Purpose: The purpose of this study was to test the effects of clinical practice in school on clinical competence in nurse. Method: This study used a quasi experimental post-test design. Data were collected after post-test from April 1, 2005 to May 30, 2005 and from 73 clinical nurses(53 experimental group, 20 control group) who work for 4 General hospitals. Data were analyzed using SPSSWIN 11.5 with $X^2$-test, t-test, Mann-Whitney U-test, and stepwise multiple regression. The experimental group participated in treatment : 4-week consecutive clinical nursing education with preceptor in schooling, and the control group participated in treatment : traditional clinical nursing education with preceptor in schooling. Results: Clinical competence were significantly different between experimental and control groups(t=3.221, p=.002). Clinical competence in nurse is effected by satisfaction of clinical practice in schooling in experimental group(F=14.781, p=.000). Conclusion: 4-week consecutive clinical nursing education with preceptor has an effect on clinical competence in nurse. Therefore we should spread and reinforce the 4-week consecutive clinical nursing education program for improving clinical competence of nurse.

Purpose: This study was conducted to compare the effects of simulation-based training on knowledge, self-efficacy and clinical performance, underwent before or after the clinical practice for the nursing students. Method: A comparison group design was established with pre-clinical practice group (n=34) and post-clinical practice group (n=34). Both groups participated in simulation-based training before or after the clinical practice at the recovery room. Chi-square test, t-test and paired t-test were performed to analyze the data. Results: Both groups showed significantly higher post-test scores in knowledge and self-efficacy than pre-test scores (p<.001). The group with simulation training performed before their clinical practice (pre-clinical practice group) showed significantly higher self-efficacy (p=.044) than the group with simulation training done after their clinical practice (post-clinical practice group). However, there was no significant difference in the knowledge (p=.922) and clinical performance (p=.887). Conclusion: These findings of the study suggest that simulation based training in pre-clinical practice is effective to enhance the self-efficacy and to improve knowledge and clinical performance of the nursing students.

Purpose: This study aimed to develop a nursing simulation learning module for coronavirus disease 2019 (COVID-19) patient-care and examine its effects on clinical reasoning competence, clinical competence, performance confidence, and anxiety in COVID-19 patient care for nursing students. Methods: A non-equivalent control group pre- and post-test design was employed. The study participants included 47 nursing students (23 in the experimental group and 24 in the control group) from G City. A simulation learning module for COVID-19 patient-care was developed based on the Jeffries simulation model. The module consisted of a briefing, simulation practice, and debriefing. The effects of the simulation module were measured using clinical reasoning competence, clinical competence, performance confidence, and anxiety in COVID-19 patient-care. Data were analyzed using χ²-test, Fisher's exact test, t-test, Wilcoxon signed-rank test, and Mann-Whitney U test. Results: The levels of clinical reasoning competence, clinical competence, and performance confidence of the experimental group were significantly higher than that of the control group, and the level of anxiety was significantly low after simulation learning. Conclusion: The nursing simulation learning module for COVID-19 patient-care is more effective than the traditional method in terms of improving students' clinical reasoning competence, clinical competence, and performance confidence, and reducing their anxiety. The module is expected to be useful for educational and clinical environments as an effective teaching and learning strategy to empower nursing competency and contribute to nursing education and clinical changes.

The aim of this study was to assess the Clinical Usefulness of Helicobacter pylori Stool Antigen (HpSA) immunochromatographic assay for the diagnosis of H. pylori infection. In this study, we had compared HpSA-immunochromatographic assay with CLO test and UBT test. From a total of 140 patients (M:F=88:52) with upper endoscopy, biopsy specimens were obtained for CLO test. Stool specimens was collected from all patients and tested using a HpSA-immunochromatic assay. H. pylori infection status was defined as infected if the results of both CLO test and UBT test were positive. CLO test and UBT test findings showed that 92 patients were H. pylori positive and 48 patients were H. pylori negative. According to this definition, the sensitivity, specificity, and positive or negative predictive value (PPV, NPV) of HpSA-immunochromatographic assay were 97.8%, 100%, 100%, and 96%, respectively. Cross reactivity test of HpSA-immunochromatographic assay were performed with 10 enteric bacteria strains in fecal habitat, and there were no false positive reaction. We evaluated the usefulness of HpSA assay for eradication therapy with 10 of 92 H. pylori positive patients, positive results of them at pre-eradication therapy were converted to negative at post-eradication. The HpSA-immunochromatographic assay is a highly sensitive and specific non-invasive diagnostic method for detection of H. pylori infection, a useful diagnostic method for H. pylori in post eradication stage.

