Translation, adaptation, and validation of a Chinese version of the Hypertension Self-Care Activity Level effects (H-SCALE) for patients with hypertension.

BACKGROUND: Lifestyle modification is an essential component of prevention and management of hypertension. Existing instruments in Taiwan focus on assessing lifestyle modifications by evaluating medication adherence or confidence in controlling blood pressure. However, other self-care activities, such as diet, physical activity, weight management, smoking, and alcohol consumption are also important. The Hypertension Self-Care Activity Level Effects (H-SCALE) is one such instrument, but there are no similar tools available in Taiwan. AIM: This study aimed to translate the H-SCALE into Chinese and test its validity, and reliability in a sample of adults with hypertension. METHODS: The English version of the 31-item H-SCALE was translated into Chinese using the forward-backward method. The content validity index (CVI) of the translated scale was determined by five experts in hypertension. Item analysis was conducted with a pilot sample of 20 patients with hypertension. Cronbach's α was used to establish the internal consistency reliability for the Chinese version of the H-SCALE (H-SCALE-C). Exploratory factor analysis (EFA) explored the structure of the H-SCALE-C. Additionally, construct validity was examined with confirmatory factor analysis (CFA). Patients with hypertension were recruited by convenience sampling from a cardiovascular outpatient clinic of a medical center in northern Taiwan. A total of 318 patients met the inclusion criteria and participated in factor analysis in the study. RESULTS: Pilot testing of the scale items indicated most patients could not accurately estimate the number of days of alcohol consumption for the previous week. Therefore, three alcohol-related items were removed. The adaptation resulted in a 28-item H-SCALE-C. EFA revealed a 4-factor solution with 13 items that explained 63.93% of the total variance. CFA indicated a good fit for a 4-factor model and construct validity was acceptable. Internal consistency reliability was acceptable (Cronbach's alpha for the four subscales ranged from 0.65 to 0.94). Convergent validity was acceptable, and discriminant validity was significant. CONCLUSIONS: The H-SCALE-C is a valid, reliable tool for promptly assessing life-style activities for patients with hypertension in Taiwan. The instrument is suitable for assisting healthcare providers in evaluating self-care activities, which could be used to facilitate lifestyle modifications for patients with hypertension.

Mediating Effect of Heart Rate Variability on the Relationship Between Anxiety Symptoms and Blood Pressure in Patients with Primary Hypertension.

Patients with hypertension (HTN) are at increased risk of developing cardiovascular disease, which can be reduced with blood pressure (BP) control. Anxiety can contribute to high BP and low heart rate variability (HRV). Although relationships between social support, self-rated health-status (SRHS), anxiety and measures of HRV and BP have been suggested, they have not been clearly established. This cross-sectional correlational study aimed to 1) examine relationships between social support, SRHS, and anxiety; and 2) examine if HRV mediated relationships between anxiety symptoms and BP. Patients with primary HTN were recruited from a cardiovascular outpatient clinic using convenience sampling (N = 300). Data included scale scores for SRHS, social support, and anxiety (Hospital Anxiety and Depression Scale). A handheld limb-lead electrocardiogram monitor measured HRV, using the ratio of low-frequency bands to high-frequency bands; an automatic sphygmomanometer measured systolic and diastolic blood pressure (SBP and DBP, respectively). Path analysis of structural equation models examined relationships between variables; the bootstrap method examined the mediating effects of HRV. Analysis showed scores for SRHS and social support had a direct effect on anxiety scores. Scores for anxiety directly affected HRV and BP. HRV also had a direct effect on BP. Bootstrapping indicated HRV mediated the relationship between anxiety symptoms and BP. The final model indicated SRHS, social support, and anxiety symptoms together explained 80% of SBP and 33% of DBP. These findings suggest HRV could be used to measure the effectiveness of strategies aimed at reducing anxiety and improving control of BP.

[Concept Analysis of Learned Resourcefulness].

