A psychometric evaluation of the four-item version of the Control Attitudes Scale for patients with cardiac disease and their partners

The long-term effect of an m-health tool on self-care in patients with heart failure: a pre-post interventional study with a mixed-method analysis

AIMS

The aims of this study were (i) to evaluate the effects of using an m-health tool on self-care behaviour at 3 and 12 months and (ii) to explore the experiences and perceptions of heart failure (HF) patients about the m-health tool.

METHODS AND RESULTS

In this pre-post interventional study with a mixed-method analysis, 71 patients diagnosed with HF [49% female, mean age 76.7 years, New York Heart Association (NYHA) II 31%, NYHA III 69%] were enrolled and had the m-health tool installed in their home for 1 year. The tool consisted of a pre-programmed tablet including a weighing scale and interactive education about HF self-care. At baseline, and at 3 and 12 months, self-care was assessed using the European Heart Failure Self-care Behaviour (EHFScB-9) Scale, an eight-item self-administered questionnaire assessing the experiences of the m-health tool. The mean EHFScB-9 at baseline was 63.8 ± 2.8 and it improved to 67.6 ± 7.6 after 3 months (P < 0.05). After 1 year, the score had decreased to 63.2 ± 7.1 (P = 0.68). Most patients rated the tool as 'good', both at 3 months (92%) and after 12 months (93%). Some found the system to be unnecessary to some degree, and this number increased between 3 and 12 months (P < 0.001). Most patients felt that m-health increased their feelings of security, and 85% responded that the system increased their family members' sense of security.

CONCLUSION

The m-health tool significantly improved patients' self-care behaviour after 3 months, but this effect did not persist after 1 year. For achieving long-term effects and outcomes, additional and regularly updated self-care support may be needed.

Associations between continuity of care, perceived control and self-care and their impact on health-related quality of life and hospital readmission-A structural equation model

AIM

The aim of this study is to examine whether a conceptual model including the associations between continuity of care, perceived control and self-care could explain variations in health-related quality of life and hospital readmissions in people with chronic cardiac conditions after hospital discharge.

DESIGN

Correlational design based on cross-sectional data from a multicentre survey study.

METHODS

People hospitalized due to angina, atrial fibrillation, heart failure or myocardial infarction were included at four hospitals using consecutive sampling procedures during 2017-2019. Eligible people received questionnaires by regular mail 4-6 weeks after discharge. A tentative conceptual model describing the relationship between continuity of care, self-care, perceived control, health-related quality of life and readmission was developed and evaluated using structural equation modelling.

RESULTS

In total, 542 people (mean age 75 years, 37% females) were included in the analyses. According to the structural equation model, continuity of care predicted self-care, which in turn predicted health-related quality of life and hospital readmission. The association between continuity of care and self-care was partly mediated by perceived control. The model had an excellent model fit: RMSEA = 0.06, 90% CI, 0.05-0.06; CFI = 0.90; TLI = 0.90.

CONCLUSION

Interventions aiming to improve health-related quality of life and reduce hospital readmission rates should focus on enhancing continuity of care, perceived control and self-care.

IMPACT

This study reduces the knowledge gap on how central factors after hospitalization, such as continuity of care, self-care and perceived control, are associated with improved health-related quality of life and hospital readmission in people with cardiac conditions. The results suggest that these factors together predicted the quality of life and readmissions in this sample. This knowledge is relevant to researchers when designing interventions or predicting health-related quality of life and hospital readmission. For clinicians, it emphasizes that enhancing continuity of care, perceived control and self-care positively impacts clinical outcomes.

Self-care perception and behaviour in patients with heart failure: A qualitative and quantitative study

Background and objective

Self‐care strategies in heart failure (HF) are effective for disease management, yet adherence in many patients is inadequate. Reasons are presumably multifactorial but remain insufficiently investigated; thus, we aimed to analyse self‐care adherence and associated factors in outpatients with HF.

