What influences physical activity in people with heart failure? A qualitative study

What are the experiences of people with heart failure regarding participation in physical activity? A systematic review, meta-aggregation and development of a logic model

OBJECTIVES

To (1) synthesise the experiences of people with heart failure and those who care for them concerning participation in physical activity (2) develop a logic model for a future intervention which will support people with heart failure to feel confident and safe in being physically active.

DESIGN

A systematic review and meta-aggregation using Joanna Briggs Institute (JBI) methodology.

DATA SOURCES

MEDLINE, Emcare and PsycINFO databases were searched through until June 2024 inclusively.

ELIGIBILITY CRITERIA

Studies with a qualitative design, including qualitative components of mixed-methods studies, which describe experiences of participation in physical activity by adults with chronic heart failure.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers used standardised methods to search and screen studies. Data extraction included the PROGRESS-Plus items. The JBI checklist for qualitative studies was applied. Meta-aggregation guided by JBI methods was used to synthesise the data. This evidence, along with input from a patient and public involvement group, healthcare professionals and charity organisations, was used to develop a logic model.

RESULTS

We included 28 papers (25 studies) comprising 14 qualitative studies and 11 mixed-method studies describing the perspectives of 483 people with heart failure, 64 carers and 12 healthcare professionals.The meta-aggregation produced seven synthesised findings describing the impact of physical symptoms, emotional factors, extrinsic factors, access to knowledge, self-motivation and peer/professional motivation and the positive impact of physical activity. The PROGRESS-PLUS tool identified significant inclusivity issues within the studies. The meta-aggregation with relevant contributor input informed behavioural determinants and potential intervention components of a logic model.

CONCLUSIONS

This study identifies behavioural determinants that underlie the actions of people with heart failure in their relationship with physical activity and potential intervention components for a novel intervention design to support this population. There is a lack of studies exploring health professionals' and carers' perspectives on this topic.

'Working me to life': longitudinal perceptions from adults with heart failure with preserved ejection fraction enrolled in an exercise training clinical trial

AIMS

Adults with heart failure with preserved ejection fraction (HFpEF) responded more favourably to an exercise intervention compared with those with reduced ejection fraction. This study explores factors that contributed to this response, focusing on the qualitative perceptions of adults with HFpEF enrolled in an exercise intervention.

METHODS AND RESULTS

This qualitative descriptive study is a secondary analysis of longitudinal interviews collected at 3, 6, 12, and 18 months from participants with HFpEF enrolled in a randomized controlled trial testing an intervention to promote adherence to exercise. We included participants with at least two interviews. Interviews were examined across and within participants and time points using thematic analysis. Analyses included 67 interviews from 21 adults with HFpEF enrolled in the intervention arm. The sample consisted of 52% (11/21) males and over 47% (10/21) non-White participants. Mean age at enrolment was 63.7 ± 9.9 years. We identified four major themes: (1) overcoming negative attitudes, barriers, and injury, (2) motivations to exercise, (3) exercise-the panacea for HFpEF symptoms and quality of life, and (4) advice for others with HFpEF.

CONCLUSION

Our findings suggest that for many adults with HFpEF, initial hesitancy, fear, and negative attitudes about exercise can be overcome. Exercise coaching using social cognitive constructs, medical fitness centre memberships, and heart rate self-monitoring are successful strategies of engaging adults with HFpEF in long-term unsupervised exercise training.

Comparing physical therapist clinical specialists to experienced nonspecialists on physical activity education for patients with heart failure: A modified retrospective cohort study

Background and Aims

The purpose of this study was to compare the knowledge and practices of specialist and experienced nonspecialist physical therapists in performing patient education about physical activity with patients with heart failure (HF).

Methods

Responses on a nationwide anonymous online survey were used to compare specialist and experienced nonspecialist physical therapists on knowledge and frequency of providing physical activity related education to patients hospitalized with acutely decompensated HF. Responses to survey items were scored on 5-point scales ranging from "Strongly agree" to "Strongly disagree" or "Always" to "Never." Mann-Whitney U statistics were used to compare specialist and experienced nonspecialist responses and Wilcoxon signed-ranks tests were used to examine the gap between knowledge and practice.

Results

Twenty-seven specialists and 43 experienced nonspecialists completed the survey. Both groups were similar in age, and experience treating patients hospitalized with acutely decompensated HF. Both groups "strongly agree" that they had the required knowledge and skills to educate patients with HF on the physical activity topics. However, specialists more often than experienced nonspecialists provided education on topics such as how to monitor vital signs during physical activity ("most of the time" vs. "about half of the time") that promoted patient confidence and safety during exercise. Specialists demonstrated a smaller gap between knowledge and frequency of providing patient education than experienced nonspecialists on three of the four patient education topics.

Conclusion

Specialist physical therapists treating patients with HF in the inpatient hospital setting provided patient education on physical activity at a level more closely matching their skills and the clinical practice guideline than did experienced nonspecialists. Physical therapy clinical specialists practicing in the inpatient hospital setting may improve patient outcomes and lower costs to the health care system by improving physical activity adherence and thereby may reduce avoidable hospital readmissions.

Psychological factors associated with exercise self-efficacy in the recipients of an implantable cardioverter defibrillator

BACKGROUND

Insufficient exercise affects the health of patients who have implantable cardioverter defibrillators (ICD). The purpose of this study was to investigate the correlations between exercise self-efficacy (ESE) and its associated psychological factors in ICD recipients.

METHODS

This cross-sectional study included individuals who had undergone ICD implantation at the cardiology department of a medical centre in Taiwan. A face-to-face survey was conducted. The survey questionnaire included questions regarding the participants' demographics, perceived health (PH), ICD shock-related anxiety (ICD-SRA), self-care self-efficacy (SSE), perceived exercise benefit (PE-benefit), perceived exercise barrier (PE-barrier), and ESE. Data were analysed using SPSS 20.0 Software. Stepwise multiple regression analyses were also performed to evaluate the predictive effects of the aforementioned factors on ESE.

RESULTS

A total of 52 ICD recipients were enrolled. ESE was negatively correlated with ICD-SRA (r = -0.511; p < 0.01) and PE-barrier (r = -0.563; p < 0.01), but positively correlated with SSE (r = 0.339; p < 0.05) and PE-benefit (r = 0.464; p < 0.01). The stepwise multiple regression analysis revealed that PE-barrier, PE-benefit, and ICD-SRA effectively predicted ESE in the participants.

CONCLUSIONS

ESE may be improved by overcoming PE-barrier, ICD-SRA and enhancing PE-benefit. Consequently, improving ESE may enhance the health benefits of exercise.

Revitalizing the Gut Microbiome in Chronic Kidney Disease: A Comprehensive Exploration of the Therapeutic Potential of Physical Activity

Both physical inactivity and disruptions in the gut microbiome appear to be prevalent in patients with chronic kidney disease (CKD). Engaging in physical activity could present a novel nonpharmacological strategy for enhancing the gut microbiome and mitigating the adverse effects associated with microbial dysbiosis in individuals with CKD. This narrative review explores the underlying mechanisms through which physical activity may favorably modulate microbial health, either through direct impact on the gut or through interorgan crosstalk. Also, the development of microbial dysbiosis and its interplay with physical inactivity in patients with CKD are discussed. Mechanisms and interventions through which physical activity may restore gut homeostasis in individuals with CKD are explored.

