Objective: We aimed to identify the expectations and preferences for medication and medical decision-making in patients with major psychiatric disorders. Methods: A survey was conducted among patients with major psychiatric disorders who visited psychiatric outpatient clinics at 15 hospitals between 2016 and 2018 in Korea. The survey consisted of 12 questions about demographic variables and opinions on their expectations for medication, important medical decision-makers, and preferred drug type. The most preferred value in each category in the total population was identified, and differences in the preference ratio of each item among the disease groups were compared. Results: A total of 707 participants were surveyed. In the total population, patients reported high efficacy (44.01%±21.44%) as the main wish for medication, themselves (37.39%±22.57%) and a doctor (35.27%±22.88%) as the main decision makers, and tablet/capsule (36.16%±30.69%) as the preferred type of drug. In the depressive disorders group, the preference ratio of high efficacy was significantly lower, and the preference ratio of a small amount was significantly higher than that of the psychotic disorder and bipolar disorder groups. The preference ratio of a doctor as an important decision maker in the bipolar disorder group was higher compared to the other groups. Conclusion This study revealed the preference for medications and showed differences among patients with psychiatric disorders. Providing personalized medicine that considers a patient’s preference for the drug may contribute to the improvement of drug compliance and outcomes.

Purpose: This study aimed to compare the short-term outcomes and safety profiles of androgen-deprivation therapy (ADT)+abiraterone/prednisone with those of ADT+docetaxel in patients with de novo metastatic hormone-sensitive prostate cancer (mHSPC). Materials and Methods: A web-based database system was established to collect prospective cohort data for patients with mHSPC in Korea. From May 2019 to November 2022, 928 patients with mHSPC from 15 institutions were enrolled. Among these patients, data from 122 patients who received ADT+abiraterone/prednisone or ADT+docetaxel as the primary systemic treatment for mHSPC were collected. The patients were divided into two groups: ADT+abiraterone/prednisone group (n=102) and ADT+docetaxel group (n=20). We compared the demographic characteristics, medical histories, baseline cancer status, initial laboratory tests, metastatic burden, oncological outcomes for mHSPC, progression after mHSPC treatment, adverse effects, follow-up, and survival data between the two groups. Results: No significant differences in the demographic characteristics, medical histories, metastatic burden, and baseline cancer status were observed between the two groups. The ADT+abiraterone/prednisone group had a lower prostate-specific antigen (PSA) progression rate (7.8% vs. 30.0%; p=0.011) and lower systemic treatment discontinuation rate (22.5% vs. 45.0%; p=0.037). No significant differences in adverse effects, oncological outcomes, and total follow-up period were observed between the two groups. Conclusions ADT+abiraterone/prednisone had lower PSA progression and systemic treatment discontinuation rates than ADT+docetaxel. In conclusion, further studies involving larger, double-blinded randomized trials with extended follow-up periods are necessary.

Objectives: Deliberate self-poisoning (DSP) is the most common suicide method and can be life-threatening. The purpose of this study was to investigate the factors related to the lethality of DSP and the characteristics of the adolescent group. Methods: A retrospective study was conducted on patients who had visited an academic hospital’s regional emergency medical center between 2015 and 2018. The data reviewed through their medical records included sociodemographic factors, clinical variables, and psychiatric treatment. Four groups (Q1–Q4) were categorized by descriptive analysis using the risk-rescue rating scale. Results: A total of 491 patients were enrolled in this study. This study showed that high lethality had statistically significant associations with male sex, older age, admitting suicidal intentions, and the use of herbicides for suicide. Logistic regression analyses showed a significant association between high-lethality and female [odds ratio (OR)=0.50, 95% confidence interval (CI)=0.30–0.81, p=0.01], non-psychiatric drugs (over-the-counter drug: OR=2.49, 95% CI=1.08–5.74, p=0.03; herbicide: OR=8.65, 95% CI=3.91–19.13, p<0.01), and denial of suicide intent (OR=0.28, 95% CI=0.15–0.55, p<0.01). Conclusion This study showed the clinical factors associated with the high lethality of DSP and suggested that efforts were needed to care for and thoroughly examine patients with DSP.

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.

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.

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.

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: We aimed to estimate the annual socioeconomic burden of coronary heart disease (CHD) in Korea in 2005, using the National Health Insurance (NHI) claims data. METHODS: A prevalence-based, top-down, cost-of-treatment method was used to assess the direct and indirect costs of CHD (International Classification of Diseases, 10th revision codes of I20-I25), angina pectoris (I20), and myocardial infarction (MI, I21-I23) from a societal perspective. RESULTS: Estimated national spending on CHD in 2005 was 2.52 billion dollar . The majority of the spending was attributable to medical costs (53.3%), followed by productivity loss due to morbidity and premature death (33.6%), transportation (8.1%), and informal caregiver costs (4.9%). While medical cost was the predominant cost attribute in treating angina (74.3% of the total cost), premature death was the largest cost attribute for patients with MI (66.9%). Annual per-capita cost of treating MI, excluding premature death cost, was 3183 dollar, which is about 2 times higher than the cost for angina (1556 dollar). CONCLUSIONS: The total insurance-covered medical cost (1.13 billion dollar) of CHD accounted for approximately 6.02% of the total annual NHI expenditure. These findings suggest that the current burden of CHD on society is tremendous and that more effective prevention strategies are required in Korea.

PURPOSE: Few studies have reported ovarian cancer risks in Korean patients with the BRCA1/2 mutation. We investigated the prevalence of ovarian cancer in Korean women at high risk for hereditary breast-ovarian cancer (HBOC) syndrome and reviewed the clinicopathological factors of ovarian cancer. METHODS: Female subjects who were enrolled in the Korean Hereditary Breast Cancer study were included. The questionnaire included a personal and family history of cancer. The BRCA1/2 mutation and CA-125 level were tested at the time of enrollment. A transvaginal ultrasonogram (TVUS) was recommended for subjects with an elevated CA-125 level. RESULTS: A total of 1,689 patients were included. No ovarian cancer was newly diagnosed by CA-125 level or TVUS during the enrollment. The prevalence of ovarian cancer was 1.71% in BRCA1/2 mutation carriers and 0.39% in non-carriers. Among 11 patients with ovarian cancer, five had the BRCA1 mutation and one had the BRCA2 mutation. The most common histopathological type was serous cystadenocarcinoma. No difference in clinicopathological findings between BRCA1/2 mutation carriers and non-carriers was observed. CONCLUSION: The prevalence of ovarian cancer was 58-fold elevated in women at high-risk for HBOC syndrome and 146-fold elevated in the BRCA1 subgroup, compared with the Korean general population. Further investigation with a long-term follow-up is required to evaluate BRCA1/2 gene penetrance.

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.
