Association between possible sarcopenia and domain-specific cognitive impairment in middle-aged and older adults: Insights from the Gan-Dau Healthy Longevity Plan.

BACKGROUND: Given the established association between sarcopenia and cognitive impairment was mainly in the older and oldest-old population or people with relatively limited education, this study extends the investigation to community-dwelling middle-to-old age adults in urban communities, emphasizing the need for preventive intervention for muscle health and healthy longevity. METHODS: Data of 712 participants from the Gan-Dau Healthy Longevity Plan were retrieved for analysis, and all participants were stratified by age (50-64, 65-74 and 75+ years old). Possible sarcopenia was defined by 2019 consensus report of the Asian Working Group for Sarcopenia (AWGS). This study used four neuropsychological tests for analysis, i.e., Mini-Mental Status Examination (MMSE), California Verbal Learning Test II (CVLT-SF), Digital Symbol Substitution Test (DSST) and Verbal fluency (VF) for global and domain-specific cognitive function. Multivariate generalized linear models (GLMs) were employed to investigate the associations between possible sarcopenia and cognitive function in each age-specific groups. RESULTS: The prevalence of possible sarcopenia increased with age, with 31.8 %, 37.7 %, and 55.6 % in participants aged 5064, 65-74 and, 75+ years, respectively. On the other hand, cognitive performance declined with age. In particular, among participants aged 75+ years with possible sarcopenia, their cognitive performance were poorer than robust counterparts, including MMSE (26.6 [3.4] vs. 27.4 [2.6]), CVTL-SF (total score: 21.5 [5.4] vs. 23.8 [5.5]; 30-second delayed recall: 6.0 [1.7] vs. 6.5 [1.6]), DSST (32.8 [14.3] vs. 41.3 [18.7]), and VF (12.8 [5.1] vs. 14.8 [4.9]). Multivariate generalized linear model indicated that possible sarcopenia was associated with lower MMSE (ß: -0.70, p = 0.014) and lower DSST (ß: -7.00, p = 0.010) in those aged 50-64 years. Moreover, possible sarcopenia was associated with lower CVLT-SF (total score ß:-1.90, p = 0.028), lower DSST (ß: -6.45, p < 0.001), and lower VF (ß: -1.64, p=0.026) in 75+ years group. CONCLUSIONS: An association exists between possible sarcopenia and cognitive impairment, encompassing global cognition, delayed memory, verbal fluency, and executive function, among community-dwelling adults of mid-to-old age. Future research is warranted to explore the temporal alterations in this association and the potential effects of interventions aimed at fostering healthy longevity.

Effects of Length of Employment and Head Nurse Leadership Style on the Clinical Competency of Staff Nurses in Taiwan.

BACKGROUND: High-quality patient care requires nurses with strong clinical competency. Thus, it is essential to examine the factors associated with clinical competency. PURPOSE: This study was designed to (a) investigate head nurse leadership, staff nurse demographics, and clinical competency; (b) examine the impact of demographics on the clinical competency of staff nurses; (c) analyze the correlation between head nurse leadership and staff nurse clinical competency; and (d) examine the effects of demographics on clinical competency after controlling for the head nurse leadership. METHODS: A cluster sampling method was used to collect data from 200 staff nurses at a national medical center in Taiwan. Questionnaires were used to gather information on head nurse leadership style and staff nurse clinical competency. Descriptive and inferential statistical analyses were conducted, including Mann-Whitney U test, Kruskal-Wallis test, Spearman's rank correlation coefficient, and multivariate analysis of covariance. RESULTS: The average score for transformational leadership style among the head nurses was 2.89, whereas transactional leadership style scored an average of 2.49. The average scores for the components of clinical competency, listed from highest to lowest, were as follows: patient care (3.35), professionalism (3.28), communication skills (3.18), management (2.84), and knowledge (2.73). In addition, statistically significant differences were found in clinical competency based on demographic factors, including age, marital status, educational level, job title, and length of employment. Also, a statistically significant, positive correlation between the head nurse transformational leadership style and nurse clinical competency was found. The main effect of length of employment on the five competency components was statistically significant after controlling for transformational leadership. Furthermore, post hoc analysis of covariance revealed a significant effect of length of employment on patient care, knowledge, communication skills, and management. CONCLUSIONS: The findings of this study indicate transformational leadership and employment length impact the clinical competency of staff nurses, particularly in terms of patient care, communication skills, management, and knowledge. Providing education and training in leadership and management to current and prospective head nurses may be expected to enhance clinical competency in staff nurses and create a more nurturing work environment. Moreover, targeted training may help current head nurses gain insight into their leadership styles and acquire skills to promote transformational leadership. In addition, leadership development may help equip prospective head nurses with critical competencies before assuming leadership responsibilities.