Physical activity changes and related factors in chronic heart failure patients during the postdischarge transition period: a longitudinal study

BACKGROUND

Physical activity (PA) is essential and effective for chronic heart failure (CHF) patients. A greater understanding of the longitudinal change in PA and its influencing factors during the postdischarge transition period may help create interventions for improving PA. The aims of this study were (1) to compare the change in PA, (2) to examine the influencing factors of PA change, and (3) to verify the mediating pathways between influencing factors and PA during the postdischarge transition period in CHF patients.

METHODS

A total of 209 CHF patients were recruited using a longitudinal study design. The Chinese version of the International Physical Activity Questionnaire (IPAQ), Patient-reported Outcome Measure for CHF (CHF-PRO), and the Chinese version of the Tampa Scale for Kinesiophobia Heart (TSK-Heart) were used to assess PA, CHF-related symptoms, and kinesiophobia. The IPAQ score was calculated (1) at admission, (2) two weeks after discharge, (3) two months after discharge, and (4) three months after discharge. Two additional questionnaires were collected during admission. Generalized estimating equation (GEE) models were fitted to identify variables associated with PA over time. We followed the STROBE checklist for reporting the study.

RESULTS

The PA scores at the four follow-up visits were 1039.50 (346.50-1953.00) (baseline/T1), 630.00 (1.00-1260.00) (T2), 693.00 (1-1323.00) (T3) and 693.00 (160.88-1386.00) (T4). The PA of CHF patients decreased unevenly, with the lowest level occurring two weeks after discharge, and gradually improving at two and three months after discharge. CHF-related symptoms and kinesiophobia were significantly associated with changes in PA over time. Compared with before hospitalization, an increase in CHF-related symptoms at two weeks and two months after discharge was significantly associated with decreased PA. According to our path analysis, CHF-related symptoms were positively and directly associated with kinesiophobia, and kinesiophobia was negatively and directly related to PA. Moreover, CHF-related symptoms are indirectly related to PA through kinesiophobia.

CONCLUSION

PA changed during the postdischarge transition period and was associated with CHF-related symptoms and kinesiophobia in CHF patients. Reducing CHF-related symptoms helps improve kinesiophobia in CHF patients. In addition, the reduction in CHF-related symptoms led to an increase in PA through the improvement of kinesiophobia.

What motivates heart transplantation patients to exercise and engage in physical activity? A network analysis

AIMS

After heart transplantation (HTx), increments in physical activity (PA) are strongly recommended. However, participation rates in exercise-based cardiac rehabilitation and engagement in PA are insufficient in many patients. Hence, this study aimed to explore the central factors and the interconnections among distinct types of motivation to exercise, PA, sedentary time, psychosomatic, diet, and activity limitation characteristics in post-HTx patients.

METHODS AND RESULTS

This is a cross-sectional study involving 133 post-HTx patients (79 men, mean age 57 ± 13 years, mean time from transplantation 55 ± 42 months) recruited from an outpatient clinic in Spain. The patients were asked to fill in questionnaires measuring self-reported PA, motivation to exercise, kinesiophobia, musculoskeletal pain, quality of sleep, depression, functional capacity, frailty, sarcopenia risk, and diet quality. Two network structures were estimated: one network including PA and one network including sedentary time as nodes. The relative importance of each node in the network structures was determined using centrality analyses. According to the strength centrality index, functional capacity and identified regulation (subtypes of motivation to exercise) are the two most central nodes of the network (strength: z-score = 1.35-1.51). Strong and direct connections emerged between frailty and PA and between sarcopenia risk and sedentary time.

CONCLUSION

Functional capacity and autonomous motivation to exercise are the most promising targets of interventions to improve PA levels and sedentary time in post-HTx patients. Furthermore, frailty and sarcopenia risk were found to mediate the effects of several other factors on PA and sedentary time.

The Impact of Resilience, Health Literacy, and Social Support on Medication Adherence and Self-care Among Adults With Heart Failure

BACKGROUND

Personal and psychological factors, such as depression, have a considerable influence on nonadherence to medications and self-care in those with heart failure. More evidence is needed about positive personal factors that motivate adherence to medications and self-care in those with heart failure.

OBJECTIVE

The purpose of this study was to investigate whether there was a relationship between the personal resources of resilience, hope, health literacy, social support, and self-care activation and adherence to HF self-care and medications and whether race impacts adherence.

METHODS

This study used a cross-sectional, correlational design. Stepwise regression was used to test whether resilience, hope, health literacy, self-care activation, and race significantly predicted medication adherence and self-care. A diverse sample was recruited for this study.

RESULTS

Of the 174 participants, 51% were female, 51.7% were White, and the mean age was 62 years. After adjustment for differences in age and depressive symptoms, a predictive relationship remained between resilience, health literacy, and medication adherence. Hope, activation, and race were not selected in the final regression model. A high level of perceived social support was the only predictor of better HF self-care.

CONCLUSION

Persons with heart failure may have better medication adherence and overall self-care if sufficiently resilient, health literate, and supported regardless of their degree of hope or activation. Race and age may be important factors to consider. More research is needed to understand the connection between resilience and medication adherence.

Organizational Learning in Healthcare Contexts after COVID-19: A Study of 10 Intensive Care Units in Central and Northern Italy through Framework Analysis

The rapid spread of the SARS-CoV-2 virus has forced healthcare organizations to change their organization, introducing new ways of working, relating, communicating, and managing to cope with the growing number of hospitalized patients. Starting from the analysis of the narratives of healthcare workers who served in the intensive care units of 10 hospitals in Central and Northern Italy, this contribution intends to highlight elements present during the pandemic period within the investigated structures, which are considered factors that can influence the birth of organizational learning. Specifically, the data collected through interviews and focus groups were analyzed using the framework analysis method of Ritchie and Spencer. The conducted study made it possible to identify and highlight factors related to aspects of communication, relationships, context, and organization that positively influenced the management of the health emergency, favoring the improvement of the structure. It is believed that the identification of these factors by healthcare organizations can represent a valuable opportunity to rethink themselves, thus becoming a source of learning.

