The Berlin Declaration on tuberculosis • Berlin, 22 October 2007 • 49 country delegations • Commitment to: - strengthen TB control - adopt the Stop TB Strategy - ensure sustainable financing
The Stop TB Strategy • Pursue high-quality DOTS expansion and enhancement(political commitment, quality bacteriology, guaranteed treatment, ensured drug supply, monitoring and evaluation) • Address TB-HIV, MDR-TB and other challenges(prisoners, other risk groups) • Contribute to health system strengthening • Engage all care providers(public-private, international standards) • Empower patients and communities(ACSM, community participation, patients’ charter) • Enable and promote research
Plan to Stop TB in 18 high-priority countries of the WHO European Region, 2007-2015 US$ billion Needed 14.8 Available 6.7 Gap 8 (i.e. 1- 3.1 US$ per person by governments)
Global Fund funds increasing for TB control; EUR, 2002-06 US$ million
Health systems: merging interests with Stop TB Health system Stop TB DOTS (political commitment, quality bacteriology, guaranteed treatment, ensured drug supply, monitoring and evaluation) Leadership and governance Financing TB/HIV, MDR-TB, etc. Health work force Health system strengthening Medical products and commodities Engage all providers Empower patients and communities Information Service delivery Research
Health systems: opportunities for TB delivery at PHC level • Suspect TB and react quickly • Collect 3 sputum samples from each suspect • Smear samples and/or send samples to designed laboratory for microscopy • Refer TB suspects for early TB diagnosis • Provide directly observed treatment (DOT) • Coordinate support to TB patients • Trace treatment defaulters • Refer patients with adverse drug reactions • Keep TB records and reporting • Monitor populations at special risk of TB • Educate patients, families, community • Check TB contacts (symptoms, skin testing) • Provide BCG vaccination
Health systems: reform leading to improved TB control TARGET Kyrgyzstan: Manas Taalimi Reform, phase II (2001-2006) Note: progress in new sputum smear-positive cases under DOTS
