India has made rapid strides in the health sector since independence. However, various eye opening data from NFHS clearly indicate that access to healthcare still remains a challenge.While the health statistics of rural India continue to be poor, the health status and access to health for the poor in urban slum dwellers has surfaced to be equally deplorable and have less than 4% of government primary healthcare facilities.In such a scenario a mobile healthcare services delivery system is the most practical mechanism. And in subscription to this view, Ramayush Foundation of Social Welfare Trust has initiated the Smile on Wheels programme. This is a unique mobile hospital programme that seeks to address problems of mobility, accessibility and availability of primary healthcare with a special focus on children and women, in urban slums and remote rural areas.The Ramayush Foundation of Social Welfare Trust on Wheels programme has so far provided free healthcare services to more children and families.