Informing behaviour change intervention design using systematic review with Bayesian meta-analysis: physical activity in heart failure

Embracing the Bayesian approach, we aimed to synthesise evidence regarding barriers and enablers to physical activity in adults with heart failure (HF) to inform behaviour change intervention. This approach helps estimate and quantify the uncertainty in the evidence and facilitates the synthesis of qualitative and quantitative studies. Qualitative evidence was annotated using the Theoretical Domains Framework and represented as a prior distribution using an expert elicitation task. The maximum a posteriori probability (MAP) for the probability distribution for the log OR was used to estimate the relationship between physical activity and each determinant according to qualitative, quantitative, and qualitative and quantitative evidence combined. The probability distribution dispersion (SD) was used to evaluate uncertainty in the evidence. Three qualitative and 16 quantitative studies were included (N = 2739). High pro-b-type natriuretic peptide (MAP = -1.16; 95%CrI: [-1.21; -1.11]) and self-reported symptoms (MAP = - 0.48; 95%CrI: [ -0.40; -0.55]) were suggested as barriers to physical activity with low uncertainty (SD = 0.18 and 0.19, respectively). Modifiable barriers were symptom distress (MAP = -0.46; 95%CrI: [-0.68; -0.24], SD = 0.36), and negative attitude (MAP = -0.40; 95%CrI: [-0.49; -0.31], SD = 0.26). Modifiable enablers were social support (MAP = 0.56; 95%CrI: [0.48; 0.63], SD = 0.26), self-efficacy (MAP = 0.43; 95%CrI: [0.32; 0.54], SD = 0.37), positive physical activity attitude (MAP = 0.92; 95%CrI: [0.77; 1.06], SD = 0.36).

The Role of Exercise-based Cardiac Rehabilitation in Heart Failure

Exercise-based cardiac rehabilitation (EBCR) is a treatment modality for patients with heart failure (HF) that has withstood the test of time. It has continued to show benefits even in the current era of pharmacotherapeutics for HF. Participation in a multidisciplinary comprehensive EBCR programme reduces mortality and morbidity, has a multitude of physiological benefits, and improves cardiovascular risk factor control and quality of life. Despite this, historical barriers to enrolment and uptake remain. Strategies to overcome these, as well as alternative delivery methods of EBCR in HF patients, are emerging and include telerehabilitation, focus on special groups and emphasis on behavioural change. This review provides oversight on the modalities of exercise training in HF as well as their benefits and gives an overview of barriers to the utilisation of EBCR along with future progress in the field.

A Web-Based Mind-Body Intervention (Mindful Steps) for Promoting Walking in Chronic Cardiopulmonary Disease: Insights From a Qualitative Study

Background

Given the deleterious effects of physical inactivity in persons with chronic obstructive pulmonary disease (COPD) and/or heart failure (HF), interventions that promote long-term daily physical activity are needed. Mindful Steps, designed to promote walking behaviors in COPD and HF, is a multicomponent intervention that integrates mind-body content with other self-regulatory components. The aim of the current qualitative study was to characterize participants' experiences with Mindful Steps and understand the perceived influence of the intervention on walking and health.

Method

In the context of a pilot randomized controlled feasibility trial comparing the year-long Mindful Steps program to usual care among individuals with COPD and HF, semi-structured qualitative interviews were administered at 6- and 12-months. Interviews were audio recorded and transcribed. The constant comparative method was used to code transcripts, identify categories, and develop interrelated themes.

Results

Nineteen participants (63% female; Mage = 70.2 years, SD = 6.95) who were randomized to the intervention group completed the 6-month interview and 17 completed the 12-month interview. The pedometer with feedback, live group classes, and mind-body videos were described as the most helpful intervention components. Participants learned several strategies that helped their walking (e.g., breathing regulation and awareness, body awareness, mind-body techniques, pacing), described walking as enjoyable, and identified internal reasons for walking (e.g., to feel good). They also reported several physical and mental health benefits of the intervention. Some participants reported limited influence of the intervention on walking or health. Many participants continued to use the strategies they learned in the first half of the intervention at 12-months.

Conclusions

The mind-body content of Mindful Steps appeared to positively influence walking behaviors. Participants' experiences with the intervention helped to identify areas for future intervention refinement. Future quantitative work is needed to corroborate these qualitative findings and assess the efficacy of the intervention on long-term physical activity engagement.

Physical Activity Readiness in Patients with Heart Failure

The aim of this study was to explore the readiness for physical activity (PA) and its related factors in patients with heart failure. This cross-sectional study included 163 patients with heart failure (mean age 66 ± 16, 50% female). The ability to safely engage in PA was assessed with the PA Readiness Questionnaire (PAR-Q). Psychological readiness was measured using two questionnaires, namely: Exercise Self-efficacy Scale and the Motivation for PA and Exercise/Working Out. A multivariate analysis of covariance was conducted to test the effect of background variables on readiness for PA. 64% (n = 105) of patients reported not being able to safely engage in PA, 80% (n = 129) reported low self-efficacy, and 45% (n = 74) were extrinsically motivated indicating external factors drove their motivation. Factors that positively influenced the PA readiness included lower age (p < 0.01), being male (p < 0.01), being married (p < 0.01), having higher education (p < 0.01), being in NYHA-class I compared with II (p < 0.01), less time since diagnosis (p < 0.01), lower BMI (p = 0.02), and not suffering from COPD (p = 0.02). Prior to recommending exercise, assessment of safety to engage in PA along with self-efficacy and motivation in patients with heart failure is essential.

Effects of Replacing Sedentary Time With Physical Activity on Mortality Among Patients With Heart Failure: National Health and Nutrition Examination Survey Follow-Up Study

A sedentary lifestyle is prevalent among patients with heart failure (HF) and is associated with poor prognosis and survival, possibly owing to the displacement of health-enhancing behaviors, such as physical activity (PA). However, there is limited evidence examining the displacement effects of reducing duration of sedentary time (ST) on clinical outcomes in patients with HF. The current study examined the theoretical effects of relocating ST with PA on all-cause and cardiovascular disease (CVD)-specific mortality risks in patients with HF. We analyzed 265 patients with HF who participated in the National Health and Nutrition Examination Survey from 2003 to 2006. Cox proportional hazards regression model was fitted to estimate mortality risks based on objectively measured ST well as time spent in light-intensity PA (LPA) and moderate- and vigorous-intensity PA (MVPA). The theoretical changes in the hazard ratio (HR) by replacing ST with LPA or MVPA were examined using isotemporal substitutional modeling. On average, patients with HF spent 70% of waking hours per day in ST (9.01 hours), followed by LPA (29%; 3.75 hours) and MVPA (1%; 0.13 hours). Ten-minute substitution of ST with LPA was associated with significantly lower all-cause and CVD-specific mortality risks (hazard ratio [HR]=0.93 for both). The mortality risks progressively decreased as more ST was relocated to LPA. The relocation effects of ST with MVPA were not statistically significant, possibly because of limited MVPA accrued in this clinical population. The current study provides empirical evidence about the potential health benefits of replacing a modest amount of ST with LPA among patients with HF.

Perceived barriers and enablers influencing physical activity in heart failure: A qualitative one-to-one interview study

In heart failure (HF), increased physical activity is associated with improved quality of life, reduced hospitalisation, and increased longevity and is an important aim of treatment. However, physical activity levels in individuals living with HF are typically extremely low. This qualitative study with one-to-one interviews systematically explores perceived clinical, environmental, and psychosocial barriers and enablers in older adults (≥70 years old) living with HF. Semi-structured interviews (N = 16) based on the Theoretical Domains Framework elicited 39 belief statements describing the barriers and enablers to physical activity. Theoretical domains containing these beliefs and corresponding constructs that were both pervasive and common were deemed most relevant. These were: concerns about physical activity (Beliefs about Consequences), self-efficacy (Beliefs about Capabilities), social support (Social Influences), major health event (Environmental Context and Resources), goal behavioural (Goal), action planning (Behavioural Regulation). This work extends the limited research on the modifiable barriers and enablers for physical activity participation by individuals living with HF. The research findings provide insights for cardiologists, HF-specialist nurses, and physiotherapists to help co-design and deliver a physical activity intervention more likely to be effective for individuals living with HF.

