Do Self-Management Interventions Work in Patients With Heart Failure? An Individual Patient Data Meta-Analysis.

BACKGROUND: Self-management interventions are widely implemented in the care for patients with heart failure (HF). However, trials show inconsistent results, and whether specific patient groups respond differently is unknown. This individual patient data meta-analysis assessed the effectiveness of self-management interventions in patients with HF and whether subgroups of patients respond differently. METHODS AND RESULTS: A systematic literature search identified randomized trials of self-management interventions. Data from 20 studies, representing 5624 patients, were included and analyzed with the use of mixed-effects models and Cox proportional-hazard models, including interaction terms. Self-management interventions reduced the risk of time to the combined end point of HF-related hospitalization or all-cause death (hazard ratio, 0.80; 95% confidence interval [CI], 0.71-0.89), time to HF-related hospitalization (hazard ratio, 0.80; 95% CI, 0.69-0.92), and improved 12-month HF-related quality of life (standardized mean difference, 0.15; 95% CI, 0.00-0.30). Subgroup analysis revealed a protective effect of self-management on the number of HF-related hospital days in patients <65 years of age (mean, 0.70 versus 5.35 days; interaction P=0.03). Patients without depression did not show an effect of self-management on survival (hazard ratio for all-cause mortality, 0.86; 95% CI, 0.69-1.06), whereas in patients with moderate/severe depression, self-management reduced survival (hazard ratio, 1.39; 95% CI, 1.06-1.83, interaction P=0.01). CONCLUSIONS: This study shows that self-management interventions had a beneficial effect on time to HF-related hospitalization or all-cause death and HF-related hospitalization alone and elicited a small increase in HF-related quality of life. The findings do not endorse limiting self-management interventions to subgroups of patients with HF, but increased mortality in depressed patients warrants caution in applying self-management strategies in these patients.

What Are Effective Program Characteristics of Self-Management Interventions in Patients With Heart Failure? An Individual Patient Data Meta-analysis.

BACKGROUND: To identify those characteristics of self-management interventions in patients with heart failure (HF) that are effective in influencing health-related quality of life, mortality, and hospitalizations. METHODS AND RESULTS: Randomized trials on self-management interventions conducted between January 1985 and June 2013 were identified and individual patient data were requested for meta-analysis. Generalized mixed effects models and Cox proportional hazard models including frailty terms were used to assess the relation between characteristics of interventions and health-related outcomes. Twenty randomized trials (5624 patients) were included. Longer intervention duration reduced mortality risk (hazard ratio 0.99, 95% confidence interval [CI] 0.97-0.999 per month increase in duration), risk of HF-related hospitalization (hazard ratio 0.98, 95% CI 0.96-0.99), and HF-related hospitalization at 6 months (risk ratio 0.96, 95% CI 0.92-0.995). Although results were not consistent across outcomes, interventions comprising standardized training of interventionists, peer contact, log keeping, or goal-setting skills appeared less effective than interventions without these characteristics. CONCLUSION: No specific program characteristics were consistently associated with better effects of self-management interventions, but longer duration seemed to improve the effect of self-management interventions on several outcomes. Future research using factorial trial designs and process evaluations is needed to understand the working mechanism of specific program characteristics of self-management interventions in HF patients.

End-of-life preferences of elderly patients with chronic heart failure.

AIMS: Elderly heart failure (HF) patients are assumed to prefer improved quality of life over longevity, but sufficient data are lacking. Therefore, we assessed the willingness to trade survival time for quality-of-life (QoL) and the preferences for resuscitation. METHODS AND RESULTS: At baseline and after 12 and 18 months, 622 HF patients aged ≥60 years (77 ± 8 years, 74% NYHA-class ≥III) participating in the Trial of Intensified vs. standard Medical therapy in Elderly patients with Congestive Heart Failure had prospective evaluation of end-of-life preferences by answering trade-off questions (willingness to accept a shorter life span in return for living without symptoms) and preferences for resuscitation if necessary. The time trade-off question was answered by 555 patients (89%), 74% of whom were not willing to trade survival time for improved QoL. This proportion increased over time (Month 12: 85%, Month 18: 87%, P < 0.001). In multivariable analysis, willingness to trade survival time increased with age, female sex, a reduced Duke Activity Status Index, Geriatric Depression Score, and history of gout, exercise intolerance, constipation and oedema, but even combining these variables did not result in reliable prediction. Of 603 (97%) patients expressing their resuscitation preference, 51% wished resuscitation, 39% did not, and 10% were undecided, with little changes over time. In 430 patients resuscitation orders were known; they differed from patients' preferences 32% of the time. End-of-life preferences were not correlated to 18-month outcome. CONCLUSION: Elderly HF patients are willing to address their end-of-life preferences. The majority prefers longevity over QoL and half wished resuscitation if necessary. Prediction of individual preferences was inaccurate.

Self-reported cardiovascular risk factors in immigrants and Swiss nationals.

