The use of complementary and alternative medicine (CAM) is currently widespread and appears to be growing. As an increasing proportion of the population turns to CAM therapies, whether singly or in combination with allopathic medicine, the need for quality research in this area is reinforced. Much of this research consists of clinical studies aim ed primarily at clinicians, yet challenges arising from poor methodological quality will occur w hen interpreting study findings and their implications. For clinicians to be effective consumers of the scientific literature, familiarization with the principles of evidence based medicine (EBM) is essential. The goal of this review is to introduce clinicians to the concept of critical appraisal of clinical studies and foster critical thinking when reading research articles in order to best evaluate and incorporate study findings into their daily practice.

Pragmatic clinical studies, an emerging clinical research discipline, include a wide range of studies that are largely embedded with routine clinical practice and aim to evaluate the comparative effectiveness and safety of different clinical intervention strategies. Increased availability and quality of electronic medical/health records drives the development of pragmatic clinical studies. In this review, we describe evolution of the conceptual framework of pragmatic clinical studies and share perspectives on the importance of pragmatic clinical studies in evidence-based practice for cardiovascular diseases, as a complement to conventional randomized controlled trials. We also highlight specific needs of pragmatic clinical studies in improving evidence-based practice for cardiovascular disease in Asian countries. The main challenges of pragmatic clinical studies are discussed briefly in this review.

The aim of this new statement is to provide comprehensive and timely evidence-based recommendations on stroke management for clinical practitioners. Many countries are already well engaged in developing and releasing their own clinical practice guidelines, whereas Korean Medicine (KM) is still beginning. It will take time and effort to develop evidence-based guidelines and recommendations of KM or other traditional medicine because they are weak in the area of scientific evidence. The clinical practice guideline of Korean medicine for stroke was formulated through extensive review of published literature and consensus meeting of Korean medicine specialists. This project was supported by a grant of the Oriental Medicine R&D Project, the Ministry of Health and Welfare. Referring to guidelines developed in other countries, the experts in the subject tried to organize and develop guidelines and recommendations adequate for domestic medical circumstances. In December, 2008, a multi-disciplinary team called the Evidence Based Clinical Practice Guidelines Development Group (EBCPGsDG) for Stroke was organized. The writing committee was comprised of experts in internal medicine, acupuncture, rehabilitation, and Sasang constitution. Outside specialists and associated panels were invited for consultation. The scope of the guideline encompasses acupuncture, moxibustion and herbal medicine (including Korean medicine, traditional Chinese medicine, Kampo medicine) as interventions for stroke patients. It includes statements about ischemic stroke (I63), stroke not specified as hemorrhage or infarction (I64), and sequelae of cerebrovascular disease (I69) according to the International Classification of Disease (ICD). The committee subdivided the description of herbal medications into acute stroke management, subacute stroke management, post-stroke management, and secondary prevention of stroke. Guidelines on the practice of acupuncture and moxibustion were described in order for acute stroke management, subacute stroke management, chronic stroke management, and post-stroke rehabilitation. Clinicians who are working in the field of stroke care can adopt this guideline for their practice.

현재 의료체계의 주된 변화로 근거중심의학(Evidence-based Medicine: EBM)의 전지구적확산을 꼽을 수 있다. 최근 STS 연구들은 EBM이 실제 의학 실행 속에서 어떻게 사용되고 작동하는지에 대한 검토를 수행했는데, 이 글은 이러한 맥락 속에서 전립선암 특이항원(Prostate-specific Antigen: PSA) 의 조기진단 검사 도구 사용 여부를 둘러싸고 미국에서 벌어진 논쟁을 추적한다. 본 연구는 EBM이 PSA 검사 조기진단의 지지자와 반대자 양측에서 논쟁의 자원으로 이용되었으며, 그 과정에서 '확고한 과학적 기준'을 제시할 것으로 기대되던 EBM의 과학적 증거 위계가 행위자들의 의도에 따라 사실상'유연하게' 해석되고 동원되었음을 보일 것이다. 나아가, 이 글은 현재 EBM이 PSA 검사 반대자를 지지하는 것처럼 보이는 일은 삶의 질이라는 가치가 EBM의 체계 내에 주요한 변수로 부상하는 역사적 맥락에 의해 만들어진 결과임을 드러낼 것이다. 본 사례 연구는 EBM 시대에 의료기술에 관한 논쟁을 검토하는 연구자들이 EBM이라는 대상을 주어진 것으로 간주하기 보다는 논쟁 속에서 맥락화하여 논쟁과 함께 분석해야 함을 시사한다.

