The military infirmary 3rd class at Rantau (SE Kalimantan) is mentioned in the publication of D. Schoute “De Geneeskunde in Nederlandsch-Indie in de 19e eeuw”, GTNI 75 (1935) 10, 827. The article refers to a survey of  all the military facilities in 1867 . In that year the infirmary at Rantau had on average 10 inpatients. The infirmary was part of the Military Medical Service (MGD),  which in 1867 (the year of the survey of all military facilities) managed a total of 79 facilities (3 large military hospitals, 35 garrison hospitals and 41 infirmaries) with on average 4,244 occupied beds.

Some 25 years later, the Annex D of the Koloniaal Verslag 1890 reports a total  of 3,358 inpatients by the end of that year, whereas 52,631 patients have been admitted for the whole of the Netherlands Indies. The report concerns 28 military hospitals, 54 ziekenzalen (infirmaries) and 6 specialized facilities. The average occupation rate of the Rantau Infirmary is not mentioned, maybe in the absence of an officer of health.

In 1899 the situation of military health facilities was: 30 hospitals, 56 infirmaries and 5 specialized facilities, such as reconvalescent centers and leprosy asylums. The total number of admittances was in 1899: 57,071 and the number of present inpatients by the end of 1899: 3,731. These figures were for the Rantau infirmary: 4 admittances and no patients present on 31 December 1899.
