Before independence a great many organizations ventured on the road of hospital service.
Especially missionary organizations, but also political organizations took initiatives to establish general hospitals or hospitals that were specialized in leprosy, eye diseases, tuberculosis, etc.

In the following, a list of well-known existing establishments will be exposed. They are part of a social organization: “Organisasi Islam, Organisasi Katholik, Organisasi Protestan, Organisasi Hindu or Organisasi sosial”  in general. We will focus on the catholic and protestant organizations especially, because they had in many cases a predecessor in the missionary field. The first 28 hospitals have been established before 1945. The last category are hospitals that have been established after the independence.
