40 Development of a standardized MDR/XDR-TB assessment and monitoring tool Giovanni Battista Migliori*, Giovanni Sotgiu^, Ernesto Jaramillo#, Fuad Mirzayev#, Rosella Centis*, Charlotte Colvin†, M. D’Arcy Richardson† * WHO Collaborating Centre for TB and Lung Diseases, Fondazione S. Maugeri, Care and Research Institute, Tradate, Italy; ^ Hygiene and Preventive Medicine Institute, University of Sassari, Sassari, Italy; # Stop TB Department, WHO, Geneva, Switzerland, †PATH, Seattle, Washington, USA The MDR/XDR TB Assessment and Monitoring Tool was developed to standardize evaluations of country capacity, to prevent, diagnose, and treat MDR/XDR-TB and identify program gaps. It provides data to guide national plans; generates baseline data to measure progress; provides information for GLC and GFATM applications; guides technical assistance; and informs donor investment. In field testing,the tool scoring system performed equally well in high- and low-prevalence settings. This GLC endorsed tool supports global efforts to contain MDR/XDR- TB and is useful to develop national MDR/XDR-TB control strategies. It is available at http://www.path.org/publications/details.php?i=1678.

57 Global Policy: MDR-TB and XDR-TB 1.Strengthen basic TB control, to prevent M/XDR-TB 2.Scale-up programmatic management and care of MDR-TB and XDR-TB 3.Strengthen laboratory services for adequate and timely diagnosis of MDR-TB and XDR-TB 4.Ensure availability of quality drugs and their rational use 5.Expand MDR-TB and XDR-TB surveillance 6.Introduce infection control, especially in high HIV prevalence settings 7.Mobilize urgently resources domestically and internationally 8.Promote research and development into new diagnostics, drugs and vaccines
58
58 THE BEIJING "CALL FOR ACTION" ON TUBERCULOSIS CONTROL AND PATIENT CARE : TOGETHER ADDRESSING THE GLOBAL M/XDR-TB EPIDEMIC We recognize the key barriers to effective management of M/XDR-TB lie throughout the health system and beyond… We therefore commit ourselves to accelerate efforts to prevent M/XDR- TB through effective TB care and control, and to scale-up the diagnosis and treatment of M/XDR-TB: - universal access to diagnosis and treatment of M/XDR-TB by 2015 - equitable access - comprehensive framework for management and care - HR, laboratories - coordination among public and private sectors - infection control - drug supply - improved surveillance, M&E - addressing social determinants - ACSM
