Screening patients with Diabetes Mellitus for Tuberculosis in China.

Objective  There is a high burden of both diabetes (DM) and tuberculosis (TB) in China, and as DM increases the risk of TB and adversely affects TB treatment outcomes, there is a need for bidirectional screening of the two diseases. How this is best performed is not well determined. In this pilot project in China, we aimed to assess the feasibility and results of screening DM patients for TB within the routine healthcare setting of five DM clinics. Method  Agreement on how to screen, monitor and record was reached in May 2011 at a national stakeholders meeting, and training was carried out for staff in the five clinics in July 2011. Implementation started in September 2011, and we report on 7 months of activities up to 31 March 2012. DM patients were screened for TB at each clinic attendance using a symptom-based enquiry, and those positive to any symptom were referred for TB investigations. Results  In the three quarters, 72% of 3174 patients, 79% of 7196 patients and 68% of 4972 patients were recorded as having been screened for TB, resulting in 7 patients found who were already known to have TB, 92 with a positive TB symptom screen and 48 of these newly diagnosed with TB as a result of referral and investigation. All patients except one were started on anti-TB treatment. TB case notification rates in screened DM patients were several times higher than those of the general population, were highest for the five sites combined in the final quarter (774/100 000) and were highest in one of the five clinics in the final quarter (804/100 000) where there was intensive in-house training, special assignment of staff for screening and colocation of services. Conclusion  This pilot project shows that it is feasible to carry out screening of DM patients for TB resulting in high detection rates of TB. This has major public health and patient-related implications

Screening of patients with diabetes mellitus for tuberculosis in community health settings in China.

OBJECTIVE: To assess the feasibility and results of screening of patients with DM for TB in routine community health services in China. METHOD: Agreement on how to screen patients with DM for TB and monitor and record the results was obtained at a stakeholders meeting. Subsequent training was carried out for staff at 10 community health centres, with activities implemented from June 2013 to April 2014. Patients with DM were screened for TB at each clinical visit using a symptom-based enquiry, and those positive to any symptom were referred to the TB clinic for TB investigation. RESULTS: A total of 2942 patients with DM visited these ten clinics. All patients received at least one screening for TB. Two patients were identified as already known to have TB. In total, 278 (9.5% of those screened) who had positive TB symptoms were referred for TB investigations and 209 arrived at the TB centre or underwent a chest radiograph for TB investigation. One patient (0.5% of those investigated) was newly diagnosed with active TB and was started on anti-TB treatment. The TB case notification rate of those screened was 102/100,000. CONCLUSION: This pilot project shows it is feasible to carry out TB screening among patients with DM in community settings, but further work is needed to better characterise patients with DM at higher risk of TB. This may require a more targeted approach focused on high-risk groups such as those with untreated DM or poorly controlled hyperglycaemia
