Survival Analysis of Sputum Conversion Time among Patients with Drug Resistant Tuberculosis in Kenya

Drug-resistant tuberculosis (DR-TB) is a form of antimicrobial resistance <em>Mycobacterium tuberculosis</em> that is difficult and costly to treat. It is caused by TB bacteria resistance to at least one of the first-line existing TB medications, resulting in fewer treatment options and increasing mortality rates. In 2019, close to 500,000 people developed DR-TB, and 182,000 died globally. Less than 60% of DR-TB patients who started on medication were completed, mostly due to high mortality and lost follow-up.
