Interoperability in Healthcare: standards to exchange information

healthcare Interoperability
To achieve the smoothest possible exchange of information, it is essential to adopt standards for the different health systems to share. For this reason, several organizations seeking to unify interoperability criteria have arisen, such as HL7 International, HIMSS o NEMA.

    In messaging for example, they have developed standards that define the format and structure of data elements to facilitate communication between different clinical systems. Among these are:
  • HL7 V2.X, HL7 V3 to exchange demographic, clinical and administrative data.
  • DICOM (Digital Imaging and Communications in Medicine) that defines the way to communicate diagnostic images and information associated with these.
  • ASC-X12, which has been designed to exchange procedures, patient eligibility and benefit payments.
  • IEEE 1073, which determines the messages to exchange data with biomedical instrumentation equipment.
    • With regard to health terminology or data standards that add the semantic component, vocabularies and codes have been developed to label clinical concepts such as diseases, problem lists, diagnoses, drugs, techniques and procedures, analytical determinations and laboratories, among others. Some of these are:
  • ICD-10 or the International Classification of Diseases, that defines a catalog of diagnoses and procedures for statistical purposes, billing, costs and paperwork.
  • LOINC that is more oriented to laboratory tests, metrics and clinical observations.
  • SNOMED CT, which is a large ontology of biomedical concepts with descriptions, relationships and grammar to build clinical expressions.
  • Will wearable devices make us healthier?

    the Economist - wearable devices(The ECONOMIST) – Health- and life-insurance companies seem to think wearable devices can actually make users healthier. They are increasingly underwriting the cost of a range of wearables, including devices from Fitbit, Garmin and Polar.

    Aetna and UnitedHealthcare, two big American health insurers, recently created a plan that subsidised the cost of Apple’s pricey watch. Customers of other insurers willing to upload their movement data can obtain a discount on health or life insurance. The more active they are, the greater the financial reward.

      Yang Zheng, the boss of Ping An Health Insurance in Shanghai, says that 1.5m customers are already uploading activity data every day. But are these efforts any more than a gimmick? Wearables have long been a bit of a joke, with some complaining that their “time to drawer”—the time it takes for people to lose interest and abandon them—can be measured in months.
