In a quasi‑experimental study, AIIMS Bibinagar in Telangana used drones to transport sputum samples from remote villages to TB testing centres. The intervention, part of the i‑DRONE initiative, reduced out‑of‑pocket expenses from an average of ₹9,451 to just ₹91 and cut the median diagnostic delay from 15 days to 5 days.
Key Developments
- Samples collected at PHCs and sub‑centres were flown by drones to designated TB Units.
- A central command at AIIMS coordinated flights across 11 PHCs, 60 sub‑centres and four TB Units.
- Patients no longer needed to travel 10‑30 km on poor roads to reach GeneXpert or Truenat facilities.
Important Facts
- Study period covered 840 participants: 206 before drone use and 634 after.
- Median patient delay (symptom onset to first medical contact) stayed at 6 days, but prolonged delays fell during the drone phase.
- Before drones, >92 % of patients waited >2 days for results; after drones, 76.3 % received results the next day.
- Average out‑of‑pocket cost dropped from ₹9,451 to ₹90.9, covering travel, food, medical fees and wage loss.
- The research was published in the International Journal of Tuberculosis and Lung Disease.
Exam Relevance
This case illustrates how technology can bridge gaps in ICMR‑led programmes, a topic for GS‑1 (Health) and GS‑3 (Science & Technology). It also highlights challenges of rural health infrastructure, a recurring theme in the National Health Policy and the Sustainable Development Goals, useful for essay and case‑study questions.
Way Forward
Scaling the drone model to other high‑burden districts could further reduce delays and costs. Policy makers should standardise protocols, ensure data security, and integrate drone logistics with existing supply‑chain systems. Training of PHC staff and community awareness will be crucial for sustained impact.