Methods and results

To measure self‐care levels and explore barriers and facilitators to self‐care adherence in patients with HF, quantitative study using the European Self‐Care Behaviour Scale (EHFScBS‐9) (n = 80; NYHA II–III, mean age 72 ± 10 years, 58% male) and qualitative study using semi‐structured interviews (n = 32; NYHA II–III, mean age 73 ± 11, 63% male) were conducted. We detected lowest adherence to regular exercise (39%) and contacts with healthcare provider in case of worsening symptoms (47%), whereas adherence was highest for regular medication taking (94%). Using the EHFScBS‐9 standardized cut‐off score ≤ 70, 51% of patients reported inadequate self‐care. Binary logistic regression analysis showed significant influence of education (OR = 0.314, 95% CI: 0.103–0.959) and perceived control (OR = 1.236, 95% CI: 1.043–1.465) on self‐care adequacy. According to the situation‐specific theory of HF self‐care, most commonly reported factors affecting the process of self‐care were knowledge about HF self‐care behaviours (84%), experience with healthcare professionals (84%), beliefs about their expertise (69%) and habits related to medication taking (72%). Among values, working responsibilities (53%) and maintenance of traditions (31%) appeared as the most prevalent socially based values affecting motivation for self‐care. Situational characteristics related to the person (self‐confidence, 53%; adaptive coping strategies, 88%), problem (burdensome breathing difficulties, 56%; co‐morbidities, 81%) and environment (practical support from family/caregivers, 59%; financial difficulties, 50%) were also commonly reported.

Conclusions

Various factors, including health‐related beliefs, habits and socially based values, need to be taken into account when planning self‐care interventions in patients with HF. A patient tailored approach should be based on adequate patient evaluation, taking into consideration the particular personal and social context.

Patients' and Nurses' Experiences and Perceptions of Remote Monitoring of Implantable Cardiac Defibrillators in Heart Failure: Cross-Sectional, Descriptive, Mixed Methods Study

Background

The new generation of implantable cardioverter-defibrillators (ICDs) supports wireless technology, which enables remote patient monitoring (RPM) of the device. In Sweden, it is mainly registered nurses with advanced education and training in ICD devices who handle the arrhythmias and technical issues of the remote transmissions. Previous studies have largely focused on the perceptions of physicians, and it has not been explored how the patients’ and nurses’ experiences of RPM correspond to each other.

Objective

Our objective is to describe, explore, and compare the experiences and perceptions, concerning RPM of ICD, of patients with heart failure (HF) and nurses performing ICD follow-up.

Methods

This study has a cross-sectional, descriptive, mixed methods design. All patients with HF and an ICD with RPM from one region in Sweden, who had transitioned from office-based visits to implementing RPM, and ICD nurses from all ICD clinics in Sweden were invited to complete a purpose-designed, 8-item questionnaire to assess experiences of RPM. The questionnaire started with a neutral question: “What are your experiences of RPM in general?” This was followed by one positive subscale with three questions (score range 3-12), with higher scores reflecting more positive experiences, and one negative subscale with three questions (score range 3-12), with lower scores reflecting more negative experiences. One open-ended question was analyzed with qualitative content analysis.

Results

The sample consisted of 175 patients (response rate 98.9%) and 30 ICD nurses (response rate 60%). The majority of patients (154/175, 88.0%) and nurses (23/30, 77%) experienced RPM as very good; however, the nurses noted more downsides than did the patients. The mean scores of the negative experiences subscale were 11.5 (SD 1.1) for the patients and 10.7 (SD 0.9) for the nurses (P=.08). The mean scores of the positive experiences subscale were 11.1 (SD 1.6) for the patients and 8.5 (SD 1.9) for the nurses (P=.04). A total of 11 out of 175 patients (6.3%) were worried or anxious about what the RPM entailed, while 15 out of 30 nurses (50%) felt distressed by the responsibility that accompanied their work with RPM (P=.04). Patients found that RPM increased their own (173/175, 98.9%) and their relatives’ (169/175, 96.6%) security, and all nurses (30/30, 100%) answered that they found RPM to be necessary from a safety perspective. Most patients found it to be an advantage with fewer office-based visits. Nurses found it difficult to handle different systems with different platforms, especially for smaller clinics with few patients. Another difficulty was to set the correct number of alarms for the individual patient. This caused a high number of transmissions and a risk to miss important information.

