ABSTRACT
Medical service systems have become a burden to many governments due to a shortage in medical practitioners, a rapidly aging population, a shortage of medical resources in regional communities, and overburdened public health insurance systems. Particularly, the shortage of healthcare workers has brought a big burden to both developing and developed nations. For example, Japan had 2.2 doctors and 9.5 nurses per 1000 people in 2009 according to the Organisation for Economic Cooperation and Development (OECD) [1]. However, in India the proportions were 0.7 doctors and 0.9 nurses per 1000 people. The health worker shortage has reached a crisis level in 57 countries [2]. The demand for medical care is much higher in urban areas. The burden among the developed countries is the healthcare, while among developing countries it is the economic imbalance.
