Tuberculosis Screening and Control in Phrae Prison
Keywords:
Tuberculosis, Prison, TB screeningAbstract
The stop TB strategy was launched in Thailand in 2006. We emphasized the detection of TB cases in high risk group, this included screening tuberculosis in prison. This study was aimed to measure prevalence and incidence of TB in prison and to compare TB incidence between TB in prison and in the community. Risk group of tuberculosis among prisoners was identified by questionnaires. Those with at least one risk questionnaire, sputum would be collected with chest radiograph. Pulmonary TB were treated if they had smear positive or chest X-ray was compatible with pulmonary TB. New prisoner would be screened for TB before entry. The result revealed that out of 705 prisoners, 182(25.8%) were identified as high risk group and provided with CXR, 16 films were compatible with PTB (6 old PTB, 1 NTB, 1 COPD, 8 new PTB). There were 107 cases with sputum collected of which 2 of them had smear positive. The prevalence was 19.86/1000, incidence was 11.35/1000. Prisoners had up to 7.99 times at risk to have TB more than civilians (95% CI 3.62-16.88). In conclusion, tuberculosis prevalence and incidence in prison remained higher than that in the community. We could detect TB cases with chest radiograph more than sputum examination. The screening strategy by CXR was useful to detect TB in prison, but further investigation with bacteriological confirmed should be done. The strategy presented an opportunity to treat and provide prevention of TB in prison.
