Current Healthcare Landscape

Healthcare Challenges in India:

Doctor Shortage: 0.8 doctors per 1,000 people vs WHO recommended 1:1,000
Rural Access: 70% of population lives in rural areas with limited healthcare
Diagnostic Errors: 15-20% misdiagnosis rate in primary care
Cost Burden: 60% of healthcare expenses are out-of-pocket
Infrastructure Gap: Limited advanced medical equipment in rural areas
Specialist Shortage: Critical shortage of radiologists, pathologists, and specialists
