# IoT on FHIR - This is a simplified use case for IoT devices and user (patient and care provider) applications integrated with FHIR server for data sharing. - Following graphics is the simplified integration framework: ![](https://i.imgur.com/nHjozta.png) - The framework is simplified according to [Continua Health Alliance 4 tiers integration framework](https://hackmd.io/2QFjeso0QF6w0QiR9WiXxA?view#Continua-Health-Alliance-4-tiers-integration-framework) - In the framework, FHIR server that supports FHIR APIs as a data sharing center. Clients may use FHIR APIs to create and retrieve FHIR resources with FHIR server. ## [Steps for IoT on FHIR](https://hackmd.io/6oPPS1OkREOkbrmccflyQg?view) 1. User Application post patient and device to FHIR server 2. Device get the affixed patient ID 3. Device post vital sign(observation) 4. User application get the patient's vital sign (observation) ## Continua Health Alliance 4 tiers integration framework ![](https://i.imgur.com/b1IxUFA.png) ## Standards - Data format specifications : [FHIR observation](https://build.fhir.org/observation.html)、[FHIR Personal Health Device Implementation Guide](http://build.fhir.org/ig/HL7/PHD/) - Integration framework and Security :[XDS on FHIR](http://www.ringholm.com/column/combining_ihe_xds_mhd_and_fhir.htm)、[FHIR security](http://www.hl7.org/Fhir/security.html)、[IHE IUA](https://ihe.github.io/ITI.IUA/IHE_ITI_Suppl_IUA) ## PHR and EHR integration framework ![](https://i.imgur.com/5Uq6z7y.png) - Personal Health Record (PHR) is a patient-centred organisational system.
