SUMMARY
Setting
Bangladesh – National Institute of Diseases of the Chest and Hospital, Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders and Chittagong Chest Disease Hospital.
Objective
To present operational data and discuss the challenges of implementing FAST (Find cases Actively, Separate safely and Treat effectively) as a TB transmission control strategy.
Design
FAST was implemented sequentially at three hospitals.
Results
Using Xpert MTB/RIF, 733/6028 (12.2%, 95%CI [11.4,13.0]) patients were diagnosed with unsuspected TB. Patients admitted with other lung diseases with a prior TB history had more than twice the odds of being diagnosed with unsuspected TB as those without a TB history (OR 2.6, 95%CI 2.2–3.0, p<0.001). Unsuspected MDR-TB was diagnosed in 89/1415 (6.3%, 95%CI [5.1,7.7]) patients. Patients with unsuspected TB had nearly five times the odds of being diagnosed with MDR-TB than those admitted with a known TB diagnosis (OR 4.9, 95%CI 3.1–7.6, p<0.001). Implementation challenges include staff shortages, diagnostic failure, supply-chain issues and reliance on external funding.
Conclusion
FAST implementation revealed a high frequency of unsuspected TB in hospitalized patients in Bangladesh. Patients with a prior TB history have increased risk. Ensuring financial resources, stakeholder engagement and laboratory capacity are important for sustainability and scalability.
