A potential negative outcome from the use of a medicinal product. This is part of the definitional information about a product and is not related to any particular actual use of a medication. An adverse event is any untoward medical occurrence in a patient administered a medicinal profuct and which does not necessarily have to have a causal relationship with the treatment. An adverse reaction is a response to a medicinal reaction which is noxious and unintended and which occurs at doses normally used in man.
Fast Healthcare Interoperability Resources (FHIR) is a draft standard describing data formats and elements (known as “resources”) and an application programming interface (API) for exchanging electronic health records. The standard was created by the Health Level Seven International (HL7) health-care standards organization.
Its goal is to facilitate interoperation between legacy healthcare systems, to make it easy to provide healthcare information to healthcare providers and individuals on a wide variety of devices from computers to tablets to cell phones, and to allow third-party application developers to provide medical applications which can be easily integrated into existing systems.
FHIR provides an alternative to document-centric approaches by directly exposing discrete data elements as services. For example, basic elements of healthcare like patients, admissions, diagnostic reports and medications can each be retrieved and manipulated via their own resource URLs (Uniform Resource Locators). FHIR was supported at an American Medical Informatics Association meeting by many EHR (Electronic health Record) vendors which value its open and extensible nature.
