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.

Sex Differences in Heart Failure Symptoms and Factors Associated With Heart Failure Symptoms.

BACKGROUND: A majority of patients with heart failure (HF) experience HF symptoms. Some literature suggests sex differences in the status of and also factors associated with HF symptoms. However, information on common HF symptom status and factors associated with HF symptoms in male and female patients is scarce. OBJECTIVES: The aim of this study was to examine HF symptom status and factors associated with HF symptoms in male and female patients with HF. METHODS: Descriptive data on HF symptoms, psychological factors (depressive symptoms and perceived control), sociodemographic factors (age and sex), clinical factors (body mass index, comorbidities, medication, and left ventricular ejection fraction), and a behavioral factor (self-care) were collected in 70 male and 49 female patients with HF. Mann-Whitney U tests, χ tests, and stepwise regression models were used to address the objectives. RESULTS: Fatigue was the most common HF symptom in both sexes, but male patients had less severe HF symptoms, including frequency, severity, and/or distress. In male patients, 2 psychological and 2 clinical factors (comorbidities and use of diuretics) were significantly associated with HF symptoms (adjusted R = 0.669, P < .001), whereas in female patients, only depressive symptoms were significantly associated with HF symptoms (adjusted R = 0.679, P < .001). DISCUSSION: There were sex differences in HF symptoms and the factors associated with HF symptoms. Clinicians and researchers need to recognize and manage psychological factors in both sexes and clinical factors in male patients by using effective interventions to improve HF symptoms.

Poor Oral Health Predicts Higher 10-Year Cardiovascular Risk: A Propensity Score Matching Analysis.

BACKGROUND: Although the association between periodontitis and cardiovascular disease (CVD) has been reported, whether periodontitis and poor oral health behavior influence CVD risk remains unclear. OBJECTIVE: The aim of this study was to examine whether periodontal disease and poor oral health behavior predict 10-year general CVD risk using the Framingham Risk Score. METHODS: Patients older than 30 years with no CVD history (n = 8370) were selected using cross-sectional study data from the Korean National Health and Nutrition Examination Survey in 2013 and 2014. To reduce selection bias in this population-based study, propensity score matching analysis was used with SPSS and R programs to compare CVD risk. RESULTS: Overall, 39.2% of the study population (n = 3277) had a global CVD risk of  10% or greater. In the low- and at-risk groups, 20.7% and 45.3% of patients, respectively, were diagnosed with periodontal disease by a dentist. Moreover, 43.2% and 62.8% of the low- and at-risk group patients, respectively, brushed teeth less than 3 times a day. After 1:1 propensity score matching of the low-risk (n = 1135) and at-risk (n = 1135) groups, bivariate analyses showed that a diagnosis of periodontal disease and less frequent toothbrushing were associated with a higher CVD risk (P < .001). Logistic regression analysis also showed that patients having periodontal disease and who brushed teeth less frequently were 1.38 and 1.33 times, respectively, more likely to be at risk of CVD (P < .001). CONCLUSION: Education on periodontitis management and oral hygiene behavior should be included, when strategies for public risk reduction of CVD are developed.

Exploring Research Topics and Trends in Nursing-related Communication in Intensive Care Units Using Social Network Analysis.

This study used social network analysis to identify the main research topics and trends in nursing-related communication in intensive care units. Keywords from January 1967 to June 2016 were extracted from PubMed using Medical Subject Headings terms. Social network analysis was performed using Gephi software. Research publications and newly emerging topics in nursing-related communication in intensive care units were classified into five chronological phases. After the weighting was adjusted, the top five keyword searches were "conflict," "length of stay," "nursing continuing education," "family," and "nurses." During the most recent phase, research topics included "critical care nursing," "patient handoff," and "quality improvement." The keywords of the top three groups among the 10 groups identified were related to "neonatal nursing and practice guideline," "infant or pediatric and terminal care," and "family, aged, and nurse-patient relations," respectively. This study can promote a systematic understanding of communication in intensive care units by identifying topic networks. Future studies are needed to conduct large prospective cohort studies and randomized controlled trials to verify the effects of patient-centered communication in intensive care units on patient outcomes, such as length of hospital stay and mortality.

Long-term effects of nurse-led individualized education on middle-aged patients with acute coronary synrome: a quasi-experimental study.

