- formalnot comparablemedicineOf an infection or its cause: arising from the environment of, or treatment in, a hospital.First known use early 19th c.
Nosocomial infections are infections occurring during hospitalization that were not present, and not incubating, at the time of hospital admission[…]. All patients in an ICU are at increased risk of developing nosocomial infections[…].

Berenson, “Outcomes of Intensive Care: Medical Benefits and Cost Effectiveness”, in Intensive Care Units (ICUs): Clinical Outcomes, Costs, and Decisionmaking (Health Technology Case Study; 28), Washington, D.C.: Office of Technology Assessment, Congress of the United States, →OCLC, page 405 more examples
It is a febrile disease accompanied by symptoms quite peculiar to it. […] There is a peculiar conformity between it and nosocomial fever, or typhus of prisons, described by Pringle [i.e., Sir John Pringle, 1st Baronet], a disease of a complicated nature, and named by Pinal adynamic & ataxic fever. We shall soon see that both may originate from analogous causes, and that a contagion not being sufficiently strong for developing the true nosocomial fever among healthy persons, may, nevertheless, produce hospital gangrene.
1815 November, S[ebald] J[ustinus] Brugmans, “Memoir on the State and Composition of the Atmosphere, Considered as the Cause of the Hospital Gangrene, or Putrescence among the Wounded”, in The London Medical and Physical Journal. […], volume XXXIV, number 5 (number 201 overall), London: Printed for the proprietors, by J. and C. Adlard, […]; published by J. Souter, […], →OCLC, § 10.2, page 398Professor Laveran furnishes this narration as a specimen of the injurious effects which nosocomial influences exert upon otherwise benign affections. The return of troops from the Italian war had the effect of producing great accumulations of troops in the military Hospitals. […] [W]e find that some [febrile diseases], as malarial diseases for example, are benefited by the very fact of residence within an Hospital, and are but little subjected to nosocomial influences.

1880 October 20, Jules Rochard, translated by B. A. Watson, “[Translations. From the French.] New Modes of Surgical Treatment. (‘Histoire de la Chirurgie Française’ par le Docteur Jules Rochard. Edit. 1875.)”, in Tho[ma]s F. Rumbold, editor, The Saint Louis Medical and Surgical Journal, volume XXXIX, number 8, St. Louis, Mo.: [s.n.], →OCLC, page 488The most common nosocomial infections are urinary tract infections (42 percent), followed by surgical wound infections (24 percent), pneumonia (10 percent), and infections of the bloodstream (bacteremia) (5 percent). […] Almost three-quarters of nosocomial infections occur among patients undergoing surgery […] The most difficult obstacle to the reliable measurement of nosocomial infections is the lack of standardized case finding.
1988 June, Office of Technology Assessment, Congress of the United States, “Adverse Events”, in The Quality of Medical Care: Information for Consumers (OTA-H-386), Washington, D.C.: U.S. Government Printing Office, →OCLC, page 109, column 1For many years we have known that patients at high risk for nosocomial rhinosinusitis are those who require extended periods of intensive care with prolonged endotracheal intubation or nasogastric tubing[…]. Nasotracheal intubation has a higher risk for nosocomial sinusitis than orotracheal intubation[…].

It is also in part the nosocomial treatment schedules that have drawn our attention to this important field. I suggest that with shock lung we are dealing with a problem of multiple organ failure, not just the lung.

In 1822 he [Étienne Serres] left the Hôtel Dieu for La Pitié, where he remained until he had attained the legal limit of age which compels the nosocomial physicians and surgeons of Paris to retire from office. At this point terminates the strictly medical part of M. Serres' career, during which he gained great distinction as a nosocomial physician, and published several works of value.

Origin
- Proto-Indo-European*kem(H)-“to be tired; to exert oneself”
- Ancient Greekνοσοκομεῖον“hospital, infirmary”
- Late Latinnosocomīum“hospital, infirmary”
- Englishnosocomial
Learned borrowing from Late Latin nosocomīum (“hospital, infirmary”) + English -al (suffix meaning ‘of or pertaining to’ forming adjectives). Nosocomīum is borrowed from Ancient Greek νοσοκομεῖον (nosokomeîon, “hospital, infirmary”), from νοσοκομέω (nosokoméō, “to tend the sick”) + -εῖον (-eîon, suffix forming nouns denoting places); νοσοκομέω (nosokoméō) is from νόσος (nósos, “disease, illness, sickness”) (further etymology uncertain) + κομέω (koméō, “to take care of, look after, tend”) (from Proto-Indo-European *kem(H)- (“to be tired; to exert oneself”)).
