Does cognitive impairment predict poor self-care in patients with heart failure?

Cognitive impairment in young and middle-aged patients with acute heart failure

AIMS

This study aimed to investigate the prevalence, risk factors and prognostic implications of cognitive impairment in young and middle-aged patients with acute heart failure (HF).

METHODS

In a prospective cohort of patients with acute HF, we assessed cognitive function by the Mini-Cog, predictors of the cognitive impairment and its associations with 30 day and 1 year cardiovascular death or HF rehospitalization among young and middle-aged patients (<65 years old).

RESULTS

Among 1958 young and middle-aged patients, the prevalence of cognitive impairment was 19.6%. Predictors of cognitive impairment included older age, females, lower education levels and prior strokes. Compared with patients having normal cognitive function, cognitive impairment was associated with a higher risk of 30 day cardiovascular death or HF rehospitalization [hazard ratio (HR), 1.52, 95% confidence interval (CI), 1.07-2.17, P = 0.02], but not for 1 year cardiovascular death or HF rehospitalization (HR, 1.06, 95% CI, 0.87-1.30, P = 0.55).

CONCLUSIONS

Cognitive impairment is present in a notable proportion of young and middle-aged patients with acute HF and is associated with an increased risk of short-term adverse outcomes. Strategies for screening and intervention for cognitive impairment at a younger age are necessary, particularly for those at high risk.

Trajectory of Cognitive Decline After Incident Heart Failure Hospitalization: Findings From the REGARDS Study

BACKGROUND

Cognitive impairment is common among adults with heart failure (HF) and associated with poor outcomes. However, less is known about the trajectory of cognitive decline after a first HF hospitalization. We examined the rate of cognitive decline among adults with incident HF hospitalization compared with those without HF hospitalization.

METHODS AND RESULTS

The REGARDS (Reasons for Geographic and Racial Differences in Stroke) study is a prospective longitudinal study of 23 894 participants aged ≥45 years free of HF at baseline. HF hospitalization was expert adjudicated. Changes in global cognitive function (primary outcome) were assessed with the Six-Item Screener (range, 0-6). Secondary outcomes included change in Word List Learning (range, 0-30), Word List Delayed Recall (WLD; range, 0-10), and Animal Fluency Test (range, 0+). Segmented linear mixed-effects regression models were used. Over 5 years, mean scores across all 4 cognitive tests declined for all participants regardless of HF status. Those with incident HF hospitalization experienced faster declines in the Six-Item Screener versus those who were HF free (difference, -0.031 [95% CI, -0.047 to -0.016]; P<0.001), a finding that persisted in fully adjusted models. Those with incident HF hospitalization did not experience faster declines in Word List Learning, Word List Delayed Recall, or Animal Fluency Test scores compared with those without HF hospitalization. Participants with hospitalization for HF with preserved, compared with reduced, ejection fraction had faster decline in Animal Fluency Test.

CONCLUSIONS

Global cognitive decline occurred faster among adults with incident HF hospitalization compared with those who remained free of HF hospitalization. This pattern was not seen for the other cognitive domains.

Effects of SGLT2-Inhibitors on Comprehensive Geriatric Assessment, Biomarkers of Oxidative Stress, and Platelet Activation in Elderly Diabetic Patients with Heart Failure with Preserved Ejection Fraction

BACKGROUND

Heart failure (HF) with preserved ejection fraction (HFpEF) represents a major comorbidity in the elderly and is associated with cognitive impairment (CoI) and type 2 diabetes mellitus (T2DM). In this context, there is an increase in oxidative stress and platelet activation biomarkers. The aim of this study was to evaluate the effects of 6 months' treatment with SGLT2i on functional, mood-related, and cognitive aspects, assessed by performing a comprehensive geriatric assessment (CGA), and on oxidative stress and platelet activation biomarkers, in a cohort of HFpEF elderly patients with T2DM. We recruited 150 elderly outpatients (mean age 75.8 ± 7.4 years).

RESULTS

At six-month follow-up, there was a significant improvement in MMSE (p < 0.0001), MoCA (p < 0.0001), GDS score (p < 0.0001), and SPPB (p < 0.0001). Moreover, we observed a significant reduction in Nox-2 (p < 0.0001), 8-Isoprostane (p < 0.0001), Sp-Selectin (p < 0.0001), and Gp-VI (p < 0.0001). Considering ΔMMSE as the dependent variable, ΔE/e', ΔNox-2, ΔHOMA, Δ8-Isoprostane, and ΔUricemia were associated for 59.6% with ΔMMSE. When ΔMoCA was considered as the dependent variable, ΔHOMA, ΔE/e', Δ8-Isoprostane, ΔNox-2 and ΔUricemia were associated for 59.2%. Considering ΔGDS as the dependent variable, ΔHOMA, ΔNox-2, Δ8-Isoprostane, and ΔUricemia were associated with 41.6% of ΔGDS variation. Finally, ΔHOMA was the main predictor of ΔSPPB, which was associated with 21.3% with ΔSPPB, Δ8-Isoprostane, ΔNox-2, ΔE/e', and ΔUricemia added another 24.1%.

CONCLUSION

The use of SGLT2i in elderly patients with T2DM and HFpEF significantly contributes to improving CGA scales and biomarkers of OS and PA.

Self-care behavior and associated factors among adult heart failure patients in outpatient cardiac follow-up unit at Wachemo University Nigist Eleni Comprehensive Specialized Hospital, Southern Ethiopia

BACKGROUND

Heart failure is a serious medical condition that occurs when the heart is unable to pump sufficient blood to meet the needs of the tissues. Good self-care is an essential behavior in long term management and maintenance of physiologic stability, better medical and person-centered outcomes. Poor self-care behavior deteriorates the outcomes of heart failure patients. However, there were no sufficient evidences that illustrate the topic in the country, including the study area.

METHODOLOGY

Institutional based cross-sectional study was conducted among 250 heart failure patients from July 5-August 4, 2021. All adult heart failure patients who fulfill the inclusion criteria and have appointment during study period were included in the study. Interview and medical chart review was used to collect data. Epidata version 3.1 and SPSS version 20 were used for data entry and analysis respectively. Bivariate and multivariable analysis was computed. The model fitness was checked by Hosmer and Lemeshow test.

RESULTS

From the total patients, 240 were interviewed with the response rate of 96%. Among these, 140(58.3%) [95% CI: 52.6, 64.9] had poor self-care behavior. Age>54: 9.891 [2.228, 43.922], poor knowledge: 6.980[1.065, 45.727], depression: 4.973[1.107, 22.338], low social support: 6.060[1.373, 26.739], insomnia: 4.801[1.019, 22.622] and duration with heart failure <1 year: 5.782[1.438, 23.247] were factors associated with poor self-care behavior.

CONCLUSION

In this study, more than half of participants attending at Wachemo University Nigist Eleni Comprehensive Specialized Hospital in outpatient cardiac follow-up unit had poor self-care behavior. Of the study variables, older age, poor knowledge, depressive symptoms, low social support, insomnia and short duration with heart failure were related with poor self-care behavior. Thus, the findings highlight importance of assessing level of self-care behavior and implicate direction to take action to enhance level of self-care behavior.

Disparities in 30-Day Readmission Between Medicare/Medicaid and Private Insurance Among Patients With Heart Failure Screened for Cognitive Impairment

BACKGROUND

Racial disparities exist among patients with heart failure (HF). HF is often comorbid with cognitive impairment. Appropriate self-care can prevent HF hospital readmissions but requires access to resources through insurance. Racial differences exist between insurance types, and this may influence the disparity between races and patients with HF and cognitive impairment.

OBJECTIVE

The objectives of this study were to examine the relationships between insurance type and self-care stratified by race and to assess for differences in time-to-30-day readmission among patients with HF with cognitive impairment.

METHODS

This is a secondary analysis of data collected among hospitalized patients with HF with cognitive impairment. Patients completed surveys on self-care (Self-Care of Heart Failure Index), HF knowledge (Dutch Heart Failure Knowledge Scale), depression (Geriatric Depression Scale), and social support (Enhancing Recovery in Coronary Heart Disease Social Support Inventory). Socioeconomic data were collected. Linear models were created to examine the relationships between insurance type and self-care by race. Kaplan-Meier curves and Cox regression were used to assess readmission.

RESULTS

The sample of 125 patients with HF with cognitive impairment was predominantly Black (68%, n = 85) and male (53%, n = 66). The sample had either Medicare/Medicaid (62%, n = 78) or private insurance (38%, n = 47). Black patients with HF with cognitive impairment and private insurance reported higher self-care confidence compared with Black patients with HF with cognitive impairment and Medicare/Medicaid ( P < .05). Medicare/Medicaid was associated with a higher frequency of 30-day readmission and a faster time-to-readmission.