Preventing functional decline in hospitalized older adults in medical ward: a best practice implementation project.

INTRODUCTION AND OBJECTIVES: Functional decline frequently occurs in older adults in hospitals. The aim of this project was to promote evidence-based strategies for physical activity to prevent functional decline in hospitalized older adults in a medical center in southern Taiwan. METHODS: This project was guided by the JBI Evidence Implementation Framework. Seven audit criteria were derived from a JBI evidence summary and a baseline audit involving 25 nurses and 30 hospitalized older adults was conducted to compare current practice with best practice recommendations. The JBI Getting Research into Practice (GRiP) tool was used to identify barriers to implementation, and strategies were developed to overcome those barriers. A follow-up audit was conducted to measure any changes in compliance. RESULTS: After implementing the strategies, the pass rate of nursing staff improved in the physical activity knowledge test, rising from 56% to 88%. Compliance of nursing staff with providing physical activity instructions using evidence-based guidelines to hospitalized older adults reached 80%. The incidence of functional decline among hospitalized older adults decreased from 36.7% to 20%. CONCLUSIONS: The results of this best practice implementation project suggest that initiating physical activity as early as possible for hospitalized older adults once their medical condition has stabilized can help prevent functional decline.

The Relationship Between Resilience and Health-Related Quality of Life Among Heart Failure Patients in New York Heart Association Functional Classes II and III.

BACKGROUND: Heart failure is an intense, unpredictable, and stressful chronic disease caused by the decline in cardiac pumping function. The influence of heart failure affects patients not only in terms of physical capabilities but also in terms of their emotional and social dimensions, with patients in different functional classes experiencing different levels of effect. Although resilience and health-related quality of life have been studied in populations with heart failure, the scholarly understanding of different functional classes is limited. PURPOSE: This study was designed to investigate the relationship between resilience and health-related quality of life among patients with heart failure in different physical functional classes in Taiwan. METHODS: A cross-sectional design was applied to study patients with heart failure in northern Taiwan. Two structured questionnaires, including the Resilience Scale for Adults and the 12-item Short Form Health Survey, were used to assess resilience and health-related quality of life. New York Heart Association functional class was used to determine physical function status, and canonical correlation analysis was used to determine the weight of each resilience and quality-of-life domain for the different functional classes. RESULTS: The 100 participants had an average age of 65.52 years. Slightly over half (56%) were classified as Functional Class II. A group difference in health-related quality of life was observed. Personal strength (rs = .759) and social competence (rs = -.576) were found to influence the resilience and emotional role dimension of quality of life (rs = -.996) in the Functional Class II group. In addition, family cohesion (rs = -.922), dominant resilience, physical function (rs = .467), and bodily pain (rs = .465) were found to influence quality of life in the Functional Class III group. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The efficacy of measures taken to increase resilience to heart failure varied in patients in different functional classes. Functional Class II individuals were better able to manage the disease using their personal strength, whereas Functional Class III individuals relied more heavily on family support and assistance for this effort. Furthermore, participant feelings about quality of life also varied by functional class, with physical function and bodily pain taking on significantly more importance for Functional Class III individuals.

Dignity, Resilience, and Quality of Life in Patients With Cardiac Disease: A Partial Least Squares Structural Equation Modeling Approach.

