Purpose: This study aimed to provide a systematic review of the evidence from controlled trials regarding nursing intervention studies on patients undergoing percutaneous coronary intervention, a discussion of the methodological problems that limit current research, and suggestions regarding future directions for research. Methods: Using a predefined protocol, 27 electronic databases were searched, studies selected, relevant data extracted, and the methodological quality of the studies assessed. Results: Twenty-seven studies were found reporting complex, generally heterogeneous interventions. The studies reported positive results, including self-efficacy, knowledge, and self-care. There were 6 randomized controlled trials, 19 quasi-experimental studies, and 2 only research group studies. In addition to support components, the interventions included elements of teaching, counseling, and education. Nursing interventions are still in the developmental and testing phase. Conclusion: The review demonstrated that a great deal is known about nursing intervention, the impact on a range of outcomes, and methodology. Although some useful evidence was reported for all interventions, further research needs to be carried out.
Background Patients with atrial fibrillation (AF) require continuous self-care due to possible complications and side effects from treatment. However, existing tools do not capture all of the critical factors of AF self-care and have limited evidence of reliability and validity. Aims The aim of this study was to develop and evaluate a new Atrial Fibrillation Self-Care Scale-10 (AF-SCS-10) that assesses disease-specific, multidimensional, person-centered self-care for AF patients in South Korea. Methods For this cross-sectional research design, 290 individuals over 20 years of age with a diagnosis of AF for at least three months were recruited. A literature review and in-depth interviews were utilized to identify the scale items. An expert panel evaluated the validity and reliability of a preliminary scale. Exploratory factor analysis and parallel analysis was performed to extract factors; confirmatory factor analysis (CFA) was performed to evaluate fit on the factor structures. Criterion validity was supported by the correlation between AF-SCS-10 and AF quality of life. Results The internal consistency reliability coefficient was 0.87. Three factors, “self-care knowledge,” “self-care behavior,” and “self-care resources” were extracted from the exploratory factory analysis, explaining 79.30% of the total variance in the data. The three-factor model was also confirmed by parallel analysis; CFA met the fitness criteria. Conclusion There is preliminary evidence for internal consistency reliability, as well as content and construct validity, for the AF-SCS-10. Future research is needed to confirm the study results using a larger, more culturally diverse sample.
The purpose of this study was to analyze the current status of studies related to the learning methods of biological nursing subjects in Korea. Methods: Five databases (KoreaMed, KMbase, NDSL, KISS, KiSTi) and grey literature were searched prior to February 2018. A total 12 studies met the inclusion criteria including 11 articles and 1 proceeding. Results: We included five experimental studies, five non-experimental studies, and two mixed method studies. First, most of the studies that applied a learning method focused on the subject of human anatomy and physiology; team-based learning was the method that was utilized the most. Second, the necessity of well-designed research was confirmed because the quality of included studies was low. Third, the research variables identified were mainly concentrated on the affective domain, and included satisfaction, motivation, self-efficacy, self-directed learning, confidence, attitude. We confirmed the need to develop a learning program that can also improve the cognitive and psychomotor domain variables in future research. Conclusion: The results of this study suggest that further research should be conducted with consideration the domain of research variables evenly. In addition, future studies should apply various learning methods and included randomized controlled trials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
