RESUMEN
BACKGROUND: Heart failure (HF) is a major public health problem that places a significant disease burden on society. Self-care is important in the management of HF because it averts disease progression and reduces the number of hospitalizations. Effective nursing interventions promote HF self-care. OBJECTIVE: This study aims to explore participants' perspectives on a nurse-led, home-based heart failure self-management program (HOM-HEMP) in a randomized controlled trial conducted in Singapore to gain insight into the effectiveness of the study intervention. METHODS: A descriptive, qualitative approach was used. English- or Chinese-speaking participants from the intervention arms were recruited through a purposive sampling method from January 2019 to July 2019. Individual, face-to-face, semistructured interviews were conducted with 11 participants. All interviews were audio recorded and transcribed verbatim, with the participant identifiers omitted to ensure confidentiality. The thematic analysis approach was used to identify, analyze, and report patterns (themes) within the data. RESULTS: A total of six themes emerged from the process evaluation interviews and were categorized according to the Donabedian structure-process-outcome framework as intervention structure, intervention process, and intervention outcome. These six themes were manageability of the intervention, areas for improvement, benefits of visiting, personal accountability in self-care, empowered with knowledge and skills in self-care after the intervention, and increased self-efficacy in cardiac care. CONCLUSIONS: The findings of the process evaluation provided additional information on participants' perceptions and experiences with the HOM-HEMP intervention. Although a home visit may be perceived as resource intensive, it remains to be the preferred way of engagement for most patients. Nurses play an important role in promoting HF self-care. The process of interaction with the patient can be an important process for empowering self-care behavior changes.

BACKGROUND: A person's self-efficacy plays a critical role during the chronic management process of a health condition. Assessment of self-efficacy for patients with heart diseases is essential for healthcare professionals to provide tailored interventions to help patient to manage the disease. OBJECTIVE: To translate and test the psychometric properties of the Chinese version of Cardiac Self-efficacy Scale (C-CSES) as a disease-specific instrument for patients with coronary heart disease (CHD) in mainland China. METHODS: The original English version of the CSES was translated into Chinese using a forward-backward translation approach. A convenience sample consisting of 224 Chinese patients with CHD were recruited from a university-affiliated hospital in Shiyan, China. The C-CSES and the General Self-efficacy Scale (GSES) were used in this study. The factor structure, convergent and discriminative validities, and internal consistency of the C-CSES were evaluated. RESULTS: The confirmatory factor analysis (CFA) supported a three-factor high-order structure of the C-CSES with model fit indexes (RMSEA = 0.084, CFI = 0.954, NNFI = 0.927, IFI = 0.954 and χ 2 /df = 2.572). The C-CSES has good internal consistency with a Cronbach's alpha of 0.926. The convergent validity of the C-CSES was established with significantly moderate correlations between the C-CSES and the Chinese version of the GSES (p < 0.001). The C-CSES has also shown good discriminative validity with significant differences of cardiac self-efficacy being found between patients with and without comorbidities of hypertension, diabetes, or heart failure. CONCLUSION: The empirical data supported that the C-CSES is a valid and reliable disease-specific instrument for assessing the self-efficacy of Chinese patients with CHD.

PURPOSE: The Patient Activation Measure (PAM-13) measures patients' knowledge, skill, and confidence in chronic condition self-management. The purpose of this study was to assess the validity of PAM-13 (English version) among English-speaking adults with cardiac conditions in Singapore. METHODS: A cross-sectional study was conducted in a convenient sample of 270 heart clinic patients. Using the unitary concept of validity, evidence of (1) internal structure via data quality, unidimensionality, differential item functioning, and internal consistency, (2) response process through item difficulty and item fit using Rasch modeling, and (3) relationship to other variables via correlations with depression and self-efficacy were examined. RESULTS: The item response was high with only one missing answer. All items had a small floor effect, but nine out of 13 items had a ceiling effect larger than 15 %. Cronbach's α was 0.86, and average inter-item correlations was 0.324. Results suggested unidimensionality; however, differences in item difficulty ranking were found. A low, negative correlation was found with depression, while a moderate, positive correlation was found with self-efficacy. CONCLUSION: Evidence in all three areas of validity were mixed. Caution should be exercised when using categorical activation "level" to inform clinical decisions.