Conclusions

Both patients and nurses found that RPM increased assurance, reliance, and safety. Few patients were anxious about what the RPM entailed, while about half of the nurses felt distressed by the responsibility that accompanied their work with RPM. To increase nurses’ sense of security, it seems important to adjust organizational routines and reimbursement systems and to balance the workload.

Associations Among Perceived Control, Depressive Symptoms, and Well-being in Patients With Heart Failure and Their Spouses: A Dyadic Approach

BACKGROUND

High levels of perceived control and lower levels of depressive symptoms are associated with better well-being in both patients with heart failure and their spouses at an individual level. However, there is a knowledge gap about how these individual factors have reciprocal influences on partners' well-being within the patient-spouse dyads.

OBJECTIVE

The aims of this study were to examine dyads of patients with heart failure and their spouses on whether the patients' perceived control over the management of heart failure and depressive symptoms predicts their own and their spouses' physical and emotional well-being and to examine whether patients' perceived control predicts their own and their spouses' depressive symptoms.

METHODS

A total 155 patient-spouse dyads (patients: 75% male, mean age of 71 years, 53% classified as New York Heart Association III; spouses: 75% female, mean age of 69 years) were recruited from 2 hospital-based outpatient heart failure clinics. Participants completed the Control Attitude Scale, the Beck Depression Inventory, and the Short-Form 36. Dyadic data were analyzed using multilevel regression of the actor-partner interdependence model.

RESULTS

Perceived control had an actor effect on emotional well-being only for patients, and there were partner effects of perceived control on emotional well-being for both patients and their spouses. Depressive symptoms exhibited an actor effect on physical and emotional well-being for patients and spouses, but there were no partner effects of depressive symptoms on emotional well-being. Perceived control had partner effects on depressive symptoms for patients and spouses, but an actor effect of depressive symptoms was only found for patients.

CONCLUSION

In an interdependent relationship within the patient-spouse dyads, each dyad member's perceived control influenced their partner's emotional well-being as well as depressive symptoms. The findings suggest development of dyadic interventions that can increase perceived control over the heart condition.

Trajectory of self-care behaviour in patients with heart failure: the impact on clinical outcomes and influencing factors

BACKGROUND

Patients' self-care behaviour is still suboptimal in many heart failure (HF) patients and underlying mechanisms on how to improve self-care need to be studied.

AIMS

(1) To describe the trajectory of patients' self-care behaviour over 1 year, (2) to clarify the relationship between the trajectory of self-care and clinical outcomes, and (3) to identify factors related to changes in self-care behaviour.

METHODS

In this secondary analysis of the COACH-2 study, 167 HF patients (mean age 73 years) were included. Self-care behaviour was assessed at baseline and after 12 months using the European Heart Failure Self-care Behaviour scale. The threshold score of ⩾70 was used to define good self-care behaviour.

RESULTS

Of all patients, 21% had persistent poor self-care behaviour, and 27% decreased from good to poor. Self-care improved from poor to good in 10%; 41% had a good self-care during both measurements. Patients who improved self-care had significantly higher perceived control than those with persistently good self-care at baseline. Patients who decreased their self-care had more all-cause hospitalisations (35%) and cardiovascular hospitalisations (26%) than patients with persistently good self-care (2.9%, p < 0.05). The prevalence of depression increased at 12 months in both patients having persistent poor self-care (0% to 21%) and decreasing self-care (4.4% to 22%, both p < 0.05).

CONCLUSION

Perceived control is a positive factor to improve self-care, and a decrease in self-care is related to worse outcomes. Interventions to reduce psychological distress combined with self-care support could have a beneficial impact on patients decreasing or persistently poor self-care behaviour.

Patients' Experiences of Living with Atrial Fibrillation: A Mixed Methods Study

INTRODUCTION

Awareness of epidemiological and clinical consequences of atrial fibrillation (AF) has increased, as have disease-related costs. Less attention has been paid to patient-related issues, such as understanding how symptoms, different therapies, and lifestyle adjustments affect daily life. We aimed to describe patients' experiences of living with AF.

METHODS

The study design used a parallel convergent mixed methods approach. Patients with AF were included in the SMURF study and referred for catheter ablation. Patients completed questionnaires on symptoms, health-related quality of life, depression, anxiety, and perceived control and were interviewed. The datasets were analysed separately using inductive content analysis and descriptive statistics. Data were merged to obtain a final interpretation.

