2.7 Enabling and promoting research
A total of 49 countries including 19 HBCs reported that operational research activities were implemented in 2006. The countries with the largest programmes of operational research (in terms of the number of studies being done) were China and India. The most common topics were related to the following components of the Stop TB Strategy: DOTS (around 40 studies, with examples including how to improve diagnosis and patient care); TB/HIV, MDR-TB and other challenges (about 40 studies); and PPM (7 studies). Many countries also reported conducting surveys of drug resistance and prevalence of disease, as well as plans to conduct in-depth analysis of the impact of TB control using routine surveillance data (see also sections 2.2.6 and 2.3.2 above).