Learned resourcefulness is a broad and abstract concept that refers to the ability to use self-observation and self-control to change internal negative feelings, emotions, or thoughts to reduce the adverse effects of stress on emotions and behavior. Excessive stress negatively affects the physical and mental health of individuals, and learned resourcefulness can help alleviate the effects of stress. Nursing measures implemented in a timely manner to enhance patients' self-regulation ability and improve their mental and physical stability are important. In this article, based on the concept analysis method of Walker and Avant (2019), the defining characteristics of learned resourcefulness are summarized as: (1) self-control ability, (2) problem-solving skills, and (3) belief in one's ability to cope effectively with adverse situations. These characteristics are illustrated in case examples, providing empirical reference indicators and introducing the application of nursing research and practice. It is hoped that this article will help nursing colleagues understand learned resourcefulness and provide a reference for clinical assessment and the development of related intervention measures.

Factors influencing self-care among patients with primary hypertension: path analysis of mediating roles of self-efficacy and depressive symptoms.

AIMS: Blood pressure control requires medication adherence and lifestyle modifications. Social cognitive theory suggests social support, psychological adaptation, and self-efficacy can reinforce lifestyle modifications. This study investigated if self-efficacy was a mediator between self-rated health status (SRHS), social support, depressive symptoms, anxiety, and self-care among patients with hypertension. METHOD AND RESULTS: This cross-sectional study recruited patients with primary hypertension by convenience sampling (N = 318) from an outpatient cardiology clinic. Data included participant characteristics and self-report scales for social support, SRHS, anxiety, depressive symptoms, Self-efficacy and self-care diet quality and weight management. We used path analysis to test the hypothesized model. The mean age of participants was 63.91 ± 11.80 years. Mean scale scores for social support and depressive symptoms were 54.23 ± 13.26 and 6.14 ± 3.14, respectively; SRHS was 66.91 ± 13.80, self-efficacy was 34.31 ± 11.62, self-care for diet quality and weight management were 36.50 ± 13.19 and 27.38 ± 8.64, respectively. Bootstrapping demonstrated self-efficacy was the mediator between social support and self-care for diet quality and weight management; depressive symptoms mediated the relationship between social support and self-efficacy. In addition, the variable of depressive symptoms was also a mediator between SRHS and self-efficacy. The final model showed SRHS, social support, depressive symptoms, and self-efficacy explained 28% of self-care. CONCLUSION: Our findings suggest developing theory-based interventions for patients with hypertension that provide education and/or psychological support for increasing patients' self-efficacy and reducing depressive symptoms simultaneously to facilitate their long-term self-care behaviours.

A web-based self-care program to promote healthy lifestyles and control blood pressure in patients with primary hypertension: A randomized controlled trial.

BACKGROUND: Hypertension is a major risk factor for cardiovascular diseases, which contributes to the worldwide mortality rate. Successful blood pressure control requires adherence to medications and lifestyle modifications. However, motivating patients with primary hypertension to change and sustain behaviors long-term is challenging. A web-based self-care program centered on self-efficacy theory could provide feedback for effective control of blood pressure. PURPOSE: To examine the effect of a web-based self-care program for patients with primary hypertension on cardiovascular risk-factors (pulse pressure and lipids), self-efficacy, and self-care behaviors (medication adherence and lifestyle). DESIGN: A two-armed randomized controlled trial with 3-month and 6-month follow-ups. SETTING AND PARTICIPANTS: A total of 222 patients with primary hypertension were recruited between February 2017 and August 2018 at a cardiology clinic of a medical center in Taipei, Taiwan. METHODS: Eligible patients were randomized by permuted block randomization into the intervention group (n = 111) and control group (n = 111). Patients in the intervention group received a 6-month web-based self-care program, based on the theory of self-efficacy, while patients in the control group received usual care. Baseline and outcome measures (3 and 6 months) included self-efficacy, evaluated with the Chinese version of the 6-item Self-Efficacy for Managing Chronic Diseases (SEMC6), self-care, using subscales of the Hypertension Self-Care Activity Level Effects Scale (H-SCALE) for lifestyle and medication adherence, and blood pressure and serum lipid data, collected through web-based self-reports and chart review. Generalized estimating equations evaluated the effects of the intervention. FINDINGS: At baseline, the control group had higher scores on the SEMC6, and lower cholesterol (HDL) compared with the intervention group (t = -2.70, p < 0.05; and t = 1.76, p < 0.05, respectively). Pulse pressure decreased significantly (ß = -20.30, 95% CI -23.76, -16.83), and serum triglycerides and low-density lipoprotein cholesterol levels were significantly lower compared with controls at 6 months (all p < 0.001). At 6 months, the intervention group had significantly higher mean scores for the SEMC6 compared with the control group (ß = 21.84, 95% confidence interval [CI] 19.25, 24.42) and H-SCALE subscale for medication adherence, diet, weight management, and physical activity compared with controls at 6 months (all, p < 0.001). CONCLUSIONS AND CLINICAL RELEVANCE: The greatest benefit of this program was allowing participants to immediately consult with the researchers about self-care issues via the website. Lifestyles vary from person to person; therefore, the individuality of each participant was considered when providing feedback. We provided devising interventions for participants that would increase their confidence in self-care for hypertension and ultimately achieve home blood pressure control. We encourage incorporating this program into standard clinical care for patients with hypertension.

