Associations Between Korean Coronary Heart Disease Risk Score and Cognitive Function in DementiaFree Korean Older Adults

Background@#Cardiovascular risk is a modifiable factor that can help prevent dementia.Given the dearth of optimal treatment options, managing dementia risk factors is crucial. We examined the association between cardiovascular risk, as measured by the Korean coronary heart disease risk score (KRS), and cognitive function in dementia-free elderly individuals. @*Methods@#We enrolled 8,600 individuals (average age: 69.74 years; 5,206 women) who underwent a medical evaluation from the National Health Insurance Service. KRS was calculated using age, sex, blood pressure, lipid profile, diabetes, and smoking status. Cognitive function was evaluated using Korean Dementia Screening QuestionnaireCognition (KDSQ-C). Scores of ≥ 6 indicated a cognitive decline. Logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence interval (CI). Weight, height, stroke history, coronary heart disease history, alcohol consumption, and physical activity engagement were adjusted. @*Results@#The lowest, middle, and highest groups, according to the KRS, were 5,923 (68.9%), 2,343 (27.2%), and 334 (3.9%), respectively. The highest KRS group in all participants exhibited a greater risk of cognitive decline than the lowest KRS group (OR, 1.339; 95% CI, 1.034–1.734; P = 0.027). The highest KRS female group aged 71–75 years old exhibited greater cognitive decline than the corresponding lowest KRS group (OR, 1.595; 95% CI, 1.045–2.434; P = 0.031). @*Conclusion@#Individuals with high cardiovascular risk were associated with poorer cognitive function than those with low risk, especially older women. Cardiovascular risk factors should be carefully managed to promote healthy mental aging in dementia-free elderly individuals.

Association between the Urine Cotinine Level and Blood Pressure in Korean Adults with Secondhand Smoke Exposure: Korea National Health and Nutritional Examination Survey 2016–2018 / 가정의학회지

Background@#Similar to smoking, exposure to secondhand smoke is a risk factor for developing hypertension and cardiovascular diseases; however, there is no standardized method for measuring smoke exposure. Measuring urine cotinine levels is one possible means for determining the degree of exposure to secondhand smoke. This study investigated the association between urinary cotinine levels and blood pressure in Korean adults exposed to secondhand smoke. @*Methods@#Data from the Korea National Health and Nutrition Examination Survey conducted between 2016 and 2018 were used. A total of 9,273 participants aged ≥19 years self-reported as current non-smokers, which was cotinine- verified. A complex sample general linear model regression analysis was performed to analyze the association between urine cotinine and blood pressure. A P-value of <0.05 was considered statistically significant. @*Results@#Corrected urine cotinine levels were positively associated with systolic and diastolic blood pressure in female participants (P<0.001 and P=0.040, respectively). Furthermore, a 10-fold increase in the corrected urine cotinine level of those in contact with secondhand smoke was independently associated with 2.085 mm Hg and 0.575 mm Hg increases in systolic and diastolic blood pressure, respectively. However, there was no association between systolic and diastolic blood pressure in male participants (P=0.226 and P=0.256, respectively). @*Conclusion@#Urinary cotinine levels were positively associated with increased blood pressure in females exposed to secondhand smoke. Therefore, urinary cotinine may be used as an indicator to quantify and monitor the effects of blood pressure elevation in females exposed to secondhand smoke.

Comparison between the International Classification of Primary Care and the International Classification of Diseases Classifications in Primary Care in Korea / 가정의학회지

Background@#The International Classification of Primary Care-2 (ICPC-2) is a classification method designed for primary care. Although previous studies have found that ICPC-2 is a useful tool for demonstrating the relationship between patients’ expectations and health providers’ diagnoses, its utility of ICPC-2 has yet to be fully studied in Korea. This study aimed to evaluate the practicality of ICPC-2 in Korean primary care. @*Methods@#The study was conducted at primary care clinics in Seoul and Gyeonggi areas from October to November 2015. Third-year family medicine residents examined and analyzed the medical records of patients who visited primary care physicians using ICPC-2, and the results were compared with those obtained using the International Classification of Diseases-10 (ICD-10) (Korean version: Korean Standard Classification of Diseases-7). @*Results@#A total of 26 primary care physicians from 23 primary care clinics participated in the study. Furthermore, 2,458 ICD-10 codes and 6,091 ICPC-2 codes were recorded from the data of 1,099 patients. The common disease codes were vasomotor and allergic rhinitis (J30), according to ICD-10, and acute upper respiratory infection (R74) in ICPC-2. Comparing disease status by body systems, the proportion of gastrointestinal disease with ICD-10 codes was significantly higher than that with ICPC-2 codes (P4 diagnoses accounted for 36% of the ICD-10 classifications, whereas those with >4 diagnoses accounted for 4% of the ICPC-2 classifications. @*Conclusion@#Introducing ICPC as a complementary means for diagnosing common diseases could be a practical approach in Korean primary care.

