Objectives
In Korea, a large portion of tuberculosis (TB) patients are diagnosed and treated in private institutes. Laboratory tests are crucial for TB control. There are many possible problems using laboratory tests in the private sector. In this study, we aimed to investigate the characteristics and trends of utilizing laboratory tests for TB and mycobacterial diseases in the private sector by analyzing the National Health Insurance (NHI) database.
Methods
After selecting TB or other mycobacteria-related test items, we searched the number and cost of each item on the website of the Health Insurance Review and Assessment Service using the code of each test from 2007 to 2012.
Results
Our data revealed that the number and cost of tests drastically increased between 2007 and 2012. Culture and molecular tests primarily contributed to the tremendous increases. For each year, concentrated smearing and fluorochrome staining were more commonly used. The number of serologic tests for latent TB infection stagnated, despite the expansion of contact investigation.
Conclusion
The NHI data could be considerably useful for understanding the utilization trends of laboratory tests for TB and mycobacterial diseases in Korea. Our data showed that TB laboratory systems have recently improved. In this study, many issues were noticed. Therefore, solutions to these issues are required and the continued monitoring of NHI data regarding laboratory diagnosis.

Abstract PDF

Objectives
A fast and accurate diagnosis is necessary to control and eliminate tuberculosis (TB). In Korea, TB continues to be a serious public health problem. In this study, diagnostic tests on clinical samples from patients suspected to have TB were performed and the sensitivity and specificity of the various techniques were compared. The main objective of the study was to compare various diagnostic tests and evaluate their sensitivity and specificity for detecting tuberculosis.
Methods
From January 2013 to December 2013, 170,240 clinical samples from patients suspected to have TB were tested with smear microscopy, acid-fast bacilli culture, and real-time polymerase chain reaction (PCR). The test results were compared and data were analyzed.
Results
A total of 8216 cultures tested positive for TB (positive detection rate, 4.8%). The contamination rate in the culture was 0.6% and the isolation rate of nontuberculous mycobacteria was 1.0%. The sensitivity and specificity of smear microscopy were 56.8% and 99.6%, respectively. The concordance rate between the solid and liquid cultures was 92.8%. Mycobacterium isolates were not detected in 0.4% of the cases in the liquid culture, whereas no Mycobacterium isolates were detected in 6.8% of the cases in the solid culture. The sensitivity and specificity of real-time PCR for the solid culture were 97.2% and 72.4%, respectively, whereas the corresponding data for the liquid culture were 93.5% and 97.2%.
Conclusion
The study results can be used to improve existing TB diagnosis procedure as well as for comparing the effectiveness of the assay tests used for detecting Mycobacterium tuberculosis isolates.