A Web-Based Integrated Management Program for Improving Medication Adherence and Quality of Life, and Reducing Readmission in Patients With Atrial Fibrillation: Randomized Controlled Trial.

BACKGROUND: Atrial fibrillation (AF) is related to a variety of chronic diseases and life-threatening complications. It is estimated that by 2050, there will be 72 million patients with AF in Asia, of which 2.9 million will have AF-associated stroke. AF has become a major issue for health care systems. OBJECTIVE: We aimed to evaluate the effects of a web-based integrated management program on improving coping strategies, medication adherence, and health-related quality of life (HRQoL) in patients with AF, and to detect the effect on decreasing readmission events. METHODS: The parallel-group, single-blind, prospective randomized controlled trial recruited patients with AF from a medical center in northern Taiwan and divided them randomly into intervention and control groups. Patients in the intervention group received the web-based integrated management program, whereas those in the control group received usual care. The measurement tools included the Brief Coping Orientation to Problems Experienced (COPE) scale, Medication Adherence Rating Scale (MARS), the three-level version of the EuroQoL five-dimension self-report questionnaire (EQ-5D-3L), and readmission events 2 years after initiating the intervention. Data were collected at 4 instances (baseline, 1 month, 3 months, and 6 months after initiating the intervention), and analyzed with generalized estimating equations (GEEs). RESULTS: A total of 231 patients were recruited and allocated into an intervention (n=115) or control (n=116) group. The mean age of participants was 73.08 (SD 11.71) years. Most participants were diagnosed with paroxysmal AF (171/231, 74%), and the most frequent comorbidity was hypertension (162/231, 70.1%). Compared with the control group, the intervention group showed significantly greater improvement in approach coping strategies, medication adherence, and HRQoL at 1, 3, and 6 months (all P<.05). In addition, the intervention group showed significantly fewer readmission events within 2 years (OR 0.406, P=.03), compared with the control group. CONCLUSIONS: The web-based integrated management program can significantly improve patients' coping strategy and medication adherence. Therefore, it can empower patients to maintain disease stability, which is a major factor in improving their HRQoL and reducing readmission events within 2 years.

Government's subsidisation policy and utilisation of smoking cessation treatments: a population-based cross-sectional study in Taiwan.