Clinical Practice Guidelines for Managing Frailty in Community-Dwelling Korean Elderly Adults in Primary Care Settings / 가정의학회지

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.

Defining Essential Topics and Procedures for Korean Family Medicine Residency Training / 가정의학회지

Background@#This study aims to create a comprehensive list of essential topics and procedural skills for family medicine residency training in Korea. @*Methods@#Three e-mailed surveys were conducted. The first and second surveys were sent to all board-certified family physicians in the Korean Academy of Family Medicine (KAFM) database via e-mail. Participants were asked to rate each of the topics (117 in survey 1, 36 in survey 2) and procedures (65 in survey 1, 19 in survey 2) based on how necessary it was to teach it and personal experience of utilizing it in clinical practice. Agreement rates of the responses were calculated and then sent to the 32 KAFM board members in survey 3. Opinions on potential cut-off points to divide the items into three categories and the minimum achievement requirements needed to graduate for each category were solicited. @*Results@#Of 6,588 physicians, 256 responded to the first survey (3.89% response rate), 209 out of 6,669 to the second survey (3.13%), and 100% responded to the third survey. The final list included 153 topics and 81 procedures, which were organized into three categories: mandatory, recommended, and optional (112/38/3, 27/33/21). For each category of topics and procedures, the minimum requirement for 3-year residency training was set at 90%/60%/30% and 80%/60%/30%, respectively. @*Conclusion@#This national survey was the first investigation to define essential topics and procedures for residency training in Korean family medicine. The lists obtained represent the opinions of Korean family physicians and are expected to aid in the improvement of family medicine training programs in the new competency-based curriculum.

Clinical Practice Guideline for Care in the Last Days of Life / 한국호스피스완화의료학회지

A clinical practice guideline for patients in the dying process in general wards and their families, developed through an evidence-based process, is presented herein. The purpose of this guideline is to enable a peaceful death based on an understanding of suitable management of patients’ physical and mental symptoms, psychological support, appropriate deci-sion-making, family care, and clearly-defined team roles. Although there are limits to the available evidence regarding medical issues in patients facing death, the final recommendations were determined from expert advice and feedback, considering values and preferences related to medical treatment, benefits and harms, and applicability in the real world. This guideline should be applied in a way that takes into account specific health care environments, including the resources of medical staff and differences in the available resources of each institution. This guideline can be used by all medical institutions in South Korea.

Association between Breakfast Skipping and Homeostasis Model Assessment of Insulin Resistance and the Atherosclerotic Cardiovascular Disease Risk in Non-Diabetic Korean Adults Aged 40–79 Years

Background@#It is reported that the decline in breakfast consumption is associated with diabetes, metabolic disease, and cardiovascular disease. This study analyzed the association between skipping breakfast and the homeostasis model assessment of insulin resistance (HOMA-IR) and atherosclerotic cardiovascular disease (ASCVD) risk among non-diabetic Korean adults aged 40–79 years who did not take medication for hypertension or dyslipidemia. @*Methods@#This study included 1,001 adults from the Sixth Korea National Health and Nutrition Examination Survey in 2015. Participants were classified into two groups based on those who skipped breakfast and those who ate breakfast. Analysis of covariance was performed to compare the average value of HOMA-IR between the two groups. Logistic regression analysis was used to evaluate the relationship between skipping breakfast and HOMA-IR and ASCVD risk. All analyses were performed after adjusting for covariates. @*Results@#There was no significant association between the group that skipped breakfast and HOMA-IR or ASCVD risk. However, the odds ratio of ASCVD risk was 3-fold higher in male in the skipping breakfast group that skipped breakfast than in those that ate breakfast. @*Conclusion@#Previous studies that suggested there was an association between skipping breakfast and ASCVD risk may have been biased as they included individuals taking medication, and thus, this could have led to incorrect results. Therefore, further studies on the association between breakfast consumption and ASCVD risk should consider practical factors that can affect eating habits, such as regular medication use in their analysis.