"I Can't Go Far": Perceptions and Experiences of Heart Failure Patients Regarding Physical Activity: A Qualitative Study Using Semistructured Face-to-Face Interviews

BACKGROUND

Participation in regular physical activity (RPA) is beneficial to the quality of life and life expectancy of patients with chronic heart failure (CHF). However, it is inadequate in many patients.

AIMS

To determine the factors that influence the practice of RPA in patients with CHF managed in general practice.

METHOD

This was a qualitative study using semistructured, individual face-to-face interviews. Patients with CHF (New York Heart Association Stages 1-3) capable of participating in RPA were enrolled by their general practitioner. A longitudinal and transversal inductive thematic analysis was performed by two researchers.

RESULTS

Five themes emerged from the 19 interviews that were conducted. Poor knowledge of the disease and the benefits of participating in RPA, as well as the lack of motivation or enjoyment, in particular due to the absence of previous participation, were considered significant obstacles. Fear associated with CHF or other comorbidities was also an obstacle. Attendance at a rehabilitation center, family and social circles, and having a pet all appeared to be beneficial. Family and friends were important for motivating the patient to participate in an activity but could also be an obstacle when they were overprotective.

CONCLUSION

This study helps highlight the difficulties for patients with CHF associated with participation in RPA. Despite the obstacles, there are enabling factors on which the general practitioner may rely to motivate their patients.

Dynamic factor analysis of seasonal variation in daily physical activity in individuals with heart failure and implanted cardiac devices

BACKGROUND

The purpose of the present study was to determine the presence and magnitude of seasonal variation in daily physical activity (PA) in those with heart failure (HF).

METHODS

Retrospective study and dynamic factor analysis (DFA) of Patient Activity data from Medtronic implanted cardioverter defibrillator and cardiac resynchronization devices (ICD/CRTs).

RESULTS

In a data set of 435 patients, distinct states/trends were identified by DFA including a classic, sinusoidal pattern of seasonal variation and a pattern of decline over the course of 12 months, which were associated with specific clinical characteristics. Overall, model fitting was good.

CONCLUSIONS

Those with low comorbidities, better NYHA Class, higher BMI, no hospitalization, and male sex demonstrated greater seasonal variation of at least 40 min per day between winter (lowest PA) and spring/summer (highest PA). Those with female sex and hospitalization demonstrated overall downward trajectories of approximately 40 and 80 min, respectively, over the course of the year.

Maintaining physical activity following myocardial infarction: a qualitative study

Background

Outcomes following myocardial infarction (MI) are improved by uptake and maintenance of physical activity (PA), but little is understood regarding patients experience of maintaining an active lifestyle once immediate support, such as cardiac-rehabilitation (CR), has ended.

Aim

The purpose of this study was to investigate MI survivors’ attitude and appraisal towards PA and the perceived barriers, motivators and facilitators for maintaining PA long-term.

Methods

Semi-structured interviews were carried out with 18 adults (mean age 60.5, range 37–73 years) from England and Scotland, who were a minimum of 5 months post-MI (mean 29 months, range 5–122 months). There were comparatively more male participants (n = 13, 72 %) than female (n = 5, 28 %). Overall 12 (67 %) participants had attended CR. The interviews were transcribed verbatim and thematic analysis was performed using qualitative data analysis software NVivo.

Results

Data analysis indicated that the following four core themes influenced MI survivors’ behaviour and attitude towards PA: (1) MI as a teachable moment for behaviour change, (2) affective response to MI: enjoyment versus fear, (3) cognitive response to MI: self-perception, attitude and self-efficacy, and (4) access to support and resources, including PA facilities and social support. Participants highlighted a lack of available guidance on maintaining PA behaviour change following CR and that advice on the frequency and intensity of exercise to follow was often unclear and confusing. Feelings of vulnerability and fear of overexertion were apparent, affecting participants self-efficacy to exercise.

Conclusions

Current CR programmes fail to address PA belief systems and perceptions of self-efficacy to exercise. Interventions that address feelings of vulnerability and fear of overexertion may be beneficial. Providing ongoing PA advice and access to social support may facilitate patients to maintain changes in PA.

Modulation of startle and heart rate responses by fear of physical activity in patients with heart failure and in healthy adults

Fear of physical activity (FoPA) has been suggested as a barrier to physical activity in patients with heart failure and might be associated with low adherence to exercise regimen despite medical guideline recommendations. The present study examined physiological indicators of FoPA by assessing startle modulation (via EMG at the orbicularis oculi muscle) and heart rate responses (derived from ECG) after affective priming with lexical stimuli of positive, neutral, and negative valence, as well as words related to physical activity as potentially phobic cues. After screening for FoPA in patients with heart failure and healthy adults, twenty participants each were assigned to one of three subsamples: a healthy control group and two cardiac patient groups scoring either low or high on FoPA. The high-FoPA group showed startle potentiation and more pronounced heart rate acceleration (than did controls) in the phobic prime condition, indicating defensive response mobilization. Among the patients, higher FoPA accounted for 30% of the startle potentiation by phobic priming, whereas general anxiety, depression, and disease severity were no significant predictors of startle modulation. These findings suggest that FoPA in patients with heart failure is associated with defensive responses on a physiological level that might be indicative of avoidance behavior, thereby contributing to low adherence to exercise regimen. Thus, FoPA presents a significant target for psychological interventions to foster physical activity in cardiac patients.

The effects of physical activity and sedentary behavior in the associations between cardiovascular diseases and depression: A four-way decomposition

BACKGROUND

Negative effects of cardiovascular diseases (CVDs) on depression have been reported, but the relative contribution of physical activity (PA) and sedentary behavior (SB) to such effects remains unclear. Our objective was to precisely quantify the effects modified or mediated by PA and SB using the recently developed four-way effect decomposition.

METHODS

Our analysis included 22,117 adults (aged≥20 years) participating in the 2007-2016 National Health and Nutrition Examination Survey (NHANES). Depression was assessed by the Patient Health Questionnaire-9. Moderate recreational activity (MRA), moderate work activity (MWA), and walk or bicycle for transportation, were measured by the Global Physical Activity Questionnaire (GPAQ). A four-way decomposition was applied with PA and SB as mediator to decompose the total effects of CVDs on depression into four components: controlled direct effect (CDE), pure indirect effect (PIE), reference interaction (INT_ref), and mediated interaction effect (INT_med).

RESULTS

There were statistically significant associations between CVDs, MRA, and depression, with the adjusted odds ratios (95% confidence intervals) of being 1.73 (1.42~2.30), 1.81 (1.42~2.30), respectively. With MRA as a mediator, there were interaction and mediation effects in the associations between CVDs and depression, and the proportions attributable of INT_ref, INT_med, and PIE were 94.08% (P<0.001), 3.92% (P = 0.007), and 1.68% (P = 0.006), respectively. Furthermore, the mediation effect was statistically significant in females rather than males.