AIM: To develop and examine the effectiveness of an advanced practice nurse-led telehealth rehabilitative programme as a transitional nursing therapeutic on readmission rates and health-related outcomes among patients with acute myocardial infarction postdischarge. BACKGROUND: Patients suffering from acute myocardial infarction are experiencing an increasing trend of frequent readmissions. This implicates both the effectiveness of healthcare services and patient's quality of life. Advanced Practice Nurse-led telehealth rehabilitative programme has yet to be explored as a strategy to minimize preventable readmissions and improve patient's self-efficacy so as to enhance quality of life after a heart attack. DESIGN: Randomized controlled trial with repeated measures. METHODOLOGY: A consecutive sampling of 172 patients with acute myocardial infarction will be recruited from a tertiary acute hospital in Singapore. Participants will be randomized into two groups. The experimental group (ALTRA) will receive Advanced Practice Nurse-led telehealth rehabilitative programme on discharge. The control group will receive only standard follow-up care. The outcome measures include readmissions, cardiac self-efficacy, cardiovascular risk factors, quality of life, anxiety and depression. The data will be collected at the baseline, 1 and 6 month postdischarge. A postprogramme evaluation will be conducted among the participants to assess its acceptability, strengths and weakness. DISCUSSION: ALTRA aims to engage and support patients with acute myocardial infarction by increasing self-care management through education and telehealth contacts with Advanced Practices Nurses. This provides a smoother transition of illness to health and ultimately, reduces preventable costly readmissions. TRIAL REGISTRATION: The study has been registered with clinicaltrials.gov. The trial registration number is NCT02483494.

BACKGROUND: Chronic heart failure (CHF) remains as a debilitating disease that has high mortality among adults worldwide. CHF negatively impacts an individual's health-related quality of life (HRQoL), but only few studies have investigated such an impact in the Asian population. AIMS: This study aims to investigate the HRQoL of outpatients with CHF and identify its predictors among this group of patients in Singapore. METHODS: This was a cross-sectional, descriptive correlational study. A convenience sampling of 121 outpatients with CHF was recruited from a public hospital over 5 months. The Minnesota Living with Heart Failure Questionnaire (MLHFQ), Short Form-Cardiac Depression Scale, Cardiac Self-Efficacy Scale, and Medical Outcomes Study Social Support Survey were used to measure the study variables. RESULTS: There were significant differences in the HRQoL as assessed using the MLHFQ between gender, educational level, and primary caregiver status (p<0.05). Self-efficacy (ß=0.637, p<0.001) and depression (ß=-0.220, p<0.001) were found to be the predictors of the HRQoL in outpatients with CHF, accounting for 67.9% of variance. CONCLUSION: The results of the study indicated that lower levels of self-efficacy and depression predicted poor HRQoL. Nursing care should focus on detecting depressive symptoms in patients with CHF. A program facilitating better self-care is important in CHF management.

AIM: To report a study protocol of a randomized controlled trial examining if a symptom self-management programme helps patients with acute myocardial infarction self-manage their physical and psychological symptoms. BACKGROUND: In addition to physical conditions, people with acute myocardial infarction often experience psychological symptoms. However, there is limited empirical evidence on how to help individuals self-manage these psychological symptoms. DESIGN: A single-blinded, randomized controlled trial is proposed. METHODS: A convenience sample of 90 will be recruited. Eligible participants will be adult patients with acute myocardial infarction hospitalized at a tertiary hospital in Singapore. Participants will be randomly assigned to one of the three treatment groups: Intervention 1 and standard care (n = 30), Intervention 2 and standard care (n = 30) and standard care alone (n = 30). Data will be collected by self-reported questionnaires, physiological measures and open-ended questions. Quantitative data will be analysed by descriptive statistics, t-test, analysis of covariance and repeated measures analysis of variance. Open-ended questions will be analysed by content analysis. DISCUSSION: This study will identify a potentially efficacious symptom self-management programme for patients with acute myocardial infarction. If the efficacy of the programme is demonstrated, the programme can be integrated into hospital services to improve patient care. A new teaching method (virtual reality-based teaching) and new teaching materials (virtual reality videos and relaxation videos) derived from this study can be offered to patients. Future research with larger samples and multi-centre recruitment can be undertaken to further test the efficacy of the interventions.

