DR-TB Coordinator

It is extremely important for any type of TB patient to be initiated on the right treatment at the earliest in order to have better treatment outcomes. Therefore as soon as the patient is diagnosed, s/he should immediately be traced with the help of the Community Health Officer (CHO) of the Health and Wellness Centres (HWC), TB Health Visitors (TBHV) / Senior Treatment Supervisor(STS) and the health facility doctors and initiated on the appropriate treatment regimen.

Steps in TB Treatment Initiation

Tuberculosis treatment and its different regimens have scientific backgrounds for their formulations. To understand this, we need to know about the mode of action of each anti-TB drug first.

Mode of Action of Anti-TB Drugs

Anti-TB drugs have the following three actions:

Under the National TB Elimination Programme (NTEP), strategies adopted in the treatment of TB are based on the available scientific and operational researches. These strategies are combined to ensure better treatment outcomes for the TB patients. The main strategies include:

Domiciliary Treatment

The goals of tuberculosis treatment are:

• Rendering the patient non-infectious, breaking the chain of transmission and decreasing the infection​ pool

• Decreasing case fatality and morbidity by ensuring relapse-free cure

• Minimising and preventing the development of drug resistance.  ​

To meet the goals of treatment, the regimens should be:

Check

It is crucial to make an effort for microbiological confirmation in presumptive Extrapulmonary Tuberculosis (EPTB) cases. Appropriate specimens from the Extrapulmonary (EP) site are collected and, depending on the specimen type and availability of facilities, the specimens are sent for:

• Cartridge-based Nucleic Acid Amplification Testing (CBNAAT)
• Culture and Drug Susceptibility Testing (C&DST) for M. tuberculosis 
• Histopathological examination

On the basis of diagnosis, Tuberculosis (TB) can be classified into 2 main types:

1. Microbiologically confirmed TB
2. Clinically diagnosed TB

Microbiologically Confirmed TB

Based on the site of disease, Tuberculosis can be classified as-
