Genetic Diversity and Antibiotic Resistance Patterns of Staphylococcus Aureus Isolated from Leaf Vegetables in Korea.

Staphylococcus aureus is an important foodborne pathogen on global basis. The current study investigated the genetic patterns in S. aureus isolates from leaf vegetables (n = 53). Additional isolates from livestock (n = 31) and humans (n = 27) were compared with the leaf vegetable isolates. Genes associated with toxins, antibiotic resistance, and pulsed-field gel electrophoresis (PFGE) patterns were analyzed. At least 1 enterotoxin-encoding gene (sea, seb, sec, sed, and see) was detected in 11 of 53 (20.75%) leaf vegetable isolates. When the agr (accessory gene regulator) grouping was analyzed, agr II was the major group, whereas agr IV was not present in leaf vegetable isolates. All S. aureus isolates from leaf vegetables were resistant to more than one of the antibiotics tested. Nineteen of 53 (35.85%) isolates from leaf vegetables exhibited multidrug-resistance, and 11 of these were MRSA (methicillin-resistant S. aureus). A dendrogram displaying the composite types of S. aureus isolates from 3 origins was generated based on the combination of the toxin genes, agr genes, antibiotic resistance, and PFGE patterns. The isolates could be clustered into 8 major composite types. The genetic patterns of S. aureus isolates from leaf vegetables and humans were similar, whereas those from livestock had unique patterns. This suggests some S. aureus isolates from leaf vegetables to be of human origin.

Forecasting the future reimbursement system of Korean National Health Insurance: a contemplation focusing on global budget and Neo-KDRG-based payment systems.

With the adoption of national health insurance in 1977, Korea has been utilizing fee-for-service payment with contract-based healthcare reimbursement system in 2000. Under the system, fee-for-service reimbursement has been accused of augmenting national healthcare expenditure by excessively increasing service volume. The researcher examined in this paper two major alternatives including diagnosis related group-based payment and global budget to contemplate the future of reimbursement system of Korean national health insurance. Various literature and preceding studies on pilot project and actual implementation of Neo-KDRG were reviewed. As a result, DRG-based payment was effective for healthcare cost control but low in administrative efficiency. Global budget may be adequate for cost control and improving the quality of healthcare and administrative efficiency. However, many healthcare providers disagree that excess care arising from fee-for-service payment alone has led to financial deterioration of national health insurance and healthcare institutions should take responsibility with global budget payment as an appropriate solution. Dissimilar payment systems may be applied to different types of institutions to reflect their unique attributes, and this process can be achieved step-by-step. Developing public sphere among the stakeholders and striving for consensus shall be kept as collateral to attain the desirable reimbursement system in the future.

Causality analysis on health care evaluation criteria for state-operated mental hospitals in Korea using Malcolm Baldrige National Quality Award model.

Hospitals today are pressured to move away from the conventional health services management techniques and provide higher-quality health care to survive in intense competition. In our study, we aimed to develop health care evaluation criteria for the mental health care sector based on the existing Malcolm Baldrige National Quality Award model, and verify the causality of the evaluation model to lay groundwork for future research on the outcomes of national quality awards for mental health care. We focused on comparison groups comprising five state-operated mental hospitals in Korea using 92 survey questions derived from the MBNQA criteria for health care through structural equation modeling techniques. We verified that Leadership drives Foundation and Direction, which affect System that creates Results with 15 hypotheses supported out of 18 hypotheses established. We believe our findings will provide valuable implications to the top management of mental hospitals for self-examining quality management and promoting competitiveness.

A comprehensive model of factors affecting adoption of clinical practice guidelines in Korea.

This study aims to investigate the factors related to the adoption of clinical practice guidelines in clinical settings in Korea; it also aims to determine how these factors differ depending on the specific situation of health care system and professional climate. The research sample comprised physicians who are board members of academic societies with experiences in development of clinical practice guidelines using a convenient sampling. We analyzed 324 physicians with pooling two-year sample of 2007 and 2008. From all the respondents, 48.8% stated that they followed Clinical Practice Guidelines, and 93.4% agreed with the content in the Clinical Practice Guidelines. With regard to the item on the self-efficacy of practicing guidelines, 90.3% of the respondents selected 'low level'. In the regression analysis, the factors associated with implementation were level of recognition, agreement and self-efficacy and positive attitude towards practice guidelines. Although the health care system in Korea differs from those in Western countries, our results revealed that the factors related to the adoption of practice guidelines were similar to the research results of Western countries. These results suggest that professionals' attitudes towards clinical practice guidelines are universal, and implementation strategies should be developed globally.