BACKGROUND: Although important, heart failure self-care remains a challenge for many patients. This study aimed to evaluate the effect of a nurse-led, home-based self-management psychosocial education intervention (HOM-HEMP). The primary outcome was patient's HF self-care in terms of maintenance, management and confidence. The secondary outcomes were cardiac self-efficacy, psychological wellbeing in terms of perceived social support, health related quality of life and levels of anxiety and depression. The clinical outcomes included New York Heart Association (NYHA) functional class and numbers of unplanned health service visits due to cardiac-related reasons. DESIGN: A three-arm stratified randomized controlled trial was conducted (Clinical trial registration number: NCT03108235). METHODS: A total of 213 participants admitted for heart failure were recruited from the inpatient wards of a tertiary public hospital in Singapore. They were randomly allocated to the control group, the experimental group A or the experimental group B. All participants received the usual care provided by the hospital. Participants in experimental groups A and B received the HOM-HEMP intervention, and those in experimental group B received an additional supplemental smartphone application. Data were collected at baseline, 6 weeks, 3 months and 6 months from baseline. RESULTS: Compared to the control groups, participants in either of the experimental group had significantly higher levels of heart failure self-care maintenance (F = 4.222, p = 0.001), self-care confidence (F = 5.796, p < 0.001) and self-care management (p < 0.05) at 6-week, 3-month and 6-month follow-ups. In addition, both experimental groups had significantly higher levels of cardiac self-efficacy, better health related quality of life and lower depression levels than the control group after the study intervention. A higher proportion of participants in both experimental groups had a better New York Heart Association functional class at 6-week and 3-month follow-ups. Participants in the experimental group B also had significantly fewer cardiac-related unplanned hospital admissions and emergency room visits than the control group at 6-month follow-up. Results on perceived social support were not significant. The study outcomes in experimental group A and B were not significantly different at any of the post intervention follow-up. CONCLUSION: The findings suggested that HOM-HEMP is an effective intervention for patients with heart failure in Singapore.

BACKGROUND: Chronic heart failure (CHF) is one of the most common causes of hospital admissions and readmissions. Managing CHF requires a comprehensive treatment plan that consists of medication treatment and behavioural change. However, patients often feel unprepared for their self-management role in the community, especially during the period of transition after discharge from hospital. Therefore, an effective intervention to promote CHF self-management is needed. AIMS: This paper describes the development and pilot testing of a multicomponent nursing intervention (i.e. the HOM-HEMP) for a randomised controlled trial to assess its effectiveness in improving self-care behaviour among CHF patients in Singapore. A description of the study intervention is also delineated in detail. METHODS: The HOM-HEMP was developed based on the UK Medical Research Council framework for developing and evaluating complex interventions. After the development of the study intervention, a single group pre- and post-repeated measure pilot test was conducted to evaluate the study intervention package for its acceptability and the feasibility of the data collection procedure. Ten participants were recruited through consecutive sampling. All of the participants received the full intervention package with the supplementary mobile application. The data were collected at baseline and immediately after the study intervention (i.e. 6 weeks from baseline). The outcome measures included the Self-Care Heart Failure Index, Cardiac Self-Efficacy Scale, Minnesota Living with Heart Failure Questionnaire, Hospital Anxiety and Depression Scale and Short Form of the Social Support Questionnaire. RESULTS: The results from the pilot testing showed that the programme was feasible and potentially effective in improving patient's self-care management, psychological outcomes and health-related quality of life. CONCLUSION: A self-management psychosocial education approach is the preferred choice for many patients with chronic diseases. The effectiveness of the HOM-HEMP will next be tested in a full scale randomised control trial.

