HL7
Health Level Seven, abbreviated to HL7, is a range of global standards for the transfer of clinical and administrative health data between applications with the aim to improve patient outcomes and health system performance. The HL7 standards focus on the application layer, which is "layer 7" in the Open Systems Interconnection model. The 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. There are a range of primary standards that are commonly used across the industry, as well as secondary standards which are less frequently adopted. Purpose Health organizations typically have many different computer systems used to process different patient administration or clinical tasks, such as billing, medication management, patient tracking, and documentation. All of these systems should commun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fast Healthcare Interoperability Resources
The Fast Healthcare Interoperability Resources (FHIR, , like ''fire'') standard is a set of rules and specifications for the secure exchange of 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 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 Resource Description Framework, RDF for data representation. One of its goals is to facilitate interoperability between legacy health care ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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). As of 2021, the GELLO Implementation Guide DSTU was withdrawn from HL7 Version 3 due to inactivity. However, Release 2 of the standard remains as is, despite a low level of use. 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 g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...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 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 single ...

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 Evaluation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Health Record
An electronic health record (EHR) is the systematized collection of electronically stored patient and population 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, EHRs have been touted as key to increasing quality of care. EHR combines all patients' demographics into a large pool, which assists providers in the creation of "new treatments or innovation in healthcare delivery" to improve quality outcomes in healthcare. Combining multiple types of clinical data from the system's health records has helped clinicians identify and st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arden Syntax
Arden syntax is a markup language designed for representing and sharing medical knowledge in a standardized, executable format. It is primarily used by clinical decision support systems to generate alerts, interpretations, and manage information presented to clinicians. This allows for the consistent and efficient application of clinical and scientific knowledge within and across healthcare institutions. The core units of knowledge representation in Arden syntax are Medical Logic Modules (MLMs), which contain the logic necessary to make a single medical decision. These MLMs are triggered by event monitors within clinical systems when specific conditions arise. For example, an MLM might be written to detect a potential drug interaction. It would contain the logic to check if a patient is currently prescribed two medications known to interact negatively. If the conditions are met (i.e., the patient is on both medications), the MLM could trigger an alert to the clinician, providing ...

OSI Model
The Open Systems Interconnection (OSI) model is a reference model developed by the International Organization for Standardization (ISO) that "provides a common basis for the coordination of standards development for the purpose of systems interconnection." In the OSI reference model, the components of a communication system are distinguished in seven abstraction layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. The model describes communications from the physical implementation of transmitting bits across a transmission medium to the highest-level representation of data of a distributed application. Each layer has well-defined functions and semantics and serves a class of functionality to the layer above it and is served by the layer below it. Established, well-known communication protocols are decomposed in software development into the model's hierarchy of function calls. The Internet protocol suite as defined in and is a model of net ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Health Record
A personal health record (PHR) is a health record where health data and other information related to the care of a patient is maintained by the patient. This stands in contrast to the more widely used electronic medical record (EMR), which is operated by institutions (such as hospitals) and contains data entered by clinicians (such as billing data) to support insurance claims. A PHR is intended to provide a complete and accurate summary of an individual's medical history that is accessible online. The health data on a PHR might include patient-reported outcome data, lab results, and data from devices such as wireless electronic weighing scales or (collected passively) from a smartphone. Definition The term "personal health record" is not new. The term was used as early as June 1978, and, in 1956, there was a reference was made to a "personal health log." The term "PHR" may be applied to both paper-based and computerized systems; usage in the late 2010s usually implies an electro ...