RESULTS

Nineteen patients were interviewed and 18 completed questionnaires. Twelve of the patients were male, mean age 60 years (45-75 years). Inductive qualitative analysis revealed three categories: (i) symptoms and concerns limiting life, (ii) dimensions of worries, and (iii) strategies for management. The most common symptoms were tiredness, weakness/fatigue, and breathlessness during activities, and the most pronounced negative impacts on health-related quality of life (HRQOL) were physically related, shown in the ASTA questionnaire. The most negative SF-36 scores were found in role limitations due to physical health problems and vitality. HADS revealed five patients with some degree of anxiety and four with some degree of depression. Patients had lower scores on perceived control than perceived helplessness in CAS. Patients' perceived control was higher than their families', and families experienced more helplessness.

CONCLUSIONS

The mixed methods design deepens our understanding of challenges faced by patients. Patients experienced a limited ability to perform activities of daily living due to AF which created different kinds of worries that encouraged the use of various strategies to manage their lives. Healthcare providers need to be aware that relationships between patients and their relatives can change, and therefore they need to be supported and integrated into the care system.

Dyadic effects of type D personality and perceived control on health-related quality of life in cardiac arrest survivors and their spouses using the actor-partner interdependence model

BACKGROUND

There is a lack of knowledge about factors associated with health-related quality of life in cardiac arrest survivors and their spouses. In addition, survivors and spouses are likely to affect each other's health-related quality of life.

AIMS

The aim was to investigate if a distressed personality and perceived control among cardiac arrest survivors and their spouses were associated with their own and their partner's health-related quality of life.

METHODS

This dyadic cross-sectional study used the actor-partner interdependence model to analyse associations between a distressed personality (type D personality), perceived control (control attitudes scale), and health-related quality of life (EQ index and EQ visual analogue scale).

RESULTS

In total, 126 dyads were included in the study. Type D personality and perceived control in cardiac arrest survivors were associated with their own health-related quality of life. In their spouses, a significant association was found for type D personality but not for perceived control. In addition, type D personality and perceived control in survivors were associated with health-related quality of life in their spouses.

CONCLUSIONS

Type D personality and perceived control are factors that might be considered during post cardiac arrest, because of the associations with health-related quality of life in survivors and spouses. More research is needed to test psychosocial interventions in the cardiac arrest population in order to improve health-related quality of life.

Octo- and nonagenarians' outlook on life and death when living with an implantable cardioverter defibrillator: a cross-sectional study

Background

Elderly individuals are increasingly represented among patients with implantable cardioverter defibrillators (ICD), but data describing life with an ICD are scarse among octo- and nonagenarians. Moreover, few studies have reported those elderly patients’ perspective on timly discussions concerning what shock deactivation involves, preferences on battery replacement, and their attitudes about turning off the ICD nearing end-of-life. Consequently, the aim of the study was to describe outlooks on life and death in octo- and nonagenarian ICD-recipients.

Methods

Participants were identified via the Swedish Pacemaker- and ICD-registry, with 229 octo- and nonagenarians (82.0 ± 2.2 years, 12% female) completing the survey on one occasion. The survey involved questions on health and psychological measures, as well as on experiences, attitudes and knowledge of end-of-life issues in relation to the ICD.

Results

The majority (53%) reported their existing health as being good/very good and rated their health status as 67 ± 18 on the EuroQol Visual Analog Scale. A total of 34% had experienced shock(s), 11% suffered from symptoms of depression, 15% had anxiety, and 26% reported concerns related to their ICD. About one third (34%) had discussed their illness trajectory with their physician, with those octo- and nonagenarians being more decisive about a future deactivation (67% vs. 43%, p < .01). A minority (13%) had discussed what turning off shocks would involve with their physician, and just 7% had told their family their wishes about a possible deactivation in the future. The majority desired battery replacement even if they had reached a very advanced age when one was needed (69%), or were seriously ill with a life-threatening disease (55%). When asked about deactivation in an anticipated terminal illness, about one third (34%) stated that they wanted to keep the shocks in the ICD during these circumstances. About one-fourth of the octo- and nonagenarians had insufficient knowledge regarding the ethical aspects, function of the ICD, and practical consequences of withdrawing the ICD treatment in the end-of-life.

