| Draft as of 2026-10-14 | Computable Name: Haau3Observation | |||
Something measured or recorded about a care recipient — a lab result, a vital sign, a survey answer, an exam finding. Delivered records always state who they are about and what kind of record they are; where the kind could not be determined it is stated as unknown rather than invented. Categories the source system supplied are always preserved.
