Aims Although many studies have examined the predictors of medication adherence (MA), further empirical research is required to clarify the best model for predicting MA for older adults with heart failure (HF). Thus, we hypothesized a model in which information (knowledge), motivation (social support and depressive symptoms), and behavioural skills (barriers to self-efficacy) would be associated with MA in patients with HF. Methods and results Using a cross-sectional survey, 153 adults aged ≥ 65 years taking medication for HF were recruited from a university hospital in Korea. Data were collected based on the information–motivation–behavioural skills (IMB) model constructs and MA. In the hypothesized path model, self-efficacy was directly related to MA (β = −0.335, P = 0.006), whereas social support was indirectly related to MA through self-efficacy (β = −0.078, P = 0.027). Depressive symptoms were directly related to MA (β = 0.359, P = 0.004) and indirectly related to MA through self-efficacy (β = 0.141, P = 0.004). The hypothesized MA model showed a good fit for the data. Knowledge, social support, and depressive symptoms accounted for 44.3% of the variance in self-efficacy (P = 0.004). Left ventricular ejection fraction, knowledge, social support, depressive symptoms, and self-efficacy explained 64.4% of the variance in MA (P = 0.004). Conclusion These results confirmed the IMB model's suitability for predicting MA in older adults with HF. These findings may guide and inform intervention programmes designed to alleviate depressive symptoms in older adults with HF and enhance their HF knowledge, social support, and self-efficacy, with the ultimate goal of improving their MA.

Aims and Objectives: To determine the effectiveness of nurse‐led interventions on medication adherence, medication knowledge and clinical outcomes in adults taking medication for metabolic syndrome. Background: Despite the significance of interventions designed to improve medication adherence, a systematic review of nurse‐led intervention studies for metabolic syndrome is lacking. Design: A systematic review and meta‐analysis of randomised controlled trials. Methods: The study was conducted following the PRISMA guidelines checklist. PubMed, EMBASE, PsychINFO, CINAHL, Cochrane CENTRAL and other manual sources were searched in May 2021.The quality assessment was conducted using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Comprehensive Meta‐Analysis 3.0 was used to calculate the pooled effect sizes with 95% confidence intervals. Results: This review included 20 studies of nurse‐led medication adherence interventions in 6017 adults at risk for metabolic syndrome. The pooled effect size using the random effects model indicated that nurse‐led interventions had a significantly moderate impact on enhancing medication adherence and medication knowledge and improving selected clinical outcomes of available studies in nurse‐led intervention groups compared with control groups. Duration of intervention (median 12 weeks), mode of delivery (group vs. individual) and using multiple strategies influenced outcomes of nurse‐led medication adherence interventions. The results revealed that interventions of moderate‐ to high‐quality studies were more likely to show significant improvements in medication adherence than those of low‐quality studies. Conclusion: The meta‐analyses showed that nurse‐led interventions may enhance medication adherence and knowledge and improve clinical outcomes of this population. Relevance to Clinical Practice: The findings may contribute to evidence‐based information about nurse‐led intervention and its selection of appropriate interventions for improving medication adherence in this population. Patient or public contribution: Patients or the public were not directly involved in this review. [ABSTRACT FROM AUTHOR]

The purpose of this meta-analysis was to examine the effectiveness of aerobic exercise interventions on cardiopulmonary function and body composition in women with breast cancer. Of 24 relevant studies reviewed, 10 studies (N = 588) met the inclusion criteria. The findings indicated that aerobic exercise significantly improved cardiopulmonary function as assessed by absolute V[O.sub.2] peak (standardized mean difference [SMD] .916, p < .001), relative V[O.sub.2] peak (SMD .424, p < .05), and 12-minute walk test (SMD .502, p < .001). Similarly, aerobic exercise significantly improved body composition as assessed by percentage body fat (SMD -.890, p < .001), but body weight and lean body mass did not change significantly. Aerobic exercise during or after cancer adjuvant therapy seems to be an effective means of improving cardiopulmonary function and decreasing percentage body fat in women with breast cancer. Further studies are needed to examine the long-term benefits of aerobic exercise. Keywords: exercise; meta-analysis; breast cancer; cardiopulmonary function; body composition

This study examined the psychometric properties of the Korean version of the Patient Knowledge Questionnaire-Osteoarthritis (PKQ-OA-K). A cross-sectional survey was conducted with 157 adults with osteoarthritis from the outpatient clinic at a university hospital in Korea. The overall correct answer rate for the PKQ-OA-K was 60.4%; notably, the drug therapy subscale had the lowest median score percentage (42.9%). For structural validity, exploratory factor analysis identified the PKQ-OA-K as two-dimensional, explaining 52.4% of the total variance. Confirmatory factor analysis showed that the two-factor model adequately fit the data. The PKQ-OA-K was positively correlated with education level (r = 0.24) and osteoarthritis outcomes (r = 0.17), thus verifying the hypotheses of construct validity. The intraclass correlation coefficient for test-retest reliability was 0.52; alpha was 0.44. The PKQ-OA-K has excellent validity but imperfect reliability for adults with osteoarthritis. This study recommends cautious use of the PKQ-OA-K to assess Korean patients' knowledge of osteoarthritis. [ABSTRACT FROM AUTHOR]

Purpose : This study examined factors influencing the attitudes towards nurse-led defibrillation in the emergency department (ED) and intensive care unit (ICU). Methods : This was a cross-sectional study. A total of 212 nurses in the ED and ICU from three general hospitals responded to the survey. Data were collected between September and October 2015 using structured questionnaires. Independent t-test, Mann-Whitney U test, one-way analysis of variance (ANOVA), Pearson's correlation coefficient, and hierarchical multiple regression were used to analyze factors affecting nurses' attitudes towards nurse-led defibrillation. Results : The mean score of nurses' attitudes towards nurse-led defibrillation was 61.37 of a possible 91. Hierarchical multiple regression showed that nurses' attitudes towards nurse-led defibrillation were significantly affected by their experiences regarding cardiopulmonary resuscitation ( p=.003), knowledge regarding electrocardiogram interpretation and defibrillation ( p=.007), and tenure in ED or ICU ( p=.043). Conclusion : Results indicate that employers should set policies to support nurses in maintaining their careers in the ED or ICU and conduct systematic educational programs for them. This will increase nurses' confidence in performing defibrillation, which will lead to early defibrillation during in-hospital cardiac arrest. Consequently, it can be a strategy to increase the survival rate of cardiac arrest patients. [ABSTRACT FROM AUTHOR]
