Objectives: Increasing use of medical devices outside of healthcare facilities inevitably requires connectivity and interoperabilitybetween medical devices and healthcare information systems. To this end, standards have been developed and usedto provide interoperability between personal health devices (PHDs) and external systems. ISO/IEEE 11073 standards andIHE PCD-01 standard messages have been used the most in the exchange of observation data of health devices. Recently,transmitting observation data using the HL7 FHIR standard has been devised in the name of DoF (Devices on FHIR) andadopted very fast. We compare and analyze these standards and suggest that which standard will work best at the differentenvironments of device usage. Methods: We generated each message/resource of the three standards for observed vital signsfrom blood pressure monitor and thermometer. Then, the size, the contents, and the exchange processes of these messagesare compared and analyzed. Results: ISO/IEEE 11073 standard message has the smallest data size, but it has no ability tocontain the key information, patient information. On the other hand, PCD-01 messages and FHIR standards have the fieldsfor patient information. HL7 DoF standards provide reusing of information unit known as resource, and it is relatively easyto parse DoF messages since it uses widely known XML and JSON. Conclusions: ISO/IEEE 11073 standards are suitable fordevices having very small computing power. IHE PCD-01 and HL7 DoF messages can be used for the devices that need to beconnected to hospital information systems that require patient information. When information reuse is frequent, DoF is advantageousover PCD-01.