CONCLUSIONS

MRA strongly modified and mediated the effects of CVDs on depression, especially in females. Our results suggested that sufficient MRA (at least 150 min per week) was considered as requirement for preventing depression in CVDs patients in females.

Decline in physical activity in the weeks preceding sustained ventricular arrhythmia in women

Background

Heightened risk of cardiac arrest following physical exertion has been reported. Among patients with an implantable defibrillator, an appropriate shock for sustained ventricular arrhythmia was preceded by a retrospective self-report of engaging in mild-to-moderate physical activity. Previous studies evaluating the relationship between activity and sudden cardiac arrest lacked an objective measure of physical activity and women were often underrepresented.

Objective

To determine the relationship between physical activity, recorded by accelerometer in a wearable cardioverter-defibrillator (WCD), and sustained ventricular arrhythmia among female patients.

Methods

A dataset of female adult patients prescribed a WCD for a diagnosis of myocardial infarction or dilated cardiomyopathy was compiled from a commercial database. Curve estimation, to include linear and nonlinear interpolation, was applied to physical activity as a function of time (days before arrhythmia).

Results

Among women who received an appropriate WCD shock for sustained ventricular arrhythmia (N = 120), a quadratic relationship between time and activity was present prior to shock. Physical activity increased starting at the beginning of the 30-day period up until day -16 (16 days before the ventricular arrhythmia) when activity begins to decline.

Conclusion

For patients who received treatment for sustained ventricular arrhythmia, a decline in physical activity was found during the 2 weeks preceding the arrhythmic event. Device monitoring for a sustained decline in physical activity may be useful to identify patients at near-term risk of a cardiac arrest.

Associated factors and impacts of sedentary behaviour in patients with heart failure: A longitudinal study

BACKGROUND

Sedentary behaviours may be related to factors such as self-efficacy, mood and social support. However, there is a paucity of longitudinal follow-up studies examining factors related to sedentary behaviour from physical-psychosocial perspectives in patients with heart failure.

AIMS

The purpose of this study was to explore the multidimensional associated factors and impacts of sedentary behaviour in heart failure patients.

METHODS

A longitudinal design was used. A convenience sample of 128 heart failure patients recruited from two large medical centres in northern Taiwan was obtained. Patients were interviewed with structured questionnaires to assess physical activity, symptom distress, exercise self-efficacy, anxiety and depression, social support, sleep quality and quality of life before discharge and at 3 and 6 months after discharge.

RESULTS

Heart failure patients reported low physical activity and tended to be sedentary. Sedentary behaviour was gradually reduced from hospitalization to 6 months after discharge. Sleep quality, quality of life, analgesic use, symptom distress and exercise self-efficacy were significant associated factors that explained 42.1-51% of the variance in sedentary behaviour. Patients with high sedentary behaviour had significantly greater depression and poorer sleep and quality of life than those with low sedentary behaviour at hospitalization and showed a significant improvement in depression at 3 and 6 months after discharge.

CONCLUSION

Sedentary behaviour is common in heart failure patients and has impacts on depression and quality of life. An appropriate physical activity programme focusing on disease self-management and enhancing self-efficacy is needed for heart failure patients to improve their sedentary behaviour and quality of life.

Self-reported and objectively measured physical activity in people with and without chronic heart failure: UK Biobank analysis

Objective

The impact of heart failure (HF) on perceived and objectively measured levels of physical activity (PA) can inform risk stratification and treatment recommendation. We aimed to compare self-reported and objectively measured PA levels in a large sample of participants with and without HF.

Methods

A validated PA questionnaire was used to estimate self-reported weekly PA among 1600 participants with HF and 387 580 participants without HF. Accelerometer data were studied in 596 participants with HF and 96 105 participants without HF for a period of 7 days. Using multivariable linear regression models, we compared the PA levels between participants with HF and without HF, focusing on both the average daily PA levels and the intensity of PAs throughout the day.

Results

PA levels were significantly lower in participants with HF using both self-report (excess metabolic equivalent of task hours per week of 26.5 (95% CI 24.7 to 28.4) vs 34.7 (95% CI 34.5 to 34.9), respectively (p<0.001)) and accelerometer measures (mean accelerations of 23.7 milligravity (95% CI 23.1 to 24.4) vs 28.1 milligravity (95% CI 28.0 to 28.1), respectively (p<0.001)). Findings were consistent across different PA intensities. Hour-by-hour comparisons showed that accelerometer-derived PA levels of patients with HF were reduced throughout the day.

Conclusion

Perceived and objectively recorded PA levels of patients with chronic HF are significantly lower than those of individuals without HF. This difference is continuous throughout the different hours of the day, with individuals with HF being on average 16% less active than individuals without HF. In patients with HF, increases in everyday activity may be a potential alternative to structured exercise programmes.

Self-efficacy Mediates the Relationship Between Motivation and Physical Activity in Patients With Heart Failure

BACKGROUND

Motivation is necessary in patients with heart failure (HF) who are attempting to become more physically active but may not be sufficient to initiate physical activity. Self-efficacy might explain the relationship between motivation and physical activity.

OBJECTIVE

The aim of this study was to examine the role of exercise self-efficacy in the relationship between exercise motivation and physical activity in patients with HF.

METHODS

A total of 100 stable patients with HF (88% in New York Heart Association class II/III; mean age, 67 ± 13 years; 62% men) were studied. Self-efficacy was measured with the Exercise Self-Efficacy Scale; motivation, with the Exercise Motivation Index; and physical activity, with a self-report questionnaire. Logistic regression analyses were made to examine the mediation effect of exercise self-efficacy on the relationship between exercise motivation and physical activity.

RESULTS

Forty-two percent of the 100 patients reported engaging in less than 60 minutes per week of physical activity. Motivation predicted physical activity (b = 0.58, P < .05), but after controlling for self-efficacy, the relationship between motivation and physical activity was no longer significant (b = 0.76, P = .06), indicating full mediation.

CONCLUSION

Motivation to be physically active is important but not sufficient. In addition to a high level of motivation to be physically active, it is important that patients with HF have a high degree of self-efficacy.

Accelerometer-Measured Daily Activity Levels and Related Factors in Patients With Heart Failure

BACKGROUND

Few studies report objective accelerometer-measured daily physical activity levels in patients with heart failure (HF).

OBJECTIVE

We examined baseline accelerometer-measured physical activity from the Heart Failure Exercise and Resistance Training Camp trial, a federally funded (R01-HL112979) 18-month intervention study to promote adherence to exercise in patients with HF. Factors associated with physical activity levels were also explored.

METHODS

Patients with diagnosed HF (stage C chronic HF confirmed by echocardiography and clinical evaluation) were recruited from 2 urban medical centers. Physical activity energy expenditure and the number of minutes of moderate or vigorous physical activity (MVPA) were obtained from 7 full days of measurement with the accelerometer (Actigraph Model GT3X, Pensacola, Florida) for 182 subjects who met minimum valid wear time parameters. Additional measures of health-related factors were included to explore the association with physical activity levels.