Factors Influencing Pain Medication Preference for Breakthrough Cancer Patients and Their Application to Treatments: Survey on Physicians / 한국호스피스완화의료학회지

PURPOSE: The purpose of this study was to assess the factors influencing the rescue medication decisions for breakthrough cancer patients and evaluate treatments using the factors. METHODS: Based on the results of an online survey conducted by the Korean Society of Hospice and Palliative Care from September 2014 through December 2014, we assessed the level of agreement on nine factors influencing rescue medication preference. The same factors were used to evaluate oral transmucosal fentanyl lozenge, oral oxycodone and intravenous morphine. RESULTS: Agreed by 77 physicians, a rapid onset of action was the most important factor for their decision of rescue medication. Other important factors were easy administration, strong efficacy, predictable efficacy and less adverse effects. Participants agreed that intravenous morphine produced a rapid onset of action and strong and predictable efficacy and cited difficulty of administration and adverse effects as negative factors. Oral oxycodone was desirable in terms of easy administration and less adverse effects. However, its onset of action was slower than intravenous morphine. While many agreed to easy administration of oral transmucosal fentanyl lozenge, the level of agreement was low for strength and predictability of its efficacy, long-term durability and sleep improvement. CONCLUSION: Rapid onset of action is one of the important factors that influence physicians' selection of rescue medication. Physicians' assessment of rescue medication differed by medication.

Physician's Attitude toward Treating Breakthrough Cancer Pain in Korea / 한국호스피스완화의료학회지

PURPOSE: Adequate control of breakthrough pain is essential for patients with cancer. Managing breakthrough pain mainly depends on understanding the concept of breakthrough pain and the proper usage of rescue medication by physicians. This study aims to assess the attitudes and practice patterns of palliative physicians in managing breakthrough pain for patients in Korea. METHODS: This study was based on data from the 2014 breakthrough cancer pain survey conducted by the Korean Society for Hospice and Palliative Care. One hundred physicians participated in the online survey. Among total 33 self-reported questionnaires, twelve items were selected in this analysis. RESULTS: Rapid onset of action is the main influencing factor in selecting rescue opioids. Oral oxycodone (65%) and parenteral morphine (27%) are commonly used. A few physicians (3%) prefer to use transmucosal fentanyl. The percentage of physicians prescribing oral oxycodone due to its rapid onset of action is just 21.5%, whereas the percentage of physicians using parenteral morphine is 81.5%. Two thirds of respondents (66%) answered that breakthrough pain is not well controlled with rescue medications. CONCLUSION: There is a gap between the needs of physicians in terms of the perceived difficulties of managing breakthrough cancer pain and their practice patterns selecting rescue medications.

Association between Salivary Mitochondrial DNA Copy Number and Chronic Fatigue according to Combined Symptoms in Korean Adults / 가정의학회지

BACKGROUND: We examined the association between salivary mitochondrial DNA (mtDNA) copy number and chronic fatigue combined with depression and insomnia. METHODS: This cross-sectional study included 58 healthy adults with moderate to severe fatigue (Brief Fatigue Inventory [BFI] ≥4) for longer than 6 months. Subjects were classified as those without combined symptoms, with either depression (Beck Depression Inventory [BDI] ≥13) or insomnia (Pittsburgh Sleep Quality Index [PSQI] ≥5), or with both depression and insomnia. Salivary mtDNA copy number was measured by real-time quantitative polymerase chain reaction. The association was evaluated using a general linear model. RESULTS: About 76% of participants had either depression or insomnia as additional symptoms. These subjects were predominately female, drank more alcohol, and exercised less than those without combined symptoms (P<0.05). The group with both depression and insomnia exhibited significantly higher BFI and lower mtDNA copy number than those without combined symptoms (P<0.05). After adjusting for confounding factors, significant negative associations between mtDNA copy number and usual fatigue were found in the group without combined symptoms, whereas the negative associations in the group with combined symptoms were attenuated. BDI and PSQI were not associated with mtDNA copy number. CONCLUSION: Chronic fatigue is negatively associated with salivary mtDNA copy number. Salivary mtDNA copy number may be a biological marker of fatigue with or without combined symptoms, indicating that a separate approach is necessary.