CONCLUSIONS

Patients with HF with cognitive impairment and Medicare/Medicaid insurance reported lower self-care confidence and more likely to be readmitted within 30 days.

The Influence of Caregiver Contribution to Self-care on Symptom Burden in Patients With Heart Failure and the Mediating Role of Patient Self-care: A Longitudinal Mediation Analysis

BACKGROUND

Patients with heart failure experience high symptom burden, which can be mitigated with adequate self-care. Caregiver contribution to self-care has been theorized to improve patient symptom burden. The mediating role of patient self-care in this relationship has not been tested yet.

OBJECTIVES

The aim of this study was to test whether ( a ) caregiver contribution to self-care influences patient self-care, ( b ) patient self-care influences symptom burden, and ( c ) patient self-care mediates the relationship between caregiver contribution to self-care and symptom burden.

METHODS

In this study, the authors conducted a secondary analysis of the baseline and 3-month data from the MOTIVATE-HF trial, which enrolled 510 dyads (patient with heart failure and caregiver) in Italy. Multigroup confirmatory factor analysis was used to test measurement invariance. Autoregressive longitudinal path analysis with contemporaneous mediation was used to test our hypotheses.

RESULTS

On average, caregivers were 54 years old and mainly female, whereas patients were 72.4 years old and mainly male. Better caregiver contribution to self-care maintenance was associated with better patient self-care maintenance (β = 0.280, P < .001), which, in turn, was associated with lower symptom burden (β = -0.280, P < .001). Patient self-care maintenance mediated the effect of caregiver contribution to self-care maintenance on symptom burden (β = -0.079; 95% bias-corrected bootstrapped confidence interval, -0.130 to -0.043). Better caregiver contribution to self-care management was associated with better patient self-care management (β = 0.238, P = .006). The model significantly accounted for 37% of the total variance in symptom burden scores ( P < .001).

CONCLUSIONS

This study expands the situation-specific theory of caregiver contribution to heart failure self-care and provides new evidence on the role of caregiver contribution to self-care and patient self-care on symptom burden in heart failure.

Mediators of the Association Between Cognitive Function and Self-care Behaviors in Patients Hospitalized With an Exacerbation of Heart Failure

BACKGROUND

Patients with heart failure (HF) must engage in self-care, yet their self-care is often poor. Cognitive function commonly is impaired in HF and is associated with poor self-care. Heart failure knowledge and self-care confidence also are needed to preform self-care. Few investigators have examined mediators of the association of cognitive function with self-care.

OBJECTIVES

The aim of this study was to determine whether HF knowledge and self-care confidence mediated the association of cognitive function with self-care maintenance and management among patients with HF.

METHODS

This was a cross-sectional observational study of 164 patients with HF. Cognitive function was assessed using the Montreal Cognitive Assessment. Self-care maintenance and self-care management behaviors and self-care confidence were measured using the Self-care of Heart Failure Index. Heart failure knowledge was measured using the Dutch Heart Failure Knowledge Scale. We conducted 2 parallel mediation analyses using the PROCESS macro in SPSS, one for self-care maintenance and one for self-care management.

RESULTS

Cognitive function was indirectly associated with self-care maintenance through HF knowledge (indirect effect, 0.54; 95% confidence interval, 0.10-1.02) and self-care confidence (indirect effect, 0.26; 95% confidence interval, 0.04-0.54). Those with better cognitive function had more HF knowledge and self-care confidence. Better cognitive function was not directly associated with self-care management but indirectly associated with better self-care management through higher self-care confidence (indirect effect, 0.50; 95% confidence interval, 0.04-1.05).

CONCLUSIONS

Both HF knowledge and self-care confidence mediated the association of cognitive function with self-care maintenance, and only self-care confidence mediated the association between cognitive function and self-care management. Interventions targeting HF knowledge and self-care confidence may improve self-care even for those with lower cognitive function and need to be developed and tested.

Effect of Reliable Recovery on Health Care Costs and Productivity Losses in Emotional Disorders

Despite the high economic costs associated with emotional disorders, relatively few studies have examined the variation in costs according to whether the patient has achieved a reliable recovery. The aim of this study was to explore differences in health care costs and productivity losses between primary care patients from a previous randomized controlled trial (RCT)-PsicAP-with emotional symptoms who achieved a reliable recovery and those who did not after transdiagnostic cognitive-behavioral therapy (TD-CBT) plus treatment as usual (TAU) or TAU alone. Sociodemographic and cost data were obtained for 134 participants treated at five primary care centers in Madrid for the 12-month posttreatment period. Reliable recovery rates were higher in the patients who received TD-CBT + TAU versus TAU alone (66% vs. 34%, respectively; chi-square = 13.78, df = 1, p < .001). Patients who did not achieve reliable recovery incurred more costs, especially associated with general practitioner consultations (t = 3.01, df = 132, p = .003), use of emergency departments (t = 2.20, df = 132, p = .030), total health care costs (t = 2.01, df = 132, p = .040), and sick leaves (t = 1.97, df = 132, p = .048). These findings underscore the societal importance of achieving a reliable recovery in patients with emotional disorders, and further support the value of adding TD-CBT to TAU in the primary care setting.

Cognitive Impairment in Heart Failure: A Heart Failure Society of America Scientific Statement

Cognitive impairment is common among adults with heart failure (HF), as both diseases are strongly related to advancing age and multimorbidity (including both cardiovascular and noncardiovascular conditions). Moreover, HF itself can contribute to alterations in the brain. Cognition is critical for a myriad of self-care activities that are necessary to manage HF, and it also has a major impact on prognosis; consequently, cognitive impairment has important implications for self-care, medication management, function and independence, and life expectancy. Attuned clinicians caring for patients with HF can identify clinical clues present at medical encounters that suggest cognitive impairment. When present, screening tests such as the Mini-Cog, and consideration of referral for comprehensive neurocognitive testing may be indicated. Management of cognitive impairment should focus on treatment of underlying causes of and contributors to cognitive impairment, medication management/optimization, and accommodation of deficiencies in self-care. Given its implications on care, it is important to integrate cognitive impairment into clinical decision making. Although gaps in knowledge and challenges to implementation exist, this scientific statement is intended to guide clinicians in caring for and meeting the needs of an increasingly complex and growing subpopulation of patients with HF.

Cognitive impairment in heart failure patients: association with abnormal circadian blood pressure rhythm: a review from the HOPE Asia Network

Cognitive impairment (CI) is frequently a comorbid condition in heart failure (HF) patients, and is associated with increased cardiovascular events and death. Numerous factors contribute to CI in HF patients. Decreased cerebral blood flow, inflammation, and activation of neurohumoral factors are all thought to be factors that exacerbate CI. Hypoperfusion of the brain due to decreased systemic blood flow, cerebral venous congestion, and atherosclerosis are the main mechanism of CI in HF patients. Abnormal circadian BP rhythm is one of the other conditions associated with CI. The conditions in which BP does not decrease sufficiently or increases during the night are called non-dipper or riser BP patterns. Abnormal circadian BP rhythm worsens CI in HF patients through cerebral congestion during sleep and atherosclerosis due to pressure overload. Interventions for CI in HF patients include treatment for HF itself using cardiovascular drugs, and treatment for fluid retention, one of the causes of abnormal circadian rhythms. Proposed pathways of cognitive impairment in heart failure through abnormal circadian blood pressure rhythm.

Effects of remote patient management on self-care behaviour in heart failure patients: results from the randomized TIM-HF2 trial

AIMS

Remote patient management (RPM) in heart failure (HF) patients has beneficial clinical effects. This analysis investigates the effects of RPM used in the Telemedical Interventional Management in Heart Failure II (TIM-HF2) trial on HF-specific self-care.

METHODS AND RESULTS

From 2013 to 2017, 1538 HF outpatients (age 70.3 ± 10.5 years, 70% men, 52%/47% NYHA II/III, 65% LVEF ≤45%) with a recent HF hospitalization were included to the study and randomized to usual care (UC) plus RPM (n = 796) or UC only (n = 775), with a 12-month follow-up. Self-reported self-care behaviour at baseline and at end of study was assessed with the 9-item European Heart Failure Self-care Behaviour Scale (EHFScBS-9), obtaining 1321 patients with valid baseline and follow-up questionnaires for the analysis. EHFScBS-9 sum scores increased in the RPM group (n = 667) from 78.7 ± 17 to 84.5 ± 14 and in the UC group (n = 654) from 79.0 ± 17 to 80.0 ± 16 from baseline to 12 months [difference in means (MD) 4.58 (3.02, 6.14); P < 0.001] with highest improvement [8.66 (3.52; 13.81)] in patients living alone and having an inadequate (<70) baseline EHFScBS-9. There were differences between both groups in item 'I weight myself every day' [MD -1.13 (-1.24, -1.02); P < 0.001] and item 'I take my medication as prescribed' [MD -0.06 (-0.10, -0.01); P = 0.014]. No correlation was found between the EHFScBS-9 score and the efficacy of RPM on the TIM-HF2 primary endpoint of percentage of days lost due to unplanned cardiovascular hospitalization or death of any cause.

