Background

In-training examination (ITE) is a cognitive examination similar to the written test, but it is different from the Clinical Practice Examination of the Korean Academy of Family Medicine (KAFM) Certification Examination (CE). The objective of this is to estimate the positive predictive value of the KAFM-ITE for identifying residents at risk for poor performance on the three types of KAFM-CE.

Methods

372 residents who completed the KAFM-CE in 2011 were included. We compared the mean KAFM-CE scores with ITE experience. We evaluated the correlation and the positive predictive value (PPV) of ITE for the multiple choice question (MCQ) scores of 1st written test & 2nd slide examination, the total clinical practice examination scores, and the total sum of 2nd test.

Results

275 out of 372 residents completed ITE. Those who completed ITE had significantly higher MCQ scores of 1st written test than those who did not. The correlation of ITE scores with 1st written MCQ (0.627) was found to be the highest among the other kinds of CE. The PPV of the ITE score for 1st written MCQ scores was 0.672. The PPV of the ITE score ranged from 0.376 to 0.502.

Conclusion

The score of the KAFM ITE has acceptable positive predictive value that could be used as a part of comprehensive evaluation system for residents in cognitive field.

Background
: Serum alpha-fetoprotein(aFP) is a useful diagnostic test on hepatocellular carcinoma(HCC) However, it is still questionable appropriate screening test or not

Methods : A total of 24,050 patients who visited the General Health Screening Center of Asan Medical Center from June, 1993 to June, 1994, were reviewed by chart and telephone survey. Among them 70 cases where serum aFP were elevated > 20ng/ml and 16 cases where HCC was suspected by abdominal ultrasonogram were selected and investigated for the existence of HCC. Four groups were divided into HBsAg(+), Anti-HCV(+), increased AST/ALT(abnormal LFT) and normal group. Each group was evaluated for sensitivity, specificity, positive, predictive value and negative predictive value of serum aFP for HCC.

Results : The prevalence of elevated aFP was 0.29%(70/24,050). There was a statistically significant difference between sexes. And the total number of HCC as 10 cases (42/100,000). With aging, the prevalence of HCC was increased. The prevalence rate pf elevated serum aFP and HCC had significant difference in anti-HCV(+), HBsAg(+) and abnormal LFT group compared to normal group(sGOT < 40U/1, HBsAg(-) and Anti-HCV(-)) (P<0.01).
In our study, sensitivity and positive predictive value of serum aFP for HCC were 100% and 14% in anti-HCV(+) group, 83.3% and 8.6% in abnormal LFT group, 80% in HBsAg(+) group, and 0% in normal group, respectively.

Conclusion : Serum aFP as a screening test for HCC in asymptomatic healthy people does not seem to be not valid. But it seems to be appropriate when it is applied for cases of abnormal LFT(sGOT >40U/1 or sGPT > 40U/1), HBsAg(+) and Anti-HCV(+) people.