OBJECTIVES: This study examined the associations between the Second-Generation Cessation Payment Scheme (SCPS) and the use of smoking cessation treatments. Furthermore, these associations were compared between light and heavy smokers in Taiwan. DESIGN: This study had a cross-sectional design. SETTING: Data were obtained from the Taiwan Adult Smoking Behaviour Surveillance System 2010-2011 and 2013-2014; data for each year consisted of a nationally representative sample of adults aged 18 years and older. PARTICIPANTS: Current smokers who had either quit or made a serious attempt to quit smoking were selected for the analysis. PRIMARY OUTCOME MEASURE: The primary outcome measure was the use of a smoking cessation clinic or pharmacy in a twice daily to quit smoking. RESULTS: According to multivariate analysis, the SCPS was positively associated with the combined use of a smoking cessation clinic and a pharmacy (OR=3.947; 95% CI: 1.359 to 11.463) when individual-level predictors (gender, age, education level, marital status, monthly household income, daily cigarette consumption, smoking status and self-reported health) were controlled. Heavy smokers showed a significant increase in the sole use of a pharmacy (OR=1.676; 95% CI: 1.094 to 2.569) and combined use of a smoking cessation clinic and pharmacy (OR=8.984; 95% CI: 1.914 to 42.173) after the SCPS was introduced. In addition, when related factors were controlled, the use of smoking cessation services was more frequent among heavy smokers than light smokers, including any treatment (OR=1.594; 95% CI: 1.308 to 1.942), a smoking cessation clinic (OR=1.539; 95% CI: 1.232 to 1.922), a pharmacy (OR=1.632; 95% CI: 1.157 to 2.302) and the combination of a smoking cessation clinic and pharmacy (OR=4.608; 95% CI: 1.331 to 15.949) . CONCLUSIONS: The SCPS subsidisation policy increased the use of smoking cessation treatments, particularly among heavy smokers.

[Experience of Implementing ABCDEF Bundle Care to Reduce Delirium in a Traumatic Brain Injury Patient].

Patients with traumatic brain injury (TBI) have a high incidence rate of delirium, which leads to poor prognoses. This case study describes a nursing experience of implementing ABCDEF bundle care to reduce delirium in a patient with TBI. The period of nursing care was April 23 to April 30, 2019. A comprehensive assessment of this patient's physical, psychological, familial, social, and spiritual dimensions was conducted via consultation, observation, and physical assessment. The assessment results showed that the patient suffered from acute delirium and cerebral perfusion impairment. In addition, the results showed that the patient's wife suffered from caregiver role strain that was further exacerbated by family difficulties. Multiple, individualized patient-tailored nursing interventions were developed under ABCDEF bundle care to alleviate delirium during the period of nursing care. These interventions included spontaneous awakening trials, spontaneous breathing trials, coordination, delirium assessment, early mobilization, and family engagement. Furthermore, family involvement and interprofessional cooperation with social workers were conducted concurrently to alleviate economic and care burdens and mitigate caregiver role strain in the patient's wife. It is hoped that this nursing care experience helps promote increased attention towards delirium, helps improve early detection of delirium in patients with TBI, and promotes the provision of individualized bundle care that draws on different perspectives in order to achieve holistic health care.

[The Effects of Mobile Health Care on the Physiological Index in Patients With Coronary Artery Disease].

BACKGROUND: Coronary artery disease is associated with unhealthy lifestyles such as smoking, lack of physical activity, and consuming an unhealthy diet. Other risk factors include family history and comorbidities such as hypertension, diabetes, smoking, obesity, and hypercholesterolemia. PURPOSE: This study aims to investigate the effectiveness of mobile health care in improving the physiological index of patients with coronary artery disease. METHODS: This study used an experimental design. Convenience sampling was used to enroll 129 patients with coronary heart disease as participants, who were randomly assigned into the intervention group (n = 64) and control group (n = 65). The intervention group participants received a 12-week mobile health care intervention, while the control group participants received routine care in the outpatient department. The physiological index outcome variables included body mass index (BMI), lipid profile, and blood pressure. Data were analyzed using generalized estimating equation curve analysis. RESULTS: The mean triglyceride (TG) reduction value after the intervention in the experimental group was significantly higher (reduction of 39.27 mg/dl; p < .05) than in the control group. Moreover, mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) reduction values in the experimental group were significantly higher (reductions of 8.32 mmHg and 4.24 mmHg; p < .01) than in the control group. Furthermore, the mean reduction in BMI value in the experimental group was significantly higher (reduction of 0.48 Kg/m2; p < .05) than in the control group. Finally, only the mean reduction in low density lipoprotein (LDL) values was greater (by 1.11 mg/dl) in the experimental group than in the control group. However, this reduction did not reach statistical significance. CONCLUSIONS: Mobile health care has the potential to reduce TG, blood pressure, and BMI in patients with coronary artery disease.

A Web-Based Self-Titration Program to Control Blood Pressure in Patients With Primary Hypertension: Randomized Controlled Trial.

