In Korea, clinical performance examination (CPX) has been included in license examination for medical doctors since 2009 in order to improve clinical performance of medical students. This study aimed to evaluate the contribution of CPX to medical education.
Clinical competency in the differential diagnosis of secondary headache was compared between the incoming interns in 2009 unexposed to CPX and the incoming interns in 2010 exposed to CPX, using the data of patients who visited the emergency department due to headache (181 patients seen by 60 CPX non-exposed interns and 150 patients seen by 50 CPX-exposed interns). We obtained the data by reviewing electronic medical records and nominal lists of doctors. Clinical competency was assessed by sensitivity and specificity between the diagnostic impression by interns and the final diagnosis. The association between CPX exposure and clinical competency in secondary headache diagnosis was evaluated using multiple logistic regression analysis.
When we assessed clinical competency on the basis of all listed diagnostic impressions, sensitivity and specificity were 67.9% and 80.0%, respectively, for headaches seen by CPX-exposed interns, and 51.7%, and 71.7%, respectively, for headaches seen by CPX non-exposed interns. Multivariable adjusted logistic regression analysis showed exposure to CPX was not associated with increased competency for identifying secondary headache.
Exposure to CPX as a part of the medical license examination was not effective for the improvement of clinical competency of interns in identifying secondary headache.

Death from uterine cervical cancer could be preventable by an active participation of women at risk in a screening program such as the Papanicolaou test. In order to examine the presence of socioeconomic disparity in preventable deaths, we evaluated the time trends of cervical cancer mortality by socioeconomic status in Korean women.
We selected level of educational attainment and marital status as surrogate indices of socioeconomic status. Using death certificate data and Korean Population and Housing Census data from Korea National Statistical office, we calculated age-standardized yearly mortality rates from cervical cancer between 1998 and 2009 according to the level of education as well as marital status.
Cervical cancer mortality peaked in 2003 and then decreased gradually over time. Cervical cancer mortality was the highest in the group with the lowest level of educational attainment in all age groups and the gap between the lowest and the highest educational level has increased over time. Cervical cancer mortality was lower in married women than unmarried women in all age groups, and the degree of difference did not change over time.
In the Korean population, socioeconomic differential in cervical cancer mortality has persisted over time.

Although cigarette smoking is a major modifiable risk factor for the occurrence of primary and secondary cardiovascular disease (CVD), not all survivors from CVD attacks can successfully stop smoking. However, little is known about the factors associated with the change in smoking behavior after CVD attack.
Study subjects included 16,807 participants (≥19 years) in the fourth Korean National Health and Nutrition Examination Surveys. From them, we selected 180 persons who had previous CVD diagnosis (angina pectoris, myocardial infarction, or stroke) and were smoking at the time of CVD diagnosis. Then, we categorized the 180 persons into two groups according to change in smoking status after the CVD: quitter and non-quitter. Logistic regression analysis was done to evaluate multivariable-adjusted association.
Even after CVD diagnosis, 63.60% continued to smoke. Fully-adjusted analysis revealed that regular drinking (odds ratio [OR], 4.44) and presence of smokers among family members (OR, 5.86) were significantly (P < 0.05) associated with greater risk of persistent smoking, whereas lower education level (OR, 0.20), larger amount of smoking (OR, 0.95), longer time since diagnosis (OR, 0.88), and diabetes (OR, 0.36) were significantly (P < 0.05) associated with decreased risk of persistent smoking after CVD.
A great proportion of CVD patients tended to continue smoking in the Korean population. In order to reduce smoking rates among CVD patients further, more aggressive efforts towards smoking cessation should be continuously made with consideration of individual socioeconomic, behavioral, and clinical characteristics of CVD patients.