CONCLUSIONS

RPM improves HF-specific self-care behaviour by achieving a better adherence to recommended HF regimen.

Childbirth self-efficacy and fear of childbirth and their predictors in adolescent and adult pregnant women referring to health centres of Urmia-Iran: a cross-sectional study

OBJECTIVE

Adolescent pregnancy as a growing phenomenon in the world has been investigated from different aspects. However, the examination of childbirth fear and self-efficacy has received less attention. Therefore, this study was conducted to compare the self-efficacy and fear of childbirth and to determine their predictors in adolescent and adult pregnant women.

DESIGN

In this comparative cross-sectional study, participants were selected through two-stage cluster sampling method. Data were collected using the Childbirth Self-Efficacy Inventory and Wijma Delivery Expectancy/Experience Questionnaire. The Pearson correlation test, independent t-test, and general linear model were used for data analysis.

SETTING

Urmia health centres, Iran in 2020.

PARTICIPANTS

Three hundred and sixty adults and adolescent pregnant women.

RESULTS

The mean (SD) of fear of childbirth was 114.7 (14.1) and 108.1 (23.1) in adolescent and adult pregnant women, respectively. The mean (SD) of childbirth self-efficacy in the active phase and the second stage of labour respectively were also obtained 208.8 (28.6) and 203.5 (32.1) for adolescent pregnant women and 213.8 (25.7) and 212.0 (26.5) for adult ones. There was a significant difference between adolescent and adult pregnant women in fear of childbirth (p=0.001), self-efficacy expectancy (p=0.003) and total childbirth self-efficacy (p=0.008) in the second stage of labour. After adjusting the sociodemographic characteristics, the mean score of fear of childbirth was significantly higher in adolescent pregnant women than in adult ones whereas the mean total self-efficacy score in the second stage of labour was significantly lower in adolescent pregnant women than in adult ones.

CONCLUSION

This study showed that adolescent pregnant women had more fear of childbirth and low self-efficacy than adult mothers, and there was also a relationship between fear of childbirth and self-efficacy. Paying more attention to fear and self-efficacy in childbirth and their predictors by health providers can improve pregnancy and childbirth outcomes.

A Prospective Cohort Study of Medical Decision-Making Roles and Their Associations with Patient Characteristics and Patient-Reported Outcomes among Patients with Heart Failure

OBJECTIVE

Among patients with heart failure (HF), we examined 1) the evolution of patient involvement in decision making over 2 y, 2) the association of patient characteristics with decision-making roles, and 3) the association of decision-making roles with distress, spiritual well-being, and quality of physician communication.

METHODS

We administered the survey every 4 mo over 24 mo to patients with New York Heart Association class 3/4 symptoms recruited from inpatient clinics. The decision-making roles were categorized as no patient involvement, physician/family-led, joint (with family and/or physicians), patient-led, or patient-alone decision making. The associations between patient characteristics and decision-making roles were assessed using a mixed-effects ordered logistic regression, whereas those between patient outcomes and decision-making roles were investigated using mixed-effects linear regressions.

RESULTS

Of the 557 patients invited, 251 participated in the study. The most common roles in decision making at baseline assessment were "no involvement" (27.53%) and "patient-alone decision making" (25.10%). The proportions of different decision-making roles did not change over 2 y (P = 0.37). Older age (odds ratio [OR] = 0.97; P = 0.003) and being married (OR = 0.63; P = 0.035) were associated with lower involvement in decision making. Chinese ethnicity (OR = 1.91; P = 0.003), higher education (OR = 1.87; P = 0.003), awareness of terminal condition (OR = 2.00; P < 0.001), and adequate self-care confidence (OR = 1.74; P < 0.001) were associated with greater involvement. Compared with no patient involvement, joint (β = -0.58; P = 0.026) and patient-led (β = -0.59; P = 0.014) decision making were associated with lower distress, while family/physician-led (β = 4.37; P = 0.001), joint (β = 3.86; P < 0.001), patient-led (β = 3.46; P < 0.001), and patient-alone (β = 3.99; P < 0.001) decision making were associated with better spiritual well-being.

CONCLUSION

A substantial proportion of patients was not involved in decision making. Patients should be encouraged to participate in decision making since it is associated with lower distress and better spiritual well-being.

HIGHLIGHTS

The level of involvement in medical decision making did not change over time among patients with heart failure. A substantial proportion of patients were not involved in decision making throughout the 24-mo study period.Patients' involvement in decision making varied by age, ethnicity, education level, marital status, awareness of the terminal condition, and confidence in self-care.Compared with no patient involvement in decision making, joint and patient-led decision making were associated with lower distress, and any level of patient involvement in decision making was associated with better spiritual well-being.

The effectiveness of cognitive-behavioral therapy for heart failure patients: a narrative review

Heart failure (HF) remains a major cause of morbidity, mortality and healthcare costs, despite available treatments. Psychological issues such as depression, anxiety and poor self-care are prevalent in HF patients. Such issues adversely affect patients' daily lives and increase hospitalization and mortality rates; therefore, effective approaches to address these are needed. Cognitive-behavioral therapy (CBT) has been proposed as potentially useful for psychological comorbidities in HF patients, but its efficacy is not well-established. This narrative review aimed to summarize the evidence on the effectiveness of CBT for HF patients. A search was conducted using PubMed and Google Scholar for randomized controlled trials (RCTs) on CBT for HF patients. Ten studies (nine RCTs and one case study) were included in the review. CBT was found to be an effective intervention for managing depression, anxiety, low quality of life, and impaired social and physical functioning in HF patients. The results suggest that CBT can improve psychological well-being and enhance the benefits of rehabilitation programs. Face-to-face CBT appears to be superior to conventional therapy and can be implemented in cardiac rehabilitation settings. Further research is needed to evaluate the efficacy of internet-based CBT for cardiac patients and identify factors that promote treatment adherence.

Short term effect of sacubitril/valsartan on comprehensive geriatric assessment in chronic heart failure: a real life analysis

Sacubitril/Valsartan (Sac-Val) has improved clinical prognosis in patients affected by heart failure (HF) with reduced ejection fraction (HFrEF). Comorbidities have a crucial impact on clinical presentation and prognosis in HF patients. Cognitive impairment (CoI) and Depression are a very common comorbidity in patients with HF and is widely recognized as a specific determinant of chronic disability, and HF patients with poor physical functional performance in Short physical performance battery (SPPB) showed a worse prognosis. The aim of the present study was to evaluate the potential effects of Sac-Val on functional, humoral, and cognitive aspects, evaluated by performing comprehensive geriatric assessment (CGA), in a cohort of elderly HFrEF. We studied 61 patients (51 men and 10 women, mean age 76.4 ± 5.1 years) suffering from HFrEF. After 6 months follow-up, we observed a significant improvement in humoral and functional parameters of CGA, renal function, NTpro-BNP levels and echocardiographic parameters. In the whole population, multivariate analysis shows that changes of Cardiac Index, NT-proBNP and Respiratory rate contributed for 26.0%, 9.7% and 4.8% to GDS variability, respectively, and the whole model accounted for a 41.1% of GDS variation; moreover changes of Global longitudinal strain, estimated glomerular filtration rate, Cardiac Index and BMI contributed for 23.9%, 11.7%, 5.4% and 4.0% to SPPB variability, respectively, and the whole model accounted for a 45% of SPPB variation. This represents the first real-world study carried out in an elderly population suffering from chronic HFrEF with numerous comorbidities, in which treatment with Sac-Val for 6 months induced important improvements in clinical, humoral, hemodynamic, and functional outcomes, without adverse effects on cognitive performance.

Effectiveness of Motivational Interviewing on contribution to self-care, self-efficacy, and preparedness in caregivers of patients with heart failure: a secondary outcome analysis of the MOTIVATE-HF randomized controlled trial

AIMS

Caregiver characteristics and behaviours are associated with patients' and caregivers' outcomes. However, there is scarce evidence on interventions aimed at improving caregiver contribution (CC) to patient self-care, caregiver self-efficacy, and caregiver preparedness in heart failure (HF). This study aims to evaluate the effect of Motivational Interviewing (MI) on CC to patient self-care, caregiver self-efficacy, and caregiver preparedness in HF.

