Resource Profile: ObservationWaistCircumferenceLite

Introduction

The ObservationWaistCircumferenceLite profile represents the parameter Waist circumference and is a profile created from the resource Observation which makes the profile compliant with the FHIR standardized way of communicating vital sign data. Waist circumference is an observation where a measurement taken around the abdomen at the level of the umbilicus (belly button).

Intended Use

The profile ObservationWaistCircumferenceLite is used for communicating an entry of a patient's measurement taken around the abdomen at the level of the umbilicus (belly button), by sending a value in the element observation.value.

Read Waist Circumference

Intended use is in first hand that the API is applied for direct access and should not be used to transfer data between caregivers. If it should be used for copying inbetween care givers patient consent must be handeled outside the API.

Error Codes

In the table below, a few error messages specific for observations are listed.

The profile ObservationWaistCircumferenceLite is used for communicating an entry of a patients arms span by sending a value in the element observation.value. The API can be used to read patient armspan information from COSMIC.