RESULTS

Subjects had 10.2 ± 10.5 minutes of MVPA per day. Total physical activity energy expenditure was 304 ± 173 kcal on average per day. There were 23 individuals (12.6%) who met the recommended goal of 150 minutes of MVPA per week. Men, whites, New York Heart Association class II, and subjects with better physical function had significantly higher levels of activity.

CONCLUSIONS

Consistent with previous research, patients with HF are not meeting recommended guidelines for 150 minutes of MVPA per week.

Framework analysis: A worked example from a midwifery research

OBJECTIVE

Framework analysis is a pragmatic approach for real-world investigations and has been commonly used in health care research. Although the theoretical part of framework analysis has been well documented, there is limited literature describing its practical use. The objective of this paper is to demonstrate systematic and explicit guidance in using framework analysis by giving an example of a study exploring women's experience of postnatal depression.

METHOD

Data presented in this paper comes from semi-structured interviews of 33 women (from three different cultural backgrounds) attending for a child or postnatal care in six purposively selected maternal and child health (MCH) clinics in Kuala Lumpur.

RESULTS

Data were analyzed using framework analysis, which consists of three interrelated stages. In the first stage (data management), a careful selection of the data (transcripts) to be reviewed was made. The initial categories were developed based on the selected transcripts, and the initial themes were decided (known as a thematic framework). In the second stage (descriptive accounts), the thematic framework was investigated to identify any linkage and similarity between one category to another. The third stage of the analysis (explanatory accounts) involved checking exactly how the level of matching between the phenomena was distributed across the whole set of data. Using framework analysis, four themes were identified to explain the women's experience of postnatal depression namely the changes, causal explanations, dealing with postnatal depression, and perceived impacts.

CONCLUSIONS

The details of each stage of the analysis were explained to guide researchers through essential steps in undertaking framework analysis. Health care researchers may find a worked example addressed in this paper as useful when analyzing qualitative data.

Intensification to injectable therapy in type 2 diabetes: mixed methods study (protocol)

BACKGROUND

In the UK, type 2 diabetes mellitus (T2D) is largely managed in primary care. Delay in the intensification to injectable therapy, a form of clinical inertia, is associated with worse glycaemic control. UK general practice is highly computerised, with care being recorded on computerised medical record systems; this allows for quantitative analysis of clinical care but not of the underpinning decision-making process. The aim of this study is to investigate perceptions of patients and clinicians in primary care on the initiation of injectable therapies in T2D, and the context within which those decisions are made.

METHODS

This is a mixed methods study, taking a "realist evaluation" approach. The qualitative components comprise focus groups, interviews, and video recordings of simulated surgeries; the quantitative analysis: an overview of participating practices, elements of the video recording, and an online survey. We will recruit primary care clinicians (general practitioners and nurses) and patients from a representative sample of practices within the Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) network. Participants will be patients with T2D, and primary care clinicians. Focus groups and semi-structured interviews will be recorded, transcribed verbatim and analysed using Framework Analysis. The simulated surgeries will include cases that might be escalated to injectable therapy. The consultation will be reviewed using the Calgary-Cambridge model to assess communication and determination of adherence to national prescribing guidelines. We will conduct multi-channel video recording including screen capture, clinician and patient facial expressions, wide angle view of the consultation, and the computerised medical record screen. This allows annotation and qualitative analysis of the video recordings, and statistical analyses for the quantitative data. We will also conduct an online survey of primary care clinicians' attitudes to, and perceptions of, initiation of injectable therapies, which will be analysed using summary statistics.

DISCUSSION

Results aim to provide a detailed insight into the dynamic two-way decision-making process underpinning use of injectable therapy for T2D. The study will provide insights into clinical practice and enable the development of training, interventions and guidelines that may facilitate, where appropriate, the intensification to injectable therapy.

Validity of the Low-Impact Dance for exercise-based cardiac rehabilitation program

PURPOSE

The aim of this study was to evaluate the oxygen uptake in patients with cardiovascular disease during the low-impact dance program and to compare the findings with the values at peak oxygen uptake (VO2) and aerobic threshold (AT).

METHODS

The study included 19 patients with cardiovascular disease [age, 68.3±8.7 years; left-ventricular ejection fraction, 60.3%±8.7%; peak VO2, 6.6±1.1 metabolic equivalents (METs)] who were receiving optimal medical treatment. Their heart rate and VO2 were monitored during cardiopulmonary exercise testing (CPET) and during the low impact dance. The dance involved low-impact dynamic sequences. The patients completed two patterns of low-impact dance, and metabolic gas exchange measurements were obtained using a portable ergospirometry carried in a backpack during the dance sessions.

RESULTS

The mean values of VO2 (4.0±0.2 METs and 3.9±0.3 METs) and those of heart rate (105.2±2.9 bpm and 96.8±2.6 bpm) during the dance program were not significantly differ from the AT value (4.5±0.2 METs) obtained in CPET. The median (and interquartile range) RPE reported after the dance exercise trials was 11 (9-13). No signs of overexertion were observed in any of the patients during either dance exercise trial.

CONCLUSIONS

The results suggest that it is reasonable to consider the low-impact dance program as an aerobic exercise program in cardiac rehabilitation. Our findings have important implications for exercise training programs in the cardiac rehabilitation setting and for future studies.

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.

A qualitative meta-summary using Sandelowski and Barroso's method for integrating qualitative research to explore barriers and facilitators to self-care in heart failure patients

BACKGROUND

Individual qualitative studies provide varied reasons for why heart failure patients do not engage in self-care, yet articles that aggregated primary studies on the subject have methodological weaknesses that justified the execution of a qualitative meta-summary.

AIM

The aim of this study is to integrate the findings of qualitative studies pertaining to barriers and facilitators to self-care using meta-summary techniques.

METHODS

Qualitative meta-summary techniques by Sandelowski and Barroso were used to combine the findings of qualitative studies. Meta-summary techniques include: (1) extraction of relevant statements of findings from each report; (2) reduction of these statements into abstracted findings and (3) calculation of effect sizes. Databases were searched systematically for qualitative studies published between January 2010 and July 2015. Out of 2264 papers identified, 31 reports based on the accounts of 814 patients were included in the meta-summary.

RESULTS

A total of 37 statements of findings provided a comprehensive inventory of findings across all reports. Out of these statements of findings, 21 were classified as barriers, 13 as facilitators and three were classed as both barriers and facilitators. The main themes relating to barriers and facilitators to self-care were: beliefs, benefits of self-care, comorbidities, financial constraints, symptom recognition, ethnic background, inconsistent self-care, insufficient information, positive and negative emotions, organizational context, past experiences, physical environment, self-initiative, self-care adverse effects, social context and personal preferences.

CONCLUSION

Based on the meta-findings identified in this study, future intervention development could address these barriers and facilitators in order to further enhance self-care abilities in heart failure patients.