Purpose: This study aimed to systematically review literature and conduct a meta-analysis to comprehensively identify and evaluate the effects of workplace risk assessment-based ergonomic intervention on work-related muscular-skeletal disorders in workers. Methods: We searched the Ovid-Medline, EMBASE, and Cochrane library and up to 2018 using search terms such as muscular-skeletal, disorder, impairment, work-related muscular-skeletal disorders, ergonomic, intervention, management with no language limitations; screened reference lists; and contacted experts in the field. Results: We identified 545 references and included 13 randomized controlled tests (3,368 workers). We judged nine studies to have a low risk of bias, while the other four studies have a high risk of bias. Conclusion: Ergonomic intervention based on risk assessment in the workplace did not significantly differ in terms of the intensity of pain or duration of workers in the workplace, but low-quality evidence decreased the frequency of musculoskeletal disorder pain in three to six months moderate-quality evidence and in six to nine months low-quality evidence. Besides, low-quality evidence to reduce discomfort and moderate-quality evidence to improve worker posture. Therefore, ergonomic intervention based on the assessment of risk factors in the workplace should be applied to reduce pain frequency and discomfort and improve workers posture among musculoskeletal disorders.

Purpose: This study was conducted to evaluate the effectiveness of an evidence-based nursing (EBN) course using action learning-based team learning in undergraduate nursing students. Methods: A quasi-experimental pretest-posttest control group design was employed. The participants who consented were 45 second-year nursing students (22 in the experimental, 23 in the control group) from a university in G-city, Korea. The intervention included lectures, practicals, team activities and reflection on overviewing EBN, formulating clinical questions, searching the evidence, and criticizing the research articles. At the beginning and the end of the 7-week EBN course, the participants completed self-reported questionnaires. Frequencies, $x^2$-test, t-test, and ANCOVA with the SPSS program 18.0, were used to analyze the data. Results: The experimental group showed significantly higher scores on EBN competency (F=25.80, p<001), information literacy (F=13.75, p=.001), and proactivity in problem solving (F=5.32, p=.026) than the control group. Conclusion: This study provides evidence that an EBN course improves undergraduate nursing students' EBN competencies, information literacy, and proactivity in problem solving. Team learning in EBN education can be an effective teaching strategy.

Objective : The purpose of this study is to examine the treatment of allergic rhinitis introduced in the Chinese guideline, and to find out the direction of evidence-establishment and applicability in developing Korean Medicine clinical practice guideline for allergic rhinitis. Method : We studied Traditional Chinese Medicine treatment of allergic rhinitis introduced in the 2018 Chinese society of allergy guidelines for diagnosis and treatment of allergic rhinitis. The treatment are classified into three categories; herbal medicines, acupuncture and the others. And we compared this guidelines with other guidelines for how they differ in description of the database, evidence of level, and strength of recommendation. Results : Herbal medicines are presented based on syndrome differentiation. The basic acupoints for allergic rhinitis are introduced as follows; Fengchi(GB20), Yingxiang(LI20), Feishu(BL13) and Taiyuan(LU9). And in comparison with other guidelines for allergic rhinitis, the Chinese guideline showed lack of description in the database, evidence of level, and strength of recommendation, though they used evidence-based models. Conclusions : Clinical practice guideline projects are also underway in Korea for benefit expansion and improving quality of medical services. It is important to develop guidelines which should be evidence-based and reflect Korean medical environment.

Countries differ in their treatment expertise and research results regarding gastric cancer; hence, treatment guidelines are diverse based on evidence and medical situations. A comprehensive and comparative review of each country's guidelines is imperative to understand the similarities and differences among countries. We reviewed and compared five gastric cancer treatment guidelines in terms of endoscopic, surgical, perioperative, and palliative systemic treatment based on evidence levels and recommendation grades, as well as the postoperative follow-up strategies for each guideline. The Korean, Chinese, and European guidelines provided evidence and grading of the recommendations. The United States guidelines suggested categories for evidence and consensus. The Japanese guidelines suggested evidence and recommendations only for systemic treatment. The Korean and Japanese guidelines described endoscopic treatment, surgery, and lymphadenectomy in detail. The Chinese, United States, and European guidelines more intensively considered perioperative chemotherapy. In particular, the indications for chemotherapy and the regimens recommended by each guideline differed slightly. Considering their medical situations, each guideline had some diversity in terms of adopting evidence, which resulted in heterogeneous recommendations. This review will help medical personnel to comprehensively understand the diversity in gastric cancer treatment guidelines for each country in terms of evidence and recommendations.
