Comparison of Clinical Outcomes between Plastic Stent and Novel Lumen-apposing Metal Stent for Endoscopic Ultrasound-Guided Drainage of Peripancreatic Fluid Collections

BACKGROUND/AIMS: Endoscopic ultrasound (EUS)-guided transmural drainage for peripancreatic fluid collections (PFCs) has gained wide acceptance as a nonsurgical intervention. Although a lumen-apposing metal stent (LAMS) was recently introduced, there are few data comparing the clinical outcomes between LAMS and plastic stent (PS) drainage. METHODS: Endoscopy databases of all patients who had undergone EUS-guided drainage for PFCs were searched and the clinical outcomes of EUS-guided drainage according to stent-type used were compared. RESULTS: A total of 27 patients (median age, 56 years) with PFCs underwent EUS-guided transmural drainage between January 2011 and December 2017. Of these, 17 underwent PS placement and 10 underwent LAMS placement. There was no significant difference in the technical success rate between the 2 groups (94.1% vs. 100%, p=1.0). Procedure time was shorter in the LAMS group compared to that in the PS group (10.6±2.5 min vs. 21.4±9.5 min, p=0.002). Among subjects with clinical success, recurrence of PFC after stent removal occurred in 5 of 12 patients with PS and 4 of 10 with LAMS, without statistical difference (41.7% vs. 40.0%, p=1.0). CONCLUSIONS: Although our study showed similar clinical outcomes for LAMS and PS, further prospective trials are required to validate the superiority of LAMS.

Comparison of Visceral Adiposity Index and Chinese Visceral Adiposity Index for Coronary Artery Calcification in Korean Adults

BACKGROUND: Visceral adiposity index (VAI) was developed to estimate visceral fat, and its association with various diseases including cardiovascular disease, insulin resistance, and fatty liver has been revealed. The Chinese VAI (CVAI) has been newly developed in China. This study aimed to compare the VAI and CVAI for coronary artery calcification by using the coronary artery calcium score (CACs)-a predictable index of asymptomatic atherosclerosis.METHODS: We conducted a cross-sectional study that included 66,011 participants (76.3% male and 23.7% female participants) visiting an university hospital for medical check-ups between January 2014 and December 2016. A receiver operating characteristic curve analysis was performed and the area under the curve (AUC) was calculated to compare the concordance of the CACs and the VAI, CVAI, waist circumference, body mass index, triglycerides, and high-density lipoprotein cholesterol.RESULTS: In all participants, the AUC for the CVAI was the largest, while that for the VAI was fourth among all the indices (AUC(CVAI)=0.653, AUC(VAI)=0.592). The AUC for the CVAI was the largest among the indices in both sexes (female AUC(CVAI)=0.77, male AUC(CVAI)=0.592), while that for the VAI was the second largest (female, AUC(CVAI) 0.771>AUC(VAI) 0.651; male, AUC(CVAI) 0.592>AUC(VAI) 0.564).CONCLUSION: In conclusion, the CVAI showed a higher degree of concordance with CACs, which is an indirect indicator of cardiovascular disease, than the VAI in Korean adults.

Combined Use of Neutrophil to Lymphocyte Ratio and C-Reactive Protein Level to Predict Clinical Outcomes in Acute Myocardial Infarction Patients Undergoing Percutaneous Coronary Intervention