BACKGROUND: Hypertension is a major cause of mortality in cardiac, vascular, and renal disease. Effective control of elevated blood pressure has been shown to reduce target organ damage. A Web-based self-titration program may empower patients to control their own disease, share decisions about antihypertensive dose titration, and improve self-management, ultimately improving health-related quality of life. OBJECTIVE: Our primary aim was to evaluate the effects of a Web-based self-titration program for improving blood pressure control in patients with primary hypertension. Our secondary aim was to evaluate the effects of that program on improving health-related quality of life. METHODS: This was a parallel-group, double-blind, randomized controlled trial with assessments at baseline, 3 months, and 6 months. We included patients with primary hypertension (blood pressure>130/80 mm Hg) from a cardiology outpatient department in northern Taiwan and divided them randomly into intervention and control groups. The intervention group received the Web-based self-titration program, while the control group received usual care. The random allocation was concealed from participants and outcome evaluators. Health-related quality of life was measured by the EuroQol five-dimension self-report questionnaire. We used generalized estimating equations to evaluate the effects of the intervention. RESULTS: We included 222 patients and divided them equally into intervention (n=111) and control (n=111) groups. Patients receiving the Web-based self-titration program showed significantly greater improvement in the systolic and diastolic blood pressure control than those who did not receive this program, at 3 months (-21.4 mm Hg and -5.4 mm Hg, respectively; P<.001) and 6 months (-27.8 mm Hg and -9.7 mm Hg, respectively; P<.001). Compared with the control group, the intervention group showed a significant decrease in the overall defined daily dose at both 3 (-0.202, P=.003) and 6 (-0.236, P=.001) months. Finally, health-related quality of life improved significantly in the intervention group compared with the control group at both 3 and 6 months (both, P<.001). CONCLUSIONS: A Web-based self-titration program can provide immediate feedback to patients about how to control their blood pressure and manage their disease at home. This program not only decreases mean blood pressure but also increases health-related quality of life in patients with primary hypertension.

Factors Affecting Self-care Maintenance and Management in Patients With Heart Failure: Testing a Path Model.

BACKGROUND: Self-care is indispensable for health maintenance and well-being. This naturalistic decision-making process involves behavioral choices to maintain physiological stability (self-care maintenance) and response to occurring symptoms (self-care management). However, several factors affect self-care, but some have contradictory results. OBJECTIVE: We aimed to examine how depressive symptoms, social support, eHealth literacy, and heart failure (HF) knowledge directly and indirectly affect self-care maintenance and management and to identify the mediating role of self-care confidence in self-care maintenance and management. METHODS: The study included a total of 141 patients with HF (average age, 65.2 years; male, 55.3%). We analyzed their data, including demographic and clinical characteristics, obtained from the Patient Health Questionnaire-9, Multidimensional Scale of Perceived Social Support, eHealth Literacy Scale, Dutch Heart Failure Knowledge Scale, and Self-Care of Heart Failure Index. Furthermore, path analysis was conducted to examine the effects of the study variables on self-care maintenance and management. RESULTS: Self-care confidence significantly and directly affected self-care maintenance and management and mediated the relationships between factor variables (depressive symptoms, social support, and HF knowledge) and outcome variables (self-care maintenance and management). Specifically, depressive symptoms had a negative and direct effect on self-care maintenance, whereas eHealth literacy had significant and direct effects on self-care management and HF knowledge. CONCLUSION: Self-care confidence decreases the negative effects of depressive symptoms on self-care. This study underscores the need for interventions targeting patients' self-care confidence to maximize self-care among patients with HF.