Conclusions

Increasing numbers of elderly persons receive an ICD and geriatric care must involve assessments of life expectancy as well as the patient’s knowledge and attitudes in relation to generator changes and deactivation.

Mediation effect of depressive symptoms in the relationship between perceived control and wellbeing in patients with heart failure and their partners

BACKGROUND

As treatment has improved, patients with heart failure live longer, and the care mostly takes place at home with partners providing the main assistance. Perceived control over heart failure is important in managing self-care activities to maintain health in patients and their family. Depressive symptoms are associated with impaired health status in patients with heart failure and their family. However, there is limited knowledge about how depressive symptoms affect the relationship between health status and perceived control over heart failure in patients with heart failure and their cohabiting partners.

AIM

The aim of this study was to examine whether the relationship between perceived control and health status (i.e. mental and physical) was mediated by depressive symptoms in patients with heart failure and their partners.

METHODS

In this secondary data analysis, we included 132 heart failure patients and 132 partners who completed measures of depressive symptoms (the Beck depression inventory II), perceived control (the control attitude scale), and physical and mental health status (the short form-36) instruments. The mediation effect of depression was examined using a series of multiple regression in patients and their family caregivers separately.

RESULTS

We found a mediator effect of depressive symptoms in the relationship between perceived control and mental health status in both patients and partners. The relationship between perceived control and physical health status was mediated by depressive symptoms in the patients, not in the partners.

CONCLUSION

Efforts to improve self-care management and maintenance by targeting perceived control may be more effective if depressive symptoms are also effectively managed.

The Third Time's a Charm: Psychometric Testing and Update of the Atlanta Heart Failure Knowledge Test

BACKGROUND AND OBJECTIVE

Since first being published in 2009, the Atlanta Heart Failure Knowledge Test (AHFKT) has proven a reliable and valid instrument and has been used in multiple studies. Given advances in heart failure (HF) self-care, we proposed to reevaluate the psychometric properties of the AHFKTv2 across these recent studies and update the instrument.

METHODS

Demographic, clinical, and baseline AHFKTv2 data from 4 intervention studies in persons with HF were combined for this analysis (N = 284). The 30 questions of the AHFKT are focused on 5 HF self-care knowledge domains: pathophysiology, nutrition, behavior, medications, and symptoms. Characteristics of the sample were analyzed using descriptive statistics; validity testing with t tests and Mann-Whitney 2-group tests and Pearson r and Spearman ρ correlations; and reliability calculations and factor analysis were performed based on tetrachoric correlations.

RESULTS

Participants were 22 to 84 years of age, 66% were African American, 63% were male, and 94% had New York Heart Association class II to III HF. Mean AHFKT score was 80.6% (±11%). Hypotheses that higher levels of knowledge would be associated with higher education level (t = -2.7, P < .01) and less sodium consumption (ρ = -0.22, P = .03) were validated. Factor analysis revealed 1 general knowledge factor with good reliability, Cronbach's α was .87. Item response analysis identified individual questions requiring review and revision.

CONCLUSION

Comprehensive psychometric evaluation of the AHFKTv2 confirmed its internal consistency reliability and validity and provided direction for production of the AHFKTv3 available for use in research and clinical practice.

Long-term effects of a dyadic psycho-educational intervention on caregiver burden and morbidity in partners of patients with heart failure: a randomized controlled trial

BACKGROUND

Partners of patients with heart failure provide both practical and emotional support. Many partners assume caregiving responsibilities without being aware of the burden related with this role.

OBJECTIVE

Our work has established that a psycho-educational intervention has benefits at 3, but not at 12 months for patients with heart failure. Further we had not described the long-term effects in caregivers. This study aimed to determine the 24-months effects of a dyadic psycho-educational intervention on caregiver burden and morbidity in partners of patients with heart failure and study factors associated with a change in caregiver burden.

DESIGN

A randomized controlled study design, with a follow-up assessment after 24 months.

