This study surveyed dietary intake and adherence to the Korean national dietary guidelines in Korean adolescents. To elucidate basic data for use in nutrition education, which aims to improve adolescent compliance with the national dietary guidelines and to increase the intake of dietary fiber, we evaluated the sources of fiber in adolescent diets. This study included 182 male and 212 female students from 2 middle schools in the Jeonju province. From November 15~20, 2011, we surveyed the students for general characteristics, adherence to the Korean national dietary guidelines, and dietary intake. Dietary fiber intake was $16.57{\pm}6.95$ g/day for male students and $16.14{\pm}7.11$ g/day for female students. The food groups that contributed most to dietary fiber intake were (in descending order) cereals, vegetables, seasoning, and fruits. The fiber-containing food items consumed most were cabbagekimchi, cooked rice, instant noodles, and cabbage. Based on adherence to the Korean national dietary guidelines, the vegetable-based intake of dietary fiber in groups 1 (score 15~45), 2 (score 46~52), and 3 (score 53~75) were $4.41{\pm}2.595$ g/day, $4.12{\pm}2.692$ g/day, and $5.49{\pm}3.157$ g/day, respectively (p 0.001). In addition, the total intake of dietary fiber varied significantly among the three groups (p 0.001) as follows: Group 1, $14.99{\pm}6.374$ g/day; Group 2, $15.32{\pm}6.772$ g/day; and Group 3, $18.79{\pm}7.361$ g/day. In this study, we discovered that adherence to the Korean national dietary guidelines correlates with improved intake of dietary fiber. Therefore, marketing and educational development is needed to promote adherence to the Korean national dietary guidelines. In addition, nutritional education is needed to improve dietary fiber consumption through the intake of vegetables and fruits other than kimchi.

Purpose: This study evaluated real-world compliance with surgical treatment according to Korea's gastric cancer treatment guidelines. Materials and Methods: The 2018 Korean Gastric Cancer Treatment Guidelines were evaluated using the 2019 national survey data for surgically treated gastric cancer based on postoperative pathological results in Korea. In addition, the changes in surgical treatments in 2019 were compared with those in the 2014 national survey data implemented before the publication of the guidelines in 2018. The compliance rate was evaluated according to the algorithm recommended in the 2018 Korean guidelines. Results: The overall compliance rates in 2019 were 83% for gastric resection extent, 87% for lymph node dissection, 100% for surgical approach, and 83% for adjuvant chemotherapy, similar to 2014. Among patients with pathologic stages IB, II, and III disease who underwent total gastrectomy, the incidence of splenectomy was 8.08%, a practice not recommended by the guidelines. The survey findings revealed that 48.66% of the patients who underwent gastrectomy had pathological stage IV disease, which was not recommended by the 2019 guidelines. Compared to that in 2014, the rate of gastrectomy in stage IV patients was 54.53% in 2014. Compliance rates were similar across all regions of Korea, except for gastrectomy in patients with stage IV disease. Conclusions: Real-world compliance with gastric cancer treatment guidelines was relatively high in Korea.

Objective: To investigate the concordance of three international guidelines: the Korean Thyroid Association/Korean Society of Thyroid Radiology, American Thyroid Association, and American College of Radiology for thyroid nodules classified by ultrasonography (US) and the diagnostic performance of simulated size criteria for malignant biopsies. Materials and Methods: A total of 2586 thyroid nodules (≥ 1 cm) were collected from two multicenter study datasets. The classifications of the thyroid nodules were based on three different guidelines according to US categories for malignancy risk, and the concordance rate between the different guidelines was calculated for the classified nodules. In addition, the diagnostic performance of criteria related to four different simulated biopsy sizes was evaluated. Results: The concordance rate of nodules classified as high- or intermediate-suspicion was high (84.1-100%), but low-suspicion or mildly-suspicious nodules exhibited relatively low concordance (63.8-83.8%) between the three guidelines. The differences in sensitivity, specificity, and accuracy between the guidelines were 0.7-19.8%, 0-40.9%, and 0.1-30.5%, respectively, when the original biopsy criteria were applied. The differences decreased to 0-5.9%, 0-10.9%, and 0.1-8.2%, respectively, when simulated, similar biopsy size criteria were applied. The unnecessary biopsy rate calculated with the original criteria (0-33.8%), decreased with the simulated biopsy size criteria (0-8.7%). Conclusion: We found a high concordance between the three guidelines for high- or intermediate-suspicion nodules, and the diagnostic performance of the biopsy criteria was approximately equivalent for each simulated size criterion. The difference in diagnostic performance between the three guidelines is mostly influenced by the various size thresholds for biopsies.

