Can we optimise the TB response amid funding constraints using evidence-based, cost-effective strategies.

BACKGROUND: Despite progress in the TB response, including through the Global Fund's catalytic efforts, funding gaps and inefficiencies threaten efforts to sustain gains and accelerate the TB response. Recent donor funding cuts have further strained programmes in low- and middle-income countries.

METHODS: A mixed-method, combining desk and literature review and key informant interviews with national TB programme stakeholders, technical experts, and partners, was conducted using standardised tools. Findings were triangulated to identify strategies/approaches that improve efficiency, access, and outcomes.

RESULTS: We identified cost-effective strategies that optimise resources and tools to sustain and expand access to services amid declining funding. Strategies to enhance efficiency include screening using digital X-rays (with artificial intelligence), testing samples (including pooled samples) with molecular diagnostics, decentralising care, engaging communities and private sector, and integrating TB services with broader health system. Cost-saving measures involve integrated sample transport and supervision, integrating TB with other diseases such as HIV, diabetes, and undernutrition, task shifting, shorter treatment regimens, digital tools, and e-learning. Emphasis was also placed on innovative financing, domestic resource mobilisation, and country ownership.

CONCLUSION: Accelerating to end TB requires integrated and efficient strategies, innovative financing, and increased domestic resources, ensuring provision of equitable and high-quality TB services while strengthening the health system and ensuring sustainability.
