Project description:The Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) is a simple, feasible, and sensitive questionnaire developed in English for assessing the health status (symptoms, function, and quality of life) of patients with heart failure (HF). We aimed to assess the internal consistency and construct validity of the Portuguese version of KCCQ-12. We administered the KCCQ-12, the Minnesota Living Heart Failure (MLHFQ), and the New York Heart Association (NYHA) classification by telephone. Internal consistency was assessed with Cronbach's Alpha (α-Cronbach) and construct validity with correlations to the MLHFQ and NYHA. Internal consistency was high (α-Cronbach = 0.92 for the Overall Summary score and 0.77-0.85 for the subdomains). Construct validity was supported by finding high correlations between the KCCQ-12 Physical Limitation and the Symptom Frequency domains with the physical domain of the MLHFQ (r = -0.70 and r = -0.76, p < 0.001 for both) and the Overall Summary scale with NYHA classifications (r = -0.72, p < 0.001). The Portuguese version of KCCQ-12 has high internal consistency and shows a convergent construct validity with other measures quantifying the health status of patients with chronic HF and can be used confidently in Brazil for research and clinical care.

Project description:BACKGROUND: While generic health status measures quantify the impact of all patients' diseases on their health-related quality of life, disease specific measures focus on only one of the many conditions that a patient may have. If a patient has two diseases with similar clinical manifestations, they may respond differently to a disease-specific instrument if one of their conditions improves while the other worsens or remains stable, thus undermining the instruments in that patient population. We sought empirical evidence of the reliability and validity (including responsiveness) of the Kansas City Cardiomyopathy Questionnaire (KCCQ), a disease-specific measure for heart failure (HF), among HF patients with and without anemia, a condition that has similar symptoms to HF. METHODS: This work used a prospective cohort study of 811 HF outpatients from 58 U.S. centers with a baseline assessment of anemia of whom 698 were followed for 3 months with serial health status measures. RESULTS: Among participants, 268 (33%) were anemic. The construct validity of the KCCQ was supported by showing similar correlations with the New York Heart Association (NYHA) classification in patients with and without anemia (P value for interaction = 0.38). The internal consistency (Cronbach's alpha = 0.92 and 0.93 for anemic and non-anemic patients, respectively) and test-retest reliability (mean 3-month change scores in stable patients = -2.8 [SD = 1.4] and -0.5 [SD = 0.8], P = 0.14) were similar. Estimates of responsiveness were also similar. CONCLUSION: This study provides empirical evidence that the psychometric properties of the KCCQ are similar in patients with or without anemia, a potentially confounding clinical condition in patients with heart failure.

Project description:Patient-reported outcome measures (PROMs) are relevant independent outcomes in heart failure (HF) care and are predictive of subsequent hospitalization and death in HF. The Kansas City Cardiomyopathy Questionnaire (KCCQ) and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) are the 2 most widely adopted PROMs specific to HF. We compared their prognostic abilities in a prospective cohort of HF patients. A prospective cohort of subjects from a single-center registry was analyzed with regard to baseline KCCQ and MLHFQ scores and the outcomes of death, transplant, or left ventricular assist device implantation and hospitalization. A total of 516 subjects with reduced left ventricular ejection fraction (HFrEF) and 151 subjects with preserved left ventricular ejection fraction (HFpEF) were included. Discrimination was assessed using c-statistics based on time-to-event analyses and receiver-operator curves. The additive contribution of MLHFQ was assessed through the change in c-statistic, incremental discrimination index, and category-free net reclassification index. Overall, KCCQ was superior to MLHFQ for predicting death/transplant/ventricular assist device (c-statistic 0.702 [0.666 to 0.738] and 0.658 [0.621 to 0.695] respectively, p value for difference <0.001) and hospitalization (c-statistic 0.640 [0.613 to 0.666] and 0.624 [0.597 to 0.651], respectively, p value for difference 0.022). However, this difference was statistically nonsignificant in the HFpEF group alone. When analyzing the additional prognostic information afforded by adding MLHFQ to KCCQ in the overall, HFrEF, and HFpEF groups there was no significant improvement, although adding KCCQ to MLHFQ did significantly improve risk stratification. Scoring based upon the abbreviated KCCQ-12 did not reduce the prognostic accuracy of KCCQ. In conclusion, KCCQ is more prognostic of death/transplant/left ventricular assist device and hospitalization than MLHFQ in a combined cohort of patients with HFrEF and HFpEF, although the effect in HFpEF was less pronounced. KCCQ should be the preferred PROM for patients with HF if prognostication is a desired goal of using the PROMs.