BACKGROUND AND OBJECTIVES: Both neutrophil to lymphocyte ratio (NLR) and C-reactive protein (CRP) are biomarkers associated with poor prognosis of patients with acute myocardial infarction (AMI). However, the combined usefulness of NLR and CRP in predicting adverse outcomes has not been investigated. SUBJECTS AND METHODS: We analyzed 381 consecutive AMI patients who underwent percutaneous coronary intervention (PCI) from January 2012 to January 2014. The endpoints were all-cause mortality, recurrent myocardial infarction (MI), stent thrombosis, repeat revascularization, stroke, and major adverse cardiac and cerebrovascular events (MACCE) at 2-year follow-up. Included patients were divided into 4 groups according to the optimal cut-off values for NLR and CRP on receiver operating characteristic analysis predicting mortality. RESULTS: Patients with both high NLR (>6.30) and high CRP (>0.76) had significantly greater risk of all-cause death and MACCE at 24 months, with no significant increase in the risk of recurrent MI, stent thrombosis, or stroke compared with patients with either low NLR or low CRP, as well as those with low NLR and low CRP. Kaplan-Meier analysis revealed significantly lower survival in patients with high NLR-CRP. On Cox multivariate analysis, high NLR-CRP (hazard ratio 23.172, 95% confidence interval 6.575 to 81.671, p<0.001) was an independent predictor of all-cause death. CONCLUSION: Elevated levels of both NLR and CRP are associated with increased risk of long-term mortality in AMI patients who have undergone PCI.

The Association between Frailty and Cognition in Elderly Women / 가정의학회지

BACKGROUND: Frailty refers to the loss of physiologic complexity and the associated decline in ability to withstand stressors as one gets older. It is defined as unintentional weight loss, exhaustion, weakness, slow walking speed, and low physical activity. According to several western studies, frailty is associated with cognitive impairment, but there have been few studies about the relationship between frailty and cognitive impairment in Korea. Thus, the purpose of this study is to analyze the relationship between cognition and factors related to frailty such as grip strength, walking speed, physical activity, and depression, among female patients older than 65 in Korea. METHODS: A total of 121 subjects among the outpatients of the department of family medicine at Kangbuk Samsung Hospital who did not meet the exclusion criteria were included in this study. We divided the participants into 2 groups, according to the Korean version of the Montreal Cognitive Assessment (MoCA) score: 1 group with subjects that had normal cognition and the other group with patients that had impaired cognition. A comparison was made between the 2 groups in regards to the factors related to frailty, and we completed equation that predicting cognition from the frailty related factors. RESULTS: Compared with the impaired cognition group, the subjects in the normal cognition group had higher hand strength, and walked faster (P<0.001). There was no statistically significant difference in physical activity between the 2 groups (P=0.19). When multiple linear regression analysis was performed using age, grip strength, and walking speed as the predictor variables and MoCA score as the dependent variable, the regression coefficients were calculated to be: -0.2015, 0.2294, 1.2372, and -0.1436, respectively (P<0.05). CONCLUSION: In Korean female patients who are older than 65 years of age, cognition tends to decline as grip strength decreases, walking speed gets slower, depression becomes more severe, and as age increases.

Diagnostic Performance of Intravascular Ultrasound-Derived Minimal Lumen Area to Predict Functionally Significant Non-Left Main Coronary Artery Disease: a Meta-Analysis

BACKGROUND AND OBJECTIVES: Intravascular ultrasound (IVUS)-guided percutaneous coronary intervention frequently results in unnecessary stenting due to the low positive predictive value of IVUS-derived minimal lumen area (MLA) for identification of functionally significant coronary stenosis. We appraised the diagnostic accuracy of IVUS-derived MLA compared with the fractional flow reserve (FFR) to assess intermediate coronary stenosis. SUBJECTS AND METHODS: We searched MEDLINE and Cochrane databases for studies using IVUS and FFR methods to establish the best MLA cut-off values to predict significant non-left main coronary artery stenosis. Summary estimates were obtained using a random-effects model. RESULTS: The 17 studies used in our analysis enrolled 3920 patients with 4267 lesions. The weighted overall mean MLA cut-off value was 2.58 mm². The pooled MLA sensitivity that predicted functionally significant coronary stenosis was 0.75 (confidence interval [CI]: 0.72 to 0.77) and the specificity was 0.66 (CI: 0.64 to 0.68). The positive likelihood ratio (LR) was 2.33 (CI: 2.06 to 2.63) and LR (-) was 0.33 (CI: 0.26 to 0.42). The pooled diagnostic odds ratio (DOR) was 7.53 (CI: 5.26 to 10.76) and the area under the summary receiver operating characteristic curve for all the trials was 0.782 with a Q point of 0.720. Meta-regression analysis demonstrated that an FFR cut-off point of 0.75 was associated with a four times higher diagnostic accuracy compared to that of 0.80 (relative DOR: 3.92; 95% CI: 1.25 to 12.34). CONCLUSION: IVUS-derived MLA has limited diagnostic accuracy and needs careful interpretation to correlate with functionally significant non-left main coronary artery stenosis.

