Hospitalisation
Also: hospitalization, hospital admission, inpatient admission, admissions
Admission to hospital, counted as an event. It is not a disease but a record of one severe enough to need inpatient care, which is what makes it available in administrative data for whole populations and useful as a hard endpoint.
Why it matters indoors
Admission data has two properties that nothing else in this vocabulary combines: it is recorded for everyone, and it marks severity. A symptom questionnaire tells what people report; an admission tells what a clinician judged serious enough to treat inside a hospital, and it is dated to the day.
That precision is what makes it the endpoint of choice for studies of short-term exposure, where daily admission counts are set against daily exposure. Indoors, it appears mainly where a household characteristic — cooking fuel, heating, crowding — is linked to later admissions in a cohort.
Three limits belong with any such result. Admission depends on access to care and on admission policy as much as on illness, so it is not comparable between health systems; the diagnosis attached to it is an administrative code; and it counts events rather than people, so one patient admitted repeatedly weighs as heavily as several. Coridum records the diagnosis category and the counting rule the study used.

Each row is one Finding — a sentence as printed in one study, recorded with its page in the Coridum Knowledge Base. Follow the Finding number for the exact wording and the citation. Checked says who verified the row: machine means every automatic check passed and the surrounding text was read; person means someone read the sentence in the document. Rows are re-checked by a person over time. The studies are curated in the Coridum Knowledge Base; the reading of them together is a Claim, shown separately.