Project description:IntroductionEvaluation of health status benefits, cost-effectiveness, and value of new heart failure therapies is critical for supporting their use. The Kansas City Cardiomyopathy Questionnaire (KCCQ) measures patients' heart failure-specific health status but does not provide utilities needed for cost-effectiveness analyses. We mapped the KCCQ scores to EQ-5D scores so that estimates of societal-based utilities can be generated to support economic analyses.MethodsUsing data from two US cohort studies, we developed models for predicting EQ-5D utilities (3L and 5L versions) from the KCCQ (23- and 12-item versions). In addition to predicting scores directly, we considered predicting the five EQ-5D health state items and deriving utilities from the predicted responses, allowing different countries' health state valuations to be used. Model validation was performed internally via bootstrap and externally using data from two clinical trials. Model performance was assessed using R2, mean prediction error, mean absolute prediction error, and calibration of observed vs. predicted values.ResultsThe EQ-5D-3L models were developed from 1000 health status assessments in 547 patients with heart failure and reduced ejection fraction (HFrEF), while the EQ-5D-5L model was developed from 3925 patients with HFrEF. For both versions, models predicting individual EQ-5D items performed as well as those predicting utilities directly. The selected models for the 3L had internally validated R2 of 48.4-50.5% and 33.7-45.6% on external validation. The 5L version had validated R2 of 57.7%.ConclusionMappings from the KCCQ to the EQ-5D can yield the estimates of societal-based utilities to support cost-effectiveness analyses when EQ-5D data are not available.

Project description:PurposeHeart failure (HF) is a complex syndrome. Its appropriate management should combine several health measurements. We assessed the relationship between the Kansas City Cardiomyopathy Questionnaire (KCCQ) and the Pocock's clinical score.MethodsWe conducted a prospective registry of HF outpatients. The main outcome was occurrence of death or hospitalization during a 6-month follow-up. A multivariate logistic regression was performed, including the KCCQ overall summary score, the Pocock's clinical score and their interaction in the model.ResultsFrom January 2008 to December 2010, 143 patients were involved. Mean age of patients was 68 years, and 74% were men. KCCQ's overall summary score and Pocock's clinical score were inversely correlated (r = -0.24, p = 0.026). A total of 61 (42.7%) events occurred. There was a high proportion of events (77.8%) in patients with a Pocock's clinical score > 50%, whatever the KCCQ score value. When the KCCQ score was ? 50 %, there was a low increase in risk as the Pocock's clinical score increased (OR 2.0 [0.6; 6.6]). However, when the KCCQ score was between 50 and 75 or ? 75 %, there was a high increase in risk as the Pocock's clinical score increased (OR 6.9 [1.2; 38.9] and OR 7.4 [0.8; 69.7], respectively).ConclusionsPatients with a high Pocock's clinical score are at a high risk of death or hospitalization. For patients with a low Pocock's clinical score, the KCCQ score can identify those at risk of these events.

Project description:PurposeThe purpose of this study is to evaluate potential gender-based differences in interpreting the Kansas City Cardiomyopathy Questionnaire (KCCQ-23) and to explore if there are aspects of health-related quality of life (HRQOL) not captured by the KCCQ-23 that are important to assess in men and/or women with heart failure (HF).MethodsPatients ≥ 22 years of age with clinician-diagnosed HF and left ventricular ejection fraction ≤ 40% were recruited from two academic medical centers to participate in semi-structured concept elicitation and cognitive debriefing interviews. Enrollment was stratified by patient-identified gender (half women/half men). All interviews were conducted over the phone/web and audio recorded. Interviews were transcribed and descriptive qualitative content analysis was used to summarize findings overall and by gender.ResultsTwenty-five adults (56% women) diagnosed with HF participated. The average age was 67 years (range: 25-88). Women attributed a wider variety of symptoms to HF than men. Some participants had difficulty differentiating whether their experiences were due to HF, side effects of their medications, or age. We found very little evidence that participants interpreted KCCQ-23 items differently based on gender.ConclusionsOverall, our findings indicate that interpretation of the KCCQ-23 items were similar in men and women. However, some modifications to items may improve clarity of interpretation for a wide range of patients.