METHODS AND RESULTS

This is a secondary outcome analysis of MOTIVATE-HF randomized controlled trial. Caregivers of patients with HF were randomized into three arms: Arm 1 (MI for patients), Arm 2 (MI for patients and caregivers), and Arm 3 (standard care). The intervention consisted of one MI session plus three telephone contacts. Data were collected at baseline and after 3, 6, 9, and 12 months. A total of 510 patient and caregiver (median age 54 years, 76% females) dyads were enrolled, 235 caregivers and 238 patients completed the study until 12 months. Caregiver contribution to self-care maintenance and management and caregiver preparedness significantly improved over time, but without significant differences among the three arms. At 9 months, caregiver self-efficacy improved more in Arm 2 than Arm 3 [difference: 8.36, 95% confidence interval (CI) (3.13; 13.59), P = 0.001]. This improvement remained significant also at linear mixed model [β^ = 1.39, 95% CI (0.02; 2.75), P = 0.046].

CONCLUSION

Motivational Interviewing did not improve CC to patient self-care and caregiver preparedness. However, it increased caregiver self-efficacy, which is known to be a powerful mediator of CC to self-care.

Time to Revisit Heart Failure Self-Care: A Concept Analysis

Self-care is a central concept in heart failure management and nursing practice. Yet, the uptake of heart failure self-care has been uncritical and detached from broader contexts. Therefore, heart failure self-care was explored using Rodger's evolutionary concept analysis approach to identify antecedents, attributes, and consequences with attention to context, time, application, and meaning. The analysis suggests that heart failure self-care tends to focus on individual behaviors to the detriment of social and structural determinants of health. It also shifts responsibility away from the health care system and onto the individual. Moving forward, a more robust conceptualization of heart failure self-care is needed or possibly, the development of a new concept that focuses beyond the self .

Prevalence and factors associated with cognitive impairment in Chinese heart failure patients: A pilot study

Background

The prevalence of Cognitive impairment (CI) is high in patients with heart failure (HF). It leads to poor prognosis, such as self-care, hospital readmission and increased mortality. However, such information among Chinese population is unclear.

Objective

The purpose of this study was to examine the prevalence of CI in Chinese patients with HF, and explore its correlation with biomarkers and clinical factors to better manage HF patients with CI.

Methods

This study is a cross-sectional study of 200 hospitalized HF patients in China. The cognitive function of HF patients was assessed by the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE).

Results

The majority are male (62.5%, n = 125), have primary school and below level of education (57.5%, n = 115), NYHA III and above (62%, n = 124). They have an average MoCA score of 15.10 ± 8.18, MMSE score of 19.55 ± 8.23. Age, NYHA class, and atrial fibrillation were independently associated with CI (p &lt; 0.05). There was a significant association between CI and the 4th quartile of TNT (p = 0.013), and the 3rd and 4th quartile of NT-proBNP (p = 0.015, p = 0.038).

Conclusions

The prevalence of undiagnosed CI in Chinese HF patients is high (81%). HF patients with high levels of TNT or NT-proBNP or both values may be at risk of developing CI. Therefore, we suggest that HF patients with older age, atrial fibrillation, NYHA class II and III, as well as elevated TNT or NT-proBNP or both values to be followed up with a formal evaluation for CI. Nurses need to provide targeted health education program for cognitively impaired HF population to improve their self-care ability and nursing outcome.

The Utility of Cognitive Screening in Asian Patients With Heart Failure: A Systematic Review

Background

The prevalence of undiagnosed cognitive impairment in patients with heart failure is alarmingly high in Asia. There is still no consensus on cognitive screening tools to detect cognitive impairment in the Asian heart failure population. The clinical implications based on our systematic review may help to improve cognitive screening practice for patients with heart failure in Asia.

Methods

This review is registered in the PROSPERO (CRD42021264288). Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach, we searched PubMed, Embase, the Cumulative Index to Nursing and Allied Health Literature, Scopus, the Web of Science, PsycINFO, the Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, and Wanfang Data in English and Chinese literatures concerning heart failure and cognitive impairment.

Results

The search yielded 21 eligible studies. Only in five studies, cognitive brief tests, including the Montreal Cognitive Assessment (MoCA), the Mini-Mental State Examination (MMSE), and the Mini-Cog, were used as cognitive screening tools for Asian patients with heart failure. In the rest 16 studies, brief cognitive tests were used as screening tools for global cognition. Only one study validated screening tests against a gold standard formal neuropsychological assessment test battery. Among these studies, patients with heart failure tended to perform worse than patients without heart failure. The presence of cognitive impairment in patients with heart failure is associated with poorer self-care, quality of life, and hospital readmission.

Conclusion

Brief cognitive tests have been used in Asian patients with heart failure and these tests are frequently used as a measure of global cognitive function for cognitive screening. However, validating brief cognitive tests against a gold standard formal neuropsychological assessment in Asian patients with heart failure is lacking. Future studies need to address methodological issues to validate cognitive screening measures in a larger population of Asian patients with heart failure.Systematic Review Registration: https://www.crd.york.ac.uk/prospero/.

The Emerging Role of Combined Brain/Heart Magnetic Resonance Imaging for the Evaluation of Brain/Heart Interaction in Heart Failure

Heart failure (HF) patients frequently develop brain deficits that lead to cognitive dysfunction (CD), which may ultimately also affect survival. There is an important interaction between brain and heart that becomes crucial for survival in patients with HF. Our aim was to review the brain/heart interactions in HF and discuss the emerging role of combined brain/heart magnetic resonance imaging (MRI) evaluation. A scoping review of published literature was conducted in the PubMed EMBASE (OVID), Web of Science, Scopus and PsycInfo databases. Keywords for searches included heart failure, brain lesion, brain, cognitive, cognitive dysfunction, magnetic resonance imaging cardiovascular magnetic resonance imaging electroencephalogram, positron emission tomography and echocardiography. CD testing, the most commonly used diagnostic approach, can identify neither subclinical cases nor the pathophysiologic background of CD. A combined brain/heart MRI has the capability of diagnosing brain/heart lesions at an early stage and potentially facilitates treatment. Additionally, valuable information about edema, fibrosis and cardiac remodeling, provided with the use of cardiovascular magnetic resonance, can improve HF risk stratification and treatment modification. However, availability, familiarity with this modality and cost should be taken under consideration before final conclusions can be drawn. Abnormal CD testing in HF patients is a strong motivating factor for applying a combined brain/heart MRI to identify early brain/heart lesions and modify risk stratification accordingly.

Clinical benefit of combined assessment of physical and psychological frailty in patients with heart failure

OBJECTIVES

Physical frailty becomes a robust risk factor in patients with heart failure (HF) and coexistence of physical and psychological frailty is likely to be a prognostic indicator. This study aimed to analyze the prognosis of coexistence of these two factors in patients with HF.

METHODS

This study was a secondary analysis of a multicenter prospective cohort study (FLAGSHIP). We analyzed data from 2502 patients with HF from the FLAGSHIP study in Japan. We divided the patients into four physical frailty categories using a frailty score ranging from 0 to 14 (<4: I, 4-8: II, 9-12: III, and 14: IV, the score 13 does not exist in calculation). The higher category indicates more severe physical frailty. Psychological frailty was defined as the presence of cognitive decline and/or depressive symptoms. The study outcome was a 2-year composite outcome of rehospitalization for HF or all-cause mortality after hospital discharge.

RESULTS

During the 3734.7 person-year follow-up, 774 patients experienced the composite outcome. After adjusting for confounders, physical and psychological frailty were independently associated with adverse outcomes. Using physical frailty category I, without psychological frailty as the reference, adjusted hazard ratios for adverse outcomes were 1.29 [95% confidence interval (CI) 0.86-1.92] for category I with psychological frailty, 0.99 (95% CI 0.71-1.37) for category II without psychological frailty, 1.61 (95% CI 1.16-2.23) for category II with psychological frailty, 1.56 (95% CI 1.14-2.15) for category III without psychological frailty, 1.62 (95% CI 1.20-2.20) for category III with psychological frailty, 1.50 (95% CI 1.05-2.14) for category IV without psychological frailty, and 2.16 (95% CI 1.59-2.94) for category IV with psychological frailty, respectively.

CONCLUSIONS

Combined assessment of physical and psychological frailty leads to more detailed risk stratification of patients with HF.