Development of the Perceived Stress Inventory: A New Questionnaire for Korean Population Surveys / 가정의학회지

BACKGROUND: Given emerging evidence of the association between stress and disease, practitioners need a tool for measuring stress. Several instruments exist to measure perceived stress; however, none of them are applicable for population surveys because stress conceptualization can differ by population. The aim of this study was to develop and validate the Perceived Stress Inventory (PSI) and its short version for use in population surveys and clinical practice in Korea. METHODS: From a pool of perceived stress items collected from three widely used instruments, 20 items were selected for the new measurement tool. Nine of these items were selected for the short version. We evaluated the validity of the items using exploratory factor analysis of the preliminary data. To evaluate the convergent validity of the PSI, 387 healthy people were recruited and stratified on the basis of age and sex. Confirmatory analyses and examination of structural stability were also carried out. To evaluate discriminatory validity, the PSI score of a group with depressive symptoms was compared with that of a healthy group. A similar comparison was also done for persons with anxious mood. RESULTS: Exploratory factor analysis supported a three-factor construct (tension, depression, and anger) for the PSI. Reliability values were satisfactory, ranging from 0.67 to 0.87. Convergent validity was confirmed through correlation with the Perceived Stress Scale, Center for Epidemiologic Studies Depression Scale, and State-Trait Anxiety Inventory. People with depressive or anxious mood had higher scores than the healthy group on the total PSI, all three dimensions, and the short version. CONCLUSION: The long and short versions of the PSI are valid and reliable tools for measuring perceived stress. These instruments offer benefits for stress research using population-based surveys.

Stroke in a Young Individual with Left Ventricular Noncompaction and Left Atrium Standstill

Isolated left ventricular noncompaction (LVNC) is a rare cardiomyopathy with morphologic characteristics of two distinct myocardial layers i.e., thin compacted epicardial and thick noncompacted endocardial layers. The noncompacted myocardium consists of prominent ventricular trabeculae and deep intertrabecular recesses. It can lead to arrhythmias, heart failure or systemic embolisms. Electrocardiographic patterns of patients with LVNC are various and non-specific; however, the most common findings are intraventricular conduction delay, left ventricular hypertrophy, and repolarization abnormalities. We reported the first case, to the best of our knowledge, of a 29-year-old man who had recent cerebral infarction and incidental LVNC with spontaneous left atrial standstill.

Clinical Significance of Non-Alcoholic Fatty Liver Disease as a Risk Factor for Prehypertension

Previous epidemiologic studies have shown the clinical association between non-alcoholic fatty liver disease (NAFLD) and cardiovascular disease (CVD). However, there is only limited information about the effect of NAFLD on the development of hypertension. Accordingly, we investigated the clinical association between NAFLD and prehypertension. A prospective cohort study was conducted on the 11,350 Korean men without prehypertension for 5 yr. The incidences of prehypertension were evaluated, and Cox proportional hazard model was used to measure the hazard ratios (HRs) for the development of prehypertension according to the degree of NAFLD (normal, mild, moderate to severe). The incidence of prehypertension increased according to NAFLD states (normal: 55.5%, mild: 63.7%, moderate to severe: 70.3%, P<0.001). Even after adjusting for multiple covariates, the HRs (95% confidence interval) for prehypertension were higher in the mild group (1.18; 1.07-1.31) and moderate to severe group (1.62; 1.21-2.17), compared to normal group, respectively (P for trend <0.001). The development of prehypertension is more potentially associated with the more progressive NAFLD than normal and milder state. These findings suggest the clinical significance of NAFLD as one of risk factors for prehypertension.

