Heart Failure Patient Adherence

Psychosocial predictors of health behavior adherence in heart-failure patients with comorbid depression: a secondary analysis of the Hopeful Heart trial

BACKGROUND

Depression affects 20-30% of individuals with heart failure (HF), and it is associated with worse health outcomes independent of disease severity. One potential explanation is the adverse impact of depression on HF patients' adherence to the health behaviors needed to self-manage their condition. The aim of this study is to identify characteristics associated with lower adherence in this population, which could help to recognize individuals at higher risk and eventually tailor health behavior interventions to their needs.

METHODS

Using data from a randomized, controlled, collaborative care treatment trial in 629 patients with HF and comorbid depression, we performed mixed effects logistic regression analyses to examine the cross-sectional and prospective relationships between medical and psychosocial variables and health behavior adherence, including adherence to medications, a low-sodium diet, and physician appointments.

RESULTS

In cross-sectional analyses, married marital status and higher physical health-related quality of life (HRQoL) were associated with greater overall adherence (compared to married, single Odds Ratio [OR] = 0.46, 95% Confidence Interval [CI] = 0.26-0.80; other OR = 0.60, CI = 0.38-0.94; p = .012. Physical HRQoL OR = 1.02, CI = 1.00-1.04, p = .047). Prospectively, greater levels of social support were associated with improved overall adherence one year later (OR = 1.04, 95% CI = 1.00-1.08, p = .037). Social support, HF symptom severity, race and ethnicity, and age were predictors of specific types of adherence. Neither depression nor optimism was significantly associated with adherence outcomes.

CONCLUSIONS

These results provide important preliminary information about risk factors for poor adherence in patients with both HF and depression, which could, in turn, contribute to the development of interventions to promote adherence in this high-risk population.

Kinesophobia and its related factors in patients after percutaneous coronary intervention: A cross-sectional study

OBJECTIVES

To explore the postoperative kinesophobia of patients after percutaneous coronary intervention (PCI) and its related factors.

BACKGROUND

Percutaneous coronary intervention is an effective method to treat coronary heart disease (CHD), and cardiac rehabilitation is an important auxiliary method after PCI. However, the compliance of patients with cardiac rehabilitation after PCI is not good, among which kinesophobia is an important influencing factor.

DESIGN

A descriptive cross-sectional design was implemented, and the high-quality reporting of the study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology Statement.

METHODS

In total, 351 inpatients who underwent PCI in three tertiary grade-A hospitals in China were selected by convenient sampling method. We use one-way ANOVA and multiple linear regression analysis to determine the relevant related factors.

RESULTS

The kinesophobia of patients after PCI was negatively correlated with chronic illness resource utilization and sense of personal mastery, and positively correlated with illness perception. Education level, clinical classification of CHD, exercise habits, chronic illness resource utilization, illness perception and sense of personal mastery entered the regression equation, which could explain 78.1% of the total variation.

CONCLUSION

The level of kinesiophobia of patients after PCI is high. Education level, clinical classification of CHD, exercise habits, chronic illness resource utilization, illness perception and sense of personal mastery are the related factors of kinesiophobia of patients after PCI.

RELEVANCE TO CLINICAL PRACTICE

By reducing the level of exercise fear of patients after PCI, patients are more likely to accept and adhere to the cardiac rehabilitation plan, thus improving their prognosis and improving their quality of life.

PATIENT OR PUBLIC CONTRIBUTION

The patient underwent PCI in the research hospital. Researchers screen them according to the inclusion criteria and invite them to participate in this study. If they meet the requirements, participants will answer the research questionnaire face to face after signing the informed consent form.

Cost-effectiveness of an inpatient nurse practitioner in heart failure

AIMS

Heart failure (HF) nurse practitioners (NPs) are an important part of the HF specialist team, and their impact on the cost-effectiveness of their role is unknown. The aim of this study was to determine the cost-effectiveness of a HF NP inpatient service compared with current practice of no HF NP service from a health system perspective at 12 months and 3 years.

METHODS AND RESULTS

We developed a Markov model to estimate costs, effects, and cost-effectiveness for hospitalized HF patients and seen by a HF NP service compared with usual care at 12 months and 3 years. Costs and effects were taken from a retrospective observational cohort study. Transition probabilities and utilities were derived from published studies. A total of 500 patients were included (250 patients in the HF NP service vs. 250 patients in usual care). Average age was 77.7 ± 11 years, and 54% were male. At 12 months, the HF NP group was cheaper and more effective compared with no HF NP [$23 031 vs. $25 111 (AUD), respectively; quality-adjusted life years (QALYs) were 0.68 in HF NP group compared with 0.66 in usual care]. The incremental cost-effectiveness ratio showed a savings of $109 474 per QALY gained at 12 months and a savings of $270 667 per QALY gained at 3 years in favour of the HF NP service.

CONCLUSION

The HF NP service was cost-effective with lower costs and higher QALYs compared with no HF NP service. Economic evaluations alongside randomized controlled trials are warranted.

Factors that predict compliance in a virtual cardiac rehabilitation program

BACKGROUND

Despite the well-established benefits of cardiac rehabilitation (CR) for patients with cardiovascular disease (CVD), participation in CR remain low. Virtual CR programs present a unique opportunity to promote utilization. To date, few virtual CR cohorts have been analyzed for compliance. This study aims to determine factors that predict compliance within a large virtual CR program in the United States.

METHODS

We analyzed 1409 patients enrolled in the Kaiser Permanente Mid-Atlantic States Virtual CR program that consists of 12 CR sessions via telephone. Demographic characteristics, as well as body weight, blood pressure, HbA1c level, and smoking status were collected at admission. Patients were further classified by CVD diagnosis codes. Compliance was defined as at least 75% (9/12 sessions) attendance. Data was analyzed using simple and multiple regression models with significance defined as P < 0.05.

