Trajectories of Self-Care Confidence and Maintenance in Adults with Heart Failure: A Latent Class Growth Analysis

Structural Relationships Between Cognitive Function, Depressive Symptoms, Self-Care Confidence, and Maintenance in Patients With Heart Failure

Introduction

In order to promote self-care maintenance behavior in patients with heart failure (HF), it is necessary to identify the direct and indirect effects of major latent variables.

Objective

This study aimed to identify structural relationships between different domains of cognitive function, depression and self-care confidence, and self-care maintenance.

Methods

This descriptive study involved a secondary analysis using data of 201 patients with HF from two observational studies in three hospitals in Korea. The structural equation model using AMOS version 24.0 was constructed to assess the relationships among the variables. The Seoul Neuropsychological Screening Battery was used to assess global cognition, immediate/delayed memory, and executive function, and the Self-Care of HF Index v.6.2. was used for self-care confidence and maintenance.

Results

Self-care maintenance was affected by memory function with a significant direct effect (β=.43, p = .006), as well as self-care confidence (β=.70, p < .001). Memory function and global function indirectly affected self-care maintenance through self-care confidence (β = -.37, p = .002; β = .14, p = .030). Depressive symptoms also had an indirect effect through self-care confidence on self-care maintenance (β = -.21, p = .005).

Conclusion

This study confirmed that it is important to increase self-care confidence through supportive care and to maintain memory function for maintaining self-care in the chronic course of HF patients. In particular, this study suggests that it is necessary to perform periodic memory check-ups for chronic HF patients on an outpatient basis, and counseling and education are needed to improve memory and increase confidence in self-care.

Trajectory of self-care in people with stable heart failure and insomnia after two self-care interventions

OBJECTIVE

To describe (1) self-care trajectories among adults with heart failure (HF) and insomnia over 1-year; (2) the extent to which trajectories varied between cognitive behavioral therapy for insomnia (CBT-I) or HF self-care intervention; and (3) the associations between self-care trajectories and clinical and demographic characteristics, sleep, symptoms and stress, and functional performance.

METHODS

We conducted secondary analysis of data from a randomized controlled trial of the effects of CBT-I compared with HF self-care education among adults with stable HF and insomnia. We used the Self-Care of Heart Failure Index v6.2. The analytic approaches included t-tests, group-based trajectory modeling, ANOVA, and chi-square.

RESULTS

We included 175 participants (M age=63.0 (12.9) years, White, N = 100]. We found four self-care trajectories: Low self-care (N = 47, 26.8%); Moderate self-care (N = 68, 38.9%): Adequate self-care (N = 42, 24.0%); and Optimal self-care (N = 18, 10.3%). There was no difference in self-care trajectories between interventions. The low self-care group had the most severe baseline fatigue, anxiety, and perceived stress, and lowest cognitive abilities.

CONCLUSION

Both interventions prevented declining self-care. Future research is needed to determine the most efficacious intervention to improve self-care trajectories.

PRACTICE IMPLICATIONS

Healthcare providers should provide ongoing self-care support for those with persistently low and moderate self-care.

Health-Related Quality of Life Trajectories Among Older Adults With Diabetes Mellitus: A Group-Based Modeling Approach

BACKGROUND

Health-related quality of life (HR-QoL) is an important issue among older adults with diabetes mellitus. However, information on longitudinal changes in HR-QoL over time using the illness trajectory model is limited.

PURPOSE

The purpose of this study was to identify patterns of temporal change in HR-QoL and their predictors using longitudinal data and a group-based modeling approach.

METHODS

European Quality of Life-5 Dimensions data for 440 older adults with diabetes mellitus were drawn from the nationwide Korea Health Panel Survey conducted from 2009 to 2013. Latent class growth analysis and multinomial logistic regression models were used to identify the predictors of HR-QoL trajectories.

