Synthesizing Quantitative Evidence for EBN: Systematic Review
오의금 한국간호과학회 2016 Asian Nursing Research Vol.10 No.2
As evidence-based practice has become an important issue in healthcare settings, the educational needs for knowledge and skills for the generation and utilization of healthcare evidence are increasing. Systematic review (SR), a way of evidence generation, is a synthesis of primary scientific evidence, which summarizes the best evidence on a specific clinical question using a transparent, a priori protocol driven approach. SR methodology requires a critical appraisal of primary studies, data extraction in a reliable and repeatable way, and examination for validity of the results. SRs are considered hierarchically as the highest form of evidence as they are a systematic search, identification, and summarization of the available evidence to answer a focused clinical question with particular attention to the methodological quality of studies or the credibility of opinion and text. The purpose of this paper is to introduce an overview of the fundamental knowledge, principals and processes in SR. The focus of this paper is on SR especially for the synthesis of quantitative data from primary research studies that examines the effectiveness of healthcare interventions. To activate evidence-based nursing care in various healthcare settings, the best and available scientific evidence are essential components. This paper will include some examples to promote understandings.

Purpose: The purpose of this study was to analyze the trend of research on the use of home-based pulmonary rehabilitation. Method: Using Medline and CINAHL search engine, experiemental research, titled as 'home-based pulmonary rehabilitation' and 'chronic lung disease', statistics were collected. The total 29 experimental studies published between 1981 to 2000 were selected and analyzed according to the ATS guidelines. Result: 1) The study samples in research were mostly of men, whose lung function was moderate to severe. 2) The total period of the intervention program varied from 5 to 12 week. The program included excercise intervention and educational intervention. Psychosocial intervention was minimal. 3) The outcome of the home-based pulmonary rehabilitation had been measured mostly by physical aspects. Quality of life and cost were less frequently measured. 4) In terms of effectiveness of the home based pulmonary rehabilitation program, physiologic outcome, such as lung function and hematologic markers, there was more 'no effect' than 'positive effect', whereas there was more 'positive effect' in decreasing dyspnea, improving excercise capacity, and improving quality of life. Conclusion: Based on these findings, future research on home-based pulmonary rehabilitation should be emphasized and provide standardized protocol, including psychosocial intervention, and analyses on cost and quality of life.

The major purpose of this study was to evaluate the asthma related of life in relation to asthma control/severity, multidimensional symptom experience (frequency, intensity distress), and socioeconomic status in adults with asthma. Data was collected by mailed-survey to 384 people with asthma and 172 responded. The mean of the respondents age was 49.6 yrs. The mean of the length of time they were diagnosed as having asthma was 21 yrs. Asthma was well controlled in this sample. The findings revealed that overall asthma related quality of life were relatively good in this sample. In terms of symptom experience, shortness of breath was identified as the most frequent, severe, and distressful of the four asthma symptoms. The score for symptom distress was significantly lower than the score for the frequency and indicate that symptoms occurred frequently and intensely, but they were not always distressing to the subjects. Among the three symptom dimensions, distress was the best predictor for asthma related quality of life measured by LWAQ. Results of Multiple regression analysis indicated that asthma severity, symptom distress, and socioeconomic status influenced the quality of life(R²=.66, F(3,68)=44.37, P=.000). Findings highlight the importance of symptom distress with respect to the quality of life of people with asthma.

This study aimed to identify the level of awareness, self-efficacy, and knowledge of research ethics among nursing graduate students. A descriptive survey design was used. A total of 102 nursing graduate students were recruited from one nursing school in Korea. Data collection instruments were developed based on the core instructional areas of Responsible Conduct of Research (RCR) from the Office of Research Integrity at the research team’s institution. Participants completed a self-reported questionnaire consisting of questions on research ethics. The data were analyzed with descriptive statistics using PASW Statistics 18.0 Window program. Participants (mean age=31 years) consisted of master’s (77.5%) and doctoral (22.5%) level students. Only 25.5% of participants had taken a course in research ethics, and 26.5% of participants had experience conducting research as principle investigators. The level of awareness (mean score 2.91 out of 5) and self-efficacy for good research practice (3.15 out of 5) were moderate. The level of knowledge regarding research ethics was low (10.59 out of 16). The area of lowest awareness was ‘protection of intellectual property and patents,’ followed by ‘justifying authorship’;the area of least knowledge was ‘writing research articles,’ followed by ‘criteria for authorship.’ Statistically significant correlations were found between awareness, self-efficacy, and knowledge of research ethics (all p<0.05). These results support the conclusion that educational programs for enhancing awareness, self-efficacy, and knowledge of research ethics for graduate nursing students are needed in order to help students conduct ethically sound research.