RESULTS

Age was the single strongest predictor for virtual CR compliance (adjusted R2 = 0.58; P < 0.001), and non-compliant patients were younger. HbA1C level, CVD diagnosis codes, and smoking status each moderately predicted compliance (adjusted R2 = 0.48, 0.42, and 0.31, respectively; P < 0.001). Smoking and HbA1C level combined in a multiple regression model significantly improved prediction of compliance (adjusted R2 = 0.79, P < 0.01). Sex, baseline weight or hypertension were not significant predictors of CR compliance.

CONCLUSIONS

Age, diabetes, CVD diagnoses, smoking status at admission are independent predictors of compliance in a large virtual CR program. Targeted intervention could be designed accordingly to improve CR compliance.

Exploring the Need and Benefits of Digital Therapeutics (DTx) for the Management of Heart Failure in India

Indian heart failure (HF) registries consistently indicate high hospital readmissions and increased mortality rates after HF diagnosis. The challenges of Indian cardiologists in HF management include limited longitudinal data, frequent readmissions, low medication adherence, inadequate monitoring and follow-up, insufficient patient education, and lack of standard guidelines on cardiac rehabilitation. This article outlines the adoption of digital therapeutics (DTx) in HF management as a potential solution to address these challenges. DTx services offer improved medication adherence, early symptom identification, remote vital monitoring, timely intervention, patient education on symptoms, self-awareness, and lifestyle. Overall, DTx for HF comprises a dedicated team of cardiologists, health coaches, care managers, and globally certified connected devices to provide comprehensive and proactive monitoring, personalized coaching and support, behavioral engagement to improve adherence, emergency response system, delivery of medications and diagnostic tests at home, and a dedicated application for caregivers. DTx has the potential to enhance HF management in India.

Effectiveness of telemonitoring intervention on glycaemic control in patients with type 2 diabetes mellitus: A systematic review and meta-analysis

BACKGROUND

Type 2 diabetes mellitus (T2DM) is a rising global health concern that requires long-term treatment and close monitoring. Telemonitoring has been shown to be a promising tool to facilitate patient-physician interaction and improve glycaemic control.

METHOD

Randomised controlled trials (RCT) of telemonitoring in T2DM published between 1990 and 2021 were searched through multiple electronic databases. The primary outcome variables included HbA1c and fasting blood glucose (FBG), and BMI was a secondary outcome variable.

RESULTS

Thirty RCT with a total of 4,678 participants were included in this study. Twenty-six studies reported on HbA1c, which was shown to be significantly lower in participants on telemonitoring when compared to conventional care. Ten studies investigated FBG which collectively showed no statistically significant difference. Subgroup analysis demonstrated the effect of telemonitoring on glycaemic control is influenced by a range of factors concerning system practicality, user engagement, patient characteristics and disease education.

CONCLUSION

Telemonitoring exhibited a great potential to improve T2DM management. Several technical features and patient factors may influence the effectiveness of telemonitoring. Further studies are needed to verify the findings and address limitations before its implementation into routine practice.

Factors influencing kinesiophobia during the "blanking period" after radiofrequency catheter ablation in patients with atrial fibrillation by the fear-avoidance model

BACKGROUND

The influencing factors of kinesiophobia (fear of movement) in patients with atrial fibrillation(AF)during the post-operative "Blanking Period" are not known. The aims were to investigate the status of kinesiophobia in patients with AF during the post-operative "Blanking Period", then further describe the occurrence and analyze the influencing factors of patients' kinesiophobia by the Fear-Avoidance Model.

MATERIALS AND METHODS

In total,400 patients diagnosed with atrial fibrillation, during the post-operative "Blanking Period" from the selected hospital were included in this study. The Tampa Scale for Kinesiophobia Heart (TSK-SV Heart), the Self-efficacy for Exercise (SEE) scale, and the Geriatric Locomotive Function Scale (GLFS) were used to assess kinesiophobia, exercise self-efficacy, and physical function. The study adopted a cross-sectional design.

RESULTS

The score of kinesiophobia during the "Blanking Period" after operation in patients with atrial fibrillation was (44.06 ± 10.77), and the rate of high kinesiophobia was 71.61%.Logistic regression results showed that age, education, household monthly income, resting heart rate, EHRA symptom classification, exercise self-efficacy, and physical function influenced the kinesiophobia of patients during the post-operative "Blanking Period"(p<0.05， p<0.01).

CONCLUSIONS

Kinesiophobia is common in patients with atrial fibrillation during the postoperative "Blanking Period", and the fear of movement is related to age, education, household monthly income, resting heart rate, EHRA symptom classification, exercise self-efficacy, and physical function. Clinical and nursing staff should pay close attention to the psychological problems in the post-operation "Blanking Period" of exercise rehabilitation in patients with atrial fibrillation, make timely interventions to reduce patients' fear of movement, and improve patients' compliance with exercise rehabilitation.

Effectiveness and usability of mobile health applications for medication adherence in patients with heart failure: a systematic review protocol

OBJECTIVE

This review will assess the effectiveness and usability of mobile health applications to improve medication adherence in patients with heart failure.

INTRODUCTION

Poor medication adherence by heart failure patients is a major cause of negative clinical outcomes, high rates of hospital readmissions, and death, thereby increasing costs for patients and the health care system. Several studies have shown that the use of mobile health applications improves self-care by heart failure patients, including medication adherence. Therefore, gathering evidence on these studies will help researchers and clinicians understand the impact of such interventions on patient care.