BACKGROUND: This study examined the long-term effects of nurse-led, individualized education on self-efficacy, self-care compliance, and health-related quality of life (HRQoL) in middle-aged patients with new-onset acute coronary syndrome. METHODS: A quasi-experimental pretest-posttest design was used in the study. A cardiovascular nurse provided individualized education to the intervention group (n = 32), and self-efficacy, self-care compliance, and HRQoL at baseline and 3 and 12 months after discharge were compared to those of a control group (n = 30). Patients were recruited from a cardiovascular care unit at a university hospital between 2012 and 2013. Repeated measures analysis of variance was used to compare time-related changes. RESULTS: There was no significant difference in self-efficacy between the 2 groups over a fixed period (F = 3.47, p = 0.067) and showed no interaction between the 2 groups (F = 0.45, p = 0.636). However, significant differences were found in the main and interaction effects between the 2 groups and changes in self-care compliance over the follow-up period differed significantly between the 2 groups (F = 28.72, p < 0.001). Changes in mental HRQoL over the follow-up period differed significantly between the 2 groups (F = 33.34, p < 0.001) and significant interaction effect (F = 4.40, p = 0.040). CONCLUSIONS: Structured nurse-led education should be provided to middle-aged patients with new-onset acute coronary syndrome, as part of routine predischarge education, to increase self-care compliance and mental HRQoL and prevent secondary adverse events. TRIAL REGISTRATION: Trial registration number (TRN) is KCT0002454. The study was registered retrospectively with registration date July 9, 2017.

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

Introduction: In order to promote self-care maintenance behavior in patients with heart failure (HF), it is necessary to identify the direct and indirect effects of major latent variables. Objective: This study aimed to identify structural relationships between different domains of cognitive function, depression and self-care confidence, and self-care maintenance. Methods: This descriptive study involved a secondary analysis using data of 201 patients with HF from two observational studies in three hospitals in Korea. The structural equation model using AMOS version 24.0 was constructed to assess the relationships among the variables. The Seoul Neuropsychological Screening Battery was used to assess global cognition, immediate/delayed memory, and executive function, and the Self-Care of HF Index v.6.2. was used for self-care confidence and maintenance. Results: Self-care maintenance was affected by memory function with a significant direct effect (ß=.43, p = .006), as well as self-care confidence (ß=.70, p < .001). Memory function and global function indirectly affected self-care maintenance through self-care confidence (ß = -.37, p = .002; ß = .14, p = .030). Depressive symptoms also had an indirect effect through self-care confidence on self-care maintenance (ß = -.21, p = .005). Conclusion: This study confirmed that it is important to increase self-care confidence through supportive care and to maintain memory function for maintaining self-care in the chronic course of HF patients. In particular, this study suggests that it is necessary to perform periodic memory check-ups for chronic HF patients on an outpatient basis, and counseling and education are needed to improve memory and increase confidence in self-care.

The Relationship between Compassion Satisfaction and Fatigue with Shift Nurses' Patient Safety-Related Activities.

Background: We examined the relationships of compassion satisfaction and fatigue among shift nurses on nursing engagement activities related to patient safety with the aim of improving shift nurses' physical and psychological aspects in order to use the findings as a basis to enhance nurses' engagement in activities related to patient safety. Methods: The data collection period for this cross-sectional study was from Nov 21, 2019, to Jan 3, 2020. A convenience sample of 280 shift nurses who were working for more than six months at three tertiary hospitals in Korea was used. Collected data comprised general and job-related characteristics of subjects, compassion satisfaction, compassion fatigue, and patient safety nursing activities. SPSS was used for statistical analysis, and multiple regression analysis was used to examine the relationship between shift nurses' compassion satisfaction, compassion fatigue, and patient safety nursing activities. Results: Compassion satisfaction had the greatest impact on engagement in nursing activities related to patient safety (ß= .32, P<.001), followed by compassion fatigue. Higher compassion satisfaction and lower compassion fatigue indicates a higher engagement in patient safety-related nursing activities (ß= -.15, P<.008). Conclusion: In order to maximize compassion satisfaction and reduce compassion fatigue among shift nurses, it is important for health policymakers to improve their welfare system and create a supportive environment where negative emotions can be expressed freely and accepted positively.

The Impact of Advance Directive Perspectives on the Completion of Life-Sustaining Treatment Decisions in Patients with Heart Failure: A Prospective Study.