Effect of Home Medication Titration on Blood Pressure Control in Patients With Hypertension: A Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Medication titration has been used in home blood pressure (BP) control, with the expectation of enabling patients with hypertension to better manage their BP. OBJECTIVE: The study goal was to estimate the effects of medication titration intervention in lowering the systolic blood pressure and diastolic blood pressure of patients with hypertension. METHODS: The meta-analysis included randomized controlled trials on adults diagnosed with hypertension and BP≧130/80 mm Hg, having a medication-titration intervention, and using a home BP measurement. We systematically searched PubMed, CINAHL, Ovid-Medline, and the Cochrane Library, for studies published from 1997 to 2017. The quality of the studies was evaluated by the Modified Jadad scale. Statistical heterogeneity among the trials was evaluated using Q statistics and I. Publication bias was assessed with the funnel plot and Rosenthal's fail-safe N. RESULTS: The meta-analysis included 4 studies randomizing 1335 participants. Medication-titration intervention significantly assisted hypertensive patients to improve BP control; systolic blood pressure was reduced by 6.86 mm Hg [95% confidence interval (CI), 4.80-8.93, P<0.0001] and diastolic blood pressure by 3.03 mm Hg (95% CI, 2.07-3.99, P<0.0001), did not significantly affect EQ-5D scores (mean difference, 0.02; 95% CI, -0.01 to 0.04, P=0.13). CONCLUSIONS: Our findings suggest home medication titration of antihypertensive medication for hypertensive patients significantly improved home BP control. However, the strategy did not enhance quality of life in patients with hypertension.

[The Effect of Exercise Training on Heart Rate Variability in Patients With Hemodialysis: A Systematic Review].

BACKGROUND: More than 50% of hemodialysis patients exhibit autonomic dysfunction and impaired heart rate variability, which are linked to cardiovascular symptoms and poor health outcomes. While exercise training has been shown to positively affect heart rate variability in patients with chronic diseases, there is insufficient evidence to support similar effects in hemodialysis patients. PURPOSE: In order to give hemodialysis patients more objective information about exercise therapy, this study reviews the literature systematically to evaluate the effect of exercise training on heart rate variability in hemodialysis patients and establishes evidence-based recommendations for exercise training on heart rate variability in hemodialysis patients. METHODS: A systematic search of Cochrane Library, PubMed, CINAHL, MEDLINE, and CEPS was conducted. The keywords used in the search included "hemodialysis / haemodialysis", "exercise / exercise training / physical training / aerobic exercise / resistance exercise / strength training", and "heart rate variability / HRV / autonomic nervous system". Only randomized controlled trials (RCT) studies from the years 1990 to August 2018 were included. Non-adult ( ≤ 18 years) studies, non-English / non-Chinese language studies, and review studies were excluded. RESULTS: Four studies were found and included in the analysis. Exercise training to hemodialysis patients improved the heart rate variability significantly to various degrees, including a medium to large effect for the standard deviation of all normal-to-normal intervals (SDNN), a large effect for the root mean square of the successive differences (RMSSD), a large effect for the proportion of differences of adjacent RR intervals > 50 ms (pNN50), a medium effect for the HRV triangular index, a medium effect for the low frequency/high frequency (LF/HF) ratio, and a small to medium effect for the mean RR interval. Based on the results of this systematic literature reviews recommendations emerged for exercise training on heart rate variability in hemodialysis patients. This recommendations regard to the exercise training time, frequency, intensity and contradictions. CONCLUSIONS: The results of this systematic review support that the parasympathetic activity, sympathetic activity, and heart rate variability of hemodialysis patients increase close to the normal value after exercise training. Based on the results of systematic literature reviews, this study establishes four evidence-based recommendations for exercise training on heart rate variability in hemodialysis patients. These recommendations are valid, as all levels of evidences are 1++ and the grades of recommendations range from A to B.

Uncertainty and depressive symptoms as mediators of quality of life in patients with heart failure.