Objective: To assess compliance with Korean guidelines for embryo transfer, the possible reasons for non-compliance, and multiple pregnancies according to each specific condition in compliant cycles. Methods: A single-institution, retrospective study was conducted of 256 fresh in vitro fertilization cycles during 2012-2014. To assess compliance with Korean guidelines, the maximum recommended number of embryos transferred (according to criteria of age, transfer day, and presence of favorable conditions) was compared with the actual number of embryos transferred. Clinical pregnancy rate (PR) was assessed as the percentage of pregnant women resulting from each set of transfer conditions, including the number of embryos transferred. The multiple pregnancy rate (MPR) was calculated as the percentage of pregnant women with a multifetal pregnancy. Results: The compliance rate with the Korean guidelines was 96.5% (247/256). Non-compliance occurred in nine cycles owing to poor embryo quality, repeated implantation failure, or hostile endometrium. In compliant cycles, the PR was 31.2% (77/247), and the MPR was 27.3% (21/77; 20 twins and one triplet). Higher MPR was noted in two types of transfer conditions: transfer of three cleavage embryos in women aged 35-39 years with favorable conditions (66.7%; primarily from those aged 35-37 years) and transfer of two blastocysts in women aged ${\geq}40$ years with favorable conditions (50%). Conclusion: Under the Korean guidelines, compliance rate was high in our center. Multiple pregnancies occurred primarily in group with favorable conditions. In high-risk groups for multiple pregnancies, reducing number of embryos transferred should be considered than suggested in the guideline.

Background : Clinical practice guidelines are an increasingly familiar part of clinical practice. Moreover, rigorously developed evidence based guidelines has been widely used. However, in Korea, some of published documents as clinical practice guidelines have shown considerable disparity in structure, contents and quality. This is mainly because there is no consensus on the definition and quality standard of clinical practice guidelines. The purpose of this study was to draw consensus on the definition and the quality standard about clinical practice guidelines. Method : We developed a questionnaire about the definition of clinical practice guidelines with inclusion criteria(23 items) and the quality standard(30 items). We selected 9 experts who had prior experience in developing and implementing guidelines. Rating methods for appropriateness of items were adopted from the RAND method. Consensus was drawn in three rounds. Results : Of the 47 items agreed, 40 items were determined to be appropriate. Clinical practice guidelines were defined as "scientifically and systematically developed statements to assist practitioners and patients on making decisions about appropriate health care for specific clinical circumstances." Narrative reviews, systematic reviews or health technology assessment without recommendations, translation of foreign guidelines, guidelines for patients only and training manuals were not considered as clinical practice guidelines. For the quality standard of clinical practice guidelines, 27 items were deemed necessary. Conclusions : The consensus on the definition with inclusion criteria and the quality standard of clinical practice guidelines carries an important meaning as the first attempt to draw a general agreement in our society. The unique achievement of the consensus reflects the current status of clinical practice guidelines that there has been a high tendency to adapt foreign guidelines. We hope efforts of this kind will continue to bring improvement in clinical practice guidelines.

