Factors Related to Patients' Self-care and Self-care Confidence in Korean Patients With Heart Failure and Their Caregivers: A Cross-sectional, Correlational Study.

BACKGROUND: The relationships of patient factors and caregiver contribution to patients' self-care to different types of self-care have been rarely examined in Korean patients with heart failure. OBJECTIVE: The aim of this study was to examine patient (ie, age, depressive symptoms, and self-care confidence) and caregiver (ie, caregiver contribution to self-care maintenance and self-care management, and caregiver confidence in contributing to self-care) factors related to different types of self-care (ie, self-care maintenance, symptom perception, and self-care management) and self-care confidence in Korean patients with heart failure. METHODS: In this cross-sectional, correlational study, data from 41 pairs of patients (mean age, 68.0 years) and caregivers (mean age, 54.1 years) were collected and analyzed using multiple regression. RESULTS: Higher levels of self-care confidence in patients were related to higher levels of self-care maintenance in patients. Higher levels of self-care confidence in patients were related to higher levels of symptom perception. Higher levels of self-care confidence in patients and caregiver contribution to self-care maintenance were related to higher levels of self-care management. Less severe depressive symptoms in patients and higher levels of caregiver confidence in contributing to self-care were related to higher levels of self-care confidence. CONCLUSION: Different patient and caregiver factors were related to different types of self-care and self-care confidence in Korean patients, but patients' self-care confidence was related to all types of self-care. Clinicians and researchers need to develop and deliver effective interventions to both patients and their caregivers to improve patients' self-care confidence and, in turn, self-care, considering different factors associated with each type of self-care.

Experiences of and factors associated with dietary sodium adherence in heart failure from patients' and their caregivers' perspectives: A qualitative study.

This study explored experiences of dietary sodium adherence among patients with heart failure and their caregivers. Qualitative data were collected from 22 patients and 18 caregivers using an interview guide and were analyzed using content analysis. Four themes were (1) lack of adherence to low-sodium diet, (2) several barriers to dietary sodium adherence, (3) a few facilitators of dietary sodium adherence, and (4) distorted perceptions of dietary education from healthcare providers. The majority of patients had poor dietary sodium adherence. Distorted perceptions, insufficient knowledge, disadvantages of dietary sodium adherence, and lack of family support were barriers to dietary sodium adherence, and family support was a facilitator. The majority of patients received dietary education from their healthcare providers but had little knowledge about the detailed content and the connection to heart failure management. More effective interventions reflecting patients' and caregivers' dietary experiences need to be developed and delivered.

Effect of physical and psychocognitive function and perceived health status on 12-month adverse cardiac events among implantable cardioverter-defibrillator recipients.

BACKGROUND: Post-implant recovery in patients with implantable cardioverter-defibrillators (ICDs) is often compromised because of reduced physical and psycho-cognitive function and poor health perception, leading to short event-free survival. OBJECTIVES: To examine the effects of psychocognitive function, health perception, and ICD-related factors on 12-month cardiac events among ICD patients. METHODS: Using a prospective study design, ICD patients underwent baseline assessment and were followed for 12 months to assess cardiac events. RESULTS: Cardiac events occurred in 14 patients (18.9%) (N = 74: age, 58 years; primary ICDs, 45.9%). Time after ICD implant (odds ratio [OR] = 1.002; p = .028) and executive function (OR = 1.021; p = .027) were significant predictors of 12-month cardiac events, while other physical and psychological indices were not. CONCLUSIONS: Reduced executive function and longer time after implant predicted the events. Healthcare professionals need to assess executive function and provide treatment and support to improve executive function.

Modifiable Factors Associated with the Completion of Advance Treatment Directives in Hematologic Malignancy: A Patient-Caregiver Dyadic Analysis.

Objective: The completion rates of advance treatment preferences in patients with hematologic malignancies are low. To improve these rates, the modifiable factors associated with completion need to be determined. This study aimed to examine the associations of patient attitudes toward, and knowledge about, advance directives (ADs) with the patient-caregiver dyadic completion of advance treatment directive surveys. Methods: Using a nonexperimental correlational design, 44 patient-caregiver dyads completed the questionnaires, including a Korean-Advance Directive model. Cohen's kappa coefficient and multiple logistic regression analyses examined the extent of dyadic agreement and patient factors for the dyadic completion of the advance treatment directive survey, respectively. Results: A minor group of patients (4.5%-11.4%) and caregivers (11.4%-18.2%) preferred aggressive end-of-life treatments, whereas more patients (47.7%) and caregivers (68.2%) supported hospice care. The only significant patient-caregiver dyadic concordance on treatment directives was for chemotherapy with a moderately high agreement (kappa = 0.60: 95% CI: 2.51-3.73). One score increase in AD knowledge and having a history of hematopoietic stem cell transplant (HSCT) increased the likelihood of dyadic completion of the treatment directive survey by 43% (p = 0.039) and 917% (p = 0.047), respectively. Conclusions: The patient-caregiver dyads in the setting of hematologic malignancy had a moderately high concordance with chemotherapy but were not associated with other treatment options. A higher level of AD knowledge and HSCT were associated with dyadic completion of the AD survey. Educational support is important to increase knowledge regarding ADs through ongoing palliative discussions among hematologic patients and their caregivers.

Correlates of life-support treatment preferences among low-income home-based cancer management recipients.