Uncertainty in illness is regarded as a source of stress in many chronic diseases and is negatively related to health-related quality of life (HRQoL). However, studies on the relationship between uncertainty and HRQoL in patients with heart failure are limited. This study used Mishel's theory of uncertainty in illness to investigate the mediating role of uncertainty in illness and depressive symptoms between symptom distress and HRQoL in patients with heart failure. This study used a cross-sectional correlation design. Participants were recruited by convenience sampling from outpatient services and medical wards of cardiology departments of a medical center in northern Taiwan. Data were collected for uncertainty, depressive symptoms, symptoms distress of heart failure, and HRQoL using self-report questionnaires. Demographics and clinical characteristics were analyzed with descriptive statistics. The mutual effects of disease characteristics, symptom distress, uncertainty in illness, depressive symptoms and HRQoL, as well as the overall model fitness, were analyzed by with structural equation modeling. We collected 147 qualified questionnaires. The mean score for the Mishel Uncertainty in Illness Scale for patients with heart failure was 73.5 (SD = 18.55); 65.3% of participants had a score of ≧13 on the Beck Depressive Inventory-II, indicating mild depression. Uncertainty, depressive symptoms, and HRQoL were directly related to symptom distress. Symptom distress and depressive symptoms were both mediators between uncertainty and depressive symptoms. Depressive symptoms also mediated emotional support and HRQoL. Uncertainty and depressive symptoms were important factors in the pathway between symptom distress and HRQoL for heart failure patients. We suggest providing heart failure patients with tailored interventions for effective self-management of symptoms based on Mishel's theory of uncertainty in illness, which could help control disease symptoms, alleviate uncertainty and depression as well as improve HRQoL.

Effectiveness of Story-Centred Care Intervention Program in older persons living in long-term care facilities: A randomized, longitudinal study.

Depression is a common issue in institutionalized elderly people. The "Attentively Embracing Story" theory is applied to help individuals transform negative thoughts into positive, and reflect on spiritual healing. This study aimed to examine the effectiveness of a "Story-Centred Care Intervention Program" based on the "Attentively Embracing Story" theory in improving depressive symptoms, cognitive function, and heart rate variability in institutionalized elderly people. Seventy long-term care residents were recruited from two long-term care facilities and randomized into the story-centred care intervention (n = 35) and control groups (n = 35). We excluded five long-term care residents who did not complete the post-test measures and five long-term care residents who had interference events on the outcome measures. Finally, sixty long-term care residents (40 women and 20 men; age 84.3±5.98 years) were included in the final analysis. Data were collected at four times (pre-intervention and post-intervention, 1 and 3-month follow-up) and analyzed with the generalized estimating equation approach.Instruments, including Geriatric Depression Scale, Short Portable Mind Status Questionnaire, and a CheckMyHeart device to measure heart rate variability, were used in study. The degree of improvement in depressive symptoms was significantly higher in the story-centred care intervention group than in the control group after providing the story-centred care intervention program (p < .001) and at 1 and 3-month follow-up (p = .001, p = .006, respectively; GDS-15 score reduced 1.816 at the 3-month follow-up). Participants receiving the story-centred care intervention program showed significantly greater improvement than those in the control group in the cognitive function at 1and 3-month follow-up (p = .009, p = .024, respectively; SPMSQ score reduced 0.345 at the 3-month follow-up). The heart rate variability parameters (SDNN, RMSSD) did not show a statistically significant increase. However an increasing trend in the parameters was observed in the intervention group (SDNN increased 16.235ms at the 3-month follow-up; RMSSD increased 16.424 ms at the 3-month follow-up). In conclusions, the story-centred care intervention program was effective on the improvement of depressive symptoms and cognitive status in institutionalized elderly people.

Effects of home-based long-term care services on caregiver health according to age.

BACKGROUND: Caregiver health is a crucial public health concern due to the increasing number of elderly people with disabilities. Elderly caregivers are more likely to have poorer health and be a care recipient than younger caregivers. The Taiwan government offers home-based long-term care (LTC) services to provide formal care and decrease the burden of caregivers. This study examined the effects of home-based LTC services on caregiver health according to caregiver age. METHODS: This cross-sectional study included a simple random sample of care recipients and their caregivers. The care recipients had used LTC services under the Ten-Year Long-Term Care Project (TLTCP) in Taiwan. Data were collected through self-administered questionnaires from September 2012 to January 2013. The following variables were assessed for caregivers: health, sex, marital status, education level, relationship with care recipient, quality of relationship with care recipient, job, household monthly income, family income spent on caring for the care recipient (%) and caregiving period. Furthermore, the following factors were assessed for care recipients: age, sex, marital status, education level, living alone, number of family members living with the care recipient, quality of relationship with family and dependency level. The health of the caregivers and care recipients was measured using a self-rated question (self-rated health [SRH] was rated as very poor, poor, fair, good and very good). RESULTS: The study revealed that home nursing care was significantly associated with the health of caregivers aged 65 years or older; however, caregivers aged less than 65 who had used home nursing care, rehabilitation or respite care had poorer health than those who had not used these services. In addition, the following variables significantly improved the health of caregivers aged 65 years or older: caregiver employment, 20% or less of family income spent on caregiving than 81%-100% and higher care recipient health. The involvement of daughters-in-law, rather than spouses, and care recipient health were positively related to the health of caregivers aged less than 65 years. CONCLUSIONS: The findings suggest that home-based LTC service use benefits the health of elderly caregivers. By contrast, home-based LTC service use may be negatively correlated with the health of the caregivers aged less than 65 years.