Clinical significance of nuclear factor kappaB and chemokine receptor CXCR4 expression in patients with diffuse large B-cell lymphoma who received rituximab-based therapy

BACKGROUND/AIMS: This study investigated the expression of nuclear factor kappaB (NF-kappaB) and the chemokine receptor (CXCR4) in patients with diffuse large B-cell lymphoma (DLBCL) who received rituximab-based therapy. METHODS: Seventy patients with DLBCL and treated with rituximab-CHOP (R-CHOP) were included, and immunohistochemistry was performed to determine the expression of NF-kappaB (IkappaB kinase alpha, p50, and p100/p52) and CXCR4. To classify DLBCL cases as germinal center B-cell-like (GCB) and non-GCB, additional immunohistochemical expression of CD10, bcl-6, or MUM1 was used in this study. The expression was divided into two groups according to the intensity score (negative, 0 or 1+; positive, 2+ or 3+). RESULTS: The median age of the patients was 66 years (range, 17 to 87), and 58.6% were male. Twenty-seven patients (38.6%) had stage III or IV disease at diagnosis. Twenty-three patients (32.9%) were categorized as high or high-intermediate risk according to their International Prognostic Indexs (IPIs). The overall incidence of bone marrow involvement was 5.7%. Rates of positive NF-kappaB and CXCR4 expression were 84.2% and 88.6%, respectively. High NF-kappaB expression was associated with CXCR4 expression (p = 0.002), and 56 patients (80.0%) showed coexpression. However, the expression of NF-kappaB or CXCR4 was not associated with overall survival and EFS. On multivariate analysis that included age, gender, performance status, stage, and the IPI, no significant association between the grade of NF-kappaB or CXCR4 expression and survival was observed. CONCLUSIONS: The current study suggests that the tissue expression of NF-kappaB and CXCR4 may not be an independent prognostic marker in DLBCL patients treated with R-CHOP.

Measuring stress with questionnaires

Stress is an area of research that has grown and diversified enormously since the early work of W. E. Cannon and Hans Selye. This development has been accompanied by an accelerated and renewed interest in instruments for evaluating stress and related factors. At present, the questionnaire method is the most popular for stress measurement. However, there is no consensus on how to measure stress because of the diverse scope of stress dynamic. There are many different kinds of questionnaires for measuring stress. And these questionnaires are different according to the various aspects, such as external stressors, individual's sense of control or coping, susceptibility, personality type, and subjective symptoms. Each questionnaire has its own drawbacks as a tool for measuring stress. Therefore choosing the appropriate instruments for evaluating stress objectively is a basic and crucial step for developing effective stress reduction strategies. Another important problem is that many of the questionnaires for measuring stress currently used in the field lack an appropriate cross-cultural adaptation process for the translated version and sufficient evidence of validity and reliability.

Feasibility of Non-TBI Conditioning with Busulfan and Fludarabine for Allogeneic Stem Cell Transplantation in Lymphoid Malignancy

