HL7
Health Level Seven or HL7 refers to a set of international standards for transfer of clinical and administrative data between software applications used by various healthcare providers. These standards focus on the application layer, which is "layer 7" in the OSI model. The HL7 standards are produced by Health Level Seven International, an international standards organization, and are adopted by other standards issuing bodies such as American National Standards Institute and International Organization for Standardization. Hospitals and other healthcare provider organizations typically have many different computer systems used for everything from billing records to patient tracking. All of these systems should communicate with each other (or "interface") when they receive new information, or when they wish to retrieve information, but not all do so. HL7 International specifies a number of flexible standards, guidelines, and methodologies by which various healthcare systems can ...

Fast Healthcare Interoperability Resources
The Fast Healthcare Interoperability Resources' (FHIR, pronounced "fire") standard is a set of rules and specifications for exchanging electronic health care data. It is designed to be flexible and adaptable, so that it can be used in a wide range of settings and with different health care information systems. The goal of FHIR is to enable the seamless and secure exchange of health care information, so that patients can receive the best possible care. The standard describes data formats and elements (known as "resources") and an application programming interface (API) for exchanging electronic health records (EHR). The standard was created by the Health Level Seven International (HL7) health-care standards organization. FHIR builds on previous data format standards from HL7, like HL7 version 2.x and HL7 version 3.x. But it is easier to implement because it uses a modern web-based suite of API technology, including a HTTP-based RESTful protocol, and a choice of JSON, XML or RDF ...

Clinical Document Architecture
The HL7 Clinical Document Architecture (CDA) is an XML-based markup standard intended to specify the encoding, structure and semantics of clinical documents for exchange. In November 2000, HL7 published Release 1.0. The organization published Release 2.0 with its "2005 Normative Edition." Content CDA specifies the syntax and supplies a framework for specifying the full semantics of a clinical document, defined by six characteristics: # Persistence # Stewardship # Potential for authentication # Context # Wholeness # Human readability CDA can hold any kind of clinical information that would be included in a patient's medical record; examples include: * Discharge summary (following inpatient care) * History & physical * Specialist reports, such as those for medical imaging or pathology An XML element in a CDA supports unstructured text, as well as links to composite documents encoded in pdf, docx, or rtf, as well as image formats like jpg and png. It was developed using the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CCOW
In the context of Health informatics, CCOW (''pr'' /seacow/) or Clinical Context Object Workgroup is a Health Level Seven International standard protocol designed to enable disparate applications to synchronize in real time, and at the user-interface level. It is vendor independent and allows applications to present information at the desktop and/or portal level in a unified way. CCOW is the primary standard protocol in healthcare to facilitate a process called "Context Management." Context Management is the process of using particular "subjects" of interest (e.g., user, patient, clinical encounter, charge item, etc.) to 'virtually' link disparate applications so that the end-user sees them operate in a unified, cohesive way. Context Management can be utilized for both CCOW and non-CCOW compliant applications. The CCOW standard exists to facilitate a more robust, and near "plug-and-play" interoperability across disparate applications. Context Management is often combined with S ...

Continuity Of Care Document
The Continuity of Care Document (CCD) specification is an XML-based markup standard intended to specify the encoding, structure, and semantics of a patient summary clinical document for exchange. Structure The CCD specification is a constraint on the HL7 Clinical Document Architecture (CDA) standard. The CDA specifies that the content of the document consists of a mandatory textual part (which ensures human interpretation of the document contents) and optional structured parts (for software processing). The structured part is based on the HL7 Reference Information Model (RIM) and provides a framework for referring to concepts from coding systems, such as SNOMED or LOINC. The patient summary contains a core data set of the most relevant administrative, demographic, and clinical information facts about a patient's healthcare, covering one or more healthcare encounters. It provides a means for one healthcare practitioner, system, or setting to aggregate all of the pertinent data ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electronic Medical Record
An electronic health record (EHR) is the systematized collection of patient and population electronically stored health information in a digital format. These records can be shared across different health care settings. Records are shared through network-connected, enterprise-wide information systems or other information networks and exchanges. EHRs may include a range of data, including demographics, medical history, medication and Allergy, allergies, immunization status, laboratory test results, radiology images, vital signs, personal statistics like age and weight, and billing information. For several decades, electronic health records (EHRs) have been touted as key to increasing of quality care. Electronic health records are used for other reasons than charting for patients; today, providers are using data from patient records to improve quality outcomes through their care management programs. EHR combines all patients demographics into a large pool, and uses this informatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Structured Product Labeling
Structured Product Labeling (SPL) is a Health Level Seven International (HL7) standard which defines the content of human prescription drug labeling in an XML format. The "drug labeling" includes all published material accompanying a drug, such as the Prescribing Information which contains a great deal of detailed information about the drug. As of Release 4 of the SPL standard, 22,000 FDA informational product inserts have been encoded according to the standard. SPL documents contain both the content of labeling (all text, tables and figures) for a product along with additional machine readable information (drug listing data elements). Drug listing data elements include information about the product (proprietary and nonproprietary names, ingredients, ingredient strengths, dosage forms, routes of administration, appearance, DEA schedule) and the packaging (package quantity and type). Background Since October 31, 2005, labeling submissions to the FDA's Center for Drug Evaluatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gello Expression Language
The GELLO Expression Language was started in 2001 and introduced in 2002; in 2005, GELLO was adopted as an international standard by Health Level Seven International and ANSI for a decision support language. GELLO Release 2 was completed and approved by ANSI in June 2010. The GELLO specifications have been developed in coordination with the HL7 Clinical Decision Support TC (CDSTC) GELLO is a class-based object-oriented programming language and a relative of the Object Constraint Language (OCL). OCL is a well-developed constraint language that makes it attractive for use as an expression language. The intention was for GELLO to evolve as a standard query and expression language for decision support. GELLO creates the potential for many decision support options, as the full array of atomic patient data is greatly accessible to complement better, safer clinical decision-making by health professionals. Furthermore, this enables specialist clinicians to customize their current systems a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arden Syntax
Arden syntax is a markup language used for representing and sharing medical knowledge. This clinical and scientific knowledge language is used in an executable format by clinical decision support systems to generate alerts, interpretations, and to screen and manage messages to clinicians. This syntax is used to share medical knowledge within and across many health service institutions. Rule sets, called Medical Logic Modules (MLMs), comprise enough logic to make a single medical decision. Medical logic modules are written in Arden syntax, and are called by a program – an event monitor – when the condition they are written to help with occurs. Arden syntax was formerly a standard under ASTM, published in 1992, and is now part of Health Level Seven International. Arden syntax version 2.0 was published by HL7 in 1999. Arden syntax version 2.10 is the current version. History Arden Syntax and its first applications were conceived and developed as the primary deliverables of a ...

OSI Model
The Open Systems Interconnection model (OSI model) is a conceptual model that 'provides a common basis for the coordination of SOstandards development for the purpose of systems interconnection'. In the OSI reference model, the communications between a computing system are split into seven different abstraction layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. The model partitions the flow of data in a communication system into seven abstraction layers to describe networked communication from the physical implementation of transmitting bits across a communications medium to the highest-level representation of data of a distributed application. Each intermediate layer serves a class of functionality to the layer above it and is served by the layer below it. Classes of functionality are realized in all software development through all and any standardized communication protocols. Each layer in the OSI model has its own well-defined funct ...