The Role of Web-Based Health Information in Help-Seeking Behavior Prior to a Diagnosis of Lung Cancer: A Mixed-Methods Study

BACKGROUND

Delays to diagnosis in lung cancer can lead to reduced chance of survival, and patients often wait for several months before presenting symptoms. The time between first symptom recognition until diagnosis has been theorized into three intervals: symptom appraisal, help-seeking, and diagnostic interval (here: "pathway to diagnosis"). Interventions are needed to reduce delays to diagnosis in lung cancer. The Web has become an important lay health information source and could potentially play a role in this pathway to diagnosis.

OBJECTIVE

Our overall aim was to gain a preliminary insight into whether Web-based information plays a role in the pathway to diagnosis in lung cancer in order to assess whether it may be possible to leverage this information source to reduce delays to diagnosis.

METHODS

Patients diagnosed with lung cancer in the 6 months before study entry completed a survey about whether (and how, if yes) they had used the Web to appraise their condition prior to diagnosis. Based on survey responses, we purposively sampled patients and their next-of-kin for semistructured interviews (24 interviews; 33 participants). Interview data were analyzed qualitatively using Framework Analysis in the context of the pathway to diagnosis model.

RESULTS

A total of 113 patients completed the survey (age: mean 67.0, SD 8.8 years). In all, 20.4% (23/113) reported they or next-of-kin had researched their condition online before the diagnosis. The majority of searches (20/23, 87.0%) were conducted by or with the help of next-of-kin. Interview results suggest that patients and next-of-kin perceived an impact of the information found online on all three intervals in the time to diagnosis. In the appraisal interval, participants used online information to evaluate symptoms and possible causes. In the help-seeking interval, the Web was used to inform the decision of whether to present to health services. In the diagnostic interval, it was used to evaluate health care professionals' advice, to support requests for further investigation of symptoms, and to understand medical jargon. Within this interval, we identified two distinct subintervals (before/after relevant diagnostic tests were initiated), in which the Web reportedly played different roles.

CONCLUSIONS

Because only 20.4% of the sample reported prediagnosis Web searches, it seems the role of the Web before diagnosis of lung cancer is at present still limited, but this proportion is likely to increase in the future, when barriers such as unfamiliarity with technology and unwillingness to be informed about one's own health are likely to decrease. Participants' perceptions suggest that the Web can have an impact on all three intervals in the pathway to diagnosis. Thus, the Web may hold the potential to reduce delays in the diagnostic process, and this should be explored in future research and interventions. Our results also suggest a division of the diagnostic interval into two subintervals may be useful.

"We are all there for the same purpose": Support for an integrated community exercise program for older adults with HF and COPD

BACKGROUND

Despite well-established improvements following rehabilitation, functional gains often diminish following discharge.

OBJECTIVE

To explore the attitudes of older adults with HF and COPD, who have completed rehabilitation, toward community-based exercise maintenance.

METHODS

Semi-structured interviews were conducted with 11 individuals with HF or COPD.

RESULTS

Deductive thematic analysis uncovered three themes: 1) transitioning to community exercise is challenging, highlighting participants' struggle with unstructured maintenance and a lack of appropriate programs; 2) a structured, group-based program tailored to functional ability facilitates adherence, describing participants views on the importance of routine, and accountability; and 3) "We are all there for the same purpose" - participant support for integrated exercise, including the benefit of multiple perspectives and sustainability.

CONCLUSIONS

A motivating program leader and access to appropriate facilities are key features to support adherence to prescribed activity. Tailored programs can be delivered consecutively to older adults with HF and COPD.

Self-Care Behaviors of African Americans Living with Heart Failure

African Americans have a higher risk of developing heart failure (HF) than persons from other ethnic groups. Once diagnosed, they have lower rates of HF self-care and poorer health outcomes. Promoting engagement in HF self-care is amenable to change and represents an important way to improve the health of African Americans with HF. This study used a community-based participatory action research methodology called photovoice to explore the practice of HF self-care among low-income, urban, community dwelling African Americans. Using the photovoice methodology, themes emerged regarding self-care management and self-care maintenance.

Beliefs, Barriers and Facilitators to Physical Activity in Bariatric Surgery Candidates

BACKGROUND

Bariatric surgery candidates engage in less physical activity (PA) and spend longer periods in sedentary behaviour (SB) when compared to the general adult population. The aim of this study was to explore the beliefs about PA and perceived barriers and facilitators to PA in obese adults scheduled for bariatric surgery.

METHODS

Nineteen obese adults (15 females), with a mean (SD) age of 41.6 (12.1) years, weight of 119.2 (20.5) kg and body mass index of 41.6 (6.7) kg/m(2) participated in a one-on-one in-depth qualitative interview before undergoing bariatric surgery. Data were analysed using inductive thematic analysis.

RESULTS

Most participants believed that engaging in regular PA confers important health benefits, however reported insufficient PA levels to obtain those benefits. The perceived barriers to PA reported by participants were both obesity related (e.g. bodily pain, physical limitation and self-presentational concerns) and non-obesity related (e.g. lack of motivation, environment and restricted resources). All participants stated weight loss to be the main perceived facilitator to PA, together with social factors, better time management and access to financial resources.

CONCLUSIONS

In bariatric surgery candidates, many of the perceived barriers and facilitators to PA are not obesity related and are therefore unlikely to change as a result of bariatric surgery. This may explain why earlier research shows little change in PA or SB following surgery. It is likely that an approach that aims to address the barriers and facilitators identified in this study is needed to change the inactive lifestyle adopted in this population.

Perceived Barriers to and Facilitators of Physical Activity in Recipients of Solid Organ Transplantation, a Qualitative Study

Background

Sufficient physical activity is important for solid organ transplant recipients (heart, lung, liver, kidney). However, recipients do not meet the recommended amount or required type of physical activity. The perceived barriers to and facilitators of physical activity in this population are largely unknown.

Methods

Semi-structured in depth interviews were conducted with solid organ transplant recipients in order to explore experienced barriers and facilitators. Qualitative methodology with thematic line-by-line analysis was used for analysis, and derived themes were classified into personal and environmental factors.

Results

The most important indicated barriers were physical limitations, insufficient energy level, fear, and comorbidities. The most frequently mentioned facilitators included motivation, coping, consequences of (in)activity, routine/habit, goals/goal priority, and responsibility for the transplanted organ. Neutral factors acting as a barrier or facilitator were self-efficacy and expertise of personnel. A comparison of barriers and facilitators between transplant recipient groups yielded no overt differences.

Conclusion

Several personal and environmental factors were indicated that should be considered in intervention development to increase physical activity behavior in solid organ transplant recipients.

Team-based Care for Cardiac Rehabilitation and Exercise Training in Heart Failure

The estimated cost of treating patients with HF in the United States is expected to more than double by 2030.65 This forecast of the impact of HF in the United States should serve as a call to action. Despite well-documented benefits, participation in exercise training and CR programs by patients with HF remains low. In this article, standards and guidelines for exercise and CR in HF were reviewed. Although traditional CR had core components, it lacked care management specific for HF. Chronic stable HF patients can safely exercise; however, there are many unique needs that are not currently addressed at the patient, system, and provider levels. As we face economic and political forces that are expected to require major change to the health care delivery system, it becomes even more important to capitalize on the advantages that come with team-based care. CR has always served as a model of team-based care; however, the model must now include professionals with HF expertise to guide patients in safe exercise and self-management strategies appropriate for this chronically ill population.