Joint Effect of Cigarette Smoking and Body Mass Index on White Blood Cell Count in Korean Adults / 가정의학회지

BACKGROUND: White blood cell count is an independent risk factor for cardiovascular disease. Several lifestyle and metabolic factors such as cigarette smoking and obesity are known to be associated with an elevated white blood cell count. However, the joint effect of cigarette smoking and obesity on white blood cell count has not yet been fully described. METHODS: We explored the joint effect of cigarette smoking and obesity on white blood cell count using multiple logistic regression analyses after adjusting for confounding variables in a population-based, cross-sectional study of 416,065 Korean adults. RESULTS: Cigarette smoking and body mass index have a dose-response relationship with a higher white blood cell count, but no synergistic interaction is observed between them (men, P for interaction=0.797; women, P for interaction=0.311). Cigarette smoking and body mass index might have an additive combination effect on high white blood cell count. Obese male smokers were 2.36 times more likely and obese female smokers 2.35 times more likely to have a high white blood cell count when compared with normal body mass index non-smokers. CONCLUSION: Cigarette smoking and body mass index are independently associated with an elevated white blood cell count in both men and women.

Association between the Eating Family Meal and the Prevalence of Metabolic Syndrome Using Data from Korea National Health and Nutrition Examination Survey (2007–2012) / 가정의학회지

BACKGROUND: Several studies have shown that family meals promote a well-balanced and healthier diet and weight status. Metabolic syndrome is related to eating behavior. This study investigated the association between eating family meals and the prevalence of metabolic syndrome. METHODS: This cross-sectional study included 4,529 subjects who participated in the Korea National Health and Nutrition Examination Survey IV and V (2007–2012). A self-reported questionnaire was used to assess dietary status. Metabolic syndrome was defined according to the guidelines of the modified version of the National Cholesterol Education Program Adult Treatment Panel III. We compared the overall quality of dietary intake in family meal. RESULTS: Nutritional adequacy ratios for energy, protein, calcium, vitamin A, vitamin B₁, vitamin B₂, vitamin C, niacin, and potassium, and the mean adequacy ratio were significantly higher in the family meal group (P<0.05). The prevalence of metabolic syndrome was lower in the family meal group (P<0.05). However, we observed no significant association between eating family meals and the prevalence of metabolic syndrome. CONCLUSION: This study demonstrated that eating family meals appeared to be associated with nutrient adequacy. However, we observed no significant differences in prevalence of metabolic syndrome between the 2 groups.

Waist-to-Height Ratio as a Simple and Useful Indicator for Non-alcoholic Fatty Liver Disease in Korean Women

BACKGROUND: It has not been determined which obesity index might be most appropriate to predict nonalcoholic fatty liver disease in Asian populations. This study aimed to evaluate the usefulness of the waist-to-height ratio in assessing patients with nonalcoholic fatty liver disease and to identify the optimal cut-off values useful for predicting nonalcoholic fatty liver disease. METHODS: Receiver operating characteristic curve analyses were conducted in order to assess the accuracy of the waist circumference, body mass index, and waist-to-height ratio for detecting nonalcoholic fatty liver disease among 616 women aged 20 years or older. To evaluate the optimal value of anthropometric indices, the Youden J-index (sensitivity+specificity-1) was used. RESULTS: The area under the ROC curve of waist-to-height ratio was highest among anthropometric obesity indices as follows: 0.776 (0.731-0.822) for waist circumference, 0.775 (0.728-0.822) for body mass index, and 0.792 (0.748-0.836) for waist-to-height ratio, respectively. Using a waist-to-height ration cut-off value of 0.49, the sensitivity and specificity for detecting nonalcoholic fatty liver disease were 72.3 % and 74.7%, respectively. CONCLUSION: These results demonstrated that the waist-to-height ratio may be a better obesity index for identifying individuals at risk for nonalcoholic fatty liver disease in Korean women.