BACKGROUND/AIMS: This retrospective study evaluated the transplantation outcomes of patients with adult lymphoid malignancies who received chemotherapy-based conditioning with busulfan and fludarabine (BuFlu) and busulfan and cyclophosphamide (BuCy2). METHODS: Thirty-eight patients (34 with acute lymphoblastic leukemia and 4 with lymphoblastic lymphoma) were included in the current study. The conditioning regimen was BuCy2 for 14 patients and BuFlu for the remaining 24 patients. Eight and 13 patients were high risk disease in the BuCy2 and BuFlu groups, respectively. RESULTS: The cumulative incidence of grade II-IV acute graft-versus-host disease (GVHD) was 56.5% and 55.2% and that of extensive chronic GVHD 17.0% and 55.6% (p = 0.018) for the BuFlu and BuCy2 groups, respectively. The 3-year relapse rate was 27.8% and 31.4% and 3-year overall survival 34.3% and 46.8% for the BuFlu and BuCy2 groups, respectively. Treatment-related mortality (TRM) was significantly lower in the BuFlu group (16.9%) than in the BuCy2 group (57.1%, p = 0.010). In multivariate analyses, the BuFlu regimen was identified as an independent favorable risk factor for TRM (hazard ratio [HR], 0.036; p = 0.017) and extensive chronic GVHD (HR, 0.168; p = 0.034). CONCLUSIONS: Our BuFlu regimen would appear to be an acceptable conditioning option for lymphoid malignancies, including high-risk diseases. It was safely administered with a lower TRM rate than BuCy2 conditioning.

Clinical Characteristics of Patients with Medically Unexplained Chronic Widespread Pain: A Primary Care Center Study / 가정의학회지

BACKGROUND: Chronic widespread pain (CWP) is known as a common symptom of several organic and psychological disorders. Although medically unexplained CWP (MUE) has lots of clinical distress symptoms, there were no distinct symptoms or signs. Therefore, we conducted this study to investigate clinical distress symptoms of MUE distinct from those of medically explained CWP (ME). METHODS: One hundred nine patients with CWP were enrolled in the study. We classified the study subjects into three groups depending on their medical problems associated with CWP: organic group (ORG), psychological group (PSY), and MUE. All subjects were asked to fill out self-report questionnaires consisting of clinical distress scales including the Korean version of the Fibromyalgia Impact Questionnaire (FIQ-K), fatigue scale, depression scale, and stress scale. And physicians examined 18 tender points over their entire body of the subjects. RESULTS: MUE patients had higher FIQ-K and fatigue severity scores than ORG patients (all P < 0.05). The average number of tender points were 11.33 in MUE patients, 6.48 in ORG patients and 5.02 in PSY patients and statistically significant (P < 0.0001). There were no statistically different factors between MUE and PSY patients with exception for the number of tender points. Depressive symptom was the highest in PSY patients but not statistically different from MUE patients. CONCLUSION: MUE patients had higher physical impairments, fatigue severity and more number of tender points than ORG patients, but had no different clinical characteristics from PSY patients except for the number of tender points.

A Randomized Controlled Trial of SMS Text Messaging versus Postal Reminder to Improve Attendance after Lipid Lowering Therapy in Primary Care / 가정의학회지

BACKGROUND: In the primary care setting, compliance with lipid lowering therapy was relatively low. In order to compare the efficacy of a short messaging service (SMS) text messaging and postal reminder as means of improving attendance rates during the first 24 weeks of lipid-lowering therapy, a randomized controlled trial of 918 patients from 19 family practice clinics was conducted between February 2003 and June 2006. METHODS: Patients were randomly assigned into 3 groups: SMS (327), postal (294),and control (297) group. To ascertain attendance rates, patients were followed up at 24 weeks after their treatment. Reminders were sent at 16 weeks from the coordinating center. RESULTS: Overall attendance rate was 74.1%. This differed between groups, with 76.1% attendance for the SMS group, 73.5% for the postal group, and 72.4% for the control group. According to a multivariate analysis, the SMS group had a significantly higher attendance rate (Odds ratios [OR] 1.48; 95% confidence interval [CI], 1.01 to 2.16) than the control group, but the postal group (OR, 1.15; 95% CI, 0.79 to 1.69) did not. Moreover, the cost per attendance for the SMS reminder (155 Korean Won [KRW]) was much lower than that for the postal reminder (722 KRW). CONCLUSION: SMS reminder may be more cost saving method to improve the attendance rate compared with the postal reminder.

