Resource Profile: ObservationBPLite

Introduction

The ObservationBPLite profile represents the vital sign Blood pressure and is a profile created from the resource Observation. The vital sign blood pressure can hold both the value of the diastolic and systolic blood pressure of the patient. The profile is derived from the standard FHIR profile Vital Signs which makes the profile compliant with the FHIR standardized way of communicating vital sign data.

Intended Use

The ObservationBPLite profile is used for communicating the value of the patient blood pressure in mm[Hg]. If either the systolic or diastolic blood pressure is not included, a value must be sent in Observation.component.dataAbsentReason. In COSMIC it is mapped to the internal archetype for blood pressure.

The API can be used to create and read patient blood pressure information from/to COSMIC.

Create Blood Pressure

Patient Generated

• The patient generated data is ordered by a care giver and there should be a responsible unit sent together with the data.

Healthcare Professional

• To create data using this API, you should be a healthcare professional with a specified HSA ID. This professional should have their assignment, and be connected, to the specified care unit. The care unit should also be specified with a HSA ID.
• The intended use is in first hand that the API is used within the same caregiver. The user and the specified care unit should exist in COSMIC as well as in the external system.

Read Blood Pressure

• The intended use for reading data with this API 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 "data copying" between caregivers, patient consent must be handled outside the API.
