Science and Technology in Healthcare: India

Posted by on

 


1) India Knowledge System and Emergence

  • Ancient Roots – India has a long tradition of health sciences:

    • Ayurveda, Siddha, and Unani systems emphasized holistic wellness.

    • Sushruta Samhita (surgical techniques) and Charaka Samhita (medicine) reflect early medical science.

  • Colonial Period – Introduction of modern hospitals, medical colleges, and Allopathy alongside traditional systems.

  • Integration – Post-independence, India recognized both modern medicine and Indian Knowledge Systems (IKS) through councils like AYUSH.

2) History of Innovation in India

  • Pre-independence – indigenous vaccines for plague and cholera by scientists like Waldemar Haffkine.

  • Green Revolution era (1960s–70s) – nutritional health linked with scientific farming.

  • Pharmaceutical Growth – India developed strong capacity in generic medicines, earning the title “Pharmacy of the World.”

3) Post-Independence Boost

  • Creation of ICMR (Indian Council of Medical Research) and CSIR labs for health R&D.

  • AIIMS (1956) – benchmark medical research and teaching institute.

  • Establishment of Public Sector Undertakings for drugs, vaccines, and medical equipment.

  • National Health Programs – polio eradication, malaria control, family planning with scientific input.

4) Present Status

  • Healthcare Market – India among the largest pharma producers, exporting to 200+ countries.

  • Medical Devices Industry – still import-dependent (70–80%), though growing under “Make in India.”

  • Digital Health – rapid adoption of telemedicine, e-Sanjeevani platform, CoWIN vaccination app, and Ayushman Bharat Digital Mission (ABDM).

  • Biotech & Genomics – India advancing in COVID-19 vaccines (Covaxin, Covishield), genome sequencing, and stem cell research.

5) Institutions Involved

  • ICMR – apex medical research body.

  • CSIR (Council of Scientific & Industrial Research) – pharma, biotech, diagnostics.

  • DBT (Department of Biotechnology) – vaccine, genomics, bioinformatics.

  • DST (Department of Science & Technology) – technology support.

  • NITI Aayog – policy think-tank for innovation.

  • AYUSH Ministry – traditional medicine promotion.

  • AIIMS, PGI, NIMHANS, IITs, IISc – medical + engineering integration.

6) Research and Development Expenditure

  • India spends ~0.7% of GDP on R&D (much lower than global leaders like USA ~2.8%, Israel >4%).

  • Within this, health R&D is about 3–4% of total R&D spending.

  • Private sector contribution is increasing, especially in biotech start-ups and digital health solutions.

7) Government Measures and Policies

  • National Health Policy, 2017 – emphasizes innovation, affordable drugs, and universal health coverage.

  • National Digital Health Mission (ABDM, 2020) – creates a digital health ID and integrated health records.

  • Production Linked Incentive (PLI) Scheme – for medical devices, APIs, bulk drugs.

  • National Biotechnology Development Strategy, 2021–25 – promotes innovation in vaccines, diagnostics, genomics.

  • Ayushman Bharat Yojana – combines technology with universal health insurance.

  • Make in India + Startup India – boosts med-tech innovation.

8) Private Sector Involvement

  • Pharmaceuticals – firms like Sun Pharma, Cipla, Dr. Reddy’s, Serum Institute lead vaccine and drug exports.

  • Startups – Practo, 1mg, PharmEasy, CureFit driving telehealth, e-pharmacy, fitness-tech.

  • Corporate Hospitals – Apollo, Fortis, Narayana Health adopting AI, robotics, tele-ICU.

  • Med-tech Innovation – startups building low-cost ventilators, portable ECGs, and diagnostic kits.

9) Essential Equipment and Usage

  • Ventilators – critical for ICU care (especially COVID-19).

  • CT & MRI Scanners – imaging diagnostics.

  • Portable Ultrasound & ECG devices – useful in rural areas.

  • Point-of-Care Testing Kits – for TB, malaria, COVID, diabetes.

  • Robotics & AI Tools – precision surgery, predictive diagnostics.

  • Wearables – smartwatches monitoring heart rate, oxygen, fitness.

  • ICMR's Cerebro: near infrared spectroscopy of the brain with portable device. (latest launched)


10) Need for Diagnosis and Innovation

  • India faces a dual burden – communicable diseases (TB, malaria) + non-communicable diseases (diabetes, cancer, cardiovascular).

  • Rural areas lack specialists; affordable diagnostics are critical.

  • Emerging challenges: antimicrobial resistance, pandemics, lifestyle diseases → need continuous innovation.

11) Significance and Challenges

Significance

  • Affordable healthcare for 1.4 billion people.

  • Global role as supplier of cheap generics and vaccines.

  • Strategic importance – self-reliance in medical devices, reducing import dependence.

Challenges

  • Low R&D spending compared to global peers.

  • Infrastructure gaps in rural healthcare.

  • Import dependence for medical equipment and high-end devices.

  • Brain drain of top medical researchers.

  • Regulation – ensuring safety and efficacy of new drugs/diagnostics.

12) Way Forward

  • Increase R&D spending to at least 1.5–2% of GDP with a dedicated health-tech share.

  • Strengthen public-private partnerships (PPPs) for research and affordable equipment.

  • Promote indigenous manufacturing of medical devices under Atmanirbhar Bharat.

  • Leverage AI, big data, and telemedicine for rural health outreach.

  • Skill development in biomedical engineering and biotech.

  • Global collaboration in pandemic preparedness, vaccine research, and diagnostics.

  • Sustainability – eco-friendly hospitals, renewable-powered medical equipment.

Conclusion

India’s healthcare science has evolved from ancient Ayurveda to AI-driven precision medicine. The pandemic showed India’s potential in innovation (vaccines, digital platforms), but also exposed gaps in R&D and equipment self-reliance. A balanced approach of investment, innovation, and inclusivity can make India a global leader in health technology while ensuring equitable care for its citizens.
