Feasibility and Accuracy of Tele-spirometry: A Community-based Approach in Rural India

This is the authors' abstract. We don't add key points for this paper.

Background: Spirometry plays a pivotal role in detecting and managing lung diseases, yet its availability in primary healthcare settings, especially in rural areas, remains limited. The advent of portable tele-spirometry holds promise in bridging this gap. The present study was conducted to assess the utility of tele-spirometry in community-based management of respiratory diseases. Materials and Methods: The tele-spirometer recorded and stored data on a web server accessible to physicians via a telemedicine application. Clinical validation was conducted on 366 individuals (mean ± SD age, 31.49 ± 20.05 years) residing in the periphery of Chandigarh, India. Data were then transmitted to physicians in the Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India. Results: A strong correlation was observed between traditional spirometry and portable tele-spirometry. The portable spirometer expedited diagnosis, reduced costs, and facilitated prompt treatment initiation. Our study achieved 80% good-quality spirometry readings with only 20% moderate quality. Patient satisfaction was notably high, with approximately ~95% patients reporting satisfaction. Conclusion: Tele-spirometry is a portable, cost-effective, and convenient tool for the diagnosis and monitoring of respiratory diseases, significantly enhancing quality and accessibility, especially in rural areas. Furthermore, it paves the way for potential home-based consultations for chronic respiratory disease management in the future.