Cognitive Impairment in Heart Failure: Landscape, Challenges, and Future Directions

Heart failure (HF) is a major global healthcare problem accounting for substantial deterioration of prognosis. As a complex clinical syndrome, HF often coexists with multi-comorbidities of which cognitive impairment (CI) is particularly important. CI is increasing in prevalence among patients with HF and is present in around 40%, even up to 60%, of elderly patients with HF. As a potent and independent prognostic factor, CI significantly increases the hospitalization and mortality and decreases quality of life in patients with HF. There has been a growing awareness of the complex bidirectional interaction between HF and CI as it shares a number of common pathophysiological pathways including reduced cerebral blood flow, inflammation, and neurohumoral activations. Research that focus on the precise mechanism for CI in HF is still ever insufficient. As the tremendous adverse consequences of CI in HF, effective early diagnosis of CI in HF and interventions for these patients may halt disease progression and improve prognosis. The current clinical guidelines in HF have begun to emphasize the importance of CI. However, nearly half of CI in HF is underdiagnosed, and few recommendations are available to guide clinicians about how to approach CI in patients with HF. This review aims to synthesize knowledge about the link between HF and cognitive dysfunction, issues pertaining to screening, diagnosis and management of CI in patients with HF, and emerging therapies for prevention. Based on data from current studies, critical gaps in knowledge of CI in HF are identified, and future research directions to guide the field forward are proposed.

Factors Associated With Cognitive Impairment in Heart Failure With Preserved Ejection Fraction

BACKGROUND

Cognitive impairment is prevalent in heart failure and is associated with higher mortality rates. The mechanism behind cognitive impairment in heart failure with preserved ejection fraction (HFpEF) has not been established.

OBJECTIVE

The aim of this study was to evaluate associations between abnormal cardiac hemodynamics and cognitive impairment in individuals with HFpEF.

METHODS

A secondary analysis of Atherosclerosis Risk in Communities (Atherosclerosis Risk in Communities) study data was performed. Participants free of stroke or dementia who completed in-person assessments at visit 5 were included. Neurocognitive test scores among participants with HFpEF, heart failure with reduced ejection fraction (HFrEF), and no heart failure were compared. Sociodemographics, comorbid illnesses, medications, and echocardiographic measures of cardiac function that demonstrated significant (P < .10) bivariate associations with neurocognitive test scores were included in multivariate models to identify predictors of neurocognitive test scores among those with HFpEF. Multiple imputation by chained equations was used to account for missing values.

RESULTS

Scores on tests of attention, language, executive function, and global cognitive function were worse among individuals with HFpEF than those with no heart failure. Neurocognitive test scores were not significantly different among participants with HFpEF and HFrEF. Worse diastolic function was weakly associated with worse performance in memory, attention, and language. Higher cardiac index was associated with worse performance on 1 test of attention.

CONCLUSIONS

Cognitive impairment is prevalent in HFpEF and affects several cognitive domains. The current study supports the importance of cognitive screening in patients with heart failure. An association between abnormal cardiac hemodynamics and cognitive impairment was observed, but other factors are likely involved.

Cognitive Impairment in Acute Heart Failure: Narrative Review

Cognitive impairment (CI) represents a common but often veiled comorbidity in patients with acute heart failure (AHF) that deserves more clinical attention. In the AHF setting, it manifests as varying degrees of deficits in one or more cognitive domains across a wide spectrum ranging from mild CI to severe global neurocognitive disorder. On the basis of the significant negative implications of CI on quality of life and its overwhelming association with poor outcomes, there is a compelling need for establishment of detailed consensus guidelines on cognitive screening methods to be systematically implemented in the population of patients with heart failure (HF). Since limited attention has been drawn exclusively on the field of CI in AHF thus far, the present narrative review aims to shed further light on the topic. The underlying pathophysiological mechanisms of CI in AHF remain poorly understood and seem to be multifactorial. Different pathophysiological pathways may come into play, depending on the clinical phenotype of AHF. There is some evidence that cognitive decline closely follows the perturbations incurred across the long-term disease trajectory of HF, both along the time course of stable chronic HF as well as during episodes of HF exacerbation. CI in AHF remains a rather under recognized scientific field that poses many challenges, since there are still many unresolved issues regarding cognitive changes in patients hospitalized with AHF that need to be thoroughly addressed.

Self-care: A concept analysis

Objectives

There is extensive literature from various disciplines on self-care, an important aspect of nursing intervention via evaluation and education, but its meaning remains unprecise due to the difficulty integrating the diverse definitions developed over time across disciplines. Therefore, it is vital to clarify the meaning of self-care and formulate the defining attributes, antecedents, and consequences to self-care.

Methods

Walker and Avant’s concept analysis approach was used to analyze the concept of self-care. A search of the literature was completed using the databases CINAHL, PubMed, and EBSCOhost for years 1975–2020; literature search included peer-review articles, full-text publications, and available in English. A total of 31 articles were reviewed, and saturation was reached.

Results

An extensive review of the literature revealed salient characteristics that reflected the most frequently used terms associated with the concept. Guided by Walker and Avant’s method, three defining attributes emerged as common themes: awareness, self-control, and self-reliance.

Conclusions

A clarified definition was identified: the ability to care for oneself through awareness, self-control, and self-reliance in order to achieve, maintain, or promote optimal health and well-being.

Pain and the Montreal Cognitive Assessment (MoCA) in Aging

OBJECTIVE

The present study aimed to determine whether specific cognitive domains part of the Montreal Cognitive Assessment (MoCA) are significantly lower in community-dwelling older adults with chronic pain compared with older adults without pain and whether these domains would be associated with self-reported pain, disability, and somatosensory function.

DESIGN

Secondary data analysis, cross-sectional.

SETTING

University of Florida.

SUBJECTS

Individuals over 60 years old enrolled in the Neuromodulatory Examination of Pain and mobility Across the Lifespan (NEPAL) study were included if they completed the MoCA and other study measures (n = 62). Most participants reported pain on most days during the past three months (63%).

METHODS

Subjects underwent a health assessment (HAS) and a quantitative sensory testing (QST) session. Health/medical history, cognitive function and self-reported pain measures were administered during the HAS. Mechanical and thermal detection, and thermal pain thresholds were assessed during the QST session.

RESULTS

Older adults with chronic pain had lower MoCA scores compared with controls on domains of executive function, attention, memory, and language (P < 0.05). The attention and language domains survived adjustments for age, sex, education, depression, and pain duration (P < 0.05). Attention was significantly associated with all pain characteristics including pain intensity and disability, while executive function was associated with mechanical detection (P < 0.05).

CONCLUSION

Our results support previous findings that individuals with chronic pain tend to show poorer cognitive functioning compared with pain-free controls in domains of attention and executive function. Our findings also extend these findings to community-dwelling older adults, who are already most vulnerable to age-related cognitive declines.

The Relationship Between Brain Fog and Medication Adherence for Individuals With Hypothyroidism

Individuals with hypothyroidism suffer from symptoms including impairments to cognition (i.e., "brain fog"). Medication can help reduce symptoms of hypothyroidism; however, brain fog may hinder adherence. The aim of this study was to determine if memory impairment and cognitive failures are related to treatment nonadherence in 441 individuals with hypothyroidism. Participants with a diagnosis of hypothyroidism and currently prescribed a thyroid hormone replacement medication were placed in two groups according to adherence level and compared on validated scales assessing impairments to memory and cognition. Results indicated a significant association between treatment nonadherence and self-reported brain fog, represented by greater cognitive and memory impairments. Nonadherent individuals indicated impairments with prospective, retrospective, and short- and long-term memory; and more cognitive failures, compared to adherent individuals. Findings suggest the importance of interventions to enhance adherence for individuals with brain fog, such as encouraging the use of reminders.

Do chronic heart failure symptoms interact with burden of treatment? Qualitative literature systematic review

OBJECTIVE

Explore the interaction between patient experienced symptoms and burden of treatment (BoT) theory in chronic heart failure (CHF). BoT explains how dynamic patient workload (self-care) and their capacity (elements influencing capability), impacts on patients' experience of illness.

DESIGN

Review of qualitative research studies.

DATA SOURCES

CINAHL, EMBASE, MEDLINE, PsycINFO, Scopus and Web of Science were searched between January 2007 and 2020.

ELIGIBILITY CRITERIA

Journal articles in English, reporting qualitative studies on lived experience of CHF.

RESULTS

35 articles identified related to the lived experience of 720 patients with CHF. Symptoms with physical and emotional characteristics were identified with breathlessness, weakness, despair and anxiety most prevalent. Identifying symptoms' interaction with BoT framework identified three themes: (1) Symptoms appear to infrequently drive patients to engage in self-care (9.2% of codes), (2) symptoms appear to impede (70.5% of codes) and (3) symptoms form barriers to self-care engagement (20.3% of codes). Symptoms increase illness workload, making completing tasks more difficult; simultaneously, symptoms alter a patient's capacity, through a reduction in their individual capabilities and willingness to access external resources (ie, hospitals) often with devasting impact on patients' lives.

CONCLUSIONS

Symptoms appear to be integral in the patient experience of CHF and BoT, predominately acting to impede patients' efforts to engage in self-care. Symptoms alter illness workload, increasing complexity and hardship. Patients' capacity is reduced by symptoms, in what they can do and their willingness to ask for help. Symptoms can lower their perceived self-value and roles within society. Symptoms appear to erode a patient's agency, decreasing self-value and generalised physical deconditioning leading to affective paralysis towards self-care regimens. Together describing a state of overwhelming BoT which is thought to be a contributor to poor engagement in self-care and may provide new insights into the perceived poor adherence to self-care in the CHF population.

