Background
The use of topical antibiotics (TA) for prophylactic purposes after clean dermatologic procedures (CDP) is generally not recommended, and the prescription of TA needs to be individualized in consideration of each patient’s situation and underlying disease. The aim of this study was to determine the proportion of patients who underwent CDP in outpatient settings and were prescribed TA inappropriately, as well as the factors that may affect the prescription of TA.
Methods
Outpatient visits coded for CDP were selected using claims data from the Health Insurance Review and Assessment Service in 2018. Of these, patients receiving TA prescriptions were classified as having inappropriate TA use, and the proportion was estimated through technical analysis. A logistic regression analysis was used to identify factors influencing inappropriate prescriptions.
Results
Data were analyzed using 423,651 visits, and TA was prescribed for approximately 1.9% of the visits. TA usage was higher among women (2.0%), 0–19 years of age (2.2%), medical aid (2.2%), clinic settings (2.4%), and metropolitan areas (2.0%). TA was prescribed more frequently in urology (8.6%), pediatrics (5.0%), and dermatology (4.2%) than in other specialties.
Conclusion
The prescription rate of TA after CDP was 1.9% using the 1.4 million patient sample from the national health insurance claims data in Korea, which is equally weighted to represent 50 million people. Although the proportion of inappropriate TA prescriptions in Korea is lower than that in other nations, it cannot be overlooked because of the large number of cases. Efforts to improve quality are required to reduce the number of inappropriate prescriptions.

Background
: According as people have an increased interest in early detection of disease and health promotion, people who take health examinations are increased. So this study is aimed to survey common problems about health in community and their frequency by way of investigation on diagnosis in health examination data and to evaluate the effects of risk factors on each disease patterns.

Methods : The medical records of the clients who have taken health examinations for the first time from March 1995 to February 2000 at a health examination center of a university hospital in Seoul were reviewed. The category and number of judged diagnosis, sociodemographic factors are compared and analyzed.

Results : The selected medical records accounted to 22,393. The study subjects consist of 11,544(51.6%) male. Mean age is 52.0±105 years(range 16~90). Mean number of judged diagnosis is 4.04±2.13(range 0~9) per one person and female took more diagnosis than male on an average(4.09±2.17 Vs 3.99±20.9). The organic diagnosis(56.4%) is most in total and other diagnosis is 35.7%, functional diagnosis is 7.9%. The common diagnoses are liver disease(7.17%), decreased physical strength(6.68), hyperlipidemia(6.53%), obesity(5.90%), osteoporosis or postmenopausal syndrome(4.72%), need for immunization against viral hepatitis(4.69%), hypertension(4.20%), functional gastrointestinal disease(3.93%). The number of total diagnosis and organic diagnosis is larger in older age, no exercise, female, smoker, no-spouse, lower education(p<0.05). The number of functional diagnosis is larger in female, younger age, non-smoker, lower education(p<0.05). The number of other diagnosis is larger in no exercise, smoker, female, younger age(p<0.05).

Conclusion : According to health examination, total diagnosis and organic diagnosis are influenced by age, exercise, sex, smoking, spouse, education, functional diagnosis is influenced by sex, age, smoking, education and other diagnosis is influenced by exercise, smoking, sex, age.
