The military infirmary 4th class at Solok (West Sumatra) was 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 Solok had on average 4 patients.

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 Solok infirmary is then 16 patients, whereas 355 have been admitted that year. The situation by the end of the year 1890 is a presence of 15 patients.