Project description:BackgroundAdvanced heart failure (HF) is characterized by high morbidity and mortality. Conventional therapy may not sufficiently reduce patient suffering and maximize quality of life.ObjectivesThe authors investigated whether an interdisciplinary palliative care intervention in addition to evidence-based HF care improves certain outcomes.MethodsThe authors randomized 150 patients with advanced HF between August 15, 2012, and June 25, 2015, to usual care (UC) (n = 75) or UC plus a palliative care intervention (UC + PAL) (n = 75) at a single center. Primary endpoints were 2 quality-of-life measurements, the Kansas City Cardiomyopathy Questionnaire (KCCQ) overall summary and the Functional Assessment of Chronic Illness Therapy-Palliative Care scale (FACIT-Pal), assessed at 6 months. Secondary endpoints included assessments of depression and anxiety (measured via the Hospital Anxiety and Depression Scale [HADS]), spiritual well-being (measured via the FACIT-Spiritual Well-Being scale [FACIT-Sp]), hospitalizations, and mortality.ResultsPatients randomized to UC + PAL versus UC alone had clinically significant incremental improvement in KCCQ and FACIT-Pal scores from randomization to 6 months (KCCQ difference = 9.49 points, 95% confidence interval [CI]: 0.94 to 18.05, p = 0.030; FACIT-Pal difference = 11.77 points, 95% CI: 0.84 to 22.71, p = 0.035). Depression improved in UC + PAL patients (HADS-depression difference = -1.94 points; p = 0.020) versus UC-alone patients, with similar findings for anxiety (HADS-anxiety difference = -1.83 points; p = 0.048). Spiritual well-being was improved in UC + PAL versus UC-alone patients (FACIT-Sp difference = 3.98 points; p = 0.027). Randomization to UC + PAL did not affect rehospitalization or mortality.ConclusionsAn interdisciplinary palliative care intervention in advanced HF patients showed consistently greater benefits in quality of life, anxiety, depression, and spiritual well-being compared with UC alone.

Project description:BackgroundDespite the growing epidemic of heart failure with preserved ejection fraction (HFpEF), no valid measure of patients' health status (symptoms, function, and quality of life) exists. We evaluated the Kansas City Cardiomyopathy Questionnaire (KCCQ), a validated measure of HF with reduced EF, in patients with HFpEF.Methods and resultsUsing a prospective HF registry, we dichotomized patients into HF with reduced EF (EF≤ 40) and HFpEF (EF≥50). The associations between New York Heart Association class, a commonly used criterion standard, and KCCQ Overall Summary and Total Symptom domains were evaluated using Spearman correlations and 2-way ANOVA with differences between patients with HF with reduced EF and HFpEF tested with interaction terms. Predictive validity of the KCCQ Overall Summary scores was assessed with Kaplan-Meier curves for death and all-cause hospitalization. Covariate adjustment was made using Cox proportional hazards models. Internal reliability was assessed with Cronbach's α. Among 849 patients, 200 (24%) had HFpEF. KCCQ summary scores were strongly associated with New York Heart Association class in both patients with HFpEF (r=-0.62; P<0.001) and HF with reduced EF (r=-0.55; P=0.27 for interaction). One-year event-free rates by KCCQ category among patients with HFpEF were 0 to 25=13.8%, 26 to 50=59.1%, 51 to 75=73.8%, and 76 to 100=77.8% (log rank P<0.001), with no significant interaction by EF (P=0.37). The KCCQ domains demonstrated high internal consistency among patients with HFpEF (Cronbach's α=0.96 for overall summary and ≥0.69 in all subdomains).ConclusionsAmong patients with HFpEF, the KCCQ seems to be a valid and reliable measure of health status and offers excellent prognostic ability. Future studies should extend and replicate our findings, including the establishment of its responsiveness to clinical change.

