Evaluation of the National Tuberculosis Database System, “Tuberculosis Case Management (TBCM)”, for its Surveillance Function at Mae Sot Hospital, Thailand

Abstract

Thailand is classified by the World Health Organization as one of a few countries in the world with the highest tuberculosis (TB) burden. The Thai Ministry of Public Health has implemented the ‘Tuberculosis Case Management’ (TBCM) as the main database for the national TB surveillance. TBCM is designed for case registration and management as well as case reporting and notification. This study thus aimed to evaluate TBCM for its surveillance function. A cross-sectional descriptive study was conducted to review the surveillance function of TBCM during 1 Jan to 30 Jun 2017 at Mae Sot Hospital, Thailand. The study team reviewed the protocols and guidelines of TBCM. The practice of health personnel at the TB clinic was observed to determine the data flow of TBCM. Qualitative and quantitative study methods were employed in accordance with the Center for Disease Control and Prevention’s Guidelines for Evaluating Surveillance Systems. We found that TBCM reporting system at Mae Sot Hospital was acceptable, stable and useful in achieving the objectives of TB control program. Sensitivity and positive predictive value of TBCM accounted for 80.8% and 99.4% respectively. The most common reason of miss-reporting was a loss to follow-up after admission or after health exam, particularly amongst non-Thai patients. Timeliness and data quality were concerned attributes that required improvement. TBCM and the in-house medical recording system should be harmonized to mitigate the risk of erroneous coding.