BACKGROUND: Health-related quality of life (HRQoL) is an important indicator of patient's satisfaction about their disease course. Many factors are influential to life quality, such as dignity and resilience. Dignity is mostly explored in populations with cancer, but the understanding of dignity and its relationship with resilience and HRQoL is limited. OBJECTIVE: The aim of this study was to explore the relationships between dignity, resilience, and HRQoL among patients with cardiac disease. METHODS: A purposive sample of patients with cardiac disease with a cross-sectional design was used for this study. Four structured questionnaires were used for data collection. Dignity was measured by the Patient Dignity Inventory-Mandarin version; resilience was measured by the Chinese version of the Resilience Scale; HRQoL was measured by EuroQol 5 Dimensions. Partial least squares structural equation modeling was applied to test the hypothesized structural model. Reporting was consistent with the Strengthening the Reporting of Observational Studies in Epidemiology checklist. RESULTS: The mean age of all 101 participants was 72.2 years, 88.1% had coronary artery disease, and the prevalence of heart failure was 43.0%. In patients with cardiac disease, their sense of dignity was significantly associated with HRQoL, and resilience was associated with both dignity and quality of life. Notably, resilience had a mediating effect between dignity and HRQoL; dignity and resilience explained 73.0% of the variance of HRQoL. CONCLUSIONS: Dignity is a new concern in cardiac disease research, which is influential to patients' perception of disease and their HRQoL. Patients with cardiac disease with higher resilience tend to have a better HRQoL.

Flushing and locking management related to central venous catheter occlusion rate among adult patients in acute care: a best practice implementation project.

INTRODUCTION AND OBJECTIVES: A central venous catheter (CVC)-a type of central venous access device (CVAD)-is the most common intervention for critical illnesses. Obstruction of the CVC can lead to fatal consequences. Thus, it is critical to maintain catheter lumen patency. The CVC occlusion rate in a hospital in Taiwan was 33%. This project aimed to decrease the CVC occlusion rate in acute care. METHODS: This project was conceptually informed by the JBI Evidence-Based Model of Healthcare, in particular, the conceptualization of evidence implementation as inclusive of context analysis, implementation, and evaluation of outcomes using evidence-based quality indicators. As part of the seven-phase implementation process, we used audit and feedback in a pre- and post-test design to measure baseline compliance. Based on the initial audit, we developed an implementation strategy responsive to the identified gaps in compliance. We then undertook a final audit to measure changes in compliance to evaluate our implementation effects. The JBI software, PACES, and the situational analysis software, GRiP, were used for data collection and implementation planning. There were six evidence-based criteria, with a sample size of 30 nurses for each criterion. The team carried out the project from September 2022 to January 2023. RESULTS: Post-implementation audit compliance rates increased to 100% for the following criteria: the organization had a standardized flushing and locking solution protocol (0%), the CVAD lumen was locked upon completion of the final flush (10%), a single-dose system was used for flushing and locking the CVAD (60%), and preservative-free 0.9% sodium chloride was used to flush the CVAD (60%). Furthermore, the CVC occlusion rate decreased from 33% to 5%. CONCLUSIONS: The project successfully decreased the rate of CVC occlusion and increased the competence of nurses in acute care settings. The implementation of best practices in clinical care should focus on leadership, cross-department coordination, education, and innovation.

Resilience, activities of daily living, and well-being in patients with chronic kidney disease.

AIM: The aim was to investigate the associations of activities of daily living, resilience and the well-being among patients with chronic kidney disease (CKD) and provide a long-term follow-up study. DESIGN: A longitudinal design was used. METHODS: The instruments included the Instrumental Activities of Daily Living (IADLs) Scale to assess the activities of daily living as well as the Resilience Scale and Well-Being Scale. A regression analysis was used to predict the factors related to well-being. A repeated-measures ANOVA was used for long-term follow-up with regard to IADLs, resilience and well-being. RESULTS: A total of 105 eligible participants were enrolled, of whom 59% were men and 41% were women. Interactions at three time points among IADLs, resilience, and well-being were reported. IADLs were significantly and positively associated with resilience and well-being. Resilience was a significant predictor of well-being. The well-being score increased by 0.24 points for every 1-point increase in the resilience score. CONCLUSION: IADLs, resilience, and well-being are correlated in patients with CKD, and resilience is a predictor of well-being. Higher resilience is associated with higher well-being. Therefore, clinical care providers need to access the resilience level of CKD patients as early as possible and design appropriate interventions to improve mental health and quality of life.

Diagnosis and outcomes of cachexia in Asia: Working Consensus Report from the Asian Working Group for Cachexia.