RESULTS

Four distinct classes of HR-QoL trajectory were identified: high decrease (n = 46, 10.5%), high stable (n = 232, 52.7%), medium stable (n = 157, 35.7%), and low increase (n = 5, 1.1%). Participants in ``high decrease" and ``high-stable" classes tended to be men who were highly educated, physically active, and adherent to their medication regimen. High economic status, few chronic diseases, independence in activities of daily living, and high self-rated health status were also identified as indicators of being in the ``high-decrease" and ``high-stable" class group.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

A salient finding of this study is that HR-QoL trajectories in older adults with diabetes mellitus are not homogeneous but instead diverge into four distinct classes. Most participants showed no major changes in HR-QoL across the 5-year period, regardless of HR-QoL level. To prevent patients with diabetes from experiencing chronically low levels of HR-QoL, comprehensive assessment and individualized care based on HR-QoL are necessary.

Self-care research: How to grow the evidence base? (reprint)

BACKGROUND AND OBJECTIVE

The number of studies in the area of self-care is growing and international researchers are increasingly developing self-care interventions to improve outcomes of individual patients and communities. However, growth of the evidence is still slow due to challenges with designing and testing self-care interventions. In this article we address major methodological challenges with regard to the definition of self-care, use of theory, and research design, intended to provide guidance to researchers in this field.

METHOD

During the inaugural conference of the International Center for Self-Care Research held in Rome, Italy in June 2019 we identified important issues in existing self-care research. Discussion and literature review lead to eight recommendation for future self-care research.

RESULTS

In preparation, begin with a theoretically sound definition of self-care. In planning the intervention, build on and extend previous studies. Use theory to develop self-care interventions and consider translational models to guide development, evaluation and implementation of complex self-care interventions. Employ a study design that fits the current phase and objectives of the research and measure self-care and related factors carefully. In reporting, describe the sample and setting sufficiently so that others can draw conclusions about generalizability and applicability to their practice and patient population. In interpretation, describe how the intervention is assumed to work (causal assumptions) and its key components.

CONCLUSION

Our review of existing self-care research clearly illustrates that the recommendations we provide are needed if we are to substantially grow the evidence base supporting self-care. Embracing a core set of principles will allow us to build on each other's work. Tweetable abstract: A core set of methodological principles is needed to substantially grow the evidence base supporting self-care.

Sociodemographic Indicators of Social Position and Self-care Maintenance in Adults with Heart Failure

Social determinants of health (SDH) are known to influence health. Adequate self-care maintenance improves heart failure (HF) outcomes. However, the relationship between self-care maintenance and SDH remains unclear. Explore the relationship between sociodemographic indicators of social position and self-care maintenance in adults with HF. This was a secondary analysis of data from a cross-sectional descriptive study of 543 adults with HF. Participants completed the Self-Care of HF Index and a sociodemographic survey. We used multiple regression with backward elimination to determine which SDH variables were determinants of self-care maintenance. Marital status (p = .02) and race (p = .02) were significant determinants of self-care maintenance. Education (p = .06) was highest in Whites (35.6%). These variables explained only 3.8% of the variance in self-care maintenance. Race, education, and marital status were associated with HF self-care maintenance. SDH is complex and cannot be explained with simple sociodemographic characteristics.

The psychological impact of a nurse-led proactive self-care program on independent, non-frail community-dwelling older adults: A randomized controlled trial

BACKGROUND

Poor mental health is common later in life and is a crucial factor in determining older adults' ability to live independently in the community. Existing nurse-led proactive self-care programs for older adults focus on physical health, since many are living with chronic diseases. Little is known about their effectiveness on the psychological outcomes of independent, non-frail community-dwelling older adults.

AIM

The aim of this study was to examine the impact of a nurse-led proactive self-care program with a health-social partnership model for community-dwelling older adults on depressive symptoms, life satisfaction, and the mental component of health-related quality of life.

DESIGN AND METHODS

This was a single-blinded, randomized controlled trial. Adults aged 60 or over who lived within the service areas and scored ≥ 18 in the Mini-Mental Status Examination were included. Data were collected using questionnaires pre- (T1), post- (T2), and three month after the intervention (T3). The program provided a comprehensive assessment, health and self-management information, and empowerment, and promoted the accessibility of community services by building a health-social partnership network in the community. Generalized Estimating Equation was used to calculate the group, time, and interaction effects. Intention-to-treat was employed as the primary analysis in this study.

