INTRODUCTION: Diabetes mellitus (DM) and tuberculosis (TB) are of great public health importance globally, especially in Sub-Saharan Africa. Tuberculosis is the third cause of death among subjects with non-communicable diseases. DM increases risk of progressing from latent to active tuberculosis. The study aimed to ascertain yield of TB cases and the number needed to screen (NNS) among DM patients. MATERIAL AND METHODS: Across-sectional study was conducted at 10 health facilities with high DM patient load and readily accessible DOTS center in 6 states of southern region of Nigeria over aperiod of 6 months under routine programme conditions. All patients who gave consent were included in the study. Yield and NNS were calculated using an appropriate formula. RESULTS: 3 457 patients were screened with amean age (SD) of 59.9 (12.9) years. The majority were male, 2 277 (65.9%). Overall prevalence of TB was 0.8% (800 per 100 000). Sixteen (0.5%) were known TB cases (old cases). There were 221 presumptive cases (6.4%) out of which 184 (83.3%) were sent for Xpert MTB/Rif assay. Eleven (0.3%) new cases of TB were detected, giving additional yield of 40.7% and the number needed to screen (NNS) of 315. All the 11 patients were placed on anti-TB treatment. CONCLUSIONS: The prevalence of TB among DM patients was higher than in the general population. The yield was also good and comparable to other findings. This underscores the need for institute active screening for TB among DM patients. Further stu-dies are recommended to identify associated factors to guide policy makers in planning and development of TB-DM integrated services.