Chronic diseases often lead to metabolic disorders, causing anabolic resistance and increased energy consumption, which result in cachexia. Cachexia, in turn, can lead to major clinical consequences such as impaired quality of life, shortened life expectancy, and increased healthcare expenditure. Existing international diagnostic criteria for cachexia employ thresholds derived from Western populations, which may not apply to Asians due to differing body compositions. To address this issue, the Asian Working Group for Cachexia (AWGC) was initiated. The AWGC comprises experts in cachexia research and clinical practice from various Asian countries and aims to develop a consensus on diagnostic criteria and significant clinical outcomes for cachexia in Asia. The AWGC, composed of experts in cachexia research and clinical practice from several Asian countries, undertook three-round Delphi surveys and five meetings to reach a consensus. Discussions were held on etiological diseases, essential diagnostic items for cachexia, including subjective and objective symptoms and biomarkers, and significant clinical outcomes. The consensus highlighted the importance of multiple diagnostic factors for cachexia, including chronic diseases, either or both weight loss or low body mass index, and at least one of the following: anorexia, decreased grip strength (<28 kg in men and <18 kg in women), or elevated C-reactive protein levels (>5 mg/L [0.5 mg/dL]). The AWGC proposed a significant weight change of 2% or more over a 3-6 month period and suggested a tentative cut-off value of 21 kg/m2 for low body mass index in diagnosing cachexia. Critical clinical outcomes were determined to be mortality, quality of life as assessed by tools such as EQ-5D or the Functional Assessment of Anorexia/Cachexia Therapy, and functional status as measured by the Clinical Frailty Scale or Barthel Index, with significant emphasis on patient-reported outcomes. The AWGC consensus offers a comprehensive definition and user-friendly diagnostic criteria for cachexia, tailored specifically for Asian populations. This consensus is set to stimulate future research and enhance the multidisciplinary approach to managing cachexia. With plans to develop further guidelines for the optimal treatment, prevention, and care of cachexia in Asians, the AWGC criteria are expected to drive research across chronic co-morbidities and cancer in Asia, leading to future refinement of diagnostic criteria.

The effectiveness of mind-body approaches for enhancing resilience in older adults: A systematic review and network meta-analysis.

BACKGROUND: Resilience in older adults is associated with good well-being and resilience training has been shown to be beneficial. Mind-body approaches (MBAs) combine physical and psychological training in age-appropriate exercise programs.This study aims to evaluate the comparative effectiveness of different modes of MBAs in enhancing resilience in older adults. METHOD: Electronic databases and a manual search were searched to identify randomized controlled trials of different MBA modes. Data from the included studies were extracted for fixed-effect pairwise meta-analyses. Quality and risk were assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE) and Cochrane's Risk of Bias tool, respectively. Pooled effect sizes with a standardized mean difference (SMD) and a 95% confidence interval (CI) were used to quantify the impact of MBAs in enhancing resilience in older adults. Network meta-analysis was employed to evaluate the comparative effectiveness of different interventions. The study was registered in PROSPERO (Registration No. CRD42022352269). RESULTS: Nine studies were included in our analysis. Pairwise comparisons indicated that MBAs, regardless of whether they were related to yoga, could significantly enhancing resilience in older adults (SMD: 0.26, 95% CI 0.09-0.44). With strong consistency, a network meta-analysis showed that physical and psychological programs and yoga-related programs were associated with resilience improvement (SMD: 0.44, 95% CI 0.01-0.88 and SMD: 0.42, 95% CI 0.06-0.79, respectively). CONCLUSION: High quality evidence demonstrates that two MBA modes-physical and psychological programs and yoga-related programs-enhance resilience in older adults. However, long-term clinical verification is required to confirm our results.

Cold application for pain and anxiety reduction following chest tube removal: A systematic review and meta-analysis.