Patterns of Complementary and Alternative Medicine Therapies in Patients with Chronic Fatigue or Pain / 가정의학회지

BACKGROUND: It is well-known that patients with chronic fatigue or frequent pain seek complementary and alternative medicine therapies (CAT) in Western countries. We conducted this study to determine the pattern of CAT use and the factors related to CAT use in patients with chronic fatigue or pain in Korea. METHODS: This was a cross-sectional study. The participants (n = 143) with chronic fatigue or pain completed a self-reported questionnaire including demographic characteristics and lifestyle as well as disease-related and CAT-related items. RESULTS: The frequency of CAT use was 51.0& and 39.2& over the past 10 years and 1 year, respectively. The most common type of CAT used was herbal medicine. The therapeutic effects of the CAT were similar to physicians' prescriptions. CAT were most often used in combination with conventional medicine rather than alone. More than 70.0& of subjects did not consult their physicians for the use of CAT. The duration of illness, severity of fatigue and pain was signifi cantly related to the use of CAT. CONCLUSION: Many patients with chronic fatigue or pain use CAT. Most of these patients do not consult their physicians regarding CAT use.

Perception and Experience of CAM Education for Family Practice Residents by Family Practice Training Faculty in South Korea

BACKGROUND: Complementary and alternative medicine (CAM) use is popular and current trend suggests a demand for CAM education during residency training. Our objective was to assess perception, the need and experience of CAM education for family practice residents by training faculty. METHODS: A questionnaire was administered to family physicians (n=262) who were registered in the Korean Academy of Family Medicine as residency training faculty between February and May 2006. RESULTS: One hundred and seven (40.8%) of 262 faculty completed the questionnaires. Eighty three (77.6%) respondents recognized the need of CAM education during residency training and fifty two (46.8%) respondents have already educated some kind of CAM. Thirty nine (36.4%) respondents replied that partial CAM educational contents were given out at conferences. Seventy eight (72.9%) respondents recognized the need for educating residents on the general outlines of CAM along with education on verified CAM. Sixty six (61.7%) respondents replied that the Korean Academy of Family Medicine should host such education. CONCLUSION: Most family practice training faculty recognized the need for providing CAM education for family practice residents during residency training, but about an half of family practice training faculty did not have experiences of CAM education.

Colorectal Cancer Screening Recommendations by Primary Care Physicians' in Seoul

BACKGROUND: Regular colorectal cancer (CRC) screening is known to reduce the CRC incidence and mortality. Health care providers can play a key role in recommending screening to healthy people. However, data on providers' CRC screening knowledge, attitude, and practice are sparse in Korea. We investigated primary care physicians' perception and performance of practice guidelines for CRC screening recommendations, and their view of barriers to physicians' adherence to guidelines. METHODS: A questionnaire was administered to 760 primary care physicians of internal medicine, general surgery, and family medicine in Seoul, Korea. The data were collected from March 2 to April 30, 2004, and those of 106 respondents (response rate 14%) were analyzed. RESULTS: Forty seven percent of respondents reported they recommended CRC screening. The most common screening test equipment in primary care settings was the fecal occults blood test (22.6%) followed by sigmoidoscopy (16.0%), colonoscopy (16.0%), and double contrast barium enema (10.4%). However, colonoscopy was recommended the most as a CRC screening method (54%) and only 43% of respondents complied with the interval indicated on the guidelines. Awareness (64.8%) and agreement (93.2%) to CRC screening recommendation by primary care physicians in Seoul, Korea was high, but the screening delivery was suboptimal. Many primary care physicians regarded patient-related factors were more important barriers of CRC screening than environment-related factors. CONCLUSION: There were many barriers to physicians' guideline adherence. It may be useful to develop and improve guidelines in considerationt these barriers to establish appropriate cancer screening.