CENTRAL AND PERIPHERAL SYMPATHETIC ACTIVATION IN HEART FAILURE

The sympathetic nervous system overdrive occurring in heart failure has been reported since more than half a century. Refinements in the methodological approaches to assess human sympathetic neural function have allowed during recent years to better define various aspects related to the neuroadrenergic alteration. These include 1) the different participation of the individual regional sympathetic cardiovascular districts at the process, 2) the role of the central nervous system in determining the neuroadrenergic overdrive, 3) the involvement of baroreflex, cardiopulmonary reflex and chemoreflex mechanisms in the phoenomenon, which is also closely linked to inflammation and the immune reaction, 4) the relationships with the severity of the disease, its ischaemic or idiopathic nature and the preserved or reduced left ventricular ejection fraction and 5) the adverse functional and structural impact of the sympathetic activation on cardiovascular organs, such as the brain, the heart and the kidneys. Information have been also gained on the active role exerted by the sympathetic activation on the disease outcome and its potential relevance as target of the therapeutic interventions based on non-pharmacological, pharmacological and invasive approaches, including the renal denervation, the splanchnic sympathetic nerve ablation and the carotid baroreflex stimulation. The still undefined aspects of the neurogenic alterations and the unmet goals of the therapeutic approach having the sympathetic activation as a target of the intervention will be finally mentioned.

Self-management on heart failure: A meta-analysis

BACKGROUND AND AIMS

Heart failure (HF) is a severe public health problem all over the World. Self-management is an effective method to progress self-care ability. However, the role of self-management in heart failure has not been thoroughly elucidated.

METHODS

The research articles related to heart failure were searched by the PubMed, Embase, Cochrane databases, and China National Knowledge Database on articles published through March 2020. The average 95% of confidence intervals (CIs) were used to calculate using random-effects or fixed-effects. Review Manager (version 5.2) was adopted for meta-analysis, sensitivity analysis, and bias analysis.

RESULTS

Eight (8) eligible studies with 1707 patients with HF were included in this analysis. In the Meta-analysis showed significant differences for Self-management (SM) groups in Dutch Heart Failure Knowledge Scale (DHFK) (MD = 1.36, 95%CI [-0.03, 2.75], P = 0.04; I² = 83%), in Self-Care of Heart Failure Index (SCHFI) (MD = 5.51, 95%CI [0.62, 10.40], P = 0.03; I² = 70%), and in Self-Efficacy for Managing Chronic Disease Scale (SEMCDI) (I² = 47%, Z = 5.43, P of over effect < 0.0001) than control groups. One bias is detected as attrition bias, and another one is reporting bias. Sensitivity analysis satisfied the stability of the results.

CONCLUSION

Self-management was associated with significant outcomes in patients with HF through knowledge, attitude, and practice (KAP).

Usefulness of the Japanese version of Rapid Dementia Screening Test for mild cognitive impairment in older patients with cardiovascular disease: a cross-sectional study

BACKGROUND

Cognitive decline is common among older patients with cardiovascular disease (CVD) and can decrease their self-management abilities. However, the instruments for identifying mild cognitive impairment (MCI) are not always feasible in clinical practice. Therefore, this study evaluated whether MCI could be detected using the Japanese version of the Rapid Dementia Screening Test (RDST-J), which is a simple screening tool for identifying cognitive decline.

METHODS

This retrospective single-center study included patients who were ≥ 65 years old and hospitalized because of CVD. Patients with a pre-hospitalization diagnosis of dementia were excluded. Each patient's cognitive function had been measured at discharge using the RDST-J and the Japanese version of the Montreal Cognitive Assessment (MoCA-J), which is a standard tool for MCI screening. The correlation between the two scores was evaluated using Spearman's rank correlation coefficient. Receiver operating characteristic (ROC) analysis was also to evaluate whether the RDST-J could identify MCI, which was defined as a MoCA-J score of ≤ 25 points.

RESULTS

The study included 78 patients (mean age: 77.2 ± 8.9 years). The RDST-J and MoCA-J scores were strongly correlated (r = 0.835, P < 0.001). The ROC analysis revealed that an RDST-J score of ≤ 9 points provided 75.4% sensitivity and 95.2% specificity for identifying MCI, with an area under the curve of 0.899 (95% CI: 0.835-0.964). The same cut-off value was identified when excluding patients with a high probability of dementia (RDST-J score of ≤ 4 points).

CONCLUSIONS

The RDST-J may be a simple and effective tool for identifying MCI in older patients with CVD.

Cognitive impairment as a determinant of response to management plans after heart failure admission

AIMS

Cognitive impairment (CI) is highly prevalent in heart failure (HF), and increases patients' risks of readmission. This study sought to determine whether the presence and degree of CI could identify patients most likely to benefit from a HF disease management programme (DMP) to reduce readmissions.

METHODS AND RESULTS

A total of 1152 consecutive Australian patients admitted with HF (2014-2017) were prospectively followed up for 12 months. Of these, 324 patients who received DMP (1-month duration, including post-discharge home visits, medication reconciliation, exercise guidance and early clinical review) were matched (1:2 ratio) with 648 usual care patients. Cognitive function was assessed either on the day of or one day before discharge using the Montreal Cognitive Assessment (MoCA). Outcomes included readmission or death at 1, 3 and 12 months, and days at home within 12 months of discharge. Poorer cognitive function was associated with all adverse outcomes. Compared with usual care, DMP was associated with lower odds of 30-day [odds ratio (OR) 0.60, 95% confidence interval 0.40, 0.91] and 90-day (OR 0.53, 95% confidence interval 0.36, 0.77) readmission or death, and with 19 more days at home within 12 months, independent of HF therapy. The effect sizes of these associations were greater for patients with diminished cognition than those with normal cognition (interaction P = 0.036), and might have been more pronounced among those with mild CI compared with those with more severe CI (MoCA score 17-22; OR 0.42, 95% confidence interval 0.21, 0.87) at 30 days (OR 0.31, 95% confidence interval 0.16, 0.60 at 90 days). Patients with normal cognition had fewer events, irrespective of DMP.

CONCLUSIONS

Cognitive function may determine how HF patients respond to a DMP. Cognitive screening before implementation of a DMP may allow personalized plans for patients with different levels of cognitive function.

The Relationship Between Body Awareness and Self-care in Patients With Heart Failure: Moderating Effect of Age

BACKGROUND

Recognizing changing symptoms is challenging for patients with heart failure (HF), especially older patients. Body awareness involves an attentional focus on and awareness of internal bodily changes. Patients with poor body awareness are unlikely to recognize subtle bodily changes, which may result in improper self-care. Despite the potential benefits of body awareness, its contribution to HF management has not been examined.

AIMS

The aims of this study were to examine the relationship between body awareness and self-care in patients with HF and explore whether this relationship varies by age.

METHODS

Patients (N = 136) completed the Body Awareness Questionnaire and 2 scales of the Self-care of HF Index (maintenance and management). Linear regression models were constructed to explore the relationship between body awareness and self-care after controlling for covariates. The moderation effect of age on the relationship between body awareness and self-care was examined using the PROCESS macro.

RESULTS

Body awareness was associated with self-care maintenance (unstandardized coefficient = 0.19; 95% confidence interval, 0.05-0.34) but not management. When the interaction effect of body awareness and age was entered in the regression model, neither self-care maintenance nor management was related to this interaction term.

CONCLUSION

We found that body awareness is conducive to self-care maintenance but not self-care management in patients with HF, and the relationship between body awareness and self-care did not vary by age. Our findings suggest that relying on internal body sensations may be insufficient to facilitate self-care management. Thus, other strategies along with the strategies to enhance body awareness are necessary to improve the full process of self-care in HF patients.

Cognitive deficit, physical frailty, hospitalization and emergency department visits in later life

OBJECTIVES

To examine the added effect of having both cognitive deficit and physical frailty, compared to having either one only, on hospitalization and emergency department (ED) visits.

METHODS

Data from a population-based study of 3,157 community-dwelling older (≥60 years) Chinese adults in the U.S. were used. Cognitive deficit was measured by the Mini-Mental State Examination (i.e. education-adjusted score: 16 [illiterate], 19 [primary school], and 23 [≥middle school]). Physical frailty was identified using the Short Performance Physical Battery (0-6 out of 15). The numbers of hospitalizations and ED visits in the previous two years were self-reported.