AIM AND OBJECTIVES: To conduct a systematic review and meta-analysis to evaluate the effects of cold application on pain and anxiety reduction after chest tube removal (CTR). BACKGROUND: The act of removing the chest tube often causes pain among cardiothoracic surgery patients. Most guidelines regarding CTR do not mention pain management. The effects of cold application on reducing pain and anxiety after CTR are inconsistent. DESIGN: Systematic review and meta-analysis. METHODS: We searched six databases, including Embase, Ovid Medline, Cochrane Library, Scopus, the Index to Taiwan Periodical Literature System and Airiti Library, to identify relevant articles up to the end of February 2021. We limited the language to English and Chinese and the design to randomised controlled trials (RCTs). All studies were reviewed by two independent investigators. The Cochrane Collaboration's tool was used to assess the risk of bias, Review Manager 5.4 was used to conduct the meta-analysis. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology was used for assessing certainty of evidence (CoE). RESULTS: Ten RCTs with 683 participants were included in the meta-analysis. The use of cold application could effectively reduce pain and anxiety after CTR. The subgroup showed that a skin temperature drops to 13°C of cold application was significantly more effective for the immediate reduction in pain intensity after CTR compared with control group. The GRADE methodology demonstrated that CoE was very low level. CONCLUSION: Cold application is a safe and easy-to-administer nonpharmacological method with immediate and persistent effects on pain and anxiety relief after CTR. Skin temperature drops to 13°C or lasts 20 min of cold application were more effective for immediate reduction of pain intensity following CTR. RELEVANCE TO CLINICAL PRACTICE: In addition to pharmacological strategy, cold application could be used as evidence for reducing pain intensity and anxiety level after CTR.

Timed Up and Go test and gastrointestinal disorders among hospitalized older adults with fall risk.

PURPOSE OF THE RESEARCH: The study aimed to examine the correlation between underlying medical conditions and gait analysis parameters as well as determine the key determiners of fall risk. MATERIALS AND METHODS: This was a cross-sectional study. A total of 120 hospitalized older adults, recruited from a medical center in northern Taiwan, completed three instruments: the Timed Up and Go (TUG) test, a demographic questionnaire, and the Morse Fall Scale. The inferential statistics were subjected to the chi-square test, Mann-Whitney U test, Kruskal-Wallis test, and Spearman's rank correlation coefficient analysis to determine the correlations among the demographic variables, gait analysis parameters, and fall risk in elderly inpatients. Logistic regression was used to analyze the predictors of elderly inpatients' fall risk. RESULTS: The results showed that longer TUG test times, slower walking speeds, or shorter stride lengths are related to higher fall risk. The new finding was that longer TUG test times and slow gait speeds were correlated with lower gastrointestinal as well as hepatobiliary and pancreatic diseases. CONCLUSIONS: This study confirms that gait analysis parameters are significantly correlated with fall risk among older inpatients and that TUG is an important indicator of frailty, prefrailty, or metabolic state. Early detection of the symptoms of gastrointestinal disorders and the provision of adequate nutrition could potentially improve inpatients' gait and prevent falls.

Association between lifestyle-related, psychosocial factors and obesity among female adolescents in Taiwan.

PURPOSE: To examine a wide range of potential contributors to the risk of obesity in female adolescents. DESIGN AND METHODS: Data for this study were collected using a cross-sectional design. A group of 175 female adolescents were recruited, and information on their demographic characteristics, lifestyle-related behaviors, and psychosocial factors was collected using a self-administered questionnaire during September 2018 to January 2019. Data were analyzed using SPSS 24.0. RESULTS: An overestimation of body weight was negatively correlated with overweight in the female adolescents. Age at menarche was negatively correlated with the arisk of overweight. Adolescents who slept for >7 h on weekend nights were less likely to be overweight. Eating more cheese, fish, seafood, and organ meats was negatively correlated with obesity risk. The female adolescents were more likely to become overweight if they ate dinners prepared by family and experienced more disturbances from parents and other family members. CONCLUSIONS: Female adolescents are a unique population affected by obesity. Although incorporating both lifestyle-related behavioral and psychosocial factors in future investigations and developing multicomponent interventions for obesity prevention are crucial, female adolescents should receive the utmost attention from researchers to alleviate the health burden of obesity. PRACTICE IMPLICATIONS: The intertwined nature of obesity-related factors warrants future investigations to elaborate their roles interplaying with the risk of obesity. Multicomponent interventions should be developed, and nurses and health-care providers should target their efforts on obesity prevention for this specific population.

A case report of secondary synchronous diagnosis of multiple myeloma and systemic lupus erythematosus after breast cancer treatment: A CARE-compliant article.