INCLUSION CRITERIA

Eligible studies will evaluate medication adherence in participants aged ≥18 years diagnosed with heart failure who are using app-based (software) interventions. Experimental and observational studies will be included. We will exclude studies with interventions that used mobile applications without functionality to assist the user in organizing and taking their medications.

METHODS

Articles published from database inception to the present day, without language restrictions, will be selected from Embase, MEDLINE, LILACS, Scopus, Web of Science, CINAHL, and the Cochrane Library. Two independent reviewers will screen articles, assess methodological quality, and extract data using JBI assessment and extraction instruments. Discrepancies will be solved by consensus and a third reviewer will be consulted if necessary. A narrative synthesis of findings will be presented, and statistical analysis will be used when appropriate.

Adherence to the Use of Home Telehealth Technologies and Emergency Room Visits in Veterans with Heart Failure

Background: Prior studies have posited poor patient adherence to remote patient monitoring as the reason for observed lack of benefits. Introduction: The purpose of this study was to examine the relationship between average adherence to the daily use of home telehealth (HT) and emergency room (ER) visits in Veterans with heart failure. Materials and Methods: This was a retrospective study using administrative data of Veterans with heart failure enrolled in Veterans Affairs (VA) HT Program in the first half of 2014. Zero-inflated negative binomial regression was used to determine which predictors affect the probability of having an ER visit and the number of ER visits. Results: The final sample size was 3,449 with most being white and male. There were fewer ER visits after HT enrollment (mean ± standard deviation of 1.85 ± 2.8) compared with the year before (2.2 ± 3.4). Patient adherence was not significantly associated with ER visits. Age and being from a racial minority group (not white or black) and belonging to a large HT program were associated with having an ER visit. Being in poorer health was associated with higher expected count of ER visits. Discussion: Subgroups of patients (e.g., with depression, sicker, or from a racial minority group) may benefit from added interventions to decrease ER use. Conclusions: This study found that adherence was not associated with ER visits. Reasons other than adherence should be considered when looking at ER use in patients with heart failure enrolled in remote patient monitoring programs.

Low educational level increases functional disability risk subsequent to heart failure in Japan: On behalf of the Iwate KENCO study group

Objectives

The risk factors that contribute to future functional disability after heart failure (HF) are poorly understood. The aim of this study was to determine potential risk factors to future functional disability after HF in the general older adult population in Japan.

Methods

The subjects who were community-dwelling older adults aged 65 or older without a history of cardiovascular diseases and functional disability were followed in this prospective study for 11 years. Two case groups were determined from the 4,644 subjects: no long-term care insurance (LTCI) after HF (n = 52) and LTCI after HF (n = 44). We selected the controls by randomly matching each case of HF with three of the remaining 4,548 subjects who were event-free during the period: those with no LTCI and no HF with age +/-1 years and of the same sex, control for the no LTCI after HF group (n = 156), and control for the LTCI after HF group (n = 132). HF was diagnosed according to the Framingham diagnostic criteria. Individuals with a functional disability were those who had been newly certified by the LTCI during the observation period. Objective data including blood samples and several socioeconomic items in the baseline survey were assessed using a self-reported questionnaire.

Results

Significantly associated risk factors were lower educational levels (odds ratio (OR) [95% confidence interval (CI)]: 3.72 [1.63–8.48]) in the LTCI after HF group and hypertension (2.20 [1.10–4.43]) in no LTCI after HF group. Regular alcohol consumption and unmarried status were marginally significantly associated with LTCI after HF (OR [95% CI]; drinker = 2.69 [0.95–7.66]; P = 0.063; unmarried status = 2.54 [0.91–7.15]; P = 0.076).

Conclusion

Preventive measures must be taken to protect older adults with unfavorable social factors from disability after HF via a multidisciplinary approach.

Proof-of-concept trial results of the HeartMan mobile personal health system for self-management in congestive heart failure

This study tested the effectiveness of HeartMan-a mobile personal health system offering decisional support for management of congestive heart failure (CHF)-on health-related quality of life (HRQoL), self-management, exercise capacity, illness perception, mental and sexual health. A randomized controlled proof-of-concept trial (1:2 ratio of control:intervention) was set up with ambulatory CHF patients in stable condition in Belgium and Italy. Data were collected by means of a 6-min walking test and a number of standardized questionnaire instruments. A total of 56 (34 intervention and 22 control group) participants completed the study (77% male; mean age 63 years, sd 10.5). All depression and anxiety dimensions decreased in the intervention group (p < 0.001), while the need for sexual counselling decreased in the control group (p < 0.05). Although the group differences were not significant, self-care increased (p < 0.05), and sexual problems decreased (p < 0.05) in the intervention group only. No significant intervention effects were observed for HRQoL, self-care confidence, illness perception and exercise capacity. Overall, results of this proof-of-concept trial suggest that the HeartMan personal health system significantly improved mental and sexual health and self-care behaviour in CHF patients. These observations were in contrast to the lack of intervention effects on HRQoL, illness perception and exercise capacity.

A Personal Health System for Self-Management of Congestive Heart Failure (HeartMan): Development, Technical Evaluation, and Proof-of-Concept Randomized Controlled Trial

Background

Congestive heart failure (CHF) is a disease that requires complex management involving multiple medications, exercise, and lifestyle changes. It mainly affects older patients with depression and anxiety, who commonly find management difficult. Existing mobile apps supporting the self-management of CHF have limited features and are inadequately validated.

Objective

The HeartMan project aims to develop a personal health system that would comprehensively address CHF self-management by using sensing devices and artificial intelligence methods. This paper presents the design of the system and reports on the accuracy of its patient-monitoring methods, overall effectiveness, and patient perceptions.