BACKGROUND: Despite the increasing use of implantable cardioverter defibrillators (ICDs) as a preventive approach for high-risk patients with arrhythmias, little is known about the perceptions of ICD recipients regarding these devices and their impact on quality of life. OBJECTIVES: To explore perceptions towards quality of life, coping strategies, and learning needs of patients living with ICDs in Singapore. METHODS: 16 participants (age ranges 52 to 84 years old) were purposively recruited and interviewed individually for this exploratory qualitative study. Data collected was analyzed using thematic analysis. RESULTS: Seven themes emerged: experiencing ICD shocks, ambivalent "love-hate" relationship with ICD, receiving support from healthcare professionals and social networks, attaining acceptance and returning to normalcy, physical coping, emotional coping, and readiness and need for enhanced patient education. CONCLUSIONS: With an insight to the perceptions of ICD recipients in Singapore, future practice can focus on addressing their concerns and improve post-implantation quality of life.

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia and has debilitating effects on patients' health-related quality of life (HRQoL) and psychological statuses. AIM: To investigate the HRQoL, psychological distress, and symptom burden, and to identify the significant influencing factors of HRQoL among outpatients with AF in Singapore. METHODS: We conducted a cross-sectional descriptive correlational study of a sample of 116 outpatients with AF. Data were collected using 12-item Short Form Health Survey, Atrial Fibrillation Effect on Quality of Life scale, Patient Health Questionnaire-9 (PHQ-9), and University of Toronto Atrial Fibrillation Symptom Severity (AFSS) scale. RESULTS: Symptom burden and psychological distress significantly influenced the AF-specific HRQoL while symptom burden, unemployment and comorbidity of heart failure were significantly associated with poorer general physical health. Psychological distress was the only significant factor influencing the mental health. CONCLUSION: Optimal symptom management is crucial for better HRQoL in patients with atrial fibrillation.

PURPOSE: Validation studies of the PAM-13 have found differences in scale performance, suggesting that health beliefs embedded in different cultures and/or self-management needs of different client groups influence how people respond to the items. The purpose of this study was to examine how adults with cardiac conditions in Singapore interpreted and responded to the PAM-13, to investigate possible reasons for differences in responses and to propose solutions to overcome them. METHODS: We conducted retrospective cognitive interviews with 13 participants in an out-patient heart center. Interviews were transcribed and analyzed based on the framework approach to qualitative analysis. The four stages from Tourangeau's cognitive model were used as a framework to index the data from each item. RESULTS: There was variation in comprehension of questions leading to variation in responses. Comprehension issues were due to terms perceived by participants to be vague and the use of English terms uncommon in Singapore. Cultural influences impacted decision processes and problems with response processes of the self-rating Likert scale surfaced. CONCLUSIONS: This study reinforces the need to culturally adapt the tool, even when language translation is not necessary. Providing Likert scales with a larger number of may widen the relevance of PAM-13 in Singapore. Implications for rehabilitation Need to culturally adapt assessment tool, even when language translation is not necessary. Consider using Likert scales with a larger number of categories when using in Asian countries such as Singapore. Caution must be taken when using PAM-13 levels to decide interventions for each individual.

AIM: To examine the effectiveness of a four-week home-based self-management rehabilitation programme on health-related quality of life, anxiety and depression levels, cardiac risks and unplanned visits to the health services among community-dwelling patients with myocardial infarction. METHODS: A randomised controlled trial with repeated measurements was used. A convenience sample of 128 patients with myocardial infarction was recruited from outpatient cardiology clinics at a tertiary hospital in Singapore. Participants were randomly assigned to the intervention group or control group. The outcomes were measured using Short Form 12-item Health Survey Version 2, Myocardial Infarction Dimensional Assessment Scale, and Hospital Anxiety and Depression Scale. The cardiac physiological risk parameters and number of unplanned health service use were also assessed. Data were collected at baseline, and at four weeks and 16 weeks from the baseline. RESULTS: Over the 16 weeks, the two groups reported significant differences in physical activity (F = 4.23, p = 0.02), dependency (F = 5.16, p = 0.01), concerns over medication (F = 3.47, p = 0.04) on MIDAS, anxiety level (F = 3.41, p = 0.04) and body mass index (F = 3.12, p = 0.04). A significant difference was also found in unplanned cardiac-related emergency room visits (χ(2) = 6.64, p = 0.036) and medical consultation (χ(2) = 9.67, p = 0.046) at the 16-week study point. CONCLUSION: The study may provide a useful tool to help health care professionals to meet the cardiac rehabilitative care needs of community-dwelling patients with myocardial infarction in Singapore.