INTRODUCTION: Breast cancer (BC) is the most diagnosed cancer worldwide. Multiple myeloma (MM) is a hematologic malignancy characterized by the overproduction of monoclonal antibodies in the bone marrow. Systemic lupus erythematosus (SLE) is distinguished by the aberrant activity of the immune system with heterogeneous clinical manifestations. The coexistence of more than one major illness in a patient can present a diagnostic challenge for clinical physicians, especially when the comorbid diseases share a similar clinical presentation. Herein, we report an unusual case of secondary synchronous diagnosis of MM and SLE after BC treatment. PATIENT CONCERNS: A 69-year-old female patient with breast cancer experienced severe skin itching and rashes on the face, anterior chest wall, back, and trunk for two days before admission. She had high levels of immunoglobulin and anti-nuclear antibodies; low levels of complements 3 and 4; positive anti-cardiolipin-IgM, anti-beta 2 glycoprotein-1 (anti-ß2GP1) antibodies, and lupus anticoagulant results at serological testing. DIAGNOSIS: The postoperative pathology report showed ductal carcinoma in situ in the right breast. SLE was confirmed based on the 2019 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) criteria. IgG-κ type multiple myeloma was confirmed by bone marrow biopsy, and the patient was synchronously diagnosed with SLE and MM after BC treatment. INTERVENTIONS: Glucocorticoids and immunosuppressive agents, including intravenous hydrocortisone (5 g every 8 hours) and oral hydroxychloroquine (Plaquenil) (200 mg twice daily) were administered to treat SLE. One capsule of thalidomide 50 mg was administered orally every night at bedtime for MM. OUTCOMES: The patient died two days later, shortly after the administration of drugs, due to multiple organ failures secondary to pneumonia and respiratory failure. CONCLUSION: This is a case of MM and SLE after BC treatment. The present challenge was the early detection and accurate diagnosis of the secondary major illnesses, as the clinical manifestations were similar and non-specific between these two diseases. Awareness and prompt recognition of the common clinical symptoms of SLE and MM should be considered by clinical physicians to avoid delayed diagnoses and facilitate early treatment for a better prognosis.

A Preliminary Study on Self-Healing and Self-Health Management in Older Adults: Perspectives From Healthcare Professionals and Older Adults in Taiwan.

The human body has tremendous self-healing capacity and regeneration after injuries and pathogen invasions. These factors are particularly important in older adults which take longer to heal and recover physically. In addition to clinical investigations, perspectives from both experts in the field and the living experiences of the general public could play significant roles to enhance the body's healing mechanisms in older adults. A semi-structured interview was conducted which included 15 participants (9 experts and 6 older adults aged 65 years and older). Content analysis with an inductive approach was employed about participants' experiences and perspectives. All participants in this study revealed that self-healing mechanisms can be enhanced through physiological, psychological, and socio-environmental factors. When more of these factors can be integrated into a recovery management plan, it can hasten self-healing in older adults. Social capability has a profound impact on an individual's mental health while oral health and hygiene significantly affect the nutritional intake status. In regards to physical aspects, regular daily activity patterns, nutritious eating, moderate exercise, and sleep quality are significant, while psychological aspects such as cheerfulness, positive attitudes, and good interpersonal relationships can help control chronic diseases.

The impact of organisational commitment and leadership style on job satisfaction of nurse practitioners in acute care practices.

AIM: This study aimed to determine the main factors that affect nurse practitioners' (NPs) job satisfaction, especially the relationship between organisational commitment and leadership styles in acute care practices. BACKGROUND: There is little known about the influence of organisational commitment and leadership on NPs' job satisfaction within acute care hospitals. METHODS: A cross-sectional design with a national online survey enrolled 1205 NPs from the Taiwan Association of Nurse Practitioners. A multiple regression model was applied to identify potential variables that associated with job satisfaction. RESULTS: Organisational commitment (mean = 59.47), job satisfaction (mean = 173.47) and leadership style (mean ranged from 13.29 to 28) were at a moderate level. Organisational commitment, leadership style, patient load and NP advancement levels explained 63% of the variance in NPs' job satisfaction. CONCLUSIONS: Organisational commitment and leadership styles, such as idealized influence and individual consideration, are major factors that impact NPs' job satisfaction. IMPLICATIONS FOR NURSING MANAGEMENT: Health care organisations should develop policies targeting organisational commitment and managers' leadership styles to improve NPs' job satisfaction.

Effects of Professional Autonomy and Leadership Style on the Team-Based Practice of Acute Care Nurse Practitioners in Taiwan.