Methods

A mobile app was developed as the core of the HeartMan system, and the app was connected to a custom wristband and cloud services. The system features machine learning methods for patient monitoring: continuous blood pressure (BP) estimation, physical activity monitoring, and psychological profile recognition. These methods feed a decision support system that provides recommendations on physical health and psychological support. The system was designed using a human-centered methodology involving the patients throughout development. It was evaluated in a proof-of-concept trial with 56 patients.

Results

Fairly high accuracy of the patient-monitoring methods was observed. The mean absolute error of BP estimation was 9.0 mm Hg for systolic BP and 7.0 mm Hg for diastolic BP. The accuracy of psychological profile detection was 88.6%. The F-measure for physical activity recognition was 71%. The proof-of-concept clinical trial in 56 patients showed that the HeartMan system significantly improved self-care behavior (P=.02), whereas depression and anxiety rates were significantly reduced (P<.001), as were perceived sexual problems (P=.01). According to the Unified Theory of Acceptance and Use of Technology questionnaire, a positive attitude toward HeartMan was seen among end users, resulting in increased awareness, self-monitoring, and empowerment.

Conclusions

The HeartMan project combined a range of advanced technologies with human-centered design to develop a complex system that was shown to help patients with CHF. More psychological than physical benefits were observed.

Dietary Sodium Restriction for Heart Failure: A Systematic Review of Intervention Outcomes and Behavioral Determinants

The 1500 mg/d dietary sodium restriction commonly recommended for patients with heart failure has recently been questioned. Poor adherence to sodium-restricted diets makes assessing the efficacy of sodium restriction challenging. Therefore, successful behavioral interventions are needed. We reviewed sodium restriction trials and descriptive studies of sodium restriction to: 1) determine if sodium restriction was achieved in interventions among heart failure patients; and 2) characterize predictors of successful dietary sodium restriction. Among 638 identified studies, 10 intervention trials, and 25 descriptive studies met inclusion criteria. We used content analysis to extract information about sodium restriction and behavioral determinants of sodium restriction. Dietary sodium was reduced in 7 trials; none achieved 1500 mg/d (range 1938-4564 mg/d). The interventions implemented in the interventional trials emphasized knowledge, skills, and self-regulation strategies, but few addressed the determinants correlated with successful sodium restriction in the descriptive studies (eg, social/cultural norms, social support, taste preferences, food access, self-efficacy). Findings suggest that incorporating determinants predictive of successful dietary sodium restriction may improve the success of interventional trials. Without effective interventions to deploy in trials, the safety and efficacy of sodium restriction remains unknown.

Feasibility and preliminary efficacy of a positive psychology-based intervention to promote health behaviors in heart failure: The REACH for Health study

OBJECTIVE

Most patients with heart failure (HF) struggle to adhere to health behaviors, and existing health behavior interventions have significant limitations. We developed a 12-week, phone-delivered, combined positive psychology (PP) and motivational interviewing (MI) intervention to promote well-being and adherence to physical activity, diet, and medications. In this three-arm, randomized trial, we assessed the feasibility, acceptability, and preliminary efficacy of the intervention compared to treatment as usual and MI-alone conditions in 45 patients with HF and suboptimal health behavior adherence.

METHODS

Participants in the PP-MI or MI-alone conditions completed weekly phone sessions for 12 weeks. Those in PP-MI completed weekly PP exercises and set health behavior goals, while those in the MI-alone condition learned about HF-specific health behaviors and identified potential behavior changes. Primary study outcomes were feasibility (sessions completed) and acceptability (0-10 ratings of PP exercise ease and utility). The intervention's impact on psychological and behavioral outcomes was assessed using mixed effects regression analyses.

RESULTS

Participants in the PP-MI condition completed 73% of sessions and rated PP exercises as easy to complete (mean = 7.5 [SD 1.7] out of 10) and subjectively useful (mean = 7.5 [SD 1.6] out of 10). Compared to the control conditions, PP-MI led to medium effect-size improvements in positive affect (Cohen's d = 0.32-0.77), moderate to vigorous physical activity (d = 0.41-0.74), and medication adherence (d = 0.48-0.78).

CONCLUSION

This PP-MI intervention was feasible, well-accepted, and associated with promising improvements in well-being and health behavior outcomes. Larger trials are needed to examine this intervention's impact on health behavior adherence and other important outcomes (NCT03220204).

Home Telehealth Technologies for Heart Failure: An Examination of Adherence Among Veterans

The current retrospective cohort study uses Department of Veterans Affairs (VA) clinical and facility data of Veterans with heart failure enrolled in the VA Home Tele-health (HT) Program. General estimating equations with facility as a covariate were used to model percent average adherence at 1, 3, 6, and 12 months post-enrollment. Most HT patients were White, male, and of older age (mean = 71 years). Average adherence increased the longer patients remained in the HT program. Number of weekly reports of HT use, not having depression, and being of older age were all associated with higher adherence. Compared to White Veterans, Black and other non-White Veterans had lower adherence. These findings identify subgroups of patients (e.g., those with depression, of younger age, non-White) that may benefit from additional efforts to improve adherence to HT technologies. [Journal of Gerontological Nursing, 46(7), 26-34.].

Positive psychological constructs and health behavior adherence in heart failure: A qualitative research study

Psychological well-being may play an important role in health behavior adherence and cardiovascular health, but there has been limited study of well-being in patients with heart failure. In this descriptive qualitative research study, we interviewed 30 patients with heart failure to explore their psychological experiences with heart failure and the perceived associations between positive psychological constructs and adherence to physical activity, diet, and medication recommendations. Interviews were transcribed, then coded in NVivo using directed and conventional content analysis, and the Consolidated Criteria for Reporting Qualitative Research checklist was applied to report our findings. Participants spontaneously reported positive psychological constructs both during an acute phase of illness and 3 months later. Participants most commonly experienced gratitude, acceptance, connectedness, and faith in the setting of heart failure. In contrast, pride, determination, and hope were identified most frequently as playing a role in health behavior adherence. Finally, participants reported a reinforcing relationship between positive constructs and health behavior engagement. These findings suggest that interventions to boost positive constructs have the potential to improve well-being and health behavior adherence in patients with heart failure.

