Introduction: Tuberculosis (TB) data are used to evaluate the effectiveness of TB program interventions, identify deficiencies, and inform policies and programs. These data are also used for advocacy, resource mobilization, and allocation, both nationally and internationally. This study is aimed at verifying the reliability of the data collated and submitted from the direct observation therapy strategy (DOTS) facilities to the National TB Program (NTP) in some selected states in Southern Nigeria. Materials and Methods: A total of 29 facilities providing TB services were purposively selected from six states in Southern Nigeria, based on the treatment success rate as reported in 2009. In each selected facility, the following records were reviewed for concordance: Patient treatment cards and facility TB register, facility TB register and facility laboratory register, facility TB register and local government area (LGA) TB register, and LGA TB register and TB quarterly reports. Furthermore, a total of 273 patients were selected for interview to validate the information contained in the treatment cards. Results: Agreement between the data sources was relatively high, though higher in some states than the others. Agreement between patient treatment card and facility TB register, and facility TB register and laboratory register were 97% and 85%, respectively. The lowest concordance was observed between the facility TB register and the LGA TB register. All the patients interviewed confirmed the information as recorded in their treatment cards. Conclusion: The study revealed that NTP data in Southern Nigeria is fairly reliable; however, there are variations observed among the states and at various levels. This study underlines the need to improve TB surveillance data in some states, particularly at the facility and at the LGA levels.