RESULTS

Of the 843 potential community-dwelling older adults who were assessed for eligibility, 457 eligible participants were randomized into the intervention (n = 230) or control group (n = 227). Among them, 175 (76.0%) participants in the intervention group and 190 (83.7%) participants in the control group completed data collection at T3, 6 months after T2 at the completion of the program. The results showed a significant time effect between T1 and T2 (Wald χ2 = 25.7, p < .001) and T1 and T3 (Wald χ2 = 7.40, p = .007) in terms of the presence of depressive symptoms.

CONCLUSIONS

Interprofessional care addressing health and social needs improves the depressive symptoms among older adults dwelling in the community.

Perspectives of Health Care Providers on the Role of Culture in the Self-Care of Patients with Chronic Heart Failure: A Qualitative Interview Study

Background: Self-care is important in chronic diseases such as heart failure. The cultural background of health care providers might influence their view on self-care behaviour and education they provide. The aim of this study was to describe health care providers’ perceptions of the role of culture in self-care and how those perceptions shape their experiences and their practices. Methods: A qualitative study was performed in Israel, a country with a culturally diverse population. Data were collected using semi-structured interviews with 12 healthcare providers from different cultural backgrounds. Interviews were recorded and transcribed verbatim and analysed using content analysis. Results: Healthcare providers experienced cultural background influenced their patients’ self-care behaviour. Perceived culture-specific barriers to self-care such as dietary traditions interfering with the recommended diet, willingness to undertake self-care and beliefs conflicting with medical treatment were identified. Healthcare providers described that they adapted patient education and care based on the cultural background of the patients. Shared cultural background, awareness and knowledge of differences were described as positively influencing self-care education, while cultural differences could complicate this process. Conclusions: Cultural-specific barriers for self-care were perceived by health care providers and they identified that their own cultural background shapes their experiences and their practices.

Identifying subgroups: Part 2: Trajectories of change over time

Methods to identify multiple trajectories of change over time are of great interest in nursing and in related health research. Latent growth mixture modeling is a data-centered analytic strategy that allows us to study questions about distinct trajectories of change in key measures or outcomes of interest. In this article, a worked example of latent growth mixture modeling is presented to help expose researchers to the use and appeal of this analytic strategy.

Testing the Effect of a Home Health Heart Failure Intervention on Hospital Readmissions, Heart Failure Knowledge, Self-Care, and Quality of Life

For older adults, heart failure (HF) has the highest 30-day hospital readmission rate of any chronic illness. Despite research into strategies to reduce readmissions, no single program has emerged as sustainable. The purpose of the current study was to test a researcher-developed home health nurse HF intervention (CareNavRN^™) on 30-day readmission rates, HF knowledge, self-care, and quality of life (QOL) among 40 older adults transitioning home. Home health nurses received specialized HF training and visited patients once per week at home for 4 weeks. The control group (n = 21) had six readmissions (29%) and the intervention group (n = 19) had three readmissions (16%); however, the results were underpowered and statistically nonsignificant. Pre-/post-surveys demonstrated significant improvement in HF knowledge (p = 0.043), self-care confidence (p = 0.003), and QOL (p < 0.001) in the intervention group. CareNavRN is a promising approach to improve outcomes during transition from hospital to home for patients without access to a comprehensive disease management program.

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

BACKGROUND

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

AIMS

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

METHODS

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

RESULTS

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

CONCLUSION

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

Application of self-care based on full-course individualized health education in patients with chronic heart failure and its influencing factors

BACKGROUND

The treatment of heart failure not only needs to relieve the clinical symptoms and improve the quality of life for patients but also needs to select scientific and reasonable ways to prevent or delay the progression of the disease, thus reducing the mortality and hospitalization rate. Although the previous regimen can effectively relieve symptoms in the early stage of treatment, long-term use may cause adverse events, such as arrhythmia, and even increase mortality. Therefore, conventional treatment cannot meet the actual health needs of patients, and scientific nursing intervention is very necessary.

AIM

To investigate the application of self-care based on full-course individualized health education (FCIHE) and its influencing factors in patients with chronic heart failure (CHF).

METHODS

We enrolled CHF patients who were admitted to our center between September 2015 and June 2016 and divided them into an intervention group (n = 50) and control group (n = 50) using a random number table. Routine nursing care was applied to the control group, and FCIHE was offered to the intervention group. The self-care behavior, 6-min walking distance (6MWD), and 36-item short form health survey (SF-36) scores were compared between the two groups. The influencing factors of the self-care were also analyzed.