Predictors of Adherence to Self-Care in Rural Patients With Heart Failure

BACKGROUND

The common reality of not following a recommended course of treatment is a major cause of poor health outcomes in patients with heart failure (HF). The purpose of this study was to identify predictors of adherence to HF self-care recommendations in rural HF patients who received an intervention to promote symptom management and self-care.

METHODS

Data from 349 rural HF patients (42% female, 90% Caucasian) randomized to the intervention arms of the study were used. Adherence was measured using the European Heart Failure Self-Care Scale questionnaire, a brief measure that asks patients to report their adherence to a variety of recommended HF symptom management behaviors (ie, daily weight monitoring, when to call the physician, medications, diet, and exercise). The following predictors were tested: age, gender, marital status, education level, depression score (measured using PHQ-9), anxiety score (measured with the Brief Symptom Inventory), and level of perceived control (measured using Control Attitudes Scale-R). Multivariate linear regression was used to test the model.

RESULTS

The model to predict adherence was significant (P < .0001). Of the covariates tested in the regression model, being a male (P = .009), having less anxiety (P = .018), not being depressed (P = .017), and having higher perceived control (P = .003) were predictors of improved self-care score at 3 months.

CONCLUSION

Adherence is a multifaceted and a challenging behavior based on the assumption that the patient agrees with self-care recommendations. These data suggest interventions designed to promote adherence behaviors should include an assessment of gender, anxiety, depression, and perceived control for optimal outcomes.

Cut-Point for Satisfactory Adherence of the Dietary Sodium Restriction Questionnaire for Patients with Heart Failure

BACKGROUND

The low or non-adherence to reduction of sodium intake has been identified as one of the main precipitating factors of heart failure (HF). The Dietary Sodium Restriction Questionnaire (DSRQ) identifies factors that can interfere with adherence to this recommendation. However, there is still no cut-point to define adherence for this questionnaire.

OBJECTIVES

To identify the cut-point for satisfactory adherence to the Brazilian version of the DSRQ, (the Questionário de Restrição de Sódio na Dieta, QRSD).

METHODS

Multicenter study. Patients with HF in outpatient treatment (compensated) and those treated in emergency departments due to acute HF (decompensated) were included. For the cut-point definition, the DSRQ scores were compared between groups. A ROC curve was constructed for each subscale to determine the best point of sensitivity and specificity regarding adherence. A 5% significance level was adopted.

RESULTS

A total of 206 compensated patients and 225 decompensated were included. Compensated patients exhibited scores that showed higher adhesion in all subscales (all p <0.05). Scores ≥ 40 points of a total of 45 for the subscale of Attitude and Subjective Norm; scores ≤ eight of a total of 20 for Perceived Behavioral Control; and ≤ three of a total of 15 for Dependent Behavior Control were indicative of satisfactory adherence.

CONCLUSIONS

Based on the evaluation of patients in these two scenarios, it was possible to determine the cut-point for satisfactory adherence to the reduction of sodium in the diet of patients with HF. Countries with similar culture could use this cut-point, as other researchers could also use the results as a reference for further studies.

Uncertainty and depressive symptoms as mediators of quality of life in patients with heart failure

Uncertainty in illness is regarded as a source of stress in many chronic diseases and is negatively related to health-related quality of life (HRQoL). However, studies on the relationship between uncertainty and HRQoL in patients with heart failure are limited. This study used Mishel's theory of uncertainty in illness to investigate the mediating role of uncertainty in illness and depressive symptoms between symptom distress and HRQoL in patients with heart failure. This study used a cross-sectional correlation design. Participants were recruited by convenience sampling from outpatient services and medical wards of cardiology departments of a medical center in northern Taiwan. Data were collected for uncertainty, depressive symptoms, symptoms distress of heart failure, and HRQoL using self-report questionnaires. Demographics and clinical characteristics were analyzed with descriptive statistics. The mutual effects of disease characteristics, symptom distress, uncertainty in illness, depressive symptoms and HRQoL, as well as the overall model fitness, were analyzed by with structural equation modeling. We collected 147 qualified questionnaires. The mean score for the Mishel Uncertainty in Illness Scale for patients with heart failure was 73.5 (SD = 18.55); 65.3% of participants had a score of ≧13 on the Beck Depressive Inventory-II, indicating mild depression. Uncertainty, depressive symptoms, and HRQoL were directly related to symptom distress. Symptom distress and depressive symptoms were both mediators between uncertainty and depressive symptoms. Depressive symptoms also mediated emotional support and HRQoL. Uncertainty and depressive symptoms were important factors in the pathway between symptom distress and HRQoL for heart failure patients. We suggest providing heart failure patients with tailored interventions for effective self-management of symptoms based on Mishel's theory of uncertainty in illness, which could help control disease symptoms, alleviate uncertainty and depression as well as improve HRQoL.

A Positive Psychology Intervention to Promote Health Behaviors in Heart Failure: A Proof-of-Concept Trial

Patients with heart failure (HF) frequently struggle to adhere to health behaviors, and psychological factors may contribute to nonadherence. We examined the feasibility and acceptability of a 10-week, positive psychology (PP)-based intervention to promote health behavior adherence in patients (N = 10) with mild to moderate HF and suboptimal health behavior adherence. Participants engaged in weekly phone sessions, completed PP exercises (e.g., writing a gratitude letter, using a personal strength), and set goals related to diet, medication adherence, and physical activity. Feasibility was assessed by the number of sessions completed, and acceptability by participant ratings of ease and utility. Preliminary efficacy was measured by changes in psychological and adherence outcomes. The intervention was feasible (87% of exercises completed) and acceptable. Furthermore, in exploratory analyses, the intervention was associated with improvements in psychological and health behavior adherence outcomes. Larger, randomized trials are needed to further investigate the utility of this intervention.