BACKGROUND: Little is known regarding the factors that affect the team-based practice of nurse practitioners (NPs). Examining the relationships between these factors and team-based practice may provide important insights into the strength of the NP practice. PURPOSE: This study was designed to examine the effects of practice autonomy and leadership style on the team-based practice of acute care NPs working in hospitals. METHODS: A cross-sectional, national survey design was conducted to examine the autonomy, leadership, and team-based practice of NPs. One thousand three hundred ninety-one NPs completed the questionnaire, which included demographic and practice variables, the Dempster Practice Behavior Scale, the Multifactor Leadership Questionnaire, and the NP-physician relations subscale of the Nurse Practitioner Primary Care Organizational Climate Questionnaire. The hierarchical linear model was used to differentiate between the NP-level and organization-level effects on team-based practice. Multiple regression was applied to explore the factors associated with team-based practice. RESULTS: The hierarchical linear model results identified no organization-level effect on team-based practice. Moreover, the results of the regression model found that NPs with greater autonomy in actualization, empowerment and readiness, and idealized influence leadership style enhanced the performance of the doctor of medicine-NP team-based practice. The final model explained 39% of the variance in doctor of medicine-NP team-based practice. Autonomy in actualization and empowerment were identified as the two most important predictors. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The practice autonomy and leadership style of NPs influence the efficiency of team-based practice in Taiwan. To improve the team-based practice of NPs, healthcare administrators must support the practice autonomy of NPs.

[The Mediating Role of Novice Nurse Practitioner Professional Commitment on Workplace Stress and Teaching Behaviors].

BACKGROUND: Teaching is a vital competency for nurse practitioners (NP). Correlations among teaching behaviors, workplace stress, and professional commitment in novice NPs have been identified in previous research. However, the mediating effect of professional commitment on workplace stress and teaching behaviors is an issue that has been investigated in only a few studies. PURPOSE: To explore the relationships among workplace stress, teaching behaviors, and professional commitment in novice NPs and to identify the predictors and mediators of teaching behaviors. METHODS: This cross-sectional study used a sample of 79 novice NPs. The research instruments used were the Nurse Workplace Stress Scale, Nurse Professional Commitment Questionnaire, and Clinical Teaching Behavior Inventory. RESULTS: Negative correlations were found between workplace stress and professional commitment (r = -.37, p < .01) and between workplace stress and teaching behavior (r = -.27, p < .05). A positive correlation was found between professional commitment and teaching behaviors (r = .61, p < .001). Professional commitment was identified as a predictor of teaching behaviors (ß = .59, R² = .38, p < .001) and as a mediator of workplace stress and teaching behaviors (Z = -3.11, p < .001). CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The findings verified professional commitment in novice NPs to be a moderator of workplace stress and teaching behaviors. The results of this study may be used to facilitate growth in professional commitment in healthcare practice settings.

Demoralization syndrome among cardiac transplant recipients.

AIMS AND OBJECTIVES: To investigate the characteristics and prevalence of demoralisation syndrome among heart transplantation patients in Taiwan. BACKGROUND: Patients with end-stage heart failure who have undergone cardiac transplantation are at risk of demoralisation syndrome. Demoralisation syndrome has been studied in cancer populations, but our understanding of the syndrome among heart transplant recipients is limited. DESIGN AND METHODS: The study adopted a cross-sectional design and analysed the baseline data from a longitudinal study with cardiac transplant patients at a heart centre in northern Taiwan. A structured questionnaire, namely the Demoralization Scale-Mandarin Version (DS-MV), was used to assess demoralisation syndrome. Hierarchical regression was applied to determine the predictors of demoralisation. Reporting was consistent with the STROBE checklist. RESULTS: There were a total of 84 participants with an average age of 51.9 years and a time since heart transplantation of around 4.1 years. Among them, the prevalence of demoralisation syndrome was 35.8%, and 57.1% coped well with stress. In addition, on the DS-MV, participants tended to choose sentences with positive rather than negative wording. Our data showed that cardiac transplant recipients with stress have higher possibility suffering from demoralisation syndrome; poor renal function and those who cannot relive from stress are predictors for loss of meaning. CONCLUSIONS: Chinese individuals tend to hide their weaknesses; nevertheless, demoralisation syndrome among cardiac transplant recipients, as related to stress status and kidney function, is still remarkable. RELEVANCE TO CLINICAL PRACTICE: Since demoralisation is preventable, further research on this phenomenon in the cardiac transplant population is warranted and needs to be developed.