[The Utilization of Health-Related Applications in Chronic Disease Self-Management].

The dramatic increase in smartphone usage has spurred the development of many health-related mobile applications (apps). On the other hand, population aging and the associated rise in the incidence of chronic disease is increasing the demand for long-term care. Effective chronic disease self-management has been shown to help patients improve their health condition. Numerous smartphone applications currently support patient self-management of chronic disease, facilitating health management and health promotion. The purpose of the present article was to introduce the definition, contents, and types of health-related apps; to discuss the effectiveness of self-management health-related apps in promoting chronic disease management; and to assess and evaluate these apps. We hope that the present article helps give to healthcare professionals and patients who are willing to manage their diseases a general understanding of health-related apps and their potential to facilitate the self-management of chronic diseases.

Effect of psycho-educational interventions on quality of life in patients with implantable cardioverter defibrillators: a meta-analysis of randomized controlled trials.

BACKGROUND: Implantable cardioverter defibrillators (ICD) were developed for primary and secondary prevention of sudden cardiac death. However, ICD recipients' mortality is significantly predicted by their quality of life (QOL). The aim of this meta-analysis was to evaluate the effects of psycho-educational interventions on QOL in patients with ICDs. METHODS: We systematically searched PubMed, Medline, Cochrane Library, and CINAHL through April 2015 and references of relevant articles. Studies were reviewed if they met following criteria: (1) randomized controlled trial, (2) participants were adults with an ICD, and (3) data were sufficient to evaluate the effect of psychological or educational interventions on QOL measured by the SF-36 or SF-12. Studies were independently selected and their data were extracted by two reviewers. Study quality was evaluated using a modified Jadad scale. The meta-analysis was conducted using the Cochrane Collaboration's Review Manager Software Package (RevMan 5). Study heterogeneity was assessed by Q statistics and I 2 statistic. Depending on heterogeneity, data were pooled across trials using fixed-effect or random-effect modeling. RESULTS: Seven randomized controlled trials fulfilled the inclusion and exclusion criteria, and included 1017 participants. The psycho-educational interventions improved physical component summary (PCS) scores in the intervention groups more than in control groups (mean difference 2.08, 95 % CI 0.86 to 3.29, p < 0.001), but did not significantly affect mental component summary (MCS) scores (mean difference 0.84, 95 % CI -1.68 to 3.35, p = 0.52). CONCLUSION: Our meta-analysis demonstrates that psycho-educational interventions improved the physical component, but not the mental component of QOL in patients with ICDs.

[Health Technology Dependency: A Concept Analysis].

Health technology dependence is a widely recognized concept that refers to the utilization of technology, including drugs, equipment, instruments, and related devices, to compensate for a physical disability or to prevent the progression of a disability. Although technology may significantly prolong the life of a patient, technology may also increase the psychological pressure of these patients and the burdens of their caregivers. There is a current dearth of related research and discussions related to the concept of "health technology dependency". Therefore, the present paper uses the strategies of concept analysis described by Walker & Avant (2010) to analyze this concept. The characteristic definition of health technology dependence addresses individuals who: (1) currently live with health technology, (2) may perceive physical or psychological burdens due to health technology, and (3) feel physical and psychological well-being when coping positively with their health technology dependency and, further, regard health technology as a part of their body. Further, the present paper uses case examples to help analyze the general concept. It is hoped that nurses may better understand the concept of "health technology dependency", consider the concerns of health-technology-dependent patients and their families, and develop relevant interventions to promote the well-being of these patients and their families.