Use of software applications to improve medication adherence and achieve more integrated disease management in heart failure

The treatment and management of heart failure is associated with high mortality rates and treatment costs. Poor medication adherence is a major barrier to improving care and traditional interventions addressing non-adherence have not consistently demonstrated improvement in health care outcomes like readmission. The reasons for non-adherence are complicated and illustrate the broader challenges patients face when managing a complex disease like heart failure. In this review, a digitally enabled heart failure management platform consisting of medical digital tools and software solutions that are designed to be patient-facing and continuously accessed is explored as a way to integrate the multiple components of heart failure care and deliver personalized patient management tools.

A mixed methods study of Tai Chi exercise for patients with chronic heart failure aged 70 years and older

Aims and objectives

This study aimed to evaluate Tai Chi group training among patients with chronic heart failure (CHF) aged 70 years and older.

Background

Physical activity is recommended for CHF treatment. Tai Chi is found to be beneficial to different patient groups, although few studies focus on older patients with CHF.

Design

A mixed methods study. Participants were randomly assigned to Tai Chi training twice a week for 16 weeks (N = 25) or control (N = 20). Quantitative data were collected at baseline, at the end of the training period and 6 months after training, assessing self‐rated fatigue and quality of life, natriuretic peptides and physical performance. Individual qualitative interviews were conducted with participants (N = 10) in the Tai Chi training group.

Results

No statistical differences between the Tai Chi training group and the control group in quality of life or natriuretic peptides was found. After 16 weeks, the training group tended to rate more reduced activity and the control group rated more mental fatigue. Participants in the training group rated increased general fatigue at follow‐up compared with baseline. Qualitative interviews showed that Tai Chi training was experienced as a new, feasible and meaningful activity. The importance of the leader and the group was emphasized. Improvements in balance were mentioned and there was no physical discomfort.

Conclusion

Tai Chi was experienced as a feasible and meaningful form of physical exercise for patients with CHF aged over 70 years despite lack of achieved health improvement. Further investigations, using feasibility and meaningfulness as outcome variables seems to be useful.

An Intervention to Improve Physical Function and Caregiver Perceptions in Family Caregivers of Persons With Heart Failure

Objective: This randomized controlled trial was conducted to determine whether a 12-week home-based aerobic and resistance exercise program would improve physical function and caregiving perceptions among family caregivers (FCGs) of persons with heart failure. Method: Overall, 127 FCGs were randomized to one of three groups: usual care attention control (UCAC), psychoeducation only (PE), and psychoeducation plus exercise (PE + EX). Physical function measures (6-min walk test, handgrip, and upper and lower strength) and caregiving perceptions (Bakas Caregiving Outcomes Scale) were obtained at baseline and at 6 months. Results: FCGs in the PE + EX showed significant improvement in 6-min walk distance (p = .012), handgrip, and lower extremity strength compared with the PE and UCAC groups. The combined group had the greatest improvement in caregiver perceptions (p < .001). Conclusion: FCGs in the PE + EX group improved the most in physical function and caregiver perception outcomes. Directions for future research are provided.

Effect of an orientation group for patients with chronic heart failure: randomized controlled trial

OBJECTIVE

To evaluate the effect of the orientation group on therapeutic adherence and self-care among patients with chronic heart failure.

METHOD

Randomized controlled trial with 27 patients with chronic heart failure. The intervention group received nursing consultations and participated in group meetings with the multi-professional team. The control group only received nursing consultations in a period of four months. Questionnaires validated for use in Brazil were applied in the beginning and in the end of the study to assess self-care outcomes and adherence to treatment. Categorical variables were expressed through frequency and percentage distributions and the continuous variables through mean and standard deviation. The comparison between the initial and final scores of the intervention and control groups was done through the Student's t-test.

RESULTS

The mean adherence in the intervention group was 13.9 ± 3.6 before the study and 4.8 ± 2.3 after the study. In the control group it was 14.2 ± 3.4 before the study and 14.7 ± 3.5 after the study. The self-care confidence score was lower after the intervention (p=0.01).

CONCLUSION

The orientation group does not improve adherence to treatment and self-care management and maintenance and it may reduce confidence in self-care. Registry REBEC RBR-7r9f2m.

Heart Failure: Self-care to Success: Development and evaluation of a program toolkit

The Heart Failure: Self-care to Success toolkit was developed to assist NPs in empowering patients with heart failure (HF) to improve individual self-care behaviors. This article details the evolution of this toolkit for NPs, its effectiveness with patients with HF, and recommendations for future research and dissemination strategies.

Supportive home health care technology for older adults: Attitudes and implementation

Healthcare delivered at home via telehealth technology may save on both individual and societal healthcare costs. Three studies investigated potential attitudinal barriers to home healthcare adoption. Results from the first concerning adults' privacy concerns and mobile device preferences showed that attitudes clustered into 4 factors and that older adults, particularly males, showed less concern than younger adults about privacy. The second and third studies explored comfort with a wearable device and the role of aesthetics over 2-week and 6-month intervals. Results showed that older adults had stable ratings for comfort while wearing a watch device designed to collect data in real time and that aspects of physical comfort predicted use over a six-month time period. Taken together, the studies provide evidence that attitudes about privacy and comfort for wearable health devices are unlikely to be significant barriers to adoption, though first impressions are important for all age groups.

