Healthcare has become one of India’s largest sectors - both in terms of revenue and employment. Healthcare comprises hospitals, medical devices, clinical trials, outsourcing, telemedicine, medical tourism, health insurance and medical equipment The Government, public healthcare system comprises limited secondary and tertiary care institutions in key cities and focuses on providing basic healthcare facilities in the form of primary healthcare centers in rural areas. The private sector provides majority of secondary, tertiary and quaternary care institutions with a major concentration in metros, tier I and tier II cities. India's competitive advantage lies in its large pool of well-trained medical professionals. India is also cost competitive compared to its peers in Asia and Western countries. The cost of surgery in India is about one-tenth of that in the US or Western Europe. The healthcare market can increase three fold to Rs 8.6 trillion (US$ 133.44 billion) by 2022. India is experiencing 22-25 per cent growth in medical tourism and the industry is expected to double its size from present US$ 3 billion to US$ 6 billion by 2018. There is a significant scope for enhancing healthcare services considering that healthcare spending as a percentage of Gross Domestic Product is rising. The government’s expenditure on the health sector has grown to 1.4 per cent in FY18E from 1.2 per cent in FY14. The Government of India is planning to increase public health spending to 2.5 per cent of the country's GDP by 2025.