OBJECTIVE: The purpose of this study was to investigate whether the prevalence of self-reported cardiovascular risk factors differs between immigrants and Swiss nationals. DESIGN AND SAMPLE: This study is a secondary data analysis of the Swiss Health Survey 2002, a cross-sectional survey. In total, 19,249 individuals living in Switzerland were included. MEASURES: The prevalence of hypertension, high cholesterol level, smoking, diabetes, overweight, low fruit and vegetable intake, and physical inactivity were calculated for major immigrant groups and Swiss nationals. Demographic data were used to control for age and socioeconomic status. RESULTS: Major immigrant groups were people from Italy, Germany, former Yugoslavia, Spain, Portugal, France, and Turkey. Compared with Swiss women, women from former Yugoslavia were more likely to have hypertension, and women from Germany were more likely to have high cholesterol levels. Women from Italy, former Yugoslavia, Spain, Portugal, and Turkey were more likely to show physical inactivity and (except Turkish women) to be overweight. Men from these countries (except Spanish men) were more likely to be overweight than Swiss men. CONCLUSIONS: Differences exist in the prevalence of modifiable cardiovascular risk factors between Swiss nationals and many of the immigrant groups. Age and socioeconomic status could only partly explain the differences.

Swiss Interdisciplinary Management Programme for Heart Failure (SWIM-HF): a randomised controlled trial study of an outpatient inter-professional management programme for heart failure patients in Switzerland.

PRINCIPLES: International guidelines for heart failure (HF) care recommend the implementation of inter-professional disease management programmes. To date, no such programme has been tested in Switzerland. The aim of this randomised controlled trial (RCT) was to test the effect on hospitalisation, mortality and quality of life of an adult ambulatory disease management programme for patients with HF in Switzerland. METHODS: Consecutive patients admitted to internal medicine in a Swiss university hospital were screened for decompensated HF. A total of 42 eligible patients were randomised to an intervention (n = 22) or usual care group (n = 20). Medical treatment was optimised and lifestyle recommendations were given to all patients. Intervention patients additionally received a home visit by a HF-nurse, followed by 17 telephone calls of decreasing frequency over 12 months, focusing on self-care. Calls from the HF nurse to primary care physicians communicated health concerns and identified goals of care. Data were collected at baseline, 3, 6, 9 and 12 months. Mixed regression analysis (quality of life) was used. Outcome assessment was conducted by researchers blinded to group assignment. RESULTS: After 12 months, 22 (52%) patients had an all-cause re-admission or died. Only 3 patients were hospitalised with HF decompensation. No significant effect of the intervention was found on HF related to quality of life. CONCLUSIONS: An inter-professional disease management programme is possible in the Swiss healthcare setting but effects on outcomes need to be confirmed in larger studies.

Which interventions are used by health care professionals to enhance medication adherence in cardiovascular patients? A survey of current clinical practice.

BACKGROUND: Complex medication regimens are often required to manage cardiovascular diseases. As non-adherence, which can have severe negative outcomes, is common among cardiovascular patients, various interventions to improve adherence should be implemented in daily practice. AIM: To assess which strategies cardiovascular nurses and allied health professionals utilize to (1) assess patients' adherence to medication regimen, and (2) enhance medication adherence via educational/cognitive, counseling/behavioral, and psychological/affective interventions. METHOD: A 45-item questionnaire to assess adherence assessment and interventional strategies utilized by health care professionals in daily clinical practice was distributed to a convenience sample of attendants of the 10th Annual Spring Meeting of the European Society of Cardiology Council on Cardiovascular Nursing and Allied Professions conference in Geneva (Switzerland) in March 2010. Respondents not in direct clinical practice were excluded. Descriptive statistics were used to describe practice patterns regarding adherence management. RESULTS: Of 276 distributed questionnaires, 171 (62%) were returned, of which 34 (20%) were excluded as respondents performed no direct patient care. Questioning patients about non-adherence during follow-up was the most frequently reported assessment strategy (56%). Educational/cognitive adherence enhancing interventions were used most frequently, followed by counseling/behavioral interventions. Psychological/affective interventions were less frequently used. The most frequent intervention used was providing reading materials (66%) followed by training patients regarding medication taking during inpatient recovery (48%). Slightly over two-thirds (69%) reported using a combination of interventions to improve patient's adherence. CONCLUSION: Educational interventions are used most in clinical practice, although evidence shows they are less effective than behavioral interventions at enhancing medication adherence.

Complexity in caring for an ageing heart failure population: concomitant chronic conditions and age related impairments.

The complexity of caring for the ageing heart failure (HF) population is further complicated by concomitant chronic conditions (i.e., polypharmacy, depression), age related impairments (i.e., hearing, visual and cognitive impairments, impairments in activities of daily living (ADL/IADL), and other issues (e.g., health illiteracy, lack of social support). This paper provides an overview of these risk factors, outlines how they individually and in interplay endanger favourable outcome by putting patients at risk for poor self-management. Moreover, suggestions are made on how these issues could be addressed and integrated in heart failure management by applying gerontological care principles in caring for the ageing heart failure population.
