1.Establishment, Present Condition, and Developmental Direction of the New Korean Healthcare Accreditation System.
Journal of Korean Medical Science 2012;27(Suppl):S61-S69
On July 23rd, 2010 a revised medical law (Article 58) was passed to change existing evaluation system of medical institutions to an accreditation system. The new healthcare accreditation system was introduced to encourage medical institutions to work voluntarily and continuously to improve patient safety and medical service quality. Changes regarding the healthcare accreditation system included the establishment of an accreditation agency, the voluntary participation of medical institutions, accreditation standards centering on the treatment process and patient safety, tracing methodology, and the announcement of comprehensive results concerning accreditation. Despite varying views on the healthcare accreditation system, including some that are critical, it is meaningful that the voluntary nature of the system acknowledges that the medical institutions must be active agents in improving medical service quality. Healthcare quality is not improved instantaneously, but instead gradually through continuous communication within the clinical field. For this accreditation system to be successful, followings are essential: the accreditation agency becomes financially independent and is managed efficiently, the autonomy and regulation surrounding the system are balanced, the professionalism of the system is ensured, and the medical field plays an active role in the operation of the system.

Exercise is one of the most ubiquitous triggers of acute bouts of asthma. Late asthmatic responses(LARs) have been described following strenuous exercise, as in allergen-induced asthma. However, most studies have reported that airway responsiveness is not increased after exercise, even in subjects with LAR to exercise. This suggests that LAR after exercise may not be associated with inflammatory changes in the airways. We have frequently seen asthmatic children whose complaint is that symptoms are exacerbated at night after strenuous daytime exercise. Furthermore, airway responsiveness to allergen was reported to increase after LAR to exercise. Therefore, it is crucial to know whether exercise can induce airway inflammation, as in allergen-induced asthma. As an indirect measure to investigate it, we measured the activation status of eosinophil granulocyte in the peripheral blood during the early and late phase of exercise- or allergen-induced asthma. Eight subjects who showed early asthmatic response(EAR) and LAR(group 1), or EAR only (group 2) to allergen (Dermatophagoides pteronyssinus) challenge were selected. Similarly eight subjects who showed EAR and LAR(group 3), or EAR only (group 4) to exercise were selected. Blood samples were drawn at baseline, the early phase, the late phase, and 24 hours after each stimuli. Eosinofphil cationic protein (ECP) was measured in the serum. Eosinophil granulocytes were separated and the production of leukotriene C4 (LTC4) from purified eosinophfis was measured after stimulation with the calciumionophore. Serum levels of ECP were unchanged at EAR after allergen or exercise challenge. In the dual responder to allergen (group 1), serum ECP level was elevated at LAR and 24 hours after allergen challenge, as compared with the baseline level. On the other hand, in the dual responder to exercise (group 3), it remained unaltered up to 24 hours after exercise challenge. Eosinophils at EAR after allergen or exercise challenge in each group generated the similar amounts of LTC4 as baseline values. In group 1, the production of LTC4 was slightly increased though not significantly at LAR, and significantly increased 24 hours after allergen challenge. In group 3, it was increased significantly at LAR, but restored to the baseline values at 24 hours after exercise challenge. These results indicate that not only allergen but also exercise can activate eosinophils in accordance with LAR. The present findings suggest that LAR to exercise may also have the potential to induce airway eosinophilic inflammation although its duration may be shorter than that of LAR to allergen. Therefore exercise should be understood not only as a triggering factor of bronchoconstriction but also as one that incites or deteriorates airway inflammation.

OBJECTIVES: Although risk factors for coronary artery disease are also associated with increased carotid intima-media thickness (IMT), there is little information available on the asymptomatic, young adult population. We examined the association between multiple cardiovascular risk factors and the common carotid IMT in 280 young Korean adults. METHODS: The data used for this study was obtained from 280 subjects (130 men and 150 women) aged 25 years who participated in the Kangwha Study follow-up examination in 2005. We measured cardiovascular risk factors, including anthropometrics, blood pressure, blood chemistry, carotid ultrasonography, and reviewed questionnaires on health behaviors. Risk factors were defined as values above the sex-specific 75th percentile of systolic blood pressure, body mass index, total cholesterol/high-density lipoprotein cholesterol ratio, fasting blood glucose and smoking status. RESULTS: The mean carotid IMT+/-standard deviation observed was 0.683+/-0.079 mm in men and 0.678+/-0.067 mm in women (p=0.567) and the evidence of plaque was not observed in any individuals. Mean carotid IMT increased with an increasing number of risk factors(p for trend <0.001) and carotid IMT values were 0.665 mm, 0.674 mm, 0.686 mm, 0.702 mm, and 0.748 mm for 0, 1, 2, 3, and 4 to 5 risk factors, respectively. The odds ratio for having the top quartile carotid IMT in men with 3 or more risk factors versus 0-2 risk factors was 5.09 (95% CI, 2.05-12.64). CONCLUSIONS: Current findings indicate the need for prevention and control of cardiovascular risk factors in young adults and more focus on those with multiple cardiovascular risk factors.