PURPOSE: To examine the correlates of life-support treatment (LST) preferences from attitudes toward advance directives (ADs), perceived susceptibility, symptom frequency, symptom burden, and global health among low-income community-dwelling cancer management recipients, controlling for age, sex, education, and duration after cancer diagnosis. METHODS: A cross-sectional, correlational study design was used to assess LST preferences and correlates. Data were collected from low-income cancer survivors during nurses' home visits. RESULTS: Survivors who had mostly solid cancer participated (N = 107, mean age = 67.39 ±â€¯11.57 years, 32.7% males). Hospice care was the most desired (66.4%), while aggressive treatments were less preferred: cardiopulmonary resuscitation (15.9%), ventilation support (15.0%), hemodialysis (18.7%), or chemotherapy (12.1%). Higher symptom frequency was associated with a greater likelihood of preferring all aggressive treatments (odds ratios = 1.44-1.75). In addition, longer cancer duration was associated with a greater likelihood of preferring ventilation support; females had a lesser likelihood of preferring hemodialysis and chemotherapy. Higher education was associated with a lesser likelihood of preferring chemotherapy. More positive attitudes (B = 0.15, p = .001) were associated with a greater likelihood of preferring hospice care, and greater symptom burden of pain (B = -0.03, p = .047) was associated with a lesser likelihood. CONCLUSION: Results support the feasibility of incorporating ADs into cancer management among community-dwelling cancer survivors, with consideration of AD attitudes and symptom monitoring. An integration of AD discussion into the home visiting service could be a liaison for the quality and continuity of cancer survivorship care that guides and manages patients' survivorship issues.

The Korean-Advance Directive Model and Factors Associated With Its Completion Among Patients With Hematologic Disorders.

The objective of this pilot study was to examine factors associated with the completion of advance directives (ADs) among patients with hematologic disorders in Korea. Using a descriptive design, patients with largely hematologic malignancies completed the questionnaires, including the Korean-Advance Directive (K-AD) model, which pertains to values, treatment wishes, and proxy appointment. Of 45 patients (aged 48.7 ± 10.7 years, 51.1% men), two-thirds had leukemia (40.0%) and lymphoma (26.7%). "Dying comfortably" was the most frequently selected value (n = 20). Regarding treatment wishes, hospice care was the most desired type (n = 22), whereas aggressive treatments, such as cardiopulmonary resuscitation, were less preferred (n = 3). The patient's spouse was most frequently appointed as a proxy (n = 27). Patients who completed all the 3 components of the K-AD model (51.1%) were less depressed (t = -2.31; P = .028) and more likely to perceive the benefits of the K-AD model (t = 2.07; P = .045), compared with the noncompleters (48.9%). Further, being male (odds ratio [OR], 6.42; P = .031), having higher scores on depressive symptoms (OR, 1.28; P = .016), and perceived barriers (OR, 1.08; P = .040) were associated with lower tendency to complete the K-AD model. These findings support the need for earlier introduction of ADs in hematologic disorders, with consideration of modifiable factors such as depression or barriers to end-of-life care decisions.

A Context-oriented Communication Algorithm for Advance Care Planning: A Model to Assist Palliative Care in Heart Failure.

BACKGROUND: Access to consultation or referral for decisions about advance care planning (ACP) is limited, particularly for nonmalignant models pertinent to palliative care in heart failure (HF). OBJECTIVES: The aim of this study was to solicit professional opinions about the feasibility of using an exemplary context-oriented communication algorithm for ACP discussions. METHODS: Using a panel of expert physicians and nurses in cardiovascular care, a 3-round Delphi study was conducted to evaluate the proposed model. RESULTS: A consensus was determined based on a content validity ratio (CVR) of 0.318 or greater, a critical value for selection of an item scored as important (≥4 on a 5-point Likert scale). A total of 50, 44, and 38 experts in Korea completed each round, respectively. Item evaluation did not differ across rounds (Friedman χ > P = .05), except for timing of the ACP discussion. A lack of consensus was observed on the issue of after HF diagnosis for right timing of the ACP discussion across rounds (CVRs from -0.80 to -0.83); consensus was reached on the expectation of a terminal state (CVRs from 0.60 to 0.78). Content validity ratios were moderately high for Korean advance directive, ranging from 0.59 to 0.91. Experts also reached consensus about each of 5 steps of a communication model-patients' determination of decisional capacity (CVR, 0.72-1.0), awareness (CVR, 0.95-1.0), willingness for advance care planning (CVR, 0.76-0.84), family dynamics (CVR, 0.92-1.0) and patient readiness for advance care planning (CVR, 0.76-0.95). CONCLUSIONS: A context-oriented communication model could be used to facilitate the decision-making process for palliative care and continuity of care in HF.

[Meta-analysis of the research findings concerning functional relationships of explanatory variables to hope].

PURPOSE: The purpose of the study was to meta-analyze the relationships of major concepts, which were made by synthesizing similar explanatory variables into more comprehensive concepts, to hope. METHOD: The relevant researches from Jan 1980 to Dec 2003, performed in adults or adult patients, were collected. Using the SAS program, meta-analysis were done with the input data of the number of subjects, the correlation coefficients provided from most of the studies or a few transformed correlation coefficients from F value. In order to get the analysis to be done in homogeneous status of the data regarding each relationship of each major concept to hope (p>0.05), heterogeneous data were eliminated in repeating Q-test. RESULT: The major variable regarding relationship to self/transcendental being/life (spiritual wellbeing & self esteem) and social support (social support & family support) have very large positive effects on hope (D=1.72, D=1.27). The negative effect of the variable regarding captive state(uncertainty in illness, perceived unhealthiness status, & fatigue) and positive effect of coping (approach coping) on hope are in the level between moderate to large (D=-0.61, D=0.78). All the effects of the major concepts on hope were verified as significant statistically(p=.000). The Fail-Safe numbers showed the significant effects of the three major concepts except coping on hope were reliable. CONCLUSION: The results can be a guide to advance hope theory for nursing.
