Abstract
PURPOSE
To estimate the prevalence of co-prescribing contraindicated drugs for elderly patients in Busan.
METHODS
We used the Health Insurance Review Agency (HIRA) claims database. Study population consisted of elderly patients who visited clinics or hospitals in Busan metropolitan city from January 1, 2000 to December 31, 2001. Contraindicated drugs were defined as 162 combinations of contraindicated drugs announced by the Korea Ministry of Health and Welfare in 2004. The co-prescription of contraindicated drugs was defined as prescribing two or more contraindicated drugs in combination in the same prescription. The prevalence of co-prescribing contraindicated drugswas estimated as proportion of co-prescribed patients out of the study patients. We estimated and age-adjusted prevalence and its 95% confidence interval of co-prescription of contraindicated drugs among the elderly patients in Korean population in 2001.
RESULTS
The study elderly patients were 262,952 with 2,483,227 prescriptions. Among the study patients 1,208 (4.6%) were prescribed contraindicated drugs in combination. A total of 16,255 patients were estimated as the number of co-prescribed patients among the Korean elderly in 2001. Age-standardized prevalence of co-prescription to the Korean elderly was estimated to be 45 per 10,000 persons. The most frequently prescribed combinations were cisapride & amitriptyline, roxithromycin & ergoloid mesylate, and terfenadine & erythromycin, and the frequency were 325 (16.8%), 149 (7.7%), and 132 (6.8%),respectively.
CONCLUSIONS
The contraindicated drugs were co-prescribed to the elderly patients in Korea. Many of these co-prescriptions should be avoided if unnecessary. The patients should be carefully monitored if they were inevitably prescribed the contraindicated drugs.

Abstract
PURPOSE
This study was conducted to estimate incidence, mortality and survival rate of lung cancer in the elderly people in Korea.
METHODS
Study population was Korean Elderly Phamacoepidemiologic Cohort (KEPEC). The lung cancer incidence cases were detected from three different sources, medical utilization database of the Korea Medical Insurance Corporation (KMIC), the database from the National Cancer Registry, and the database from the Regional Cancer Registry. The hospital survey to confirm the final diagnosis of the potential cases was conducted. A specialist on lung cancer reviewed the abstracted data to confirm the final diagnoses. The lung cancer death cases were detected from the mortality database at National Statistical Office. Incidence rate, survival rate and mortality rate of lung cancer and their 95% confidence intervals were estimated with SAS Window ver. 8.1. PESULTS: There were 213 confirmed lung cancer cases in KEPEC between Jan. 1994 and Dec. 1998. Age-standardized incidence rate of lung cancer to the Korean population was estimated to be 316.9 per 100,000 person-years in male and 65.2 per 100,000 person-years in female. Age-standardized mortality rate of lung cancer to the Korean population was estimated to be 342.3 per 100,000 person-years in male and 84.8 per 100,000 person-years in female. One year survival rate was 17% in male and 11% in female. Two year survival rate was 2% in male and 4% in female.
CONCLUSION
Age-standardized incidence rate, age-standardized mortality rate and survival rate of lung cancer in the elderly Korean may be useful for further study and making health policy for managing lung cancer in the elderly.
