Medical Services Utilization among Lipid-Modifying Drug Users

BACKGROUND: Several practice guidelines for management of dyslipidemia including the National Cholesterol Education Program recommend regular physician follow-up and lipid testing to promote adherence with lipid-modifying drugs. The objective of this study was to analyze the pattern of medical care use among lipid-modifying drug users. METHODS: A retrospective cohort study was conducted with 57,801 new users of lipid-modifying drugs who initiated treatment in 2005. The Korean National Health Insurance Claims Data was used to examine the pattern of medical care use and related factors after treatment initiation for up to two years. Getting the prescription and follow-up lipid testing were considered use of medical care. RESULTS: More than 95% of the patients visited physicians for prescriptions or lipid testings in the first year after initiating drug therapy. In the first two months, 77% had both prescription and follow-up lipid testing, while in the second year, approximately 57% had. Rate for follow-up lipid testing in the first two months was about 78%, but 55% in the second year. Approximately 74% of the patients continued using ambulatory medical care in the second year. In multiple logistic regression analysis, the probability of continual visits in the second year increased in patients who visited one medical institution for prescription and lipid testing within six months. CONCLUSIONS: Early and frequent visits, especially for lipid testings, were associated with continuous medical care use. Patients should be educated regarding the importance of dyslipidemia management in the early stage after treatment initiation.

Complementary and Alternative Medicine (CAM) Use and Its Determining Factors among Patients with Rheumatic Disorder in Korea

BACKGROUND: There is a wide spread increase in the use of CAM by patients with rheumatic disease. This study was performed to identify the prevalence of CAM use and determining factors affecting CAM use by patients with rheumatic disease. METHODS: From October 23 to November 31 in 2003, face-to-face structured interviews were conducted in a rheumatology hospital in Seoul. A total of 182 patients with rheumatic disease, who visited the hospital, participated. RESULTS: CAM was used by 59.3% (95% CI=52.1~66.2%) of the patients with rheumatic disease. The most common use of CAM was traditional Chinese medicine such as acupuncture and herbs. Demographic variables were not predictive for the use of CAM. As the duration of disease was longer, probability on CAM use was lower (odd ratio: 0.922, 95% CI=0.855~0.994). CAM use on disabled people who registered were 4.623 (95% CI=1.105~19.348) times higher than non-disabled. CONCLUSION: CAM use is common in patients with rheumatic disease. The duration of disease and physical disability were the influencing factors for using CAM. These findings support a need for outcome studies on the effectiveness of CAM in rheumatic disease, as well as the improvement of providing patients with information on CAM usage.