Psychological Determinants of Heart Failure Self-Care: Systematic Review and Meta-Analysis

OBJECTIVE

Psychological distress has been associated with poor outcomes in patients with chronic heart failure (HF), which is assumed to be partly due to poor HF self-care behavior. This systematic review and meta-analysis describes the current evidence concerning psychological determinants of self-care in patients with chronic HF.

METHODS

Eligible studies were systematically identified by searching electronic databases PubMed, PsycINFO, and the Conference Proceedings Citation Index (Web of Science) for relevant literature (1980-October 17, 2014). Study quality was assessed according to the level of risk of bias. Quantitative data were pooled using random-effects models.

RESULTS

Sixty-five studies were identified for inclusion that varied considerably with respect to sample and study characteristics. Risk of bias was high in the reviewed studies and most problematic with regard to selection bias (67%). Depression (r = -0.19, p < .001), self-efficacy (r = 0.37, p < .001), and mental well-being (r = 0.14, p = .030) were significantly associated with self-reported self-care. Anxiety was not significantly associated with either self-reported (r = -0.18, p = .24) or objective self-care (r = -0.04, p = .79), neither was depression associated with objectively measured medication adherence (r = -0.05, p = .44).

CONCLUSIONS

Psychological factors (depression, self-efficacy, and mental well-being) were associated with specific self-care facets in patients with chronic HF. These associations were predominantly observed with self-reported indices of self-care and not objective indices. Methodological heterogeneity and limitations preclude definite conclusions about the association between psychological factors and self-care and should be addressed in future research.

Remote Health Monitoring for Older Adults and Those with Heart Failure: Adherence and System Usability

BACKGROUND

Remote health monitoring technology has been suggested as part of an early intervention and prevention care model. Older adults with a chronic health condition have been shown to benefit from remote monitoring but often have challenges with complex technology. The current study reports on the usability of and adherence with an integrated, real-time monitoring system over an extended period of time by older adults with and without a chronic health condition.

MATERIALS AND METHODS

Older adults 55 years of age and over with and without heart failure participated in a study in which a telehealth system was used for 6 months each. The system consisted of a wireless wristwatch-based monitoring device that continuously collected temperature and motion data. Other health information was collected daily using a weight scale, blood pressure cuff, and tablet that participants used for health surveys. Data were automatically analyzed and summarized by the system and presented to study nurses.

RESULTS

Forty-one older adults participated. Seventy-one percent of surveys, 75% of blood pressure readings, and 81% of daily weight measurements were taken. Participants wore the watch monitor 77% of the overall 24/7 time requested. The weight scale had the highest usability rating in both groups. The groups did not otherwise differ on device usage.

CONCLUSIONS

The findings indicate that a health monitoring system designed for older adults can and will be used for an extended period of time and may help older adults with chronic conditions reside longer in their own homes in partnership with the healthcare system.

Heart Failure as a Newly Approved Diagnosis for Cardiac Rehabilitation: Challenges and Opportunities

Many see the broadened eligibility of cardiac rehabilitation (CR) to include heart failure with reduced ejection fraction (HFrEF) as a likely catalyst to high CR enrollment and improved care. However, such expectation contrasts with the reality that CR enrollment of eligible coronary heart disease patients has remained low for decades. In this review, entrenched obstacles impeding utilization of CR are considered, particularly in relation to potential HFrEF management. The strengths and limitations of the HF-ACTION (Heart Failure-A Controlled Trial Investigating Outcomes of Exercise Training) trial to advance precepts of CR are considered, as well as gaps that this trial failed to address, such as the utility of CR for patients with heart failure with preserved ejection fraction and the conundrum of poor patient adherence.

Age-related medication adherence in patients with chronic heart failure: A systematic literature review

BACKGROUND

Chronic heart failure (CHF) is prevalent among the elderly and is characterized by high mortality and hospitalization rates. Non-adherence to medications is frequent and related to poor clinical outcomes. It is often assumed that older age is related to poorer medication adherence compared with younger age. We analyzed the existing evidence of age as a determinant of medication adherence in patients with CHF.

METHODS

A systematic search of the bibliographic database MEDLINE and all Cochrane databases was performed. Studies were included if they examined medication adherence in adult patients with CHF, evaluated factors contributing to medication adherence, and analyzed the relationship between age and medication adherence. Articles classified as studies with poor quality were excluded.

RESULTS

A total of 1565 titles were found, and ultimately, 17 studies, which provide data for a total of 162,727 patients, were analyzed. Seven studies showed a statistically significant relationship between age and medication adherence: six articles demonstrated that increased age is correlated with higher medication adherence, and one study showed that patients in the age range of 57 to 64 years are affected by non-adherence to angiotensin-converting enzyme inhibitors. Ten studies found no significant relationship.

CONCLUSIONS

The results suggest that older age alone is not related to poorer medication adherence compared with younger patients with CHF. More attention should be paid to younger newly-diagnosed patients with CHF. Future studies are required to explore medication adherence in CHF in different, standardized, and specific age groups and should be sufficiently powered to assess clinical endpoints.

Northern Territory perspectives on heart failure with comorbidities – understanding trial validity and exploring collaborative opportunities to broaden the evidence base

Congestive Heart Failure (CHF) is an ambulatory care sensitive condition, associated with significant morbidity and mortality, rarely with cure. Outpatient based pharmacological management represents the main and most important aspect of care, and is usually lifelong. This narrative styled opinion review looks at the pharmacological agents recommended in the guidelines in context of the Northern Territory (NT) of Australia. We explore the concept of validity, a term used to describe the basis of standardising a particular trial or study and the population to which it is applicable. We aim to highlight the problems of the current guidelines based approach. We also present alternatives that could utilise the core principles from major trials, while incorporating regional considerations, which could benefit clients living in the NT and remote Australia.

