Context: Tamil Nadu has significantly reduced TB-related deaths by implementing the TN-KET (TB Death-Free Initiative) using a simple triage tool and a differentiated care model.
About TN – KET Program:
- What is TN-KET?
- TN-KET (Kasanoi Erappila Thittam) is a state-level TB mortality reduction initiative launched by Tamil Nadu in 2022, focused on early detection and differentiated care for severe TB cases.
- Key Features:
-
- Paper-Based Triage Tool: Assesses 5 quick parameters (BMI, oxygen level, respiratory rate, leg swelling, ability to stand) to classify patients as “severely ill.”
- Fast-Track Care: 98% of identified severe cases admitted within 7 days.
- Severe TB Web App: Calculates mortality risk and helps guide urgent interventions.
- Simplified Assessment: No lab needed and saves 6–7 days over older 16-parameter tools.
- Differentiated Care Model: Offers customized treatment based on age, BMI, severity, and comorbidities.
- Significance:
-
- Reduction in Early Deaths: TN saw a 20% drop in early TB deaths within 6 months of implementation.
- National Replicability: Sets a scalable model for high-burden TB states, aligned with India’s National TB Elimination Programme (NTEP).
- Data-Driven Governance: Leverages real-time triage for targeted interventions.
