Clinical practice guidelines (CPG) can be defined as systematically developed recommendations and related content obtained by reviewing scientific evidence, which help healthcare providers make decisions. CPG is one of the most powerful tools that helps clinicians make evidence-based decisions in practice. Methodologies in areas essential for CPG development, such as for systematic review, risk of bias (ROB) assessment, adaptation, and the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations, are rapidly developing. Therefore, they must be well-understood and applied to evidence-based CPG development. In this regard, it is necessary to learn about the updates and changed in the methodologies for CPG development. This manuscript covers the following CPG development methodologies: (1) main principles of CPG, (2) managing conflict of interest, (3) considering patient value and preference, (4) determination of key questions, (5) ROB assessment, (6) adaptation, (7) rapid guideline development, (8) living guideline development, and (9) GIN-McMaster Guideline Development Checklist.

Aging has become a global problem, and the interest in healthy aging is growing. Healthy aging involves a focus on the maintenance of the function and well-being of elderly adults, rather than a specific disease. Thus, the management of frailty, which is an accumulated decline in function, is important for healthy aging. The adaptation method was used to develop clinical practice guidelines on frailty management that are applicable in primary care settings. The guidelines were developed in three phases: preparation (organization of committees and establishment of the scope of development), literature screening and evaluation (selection of the clinical practice guidelines to be adapted and evaluation of the guidelines using the Korean Appraisal of Guidelines for Research and Evaluation II tool), and confirmation of recommendations (three rounds of Delphi consensus and internal and external reviews). A total of 16 recommendations (five recommendations for diagnosis and assessment, 11 recommendations for intervention of frailty) were made through the guideline development process. These clinical practice guidelines provide overall guidance on the identification, evaluation, intervention, and monitoring of frailty, making them applicable in primary care settings. As aging and “healthy aging” become more and more important, these guidelines are also expected to increase in clinical usefulness.

Background : When research based evidence is not sufficient, clinical practice guidelines can be based on opinions. In such situations, formal consensus development methods, often based on the modified nominal group techniques are widely used. It can be used to evaluate consistency, generalizability, applicability of recommendation when evidence comes from other countries.
Methods : To develop evidence based guidelines for osterarthritis pharmacotherapy, a consensus expert panel consisting of internists, family physicians, methodologists, and orthopedic surgeons were convened. After an extensive structured literature searching and evaluation, evidence statements for key question were developed. Rating methods for consistency, generalizability, applicability of statement were adopted from those jointly developed by Rand and the University of California, Los Angeles.
Results : We developed 27 evidence statements in 17 question domains. Among 72 rating items, 62 items reached agreement. Among 15 recommendations, 10 recommendation grading were A, 2 were B, and 3 were C.
Conclusion : When research based evidence is not sufficient, clinical practice guidelines can be based on formal consensus of experts, especially modified nominal group techniques. It can be used to evaluate consistency, generalizability, applicability of recommendation when evidence comes from other countries.

Background : One method for achieving medical practice to be more evident, especially in the field of primary care, is to encourage the use of clinical guidelines. If development of guidelines is difficult because of time and cost, an evidence based foreign guidelines can be selected and translated into Korean for application.
Methods : A team was formed, consisting of 11 family physician experts on evidence based medicine and clinical practice guidelines. We selected six respiratory diseases requiring clinical guidelines because of variability in practice. We searched several clinical practice guideline databases and selected one guideline according to currency, scope of guideline, whether it was evidence based, and its feasibility in the field of primay care. We translated selected guideline's full-texts or summaries which were done by authorized organization into Korean.
Results : The selected respiratory diseases were chronic obstructive pulmonary disease, asthma, pneumonia, sinusitis, rhinitis, and influenza. According to criterion, we selected GOLD (Global Initiative for Chronic Obstructive Lung Disease) for chronic obstructive lung disease, GINA (Global initiative for asthma) for asthma, CDC (Center for disease control) guideline for influenza, IDSA (Infectious Diseases Society of America) guideline for pneumonia, AAP (American Academy of Pediatrics) guideline for sinusitis, and JCAAI (Joint Council of Allergy, Asthma and Immunology) for rhinitis.
Conclusion : We selected six common respiratory diseases and the most appropriate evidence based guidelines for those particular diseases.