Evidence for non-modifiable and modifiable factors associated with the utilization of advance directives (ADs) in heart failure (HF) is lacking. The purpose of this study was to examine baseline-to-3-month changes in knowledge, attitudes, and benefits/barriers regarding ADs and their impact on the completion of life-sustaining treatment (LST) decisions at 3-month follow-up among patients with HF. Prospective, descriptive data on AD knowledge, attitudes, and benefits/barriers and LSTs were obtained at baseline and 3-month follow-up after outpatient visits. Of 64 patients (age, 68.6 years; male, 60.9%; New York Heart Association (NYHA) classes I/II, 70.3%), 53.1% at baseline and 43.8% at 3-month follow-up completed LST decisions. Advanced age (odds ratio (OR) = 0.91, p = 0.012) was associated with less likelihood of the completion of LST decisions at 3-month follow-up, while higher education (OR = 1.19, p = 0.025) and NYHA class III/IV (OR = 4.81, p = 0.049) were associated with more likelihood. In conclusion, advanced age predicted less likelihood of LST decisions at 3 months, while higher education and more functional impairment predicted more likelihood. These results imply that early AD discussion seems feasible in mild symptomatic HF patients with poor knowledge about ADs, considering the non-modifiable and modifiable factors.

Critical care nurses' communication experiences with patients and families in an intensive care unit: A qualitative study.

This study evaluated the communication experiences of critical care nurses while caring for patients in an intensive care unit setting. We have collected qualitative data from 16 critical care nurses working in the intensive care unit of a tertiary hospital in Seoul, Korea, through two focus-group discussions and four in-depth individual interviews. All interviews were recorded and transcribed verbatim, and data were analyzed using the Colaizzi's method. Three themes of nurses' communication experiences were identified: facing unexpected communication difficulties, learning through trial and error, and recognizing communication experiences as being essential for care. Nurses recognized that communication is essential for quality care. Our findings indicate that critical care nurses should continuously aim to improve their existing skills regarding communication with patients and their care givers and acquire new communication skills to aid patient care.

Exploring Advance Directive Perspectives and Associations with Preferences for End-of-Life Life-Sustaining Treatments among Patients with Implantable Cardioverter-Defibrillators.

Deactivation of an implantable cardioverter-defibrillator (ICD) is a critical issue in the advance care planning (ACP) of ICD recipients; however, related perspectives have rarely been explored. Thus, this study aimed to provide an initial investigation of ICD recipients' perceived susceptibility and barriers/benefits regarding ACP and/or advance directives (ADs), and associations of these modifiable factors with preferences for end-of-life life-sustaining treatments (LSTs) (cardiopulmonary resuscitation (CPR), ventilator support, hemodialysis, and hospice care). Using a descriptive correlational design, 48 ICD recipients (age, 50.1 years; male, 85.4%) completed survey questionnaires. "No burden on family" was the most highly valued (59.1%), followed by "comfortable death" (20.4%), and both (11.4%). LST preference was 43.8% for ventilator support, 45.8% for both hemodialysis and hospice care, and 54.2% for CPR. Perceived susceptibility to having unexpected end-of-life experiences increased the likelihood of preference for aggressive LSTs, with preferences increasing by 15% for CPR, 17% for ventilator support, and 23% for hemodialysis. A non-modifiable factor, older age, was the only predictor of increased preference for hospice care (odds ratio = 1.09, p = 0.016). Among the modifiable factors, a higher perceived susceptibility increased the likelihood of aggressive LST preferences. The findings imply that to facilitate informed decisions for LSTs, early ACP discussion could be helpful and enhance these modifiable factors.

Do advance directive attitudes and perceived susceptibility and end-of-life life-sustaining treatment preferences between patients with heart failure and cancer differ?

There is limited evidence on the relationships of preference for end-of-life life-sustaining treatments [LSTs] and diagnostic contexts like heart failure [HF] or cancer, and patient attitudes toward and perceived susceptibility to use advance directives [ADs]. Thus, this study aimed to compare attitudes and perceived susceptibility between HF patients and community-dwelling patients with cancer, and examine the associations of these variables with their preference for each LST (cardiopulmonary resuscitation [CPR], ventilation support, hemodialysis, and hospice care). Secondary data were obtained from 36 outpatients with HF (mean age, 65.44 years; male, 69.4%) and 107 cancer patients (mean age, 67.39 years; male, 32.7%). More patients with HF preferred CPR than cancer patients (41.7% and 15.9%, χ2 = 8.88, P = 0.003). Attitudes and perceived susceptibility were similar between the two diagnostic cohorts. HF patients and those with more positive attitudes had greater odds of preferring CPR (odds ratio [OR] = 3.02, confidence interval [CI] = 1.19, 7.70) and hospice care (OR = 1.14, CI = 1.06, 1.23), respectively. HF diagnosis and AD attitudes increased the preference for CPR and hospice care, respectively. This suggests that it is important to gain positive attitudes toward ADs and consider diagnostic context to facilitate informed decision-making for LSTs.

