Quality Improvement in Tuberculosis Care Systems

Quality improvement in tuberculosis (TB) care systems encompasses systematic efforts to enhance the reliability, safety, and effectiveness of services that prevent, diagnose and treat TB. Central to these endeavours is the mapping of patient journeys through the care cascade—from initial symptom recognition to successful, recurrence-free outcomes—and identification of bottlenecks at each stage. Strategies include strengthening diagnostic networks, standardising clinical pathways, engaging private and public providers, and embedding continuous performance measurement. Emphasis on data intelligence and collaborative governance promotes patient-centred partnerships and supports adaptive interventions at local, regional and national levels. In many high-burden settings, integrating quality standards into mixed health-system environments has yielded notable increases in case notifications and microbiological confirmations, while reducing diagnostic delays and loss to follow-up. Innovative methodologies such as standardised patient studies and real-time surveillance platforms facilitate actionable insights into provider practices, enabling targeted training, guideline reinforcement and antimicrobial stewardship. As the global TB community aspires to elimination, quality improvement frames both incremental gains in service delivery and transformative system-level change, with equity and universal access as guiding principles.
