Interregional workshop for analysis of data from anti-tuberculosis drug resistance surveys
10–12 December 2013, Copenhagen, Denmark
In settings that do not have the capacity to conduct surveillance of drug-resistant tuberculosis (TB) based on routine drug sensitivity testing of M. tuberculosis isolates of all TB cases, surveys should be conducted periodically, as per WHO’s “Guidelines for surveillance of drug resistance in tuberculosis” (4th edition, 2009). In order to arrive at a reliable estimate of the prevalence of multidrug-resistant (MDR) TB amongst new and/or previously treated TB cases, the design and analysis of these surveys requires consideration of issues such as the clustering of data and missing values.
4 countries have recently completed, or will soon complete, an anti-TB drug resistance survey; namely, Azerbaijan, Pakistan, South Africa and Turkmenistan. In order to share the experiences of these 4 countries and ensure that the data generated are correctly analysed and interpreted, an interregional data analysis workshop will be held on 10–12 December 2013 in Copenhagen, Denmark.
The specific objectives of the workshop are:
- to share the experiences of countries in conducting anti-TB drug resistance surveys, including challenges and recommendations for drug resistance surveillance in the future;
- to provide training on statistics for the analysis of survey data, including accounting for missing values and clustered data;
- to assist countries in generating reliable estimates of the prevalence of MDR-TB amongst new and/or previously treated TB cases, to characterize drug resistance patterns, and to assess risk factors for MDR-TB.
