Socio-clinical variables affecting the level of self-care in elderly patients with heart failure

Individual and systems-related factors associated with heart failure self-care: a systematic review

BACKGROUND

Heart failure (HF) is a prevalent condition worldwide. HF self-care is a set of behaviors necessary for improving patient outcomes. This study aims to review and summarize the individual and system-related factors associated with HF self-care published in the last seven years (Jan 2015 - Dec 2021) using the Socioecological Model as a review framework.

METHODS

An experienced nursing librarian assisted authors in literature searches of CINAHL Plus with Full Text, Ovid Nursing, PsychINFO, and PubMed databases for peer-reviewed descriptive studies. Inclusion criteria were HF sample with self-care as the outcome variable, and a quantitative descriptive design describing individual and/or system-level factors associated with self-care. Exclusion criteria were interventional or qualitative studies, reviews, published before 2015, non-English, and only one self-care behavior as the outcome variable. The search yielded 1,649 articles. Duplicates were removed, 710 articles were screened, and 90 were included in the full-text review.

RESULTS

A subset of 52 articles met inclusion and exclusion criteria. Study quality was evaluated using modified STROBE criteria. Study findings were quantitated and displayed based on socioecological levels. Self-care confidence, HF knowledge, education level, health literacy, social support, age, depressive symptoms, and cognitive dysfunction were the most frequently cited variables associated with self-care. Most factors measured were at the individual level of the Socioecological Model. There were some factors measured at the microsystem level and none measured at the exosystem or macrosystem level.

CONCLUSION

Researchers need to balance the investigation of individual behaviors that are associated with HF self-care with system-level factors that may be associated with self-care to better address health disparities and inequity.

Predictors of self-care behaviors in individuals with heart failure in Brazil

OBJECTIVE

To identify the predictors of self-care behaviors in individuals with heart failure.

METHOD

A cross-sectional study including 405 patients with heart failure. Self-care behaviors were assessed by the Self-Care of Heart Failure Index. Sociodemographic and clinical characteristics were investigated as predictors of self-care maintenance, management and confidence through logistic regressions.

RESULTS

The predictors of self-care maintenance were number of children (p<0.01), left ventricular ejection fraction (p<0.01), positive feeling about disease (p=0.03), obesity (p=0.02) and dialytic chronic kidney disease (p<0.01). The predictors of self-care management were having married children (p<0.01) and sleep apnea (p<0.01). The predictors of self-care confidence were family income (p<0.01), number of hospitalizations in the previous 12 months (p=0.01), number of daily medication doses (p<0.01) and sedentarism (p<0.01).

CONCLUSION

Some predictors related to the self-care behaviors were found, so some intensified education and social aid should be aimed at patients with these specific characteristics.

Characteristics of Patients Who Do Not Respond to Motivational Interviewing for Heart Failure Self-care

BACKGROUND

Motivational interviewing (MI) improves heart failure (HF) self-care for most yet fails to work for some patients. Identifying patients less likely to benefit from MI would save time in identifying a more suitable treatment for these patients.

OBJECTIVE

The aim of this study was to identify the characteristics of adults with HF less likely to clinically improve self-care after MI.

METHODS

This was a secondary intervention group analysis (n = 230) of MOTIVATional intErviewing to improve self-care in Heart Failure patients (MOTIVATE-HF), a trial evaluating MI in improving HF self-care maintenance and management. Self-care was measured with the Self-care of Heart Failure Index v. 6.2 at baseline and 3 months from enrollment. Participants were dichotomized into MI nonresponder (standardized score change <8 points) or MI responder (score change ≥8 points). Logistic regression, adjusted for group differences, identified determinants of nonresponse (odds ratio [95% confidence interval]).

RESULTS

Significant risk factors for self-care maintenance nonresponse 3 months after the intervention were nonischemic HF (2.58 [1.33-5.00], P = .005) and taking fewer medications (0.83 [0.74-0.93], P = .001). These variables explained 29.6% of the variance in HF self-care maintenance. Risk factors for self-care management nonresponse were living alone (4.33 [1.25-14.95], P = .021) and higher baseline self-care management (1.06 [1.02-1.09], P < .001), explaining 35% of the variance in HF self-care management.

CONCLUSIONS

Motivational interviewing may be less beneficial in patients with nonischemic HF and taking fewer medications. Patients with HF living alone with relatively better self-care management may be at risk for MI treatment failure. Identifying characteristics of nonresponders to MI in HF contributes to clinical decision making and personalized interventions.

The roles of health literacy and social support in improving adherence to self-care behaviours among older adults with heart failure

Aim

To describe the associations between health literacy, social support and self‐care behaviours in older adults with heart failure.

Design

A cross‐sectional descriptive study.

Methods

A total of 252 older adults were recruited from a tertiary care hospital from September 2018–February 2019. Structured questionnaires and medical record reviews were used for data collection. Two steps of hierarchical regression analysis were employed to determine the predictors of self‐care behaviours.

Results

Health literacy (β = 0.27, p < .001) and social support (β = 0.32, p < .001) were significant determinants of self‐care behaviours in older adults with heart failure. Together, they explained 22% of the variance in self‐care behaviours.

Conclusion

Health literacy and perceived social support were positively associated with self‐care behaviours among older heart failure patients. Our findings can help health professionals develop heart failure self‐care interventions to enhance health literacy skills and social support for older adults.
