The infirmary 1st class at Bogor, former spelling Buitenzorg, 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 Buitenzorg had on average 19 inpatients. The infirmary was part of the Military Medical Service (MGD) which in that same year all over the archipelago treated an average of 4,244 inpatients. Some 25 year later, the Annex D of the Koloniaal Verslag 1890 reports a total  of 3,359 inpatients for the whole of the Netherlands Indies. In the meantime the infirmary has been upgraded to hospital. The average occupation rate of the Buitenzorg hospital is then 359 Europeans and 377 indigenous patients, whereas 474 patients have been admitted that year. On 31 December 1890, 34 European and 34 indigenous patients were present.

In the Koloniaal Verslag 1920 (p. 137) it is mentioned that at the Buitenzorg military hospital a new separate department has been built to care for Plague victims.

The directing Health Officer 2nd class, W. van der Veer reports about the MGD in the period 1911-1934 and mentions the transformation of a number of military hospitals into ziekenzalen (Infirmaries), among others this happens to the Buitenzorg hospital in 1932. See: Geneeskundig Tijdschrift voor Nederlandsch-Indie (GTNI) 76 (1936), 224.
