The screening protocol and reporting system of pulmonary tuberculosis were simple, rapid, and effective. The surveillance system was flexible, stable, and useful. Sensitivity was 95.57% and positive predictive value was 98.23%. The timeliness of reporting the surveillance system was 94.59%. The completeness of the data was 100.00% while the accuracy was 97.27%. The data in surveillance system in Phrae province could represent the collected data in medical records effectively.