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.

Triage accuracy and causes of mistriage using the Korean Triage and Acuity Scale.

PURPOSE: To identify emergency department triage accuracy using the Korean Triage and Acuity Scale (KTAS) and evaluate the causes of mistriage. METHODS: This cross-sectional retrospective study was based on 1267 systematically selected records of adult patients admitted to two emergency departments between October 2016 and September 2017. Twenty-four variables were assessed, including chief complaints, vital signs according to the initial nursing records, and clinical outcomes. Three triage experts, a certified emergency nurse, a KTAS provider and instructor, and a nurse recommended based on excellent emergency department experience and competence determined the true KTAS. Triage accuracy was evaluated by inter-rater agreement between the expert and emergency nurse KTAS scores. The comments of the experts were analyzed to evaluate the cause of triage error. An independent sample t-test was conducted to compare the number of patient visits per hour in terms of the accuracy and inaccuracy of triage. RESULTS: Inter-rater reliability between the emergency nurse and the true KTAS score was weighted kappa = .83 and Pearson's r = .88 (p < .001). Of 1267 records, 186 (14.7%) showed some disagreement (under triage = 131, over triage = 55). Causes of mistriage included: error applying the numerical rating scale (n = 64) and misjudgment of the physical symptoms associated with the chief complaint (n = 47). There was no statistically significant difference in the number of patient visits per hour for accurate and inaccurate triage (t = -0.77, p = .442). CONCLUSION: There was highly agreement between the KTAS scores determined by emergency nurses and those determined by experts. The main cause of mistriage was misapplication of the pain scale to the KTAS algorithm.

Hospital Nurses' Perceived Patient Safety Culture and Adverse Nurse Outcomes in Korea.

BACKGROUND: Hospital nurses are likely to be the first to observe patient safety issues in clinical settings, and thus it is important to include their views on patient safety culture. However, there are few studies addressing the influence of nurses' perceived patient safety culture on adverse nurse outcomes as quality of care. PURPOSE: This study was to identify the relationship between nurses' perceptions of patient safety culture and adverse nurse outcomes in Korea. METHODS: This cross-sectional study was included 299 nurses at two tertiary hospitals. Hierarchical linear regression was conducted to examine the impact of patient safety culture on adverse nurse outcomes among hospital nurses. RESULTS: The mean score of patient safety culture and adverse nurse outcomes were 3.50 out of 5 points and 3.07 out of 4 points respectively. In hierarchical linear regression, hospital work environment, the attitude of supervisor/manager, and hospital climate/culture of patient safety culture predicted adverse nurse outcomes after adjusting for general characteristics. CONCLUSIONS: It is crucial for healthcare facilities to assess or evaluate their current patient safety culture perceptions on a regular basis. Furthermore, provision workshops and staff training on changing behaviors and perceptions regarding patient safety activities can improve nursing performance in clinical settings.

Memory loss and decreased executive function are associated with limited functional capacity in patients with heart failure compared to patients with other medical conditions.

BACKGROUND: There is limited evidence on the degree of cognitive impairment and its association with physical functional capacity among patients with heart failure (HF) in Korea. OBJECTIVES: In this study, we compared cognitive impairment between patients with HF and community-dwelling participants with non-HF medical conditions (medical participants) and its association with physical functional capacity. METHODS: We conducted a cross-sectional comparative study and assessed the neuropsychological cognitive status (Seoul Neuropsychological Screening Battery) and physical functional capacity (Duke Activity Status Index) of patients with HF and medical participants using face-to-face interviews. RESULTS: One hundred and eighteen patients with HF (age, 65.45 ± 9.38 years; men, 57.6%; left ventricular ejection fraction, 34.93 ± 8.72%) and 83 medical participants (age, 66.02 ± 8.28 years; men, 47.0%) were included. Using seventh-percentile medical participant Z-scores as cutoffs, memory and executive function were worse in patients with HF than in medical participants: immediate (35.0% vs. 6.0%) and delayed recall memory (34.5% vs. 8.4%), and executive function (28.6% vs. 6.0%). Independent of age, sex, education, comorbidity, and HF status, executive function was a significant predictor of physical functional capacity (b = 1.82, p = .021). CONCLUSIONS: More patients with HF had impaired memory and executive function, which were associated with their physical functional capacities.

Concomitant diastolic dysfunction further interferes with cognitive performance in moderate to severe systolic heart failure.

