Evaluation of tuberculosis surveillance at the border area of Buriram Province, Thailand, 2018

Abstract

Background: Buriram province composed of 3 districts in the south that borders Cambodia which are Lahansai district, Ban Kruat district and Non Din Daeng district. Buriram has 3 border area point of entry at Chong Sai Ta Ku, Chong Chan Thop Pet and Chong Ba Ra Nae. In 2018, 3 districts area of Buriram had 178,282 population. Lahansai district, Ban Kruat district and Non Din Daeng district had 53, 69 and 16 people infected with Mycobacterium tuberculosis. So the calculated proportion of case detection and registration were 42%, 47% and 29%, respectively. As these 3 districts are border area, there might be an outbreak of tuberculosis disease.
Methods: A cross-sectional study was conducted to evaluate tuberculosis surveillance at Lahansai Hospital, Ban Kruat Hospital and Non Din Daeng Hospital from 1 October 2017 to 30 September 2018. The quantitative data was collected by the outpatient and inpatient medical record audit form, 506 report and TBCM online data. Both quantitative and qualitative data were analyzed by descriptive statistics; percentage, median, mean, minimum, and maximum and content analysis respectively.
Results: Totally charts of 2025 patients were reviewed, 475 from Lahansai Hospital, 1091 from Kruat Hospital, and 459 from Non Din Daeng Hospital. They were 138 patients from TB codes, and 1,878 patients from non-TB codes which we found 9 TB cases. Overall, we found 147 TB patients. For the 506 reporting system, the sensitivity was 91% (Lahansai Hospital) and positive predictive value (PPV) was 62%. For the TBCM online, the sensitivity and PPV were 94% and 100%, respectively. The qualitative part found that the system was flexible and simple. Definite and clear policy, structure and responsible officer were needed for system stability.
Discussion and Conclusion: The tuberculosis prevention and control surveillance system of 3 districts in Buriram border has sensitivity and PPV at acceptable levels. Not all districts reported to the 506 system. The acceptance in terms of perceived ease of use was at a good level and the system was not a burden to hospital service quality.