Purpose: This study was conducted to construct evidence based clinical guidelines and to develop nursing process based performance measures for prevention and management of pressure ulcers, falls and pain. Method: Clinical guidelines were drafted through a comprehensive review of relevant literature, national guidelines and hospital protocols. The proposed guidelines were reviewed by a panel of experts and 90 hospital nurses, and refined on the basis of their suggestions. Nursing process based performance measures were developed based on the clinical guidelines and content validity was examined by surveys from 90 hospital nurses. Results: All items, except timetable for position change and pressure ulcer nursing record, in the guidelines for prevention and management of pressure ulcer were appropriate. Most items, except fall risk assessment tools, were appropriate for the guidelines of fall prevention. All other items, except the purpose of pain management, were appropriate for the guidelines of pain management. Performance measures developed in this study were acceptable as a tool to evaluate quality of nursing care. Conclusion: Nursing process based performance measures provide important indicators to monitor whether necessary nursing care is implemented and can be used as the primary resources to improve quality of nursing services.

Purpose: The purpose of this study was to examine the effect of patient surveillance on nurses' adherence to the guidelines on peripheral vascular catheter management. Method: A one group time series design was used. Seventy six nurses participated in the study. The data were collected from October 1 to November 4, 2008. Result: The effects of patient surveillance were significant on nurses' average adherence rates to the guidelines estimated by observers and by themselves, and the levels of nurses self recognition on the importance of the guidelines. In addition, overall occurrence rates of phlebitis tend to decrease after patients surveillance. Even though 33 nurses didn't follow the guidelines perfectly, most patients did not provide feedbacks to the nurses' non-adherence. Among the nurse participants, 36.8% answered that patient surveillance was acceptable. Conclusion: This study found that patients with peripheral catheters could positively influence nurses' adherence to the catheter management guidelines. Therefore, inviting patients in nursing activities could benefit to the quality of patients care. However, it seems essential to create an environment fostering nurses' acceptance of the patients' surveillance. Further research warrants the potential benefits of the patient's participations in nursing activities.

The purpose of this study was to develop science research ethics guidelines for elementary school teachers. To develop the guidelines, authors have conducted the following procedures: Development of guidelines through literature reviews; and an application of the developed guidelines to classroom sites. Authors established sections and formats of guidelines for science research ethics through literature reviews and developed contents of major sections and subsections and their explanations and descriptions. After that, authors applied the developed guidelines at elementary science classes and collected data through semi-structured interviews with science class teachers and checklists to reflect on and complement the contents of the guidelines. To secure the validity of guidelines, authors requested a validity assessment to four science education experts and one ethics education specialist. As a result, the CVI for the guidelines was found to be 0.9. Finally, authors developed the final guidelines by adding "Case Examples of Application" by adopting requests of elementary school teachers who used the provisional guidelines.

Objective: Dyslipidemia is recognized as a prominent risk factor for cardiovascular and cerebrovascular diseases but it is manageable through therapeutic and lifestyle intervention. Interpreting the latest guidelines is essential for an application of recommendation from guidelines into clinical practice. Therefore, this study aimed to compare the most recent guidelines on dyslipidemia treatment recommendations in Korea and USA. Methods: This study analyzed and compared 2015 Korean guidelines for the management of dyslipidemia, 2013 American College of Cardiology/American Heart Association (ACC/AHA) guideline and 2016 supportive guidelines from ACC. Results: A comparison was made focused on the following: target patients based on cardiovascular risk assessment, target goal, and treatment strategies including statin and non-statin therapies. Four target patient groups by risk were suggested in 2015 Korean guideline and cardiovascular risk factors were also considered for initiation of lipid lowering therapy. Titrated statin regimen was recommended by Korean guideline to reach LDL cholesterol and non-HDL cholesterol target level. In 2013 ACC/AHA guideline, four statin benefit group was introduced considering ASCVD risk and high intensity statin or intermediate intensity statin use were recommended without dose titration. 2016 update was to support non-statin therapy based on updated evidence and new consideration of ezetimibe, PCSK9-inhibitor and bile acid sequestrant was brought up. Conclusion: Guidelines are continuously updating as new and important clinical data are constantly released along with the advent of newly approved drugs for lipid disorder. This article provides resources that facilitates uptake of these recommendations into clinical practice.