Factors Affecting Research Participation of Bereaved Families of Terminal Cancer Patients: A Prospective Preliminary Study / 한국호스피스완화의료학회지

PURPOSE: Little is known regarding the factors associated with the willingness of family caregivers of terminal cancer patients to participate in a bereaved survey. This study aimed to ascertain the pre-loss factors that predict actual participation in a bereaved survey. METHODS: We conducted a prospective observational study using data from two multi-center surveys at the end-of-life and after loss. In order to identify the pre-loss factors associated with participating in the bereaved survey, we used a step-wise multivariate logistic regression analysis. RESULTS: Among 185 bereaved individuals, 30 responded to the survey (response rate: 16.2%). There were differences between the participation group and the non-participation group regarding religion, economic status, and perceived quality of care as assessed by the Quality Care Questionnaire-End of Life. A final multivariate model revealed that bereaved individuals who professed a religion (adjusted odds ratio [aOR]=5.01; P=0.008), had a high income (aOR=4.86, P=0.003), and satisfied with the care for familial relationship (aOR=4.49, P=0.003) were more likely to engage in the bereaved survey. CONCLUSION: Our finding suggests that improving the quality of end-of-life care may promote actual participation in a bereaved survey through easing post-loss distress. More attention should also be paid to those bereaved individuals who are hesitant to participate in a bereaved survey.

Relationship between Blood Mercury Concentration and Bone Mineral Density in Korean Men in the 2008–2010 Korean National Health and Nutrition Examination Survey / 가정의학회지

BACKGROUND: The results of previous studies on the association between blood mercury (Hg) and bone mineral density (BMD) are inconsistent. We therefore used a large-scale nationwide representative sample of Korean men to investigate the relationship between these two parameters. METHODS: A nationwide cross-sectional study was conducted using data from the 2008 to 2010 Korean National Health and Nutrition Examination Survey to evaluate the relationship between blood Hg and BMD and the prevalence of osteopenia or osteoporosis in 1,190 men over 50 years of age. BMD was measured by dual-energy X-ray absorptiometry. Osteopenia and osteoporosis were diagnosed for each body site according to World Health Organization T-score criteria. RESULTS: After adjusting for age, body mass index, caloric energy and calcium intake, vitamin D levels, fish consumption, alcohol consumption, smoking, and exercise, quartiles of blood Hg were positively associated with femur neck T-scores in multiple linear regression analysis (β=0.06, P-value=0.03). Compared with the lowest blood Hg quartile, the odds ratios and 95% confidence intervals for diagnosis of osteopenia or osteoporosis in the second and fourth quartiles were 0.63 (0.41–0.99) and 0.57 (0.36–0.91), respectively, in the femur neck after adjusting for the same co-variables. CONCLUSION: High blood Hg levels were associated with reduced odds of decreased femur neck BMD in Korean men. However, subgroup analysis did not show a significant protective effect of blood Hg on osteoporotic fractures. Further research is necessary to clarify the association between blood Hg and BMD.

Management of long-term colorectal cancer survivors in Korea

Colorectal cancer (CRC) is the third most common cancer in Korea. Its average growth rate has been 3.7% annually from 1999 to 2013. The 5-year relative survival rate is 75.6%. The number of CRC survivors is expected to increase steadily because of its high incidence and survival rate. Because CRC survivors are at risk for recurrence, metachronous cancer, and other cancers, they should be checked regularly. Recommended surveillance includes history-taking and physical examination, colonoscopy, carcinoembryonic antigen testing, and computed tomography. Routine complete blood counts, liver function test, and positron emission tomography are not recommended. CRC survival, which is associated with Lynch syndrome and familial adenomatous polyposis, is also related to a higher risk of other cancers such as gastrointestinal and gynecologic cancers. Additional surveillance should be taken. CRC survivors could complain of general health problems such as cancer-related fatigue and psychosocial/cognitive dysfunction, in addition to treatment-related problems including bowel/urologic/sexual dysfunction, peripheral neuropathy, and ostomy care. They are also at greater risk of cardiovascular diseases. The primary care physician should counsel CRC survivors about their health problems and make an effort to address these concerns. Primary care physicians should try to communicate with CRC survivors and all specialists for clinical follow-up care.

