile 3 = 1.2). Only 6 patients (6.1%) had unplanned readmissions compared to the predicted 34%, p <0.0001. The average increase in distance walked was 52 m (18.4%), and the median increase in Duke Activity Status Index was 9.95 points (100%), p values <0.0001. New York Heart Association and Canadian Cardiovascular Society classes improved in 61% and 60% of the patients, respectively. In conclusion, patients with HF who received education and EECP within 90 days of discharge had significantly lower readmission rates than predicted, and improved functional status, walk distance, and symptoms.