The anticipated and the lived experience of home and in-centre haemodialysis: Is there a disconnect?

This qualitative study aimed to explore home haemodialysis and in-centre haemodialysis patients’ experience, to illuminate barriers and facilitators in the uptake and maintenance of home haemodialysis. Thirty-two semi-structured interviews with patients receiving home haemodialysis or in-centre haemodialysis were analysed using framework analysis. Four themes emerged: ‘perceptions of self’; ‘impact of haemodialysis on family’; ‘perceived advantages and disadvantages of home haemodialysis and in-centre haemodialysis’ and ‘practical issues and negotiating haemodialysis’. The lived experience of home haemodialysis was in contrast to the lived experience of in-centre haemodialysis and to the anticipated experience of home haemodialysis, highlighting patient factors that contributed to under-usage of home haemodialysis.

A Home-Based Diaphragmatic Breathing Retraining in Rural Patients With Heart Failure

Dyspnea limits physical activity and functional status in heart failure patients. This feasibility study examined effects of a diaphragmatic breathing retraining (DBR) intervention delivered over 8 weeks with follow-up at 5 months. The intervention group (n = 18) was trained at baseline and received four telephone calls. An attention control group (n = 18) received four telephone calls with general health information. Results from linear mixed model analysis with effect sizes (η(2)) showed dyspnea improved in both groups, with little difference between groups. Compared with attention alone, the intervention increased physical activity (calories expended; η(2) = .015) and functional status (η(2) = .013) across the 5-month follow-up and increased activity counts at 8 weeks (η(2) = .070). This intervention was feasible and demonstrated promising effects on activity and function but not by reducing dyspnea. Patients may have increased physical activity because of instructions to use DBR during activities of daily living. Further exploration of the intervention's underlying physiological effect is needed.

Self-Care Motivation Among Patients With Heart Failure: A Qualitative Study Based on Orem’s Theory

Background and Purpose: Initiating and adhering to self-care activities necessitate self-care motivation. This study was undertaken in Iran to explore self-care motivation among patients with heart failure (HF). Methods: This qualitative study was done in 2014 and 2015. Study participants were patients with HF and their family members who were purposively selected from Shaheed Rajaei Cardiovascular, Medical and Research Center, Tehran, Iran. The study data were collected from December 2014 to May 2015 by doing in-depth semistructured face-to-face interviews and were analyzed via the directed content analysis approach. Results: Eleven primary codes were generated which reflected motivations for self-care among patients with HF in the Iranian sociocultural context. To enhance the clarity of the findings, these primarily codes were summarized and grouped into 7 subcategories including fear of death and love of life, returning to previous physical health status and preventing or alleviating symptoms, understanding the value of self-care behaviors and trusting them, having the desire for remaining independent, relying on God, reassuring and supporting family members, and preventing family members from feeling irritation. Implications for Practice: The findings of this study indicate that patients with HF have different motivations for doing self-care activities. Fear of death, love of life, wish to return to previous health status, and prevention or alleviation of HF symptoms were the participants’ strongest motivations for self-care. Understanding the motivations for self-care among patients with HF, based a holistic approach and evidence-based practice, can help nurses and physicians develop motivational programs for promoting self-care behaviors.

Development of Motivate4Change Using the Intervention Mapping Protocol: An Interactive Technology Physical Activity and Medication Adherence Promotion Program for Hospitalized Heart Failure Patients

Background

It is important that heart failure (HF) patients adhere to their medication regimen and engage in physical activity. Evidence shows that adherence to these HF self-management behaviors can be improved with appropriate interventions.

Objective

To further promote medication adherence and physical activity among HF patients, we developed an intervention for hospitalized HF patients.

Methods

The intervention mapping protocol was applied in the development of the intervention. This entailed performing a needs assessment, defining change objectives, selecting determinants and strategies, and developing the materials.

Results

The resulting intervention, Motivate4Change, makes use of interactive technology and provides HF patients with personalized feedback and advice. Specific change objectives were defined. The relevant behavioral determinants for the physical activity program were practical knowledge on physical activity performance and self-efficacy for, and perceived benefits of, physical activity. For medication-taking, the selected determinants were practical knowledge on medication-taking, perceived barriers to medication-taking, beliefs about the necessity and harm regarding the medication prescribed, and beliefs about overprescribing and harm of medication in general. The change objectives and behavior change determinants were translated in feedback and advice strategies in an interactive technology program that included tailored feedback and advice, and role models in videos in which the behaviors and overcoming barriers were demonstrated. Relevant stakeholders were involved in the interventions development process. The intervention was pretested among HF patients and adjustments were made accordingly.

Conclusions

The interactive technology physical activity and medication adherence promotion program for hospitalized HF patients was systematically developed using the intervention mapping protocol and was based on the available theory and evidence regarding HF self-management behavior change. The intervention’s efficacy is yet to be determined in evaluation research.

Self-concepts of exercise in frail older adults with heart failure: a literature review

The co-occurrence of frailty and heart failure (HF) in older adults (65 years or older) can adversely affect the ability to engage in self-care management behaviors, which may alter self-concepts and decrease quality of life. Little is known about how frailty and HF influence older adults' self-concepts or how these self-concepts affect exercise behaviors. Therefore, the aims of this literature review were to identify the self-concepts of older frail adults with HF and to identify how these self-concepts affect their exercise behaviors. Guided by the schema model of self-concept, publications before April 2013 that examined the impact of the self-concepts of older adults with HF and/or frailty on exercise behavior were reviewed. As a result, 6 articles were included. Three of the 6 articles focused on frailty, and 3 of the 6 articles focused on HF. However, no study was found that specifically examined the self-concepts of frail older adults with HF. The self-concepts of older adults with HF and/or frailty are multifaceted and include both cognitive resources (facilitating exercise) and cognitive liabilities (hindering exercise). Studies are needed to determine how the co-occurrence of frailty and HF impact self-concepts and exercise behaviors in older adults.

Factors influencing ceftriaxone use in community-acquired pneumonia: Emergency doctors' perspectives

OBJECTIVE

To explore the perceptions of ED doctors regarding the use of ceftriaxone in patients with community-acquired pneumonia (CAP).

METHODS

Face-to-face interviews were conducted with ED doctors in an Australian tertiary public hospital. A semi-structured interview method was used for collecting data and a framework analysis approach utilised to identify emerging themes regarding the influences on ED prescribers when using ceftriaxone for CAP.

RESULTS

Eight interviews were performed (two consultants, four registrars and two residents). Five main themes emerged as influencing decisions regarding the selection of ceftriaxone for patients with CAP: (i) clinical intuition versus structured evaluation of severity; (ii) clinical uncertainty; (iii) prior experience; (iv) source of guidance; and (v) prescribing etiquette.

CONCLUSION

As most cases of CAP are initially diagnosed and treated empirically in the ED, any interventions that aim to decrease inappropriate use of ceftriaxone for CAP should address the factors identified here that influence ED doctors' prescribing decisions.
