Description

Observation

This topic describes information for the Observation resource.

Overview

The Observation resource provides measurements or simple assertions about a patient. Observations are crucial to supporting diagnoses, monitoring progress, and establishing baselines or trends. Most observations are simply a name and value or result, but some observations, such as blood pressure, group other observations together logically. Examples of common observations are laboratory results (blood sugar, hemoglobin), vital signs (temperature, blood pressure), personal characteristics (height, weight), and social history (tobacco or alcohol use, employment status).Pathology reports, radiology reports, and other textual reports should be represented by the DiagnosticReport resource.

The following fields are returned if valued:

• ID

• Status

• Category (laboratory, social history)

• Patient

• Patient encounter

• Effective date/time (collection date/time for laboratory)

• Issue date/time (date/time observation made available, entered, verified)

• Observation (name or text)

• Observation value or result

• For Observations with valueQuantity

  • Quantity comparator (<, <=, >, >=)

  • Quantity units

• Interpretation (abnormal flagging)

• Reference range

• Comments

• Related Observations (currently for limited use cases)

• Components (eg: systolic and diastolic for blood pressure)
