About a quarter of the world’s population is infected with Mycobacterium tuberculosis, bacteria that causes TB, of which 5–10% will develop TB disease during their lifetime (WHO Global Tuberculosis Report (2021). The WHO End TB Strategy (2015) envisions a 95% reduction in deaths due to TB by 2035. TB bacteriological diagnosis involves examining suspects’ sputum samples to identify the bacteria that cause TB. GeneXpert machines are among the methods used to test the presence of these bacteria. It allows laboratory scientists to retrieve sample results via a software interface or downloadable files through a communication linkage with external systems. Without such communication linkage, lab scientists feed the results manually to the patient management system, which is time-consuming and prone to errors. Due to this challenge, UDSM DHIS2 lab, in collaboration with the NTLP and National Institute of Medical Research (NIMR), implemented the interfacing adapter to link ten (10) color module GeneXpert machines with the DHIS2 ETL, a tracker-based system that monitors TB patients throughout the treatment course, to ensure timely flow of quality diagnosis results.
