Aim and objective
To highlight the need for post-treatment rehabilitation of TB patient; including social psychological and economic aspects.
Methods
Patient interaction, informal interviews, field observations and secondary research.
Results
The side effects of TB medication (especially DR-TB) are sometimes extreme, and require extensive therapy and/or rehabilitation. Some side effects such as hearing-loss are often permanent. Nutritional support is another key factor that receives little attention in national programs.
Conclusion
Therefore despite having completed treatment, many people continue to suffer. Hence it is necessary that robust systems for post-treatment rehabilitation are put in place, and are designed based on the needs of those affected. Peer to peer counselling can be a low-cost high-impact strategy to address some of these issues.