Depressive symptoms and spiritual wellbeing in asymptomatic heart failure patients

Depression adversely predicts prognosis in individuals with symptomatic heart failure. In some clinical populations, spiritual wellness is considered to be a protective factor against depressive symptoms. This study examined associations among depressive symptoms, spiritual wellbeing, sleep, fatigue, functional capacity, and inflammatory biomarkers in 132 men and women with asymptomatic stage B heart failure (age 66.5 years ± 10.5). Approximately 32 % of the patients scored ≥10 on the Beck Depression Inventory, indicating potentially clinically relevant depressive symptoms. Multiple regression analysis predicting fewer depressive symptoms included the following significant variables: a lower inflammatory score comprised of disease-relevant biomarkers (p < 0.02), less fatigue (p < 0.001), better sleep (p < 0.04), and more spiritual wellbeing (p < 0.01) (overall model F = 26.6, p < 0.001, adjusted R square = 0.629). Further analyses indicated that the meaning (p < 0.01) and peace (p < 0.01) subscales, but not the faith (p = 0.332) subscale, of spiritual wellbeing were independently associated with fewer depressive symptoms. Interventions aimed at increasing spiritual wellbeing in patients lives, and specifically meaning and peace, may be a potential treatment target for depressive symptoms asymptomatic heart failure.

The adverse consequences of unmet need among older persons living in the community: dual-eligible versus Medicare-only beneficiaries

OBJECTIVE

Our objective is to estimate and compare the prevalence of selected adverse consequences associated with unmet need for assistance among a socioeconomically and medically vulnerable subgroup of the older adult population, those who are dually eligible for Medicare and Medicaid, with those eligible for Medicare only.

METHOD

Using data from the National Health and Aging Trends Study (NHATS), a representative survey of the older Medicare population, we calculated the prevalence of disability-related need for assistance with self-care, household tasks, and mobility activities and the prevalence of adverse consequences of unmet need by dually eligible and Medicare only status.

RESULTS

Over 2 million community-dwelling older persons experienced an adverse consequence due to unmet need for assistance with self-care (e.g., soiled their clothes), over 2 million experienced adverse consequences due to unmet need for assistance with household tasks (e.g., went without groceries), and over 3 million persons experienced at least one adverse consequence of unmet need for assistance with mobility-related activities (e.g., had to stay in bed) in the month prior to the NHATS interview. Dually eligible persons experienced higher rates of 6 of the 11 adverse consequences studied and were more likely to have at least one adverse consequence in all 3 domains than others.

DISCUSSION

Several care models are emerging with the goal of integrating medical care, behavioral health, and long-term services for the dual eligible population. Indicators of adverse consequences of unmet need could be used to monitor the quality and adequacy of such care systems.

A common NOS1AP genetic polymorphism, rs12567209 G>A, is associated with sudden cardiac death in patients with chronic heart failure in the Chinese Han population

BACKGROUND

Variants in NOS1AP associated with cardiac repolarization and sudden cardiac death (SCD) in coronary artery disease have been reported. Whether they are related to mortality and QTc interval in chronic heart failure (CHF) has not been investigated.

METHODS AND RESULTS

A total of 1,428 patients with CHF and 480 control subjects were genotyped for 6 SNPs of NOS1AP, and the genetic associations with mortality as well as QTc interval were analyzed. During a median follow-up period of 52 months, 467 patients (32.70%) died, of which deaths 169 (36.19%) were SCD. The A allele of rs12567209 was associated with greater risk of all-cause death and SCD (hazard ratio [HR] 1.381, 95% confidence interval [CI] 1.124-1.698 [P = .002], and HR 1.645, 95% CI 1.184-2.287 [P = .003], respectively). After adjusting for other risk factors, significant differences remained (HR 1.309, 95% CI 1.054-1.624 [P = .015], and HR 1.601, 95% CI 1.129-2.271 [P = .008]). The A allele was also associated with prolongation of QTc interval by 4.04 ms in the entire population (P = .026).

CONCLUSIONS

The A allele of rs12567209 in NOS1AP may serve as an independent predictor of all-cause death and SCD in patients with CHF, it is also associated with prolonged QTc interval in the Chinese Han population.

The European Heart Failure Self-care Behaviour Scale: new insights into factorial structure, reliability, precision and scoring procedure

OBJECTIVE

To evaluate a new factorial structure of the European Heart Failure Self-care Behaviour Scale 9-item version (EHFScBS-9), and to test its reliability, floor and ceiling effect, and precision. To propose a new 0-100 score with a higher score meaning better self-care.

METHODS

A sample of 1192 Heart Failure (HF) patients (mean age 72 years, 58% male) was enrolled. Psychometric properties of the EHFScBS-9 were tested with confirmative factor analysis, factor score determinacy, determining the floor and ceiling effect, and evaluating the precision with the standard error of measurement (SEM) and the smallest real difference (SRD).

RESULTS

We identified three well-fitting factors: consulting behaviour, autonomy-based adherence, and provider-based adherence (comparative fit index=0.96). Reliability ranged from 0.77 to 0.95. The EHFScBS-9 showed no floor and ceiling effect except for the provider-based adherence which had an expected ceiling effect. The SEM and the SRD indicated good precision of the EHFScBS-9.

CONCLUSION

The new factorial structure of the EHFScBS-9 showed supportive psychometric properties.

PRACTICE IMPLICATIONS

The EHFScBS-9 can be used to compute a total and specific scores for each identified factor. This may allow more detailed assessment and tailored interventions to improve self-care. The new score makes interpretation of the EHFScBS-9 easier.
