Development of Models for Regional Cardiac Surgery Centers.

Background: This study aimed to develop the models for regional cardiac surgery centers, which take regional characteristics into consideration, as a policy measure that could alleviate the concentration of cardiac surgery in the metropolitan area and enhance the accessibility for patients who reside in the regions.

Methods: To develop the models and set standards for the necessary personnel and facilities for the initial management plan, we held workshops, debates, and conference meetings with various experts.

Results: After partitioning the plan into two parts (the operational autonomy and the functional comprehensiveness), three models were developed: the 'independent regional cardiac surgery center' model, the 'satellite cardiac surgery center within hospitals' model, and the 'extended cardiac surgery department within hospitals' model.

Factors associated with ADL and IADL dependency among Korean centenarians: reaching the 100-year-old life transition.

This study aims to examine the functional status of Korean centenarians, who have crossed the relatively rare but increasingly common life transition of living for a century. As functional health is one of the essential components of healthy aging, our primary objective is to identify the correlates of two aspects of functioning, activities of daily living (ADL) and instrumental activities of daily living (IADL). Using a census survey conducted by the Korean National Statistical Office (KNSO) in 2005, we documented ADL and IADL limitations and analyzed their relationship to sociodemographic factors, health behaviors, social connectedness, and presence of diseases.

Relationship between intention of novel influenza A (H1N1) vaccination and vaccination coverage rate.

We carried out this study to describe the difference between intention to receive vaccine against influenza A (H1N1) before the vaccination campaign and actual vaccine coverage rate after vaccination campaign; and to find out the factors affecting the acceptability. We analyzed data on intention to receive vaccine against influenza A (H1N1) and actual vaccination coverage rate from IR (immunization registry). In a survey of pre-vaccination, the sample size was 1042 and the survey results were weighted with gender and age distribution for sample distribution to be similar to population distribution.

First-year treatment adherence among outpatients initiating antihypertensive medication in Korea: results of a retrospective claims review.

Background: Patients' adherence to antihypertensive drug therapy-especially at the beginning of treatment-is essential for preventing serious cardiovascular complications over the long term.

Objectives: This study was conducted to assess adherence among hypertensive patients who initiated antihypertensive pharmacotherapy and to identify whether it was related to the medical provider, dispensing patterns, or comorbidities.

Methods: We reviewed the computerized claim records submitted to Korea's Health Insurance Review Agency (which maintains data for all medication prescriptions for Korean residents) between July 2004 and December 2006.

[The knowledge, attitude and practice of blood pressure management from the patient's viewpoint: a qualitative study].

Objectives: This study adopted a qualitative method to explore the layman's beliefs and experience concerning high blood pressure and its management in order to develop a strategy to increase adherence to proper medical treatment.

Methods: Semi-structured interviews that focused on personal experiences with hypertension and its management were conducted with 26 hypertensive patients. The participants were selected according to a BP above 140/90 mmHg (hypertension stage 1), based on the seventh report of the Joint National Committee on prevention, detection, evaluation and treatment of high blood pressure (JNC-VII).

[The relations of socioeconomic status to health status, health behaviors in the elderly].

Objectives: To analyze the relationships of socioeconomic status(SES) to health status and health behaviors in the elderly.

Methods: Data were obtained from self-administered questionnaire of 4,587 persons, older than 65 years, living in a community. We measured the sociodemographic characteristics, socioeconomic status, health status (subjective health status, acute disease, admission experience, dental state, chronic disease etc.

Epidemiological study of clonorchiasis and metagonimiasis along the Geum-gang (River) in Okcheon-gun (county), Korea.

The endemic status of clonorchiasis and metagonimiasis along the Geum-gang (River) in Okcheon-gun (County) in Korea was examined. From February to December 2000, stools of total 1,081 inhabitants living in 5 villages were examined. Each stool specimen was examined by both the cellophane thick smear method and the formalin-ether sedimentation technique.