BACKGROUND: Studies of the relevance of cardiac functional markers to cognitive performance in heart failure (HF) have primarily focused on systolic markers. In this study, we examine whether concomitant diastolic dysfunction further interferes with cognitive performance in memory, attention, and executive function in patients with HF. METHODS AND RESULTS: In this cross-sectional correlational study, 82 patients completed face-to-face interviews for neuropsychological testing for cognitive evaluation. Echocardiographic data were obtained from a review of medical records. Mild to moderate (ejection fraction [EF] ≥ 30%) and severe (EF < 30%) systolic dysfunction were present in 55 (67.1%) and 27 (32.9%) patients, respectively, while 21 (26.3%) had diastolic dysfunction (E/e' > 15). Those patients who had severe systolic dysfunction had significantly lower attention scores (Digit Span Test [DST] backward, t = 2.62, p = 0.011), while those with concomitant severe diastolic dysfunction had significantly lower verbal fluency (t = 2.84, p = 0.006) and executive function (Korean-Trail Making Test Part B) (t = -2.14, p = 0.036) scores than those without severe diastolic dysfunction. After controlling for age and education, systolic patients with HF with concomitant severe diastolic dysfunction had worse cognitive performance in verbal fluency than those without severe diastolic dysfunction (F = 4.33, p = 0.041, partial eta = 0.057). Concomitant moderate to severe systolic and severe diastolic dysfunction further reduced verbal fluency (F = 8.42, p = 0.005, partial eta = 0.106). CONCLUSIONS: Cognitive performance, particularly executive function, was worse in patients with HF with systolic dysfunction when diastolic dysfunction was concomitantly present. Routine monitoring of and surveillance for diastolic dysfunction and cognitive screening are warranted in the management of patients with HF.

[Development and Effects of a Heart Health Diary for Self-Care Enhancement of Patients with Heart Failure].

PURPOSE: The purpose of this study was to develop a heart health diary to promote self-care ability among patients with heart failure (HF), and to identify the diary's effect on self-care adherence, self-efficacy, and physical activity. METHODS: A randomized control-group pretestposttest design was adopted using block randomization. A calender-typed health diary was developed and it included a self-care checklist and education information on HF management. The experimental group were given guided counseling and education for 8 weeks and wrote a daily health diary during that period. Data were collected from the outpatient department of a tertiary medical center from February to April 2016. To verify the hypotheses, data for the experimental group (n=28) and control group (n=33) were analysed using the independent t-test with SPSS/WIN 21.0. RESULTS: At the end of 8 weeks the experimental group had significantly higher scores for self-care adherence (t=-2.48, p=.016) and exercise related self-efficacy (t=-3.44, p=.001) compared to the control group. CONCLUSION: The findings show that the application of a patient-directed heart health diary is an effective nursing intervention for improving HF patients' self-care adherence and exercise self-efficacy. Strategies to promote dietary self-efficacy are necessary along with further studies including repeated research with an increasing intervention period. Healthcare providers need to encourage the utilization of a health diary for HF patients as a tool for evaluation and for implementation that leads to self-care.

Cognitive Function and Self-Care in Patients with Chronic Heart Failure.

BACKGROUND AND OBJECTIVES: This study examined the association of cognitive function with self-care and major adverse cardiac events (MACE) among heart failure (HF) patients. SUBJECTS AND METHODS: In this prospective study, 86 outpatients with HF completed face-to-face interviews including neuropsychological testing to evaluate cognitive function and the use of the Self-Care of Heart Failure Index to measure self-care. Functional status was assessed with the New York Heart Association (NYHA) classification. Follow-up data on MACE were obtained at 24 months after enrollment. RESULTS: Compared with the Korean norm values, more than half of the HF patients had cognitive deficits in global function (33.0%), immediate recall (65.1%), delayed recall memory (65.1%), and executive function (60.5%). Patients with symptomatic HF (≥NYHA class II) had the higher risk for substantially poor cognitive function in all areas of cognitive function than asymptomatic HF patients (NYHA class I, p<0.05). Most patients demonstrated poor self-care adequacy in maintenance (84.9%), management of symptoms (100%), and confidence (86.0%). After adjustment for age and gender, memory function was significantly associated with self-care confidence (odds ratio 1.41, 95% confidence interval 1.03-1.92, p=0.033). No relationship was found between cognition and self-care maintenance. There were 19 MACE's during the 24-month follow-up. Patients without MACE had a significantly higher global cognitive function (p=0.024), while no cognitive domains were significant predictors of MACE when adjusted for age and gender. CONCLUSION: HF patients with memory loss have poorer self-care confidence. Studies are warranted to examine the functional implication of cognitive deficits and adverse outcomes in a larger sample.
