Magnitude and Reasons for Gaps in Tuberculosis Diagnostic Testing and Treatment Initiation: An Operational Research Study from Dakshina Kannada, South India.

Background: In India, ensuring all Persons with Presumptive TB (PPTB) undergo TB diagnostic tests and initiating all diagnosed TB patients on treatment are two major implementation challenges.

Objectives: In a coastal district of Karnataka state, South India, to (1) determine the number and proportion of PPTB who did not undergo any TB diagnostic test, and the number and proportion of TB patients who were not initiated on treatment (2) explore the facilitators and barriers in TB diagnostic testing and treatment initiation from health care providers' perspective.

Methods: For objective-1, we used a cross-sectional design involving review of data of PPTB enrolled for care during January-March 2019 and for objective-2, we used a qualitative design involving key informant interviews of health care providers.

Are they there yet? Linkage of patients with tuberculosis to services for tobacco cessation and alcohol abuse - a mixed methods study from Karnataka, India.

Background: Tobacco use and alcohol abuse are associated with higher risk of tuberculosis (TB) infection, progression to active TB and adverse treatment outcomes among patients with TB. Revised National Tuberculosis Control Programme (RNTCP) treatment guidelines (2016) require the documentation of tobacco and alcohol use among patients with TB and their linkage to tobacco and alcohol abuse treatment services. This study aimed to assess the extent of documentation of tobacco and alcohol usage data in the TB treatment card and to explore in-depth, the operational issues involved in linkage.