Breakthrough Cancer Pain / 한국호스피스완화의료학회지

Breakthrough cancer pain is a transient exacerbation of pain that occurs despite relatively well controlled background pain with around-the-clock analgesia. It is highly prevalent in patients with cancer pain, with an overall prevalence of 70~90%. Breakthrough cancer pain has several negative effects on quality of life, including a decrease in functional status and social relationship, and higher incidence of anxiety/depression. It also places a detrimental burden on their families, society, and the healthcare system. According to the pathogenic mechanism, breakthrough cancer pain is classified into two categories: idiopathic (or spontaneous) pain and incident pain. Episodes of breakthrough cancer pain have typical characteristics, including rapid onset (5~10 min), severe intensity, and short duration (30~60 min). However, there are some variations in timing and severity of pain among patients and episodes. Therefore, a thorough assessment of pain episodes is needed and management plan must be individualized to provide optimal treatment. Several immediate-release formulations such as oxycodone, morphine, and hydromorphone are widely used despite relatively slow onset of action. Recent studies have shown that transmucosal fentanyl preparations were effective for faster control of breakthrough pain. We hope to improve management of breakthrough cancer pain with more efficient analgesics in line with currently available evidence.

High-Dose Vitamin C Promotes Regression of Multiple Pulmonary Metastases Originating from Hepatocellular Carcinoma

We report a case of regression of multiple pulmonary metastases, which originated from hepatocellular carcinoma after treatment with intravenous administration of high-dose vitamin C. A 74-year-old woman presented to the clinic for her cancer-related symptoms such as general weakness and anorexia. After undergoing initial transarterial chemoembolization (TACE), local recurrence with multiple pulmonary metastases was found. She refused further conventional therapy, including sorafenib tosylate (Nexavar). She did receive high doses of vitamin C (70 g), which were administered into a peripheral vein twice a week for 10 months, and multiple pulmonary metastases were observed to have completely regressed. She then underwent subsequent TACE, resulting in remission of her primary hepatocellular carcinoma.

Opioids use for chronic noncancer pain

The use of opioids for chronic noncancer pain has increased in recent years, although evidence for its long-term effectiveness is weak and its potential for harm is significant. Most reports suggest that chronic opioid therapy can be effective for the reduction of chronic pain and for the improvement of functioning and health-related quality of life. However, opioids are also associated with potentially serious harm including pharmacologic adverse effects and socioeconomic problems such as abuse, addiction, and diversion. Physicians should use a structured approach that includes a biopsychosocial evaluation and treatment plan that encourages patients to reach functional goals. There should be a comprehensive evaluation of the cause of pain, assessment for risk of opioid complications (including misuse and addiction), and a detailed treatment history including a review of medical records. Regular monitoring for safety and effectiveness is essential including regular checking of functional improvement and progress towards the pretreatment goals. Ineffective or unsafe opioid therapy should be promptly tapered or stopped. In Korea until now, there are no adequate recommendations for opioid prescription in the management of chronic noncancer pain. A Korean guideline or task force team should be established to provide personalized treatment for carefully selected and monitored patients.

Developing a Scoring Guide for the Appraisal of Guidelines for Research and Evaluation II Instrument in Korea: A Modified Delphi Consensus Process

Korea has a relatively short history in the development and use of clinical practice guidelines (CPGs). Additionally, it has been difficult to employ the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument due to the lack of consensus and the presence of differences in Korean medical settings and in the Korean socio-cultural environment. An AGREE II scoring guide was therefore developed to reduce differences among evaluators using the same tool. In consideration of the importance of using a quantitative measure of satisfaction with the elements described in the AGREE II manual, a final draft was developed through a Delphi consensus process. Ninety-two draft scoring guides for anchor points 1, 3, 5, and 7 (full score) in 23 items were developed. Consensus was defined as agreement among at least 70% of the raters. Agreement on 88 draft scoring guidelines was reached in the first Delphi round, and agreement for the remaining four was achieved in the second round. The development of an AGREE II scoring guide in this study is expected to contribute to improving the CPG environment.