PURPOSE: This study estimated the economic burden of cancer in Korea during 2000-2010 by cancer site, gender, age group, and cost component. MATERIALS AND METHODS: Data came from national health insurance claims data and information from Statistics Korea. Based on the cost of illness method, this study calculated direct, morbidity and mortality cost of cancer in the nation during 2000-2010 by cancer site, gender, and age group. RESULTS: With an average annual growth rate of 8.9%, the economic burden of cancer in Korea increased from 11,424 to 20,858 million US$ (current US dollars) during 2000-2010. Colorectal, thyroid, and breast cancers became more significant during the period, i.e., the 5th/837, the 11th/257, and the 7th/529 in 2000 to the 3rd/2,210, the 5th/1,724, and the 6th/1,659 in 2010, respectively (rank/amount in million US$ for the total population). In addition, liver and stomach cancers were prominent during the period in terms of the same measures, i.e., the 1st/2,065 and the 2nd/2,036 in 2000 to the 1st/3,114 and the 2nd/3,046 in 2010, respectively. Finally, the share of mortality cost in the total burden dropped from 71% to 51% in Korea during 2000-2010, led by colorectal, thyroid, breast, and prostate cancers during the period. These results show that the economic burden of cancer in Korea is characterized by an increasing importance of chronic components. CONCLUSION: Incorporation of distinctive epidemiological, sociocultural contexts into Korea's cancer control program, with greater emphasis on primary prevention such as sodium-controlled diet and hepatitis B vaccination, may be needed.

BACKGROUND: Treatment outcome with only chemotherapy for multi-drug resistant tuberculosis is usually considered not to be satisfactory. However, the combined therapy of chemotherapy with surgical treatment has been producing higher sputum AFB negative conversion and longer survival rates, and this treatment strategy is expected to be a set-up for the patients with multi-drug resistant tuberculosis. MATERIAL AND METHOD: A retrospective review was performed with the medical records and laboratory findings in 49 patients with multi-drug resistant tuberculosis of 130 patients who underwent pulmonary resection for pulmonary tuberculosis between January 1995 and December 1999 at National Masan Tuberculosis Hospital. RESULT: A mean number of the resistant drugs was 4.5 with a mean age of 35 years. Cavitary lesions on plain chest x-ray were shown in 43 patients of 49(87.8%). Thirty one had positive sputum cultures preoperatively(63.3%). Operative techniques were as follows; 12 pneumonectomies, 28 lobectomies, 7 lobectomies with segmentectomies or wedge resections, one wedge resection and a cavernoplasty. Sputum AFB negative conversion rate was 93.5 % with continuous postoperative chemotherapy. There was no death after operation. Air leakage over a week, postoperative bleeding and wound disruption were developed as postoperative complications. CONCLUSION: We experienced the higher effectiveness of postoperative chemotherapy with pulmonary resection on multi-drug resistant tuberculosis. Although there are several different ideas about operative indications, postoperative drug regimens and length of postoperative medications, pulmonary resection should be considered actively as a effective combination measure with chemotherapy to give a treatment for multi-drug resistant pulmonary tuberculosis.

OBJECTIVES: To estimate the annual socioeconomic costs of stroke in Korea in 2005 from a societal perspective. METHODS: We identified those 20 years or older who had at least one national health insurance (NHI) claims record with a primary or a secondary diagnosis of stroke (ICD-10 codes: I60-I69, G45) in 2005. Direct medical costs of the stroke were measured from the NHI claims records. Direct non-medical costs were estimated as transportation costs incurred when visiting the hospitals. Indirect costs were defined as patients' and caregivers' productivity loss associated with office visits or hospitalization. Also, the costs of productivity loss due to premature death from stroke were calculated. RESULTS: A total of 882,143 stroke patients were identified with prevalence for treatment of stroke at 2.44%. The total cost for the treatment of stroke in the nation was estimated to be 3,737 billion Korean won (KRW) which included direct costs at 1,130 billion KRW and indirect costs at 2,606 billion KRW. The per-capita cost of stroke was 3 million KRW for men and 2 million KRW for women. The total national spending for hemorrhagic and ischemic stroke was 1,323 billion KRW and 1,553 billion KRW, respectively, which together consisted of 77.0% of the total cost for stroke. Costs per patient for hemorrhagic and ischemic stroke were estimated at 6 million KRW and 2 million KRW, respectively. CONCLUSIONS: Stroke is a leading public health problem in Korea in terms of the economic burden. The indirect costs were identified as the largest component of the overall cost.