RESULTS

In this sample, 12.63% had cognitive deficit alone, 5.95% had physical frailty alone, and 4.26% had both. Compared with participants having neither cognitive deficit nor physical frailty, those having physical frailty alone were 1.5 times as likely to have hospitalizations (Rate Ratio [RR] = 1.52 [1.07, 2.16], p = 0.02) and ED visits (RR = 1.52 [1.07, 2.15], p = 0.02). Having cognitive deficit alone was not significantly related to either outcome. However, having cognitive deficit with existing physical frailty increased the likelihood of both hospitalization (RR = 2.00 [1.36, 2.96], p < 0.001) and ED visits (RR = 2.04 [1.37, 3.03], p < 0.001) to a greater extent than having physical frailty alone.

CONCLUSION

Having cognitive deficit alone was not significantly related to the likelihood of hospitalizations or ED visits, however having cognitive deficit with existing physical frailty increased the likelihood of both outcomes to a greater degree than having physical frailty alone. This suggests cognitive deficit and physical frailty have synergistic effects on hospitalizations and ED visits.

Self-care status in patients with heart failure: Systematic review and meta-analysis

Aim

To systematically review the status of self‐care in patients with heart failure through the Self‐Care of Heart Failure Index scale.

Design

A systematic review and meta‐analysis.

Methods

Following national and international databases were searched to retrieve eligible studies: PubMed, Web of Science, Embase, Google Scholar, Scientific Information Database and Magiran. The studies were screened and selected by two researchers. Data analysed through the random‐effects model, and the I² index was used to assess heterogeneity. Stata software version 12.0 was used for analysis. The PRISMA statement was used to report systematic review and meta‐analysis.

Results

Of the 5,953 articles initially identified, 39 studies were included. The average score was estimated at 58.16 (CI: 54.39–61.94) for self‐care maintenance, 53.11 (CI: 49.17–57.05) for self‐care management and 58.66 (CI: 54.32–63.00) for self‐care confidence. Despite the high heterogeneity of the studies, the results indicated that self‐care practice is inadequate in all the three dimensions of self‐care (maintenance, management and confidence).

Effects of Depression on Heart Failure Self-Care

BACKGROUND

Depression has been identified as a barrier to effective heart failure self-care, but recent studies suggest that the relationship between depression and self-care is more complex than was previously believed. This study was designed to clarify the relationship between depression and self-care in hospitalized patients with HF.

METHODS AND RESULTS

During hospitalization with a confirmed clinical diagnosis of HF, 400 patients completed a structured interview to diagnose Diagnostic and Statistical Manual, 5th edition (DSM-5) depressive disorders, the Patient Health Questionnaire (PHQ-9) depression questionnaire, the Self-Care of Heart Failure Index (SCHFI), and several psychosocial questionnaires. Multivariable models were fitted to each SCHFI scale; separate models were run with DSM-5 disorders and PHQ-9 depression scores. Higher PHQ-9 depression scores were independently associated with lower (worse) scores on the SCHFI Maintenance (P < .05), Management (P < .01), and Confidence (P < .01) scales. No independent associations with DSM-5 depressive disorders were detected. Measures of perceived stress, anxiety, and low perceived social support were also significantly associated with poor HF self-care.

CONCLUSIONS

Patients with a combination of psychosocial problems, including symptoms of depression, stress, anxiety, and inadequate social support, may be more likely than other patients to display difficulties with HF self-care that can increase their risk for hospitalization. Research is needed on "broad-spectrum" psychosocial interventions for patients with HF self-care deficits.

Long-Term Prognostic Value of Cognitive Impairment on Top of Frailty in Older Adults after Acute Coronary Syndrome

Frailty is a marker of poor prognosis in older adults after acute coronary syndrome. We investigated whether cognitive impairment provides additional prognostic information. The study population consisted of a prospective cohort of 342 older (>65 years) adult survivors after acute coronary syndrome. Frailty (Fried score) and cognitive function (Pfeiffer's Short Portable Mental Status Questionnaire-SPMSQ) were assessed at discharge. The endpoints were mortality or acute myocardial infarction at 8.7-year median follow-up. Patient distribution according to SPMSQ results was: no cognitive impairment (SPMSQ = 0 errors; n = 248, 73%), mild impairment (SPMSQ = 1-2 errors; n = 52, 15%), and moderate to severe impairment (SPMSQ ≥3 errors; n = 42, 12%). A total of 245 (72%) patients died or had an acute myocardial infarction, and 216 (63%) patients died. After adjustment for clinical data, comorbidities, and Fried score, the SPMSQ added prognostic value for death or myocardial infarction (per number of errors; HR = 1.11, 95%, CI 1.04-1.19, p = 0.002) and death (HR = 1.11, 95% 1.03-1.20, p = 0.007). An SPMSQ with ≥3 errors identified the highest risk subgroup. Geriatric conditions (SPSMQ and Fried score) explained 19% and 43% of the overall chi-square of the models for predicting death or myocardial infarction and death, respectively. Geriatric assessment after acute coronary syndrome should include both frailty and cognitive function. This is particularly important given that cognitive impairment without dementia can be subclinical and thus remain undetected.

Impact of Instrumental Activities of Daily Living Limitations on Hospital Readmission: an Observational Study Using Machine Learning

BACKGROUND

Limitations in instrumental activities of daily living (IADL) hinder a person's ability to live independently in the community and self-manage their conditions, but its impact on hospital readmission has not been firmly established.

OBJECTIVE

To test the importance of IADL dependency as a predictor of 30-day readmissions and quantify its impact relative to other morbidities.

DESIGN

A retrospective cohort study of the population-based Health and Retirement Study linked to Medicare claims data. Random forest was used to rank each predictor variable in terms of its ability to predict readmission. Classification and regression tree (CART) was used to identify complex multimorbidity combinations associated with high or low risk of readmission. Generalized linear regression was used to estimate the adjusted relative risk of readmission for IADL limitations.

SUBJECTS

Hospitalizations of adults age 65 and older (n = 20,007), from 6617 unique subjects.

MAIN MEASURES

The main outcome was 30-day all-cause unplanned readmission. The main predictor of interest was self-reported IADL limitation. Other key predictors were self-reported complex multimorbidity including chronic diseases, geriatric syndromes, and activities of daily living (ADL) limitations, along with demographic, socioeconomic, and behavioral factors.

KEY RESULTS

The overall 30-day readmission rate in the study was 16.4%. Random forest analysis ranked ADLs and IADL limitations as the two most important predictors of 30-day readmission. CART identified hospitalizations of patients with IADL limitations and diabetes as a subgroup at the highest risk of readmission (26% readmitted). Multivariable regression analyses showed that ADL limitations were associated with 1.17 (1.06-1.29) times higher risk of readmission even after adjusting for other patient covariates. Risk prediction was modest though for even the best model (AUC = 0.612).

CONCLUSIONS

IADL limitations are key predictors of 30-day readmission as demonstrated using several machine learning methods. Routine assessment of functional abilities in hospital settings could help identify those most at risk.

Heart Failure Self-care Associated With Brain Injury in Executive Control Regions

BACKGROUND

Inadequate self-care is linked to poor health outcomes in heart failure (HF). Self-care depends on decision-making abilities, but links between self-care and brain injury to executive decision-making regulatory areas (prefrontal cortices) are unclear.

OBJECTIVE

We investigated the relationships between HF self-care and status of prefrontal cortices.

METHODS

Magnetic resonance imaging-based diffusion tensor imaging was performed in 21 patients with HF (age, 53.8 ± 7.9 years; 15 men; left ventricular ejection fraction, 25.1% ± 6.1%), and self-care and executive function were measured with the Self-care of Heart Failure Index (SCHFI) and Trail Making Test B. Using diffusion tensor imaging data, mean diffusivity (MD) maps were calculated and region-of-interest analyses were performed on the left and right prefrontal brain areas. Statistical analyses consisted of partial correlations (covariates, age, and gender).

RESULTS

The mean ± SD SCHFI scores were 70.78 ± 11.37 for maintenance, 70 ± 17.32 for management, and 74.91 ± 15.76 for confidence. The mean ± SD Trail Making Test B score was 90.2 ± 73.3 seconds. The mean ± SD MD values (higher values indicate tissue injury) of the left and right prefrontal cortices were 1.46 ± 0.16 (×10 mm/s) and 1.44 ± 0.14 (×10 mm/s), respectively. Significant negative correlations emerged between prefrontal MD values and SCHFI maintenance (left/right, r = -0.64/-0.70; P < .003) and SCHFI management (r = -0.93/-0.86; P < .003). Significant positive correlations were observed between prefrontal MD values and Trail Making Test B (r = 0.71/0.74; P < .001). A nonsignificant correlation emerged between prefrontal MD values and SCHFI confidence scores.

CONCLUSIONS

Brain tissue integrity in executive function regulatory regions is associated with HF self-care for maintenance and management. The findings indicate that protection and brain injury repair in executive control areas may improve HF self-care.