Factors Related to Increase of Blood Pressure in Obese Children and Adolescents

Background: As obese population is increasing nowadays, research on blood pressure of obese children is being performed more frequently. However, there are only few research related to factors about blood pressure among obese children in Korea. The purpose of this study was to analyze the factors affecting blood pressure of obese children and adolescents. Methods: The subjects were elementary and middle school students diagnosed with obesity (n=1716). Height, weight, waist circumstance, body fat percent, blood pressure were measured. Family history and sexual maturity were investigated through the questionnaire. The relationship between the factors and the increase of blood pressure was analyzed. Results: Body weight was the most powerful factor among to factors related to increase of blood pressure (male r=0.45, P<0.05, female r=0.37, P<0.05). Also, height, percentage weight for height (PWH), body mass index (BMI) and waist circumference was correlated with the blood pressure. In multiple regression analysis, family history of hypertension and the sexual maturity were significant determinants of blood pressure in males after adjusting for weight. However, body fat percent was a significant determinant in females. Conclusion: Body weight was the most important factor which increased the blood pressure in obese children and adolescents in both sexes. But males and females had different factors related to the increase of blood pressure with the exception of body weight.

The Current Educational Measurement of Family Practice Residents

BACKGROUND: The educational assessment of residents is very important in order to check their knowledge and to improve their ability. In case of family practice, the residents spend most of their training time in outside rotations with other specialities. Therefore, they are requested to be evaluated by each specialist after each rotation. To give more accurate assessment, we surveyed directly our family practice residents and family practice faculties. METHODS: A questionnaire was sent to family practice residents and family practice faculties in 116 hospitals from May to June 2006. The response rate was 29% and 78%, respectively. RESULTS: Among the total, 70.2% of family practice residents thought an assessment is necessary, but only 51.7% were evaluated. Overall, 90.4% of family practice faculties knew about the assessment of residents made by other specialists, and only 56.7% of faculties requested other specialists to assess their family practice residents. CONCLUSION: Most of the family practice residents and their faculties knew the need for assessment, but they complained there were no objectivity and the assessment tool was lacking. In order to solve this problem, it is urgent to develop a unified form and guidelines of assesment.

Curriculum and Training Difficulties of Family Medicine Residency Programs in Korea

BACKGROUND: This study was conducted to survey the current status of family medicine residency programs and to evaluate the difficulties in training of the curriculums. METHODS: Questionnaires on residency programs were sent to all the centers of residency programs by mail in April 2006. The questionnaire included detailed characteristics of residency programs, curriculum schedule, reasons for failed specific curriculum, and review and measures by the program center and the Korean Academy of Family Medicine to resolve problematic curriculums. RESULTS: A total of 113 residency programs responded. Among the 93 residency programs except for the 20 subsidiary hospitals, inadeguate subjects were mainly dermatology (12 programs, 12.3%), psychiatry (6 programs, 7.5%), ophthalmology (5 programs, 7.1%), and otolaryngology (5 programs, 7.1%). Training rejection rate was higher in dermatology (13 programs, 14.4%), radiology (11 programs, 13.1%), gastrofibroscopy (8 programs, 9.5%), and psychiatry (5 programs, 6.2%). Emergency me-dicine in 4 programs and general surgery in 3 programs had a longer duration of training than initially planned. Difficulties in training some subjects were due to failed establishment of specific curriculums in non-university hospital. Commonly established clinics were health promotion center, obesity clinic, smoking cessation clinic, geriatric clinic, stress clinic, and clinical nutrition clinic. Family medicine center programs included gastrofibroscopy, obesity, smoking cessation, geriatrics, hospice care, and evidence-based medicine. CONCLUSION: There is repeated demand for taking measures to promote better curriculum in the nation-wide view of family medicine. Dermatology, radiology, psychiatry, and otolaryngology were the subjects difficult to receive training. Measures to strengthen the weak subjects are urgently needed.