PURPOSE: To evaluate the clinical performance through the Korean Medical Licensing Examination clinical skills assessment (KMLE CSA) this survey was done. METHODS: A survey of 130 interns and residents (46 applicants and 84 non-applicants for the KMLE CSA) at a university hospital in Seoul was conducted in January and February 2012. The data were gathered using a structured and self-administered questionnaire. For the items that assessed the clinical performance of these subjects, we selected 15 items that are mostly frequently used by Delphi's technique, and difficult procedural skills based on the results of medical students' performance. We also used subcomponents of the clinical problems test of the KMLE CSA. RESULTS: The total score on the KMLE CSA improved by 1.33 points (a perfect score is 10), 1.49 points for procedural skills, and 0.84 points for clinical problems by multiple regression analysis. The variables that influenced clinical skills were sex (females had 0.86 more points than males), experience in military or public services (1.04 points higher than persons without experience), and type of school (graduates of medical school had 1.41 more points than graduates of professional graduate school). CONCLUSION: Implementation of the KMLE CSA improved the clinical performance of medical graduates.

OBJECTIVES: This study aims to evaluate and explain the socioeconomic inequalities of all-cause mortality after breast cancer surgery in South Korea. METHODS: This population based study included all 8868 females who underwent radical mastectomy for breast cancer between January 2002 and June 2003. Follow-up for mortality continued from January 2002 to June 2006. The patients were divided into 4 socioeconomic classes according to their socioeconomic status as defined by the National Health Insurance contribution rate. The relationship between socioeconomic status and all-cause mortality after breast cancer surgery was assessed using the Cox proportional hazards model with adjusting for age, the Charlson's index score, emergency hospitalization, the type of hospital and the hospital ownership. RESULTS: Those in the lowest socioeconomic status group had a significantly higher hazard ratio of 2.09 (95% CI =1.50 - 2.91) compared with those in the highest socioeconomic group after controlling for all the identifiable confounding variables. For all-cause mortality after radical mastectomy, all the other income groups showed significantly higher 3-year mortality rates than did the highest income group. CONCLUSIONS: The socioeconomic status of breast cancer patients should be considered as an independent prognostic factor that affects all-cause mortality after radical mastectomy, and this is possibly due to a delayed diagnosis, limited access or minimal treatment leading to higher mortality. This study may provide tangible support to intensify surveillance and treatment for breast cancer among low socioeconomic class women.

An alveolar soft part sarcoma(ASPS) is a rare malignant soft tissue tumor, which metastasizes to the lung, bone and brain. Recently, we encountered an unusual case of a metastatic ASPS to the bilateral breasts in a 27-year-old woman. She had undergone surgery for an ASPS in her right thigh two years ago, which metastasized to the breast on three occasions, 15 months, 20 months and two years after surgery.

Although endoscopic submucosal dissection (ESD) is widely accepted as a curative treatment method for early gastric cancer (EGC) worldwide, metachronous recurrence often occurs after ESD for EGC. However, there are insufficient data about the role of Helicobacter pylori (H. pylori) infection and other risk factors for recurrence. We aimed to compare the metachronous lesion in the H. pylori persistent group and the eradicated group, and to identify risk factors for metachronous lesion. We retrospectively analyzed 782 patients who underwent ESD between January 2008 and December 2013. We excluded patients with dysplasia or patients who were not tested for H. pylori infection. One hundred eighty-five patients were enrolled. We studied risk factors for recurrence, and used survival analysis to test. There were 24 patients with metachronous recurrence after ESD for EGC among the group. The incidence of metachronous gastric lesions after ESD for EGC developed more in the over 70-year-old group (P = 0.025) and more in the H. pylori persistent group (P = 0.008). In conclusion, H. pylori infection and old age are independent risk factors for metachronous gastric lesions after ESD in EGC.