Distinct Factors Associated With Better Self-care in Heart Failure Patients With and Without Mild Cognitive Impairment

BACKGROUND

A decline in cognition may limit patients' ability to effectively engage in self-care in those with heart failure (HF). However, several studies have shown no difference in self-care between HF patients with and without cognitive impairment. This may indicate that there are more salient factors associated with self-care in HF patients with cognitive impairment compared with those without cognitive impairment.

OBJECTIVE

The aim of this study was to explore which factors are related to self-care based on the presence and absence of mild cognitive impairment (MCI) among patients with HF.

METHODS

Patients with HF were recruited from outpatient settings. The Montreal Cognitive Assessment was used to screen for MCI. Self-care was measured with the Self-care of HF Index v.6.2. Two separate stepwise linear regressions were performed to identify which factors (HF knowledge, perceived control, functional status, multimorbidity, executive function, and social support) predicted self-care in HF patients with and without MCI.

RESULTS

Of the 132 patients in this study, 36 (27.3%) had MCI. Self-care maintenance and management were associated with social support (β = 0.489) and executive function (β = 0.484), respectively, in patients with MCI. Perceived control was associated with both self-care maintenance and management in patients without MCI (βs = 0.404 and 0.262, respectively).

CONCLUSION

We found that social support and executive function were associated with self-care in HF patients with MCI, whereas perceived control was associated with self-care in HF patients with intact cognition. Clinicians should develop tailored interventions to enhance self-care by considering the distinct factors associated with self-care based on the presence or absence of MCI.

Effectiveness of avatar-based technology in patient education for improving chronic disease knowledge and self-care behavior: a systematic review

OBJECTIVE

The objective of the review was to examine the effectiveness of patient education using avatar-based technology on knowledge and self-care behaviors in patients with chronic disease.

INTRODUCTION

Chronic disease is a major global problem. Patients with chronic disease who engage in self-care and self-management of their illnesses have better health outcomes and fewer hospitalizations and complications. Currently, information and communication technologies are used to support self-care and improve health outcomes. Within the body of literature, research into avatar-based technology for patient education is growing rapidly. To date, the evidence has not been systematically reviewed to determine the effectiveness of patient education using avatar-based technology on patients' knowledge and self-care behaviors in chronic disease.

INCLUSION CRITERIA

This review included studies of children and adults who have received avatar-based patient education interventions. The comparator was usual care or other forms of educational programs. The outcomes were knowledge, self-care behavior, self-efficacy, health-related quality of life, readmission and medication adherence. Experimental designs were eligible, including non-randomized controlled trials, and quasi-experimental, prospective and retrospective before and after studies.

METHODS

Seven databases, including MEDLINE, CINAHL, PsycINFO, Cochrane Central Register of Controlled Trials, ProQuest, Web of Science, Scopus and three other trial registries, including the World Health Organization (WHO), ClinicalTrials.gov and Australian New Zealand Clinical Trials Registry, were systematically searched for studies published between January 2005 and March 2017. Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using the standardized critical appraisal instrument from the Joanna Briggs Institute System for the Unified Management Assessment and Review of Information (JBI SUMARI). Data extracted from papers included specific details about the interventions, populations, study methods and outcomes significant to the review question and specific objectives using the standardized data extraction tool from JBI SUMARI. Due to heterogeneity among the included studies, statistical pooling and meta-analysis were not possible. The results were tabulated, and the data narratively synthesized.

RESULTS

Nine publications from eight studies were included in this review (n = 752). Three out of the eight studies were randomized controlled trials and five were non-randomized experimental studies. The overall quality of the included studies was moderate. There was a low risk of bias for the randomized controlled trial studies and moderate risk of bias for the quasi-experimental studies. Four of the eight studies showed that patients who participated in avatar-based education had a statistically significant improvement in knowledge (p < 0.05). Three studies showed improvement in behaviors and self-efficacy. Only three of eight studies examined health-related quality of life and adherence to medication, but the results were not statistically significant (p > 0.05). No studies identified the effectiveness of avatar-based patient education on readmission.

CONCLUSIONS

Avatar-based technology in patient education can have a positive effect on a wide range of healthcare outcomes. The intervention can improve knowledge, self-care behaviors and self-efficacy in patients with chronic diseases. However, there is limited evidence of improvement in health-related quality of life and adherence to medication, and no available research on readmission.

Predictive factors of a prolonged length of stay in a community Nursing-Led unit: A retrospective cohort study

AIMS AND OBJECTIVES

To describe the care provided to patients admitted into a community Nursing-Led inpatient unit and to identify factors predicting a length of stay exceeding an established threshold.

BACKGROUND

Few studies have been conducted to describe the care provided in a Nursing-Led unit. No studies have investigated factors affecting length of stay in these services.

DESIGN

Retrospective cohort study.

METHODS

Consecutive patients admitted to a community Nursing-Led unit between 2009-2015 were enrolled. Sociodemographic, medical and nursing care (diagnoses and activities) variables were collected from electronic health records. Descriptive analysis and a backward stepwise logistic regression model were applied. The study followed the STROBE guidelines.

RESULTS

The study enrolled 904 patients (mean age: 77.7 years). The most frequent nursing diagnoses were bathing self-care deficit and impaired physical mobility. The nursing activities most provided were enteral medication administration and vital signs measurement. Approximately 37% of the patients had a length of stay longer than the established threshold. Nine covariates, including being discharged to home, having an impaired memory nursing diagnosis or being treated for advanced wound care, were found to be independent predictors of prolonged length of stay. Variables related to medical conditions did not affect the length-of-stay threshold.

CONCLUSIONS

The length of stay in the community Nursing-Led unit was mainly predicted by conditions related to sociodemographic factors, nursing complexity and functional status. This result confirms that the medical and nursing needs of a community Nursing-Led unit population substantively differ from those of hospitalised acute patients.

RELEVANCE TO CLINICAL PRACTICE

The nursing complexity and related nursing care to be provided may be adopted as a criterion to establish the appropriate length of stay in the community Nursing-Led unit for each individual patient.

The Montreal Cognitive Assessment in Veteran Postacute Care: Implications of Cut Scores

BACKGROUND

The Montreal Cognitive Assessment (MoCA) is often used for cognitive screening across health care settings, especially in rehabilitation centers, where assessment and treatment of cognitive function is considered key for successful multidisciplinary treatment. Although the original MoCA validation study suggested a cut score of <26 to identify cognitive impairment, recent studies have suggested that lower cut scores should be applied.

OBJECTIVES

To examine the percentage of positive screens for cognitive impairment using the MoCA in a veteran postacute care (PAC) rehabilitation setting and to identify the most accurate MoCA cut score based on criterion neuropsychological measures.

METHODS

We obtained data from 81 veterans with diverse medical diagnoses who had completed the MoCA during their admission to a PAC unit. A convenience subsample of 50 veterans had also completed four criterion neuropsychological measures.

RESULTS

Depending on the cut score used, the percentage of individuals classified as impaired based on MoCA performance varied widely, ranging from 6.2% to 92.6%. When predicting performance using a more comprehensive battery of criterion neuropsychological tests, we identified <22 as the most accurate MoCA cut score to identify a clinically relevant level of impairment and <24 to identify milder cognitive impairment.

CONCLUSIONS

Our findings suggest that a MoCA cut score of <26 carries a risk of misdiagnosis of cognitive impairment, and scores in the range of <22 to <24 are more reliable for identifying cognitive impairment.

Determining the Optimal Cognitive Screening Tool in Older People With Diabetes

Background: Self-care is an important perspective to aging and transitional states in diabetes management. Population studies have shown that lower cognitive function is associated with worse self-care abilities. Several guidelines have emphasized the importance of assessing cognitive function in older people with diabetes and tailoring treatment plan accordingly. Those guidelines do not specify which tools are the most appropriate for this population. One approach to delineate which tools should be used is to assess which tools best correlate with self-care capacity. Objective: To assess which cognitive assessment tools best correlate with self-care capacity in older people with type 2 diabetes. Methods: Cross-sectional study, conducted amongst individuals with diabetes over the age of 60. The association between self-care capacity indices and different cognitive assessment tools was examined. Principal Component self-care constructs were determined and the association between these and the different cognitive assessment tools was examined. Results: A significant association was found between the Principal Component self-care construct and the Montreal Cognitive Assessment and MindstreamsTM scores. In a stepwise regression model including only the Montreal Cognitive Assessment score, a significant association was found between this score and the Principal Component self-care construct. The same was not found in a model that included only the MindstreamsTM scores. Conclusions: The Montreal Cognitive Assessment, previously validated as a brief cognitive screening tool, may be useful as an adjunct to assess the self-care capacity of older individuals with diabetes. Future studies in the clinic are needed to evaluate if using this tool may improve treatment plans.