SETTING AND PARTICIPANTS

Partners to patients with heart failure were recruited from two hospitals in the southeast of Sweden.

INTERVENTION

A three session nurse-led psycho-educational program was tested and included psychosocial support to maintain the partners' physical and mental functions, and perceived control. Several instrument were used to measure caregiver burden, perceived control, physical and mental health, depression and morbidity.

RESULTS

One hundred fifty-five partners were included. There were no significant differences in any index of caregiver burden or morbidity among the partners in the intervention and control groups after 24 months. Overall, the mean total caregiver burden was found to be significantly increased compared to baseline (36 ± 12 vs 38 ± 14, p < 0.05). A younger partner, less comorbidity, higher levels of perceived control, better physical health and less symptoms of depression in patients, and better mental health in the partners were factors associated with absence of increased caregiver burden over time.

DISCUSSION AND CONCLUSION

Our intervention did not significantly decrease caregiver burden or morbidity. Over time, several aspects of burden increased in both groups. To improve outcomes, individualized and targeted interventions might be beneficial. REGISTERED ON CLINICALTRIALS.

Symptom burden, Metabolic profile, Ultrasound findings, Rhythm, neurohormonal activation, haemodynamics and health-related quality of life in patients with atrial Fibrillation (SMURF): a protocol for an observational study with a randomised interventional component

INTRODUCTION

Atrial fibrillation (AF) is the most common cardiac arrhythmia, with an estimated prevalence of 1.5-2%. It is an independent risk factor for ischaemic stroke and is estimated to cause about 20-25% of all stroke cases. AF has a great impact on health-related quality of life (HRQoL); however, one unresolved issue related to AF is the wide variation in its symptoms.

METHODS AND ANALYSIS

The symptom burden, metabolic profile, ultrasound findings, rhythm, neurohormonal activation, haemodynamics and HRQoL in patients with AF (Symptom burden, Metabolic profile, Ultrasound findings, Rhythm, neurohormonal activation, haemodynamics and health-related quality of life in patients with atrial Fibrillation, SMURF) study is a prospective observational, cohort study, with a randomised interventional part. The aim of the study is to investigate, in patients with AF, the relationship between symptom burden and metabolic aspects, atrial function and different neurohormones, and the effect of radiofrequency ablation (RFA). The interventional part of the study will give an insight into the neurohormonal and intracardiac pressure changes directly after initiation of AF. Consecutive patients with symptomatic AF accepted for treatment with RFA for the first time at Linköping University Hospital are eligible for participation. The enrolment started in January 2012, and a total of 200 patients are to be included into the study, with 45 of them being enrolled into the interventional study with initiation of AF. The sample size of the interventional study is based on a small pilot study with 5 patients induced to AF while 2 served as controls. The results indicated that, in order to find a statistically significant difference, there was a need to include 28 patients; for safety reasons, 45 patients will be included.

ETHICS AND DISSEMINATION

The SMURF study is approved by the Regional Ethical Review Board at the Faculty of Health Sciences, Linköping, Sweden. The results will be presented through peer-review journals and conference presentation.

Gender Disparities in Symptoms of Anxiety, Depression, and Quality of Life in Defibrillator Recipients

BACKGROUND

Most patients cope well with an implantable cardioverter defibrillator (ICD), but psychological distress and ICD-related concerns have been reported in about 20% of ICD recipients. Many previous studies have not distinguished between genders.

METHODS

In this nationwide study we compared quality of life, anxiety, and depression symptoms between the genders in ICD recipients, and determined predictors of each of these variables in men and women. All adult Swedish ICD recipients were invited by mail to participate and 2,771 patients (66 ± 12 years) completed standardized measures of quality of life, symptoms of anxiety, and depression. Time since implantation ranged from 1 year to 23 years with a mean of 4.7 ± 3.9.

RESULTS

Women reported worse quality of life (mean index 0.790 vs 0.825) and higher prevalence of anxiety (20.5% vs 14.7%) than did men (P < 0.001 for both comparisons), while there were no differences in symptoms of depression (8.8% vs 8.2%).

CONCLUSIONS

Most ICD recipients report a good quality of life, without emotional distress, but among the minority with distress, women fare worse than men.