Project description:Background The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a measure of heart failure (HF) health status. Worse KCCQ scores are common in patients with chronic kidney disease (CKD), even without diagnosed heart failure (HF). Elevations in the cardiac biomarkers GDF-15 (growth differentiation factor-15), galectin-3, sST2 (soluble suppression of tumorigenesis-2), hsTnT (high-sensitivity troponin T), and NT-proBNP (N-terminal pro-B-type natriuretic peptide) likely reflect subclinical HF in CKD. Whether cardiac biomarkers are associated with low KCCQ scores is not known. Methods and Results We studied participants with CKD without HF in the multicenter prospective CRIC (Chronic Renal Insufficiency Cohort) Study. Outcomes included (1) low KCCQ score <75 at year 1 and (2) incident decline in KCCQ score to <75. We used multivariable logistic regression and Cox regression models to evaluate the associations between baseline cardiac biomarkers and cross-sectional and longitudinal KCCQ scores. Among 2873 participants, GDF-15 (adjusted odds ratio 1.42 per SD; 99% CI, 1.19-1.68) and galectin-3 (1.28; 1.12-1.48) were significantly associated with KCCQ scores <75, whereas sST2, hsTnT, and NT-proBNP were not significantly associated with KCCQ scores <75 after multivariable adjustment. Of the 2132 participants with KCCQ ≥75 at year 1, GDF-15 (adjusted hazard ratio, 1.36 per SD; 99% CI, 1.12-1.65), hsTnT (1.20; 1.01-1.44), and NT-proBNP (1.30; 1.08-1.56) were associated with incident decline in KCCQ to <75 after multivariable adjustment, whereas galectin-3 and sST2 did not have significant associations with KCCQ decline. Conclusions Among participants with CKD without clinical HF, GDF-15, galectin-3, NT-proBNP, and hsTnT were associated with low KCCQ either at baseline or during follow-up. Our findings show that elevations in cardiac biomarkers reflect early symptomatic changes in HF health status in CKD patients.

Project description:BackgroundHeart failure is a worldwide health problem that significantly affects patients' physical function and health state. The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a disease-specific patient-reported outcome measure commonly used for the assessment of health states of patients with heart failure. This study aimed to evaluate the psychometric properties of the Japanese version of the KCCQ.MethodsUsing pooled data of 141 Japanese patients with chronic heart failure from three clinical trials, the Japanese version of the KCCQ was evaluated for validity and reliability, with a focus on the clinical summary score (CSS) and its component domains. For construct validity, the associations of baseline KCCQ scores with New York Heart Association (NYHA) class and the EuroQol five-dimension, three-level (EQ-5D-3L) scores at baseline were analyzed. For reliability, internal consistency was assessed using Cronbach's α, and test-retest reliability (reproducibility) was assessed among stable patients. Responsiveness to changes in patients' clinical status was assessed by analyzing score changes between two timepoints among patients whose health states improved.ResultsAmong 141 patients (mean age, 73.7 ± 10.9 years), 76.6% were NYHA class II at baseline. For CSS and its component domains (physical limitations, symptom frequency, and symptom severity), baseline scores were all significantly lower in patients with a higher NYHA class (p < 0.001 for all, Jonckheere-Terpstra test). The physical limitations domain and CSS showed a moderate correlation (Spearman's ρ = - 0.40 to - 0.54) with three functional status-related EQ-5D dimensions (mobility, self-care, and usual activities). The Cronbach's standardized α was high (> 0.70) for all KCCQ domain/summary scores. In the test-retest analysis among 58 stable patients, all domain/summary scores minimally changed by 0.3-4.2 points with intraclass correlation coefficients of 0.65-0.84, demonstrating moderate to good reproducibility, except for the symptom stability domain. Among 44 patients with improved health states, all domain/summary scores except for the symptom stability and self-efficacy domains substantially improved from baseline with a medium to large effect size of 0.62-0.88.ConclusionsThe Japanese version of the KCCQ was demonstrated to be a valid and reliable tool for the assessment of symptoms and physical function of Japanese patients with chronic heart failure.
