Optimizing Diagnostic Resources for Tuberculosis: Utilization Patterns of Diagnostic Tests at the District Chest Clinic and Microscopy Centers in Galle District, Sri Lanka

Tuberculosis (TB) is prevalent in Sri Lanka and poses a considerable public health issue, even though the country is categorized as having a low burden of the disease.It ranks as the second most significant infectious disease in Sri Lanka, with around 500 to 600 fatalities each year.Early detection and effective treatment of all TB cases are crucial strategies for preventing deaths and alleviating the disease's impact.Consequently, individuals exhibiting symptoms of TB, as well as those who have been in close contact with confirmed cases, should undergo thorough investigations.Thus, evaluating the use of diagnostic resources at the district chest clinic and microscopy centers in Galle is essential for accurately diagnosing TB in the area and breaking the transmission chain.This research examines how diagnostic tests for TB are utilized at the District Chest Clinic and microscopy centers in the Galle district of Sri Lanka.The study aims to evaluate the effectiveness of test usage, identify testing trends, and suggest recommendations for better resource management and enhanced patient outcomes.A significant issue identified was the underutilization of sputum microscopy centers at the District Chest Clinic and microscopy facilities in Galle.To address this problem, a fish-bone diagram was employed to pinpoint contributing factors, followed by proposed interventions.The PACE Matrix was utilized to prioritize these interventions.Key solutions identified include regular staff training and capacity building, periodic supervision and review meetings, raising community awareness and education, and streamlining referral processes to improve overall conditions.