RESULTS

The 6MWD was not significantly different between the two groups at admission (P > 0.05); however, at 3 and 6 mo after discharge, 6MWD was significantly increased, and it was significantly longer in the intervention group (P < 0.05). The scores for self-care behavior showed no significant difference at admission between the two groups (P > 0.05); however, at 3 and 6 mo after discharge, the total scores for self-care maintenance, management, confidence, and behavior of the intervention group were significantly higher than those of the control group (P < 0.05). There were no significant differences in the SF-36 scores at admission (P > 0.05); however, at 3 mo and 6 mo after discharge, the scores for all eight subscales, including physical functioning, role limitations due to physical problems, bodily pain, general health perceptions, vitality, social functioning, role-limitations due to emotional problems, and mental health, were significantly higher in the intervention group (P < 0.05). As shown by logistic regression analysis, the influencing factors of self-care mainly included age, cardiac function class, and education background (odds ratio > 1; all P < 0.05).

CONCLUSION

FCIHE improved self-care behavior and cardiac function in CHF patients. Age, cardiac function, and education level affected the implementation of self-care among CHF patients.

Predicting trajectories of recovery in prostate cancer patients undergone Robot-Assisted Radical Prostatectomy (RARP)

OBJECTIVE

To identify trends of patients' urinary and sexual dysfunctions from a clinical and psychological perspective and understand whether sociodemographic and medical predictors could differentiate among patients following different one-year longitudinal trajectories.

METHODS

An Italian sample of 478 prostate cancer patients undergone Robot-Assisted Radical Prostatectomy completed the EPIC-26 survey between July 2015 and July 2016 at the pre-hospitalization (T0), 45 days (T1) and 3 (T2), 6 (T3), 9 (T4), and 12 months (T5) after surgery. Sociodemographic and clinical characteristics (age, BMI, diabetes, nerve-sparing procedure) were also collected. Latent Class Growth Analysis was conducted separately for sexual dysfunction and urinary incontinence EPIC-26 subscales. The association between membership in the two longitudinal trajectories of urinary and sexual dysfunctions was assessed by considering Chi-square test and its related contingency table.

RESULTS

People who have a high level of urinary incontinence at T1 are likely to have a worse recovery. Age, BMI and pre-surgical continence may affect the level of incontinence at T1 and the recovery trajectories. Patients with low and moderate sexual problems at T1 can face a moderate linear recovery, while people with high level of impotence immediately after surgery may take a longer period to solve sexual dysfunctions. Age and the pre-surgical sexual condition may impact the recovery. Finally, a great proportion of patients reported both steady problems in sexual function and constant high levels of urinary incontinence over time.

CONCLUSIONS

This study highlights different categories of patients at risk who may be important to know in order to develop personalized medical pathways and predictive models in a value-based healthcare.

Patterns of adherence to diuretics, dietary sodium and fluid intake recommendations in adults with heart failure

BACKGROUND

Three behaviors advocated to minimize fluid-related hospitalizations in patients with heart failure (HF) are restricted sodium and fluid intake and consistent oral diuretic use. Adherence to behaviors intended to decrease risk of hospitalization is believed to vary over time, but surprisingly little research has addressed patterns of adherence in HF patients.

OBJECTIVE

To describe patterns over time of 3 recommended self-care behaviors (i.e., diet, fluid intake, and diuretic dosing) in adults with HF and to determine how time and behavior influenced adherence rates.

METHODS

We enrolled 24 adults hospitalized for a HF exacerbation and discharged on a loop diuretic into a descriptive, longitudinal pilot study. Over 3-months, diuretic use was measured using electronic event monitoring, and participants were telephoned regularly to assess sodium and fluid intake. Data were summarized for each 2-week intervals.

RESULTS

The overall adherence rates were 42.4% for low sodium diet, 96.4% for fluid restriction, and 84.7% for the diuretic regimen. Early after hospital discharge, medication adherence was the highest, and dietary adherence was the lowest, but adherence to diet and diuretic use decreased significantly over time.

CONCLUSION

Although participants were just discharged from the hospital after an acute exacerbation of HF, all three behavioral patterns decreased markedly over the 3-month follow-up period.
