I now have all the necessary information from K. Park's textbook. Here is a complete answer:
DOTS Provider - As Per K. Park's Textbook of Preventive and Social Medicine
What is a DOT Provider?
A DOT (Directly Observed Treatment) provider is the person who watches the TB patient swallow every dose of anti-TB drug in their presence. This is the core operational mechanism of the DOTS strategy under India's National TB Elimination Programme (NTEP, previously RNTCP).
- During the intensive phase: A health worker or other trained person observes drug intake directly at each dose.
- During the continuation phase: The first dose of each week is swallowed in the presence of the DOT provider, and compliance for the remaining doses is verified by return of the empty multiblister combipack.
(Park's Textbook of Preventive and Social Medicine, p. 219 - DOTS Chemotherapy section)
Who Can Be a DOT Provider?
According to K. Park, a DOT provider can be either:
- A health care worker (HCW) - from the public health system (ANM, ASHA, LHV, health worker at sub-centre or PHI)
- A community volunteer - a trained non-health-system person from the community
The DOT centre can be located at:
- Sub-centre level (health system)
- In the community itself
The DOT provider is identified in consultation with the patient - this is a key point emphasizing patient-centred care.
(Park's Textbook, p. 225 - "Providing health education and counselling to patient and family members")
Specific Mention - ASHA as DOT Provider
K. Park specifically lists among ASHA's roles and responsibilities:
"She will be a provider of directly observed treatment short-course (DOTS) under revised national tuberculosis control programme."
(Park's Textbook, p. 579 - Role and responsibilities of ASHA)
Training of DOT Provider
The DOT provider must be given training for:
- Drug administration
- Identification of adverse effects during treatment
- Frequency of follow-up
The DOT Provider in NIKSHAY System
Under the NIKSHAY IT surveillance system, the DOT provider details are mandatorily recorded alongside TB patient registration, diagnosis details, HIV status, follow-up, contact tracing, and treatment outcomes.
Summary Table
| Category | Examples |
|---|
| Health care worker (public sector) | ANM, ASHA, LHV, health worker at PHI/sub-centre |
| Community volunteer | Trained non-HCW from community, acceptable to patient |
| Key principle | Identified in consultation with patient |
| Location of DOT | Sub-centre or community DOT centre |
Key exam point: A DOT provider is NOT restricted to health workers - a trained community volunteer is equally acceptable. The selection is patient-centred, meaning the patient has a say in who their DOT provider will be. This flexibility is what makes DOTS operationally feasible in field settings.
