Abstract
The purpose of this study is to evaluate TB surveillance system evaluation in community hospitals, eastern Tak province, fiscal year 2021-2022. A cross-sectional study was conducted in these 3 hospitals by reviewing medical records of patients TB during fiscal year 2021-2022. Standard TB case definitions were used. The study compared data from the TB surveillance system (National Tuberculosis Information Program: NTIP) with those from medical records of TB to determine quantitative attributes of surveillance evaluation. Qualitative attributes were determined by interviewing health personnel involving the NTIP. Of the medical records reviewed, 94 cases met TB case definitions and 90 were reported in NTIP. Ninety cases were found in both TB medical record reviews and NTIP. The overall sensitivity of TB surveillance was 95.7%. The predictive value positive was 100.0% in all 3 hospitals. Data of NTIP could be representative. Distributions of gender, age, nationality, sub-district address and month of TB treatment initiation in NTIP were corresponding to those in medical record reviews. Data quality of NTIP was very good, with 100.0% complete reporting of study variables in all 3 hospitals. About 94.4% of TB cases could be reported within one week in NTIP. All health personnel stated that the surveillance system was acceptable, simple, flexible, stable and useful.