The purpose of this study was to develop a clinical pathway for the allogeneic bone marrow transplantation donor. For this study, a conceptual framework was developed through a review of the literature including six steps which are using in Jones Hopkins Hospital. USA. The researcher reviewed 129 medical re-cords of donor who had bone marrow donation between January 2002 to January 2004, to identify the overall service contents required by these patients and to make a preliminary clinical pathway. A content validity test was done for the preliminary clinical pathway, a professional group screened 51 medical re-cords and adopted with 3 hospitalization days as the clinical pathway framework. In the fifth step, clinical pathway test was also done to 7 donors from April 28th to July, 2004. After these processes the final clinical pathway was developed. The results of this study are as follows: 1. The vertical axis of the clinical pathway Includes the following 9 items: vital signs, nursing assessment, activity, diet, intervention, medication, test, consultation and patient teaching. The duration of the horizontal axis was 3days from admission to discharge 2. Analysis of the 129 medical records indicated that the average length of stay was 3 4 days. The medical performance according to the vertical axis in the preliminary clinical pathway consisted of 51 items After clinical validity test, it steel consisted of 51 items in the final form. 3. Clinical Validity test was done to 7 bone marrow donors.

In clinical decision support system(CDSS), unlike rule-based expert method, appropriate data-driven machine learning method can easily provide the information of individual feature(clinical test) for disease classification. However, currently developed methods focus on the improvement of the classification accuracy for diagnosis. With the analysis of feature importance in classification, one may infer the novel clinical test sets which highly differentiate the specific diseases or disease states. In this background, we introduce a novel CDSS that integrate a classifier and feature selection module together. Random forest algorithm is applied for the classifier and the feature importance measure. The system selects the significant clinical tests discriminating the diseases by examining the classification error during backward elimination of the features. The superior performance of random forest algorithm in clinical classification was assessed against artificial neural network and decision tree algorithm by using breast cancer, diabetes and heart disease data in UCI Machine Learning Repository. The test with the same data sets shows that the proposed system can successfully select the significant clinical test set for each disease.

Purpose: The purpose of this study was to investigate the plan to introduce a practical skills test as part of the national examination for nursing licensure. Method: The delphi method was used. The first set of data was collected by open questionnaire from universities and hospitals nationally. The second and third were collected by structured questionnaire. Results: The biggest problem for clinical Practice in nursing education was reported as the lack of opportunities for direct nursing practice. The biggest performance problem in job duties for novice nurses was reported as the lack of integrated problem solving skills in a clinical situation. The biggest problem with the current national examination was reported as the use memorizing solutions to test questions. It was suggested that the best plan to resolve problems with the national examination would be to develop test questions representative of the clinical setting and increase personnel in clinical education. About the introduction of a practical skills test as part of the national examination, 56.9% were in agreement and 38.5% disagreed. Conclusion: The current national examination has many problems when it comes to testing clinical competency. So, a practical skills test must be deferred to a future time. There are also many difficulties in presenting a real situation, therefore further research is needed in preparation for the introduction of a practical skills test.

Purpose: This study investigated the effects of reeducation of nursing process on nurses' expertise, critical thinking disposition, and clinical decision making. Methods: Data were collected from March to June, 2007. The subjects were 47 Academic Credit Bank System Student Nurses. They were taught 'nursing process' during 1 semester(15weeks). 47 nurses were divided into three groups according to clinical experience(under 3 years, 3 to under 5 years, 5 years or more). After 15 weeks, the effects of education were compared using a paired t-test between pre-test and post-test. Results: There was a significant difference in the 3 to under 5 years experienced nurses's expertise(t=-3.659, p=.004) between the pre-test and post-test. There was a significant difference in the 5 years or more experienced nurses's expertise(t=-5.781, p<.001) and critical thinking disposition(t=-3.345, p=.003) between the pre-test and post-test. There were no significant differences in clinical decision making(accuracy, proficiency, and confidence) of 3 groups. Conclusion: Reeducation of nursing process is a valuable teaching and an evaluation strategy for 5 years or more experienced nurses to improve expertise and critical thinking disposition. We need to develop continuing education program for improving nurses' clinical decision making.

Purpose: The aim of this study was to conduct a systematic review of randomized controlled studies from 2012 to present that explore the diagnostic accuracy of clinical tests used for diagnosing anterior cruciate ligament (ACL) injury. Methods: Study design: Systematic review. Literature search of the PubMed and Scholar databases was conducted using keywords related to diagnostic accuracy of clinical tests for ACL injury. The PRISMA Guidelines were followed to conduct this study. The Cochrane Risk of Bias Tool was utilized to assess the quality of each included study. Results: As a result, 8 studies were included, and 6 clinical tests used in ACL tears were evaluated for diagnostic accuracy. The pivot shift test was reported as having the highest +LR (29.5) value with a sensitivity of 59% and a specificity of 98%. However, the test with the lowest -LR value was the lever test, and the values were as follows: -LR (0.08), +LR (4.7), specificity (80%), sensitivity (94%). Conclusion: In this study, it was concluded that a single clinical test is not sufficient to determine the presence of ACL injury. Test combinations have a higher diagnostic accuracy than a single test. In this study, the accuracy of the clinical tests was examined without considering the amount of ACL rupture and acute-chronic condition. Further research is required to examine the impact of these two factors on diagnostic accuracy of clinical test.
